-			Installing sendmail
-
-**Note**: Starting with sendmail 8.12, sendmail is no longer set-user-ID
-root by default.  As a result of this, you need to install two .cf files.
-See steps 4 and 6 in this document.  We also strongly recommend reading
-sendmail/SECURITY for more installation information.
-
-1. Read all the README files noted in the INTRODUCTION section of the README
-   file in this top-level directory.
-
-2. Create any necessary site configuration build files, as noted in
-   devtools/Site/README.
-
-3. In the sendmail/ directory, run "sh ./Build" (see sendmail/README for
-   details).
-
-4. Change to the cf/cf/ directory (that's not a typo): Copy whichever .mc
-   file best matches your environment to sendmail.mc.  Next, tailor it
-   as explained in cf/README.  Then run
-   "sh ./Build sendmail.cf".
-
-5. Back up your current /etc/mail/sendmail.cf and the sendmail binary (whose
-   location varies from operating system to operating system, but is usually
-   in /usr/sbin or /usr/lib).
-
-6. Install sendmail.cf as /etc/mail/sendmail.cf and submit.cf as
-   /etc/mail/submit.cf.  This can be done in the cf/cf by using
-   "sh ./Build install-cf".
-
-   Please read sendmail/SECURITY before continuing; you have to create a
-   new user smmsp and a new group smmsp for the default installation.
-   Then install the sendmail binary built in step 3 by cd-ing back to
-   sendmail/ and running "sh ./Build install".
-
-7. For each of the associated sendmail utilities (makemap, mailstats,
-   etc.), read the README in the utility's directory if it exists.  When
-   you are ready to install it, back up your installed version and type
-   "sh ./Build install".
-
-8. If you are upgrading from an older version of sendmail and are using any
-   database maps, be sure to rebuild them with the new version of makemap,
-   in case you are now using a different (and thereby incompatible) version
-   of Berkeley DB.

-
-The following are bugs or deficiencies in sendmail that we are aware of
-but which have not been fixed in the current release.  You probably
-want to get the most up to date version of this from ftp.sendmail.org
-in /pub/sendmail/KNOWNBUGS.  For descriptions of bugs that have been
-fixed, see the file RELEASE_NOTES (in the root directory of the sendmail
-distribution).
-
-This list is not guaranteed to be complete.
-
-* Delivery to programs that generate too much output may cause problems
-
-  If e-mail is delivered to a program which generates too much
-  output, then sendmail may issue an error:
-
-  timeout waiting for input from local during Draining Input
-
-  Make sure that the program does not generate output beyond a
-  status message (corresponding to the exit status).  This may
-  require a wrapper around the actual program to redirect output
-  to /dev/null.
-
-  Such a problem has been reported for bulk_mailer.
-
-* Null bytes are not handled properly in headers.
-
-  Sendmail should handle full binary data.  As it stands, it handles
-  all values in the body, but not 0x00 in the header.  Changing
-  this would require a major restructuring of the code -- for
-  example, almost no C library support could be used to handle
-  strings.
-
-* Header checks are not called if header value is too long or empty.
-
-  If the value of a header is longer than 1250 (MAXNAME + MAXATOM - 6)
-  characters or it contains a single word longer than 256 (MAXNAME)
-  characters then no header check is done even if one is configured for
-  the header.
-
-* Header lines which are too long will be split incorrectly.
-
-  Header lines which are longer than 2045 characters will be split
-  but some characters might be lost.  Fix: obey RFC (2)822 and do not
-  send lines that are longer than 1000 characters.
-
-* Sender addresses whose domain part cause a temporary A record lookup
-  failure but have a valid MX record will be temporarily rejected in
-  the default configuration.  Solution: fix the DNS at the sender side.
-  If that's not easy to achieve, possible workarounds are:
-  - add an entry to the access map:
-	dom.ain	OK
-  - (only for advanced users) replace
-
-# Resolve map (to check if a host exists in check_mail)
-Kresolve host -a<OKR> -T<TEMP>
-
-   with
-
-# Resolve map (to check if a host exists in check_mail)
-Kcanon host -a<OKR> -T<TEMP>
-Kdnsmx dns -R MX -a<OKR> -T<TEMP>
-Kresolve sequence dnsmx canon
-
-
-* Duplicate error messages.
-
-  Sometimes identical, duplicate error messages can be generated.  As
-  near as I can tell, this is rare and relatively innocuous.
-
-* Misleading error messages.
-
-  If an illegal address is specified on the command line together
-  with at least one valid address and PostmasterCopy is set, the
-  DSN does not contain the illegal address, but only the valid
-  address(es).
-
-* \231 considered harmful.
-
-  Header addresses that have the \231 character (and possibly others
-  in the range \201 - \237) behave in odd and usually unexpected ways.
-
-* accept() problem on SVR4.
-
-  Apparently, the sendmail daemon loop (doing accept()s on the network)
-  can get into a weird state on SVR4; it starts logging ``SYSERR:
-  getrequests: accept: Protocol Error''.  The workaround is to kill
-  and restart the sendmail daemon.  We don't have an SVR4 system at
-  Berkeley that carries more than token mail load, so I can't validate
-  this.  It is likely to be a glitch in the sockets emulation, since
-  "Protocol Error" is not possible error code with Berkeley TCP/IP.
-
-  I've also had someone report the message ``sendmail: accept:
-  SIOCGPGRP failed errno 22'' on an SVR4 system.  This message is
-  not in the sendmail source code, so I assume it is also a bug
-  in the sockets emulation.  (Errno 22 is EINVAL "Invalid Argument"
-  on all the systems I have available, including Solaris 2.x.)
-  Apparently, this problem is due to linking -lc before -lsocket;
-  if you are having this problem, check your Makefile.
-
-* accept() problem on Linux.
-
-  The accept() in sendmail daemon loop can return ETIMEDOUT.  An
-  error is reported to syslog:
-
-  Jun  9 17:14:12 hostname sendmail[207]: NOQUEUE: SYSERR(root):
-			getrequests: accept: Connection timed out
-
-  "Connection timed out" is not documented as a valid return from
-  accept(2) and this was believed to be a bug in the Linux kernel.
-  Later information from the Linux kernel group states that Linux
-  2.0 kernels follow RFC1122 while sendmail follows the original BSD
-  (now POSIX 1003.1g draft) specification.  The 2.1.X and later kernels
-  will follow the POSIX draft.
-
-* Excessive mailing list nesting can run out of file descriptors.
-
-  If you have a mailing list that includes lots of other mailing
-  lists, each of which has a separate owner, you can run out of
-  file descriptors.  Each mailing list with a separate owner uses
-  one open file descriptor (prior to 8.6.6 it was three open
-  file descriptors per list).  This is particularly egregious if
-  you have your connection cache set to be large.
-
-* Connection caching breaks if you pass the port number as an argument.
-
-  If you have a definition such as:
-
-	  Mport,          P=[IPC], F=kmDFMuX, S=11/31, R=21,
-			  M=2100000, T=DNS/RFC822/SMTP,
-			  A=IPC [127.0.0.1] $h
-
-  (i.e., where $h is the port number instead of the host name) the
-  connection caching code will break because it won't notice that
-  two messages addressed to different ports should use different
-  connections.
-
-* ESMTP SIZE underestimates the size of a message
-
-  Sendmail makes no allowance for headers that it adds, nor does it
-  account for the SMTP on-the-wire \r\n expansion.  It probably doesn't
-  allow for 8->7 bit MIME conversions either.
-
-* Client ignores SIZE parameter.
-
-  When sendmail acts as client and the server specifies a limit
-  for the mail size, sendmail will ignore this and try to send the
-  mail anyway.  The server will usually reject the MAIL command
-  which specifies the size of the message and hence this problem
-  is not significant.
-
-* Paths to programs being executed and the mode of program files are
-  not checked.  Essentially, the RunProgramInUnsafeDirPath and
-  RunWritableProgram bits in the DontBlameSendmail option are always
-  set.  This is not a problem if your system is well managed (that is,
-  if binaries and system directories are mode 755 instead of something
-  foolish like 777).
-
-* 8-bit data in GECOS field
-
-  If the GECOS (personal name) information in the passwd file contains
-  8-bit characters, those characters can be included in the message
-  header, which can cause problems when sending SMTP to hosts that
-  only accept 7-bit characters.
-
-* 8->7 bit MIME conversion
-
-  When sendmail is doing 8->7 bit MIME conversions, and the message
-  contains certain MIME body types that cannot be converted to 7-bit,
-  sendmail will pass the message as 8-bit.
-
-* 7->8 bit MIME conversion
-
-  If a message that is encoded as 7-bit MIME is converted to 8-bit and
-  that message when decoded is illegal (e.g., because of long lines or
-  illegal characters), sendmail can produce an illegal message.
-
-* MIME encoded full name phrases in the From: header
-
-  If a full name phrase includes characters from MustQuoteChars, sendmail
-  will quote the entire full name phrase.  If MustQuoteChars includes
-  characters which are not special characters according to STD 11 (RFC
-  822), this quotation can interfere with MIME encoded full name phrases.
-  By default, sendmail includes the single quote character (') in
-  MustQuoteChars even though it is not listed as a special character in
-  STD 11.
-
-* bestmx map with -z flag truncates the list of MX hosts
-
-  A bestmx map configured with the -z flag will truncate the list
-  of MX hosts.  This prevents creation of strings which are too
-  long for ruleset parsing.  This can have an adverse effect on the
-  relay_based_on_MX feature.
-
-* Saving to ~sender/dead.letter fails if su'ed to root
-
-  If ErrorMode is set to print and an error in sending mail occurs,
-  the normal action is to print a message to the screen and append
-  the message to a dead.letter file in the sender's home directory.
-  In the case where the sender is using su to act as root, the file
-  safety checks prevent sendmail from saving the dead.letter file
-  because the sender's uid and the current real uid do not match.
-
-* Berkeley DB 2.X race condition with fcntl() locking
-
-  There is a race condition for Berkeley DB 2.X databases on
-  operating systems which use fcntl() style locking, such as
-  Solaris.  Sendmail locks the map before calling db_open() to
-  prevent others from modifying the map while it is being opened.
-  Unfortunately, Berkeley DB opens the map, closes it, and then
-  reopens it.  fcntl() locking drops the lock when any file
-  descriptor pointing to the file is closed, even if it is a
-  different file descriptor than the one used to initially lock
-  the file.  As a result there is a possibility that entries in a
-  map might not be found during a map rebuild.  As a workaround,
-  you can use makemap to build a map with a new name and then
-  "mv" the new db file to replace the old one.
-
-  Sleepycat Software has added code to avoid this race condition to
-  Berkeley DB versions after 2.7.5.
-
-* File open timeouts not available on hard mounted NFS file systems
-
-  Since SIGALRM does not interrupt an RPC call for hard mounted
-  NFS file systems, it is impossible to implement a timeout on a file
-  open operation.  Therefore, while the NFS server is not responding,
-  attempts to open a file on that server will hang.  Systems with
-  local mail delivery and NFS hard mounted home directories should be
-  avoided, as attempts to open the forward files could hang.
-
-* Race condition for delivery to set-user-ID files
-
-  Sendmail will deliver to a fail if the file is owned by the DefaultUser
-  or has the set-user-ID bit set.  Unfortunately, some systems clear that bit
-  when a file is modified.  Sendmail compensates by resetting the file mode
-  back to it's original settings.  Unfortunately, there's still a
-  permission failure race as sendmail checks the permissions before locking
-  the file.  This is unavoidable as sendmail must verify the file is safe
-  to open before opening it.  A file can not be locked until it is open.
-
-* MAIL_HUB always takes precedence over LOCAL_RELAY
-
-  Despite the information in the documentation, MAIL_HUB ($H) will always
-  be used if set instead of LOCAL_RELAY ($R).  This will be fixed in a
-  future version.

-
-+-----------------------+
-| DIRECTORY PERMISSIONS |
-+-----------------------+
-
-Sendmail often gets blamed for many problems that are actually the
-result of other problems, such as overly permissive modes on directories.
-For this reason, sendmail checks the modes on system directories and
-files to determine if they can be trusted.  For sendmail to run without
-complaining, you MUST execute the following command:
-
-	chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
-	chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
-
-You will probably have to tweak this for your environment (for example,
-some systems put the spool directory into /usr/spool instead of
-/var/spool).  If you set the RunAsUser option in your sendmail.cf, the
-/var/spool/mqueue directory will have to be owned by the RunAsUser user.
-As a general rule, after you have compiled sendmail, run the command
-
-	sendmail -v -bi
-
-to initialize the alias database.  If it gives messages such as
-
-	WARNING: writable directory /etc
-	WARNING: writable directory /var/spool/mqueue
-
-then the directories listed have inappropriate write permissions and
-should be secured to avoid various possible security attacks.
-
-Beginning with sendmail 8.9, these checks have become more strict to
-prevent users from being able to access files they would normally not
-be able to read.  In particular, .forward and :include: files in unsafe
-directory paths (directory paths which are group or world writable) will
-no longer be allowed.  This would mean that if user joe's home directory
-was writable by group staff, sendmail would not use his .forward file.
-This behavior can be altered, at the expense of system security, by
-setting the DontBlameSendmail option.  For example, to allow .forward
-files in group writable directories:
-
-	O DontBlameSendmail=forwardfileingroupwritabledirpath
-
-Or to allow them in both group and world writable directories:
-
-	O DontBlameSendmail=forwardfileinunsafedirpath
-
-Items from these unsafe .forward and :include: files will be marked
-as unsafe addresses -- the items can not be deliveries to files or
-programs.  This behavior can also be altered via DontBlameSendmail:
-
-	O DontBlameSendmail=forwardfileinunsafedirpath,
-		forwardfileinunsafedirpathsafe
-
-The first flag allows the .forward file to be read, the second allows
-the items in the file to be marked as safe for file and program
-delivery.
-
-Other files affected by this strengthened security include class
-files (i.e., Fw /etc/mail/local-host-names), persistent host status files,
-and the files specified by the ErrorHeader and HelpFile options.  Similar
-DontBlameSendmail flags are available for the class, ErrorHeader, and
-HelpFile files.
-
-If you have an unsafe configuration of .forward and :include:
-files, you can make it safe by finding all such files, and doing
-a "chmod go-w $FILE" on each.  Also, do a "chmod go-w $DIR" for
-each directory in the file's path.
-
-
-+--------------------------+
-| FILE AND MAP PERMISSIONS |
-+--------------------------+
-
-Any application which uses either flock() or fcntl() style locking or
-other APIs that use one of these locking methods (such as open() with
-O_EXLOCK and O_SHLOCK) on files readable by other local untrusted users
-may be susceptible to local denial of service attacks.
-
-File locking is used throughout sendmail for a variety of files
-including aliases, maps, statistics, and the pid file.  Any user who
-can open one of these files can prevent sendmail or it's associated
-utilities, e.g., makemap or newaliases, from operating properly.  This
-can also affect sendmail's ability to update status files such as
-statistics files.  For system which use flock() for file locking, a
-user's ability to obtain an exclusive lock prevents other sendmail
-processes from reading certain files such as alias or map databases.
-
-A workaround for this problem is to protect all sendmail files such
-that they can't be opened by untrusted users.  As long as users can
-not open a file, they can not lock it.  Since queue files should
-already have restricted permissions, the only files that need
-adjustment are alias, map, statistics, and pid files.  These files
-should be owned by root or the trusted user specified in the
-TrustedUser option.  Changing the permissions to be only readable and
-writable by that user is sufficient to avoid the denial of service.
-For example, depending on the paths you use, these commands would be
-used:
-
-	chmod 0640 /etc/mail/aliases /etc/mail/aliases.{db,pag,dir}
-	chmod 0640 /etc/mail/*.{db,pag,dir}
-	chmod 0640 /etc/mail/statistics /var/log/sendmail.st
-	chmod 0600 /var/run/sendmail.pid /etc/mail/sendmail.pid
-
-If the permissions 0640 are used, be sure that only trusted users belong
-to the group assigned to those files.  Otherwise, files should not even
-be group readable.  As of sendmail 8.12.4, the permissions shown above
-are the default permissions for newly created files.
-
-Note that the denial of service on the plain text aliases file
-(/etc/mail/aliases) only prevents newaliases from rebuilding the
-aliases file.  The same is true for the database files on systems which
-use fcntl() style locking.  Since it does not interfere with normal
-operations, sites may chose to leave these files readable.  Also, it is
-not necessary to protect the text files associated with map databases
-as makemap does not lock those files.

-
-There are other files you should read.  Rooted in this directory are:
-
-  FAQ
-	The FAQ (frequently answered questions) is no longer maintained
-	with the sendmail release.  It is available at
-	http://www.sendmail.org/faq/ .  The file FAQ is a reminder of
-	this and a pointer to the web page.
-  INSTALL
-	Installation instructions for building and installing sendmail.
-  KNOWNBUGS
-	Known bugs in the current release.
-  RELEASE_NOTES
-	A detailed description of the changes in each version.  This
-	is quite long, but informative.
-  sendmail/README
-	Details on compiling and installing sendmail.
-  cf/README
-	Details on configuring sendmail.
-  doc/op/op.me
-	The sendmail Installation & Operations Guide.  In addition
-	to the shipped PostScript version, plain text and PDF versions
-	can be generating using (assuming the required conversion software
-	is installed on your system, see doc/op/Makefile):
-
-	cd doc/op && make op.txt op.pdf
-
-	Be warned: on some systems calling make in doc/op/ will cause
-	errors due to nroff/groff problems.  Known problems are:
-	- running this off on systems with an old version of -me, you
-	need to add the following macro to the macros:
-
-		.de sm
-		\s-1\\$1\\s0\\$2
-		..
-
-	This sets a word in a smaller pointsize.
-
-	- with new groff versions (1.18 seems affected)
-
-	GROFF_NO_SGR=1
-
-	needs to be set, e.g., in doc/op/Makefile:
-
-	ROFF_CMD=	GROFF_NO_SGR=1 groff

-| DATABASE ROUTINES |
-+-------------------+
-
-IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE:  ****  DO NOT  ****
-use the version that was on the Net2 tape -- it has a number of
-nefarious bugs that were bad enough when I got them; you shouldn't have
-to go through the same thing.  Instead, get a new version via the web at
-http://www.sleepycat.com/.  This software is highly recommended; it gets
-rid of several stupid limits, it's much faster, and the interface is
-nicer to animals and plants.  If the Berkeley DB include files
-are installed in a location other than those which your compiler searches,
-you will need to provide that directory when building:
-
-	Build -I/path/to/include/directory
-
-If you are using Berkeley DB versions 1.85 or 1.86, you are *strongly*
-urged to upgrade to DB version 2 or later, available from
-http://www.sleepycat.com/.  Berkeley DB versions 1.85 and 1.86 are known to
-be broken in various nasty ways (see http://www.sleepycat.com/db.185.html),
-and can cause sendmail to dump core.  In addition, the newest versions of
-gcc and the Solaris compilers perform optimizations in those versions that
-may cause fairly random core dumps.
-
-If you have no choice but to use Berkeley DB 1.85 or 1.86, and you are
-using both Berkeley DB and files in the UNIX ndbm format, remove ndbm.h
-and ndbm.o from the DB library after building it.  You should also apply
-all of the patches for DB 1.85 and 1.86 found at the Sleepycat web site
-(see http://www.sleepycat.com/db.185.html), as they fix some of the known
-problems.
-
-If you are using a version of Berkeley DB 2 previous to 2.3.15, and you
-are using both Berkeley DB and files in the UNIX ndbm format, remove dbm.o
-from the DB library after building it.  No other changes are necessary.
-
-If you are using Berkeley DB version 2.3.15 or greater, no changes are
-necessary.
-
-The underlying database file formats changed between Berkeley DB versions
-1.85 and 1.86, again between DB 1.86 and version 2.0, and finally between
-DB 2.X and 3.X.  If you are upgrading from one of those versions, you must
-recreate your database file(s).  Do this by rebuilding all maps with
-makemap and rebuilding the alias file with newaliases.
-
-
-+--------------------+
-| HOST NAME SERVICES |
-+--------------------+
-
-If you are using NIS or /etc/hosts, it is critical that you
-list the long (fully qualified) name somewhere (preferably first) in
-the /etc/hosts file used to build the NIS database.  For example, the
-line should read
-
-	128.32.149.68   mastodon.CS.Berkeley.EDU mastodon
-
-**** NOT ****
-
-	128.32.149.68   mastodon
-
-If you do not include the long name, sendmail will complain loudly
-about ``unable to qualify my own domain name (mastodon) -- using
-short name'' and conclude that your canonical name is the short
-version and use that in messages.  The name "mastodon" doesn't mean
-much outside of Berkeley, and so this creates incorrect and unreplyable
-messages.
-
-
-+-------------+
-| USE WITH MH |
-+-------------+
-
-This version of sendmail notices and reports certain kinds of SMTP
-protocol violations that were ignored by older versions.  If you
-are running MH you may wish to install the patch in contrib/mh.patch
-that will prevent these warning reports.  This patch also works
-with the old version of sendmail, so it's safe to go ahead and
-install it.
-
-
-+----------------+
-| USE WITH IDENT |
-+----------------+
-
-Sendmail 8 supports the IDENT protocol, as defined by RFC 1413.
-Note that the RFC states a client should wait at least 30 seconds
-for a response.  As of 8.10.0, the default Timeout.ident is 5 seconds
-as many sites have adopted the practice of dropping IDENT queries.
-This has lead to delays processing mail.
-
-No ident server is included with this distribution.  It is available
-from:
-
-  ftp://ftp.lysator.liu.se/pub/ident/servers/
-  http://sf.www.lysator.liu.se/~pen/pidentd/
-
-+-------------------------+
-| INTEROPERATION PROBLEMS |
-+-------------------------+
-
-Microsoft Exchange Server 5.0
-	We have had a report that ``about 7% of messages from Sendmail
-	to Exchange were not being delivered with status messages of
-	"connection reset" and "I/O error".''  Upgrading Exchange from
-	Version 5.0 to Version 5.5 Service Pack 2 solved this problem.
-
-CommuniGate Pro
-	CommuniGate Pro 3.2.4 does not accept the AUTH= -parameter on
-	the MAIL FROM command if the client is not authenticated.  Use
-
-		define(`confAUTH_OPTIONS', `A')
-
-	in .mc file if you have compiled sendmail with Cyrus SASL
-	and you communicate with CommuniGate Pro servers.
-
-+---------------------+
-| DIRECTORY STRUCTURE |
-+---------------------+
-
-The structure of this directory tree is:
-
-cf		Source for sendmail configuration files.  These are
-		different than what you've seen before.  They are a
-		fairly dramatic rewrite, requiring the new sendmail
-		(since they use new features).
-contrib		Some contributed tools to help with sendmail.  THESE
-		ARE NOT SUPPORTED by sendmail -- contact the original
-		authors if you have problems.  (This directory is not
-		on the 4.4BSD tape.)
-devtools	Build environment.  See devtools/README.
-doc		Documentation.  If you are getting source, read
-		op.me -- it's long, but worth it.
-editmap		A program to edit and query maps that have been created
-		with makemap, e.g., adding and deleting entries.
-include		Include files used by multiple programs in the distribution.
-libsmdb		sendmail database library with support for Berkeley DB 1.X,
-		Berkeley DB 2.X, Berkeley DB 3.X, and NDBM.
-libsmutil	sendmail utility library with functions used by different
-		programs.
-mail.local	The source for the local delivery agent used for 4.4BSD.
-		THIS IS NOT PART OF SENDMAIL! and may not compile
-		everywhere, since it depends on some 4.4-isms.  Warning:
-		it does mailbox locking differently than other systems.
-mailstats	Statistics printing program.
-makemap		A program that creates the keyed maps used by the $( ... $)
-		construct in sendmail.  It is primitive but effective.
-		It takes a very simple input format, so you will probably
-		expect to preprocess must human-convenient formats
-		using sed scripts before this program will like them.
-		But it should be functionally complete.
-praliases	A program to print the DBM or NEWDB version of the
-		aliases file.
-rmail		Source for rmail(8).  This is used as a delivery
-		agent for for UUCP, and could presumably be used by
-		other non-socket oriented mailers.  Older versions of
-		rmail are probably deficient.  RMAIL IS NOT PART OF
-		SENDMAIL!!!  The 4.4BSD source is included for you to
-		look at or try to port to your system.  There is no
-		guarantee it will even compile on your operating system.
-smrsh		The "sendmail restricted shell", which can be used as
-		a replacement for /bin/sh in the prog mailer to provide
-		increased security control.  NOT PART OF SENDMAIL!
-sendmail	Source for the sendmail program itself.
-test		Some test scripts (currently only for compilation aids).
-vacation	Source for the vacation program.  NOT PART OF SENDMAIL!

-			SENDMAIL RELEASE NOTES
-      $Id: RELEASE_NOTES,v 8.1909 2007/10/31 16:04:13 ca Exp $
-
-
-This listing shows the version of the sendmail binary, the version
-of the sendmail configuration files, the date of release, and a
-summary of the changes in that release.
-
-8.14.2/8.14.2	2007/11/01
-	If a message was queued and it contained 8 bit characters in
-		a From: or To: header, then those characters could be
-		"mistaken" for internal control characters during a queue
-		run and trigger various consistency checks.  Problem
-		noted by Neil Rickert of Northern Illinois University.
-	If MaxMimeHeaderLength is set to a value greater than 0 (which
-		it is by default) then even if the Linelimit parameter
-		is 0, sendmail corrupted in the non-transfer-encoding
-		case every MAXLINE-1 characters.  Patch from John Gardiner
-		Myers of Proofpoint.
-	Setting the suboption DeliveryMode for DaemonPortOptions did not
-		work in earlier 8.14 versions.
-	Note: DeliveryMode=interactive is silently converted to
-		background if a milter can reject or delete a recipient.
-		Prior to 8.14 this happened only if milter could delete
-		recipients.
-	ClientRate should trigger when the limit was exceeded (as
-		documented), not when it was reached.  Patch from 
-		John Beck of Sun Microsystems.
-	Force a queue run for -qGqueuegroup even if no runners are
-		specified (R=0) and forking (F=f) is requested.
-	When multiple results are requested for a DNS map lookup
-		(-z and -Z), return only those that are relevant for
-		the query (not also those in the "additional section".)
-	If the message transfer time to sendmail (when acting as server)
-		exceeds Timeout.queuewarn or Timeout.queuereturn and
-		the message is refused (by a milter), sendmail previously
-		created a delivery status notification (DSN).  Patch
-		from Doug Heath of The Hertz Corporation.
-	A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires
-		the MTA to deal with some input (i.e., "=") itself.
-		Problem noted by Eliot Lear.
-	sendmail counted a delivery as successful if PIPELINING is
-		compiled in but not offered by the server and the
-		delivery failed temporarily.  Patch from Werner Wiethege.
-	If getting the result of an LDAP query times out then close the
-		map so it will be reopened on the next lookup.  This
-		should help "failover" configurations that specify more
-		than one LDAP server.
-	If check_compat returns $#discard then a "savemail panic" could
-		be triggered under some circumstances (e.g., requiring
-		a system which does not have the compile time flag
-		HASFLOCK set). Based on patch by Motonori Nakamura
-		of National Institute of Informatics, Japan.
-	If a milter rejected a recipient, the count for nrcpts= in the
-		logfile entry might have been wrong.  Problem found by
-		Petra Humann of TU Dresden.
-	If a milter invoked smfi_chgfrom() where ESMTP arguments are not
-		NULL, the message body was lost.  Patch from Motonori
-		Nakamura of National Institute of Informatics, Japan.
-	sendmail(8) had a bogus space in -qGname.  Patch from Peng Haitao.
-	CONTRIB: buildvirtuser: Preserve ownership and permissions when
-		replacing files.
-	CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when
-		reading the /etc/mail/virtusers/ directory.
-	CONTRIB: buildvirtuser: Emit warnings instead of exiting where
-		appropriate.
-	LIBMILTER: Fix ABI backwards compatibility so milters compiled
-		against an older libmilter.so shared library can use an
-		8.14 libmilter.so shared library.
-	LIBMILTER: smfi_version() did not properly extract the patchlevel
-		from the version number, however, the returned value was
-		correct for the current libmilter version.
-
-8.14.1/8.14.1	2007/04/03
-	Even though a milter rejects a recipient the MTA will still keep
-		it in its list of recipients and deliver to it if the
-		transaction is accepted. This is a regression introduced
-		in 8.14.0 due to the change for SMFIP_RCPT_REJ.  Bug
-		found by Andy Fiddaman.
-	The new DaemonPortOptions which begin with a lower case character
-		could not be set in 8.14.0.
-	If a server shut down the connection in response to a STARTTLS
-		command, sendmail would log a misleading error message
-		due to an internal inconsistency.  Problem found by
-		Werner Wiethege.
-	Document how some sendmail.cf options change the behavior of mailq.
-		Noted by Paul Menchini of the North Carolina School of
-		Science and Mathematics.
-	CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce.
-	CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition
-		of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE
-		m4 options for setting MaxNOOPCommands and
-		SharedMemoryKeyFile.
-	CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4
-		options for setting Milter.macros.eoh and Milter.macros.data.
-	CONTRIB: Use flock() and fcntl() in qtool.pl if necessary.
-		Patch from Daniel Carroll of Mesa State College.
-	LIBMILTER: Make sure an unknown command does not affect the
-		currently available macros.  Problem found by Andy Fiddaman.
-	LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option
-		negotiation.  Problem reported by Bryan Costales.
-	LIBMILTER: Fix several minor errors in the documentation.
-		Patches from Bryan Costales.
-	PORTABILITY FIXES:
-		AIX 5.{1,2}: libsm/util.c failed to compile due to
-			redefinition of several macros, e.g., SIG_ERR.
-			Patch from Jim Pirzyk with assistance by Bob
-			Booth, University of Illinois at Urbana-Champaign.
-		Add support for QNX.6.  Patch from Sean Boudreau of QNX
-			Software Systems.
-	New Files:
-		devtools/M4/depend/QNX6.m4
-		devtools/OS/QNX.6.x
-		include/sm/os/sm_os_qnx.h
-
-	New Files added in 8.14.0, but not shown in the release notes entry:
-		libmilter/docs/smfi_chgfrom.html
-		libmilter/docs/smfi_version.html
-
-8.14.0/8.14.0	2007/01/31
-	Header field values are now 8 bit clean.  Notes:
-		- header field names are still restricted to 7 bit.
-		- RFC 2822 allows only 7 bit (US-ASCII) characters in
-		  headers.
-	Preserve spaces after the colon in a header.  Previously, any
-		number of spaces after the colon would be changed to
-		exactly one space.
-	In some cases of deeply nested aliases/forwarding, mail can
-		be silently lost.  Moreover, the MaxAliasRecursion
-		limit may be reached too early, e.g., the counter
-		may be off by a factor of 4 in case of a sequence of
-		.forward files that refer to others.  Patch from
-		Motonori Nakamura of Kyoto University.
-	Fix a regression in 8.13.8: if InputMailFilters is set then
-		"sendmail -bs" can trigger an assertion because the
-		hostname of the client is undefined.  It is now set
-		to "localhost" for the xxfi_connect() callback.
-	Avoid referencing a freed variable during cleanup when terminating.
-		Problem reported and diagnosed by Joe Maimon.
-	New option HeloName to set the name for the HELO/EHLO command.
-		Patch from Nik Clayton.
-	New option SoftBounce to issue temporary errors (4xy) instead of
-		permanent errors (5xy).  This can be useful for testing.
-	New suboptions for DaemonPortOptions to set them individually
-		per daemon socket:
-			DeliveryMode	DeliveryMode
-			refuseLA	RefuseLA
-			delayLA		DelayLA
-			queueLA		QueueLA
-			children	MaxDaemonChildren
-	New option -K for LDAP maps to replace %1 through %9 in the
-		lookup key with the LDAP escaped contents of the
-		arguments specified in the map lookup.  Loosely based
-		on patch from Wolfgang Hottgenroth.
-	Log the time after which a greet_pause delay triggered.  Patch
-		from Nik Clayton.
-	If a client is rejected via TCP wrapper or some other check
-		performed by validate_connection() (in conf.c) then do
-		not also invoke greet_pause.  Problem noted by Jim Pirzyk
-		of the University of Illinois at Urbana-Champaign.
-	If a client terminates the SMTP connection during a pause
-		introduced by greet_pause, then a misleading message
-		was logged previously.  Problem noted by Vernon Schryver
-		et.al., patch from Matej Vela.
-	New command "mstat" for control socket to provide "machine
-		readable" status.
-	New named config file rule check_eom which is called at the end
-		of a message, its parameter is the size of the message.
-	If the macro {addr_type} indicates that the current address
-		is a header address it also distinguishes between
-		recipient and sender addresses (as it is done for
-		envelope addresses).
-	When a macro is set in check_relay, then its value is accessible
-		by all transactions in the same SMTP session.
-	Increase size of key for ldap lookups to 1024 (MAXKEY).
-	New option MaxNOOPCommands to override default of 20 for the
-		number of "useless" commands before the SMTP server will
-		slow down responding.
-	New option SharedMemoryKeyFile: if shared memory support is
-		enabled, the MTA can be asked to select a shared memory
-		key itself by setting SharedMemoryKey to -1 and specifying
-		a file where to store the selected key.
-	Try to deal with open HTTP proxies that are used to send spam
-		by recognizing some commands from them. If the first command
-		from the client is GET, POST, CONNECT, or USER, then the
-		connection is terminated immediately.
-	New PrivacyOptions noactualrecipient to avoid putting
-		X-Actual-Recipient lines in DSNs revealing the actual
-		account that addresses map to.  Patch from Dan Harkless.
-	New options B, z, and Z for DNS maps:
-		-B: specify a domain that is always appended to queries.
-		-z: specify the delimiter at which to cut off the result of
-			a query if it is too long.
-		-Z: specify the maximum number of entries to be concatenated
-			to form the result of a lookup.
-	New target "check" in the Makefile of libsm: instead of running tests
-		implicitly while building libsm, they must be explicitly
-		started by using "make check".
-	Fixed some inconsistent checks for NULL pointers that have been
-		reported by the SATURN tool which has been developed by
-		Isil Dillig and Thomas Dillig of Stanford University.
-	Fix a potential race condition caused by a signal handler for
-		terminated child processes.  Problem noted by David F. Skoll.
-	When a milter deleted a recipient, that recipient could cause a
-		queue group selection. This has been disabled as it was not
-		intended.
-	New operator 'r' for the arith map to return a random number.
-		Patch from Motonori Nakamura of Kyoto University.
-	New compile time option MILTER_NO_NAGLE to turn off the Nagle
-		algorithm for communication with libmilter ("cork" on Linux),
-		which may improve the communication performance on some
-		operating systems.  Patch from John Gardiner Myers of
-		Proofpoint.
-	If sendmail received input that contained a CR without subsequent LF
-		(thus violating RFC 2821 (2.3.7)), it could previously
-		generate an additional blank line in the output as the last
-		line.
-	Restarting persistent queue runners by sending a HUP signal to
-		the "queue control process" (QCP) works now.
-	Increase the length of an input line to 12288 to deal with
-		really long lines during SMTP AUTH negotiations.
-		Problem noted by Werner Wiethege.
-	If ARPANET mode (-ba) was selected STARTTLS would fail (due to
-		a missing initialization call for that case).  Problem
-		noted by Neil Rickert of Northern Illinois University.
-	If sendmail is linked against a library that initializes Cyrus-SASL
-		before sendmail did it (such as libnss-ldap), then SMTP AUTH
-		could fail for the sendmail client.  A patch by Moritz Both
-		works around the API design flaw of Cyrus-SASLv2.
-	CONFIG: Make it possible to unset the StatusFile option by
-		undefining STATUS_FILE.  By not setting StatusFile,
-		the MTA will not attempt to open a statistics file on
-		each delivery.
-	CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP
-		clients whose IP address does not have proper reverse DNS.
-		Contributed by Neil Rickert of Northern Illinois University
-		and John Beck of Sun Microsystems.
-	CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP
-		clients which provide a HELO/EHLO argument which is either
-		unqualified, or is one of our own names (i.e., the server
-		name instead of the client name).  Contributed by Neil
-		Rickert of Northern Illinois University and John Beck of
-		Sun Microsystems.
-	CONFIG: New FEATURE(`badmx') to reject envelope sender addresses
-		(MAIL) whose domain part resolves to a "bad" MX record.
-		Based on contribution from William Dell Wisner.
-	CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override
-		the maximum line length of the smtp mailers.
-	CONFIG: New option `relaytofulladdress' for FEATURE(`access_db')
-		to allow entries in the access map to be of the form
-			To:user@example.com	RELAY
-	CONFIG: New subsuboptions eoh and data to specify the list of
-		macros a milter should receive at those stages in the
-		SMTP dialogue.
-	CONFIG: New option confHELO_NAME for HeloName to set the name
-		for the HELO/EHLO command.
-	CONFIG: dnsbl and enhdnsbl can now also discard or quarantine
-		messages by using those values as second argument.
-		Patches from Nelson Fung.
-	CONTRIB: cidrexpand uses a hash symbol as comment character and
-		ignores everything after it unless it is in quotes or
-		preceeded by a backslash.
-	DEVTOOLS: New macro confMKDIR: if set to a program that creates
-		directories, then it used for "make install" to create
-		the required installation directories.
-	DEVTOOLS: New macro confCCLINK to specify the linker to use for
-		executables (defaults to confCC).
-	LIBMILTER: A new version of the milter API has been created that
-		has several changes which are listed below and documented
-		in the webpages reachable via libmilter/docs/index.html.
-	LIBMILTER: The meaning of the version macro SMFI_VERSION has been
-		changed.  It now refers only to the version of libmilter,
-		not to the protocol version (which is used only internally,
-		it is not user/milter-programmer visible).  Additionally,
-		a version function smfi_version() has been introduced such
-		that a milter program can check the libmilter version also
-		at runtime which is useful if a shared library is used.
-	LIBMILTER: A new callback xxfi_negotiate() can be used to
-		dynamically (i.e., at runtime) determine the available
-		protocol actions and features of the MTA and also to
-		specify which of these a milter wants to use.  This allows
-		for more flexibility than hardcoding these flags in the
-		xxfi_flags field of the smfiDesc structure.
-	LIBMILTER: A new callback xxfi_data() is available so milters
-		can act on the DATA command.
-	LIBMILTER: A new callback xxfi_unknown() is available so milters
-		can receive also unknown SMTP commands.
-	LIBMILTER: A new return code SMFIS_NOREPLY has been added which
-		can be used by the xxfi_header() callback provided the
-		milter requested the SMFIP_NOHREPL protocol action.
-	LIBMILTER: The new return code SMFIS_SKIP can be used in the
-		xxfi_body() callback to skip over further body chunks
-		and directly advance to the xxfi_eom() callback.  This
-		is useful if a milter can make a decision based on the
-		body chunks it already received without reading the entire
-		rest of the body and the milter wants to invoke functions
-		that are only available from the xxfi_eom() callback.
-	LIBMILTER: A new function smfi_addrcpt_par() can be used to add
-		new recipients including ESMTP parameters.
-	LIBMILTER: A new function smfi_chgfrom() can be used to change the
-		envelope sender including ESMTP parameters.
-	LIBMILTER: A milter can now request to be informed about rejected
-		recipients (RCPT) too.  This requires to set the protocol
-		flag SMFIP_RCPT_REJ during option negotiation.  Whether
-		a RCPT has been rejected can be checked by comparing the
-		value of the macro {rcpt_mailer} with "error".
-	LIBMILTER: A milter can now override the list of macros that it
-		wants to receive from the MTA for each protocol step
-		by invoking the function smfi_setsymlist() during option
-		negotiation.
-	LIBMILTER: A milter can receive header field values with all
-		leading spaces by requesting the SMFIP_HDR_LEADSPC
-		protocol action.  Also, if the flag is set then the MTA
-		does not add a leading space to headers that are added,
-		inserted, or replaced.
-	LIBMILTER: If a milter sets the reply code to "421" for the HELO
-		callback, the SMTP server will terminate the SMTP session
-		with that error to match the behavior of all other callbacks.

-8.13.8/8.13.8	2006/08/09
-	Fix a regression in 8.13.7: if shared memory is activated, then
-		the server can erroneously report that there is
-		insufficient disk space.  Additionally make sure that
-		an internal variable is set properly to avoid those
-		misleading errors.  Based on patch from Steve Hubert
-		of University of Washington.
-	Fix a regression in 8.13.7: the PidFile could be removed after
-		the process that forks the daemon exited, i.e., if
-		sendmail -bd is invoked.  Problem reported by Kan Sasaki
-		of Fusion Communications Corp. and Werner Wiethege.
-	Avoid opening qf files if QueueSortOrder is "none".  Patch from
-		David F. Skoll.
-	Avoid a crash when finishing due to referencing a freed variable.
-		Problem reported and diagnosed by Moritz Jodeit.
-	CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4
-		range (0..255).
-	LIBMILTER: The "hostname" argument of the xxfi_connect() callback
-		previously was the equivalent of {client_ptr}.  However,
-		this did not match the documentation of the function, hence
-		it has been changed to {client_name}.  See doc/op/op.*
-		about these macros.
-
-8.13.7/8.13.7	2006/06/14
-	A malformed MIME structure with many parts can cause sendmail to
-		crash while trying to send a mail due to a stack overflow,
-		e.g., if the stack size is limited (ulimit -s).  This
-		happens because the recursion of the function mime8to7()
-		was not restricted.  The function is called for MIME 8 to
-		7 bit conversion and also to enforce MaxMimeHeaderLength.
-		To work around this problem, recursive calls are limited to
-		a depth of MAXMIMENESTING (20); message content after this
-		limit is treated as opaque and is not checked further.
-		Problem noted by Frank Sheiness.
-	The changes to the I/O layer in 8.13.6 caused a regression for
-		SASL mechanisms that use the security layer, e.g.,
-		DIGEST-MD5.  Problem noted by Robert Stampfli.
-	If a timeout occurs while reading a message (during the DATA phase)
-		a df file might have been left behind in the queue.
-		This was another side effect of the changes to the I/O
-		layer made in 8.13.6.
-	Several minor problems have been fixed that were found by a
-		Coverity scan of sendmail 8 as part of the NetBSD
-		distribution. See http://scan.coverity.com/
-		Note: the scan generated also a lot of "false positives",
-		e.g., "error" reports about situations that cannot happen.
-		Most of those code places are marked with lint(1) comments
-		like NOTREACHED, but Coverity does not understand those.
-		Hence an explicit assertion has been added in some cases
-		to avoid those false positives.
-	If the start of the sendmail daemon fails due to a configuration
-		error then in some cases shared memory segments or pid
-		files were not removed.
-	If DSN support is disabled via access_db, then related ESMTP
-		parameters for MAIL and RCPT should be rejected.  Problem
-		reported by Akihiro Sagawa.
-	Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding
-		bug work-around.  Hence if sendmail is linked against
-		either of these versions and compression is available,
-		the padding bug work-around is turned off.  Based on
-		patch from Victor Duchovni of Morgan Stanley.
-	CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used
-		blackholes.mail-abuse.org as default domain for lookups,
-		however, that list is no longer available.  To avoid
-		further problems, no default value is available anymore,
-		but an argument must be specified.
-	Portability:
-		Fix compilation on OSF/1 for sfsasl.c.  Patch from
-		Pieter Bowman of the University of Utah.
-
-8.13.6/8.13.6	2006/03/22
-	SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server
-		and client side of sendmail with timeouts in the libsm I/O
-		layer and fix problems in that code.  Also fix handling of
-		a buffer in sm_syslog() which could have been used as an
-		attack vector to exploit the unsafe handling of
-		setjmp(3)/longjmp(3) in combination with signals.
-		Problem detected by Mark Dowd of ISS X-Force.
-	Handle theoretical integer overflows that could triggered if
-		the server accepted headers larger than the maximum
-		(signed) integer value.  This is prevented in the default
-		configuration by restricting the size of a header, and on
-		most machines memory allocations would fail before reaching
-		those values.  Problems found by Phil Brass of ISS.
-	If a server returns 421 for an RSET command when trying to start
-		another transaction in a session while sending mail, do
-		not trigger an internal consistency check.  Problem found
-		by Allan E Johannesen of Worcester Polytechnic Institute.
-	If a server returns a 5xy error code (other than 501) in response
-		to a STARTTLS command despite the fact that it advertised
-		STARTTLS and that the code is not valid according to RFC
-		2487 treat it nevertheless as a permanent failure instead
-		of a protocol error (which has been changed to a
-		temporary error in 8.13.5).  Problem reported by Jeff
-		A. Earickson of Colby College.
-	Clear SMTP state after a HELO/EHLO command.  Patch from John
-		Myers of Proofpoint.
-	Observe MinQueueAge option when gathering entries from the queue
-		for sorting etc instead of waiting until the entries are
-		processed.  Patch from Brian Fundakowski Feldman.
-	Set up TLS session cache to properly handle clients that try to
-		resume a stored TLS session.
-	Properly count the number of (direct) child processes such that
-		a configured value (MaxDaemonChildren) is not exceeded.
-		Based on patch from Attila Bruncsak.
-	LIBMILTER: Remove superfluous backslash in macro definition
-		(libmilter.h).  Based on patch from Mike Kupfer of
-		Sun Microsystems.
-	LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets.
-		This generates an error message from libmilter on
-		Solaris, though other systems appear to just discard the
-		request silently.
-	LIBMILTER: Deal with sigwait(2) implementations that return
-		-1 and set errno instead of returning an error code
-		directly.  Patch from Chris Adams of HiWAAY Informations
-		Services.
-	Portability:
-		Fix compilation checks for closefrom(3) and statvfs(2)
-		in NetBSD.  Problem noted by S. Moonesamy, patch from
-		Andrew Brown.
-
-8.13.5/8.13.5	2005/09/16
-	Store the filesystem identifier of the df/ subdirectory (if it
-		exists) in an internal structure instead of the base
-		directory.  This structure is used decide whether there
-		is enough free disk space when selecting a queue, hence
-		without this change queue selection could fail if a df/
-		subdirectory exists and is on a different filesystem
-		than the base directory.
-	Use the queue index of the df file (instead of the qf file) for
-		checking whether a link(2) operation can be used to split
-		an envelope across queue groups.  Problem found by
-		Werner Wiethege.
-	If the list of items in the queue is larger than the maximum
-		number of items to process, sort the queue first and
-		then cut the list off instead of the other way around.
-		Patch from Matej Vela of Rudjer Boskovic Institute.
-	Fix helpfile to show full entry for ETRN.  Problem noted by
-		Penelope Fudd, patch from Neil Rickert of Northern Illinois
-		University.
-	FallbackSmartHost should also be tried on temporary errors.
-		From John Beck of Sun Microsystems.
-	When a server responds with 421 to the STARTTLS command then treat
-		it as a temporary error, not as protocol error.  Problem
-		noted by Andrey J. Melnikoff.
-	Properly define two functions in libsm as static because their
-		prototype used static too.  Patch from Peter Klein.
-	Fix syntax errors in helpfile for MAIL and RCPT commands.
-	LIBMILTER: When smfi_replacebody() is called with bodylen equals
-		zero then do not silently ignore that call.  Patch from
-		Gurusamy Sarathy of Active State.
-	LIBMILTER: Recognize "421" also in a multi-line reply to terminate
-		the SMTP session with that error.  Fix from Brian Kantor.
-	Portability: New option HASSNPRINTF which can be set if the OS
-			has a properly working snprintf(3) to get rid
-			of the last two (safe) sprintf(3) calls in the
-			source code.
-		Add support for AIX 5.3.
-		Add support for SunOS 5.11 (aka Solaris 11).
-		Add support for Darwin 8.x.  Patch from Lyndon Nerenberg.
-		OpenBSD 3.7 has removed support for NETISO.
-	CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X.
-		Set DontBlameSendmail to AssumeSafeChown and
-			GroupWritableDirPathSafe for OSTYPE(darwin).
-			Patch from Lyndon Nerenberg.
-		Some features still used 4.7.1 as enhanced status code which
-			was supposed to be eliminated in 8.13.0 because some
-			broken systems misinterpret it as a permanent error.
-			Patch from Matej Vela of Rudjer Boskovic Institute.
-		Some default values in a generated cf file did not match
-			the defaults in the sendmail binary.  Problem noted
-			by Mike Pechkin.
-	New Files:

-
-8.13.4/8.13.4	2005/03/27
-	The bug fixes in 8.13.3 for connection handling uncovered a
-		different error which could result in connections that
-		stay in CLOSE_WAIT state due to a variable that was not
-		properly initialized.  Problem noted by Michael Sims.
-	Deal with empty hostnames in hostsignature().  This bug could lead
-		to an endless loop when doing LMTP deliveries to another
-		host.  Problem first reported by Martin Lathoud and
-		tracked down by Gael Roualland.
-	Make sure return parameters are initialized in getmxrr().  Problem
-		found by Gael Roualland using valgrind.
-	If shared memory is used and the RunAsUser option is set, then the
-		owner and group of the shared memory segment is set to
-		the ids specified RunAsUser and the access mode is set
-		to 0660 to allow for updates by sendmail processes.
-	The number of queue entries that is (optionally) kept in shared
-		memory was wrong in some cases, e.g., envelope splitting
-		and bounce generation.
-	Undo a change made in 8.13.0 to silently truncate long strings
-		in address rewriting because the message can be triggered
-		for header checks where long strings are legitimate.
-		Problem reported by Mary Verge DeSisto, and tracked
-		down with the help of John Beck of Sun Microsystems.
-	The internal stab map did not obey the -m flag.  Patch from
-		Rob McMahon of Warwick University, England.
-	The socket map did not obey the -f flag.  Problem noted by
-		Dan Ringdahl, forwarded by Andrzej Filip.
-	The addition of LDAP recursion in 8.13.0 broke enforcement of
-		the LDAP map -1 argument which tells the MTA to only
-		return success if and only if a single LDAP match is found.
-	Add additional error checks in the MTA for milter communication
-		to avoid a possible segmentation fault.  Based on patch
-		by Joe Maimon.
-	Do not trigger an assertion if X509_digest() returns success but
-		does not assign a value to its output parameter.  Based
-		on patch by Brian Kantor.
-	Add more checks when resetting internal AUTH data (applies only
-		to Cyrus SASL version 2).  Otherwise an SMTP session might
-		be dropped after an AUTH failure.
-	Portability:
-		Add LA_LONGLONG as valid LA_TYPE type for systems that use
-			"long long" to read load average data, e.g.,
-			AIX 5.1 in 32 bit mode.  Note: this has to be set
-			"by hand", it is not (yet) automatically detected.
-			Problem noted by Burak Bilen.
-		Use socklen_t for accept(), etc. on AIX 5.x.  This should
-			fix problems when compiling in 64 bit mode.

-8.13.3/8.13.3	2005/01/11
-	Enhance handling of I/O errors, especially EOF, when STARTTLS
-		is active.
-	Make sure a connection is not reused after it has been closed
-		due to a 421 error.  Problem found by Allan E Johannesen
-		of Worcester Polytechnic Institute.
-	Avoid triggering an assertion when sendmail is interrupted while
-		closing a connection.  Problem found by Allan E Johannesen
-		of Worcester Polytechnic Institute.
-	Regression: a change in 8.13.2 caused sendmail not to try the
-		next MX host (or FallbackMXhost if configured) when, at
-		connection open, the current server returns a 4xy or 5xy
-		SMTP reply code.  Problem noted by Mark Tranchant.
-
-8.13.2/8.13.2	2004/12/15
-	Do not split the first header even if it exceeds the internal
-		buffer size.  Previously a part of such a header would
-		end up in the body of the message.  Problem noted by
-		Simple Nomad of BindView.
-	Do not complain about "cataddr: string too long" when checking
-		headers that do not contain RFC 2822 addresses.
-		Problem noted by Rich Graves of Brandeis University.
-	If a server returns a 421 reply to the RSET command between
-		message deliveries, do not attempt to deliver any more
-		messages on that connection.  This prevents bogus "Bad
-		file number" recipient status.  Problem noted by
-		Allan E Johannesen of Worcester Polytechnic Institute.
-	Allow trailing white space in EHLO command as recommended by RFC
-		2821.  Problem noted by Ralph Santagato of SBC Services.
-	Deal with clients which use AUTH but negotiate a smaller buffer size
-		for data exchanges than the value used by sendmail, e.g.,
-		Cyrus IMAP lmtp server.  Based on patch by Jamie Clark.
-	When passing ESMTP arguments for RCPT to a milter, do not cut
-		them off at a comma.  Problem noted by Krzysztof Oledzki.
-	Add more logging to milter change header functions to
-		complement existing logging.  Based on patch from
-		Gurusamy Sarathy of Active State.
-	Include <lber.h> in include/sm/config.h when LDAPMAP is defined.
-		Patch from Edgar Hoch of the University of Stuttgart.
-	Fix DNS lookup if IPv6 is enabled when converting an IP address
-		to a hostname for use with SASL.  Problem noted by Ken Jones;
-		patch from Hajimu UMEMOTO.
-	CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog
-		mailer.  Patch from John Beck of Sun Microsystems.
-	LIBMILTER: It was possible that xxfi_abort() was called after
-		xxfi_eom() for a message if some timeouts were triggered.
-		Patch from Alexey Kravchuk.
-	LIBMILTER: Slightly rearrange mutex use in listener.c to allow
-		different threads to call smfi_opensocket() and smfi_main().
-		Patch from Jordan Ritter of Cloudmark.
-	MAIL.LOCAL: Properly terminate MBDB before exiting.  Problem
-		noted by Nelson Fung.
-	MAIL.LOCAL: make strip-mail.local used a wrong path to access
-		mail.local.  Problem noted by William Park.
-	VACATION: Properly terminate MBDB before exiting.  Problem noted

-8.13.1/8.13.1	2004/07/30
-	Using the default AliasFile ldap: specification would cause the
-		objectClasses of the LDAP response to be included in the
-		alias expansion.  Problem noted by Brenden Conte of
-		Rensselaer Polytechnic Institute.
-	Fix support for a fallback smart host for system where DNS is
-		(partially) available. From John Beck of Sun Microsystems.
-	Fix SuperSafe=PostMilter behavior when a milter replaces a body
-		but the data file is not yet stored on disk because it is
-		smaller than the size of the memory buffer.  Problem noted
-		by David Russell.
-	Fix certificate revocation list support; if a CRL was specified
-		but the other side presented a cert that was signed by
-		a different (trusted) CA than the one which issued the CRL,
-		verification would always fail.  Problem noted by Al Smith.
-	Run mailer programs as the RunAsUser when RunAsUser is set and
-		the F=S mailer flag is set without a U= mailer equate.
-		Problem noted by John Gardiner Myers of Proofpoint.
-	${nbadrcpts} was off by one if BadRcptThrottle is zero.
-		Patch from Sung-hoon Choi of DreamWiz Inc.
-	CONFIG: Emit a warning if FEATURE(`access_db') is used after
-		FEATURE(`greet_pause') because then the latter will not
-		use the access map.  Note: if no default value is given
-		for FEATURE(`greet_pause') then it issues an error if
-		FEATURE(`access_db') is not specified before it.
-		Problem noted by Alexander Dalloz of University of
-		Bielefeld.
-	CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause')
-		is used to give more flexibility for local changes.
-	Portability:
-		Fix a 64 bit problem in the socket map code.  Problem
-			noted by Geoff Adams.
-		NetBSD 2.0F has closefrom(3).  Patch from Andrew Brown.
-		NetBSD can use sysctl(3) to get the number of CPUs in
-			a system.  Patch from Andrew Brown.

-			incompatibilities with various *roff related
-			tools.  Problem tracked down by Per Hedeland.
-	New Files:
-		doc/op/README
-
-8.13.0/8.13.0	2004/06/20
-	Do not include AUTH data in a bounce to avoid leaking confidential
-		information.  See also cf/README about MSP and the section
-		"Providing SMTP AUTH Data when sendmail acts as Client".
-		Problem noted by Neil Rickert of Northern Illinois
-		University.
-	Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n
-		and -DSM_CONF_SETITIMER=0.  Problem noted by Juergen Georgi
-		of RUS University of Stuttgart.
-	Fix bug in conversion from 8bit to quoted-printable. Problem found
-		by Christof Haerens, patch from Per Hedeland.
-	Add support for LDAP recursion based on types given to attribute
-		specifications in an LDAP map definition.  This allows
-		LDAP queries to return a new query, a DN, or an LDAP
-		URL which will in turn be queried.  See the ``LDAP
-		Recursion'' section of doc/op/op.me for more information.
-		Based on patch from Andrew Baucom.
-	Extend the default LDAP specifications for AliasFile
-		(O AliasFile=ldap:) and file classes (F{X}@LDAP) to
-		include support for LDAP recursion via new attributes.
-		See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section
-		of cf/README for more information.
-	New option for LDAP maps: the -w option allows you to specify the
-		LDAP API/protocol version to use.  The default depends on
-		the LDAP library.
-	New option for LDAP maps: the -H option allows you to specify an
-		LDAP URI instead of specifying the LDAP server via -h host
-		and -p port.  This also allows for the use of LDAP over
-		SSL and connections via named sockets if your LDAP
-		library supports it.
-	New compile time flag SM_CONF_LDAP_INITIALIZE: set this if
-		ldap_initialize(3) is available (and LDAPMAP is set).
-	If MaxDaemonChildren is set and a command is repeated too often
-		during a SMTP session then terminate it just like it is
-		done for too many bad SMTP commands.
-	Basic connection rate control support has been added: the daemon
-		maintains the number of incoming connections per client
-		IP address and total in the macros {client_rate} and
-		{total_rate}, respectively.  These macros can be used
-		in the cf file to impose connection rate limits.
-		A new option ConnectionRateWindowSize (default: 60s)
-		determines the length of the interval for which the
-		number of connections is stored.  Based on patch from
-		Jose Marcio Martins da Cruz, Ecole des Mines de Paris.
-	Add optional protection from open proxies and SMTP slammers which
-		send SMTP traffic without waiting for the SMTP greeting.
-		If enabled by the new ruleset greet_pause (see
-		FEATURE(`greet_pause')), sendmail will wait the specified
-		amount of time before sending the initial 220 SMTP
-		greeting.  If any traffic is received before then, a 554
-		SMTP response is sent and all SMTP commands are rejected
-		during that connection.
-	If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP
-		server could sleep for a very long time.  Fix based on
-		patch from Tadashi Kobayashi of IIJ.
-	Fix a potential memory leak in persistent queue runners if the
-		number of entries in the queue exceeds the limit of jobs.
-		Problem noted by Steve Hubert of University of Washington.
-	Do not use 4.7.1 as enhanced status code because some broken systems
-		misinterpret it as a permanent error.
-	New value for SuperSafe: PostMilter which will delay fsync() until
-		all milters accepted the mail.  This can increase
-		performance if many mails are rejected by milters due to
-		body scans.  Based on patch from David F. Skoll.
-	New macro {msg_id} which contains the value of the Message-Id:
-		header, whether provided by the client or generated by
-		sendmail.
-	New macro {client_connections} which contains the number of open
-		connections in the SMTP server for the client IP address.
-		Based on patch from Jose Marcio Martins da Cruz, Ecole des
-		Mines de Paris.
-	sendmail will now remove its pidfile when it exits.  This was done
-		to prevent confusion caused by running sendmail stop
-		scripts two or more times, where the second and subsequent
-		runs would report misleading error messages about sendmail's
-		pid no longer existing.  See section 1.3.15 of doc/op/op.me
-		for a discussion of the implications of this, including
-		how to correct broken scripts which may have depended on
-		the old behavior.  From John Beck of Sun Microsystems.
-	Support per-daemon input filter lists which override the default
-		filter list specified in InputMailFilters.  The filters
-		can be listed in the I= equate of DaemonPortOptions.
-	Do not add all domain prefixes of the hostname to class 'w'.  If
-		your configuration relies on this behavior, you have to
-		add those names to class 'w' yourself.  Problem noted
-		by Sander Eerkes.
-	Support message quarantining in the mail queue.  Quarantined
-		messages are not run on normal queue displays or runs
-		unless specifically requested with -qQ.  Quarantined queue
-		files are named with an hf prefix instead of a qf prefix.
-	The -q command line option now can specify which queue to display
-		or run.  -qQ operates on quarantined queue items.  -qL
-		operates on lost queue items.
-	Restricted mail queue runs and displays can be done based on the
-		quarantined reason using -qQtext to run or display
-		quarantined items if the quarantine reason contains the
-		given text.  Similarly, -q!Qtext will run or display
-		quarantined items which do not have the given text in the
-		quarantine reason.
-	Items in the queue can be quarantined or unquarantined using the
-		new -Q option.  See doc/op/op.me for more information.
-	When displaying the quarantine mailq with 'mailq -qQ', the
-		quarantine reason is shown in a new line prefixed by
-		"QUARANTINE:".
-	A new error code for the $#error mailer, $@ quarantine, can be used
-		to quarantine messages in check_* (except check_compat) and
-		header check rulesets.  The $: of the mailer triplet will
-		be used for the quarantine reason.
-	Add a new quarantine count to the mailstats collected.
-	Add a new macro ${quarantine} which is the quarantine reason for a
-		message if it is quarantined.
-	New map type "socket" for a trivial query protocol over UNIX domain
-		or TCP sockets (requires compile time option SOCKETMAP).
-		See sendmail/README and doc/op/op.me for details as well as
-		socketmapServer.pl and socketmapClient.pl in contrib.
-		Code donated by Bastiaan Bakker of LifeLine Networks.
-	Define new macro ${client_ptr} which holds the result of the PTR
-		lookup for the client IP address.  Note: this is the same
-		as ${client_name} if and only if ${client_resolve} is OK.
-	Add a new macro ${nbadrcpts} which contains the number of bad
-		recipients received so far in a transaction.
-	Call check_relay with the value of ${client_name} to deal with bogus
-		DNS entries.  See also FEATURE(`use_client_ptr').  Problem
-		noted by Kai Schlichting.
-	Treat Delivery-Receipt-To: headers the same as Return-Receipt-To:
-		headers (turn them into DSNs).  Delivery-Receipt-To: is
-		apparently used by SIMS (Sun Internet Mail System).
-	Enable connection caching for LPC mailers.  Patch from Christophe
-		Wolfhugel of France Telecom Oleane.
-	Do not silently truncate long strings in address rewriting.
-	Add support for Cyrus SASL version 2.  From Kenneth Murchison of
-		Oceana Matrix Ltd.
-	Add a new AuthOption=m flag to require the use of mechanisms which
-		support mutual authentication.  From Kenneth Murchison of
-		Oceana Matrix Ltd.
-	Fix logging of TLS related problems (introduced in 8.12.11).
-	The macros {auth_author} and {auth_authen} are stored in xtext
-		format just like the STARTTLS related macros to avoid
-		problems with parsing them.  Problem noted by Pierangelo
-		Masarati of SysNet s.n.c.
-	New option AuthRealm to set the authentication realm that is
-		passed to the Cyrus SASL library.  Patch from Gary Mills
-		of the University of Manitoba.
-	Enable AUTH mechanism EXTERNAL if STARTTLS verification was
-		successful, otherwise relaying would be allowed if
-		EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS
-		is active.
-	Add basic support for certificate revocation lists.  Note: if a
-		CRLFile is specified but the file is unusable, STARTTLS
-		is disabled.  Based on patch by Ralf Hornik.
-	Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms
-		DIGEST-MD5 and LOGIN.
-	Write pid to file also if sendmail only acts as persistent queue
-		runner.  Proposed by Gary Mills of the University of Manitoba.
-	Keep daemon pid file(s) locked so other daemons don't try to
-		overwrite each other's pid files.
-	Increase maximum length of logfile fields for {cert_subject} and
-		{cert_issuer} from 128 to 256.  Requested by Christophe
-		Wolfhugel of France Telecom.
-	Log the TLS verification message on the STARTTLS= log line at
-		LogLevel 12 or higher.
-	If the MSP is invoked with the verbose option (-v) then it will
-		try to use the SMTP command VERB to propagate this option
-		to the MTA which in turn will show the delivery just like
-		it was done before the default 8.12 separation of MSP and
-		MTA.  Based on patch by Per Hedeland.
-	If a daemon is refusing connections for longer than the time specified
-		by the new option RejectLogInterval (default: 3 hours) due
-		to high load, log this information.  Patch from John Beck
-		of Sun Microsystems.
-	Remove the ability for non-trusted users to raise the value of
-		CheckpointInterval on the command line.
-	New mailer flag 'B' to strip leading backslashes, which is a
-		subset of the functionality of the 's' flag.
-	New mailer flag 'W' to ignore long term host status information.
-		Patch from Juergen Georgi of RUS University of Stuttgart.
-	Enable generic mail filter API (milter) by default.  To turn
-		it off, add -DMILTER=0 to the compile time options.
-	An internal SMTP session discard flag was lost after an RSET/HELO/EHLO
-		causing subsequent messages to be sent instead of being
-		discarded.  This also caused milter callbacks to be called
-		out of order after the SMTP session was reset.
-	New option RequiresDirfsync to turn off the compile time flag
-		REQUIRES_DIR_FSYNC at runtime.  See sendmail/README for
-		further information.
-	New command line option -D logfile to send debug output to
-		the indicated log file instead of stdout.
-	Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control
-		queue return and warning times for delivery status
-		notifications.
-	New queue sort order option: 'n'one for not sorting the queue entries
-		at all.
-	Several more return values for ruleset srv_features have been added
-		to enable/disable certain features in the server per
-		connection.  See doc/op/op.me for details.
-	Support for SMTP over SSL (smtps), activated by Modifier=s
-		for DaemonPortOptions.
-	Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when
-		trying to canonify hostnames.  Suggested by Neil Rickert
-		of Northern Illinois University.
-	Add support for a fallback smart host (option FallbackSmartHost) to
-		be tried as a last resort after all other fallbacks.  This
-		is designed for sites with partial DNS (e.g., an accurate
-		view of inside the company, but an incomplete view of
-		outside).  From John Beck of Sun Microsystems.
-	Enable timeout for STARTTLS even if client does not start the TLS
-		handshake.  Based on patch by Andrey J. Melnikoff.
-	Remove deprecated -v option for PH map, use -k instead.  Patch from
-		Mark Roth of the University of Illinois at Urbana-Champaign.
-	libphclient is version 1.2.x by default, if version 1.1.x is required
-		then compile with -DNPH_VERSION=10100.  Patch from Mark Roth
-		of the University of Illinois at Urbana-Champaign.
-	Add Milter.macros.eom, allowing macros to be sent to milter
-		applications for use in the xxfi_eom() callback.
-	New macro {time} which contains the output of the time(3) function,
-		i.e., the number of seconds since 0 hours, 0 minutes,
-		0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
-	If check_relay sets the reply code to "421" the SMTP server will
-		terminate the SMTP session with a 421 error message.
-	Get rid of dead code that tried to access the environment variable
-		HOSTALIASES.
-	Deprecate the use of ErrorMode=write.  To enable this in 8.13
-		compile with -DUSE_TTYPATH=1.
-	Header check rulesets using $>+ (do not strip comments) will get
-		the header value passed in without balancing quotes,
-		parentheses, and angle brackets.  Based on patch from
-		Oleg Bulyzhin.
-	Do not complain and fix up unbalanced quotes, parentheses, and
-		angle brackets when reading in rulesets.  This allows
-		rules to be written for header checks to catch strings
-		that contain quotes, parentheses, and/or angle brackets.
-		Based on patch from Oleg Bulyzhin.
-	Do not close socket when accept(2) in the daemon encounters
-		some temporary errors like ECONNABORTED.
-	Added list of CA certificates that are used by members of the
-		sendmail consortium, see CACerts.
-	Portability:
-		Two new compile options have been added:
-			HASCLOSEFROM	System has closefrom(3).
-			HASFDWALK	System has fdwalk(3).
-			Based on patch from John Beck of Sun Microsystems.
-		The Linux kernel version 2.4 series has a broken flock() so
-			change to using fcntl() locking until they can fix
-			it.  Be sure to update other sendmail related
-			programs to match locking techniques.
-		New compile time option NEEDINTERRNO which should be set
-			if <errno.h> does not declare errno itself.
-		Support for UNICOS/mk and UNICOS/mp added, some changes for
-			UNICOS.  Patches contributed by Aaron Davis and
-			Brian Ginsbach, Cray Inc., and Manu Mahonen of
-			Center for Scientific Computing.
-		Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
-		Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther).
-		Remove path from compiler definition for Interix because
-			Interix 3.0 and 3.5 put gcc in different locations.
-			Also use <sys/mkdev.h> to get the correct
-			major()/minor() definitions.  Based on feedback
-			from Mark Funkenhauser.
-	CONFIG: Add support for LDAP recursion to the default LDAP searches
-		for maps via new attributes.  See the ``USING LDAP FOR
-		ALIASES, MAPS, and CLASSES'' section of cf/README and
-		cf/sendmail.schema for more information.
-	CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER
-		is of the form "user:group" when used for submit.mc.
-		Problem noted by Carsten P. Gehrke, patch from Neil Rickert
-		of Northern Illinois University.
-	CONFIG: Add a new access DB value of QUARANTINE:reason which
-		instructs the check_* (except check_compat) to quarantine
-		the message using the given reason.
-	CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl)
-		instead of "host" to avoid problem with looking up other
-		DNS records than just A.
-	CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the
-		length of the interval for which the number of incoming
-		connections is maintained.
-	CONFIG: New FEATURE(`ratecontrol') to set the limits for connection
-		rate control for individual hosts or nets.
-	CONFIG: New FEATURE(`conncontrol') to set the limits for the
-		number of open SMTP connections for individual hosts or nets.
-	CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP
-		slamming protection described above.  The feature can
-		take an argument specifying the milliseconds to wait and/or
-		use the access database to look the pause time based on
-		client hostname, domain, IP address, or subnet.
-	CONFIG: New FEATURE(`use_client_ptr') to have check_relay use
-		$&{client_ptr} as its first argument.  This is useful for
-		rejections based on the unverified hostname of client,
-		which turns on the same behavior as in earlier sendmail
-		versions when delay_checks was not in use.  See also entry
-		above about check_relay being invoked with ${client_name}.
-	CONFIG: New option confREJECT_LOG_INTERVAL to specify the log
-		interval when refusing connections for this long.
-	CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases
-		this requires a change in a mc file.  Requested by
-		Ted Roberts of Electronic Data Systems.
-	CONFIG: New option confAUTH_REALM to set the authentication realm
-		that is passed to the Cyrus SASL library.  Patch from
-		Gary Mills of the University of Manitoba.
-	CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src}
-		to follow the naming conventions.
-	CONFIG: Add a third optional argument to local_lmtp to specify
-		the A= argument.

-		local_lmtp.
-	CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile
-		time flag REQUIRES_DIR_FSYNC at runtime.
-	CONFIG: New LOCAL_UUCP macro to insert rules into the generated
-		cf file at the same place where MAILER(`uucp') inserts
-		its rules.
-	CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN
-		to control queue return and warning times for delivery
-		status notifications.
-	CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost.
-	CONFIG: Add the mc file which has been used to create the cf
-		file to the end of the cf file when using make in cf/cf/.
-		Patch from Richard Rognlie.
-	CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9.
-		Use ServiceSwitchFile to turn off DNS lookups, see
-		doc/op/op.me.
-	CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom
-		option) defines macros to be sent to milter applications for
-		use in the xxfi_eom() callback.
-	CONFIG: New option confCRL to specify file which contains
-		certificate revocations lists.
-	CONFIG: Add a new value (sendertoo) for the third argument to
-		FEATURE(`ldap_routing') which will reject the SMTP
-		MAIL From: command if the sender address doesn't exist
-		in LDAP.  See cf/README for more information.
-	CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which
-		instructs the rulesets on whether or not to do a domain
-		lookup if a full address lookup doesn't match.  See cf/README
-		for more information.
-	CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which
-		instructs the rulesets on whether or not to queue the mail
-		or give an SMTP temporary error if the LDAP server can't be
-		reached.  See cf/README for more information.  Based on
-		patch from Billy Ray Miller of Caterpillar.
-	CONFIG: Experimental support for MTAMark, see cf/README for details.
-	CONFIG: New option confMESSAGEID_HEADER to define a different
-		Message-Id: header format.  Patch from Bastiaan Bakker
-		of LifeLine Networks.
-	CONTRIB: New version of cidrexpand which uses Net::CIDR.  From
-		Derek J. Balling.
-	CONTRIB: oldbind.compat.c has been removed due to security problems.
-		Found by code inspection done by Reasoning, Inc.
-	DEVTOOLS: Add an example file for devtools/Site/, contributed
-		by Neil Rickert of Northern Illinois University.
-	LIBMILTER: Add new function smfi_quarantine() which allows the
-		filter's EOM routine to quarantine the current message.
-		Filters which use this function must include the
-		SMFIF_QUARANTINE flag in the registered smfiDesc structure.
-	LIBMILTER: If a milter sets the reply code to "421", the SMTP server
-		will terminate the SMTP session with that error.
-	LIBMILTER: Upon filter shutdown, libmilter will not remove a
-		named socket in the file system if it is running as root.
-	LIBMILTER: Add new function smfi_progress() which allows the filter
-		to notify the MTA that an EOM operation is still in progress,
-		resetting the timeout.
-	LIBMILTER: Add new function smfi_opensocket() which allows the filter
-		to attempt to establish the interface socket, and detect
-		failure to do so before calling smfi_main().
-	LIBMILTER: Add new function smfi_setmlreply() which allows the
-		filter to return a multi-line SMTP reply.
-	LIBMILTER: Deal with more temporary errors in accept() by ignoring
-		them instead of stopping after too many occurred.
-		Suggested by James Carlson of Sun Microsystems.
-	LIBMILTER: Fix a descriptor leak in the sample program found in
-		docs/sample.html.  Reported by Dmitry Adamushko.
-	LIBMILTER: The sample program also needs to use SMFIF_ADDRCPT.
-		Reported by Carl Byington of 510 Software Group.
-	LIBMILTER: Document smfi_stop() and smfi_setdbg().  Patches
-		from Bryan Costales.
-	LIBMILTER: New compile time option SM_CONF_POLL; define this if
-		poll(2) should be used instead of select(2).
-	LIBMILTER: New function smfi_insheader() and related protocol
-		amendments to support header insertion operations.
-	MAIL.LOCAL: Add support for hashed mail directories, see
-		mail.local/README.  Contributed by Chris Adams of HiWAAY
-		Informations Services.
-	MAILSTATS: Display quarantine message counts.
-	MAKEMAP: Add new flag -D to specify the comment character to use
-		instead of '#'.
-	VACATION: Add new flag -j to auto-respond to messages regardless of
-		whether or not the recipient is listed in the To: or Cc:
-		headers.
-	VACATION: Add new flag -R to specify the envelope sender address
-		for the auto-response message.

-8.12.11/8.12.11	2004/01/18
-	Use QueueFileMode when opening qf files.  This error was a
-		regression in 8.12.10.  Problem detected and diagnosed
-		Lech Szychowski of the Polish Power Grid Company.
-	Properly count the number of queue runners in a work group and
-		make sure the total limit of MaxQueueChildren is not
-		exceeded.  Based on patch from Takayuki Yoshizawa of
-		Techfirm, Inc.
-	Take care of systems that can generate time values where the
-		seconds can exceed the usual range of 0 to 59.
-		Problem noted by Randy Diffenderfer of EDS.
-	Avoid regeneration of identical queue identifiers by processes
-		whose process id is the same as that of the initial
-		sendmail process that was used to start the daemon.
-		Problem noted by Randy Diffenderfer of EDS.
-	When a milter invokes smfi_delrcpt() compare the supplied
-		recipient address also against the printable addresses
-		of the current list to deal with rewritten addresses.
-		Based on patch from Sean Hanson of The Asylum.
-	BadRcptThrottle now also works for addresses which return the
-		error mailer, e.g., virtusertable entries with the
-		right hand side error:.  Patch from Per Hedeland.
-	Fix printing of 8 bit characters as octals in log messages.
-		Based on patch by Andrey J. Melnikoff.
-	Undo change of algorithm for MIME 7-bit base64 encoding to 8-bit
-		text that has been introduced in 8.12.3.  There are some
-		examples where the new code fails, but the old code works.
-		To get the 8.12.3-8.12.10 version, compile sendmail with
-		-DMIME7TO8_OLD=0.  If you have an example of improper
-		7 to 8 bit conversion please send it to us.
-	Return normal error code for unknown SMTP commands instead of
-		the one specified by check_relay or a milter for a
-		connection.  Problem noted by Andrzej Filip.
-	Some ident responses contain data after the terminating CRLF which
-		causes sendmail to log "POSSIBLE ATTACK...newline in string".
-		To avoid this everything after LF is ignored.
-	If the operating system supports O_EXLOCK and HASFLOCK is set
-		then a possible race condition for creating qf files
-		can be avoided.  Note: the race condition does not
-		exist within sendmail, but between sendmail and an
-		external application that accesses qf files.
-	Log the proper options name for TLS related mising files for
-		the CACertPath, CACertFile, and DHParameters options.
-	Do not split an envelope if it will be discarded, otherwise df
-		files could be left behind.  Problem found by Wolfgang
-		Breyha.
-	The use of the environment variables HOME and HOSTALIASES has been
-		deprecated and will be removed in version 8.13.  This only
-		effects configuration which preserve those variable via the
-		'E' command in the cf file as sendmail clears out its entire
-		environment.
-	Portability:
-		Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
-		Solaris 10 has unsetenv(), patch from Craig Mohrman of
-			Sun Microsystems.
-	LIBMILTER: Add extra checks in case a broken MTA sends bogus data
-		to libmilter.  Based on code review by Rob Grzywinski.
-	SMRSH: Properly assemble commands that contain '&&' or '||'.
-		Problem noted by Eric Lee of Talking Heads.
-	New Files:

-8.12.10/8.12.10	2003/09/24 (Released: 2003/09/17)
-	SECURITY: Fix a buffer overflow in address parsing.  Problem
-		detected by Michal Zalewski, patch from Todd C. Miller
-		of Courtesan Consulting.
-	Fix a potential buffer overflow in ruleset parsing.  This problem
-		is not exploitable in the default sendmail configuration;
-		only if non-standard rulesets recipient (2), final (4), or
-		mailer-specific envelope recipients rulesets are used then
-		a problem may occur.  Problem noted by Timo Sirainen.
-	Accept 0 (and 0/0) as valid input for set MaxMimeHeaderLength.
-		Problem noted by Thomas Schulz.
-	Add several checks to avoid (theoretical) buffer over/underflows.
-	Properly count message size when performing 7->8 or 8->7 bit MIME
-		conversions.  Problem noted by Werner Wiethege.
-	Properly compute message priority based on size of entire message,
-		not just header.  Problem noted by Axel Holscher.
-	Reset SevenBitInput to its configured value between SMTP
-		transactions for broken clients which do not properly
-		announce 8 bit data.  Problem noted by Stefan Roehrich.
-	Set {addr_type} during queue runs when processing recipients.
-		Based on patch from Arne Jansen.
-	Better error handling in case of (very unlikely) queue-id conflicts.
-	Perform better error recovery for address parsing, e.g., when
-		encountering a comment that is too long.  Problem noted by
-		Tanel Kokk, Union Bank of Estonia.
-	Add ':' to the allowed character list for bogus HELO/EHLO
-		checking.  It is used for IPv6 domain literals.  Patch from
-		Iwaizako Takahiro of FreeBit Co., Ltd.
-	Reset SASL connection context after a failed authentication attempt.
-		Based on patch from Rob Siemborski of CMU.
-	Check Berkeley DB compile time version against run time version
-		to make sure they match.
-	Do not attempt AAAA (IPv6) DNS lookups if IPv6 is not enabled
-		in the kernel.
-	When a milter adds recipients and one of them causes an error,
-		do not ignore the other recipients.  Problem noted by
-		Bart Duchesne.
-	CONFIG: Use specified SMTP error code in mailertable entries which
-		lack a DSN, i.e., "error:### Text".  Problem noted by
-		Craig Hunt.
-	CONFIG: Call Local_trust_auth with the correct argument.  Patch
-		from Jerome Borsboom.
-	CONTRIB: Better handling of temporary filenames for doublebounce.pl
-		and expn.pl to avoid file overwrites, etc.  Patches from
-		Richard A. Nelson of Debian and Paul Szabo.
-	MAIL.LOCAL: Fix obscure race condition that could lead to an
-		improper mailbox truncation if close() fails after the
-		mailbox is fsync()'ed and a new message is delivered
-		after the close() and before the truncate().
-	MAIL.LOCAL: If mail delivery fails, do not leave behind a
-		stale lockfile (which is ignored after the lock timeout).
-		Patch from Oleg Bulyzhin of Cronyx Plus LLC.
-	Portability:
-		Port for AIX 5.2.  Thanks to Steve Hubert of University
-			of Washington for providing access to a computer
-			with AIX 5.2.
-		setreuid(2) works on OpenBSD 3.3.  Patch from
-			Todd C. Miller of Courtesan Consulting.
-		Allow for custom definition of SMRSH_CMDDIR and SMRSH_PATH
-			on all operating systems.  Patch from Robert Harker
-			of Harker Systems.
-		Use strerror(3) on Linux.  If this causes a problem on
-			your Linux distribution, compile with
-			-DHASSTRERROR=0 and tell sendmail.org about it.
-	Added Files:
-		devtools/OS/AIX.5.2
-
-8.12.9/8.12.9	2003/03/29
-	SECURITY: Fix a buffer overflow in address parsing due to
-		a char to int conversion problem which is potentially
-		remotely exploitable.  Problem found by Michal Zalewski.
-		Note: an MTA that is not patched might be vulnerable to
-		data that it receives from untrusted sources, which
-		includes DNS.
-	To provide partial protection to internal, unpatched sendmail MTAs,
-		8.12.9 changes by default (char)0xff to (char)0x7f in
-		headers etc.  To turn off this conversion compile with
-		-DALLOW_255 or use the command line option -d82.101.
-	To provide partial protection for internal, unpatched MTAs that may be
-		performing 7->8 or 8->7 bit MIME conversions, the default
-		for MaxMimeHeaderLength has been changed to 2048/1024.
-		Note: this does have a performance impact, and it only
-		protects against frontal attacks from the outside.
-		To disable the checks and return to pre-8.12.9 defaults,
-		set MaxMimeHeaderLength to 0/0.
-	Do not complain about -ba when submitting mail.  Problem noted
-		by Derek Wueppelmann.
-	Fix compilation with Berkeley DB 1.85 on systems that do not
-		have flock(2).  Problem noted by Andy Harper of Kings
-		College London.
-	Properly initialize data structure for dns maps to avoid various
-		errors, e.g., looping processes.  Problem noted by
-		Maurice Makaay of InterNLnet B.V.
-	CONFIG: Prevent multiple application of rule to add smart host.
-		Patch from Andrzej Filip.
-	CONFIG: Fix queue group declaration in MAILER(`usenet').
-	CONTRIB: buildvirtuser: New option -t builds the virtusertable
-		text file instead of the database map.
-	Portability:
-		Revert wrong change made in 8.12.7 and actually use the
-			builtin getopt() version in sendmail on Linux.
-			This can be overridden by using -DSM_CONF_GETOPT=0
-			in which case the OS supplied version will be used.
-
-8.12.8/8.12.8	2003/02/11
-	SECURITY: Fix a remote buffer overflow in header parsing by
-		dropping sender and recipient header comments if the
-		comments are too long.  Problem noted by Mark Dowd
-		of ISS X-Force.
-	Fix a potential non-exploitable buffer overflow in parsing the
-		.cf queue settings and potential buffer underflow in
-		parsing ident responses.  Problem noted by Yichen Xie of
-		Stanford University Compilation Group.
-	Fix ETRN #queuegroup command: actually start a queue run for
-		the selected queue group.  Problem noted by Jos Vos.
-	If MaxMimeHeaderLength is set and a malformed MIME header is fixed,
-		log the fixup as "Fixed MIME header" instead of "Truncated
-		MIME header".  Problem noted by Ian J Hart.
-	CONFIG: Fix regression bug in proto.m4 that caused a bogus
-		error message: "FEATURE() should be before MAILER()".
-	MAIL.LOCAL: Be more explicit in some error cases, i.e., whether
-		a mailbox has more than one link or whether it is not
-		a regular file.  Patch from John Beck of Sun Microsystems.
-
-8.12.7/8.12.7	2002/12/29
-	Properly clean up macros to avoid persistence of session data
-		across various connections.  This could cause session
-		oriented restrictions, e.g., STARTTLS requirements,
-		to erroneously allow a connection.  Problem noted
-		by Tim Maletic of Priority Health.
-	Do not lookup MX records when sorting the MSP queue.  The MSP
-		only needs to relay all mail to the MTA.  Problem found
-		by Gary Mills of the University of Manitoba.
-	Do not restrict the length of connection information to 100
-		characters in some logging statements.  Problem noted by
-		Erik Parker.
-	When converting an enhanced status code to an exit status, use
-		EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5
-		is used.
-	Reset macro $x when receiving another MAIL command.  Problem
-		noted by Vlado Potisk of Wigro s.r.o.
-	Don't bother setting the permissions on the build area statistics
-		file, the proper permissions will be put on the file at
-		install time.  This fixes installation over NFS for some
-		users.  Problem noted by Martin J. Dellwo of 3-Dimensional
-		Pharmaceuticals, Inc.
-	Fix problem of decoding SASLv2 encrypted data.  Problem noted by
-		Alex Deiter of Mobile TeleSystems, Komi Republic.
-	Log milter socket open errors at MilterLogLevel 1 or higher instead
-		of 11 or higher.
-	Print early system errors to the console instead of silently
-		exiting.  Problem noted by James Jong of IBM.
-	Do not process a queue group if Runners is set to 0, regardless
-		of whether F=f or sendmail is run in verbose mode (-v).
-		The use of -qGname will still force queue group "name"
-		to be run even if Runners=0.
-	Change the level for logging the fact that a daemon is refusing
-		connections due to high load from LOG_INFO to LOG_NOTICE.
-		Patch from John Beck of Sun Microsystems.
-	Use location information for submit.cf from NetInfo
-		(/locations/sendmail/submit.cf) if available.
-	Re-enable ForkEachJob which was lost in 8.12.0.  Problem noted by
-		Neil Rickert of Northern Illinois University.
-	Make behavior of /canon in debug mode consistent with usage in
-		rulesets.  Patch from Shigeno Kazutaka of IIJ.
-	Fix a potential memory leak in envelope splitting.  Problem noted
-		by John Majikes of IBM.
-	Do not try to share an mailbox database LDAP connection across
-		different processes.  Problem noted by Randy Kunkee.
-	Fix logging for undelivered recipients when the SMTP connection
-		times out during message collection.  Problem noted by Neil
-		Rickert of Northern Illinois University.
-	Avoid problems with QueueSortOrder=random due to problems with
-		qsort() on Solaris (and maybe some other operating systems).
-		Problem noted by Stephan Schulz of Gruner+Jahr..
-	If -f "" is specified, set the sender address to "<>".  Problem
-		noted by Matthias Andree.
-	Fix formatting problem of footnotes for plain text output on some
-		versions of tmac.  Patch from Per Hedeland.
-	Portability:
-		Berkeley DB 4.1 support (requires at least 4.1.25).
-		Some getopt(3) implementations in GNU/Linux are broken
-			and pass a NULL pointer to an option which requires
-			an argument, hence the builtin version of
-			sendmail is used instead.  This can be overridden
-			by using -DSM_CONF_GETOPT=0.  Problem noted by
-			Vlado Potisk of Wigro s.r.o.
-		Support for nph-1.2.0 from Mark D. Roth of the University
-			of Illinois at Urbana-Champaign.
-		Support for FreeBSD 5.0's MAC labeling from Robert Watson
-			of the TrustedBSD Project.
-		Support for reading the number of processors on an IRIX
-			system from Michel Bourget of SGI.

-		Interix support from Nedelcho Stanev of Atlantic Sky
-			Corporation.
-		Update Mac OS X/Darwin portability from Wilfredo Sanchez.
-	CONFIG: Enforce tls_client restrictions even if delay_checks
-		is used.  Problem noted by Malte Starostik.
-	CONFIG: Deal with an empty hostname created via bogus
-		DNS entries to get around access restrictions.
-		Problem noted by Kai Schlichting.
-	CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default
-		to avoid problems with hostname resolution for localhost
-		which on many systems does not resolve to 127.0.0.1 (or
-		::1 for IPv6).  If you do not use IPv4 but only IPv6 then
-		you need to change submit.mc accordingly, see the comment
-		in the file itself.
-	CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid
-		error messages from initgroups(3) on AIX 4.3 when sending
-		mail to non-existing users. Problem noted by Mark Roth of
-		the University of Illinois at Urbana-Champaign.
-	CONFIG: Allow local_procmail to override local_lmtp settings.
-	CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to
-		relay.
-	CONTRIB: cidrexpand: Deal with the prefix tags that may be included
-		in access_db.
-	CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell.
-	LIBMILTER: On Solaris libmilter may get into an endless loop if
-		an error in the communication from/to the MTA occurs.
-		Patch from Gurusamy Sarathy of Active State.
-	LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64.
-		Patch from from Jose Marcio Martins da Cruz of Ecole
-		Nationale Superieure des Mines de Paris.
-	MAIL.LOCAL: Fix a truncation race condition if the close() on
-		the mailbox fails.  Problem noted by Tomoko Fukuzawa of
-		Sun Microsystems.
-	MAIL.LOCAL: Fix a potential file descriptor leak if mkstemp(3)
-		fails.  Patch from John Beck of Sun Microsystems.
-	SMRSH: SECURITY: Only allow regular files or symbolic links to be
-		used for a command.  Problem noted by David Endler of
-		iDEFENSE, Inc.
-	New Files:
-		devtools/OS/Interix
-		include/sm/bdb.h
-
-8.12.6/8.12.6	2002/08/26
-	Do not add the FallbackMXhost (or its MX records) to the list
-		returned by the bestmx map when -z is used as option.
-		Otherwise sendmail may act as an open relay if FallbackMXhost
-		and FEATURE(`relay_based_on_MX') are used together.
-		Problem noted by Alexander Ignatyev.
-	Properly split owner- mailing list messages when SuperSafe is set
-		to interactive.  Problem noted by Todd C. Miller of
-		Courtesan Consulting.
-	Make sure that an envelope is queued in the selected queue group
-		even if some recipients are deleted or invalid.  Problem
-		found by Chris Adams of HiWAAY Informations Services.
-	Do not send a bounce message if a message is completely collected
-		from the SMTP client.  Problem noted by Kari Hurtta of the
-		Finnish Meteorological Institute.
-	Provide an 'install-submit-st' target for sendmail/Makefile to
-		install the MSP statistics file using the file named in the
-		confMSP_STFILE devtools variable.  Requested by Jeff
-		Earickson of Colby College.
-	Queue up mail with a temporary error if setusercontext() fails
-		during a delivery attempt.  Patch from Todd C. Miller of
-		Courtesan Consulting.
-	Fix handling of base64 encoded client authentication data for
-		SMTP AUTH.  Patch from Elena Slobodnik of life medien GmbH.
-	Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries
-		restart interrupted system calls.  Problem noted by Luiz
-		Henrique Duma of BSIOne.
-	Prevent a segmentation fault if a program passed a NULL envp using
-		execve().
-	Document a problem with the counting of queue runners that may
-		cause delays if MaxQueueChildren is set too low. Problem
-		noted by Ian Duplisse of Cable Television Laboratories, Inc.
-	If discarding a message based on a recipient, don't try to look up
-		the recipient in the mailbox database if F=w is set.  This
-		allows users to discard bogus recipients when dealing with
-		spammers without tipping them off.  Problem noted by Neil
-		Rickert of Northern Illinois University.
-	If applying a header check to a header with unstructured data,
-		e.g., Subject:, then do not run syntax checks that are
-		supposed for addresses on the header content.
-	Count messages rejected/discarded via the check_data ruleset.
-	Portability:
-		Fix compilation on systems which do not allow simple
-			copying of the variable argument va_list.  Based on
-			fix from Scott Walters.
-		Fix NSD map open bug.  From Michel Bourget of SGI.
-		Add some additional IRIX shells to the default shell
-			list.  From Michel Bourget of SGI.
-		Fix compilation issues on Mac OS X 10.2 (Darwin 6.0).
-			NETISO support has been dropped.
-	CONFIG: There was a seemingly minor change in 8.12.4 with respect
-		to handling entries of IP nets/addresses with RHS REJECT.
-		These would be rejected in check_rcpt instead of only
-		being activated in check_relay.  This change has been made to
-		avoid potential bogus temporary rejection of relay attempts
-		"450 4.7.1 Relaying temporarily denied. Cannot resolve PTR
-		record for ..." if delay_checks is enabled.  However, this
-		modification causes a change of behavior if an IP net/address
-		is listed in the access map with REJECT and a host/domain
-		name is listed with OK or RELAY, hence it has been reversed
-		such that the behavior of 8.12.3 is restored.  The original
-		change was made on request of Neil Rickert of Northern
-		Illinois University, the side effect has been found by
-		Stefaan Van Hoornick.
-	CONFIG: Make sure delay_checks works even for sender addresses
-		using the local hostname ($j) or domains in class {P}.
-		Based on patch from Neil Rickert of Northern Illinois
-		University.
-	CONFIG: Fix temporary error handling for LDAP Routing lookups.
-		Fix from Andrzej Filip.
-	CONTRIB: New version of etrn.pl script and external man page
-		(etrn.0) from John Beck of Sun Microsystems.
-	LIBMILTER: Protect a free(3) operation from being called with a
-		NULL pointer.  Problem noted by Andrey J. Melnikoff.
-	LIBMILTER: Protect against more interrupted select() calls.  Based
-		on patch from Jose Marcio Martins da Cruz of Ecole Nationale

-8.12.5/8.12.5	2002/06/25
-	SECURITY: The DNS map can cause a buffer overflow if the user
-		specifies a dns map using TXT records in the configuration
-		file and a rogue DNS server is queried.  None of the
-		sendmail supplied configuration files use this option hence
-		they are not vulnerable.  Problem noted independently by
-		Joost Pol of PINE Internet and Anton Rang of Sun Microsystems.
-	Unprintable characters in responses from DNS servers for the DNS
-		map type are changed to 'X' to avoid potential problems
-		with rogue DNS servers.
-	Require a suboption when setting the Milter option.  Problem noted
-		by Bryan Costales.
-	Do not silently overwrite command line settings for
-		DirectSubmissionModifiers.  Problem noted by Bryan
-		Costales.
-	Prevent a segmentation fault when clearing the event list by
-		turning off alarms before checking if event list is
-		empty.  Problem noted by Allan E Johannesen of Worcester
-		Polytechnic Institute.
-	Close a potential race condition in transitioning a memory buffered
-		file onto disk.  From Janani Devarajan of Sun Microsystems.
-	Portability:
-		Include paths.h on Linux systems running glibc 2.0 or later
-			to get the definition for _PATH_SENDMAIL, used by
-			rmail and vacation.  Problem noted by Kevin
-			A. McGrail of Peregrine Hardware.
-		NOTE: Linux appears to have broken flock() again.  Unless
-			the bug is fixed before sendmail 8.13 is shipped,
-			8.13 will change the default locking method to
-			fcntl() for Linux kernel 2.4 and later.  You may
-			want to do this in 8.12 by compiling with
-			-DHASFLOCK=0.  Be sure to update other sendmail
-			related programs to match locking techniques.
-
-8.12.4/8.12.4	2002/06/03
-	SECURITY: Inherent limitations in the UNIX file locking model
-		can leave systems open to a local denial of service
-		attack.  Be sure to read the "FILE AND MAP PERMISSIONS"
-		section of the top level README for more information.
-		Problem noted by lumpy.
-	Use TempFileMode (defaults to 0600) for the permissions of PidFile
-		instead of 0644.
-	Change the default file permissions for new alias database files
-		from 0644 to 0640.  This can be overridden at compile time
-		by setting the DBMMODE macro.
-	Fix a potential core dump problem if the environment variable
-		NAME is set.  Problem noted by Beth A. Chaney of
-		Purdue University.
-	Expand macros before passing them to libmilter.  Problem noted
-		by Jose Marcio Martins da Cruz of Ecole Nationale
-		Superieure des Mines de Paris.
-	Rewind the df (message body) before truncating it when libmilter
-		replaces the body of a message.  Problem noted by Gisle Aas
-		of Active State.
-	Change SMTP reply code for AUTH failure from 500 to 535 and the
-		initial zero-length response to "=" per RFC 2554.  Patches
-		from Kenneth Murchison of Oceana Matrix Ltd.
-	Do not try to fix broken message/rfc822 MIME attachments by
-		inserting a MIME-Version: header when MaxMimeHeaderLength
-		is set and no 8 to 7 bit conversion is needed.  Based on
-		patch from Rehor Petr of ICZ (Czech Republic).
-	Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection
-		is rejected anyway.  Noted by Chris Loelke.
-	Mention the submission mail queue in the mailq man page.  Requested
-		by Bill Fenner of AT&T.
-	Set ${msg_size} macro when reading a message from the command line
-		or the queue.
-	Detach from shared memory before dropping privileges back to
-		user who started sendmail.
-	If AllowBogusHELO is set to false (default) then also complain if
-		the argument to HELO/EHLO contains white space.  Suggested
-		by Seva Gluschenko of Cronyx Plus.
-	Allow symbolicly linked forward files in writable directory paths
-		if both ForwardFileInUnsafeDirPath and
-		LinkedForwardFileInWritableDir DontBlameSendmail options
-		are set.  Problem noted by Werner Spirk of
-		Leibniz-Rechenzentrum Munich.
-	Portability:
-		Operating systems that lack the ftruncate() call will not
-			be able to use Milter's body replacement feature.
-			This only affects Altos, Maxion, and MPE/iX.
-		Digital UNIX 5.0 has changed flock() semantics to be
-			non-compliant.  Problem noted by Martin Mokrejs of
-			Charles University in Prague.
-		The sparc64 port of FreeBSD 5.0 now supports shared
-			memory.
-	CONFIG: FEATURE(`preserve_luser_host') needs the macro map.
-		Problem noted by Andrzej Filip.
-	CONFIG: Using 'local:' as a mailertable value with
-		FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail
-		to be misaddressed.  Problem noted by Andrzej Filip.
-	CONFIG: Provide a workaround for DNS based rejection lists that
-		fail for AAAA queries.  Problem noted by Chris Boyd.
-	CONFIG: Accept the machine's hostname as resolvable when checking
-		the sender address.  This allows locally submitted mail to
-		be accepted if the machine isn't connected to a nameserver
-		and doesn't have an /etc/hosts entry for itself.  Problem
-		noted by Robert Watson of the TrustedBSD Project.
-	CONFIG: Use deferred expansion for checking the ${deliveryMode}
-		macro in case the SMTP VERB command is used.  Problem
-		noted by Bryan Costales.
-	CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no
-		matches are found.  Fix from Andrzej Filip.
-	CONFIG: Fix wording in default dnsbl rejection message.  Suggested

-	DEVTOOLS: Add new option for access mode of statistics file,
-		confSTMODE, which specifies the permissions when initially
-		installing the sendmail statistics file.
-	LIBMILTER: Mark the listening socket as close-on-exec in case
-		a user's filter starts other applications.
-	LIBSM: Allow the MBDB initialize, lookup, and/or terminate
-		functions in SmMbdbTypes to be set to NULL.
-	MAKEMAP: Change the default file permissions for new databases from
-		0644 to 0640.  This can be overridden at compile time
-		by setting the DBMMODE macro.
-	SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR.

-
-8.12.3/8.12.3	2002/04/05
-	NOTICE: In general queue files should not be moved if queue groups
-		are used.  In previous versions this could cause mail
-		not to be delivered if a queue file is repeatedly moved
-		by an external process whenever sendmail moved it back
-		into the right place.  Some precautions have been taken
-		to avoid moving queue files if not really necessary.
-		sendmail may use links to refer to queue files and it
-		may store the path of data files in queue files.  Hence
-		queue files should not be moved unless those internals
-		are understood and the integrity of the files is not
-		compromised.  Problem noted by Anne Bennett of Concordia
-		University.
-	If an error mail is created, and the mail is split across different
-		queue directories, and SuperSafe is off, then write the mail
-		to disk before splitting it, otherwise an assertion is
-		triggered.  Problem tracked down by Henning Schmiedehausen
-		of INTERMETA.
-	Fix possible race condition that could cause sendmail to forget
-		running queues.  Problem noted by Jeff Wasilko of smoe.org.
-	Handle bogus qf files better without triggering assertions.
-		Problem noted by Guy Feltin.
-	Protect against interrupted select() call when enforcing Milter
-		read and write timeouts.  Patch from Gurusamy Sarathy of
-		ActiveState.
-	Matching queue IDs with -qI should be case sensitive.  Problem
-		noted by Anne Bennett of Concordia University.
-	If privileges have been dropped, don't try to change group ID to
-		the RunAsUser group.  Problem noted by Neil Rickert of
-		Northern Illinois University.
-	Fix SafeFileEnvironment path munging when the specified path
-		contains a trailing slash.  Based on patch from Dirk Meyer
-		of Dinoex.
-	Do not limit sendmail command line length to SM_ARG_MAX (usually
-		4096).  Problem noted by Allan E Johannesen of Worcester
-		Polytechnic Institute.
-	Clear full name of sender for each new envelope to avoid bogus data
-		if several mails are sent in one session and some of them
-		do not have a From: header.  Problem noted by Bas Haakman.
-	Change timeout check such that cached information about a connection
-		will be immediately invalid if ConnectionCacheTimeout is zero.
-		Based on patch from David Burns of Portland State University.
-	Properly count message size for mailstats during mail collection.
-		Problem noted by Werner Wiethege.
-	Log complete response from LMTP delivery agent on failure.  Based on

-		a milter filter and buffered file I/O is being used.
-		Problem noted by Sergey Akhapkin of Dr.Web.
-	Do not honor SIGUSR1 requests if running with extra privileges.
-		Problem noted by Werner Wiethege.
-	Prevent a file descriptor leak on mail delivery if the initial
-		connect fails and DialDelay is set.  Patch from Servaas
-		Vandenberghe of Katholieke Universiteit Leuven.
-	Properly deal with a case where sendmail is called by root running
-		a set-user-ID (non-root) program.  Problem noted by Jon
-		Lusky of ISS Atlanta.
-	Avoid leaving behind stray transcript (xf) files if multiple queue
-		directories are used and mail is sent to a mailing list
-		which has an owner- alias.  Problem noted by Anne Bennett
-		of Concordia University.
-	Fix class map parsing code if optional key is specified.  Problem
-		found by Mario Nigrovic.
-	The SMTP daemon no longer tries to fix up improperly dot-stuffed
-		incoming messages.  A leading dot is always stripped by the
-		SMTP receiver regardless of whether or not it is followed by
-		another dot.  Problem noted by Jordan Ritter of darkridge.com.
-	Fix corruption when doing automatic MIME 7-bit quoted-printable or
-		base64 encoding to 8-bit text.  Problem noted by Mark
-		Elvers.
-	Correct the statistics gathered for total number of connections.
-		Instead of being the exact same number as the total number
-		of messages (T line in mailstats) it now represents the
-		total number of TCP connections.
-	Be more explicit about syntax errors in addresses, especially
-		non-ASCII characters, and properly create DSNs if necessary.
-		Problem noted by Leena Heino of the University of Tampere.
-	Prevent small timeouts from being lost on slow machines if itimers
-		are used.  Problem noted by Suresh Ramasubramanian.
-	Prevent a race condition on child cleanup for delivery to files.
-		Problem noted by Fletcher Mattox of the University of
-		Texas.
-	Change the SMTP error code for temporary map failures from 421
-		to 451.
-	Do not assume that realloc(NULL, size) works on all OS (this was
-		only done in one place: queue group creation).  Based on
-		patch by Bryan Costales.
-	Initialize Timeout.iconnect in the code to prevent randomly short
-		timeouts.  Problem noted by Bradley Watts of AT&T Canada.
-	Do not try to send a second SMTP QUIT command if the remote
-		responds to a MAIL command with a 421 reply or on I/O
-		errors.  By doing so, the host was marked as having a
-		temporary problem and other mail destined for that host was
-		queued for the next queue run.  Problem noted by Fletcher
-		Mattox of the University of Texas, Allan E Johannesen of
-		Worcester Polytechnic Institute, Larry Greenfield of CMU,
-		and Neil Rickert of Northern Illinois University.
-	Ignore error replies from the SMTP QUIT command (including servers
-		which drop the connection instead of responding to the
-		command).
-	Portability:
-		Check LDAP_API_VERSION to determine if ldap_memfree() is
-			available.
-		Define HPUX10 when building on HP-UX 10.X.  That platform
-			now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR
-			settings.  Patch from Elias Halldor Agustsson of
-			Skyrr.
-		Fix dependency building on Mac OS X and Darwin.  Problem
-			noted by John Beck.
-		Preliminary support for the sparc64 port of FreeBSD 5.0.
-		Add /sbin/sh as an acceptable user shell on HP-UX.  From
-			Rajesh Somasund of Hewlett-Packard.
-	CONFIG: Add FEATURE(`authinfo') to allow a separate database for
-		SMTP AUTH information.  This feature was actually added in
-		8.12.0 but a release note was not included.
-	CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce
-		parameter is set and the LDAP lookup returns a temporary
-		error.
-	CONFIG: Honor FEATURE(`relay_hosts_only') when using
-		FEATURE(`relay_mail_from', `domain').  Problem noted by
-		Krzysztof Oledzki.
-	CONFIG: FEATURE(`msp') now disables any type of alias
-		initialization as aliases are not needed for the MSP.
-	CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp')
-		is in use.  Patch from Andrzej Filip.
-	CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of
-		`localhost' and turns on MX lookups for the SMTP mailers.
-		This will only have an effect if a parameter is specified,
-		i.e., an MX lookup will be performed on the hostname unless
-		it is embedded in square brackets.  Problem noted by
-		Theo Van Dinter of Collective Technologies.
-	CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in
-		submit.cf) to use $TZ for time stamps.  This is a compromise
-		to allow for the proper time zone on systems where the
-		default results in misleading time stamps. That is, syslog
-		time stamps and Date headers on submitted mail will use the
-		user's $TZ setting.  Problem noted by Mark Roth of the
-		University of Illinois at Urbana-Champaign, solution proposed
-		by Neil Rickert of Northern Illinois University.
-	CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID
-		binary.  Adjust local mailer flags accordingly.  Problem
-		noted by John Beck.
-	CONTRIB: Add a warning to qtool.pl to not move queue files around
-		if queue groups are used.
-	CONTRIB: buildvirtuser: Add -f option to force rebuild.
-	CONTRIB: smcontrol.pl: Add -f option to specify control socket.
-	CONTRIB: smcontrol.pl: Add support for 'memdump' command.
-		Suggested by Bryan Costales.
-	DEVTOOLS: Add dependency generation for test programs.
-	LIBMILTER: Remove conversion of port number for the socket
-		structure that is passed to xxfi_connect().  Notice:
-		this fix requires that sendmail and libmilter both have
-		this change; mixing versions may lead to wrong port
-		values depending on the endianness of the involved systems.
-		Problem noted by Gisle Aas of ActiveState.
-	LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but
-		SMFI_REJECT is returned, ignore the custom reply.  Do the
-		same if '5XX' is used and SMFI_TEMPFAIL is returned.
-	LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as
-		required by mfapi.h.  Problem noted by Jose Marcio Martins
-		da Cruz of Ecole Nationale Superieure des Mines de Paris.
-	LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define.  Set
-		this to 1 if your LDAP client libraries include
-		ldap_memfree().
-	LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X
-		and NDBM on systems with the O_EXLOCK open(2) flag.
-	SMRSH: Fix compilation problem on some operating systems.  Problem
-		noted by Christian Krackowizer of schuler technodat GmbH.
-	VACATION: Allow root to operate on user vacation databases.  Based
-		on patch from Greg Couch of the University of California,
-		San Francisco.
-	VACATION: Don't ignore -C option.  Based on patch by Bryan Costales.
-	VACATION: Clarify option usage in the man page.  Problem noted by

-8.12.2/8.12.2	2002/01/13
-	Don't complain too much if stdin, stdout, or stderr are missing
-		at startup, only log an error message.
-	Fix potential problem if an unknown operation mode (character
-		following -b) has been specified.
-	Prevent purgestat from looping even if someone changes the
-		permissions or owner of hoststatus files.  Problem noted
-		by Kari Hurtta of the Finnish Meteorological Institute.
-	Properly record dropped connections in persistent host status.
-		Problem noted by Ulrich Windl of the Universitat
-		Regensburg.
-	Remove newlines from recipients read via sendmail -t to prevent
-		SMTP protocol errors when sending the RCPT command.
-		Problem noted by William D. Colburn of the New Mexico
-		Institute of Mining and Technology.
-	Only log milter body replacements once instead of for each body
-		chunk sent by a filter.  Problem noted by Kari Hurtta of
-		the Finnish Meteorological Institute.
-	In 8.12.0 and 8.12.1, the headers were mistakenly not included in
-		the message size calculation.  Problem noted by Kari Hurtta
-		of the Finnish Meteorological Institute.
-	Since 8.12 no longer forks at the SMTP MAIL command, the daemon
-		needs to collect children status to avoid zombie processes.
-		Problem noted by Chris Adams of HiWAAY Informations Services.
-	Shut down "nullserver" and ETRN-only connections after 25 bad
-		commands are issued.  This makes it consistent with normal
-		SMTP connections.
-	Avoid duplicate logging of milter rejections.  Problem noted by
-		William D. Colburn of the New Mexico Institute of Mining
-		and Technology.
-	Error and delay DSNs were being sent to postmaster instead of the
-		message sender if the sender had used a deprecated RFC822
-		source route.  Problem noted by Kari Hurtta of the Finnish
-		Meteorological Institute.
-	Fix FallbackMXhost behavior for temporary errors during address
-		parsing.  Problem noted by Jorg Bielak from Coastal Web
-		Online.
-	For systems on which stat(2) does not return a value for st_blksize
-		that is the "optimal blocksize for I/O" three new compile
-		time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF,
-		and SM_IO_MAX_BUF, which define an upper limit for
-		regular files, and a lower and upper limit for other file
-		types, respectively.
-	Fix a potential deadlock if two events are supposed to occur at
-		exactly the same time.  Problem noted by Valdis Kletnieks
-		of Virginia Tech.
-	Perform envelope splitting for aliases listed directly in the
-		alias file, not just for include/.forward files.
-		Problem noted by John Beck of Sun Microsystems.
-	Allow selection of queue group for mailq using -qGgroup.
-		Based on patch by John Beck of Sun Microsystems.
-	Make sure cached LDAP connections used my multiple maps in the same
-		process are closed.  Patch from Taso N. Devetzis.
-	If running as root, allow reading of class files in protected
-		directories.  Patch from Alexander Talos of the University
-		of Vienna.
-	Correct a few LDAP related memory leaks.  Patch from David Powell
-		of Sun Microsystems.
-	Allow specification of an empty realm via the authinfo ruleset.
-		This is necessary to interoperate as an SMTP AUTH client
-		with servers that do not support realms when using
-		CRAM-MD5.  Problem noted by Bjoern Voigt of TU Berlin.
-	Avoid a potential information leak if AUTH PLAIN is used and the
-		server gets stuck while processing that command.  Problem
-		noted by Chris Adams from HiWAAY Informations Services.
-	In addition to printing errors when parsing recipients during
-		command line invocations log them to make it simpler
-		to understand possible DSNs to postmaster.
-	Do not use FallbackMXhost on mailers which have the F=0 flag set.
-	Allow local mailers (F=l) to specify a host for TCP connections
-		instead of forcing localhost.
-	Obey ${DESTDIR} for installation of the client mail queue and
-		submit.cf.  Patch from Peter 'Luna' Runestig.
-	Re-enable support for -M option which was broken in 8.12.1.  Problem
-		noted by Neil Rickert of Northern Illinois University.
-	If a remote server violates the SMTP standard by unexpectedly
-		dropping the connection during an SMTP transaction, stop
-		sending commands.  This prevents bogus "Bad file number"
-		recipient status.  Problem noted by Allan E Johannesen of
-		Worcester Polytechnic Institute.
-	Do not use a size estimate of 100 for postmaster bounces, it's
-		almost always too small; do not guess the size at all.
-	New VENDOR_DEC for Compaq/DEC.  Requested by James Seagraves of
-		Compaq Computer Corp.
-	Fix DaemonPortOptions IPv6 address parsing such that ::1 works
-		properly.  Problem noted by Valdis Kletnieks of Virginia
-		Tech.
-	Portability:
-		Fix IPv6 network interface probing on HP-UX 11.X.  Based on

-			Sachin of Siemens.
-		Set SM_IO_MIN_BUF (4K) and SM_IO_MAX_BUF (8K) for HP-UX.
-		Reduce optimization from +O3 to +O2 on HP-UX 11.  This
-			fixes a problem that caused additional bogus
-			characters to be written to the qf file.  Problem
-			noted by Tapani Tarvainen.
-		Set LDA_USE_LOCKF by default for UnixWare.  Problem noted
-			by Boyd Lynn Gerber.
-		Add support for HP MPE/iX.  See sendmail/README for port
-			information.  From Mark Bixby of Hewlett-Packard.
-		New portability defines HASNICE, HASRRESVPORT, USE_ENVIRON,

-8.12.1/8.12.1	2001/10/01
-	SECURITY: Check whether dropping group privileges actually succeeded
-		to avoid possible compromises of the mail system by
-		supplying bogus data.  Add configuration options for
-		different set*gid() calls to reset saved gid.  Problem
-		found by Michal Zalewski.
-	PRIVACY: Prevent information leakage when sendmail has extra
-		privileges by disabling debugging (command line -d flag)
-		during queue runs and disabling ETRN when sendmail -bs is
-		used.  Suggested by Michal Zalewski.
-	Avoid memory corruption problems resulting from bogus .cf files.
-		Problem found by Michal Zalewski.
-	Set the ${server_addr} macro to name of mailer when doing LMTP
-		delivery.  LMTP systems may offer SMTP Authentication or
-		STARTTLS causing sendmail to use this macro in rulesets.
-	If debugging is turned on (-d0.10) print not just the default
-		values for configuration file and pid file but also the
-		selected values.  Problem noted by Brad Chapman.
-	Continue dealing with broken nameservers by ignoring SERVFAIL
-		errors returned on T_AAAA (IPv6) lookups at delivery time
-		if ResolverOptions=WorkAroundBrokenAAAA is set.  Previously
-		this only applied to hostname canonification.  Problem
-		noted by Bill Fenner of AT&T Research.
-	Ignore comments in NIS host records when trying to find the
-		canonical name for a host.
-	When sendmail has extra privileges, limit mail submission command
-		line flags (i.e., -G, -h, -F, etc.)  to mail submission
-		operating modes (i.e., -bm, -bs, -bv, etc.).  Idea based on
-		suggestion from Michal Zalewski.
-	Portability:
-		AIX: Use `oslevel` if available to determine OS version.

-		OpenUNIX: Use lockf() for LDA delivery (affects mail.local).
-			Problem noticed by Boyd Lynn Gerber of ZENEX.
-		Avoid compiler warnings by not using pointers to pass
-			integers.  Problem noted by Todd C. Miller of
-			Courtesan Consulting.
-	CONFIG: Add restrictqrun to PrivacyOptions for the MSP to minimize

-8.12.0/8.12.0	2001/09/08
-	*NOTICE*: The default installation of sendmail does not use
-		set-user-ID root anymore.  You need to create a new user and
-		a new group before installing sendmail (both called smmsp by
-		default).  The installation process tries to install
-		/etc/mail/submit.cf and creates /var/spool/clientmqueue by
-		default.  Please see sendmail/SECURITY for details.
-	SECURITY: Check for group and world writable forward and :include:
-		files.  These checks can be turned off if absolutely
-		necessary using the DontBlameSendmail option and the new
-		flags:
-			GroupWritableForwardFile
-			WorldWritableForwardFile
-			GroupWritableIncludeFile
-			WorldWritableIncludeFile
-		Problem noted by Slawek Zak of Politechnika Warszawska,
-	SECURITY: Drop privileges when using address test mode.  Suggested
-		by Michal Zalewski of the "Internet for Schools" project
-		(IdS).
-	Fixed problem of a global variable being used for a timeout jump
-		point where the variable could become overused for more than
-		one timeout concurrently.  This erroneous behavior resulted in
-		a corrupted stack causing a core dump.  The timeout is now
-		handled via libsm.  Problem noted by Michael Shapiro,
-		John Beck, and Carl Smith of Sun Microsystems.
-	If sendmail is set-group-ID then that group ID is used for permission
-		checks (group ID of RunAsUser).  This allows use of a
-		set-group-ID sendmail binary for initial message submission
-		and no set-user-ID root sendmail is needed.  For details
-		see sendmail/SECURITY.
-	Log a warning if a non-trusted user changes the syslog label.
-		Based on notice from Bryan Costales of SL3D, Inc.
-	If sendmail is called for initial delivery, try to use submit.cf
-		with a fallback of sendmail.cf as configuration file.  See
-		sendmail/SECURITY.
-	New configuration file option UseMSP to allow group writable queue
-		files if the group is the same as that of a set-group-ID
-		sendmail binary.  See sendmail/SECURITY.
-	The .cf file is chosen based on the operation mode. For -bm (default),
-		-bs, and -t it is submit.cf if it exists for all others it
-		is sendmail.cf (to be backward compatible).  This selection
-		can be changed by the new option -Ac or -Am (alternative .cf
-		file: client or mta).  See sendmail/SECURITY.
-	The SMTP server no longer forks on each MAIL command.  The ONEX
-		command has been removed.
-	Implement SMTP PIPELINING per RFC 2920.  It can be turned off
-		at compile time or per host (ruleset).
-	New option MailboxDatabase specifies the type of mailbox database
-		used to look up local mail recipients; the default value
-		is "pw", which means to use getpwnam().  New mailbox database
-		types can be added by adding custom code to libsm/mbdb.c.
-	Queue file names are now 15 characters long, rather than 14 characters
-		long, to accomodate envelope splitting.  File systems with
-		a 14 character file name length limit are no longer
-		supported.
-	Recipient list used for delivery now gets internally ordered by
-		hostsignature (character string version of MX RR).  This orders
-		recipients for the same MX RR's together meaning smaller
-		portions of the list need to be scanned (instead of the whole
-		list) each delivery() pass to determine piggybacking.  The
-		significance of the change is better the larger the recipient
-		list.  Hostsignature is now created during recipient list
-		creation rather than just before delivery.
-	Enhancements for more opportunistic piggybacking.  Previous
-		piggybacking (called coincidental) extended to coattail
-		piggybacking.  Rather than complete MX RR matching
-		(coincidental) piggybacking is done if just the lowest value
-		preference matches (coattail).
-	If sendmail receives a temporary error on a RCPT TO: command, it will
-		try other MX hosts if available.
-	DefaultAuthInfo can contain a list of mechanisms to be used for
-		outgoing (client-side) SMTP Authentication.
-	New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable
-		AUTH (overrides 'a' modifier in DaemonPortOptions).  Based
-		on patch from Lyndon Nerenberg of Messaging Direct.
-	Enable AUTH mechanism EXTERNAL if STARTTLS is used.
-	A new ruleset authinfo can be used to return client side
-		authentication information for AUTH instead of DefaultAuthInfo.
-		Therefore the DefaultAuthInfo option is deprecated and will be
-		removed in future versions.
-	Accept any SMTP continuation code 3xy for AUTH even though RFC 2554
-		requires 334.  Mercury 1.48 is a known offender.
-	Add new option AuthMaxBits to limit the overall encryption strength
-		for the security layer in SMTP AUTH (SASL).  See
-		doc/op/op.me for details.
-	Introduce new STARTTLS related macros {cn_issuer}, {cn_subject},
-		{cert_md5} which hold the CN (common name) of the CA that
-		signed the presented certificate, the CN and the MD5 hash
-		of the presented certificate, respectively.
-	New ruleset try_tls to decide whether to try (as client) STARTTLS.
-	New ruleset srv_features to enable/disable certain features in the
-		server per connection.  See doc/op/op.me for details.
-	New ruleset tls_rcpt to decide whether to send e-mail to a particular
-		recipient; useful to decide whether a conection is secure
-		enough on a per recipient basis.
-	New option TLSSrvOptions to modify some aspects of the server
-		for STARTTLS.
-	If no certificate has been requested, the macro {verify} has the
-		value "NOT".
-	New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off
-		using/offering STARTTLS when delivering/receiving e-mail.
-	Macro expand filenames/directories for certs and keys in the .cf file.
-		Proposed by Neil Rickert of Northern Illinois University.
-	Generate an ephemeral RSA key for a STARTTLS connection only if
-		really required.  This change results in a noticable
-		performance gains on most machines.  Moreover, if shared
-		memory is in use, reuse the key several times.
-	Add queue groups which can be used to group queue directories with
-		the same behavior together.  See doc/op/op.me for details.
-	If the new option FastSplit (defaults to one) has a value greater
-		than zero, it suppresses the MX lookups on addresses when they
-		are initially sorted which may result in faster envelope
-		splitting.  If the mail is submitted directly from the
-		command line, then the value also limits the number of
-		processes to deliver the envelopes; if more envelopes are
-		created they are only queued up and must be taken care of
-		by a queue run.
-	The check for 'enough disk space' now pays attention to which file
-		system each queue directory resides in.
-	All queue runners can be cleanly terminated via SIGTERM to parent.
-	New option QueueFileMode for the default permissions of queue files.
-	Add parallel queue runner code.  Allows multiple queue runners per work
-		group (one or more queues in a multi-queue environment
-		collected together) to process the same work list at the
-		same time.
-	Option MaxQueueChildren added to limit the number of concurrently
-		active queue runner processes.
-	New option MaxRunnersPerQueue to specify the maximum number of queue
-		runners per queue group.
-	Queue member selection by substring pattern matching now allows
-		the pattern to be negated.  For -qI, -qR and -qS it is
-		permissible for -q!I, -q!R and -q!S to mean remove members
-		of the queue that match during processing.
-	New -qp[time] option is similar to -qtime, except that instead of
-		periodically forking a child to process the queue, a single
-		child is forked for each queue that sleeps between queue
-		runs.  A SIGHUP signal can be sent to restart this
-		persistent queue runner.
-	The SIGHUP signal now restarts a timed queue run process (i.e., a
-		sendmail process which only runs the queue at an interval:
-		sendmail -q15m).
-	New option NiceQueueRun	to set the priority of queue runners.
-		Proposed by Thom O'Connor.
-	sendmail will run the queue(s) in the background when invoked with -q
-		unless the new -qf option or -v is used.
-	QueueSortOrder=Random sorts the queue randomly, which is useful if
-		several queue runners are started by hand to avoid contention.
-	QueueSortOrder=Modification sorts the queue by the modification time
-		of the qf file (older entries first).
-	Support Deliver By SMTP Service Extension (RFC 2852) which allows
-		a client to specify an amount of time within which an e-mail
-		should be delivered.  New option DeliverByMin added to set the
-		minimum amount of time or disable the extension.
-	Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are
-		not allowed unless escaped or quoted.
-	Add support for a generic DNS map.  Based on a patch contributed
-		by Leif Johansson of Stockholm University, which was based on
-		work by Assar Westerlund of Swedish Institute of Computer
-		Science, Kista, and Johan Danielsson of Royal Institute of
-		Technology, Stockholm, Sweden.
-	MX records will be looked up for FallBackMXhost.  To use the old
-		behavior (no MX lookups), put the name in square brackets.
-		Proposed by Thom O'Connor.
-	Use shared memory to store free space of filesystems that are used
-		for queues, if shared memory is available and if a key is set
-		via SharedMemoryKey.  This minimizes the number of system
-		calls to check the available space.  See doc/op/op.me for
-		details.
-	If shared memory is compiled in the option -bP can be used to print
-		the number of entries in the queue(s).
-	Enable generic mail filter API (milter).  See libmilter/README
-		and the usual documentation for details.
-	Remove AutoRebuildAliases option, deprecated since 8.10.
-	Remove '-U' (initial user submission) command line option as
-		announced in 8.10.
-	Remove support for non-standard SMTP command XUSR.  Use an MSA instead.
-	New macro {addr_type} which contains whether the current address is
-		an envelope sender or recipient address.  Suggested by
-		Neil Rickert of Northern Illinois University.
-	Two new options for host maps: -d (retransmission timeout),
-		-r (number of retries).
-	New option for LDAP maps: the -V<sep> allows you to specify a
-		separator such that a lookup can return both an attribute
-		and value separated by the given separator.
-	Add new operators '%', '|', '&' (modulo, binary or, binary and)
-		to map class arith.
-	If DoubleBounceAddress expands to an empty string, ``double bounces''
-		(errors that occur when sending an error message) are dropped.
-	New DontBlameSendmail options GroupReadableSASLDBFile and
-		GroupWritableSASLDBFile to relax requirements for sasldb files.
-	New DontBlameSendmail options GroupReadableKeyFile to relax
-		requirements for files containing secret keys.  This is
-		necessary for the MSP if client authentification is used.
-	Properly handle quoted filenames for class files (to allow for
-		filenames with spaces).
-	Honor the resolver option RES_NOALIASES when canonifying hostnames.
-	Add macros to avoid the reuse of {if_addr} etc:
-		{if_name_out}	hostname of interface of outgoing connection.
-		{if_addr_out}	address of interface of outgoing connection.
-		{if_family_out}	family of interface of outgoing connection.
-		The latter two are only set if the interface does not belong
-		to the loopback net.
-	Add macro {nrcpts} which holds the number of (validated) recipients.
-	DialDelay option applies only to mailers with flag 'Z'.  Patch from
-		Juergen Georgi of RUS University of Stuttgart.
-	New Timeout.lhlo,auth,starttls options to limit the time waiting for
-		an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command.
-	New Timeout.aconnect option to limit the overall waiting time for
-		all connections for a single delivery attempt to succeed.
-	Limit the rate recipients in the SMTP envelope are accepted once
-		a threshold number of recipients has been rejected (option
-		BadRcptThrottle).  From Gregory A Lundberg of the WU-FTPD
-		Development Group.
-	New option DelayLA to delay connections if the load averages
-		exceeds the specified value.  The default of 0 does not
-		change the previous behavior.  A value greater than 0
-		will cause sendmail to sleep for one second on most
-		SMTP commands and before accepting connections if that
-		load average is exceeded.
-	Use a dynamic (instead of fixed-size) buffer for the list of
-		recipients that are sent during a connection to a mailer.
-		This also introduces a new mailer field 'r' which defines
-		the maximum number of recipients (defaults to 100).
-		Based on patch by Motonori Nakamura of Kyoto University.
-	Add new F=1 mailer flag to disable sending of null characters ('\0').
-	Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead.
-	The deprecated [TCP] builtin mailer pathname (P=) is gone.  Use [IPC]
-		instead.
-	IPC is no longer available as first mailer argument (A=) for [IPC]
-		builtin mailer pathnames.  Use TCP instead.
-	PH map code updated to use the new libphclient API instead of the
-		old libqiapi library.  Contributed by Mark Roth of the
-		University of Illinois at Urbana-Champaign.
-	New option DirectSubmissionModifiers to define {daemon_flags}
-		for direct (command line) submissions.
-	New M=O modifier for DaemonPortOptions to ignore the socket in
-		case of failures.  Based on patch by Jun-ichiro itojun
-		Hagino of the KAME Project.
-	Add Disposition-Notification-To: (RFC 2298) to the list of headers
-		whose content is rewritten similar to Reply-To:.
-		Proposed by Andrzej Filip.
-	Use STARTTLS/AUTH=server/client for logging incoming/outgoing
-		STARTTLS/AUTH connections; log incoming connections at level
-		9 or higher.  Use AUTH/STARTTLS instead of SASL/TLS for SMTP
-		AUTH/STARTTLS related logfile entries.
-	Convert unprintable characters (and backslash) into octal or C format
-		before logging.
-	Log recipients if no message is transferred but QUIT/RSET is given
-		(at LogLevel 9/10 or higher).
-	Log discarded recipients at LogLevel 10 or higher.
-	Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections
-		in which most commands are rejected due to check_relay or
-		TCP Wrappers if the host tries one of those commands anyway.
-	Change logging format for cloned envelopes to be similar to that for
-		DSNs ("old id: new id: clone").  Suggested by Ulrich Windl
-		of the Universitat Regensburg.
-	Added libsm, a C library of general purpose abstractions including
-		assertions, tracing and debugging with named debug categories,
-		exception handling, malloc debugging, resource pools,
-		portability abstractions, and an extensible buffered I/O
-		package.  It will at some point replace libsmutil.
-		See libsm/index.html for details.
-	Fixed most memory leaks in sendmail which were previously taken
-		care of by fork() and exit().
-	Use new sm_io*() functions in place of stdio calls.  Allows for
-		more consistent portablity amongst different platforms
-		new and old (from new libsm).
-	Common I/O pkg means just one buffering method needed instead of two
-		('bf_portable' and 'bf_torek' now just 'bf').
-	Sfio no longer needed as SASL/TLS code uses sm_io*() API's.
-	New possible value 'interactive' for SuperSafe which can be used
-		together with DeliveryMode=interactive is to avoid some disk
-		synchronizations calls.
-	Add per-recipient status information to mailq -v output.
-	T_ANY queries are no longer used by sendmail.
-	When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS"
-		too (see include/sm/cdefs.h for more info).
-	sendmail -d now has general support for named debug categories.
-		See libsm/debug.html and section 3.4 of doc/op/op.me
-		for details.
-	Eliminate the "postmaster warning" DSNs on address parsing errors
-		such as unbalanced angle brackets or parentheses.  The DSNs
-		generated by this condition were illegal (not RFC conform).
-		Problem noted by Ulrich Windl of the Universitaet Regensburg.
-	Do not issue a DSN if the ruleset localaddr resolves to the $#error
-		mailer and the recipient has hence been rejected during the
-		SMTP dialogue.  Problem reported by Larry Greenfield of CMU.
-	Deal with a case of multiple deliveries on misconfigured systems
-		that do not have postmaster defined.  If an email was sent
-		from an address to which a DSN cannot be returned and
-		in which at least one recipient address is non-deliverable,
-		then that email had been delivered in each queue run.
-		Problem reported by Matteo HCE Valsasna of Universita
-		degli Studi dell'Insubria.
-	The compilation options SMTP, DAEMON, and QUEUE have been removed,
-		i.e., the corresponding code is always compiled in now.
-	Log the command line in daemon/queue-run mode at LogLevel 10 and
-		higher.  Suggested by Robert Harker of Harker Systems.
-	New ResolverOptions setting: WorkAroundBrokenAAAA.  When
-		attempting to canonify a hostname, some broken nameservers
-		will return SERVFAIL (a temporary failure) on T_AAAA (IPv6)
-		lookups.  If you want to excuse this behavior, use this new
-		flag.  Suggested by Chris Foote of SE Network Access and
-		Mark Roth of the University of Illinois at
-		Urbana-Champaign.
-	Free the memory allocated by getipnodeby{addr,name}().  Problem
-		noted by Joy Latten of IBM.
-	ConnectionRateThrottle limits the number of connections per second
-		to each daemon individually, not the overall number of
-		connections.
-	Specifying only "ldap:" as an AliasFile specification will force
-		sendmail to use a default alias schema as outlined in the
-		``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of
-		cf/README.
-	Add a new syntax for the 'F' (file class) sendmail.cf command.  If
-		the first character after the class name is not a '/' or a
-		'|' and it contains an '@' (e.g., F{X}key@class:spec), the
-		rest of the line will be parsed as a map lookup.  This
-		allows classes to be filled via a map lookup.  See op.me
-		for more syntax information.  Specifically, this can be
-		used for commands such as VIRTUSER_DOMAIN_FILE() to read
-		the list of domains via LDAP (see the ``USING LDAP FOR
-		ALIASES, MAPS, and CLASSES'' section of cf/README for an
-		example).
-	The new macro ${sendmailMTACluster} determines the LDAP cluster for
-		the default schema used in the above two items.
-	Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a
-		warning if a program being run from a mailer or file class
-		(e.g., F|/path/to/prog) is in an unsafe directory path.
-	Unless DontBlameSendmail=RunWritableProgram is set, log a warning
-		if a program being run from a mailer or file class
-		(e.g., F|/path/to/prog) is group or world writable.
-	Loopback interfaces (e.g., "lo0") are now probed for class {w}
-		hostnames.  Setting DontProbeInterfaces to "loopback"
-		(without quotes) will disable this and return to the
-		pre-8.12 behavior of only probing non-loopback interfaces.
-		Suggested by Bryan Stansell of GNAC.
-	In accordance with RFC 2821 section 4.1.4, accept multiple
-		HELO/EHLO commands.
-	Multiple ClientPortOptions settings are now allowed, one for each
-		possible protocol family which may be used for outgoing
-		connections.  Restrictions placed on one family only affect
-		outgoing connections on that particular family.  Because of
-		this change, the ${client_flags} macro is not set until the
-		connection is established.  Based on patch from Motonori
-		Nakamura of Kyoto University.
-	PrivacyOptions=restrictexpand instructs sendmail to drop privileges
-		when the -bv option is given by users who are neither root
-		nor the TrustedUser so users can not read private aliases,
-		forwards, or :include: files.  It also will override the -v
-		(verbose) command line option.
-	If the M=b modifier is set in DaemonPortOptions and the interface
-		address can't be used for the outgoing connection, fall
-		back to the settings in ClientPortOptions (if set).
-		Problem noted by John Beck of Sun Microsystems.
-	New named config file rule check_data for DATA command (input:
-		number of recipients).  Based on patch from Mark Roth of
-		the University of Illinois at Urbana-Champaign.
-	Add support for ETRN queue selection per RFC 1985.  The queue group
-		can be specified using the '#' option character.  For
-		example, 'ETRN #queuegroup'.
-	If an LDAP server times out or becomes unavailable, close the
-		current connection and reopen to get to one of the fallback
-		servers.  Patch from Paul Hilchey of the University of
-		British Columbia.
-	Make default error number on $#error messages 550 instead of 501
-		because 501 is not allowed on all commands.
-	The .cf file option UnsafeGroupWrites is deprecated, it should be
-		replaced with the settings GroupWritableForwardFileSafe
-		and GroupWritableIncludeFileSafe in DontBlameSendmail
-		if required.
-	The deprecated ldapx map class has been removed.  Use the ldap map
-		class instead.
-	Any IPv6 addresses used in configuration should be prefixed by the
-		"IPv6:" tag to identify the address properly.  For example,
-		if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to
-		class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4].
-	Change the $&{opMode} macro if the operation mode changes while the
-		MTA is running.  For example, during a queue run.
-	Add "use_inet6" as a new ResolverOptions flag to control the
-		RES_USE_INET6 resolver option.  Based on patch from Rick
-		Nelson of IBM.
-	The maximum number of commands before the MTA slows down when too
-		many "light weight" commands have been received are now
-		configurable during compile time.  The current values and
-		their defaults are:
-		    MAXBADCOMMANDS	25	unknown commands
-		    MAXNOOPCOMMANDS	20	NOOP, VERB, ONEX, XUSR
-		    MAXHELOCOMMANDS	3	HELO, EHLO
-		    MAXVRFYCOMMANDS	6	VRFY, EXPN
-		    MAXETRNCOMMANDS	8	ETRN
-		Setting a value to 0 disables the check.  Patch from Bryan
-		Costales of SL3D, Inc.
-	The header syntax H?${MyMacro}?X-My-Header: now not only checks if
-		${MyMacro} is defined but also that it is not empty.
-	Properly quote usernames with special characters if they are used
-		in headers.  Problem noted by Kari Hurtta of the Finnish
-		Meteorological Institute.
-	Be sure to include the proper Final-Recipient: DSN header in bounce
-		messages for messages for mailing list expanded addresses
-		which are not delivered on the initial attempt.
-	Do not treat errors as sticky when doing delivery via LMTP after
-		the final dot has been sent to avoid affecting future
-		deliveries.  Problem reported by Larry Greenfield of CMU.
-	New compile time flag REQUIRES_DIR_FSYNC which turns on support for
-		file systems that require to call fsync() for a directory
-		if the meta-data in it has been changed.  This should be
-		set at least for ReiserFS; it is enabled by default for Linux.
-		See sendmail/README for further information.
-	Avoid file locking deadlock when updating the statistics file if
-		sendmail is signaled to terminate.  Problem noted by
-		Christophe Wolfhugel of France Telecom.
-	Set the $c macro (hop count) as it is being set instead of when the
-		envelope is initialized.  Problem noted by Kari Hurtta of
-		the Finnish Meteorological Institute.
-	Properly count recipients for DeliveryMode defer and queue.  Fix
-		from Peter A. Friend of EarthLink.
-	Treat invalid hesiod lookups as permanent errors instead of
-		temporary errors.  Problem noted by Russell McOrmond of
-		flora.ca.
-	Portability:
-		Remove support for AIX 2, which supports only 14 character
-			filenames and is outdated anyway.  Suggested by
-			Valdis Kletnieks of Virginia Tech.
-		Change several settings for Irix 6: remove confSBINDIR,
-			i.e., use default /usr/sbin, change owner/group
-			of man pages and user-executable to root/sys, set
-			optimization limit to 0 (unlimited).  Based on patch
-			from Ayamura Kikuchi, M.D, and proposal from Kari
-			Hurtta of the Finnish Meteorological Institute.
-		Do not assume LDAP support is installed by default under
-			Solaris 8 and later.
-		Add support for OpenUNIX.
-	CONFIG: Increment version number of config file to 10.
-	CONFIG: Add an install target and a README file in cf/cf.
-	CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc.
-	CONFIG: Reject empty recipient addresses (in check_rcpt).
-	CONFIG: The access map uses an option of -T<TMPF> to deal with
-		temporary lookup failures.
-	CONFIG: New value for access map: SKIP, which causes the default
-		action to be taken by aborting the search for domain names
-		or IP nets.
-	CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or
-		relay address as long as the other part allows the email
-		to get through.
-	CONFIG: Entries for virtusertable can make use of a third parameter
-		"%3" which contains "+detail" of a wildcard match, i.e., an
-		entry like user+*@domain.  This allows handling of details by
-		using %1%3 as the RHS.  Additionally, a "+" wildcard has been
-		introduced to match only non-empty details of addresses.
-	CONFIG: Numbers for rulesets used by MAILERs have been removed
-		and hence there is no required order within the MAILER
-		section anymore except for MAILER(`uucp') which must come
-		after MAILER(`smtp') if uucp-dom and uucp-uudom are used.
-	CONFIG: Hosts listed in the generics domain class {G}
-		(GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated
-		as canonical.  Suggested by Per Hedeland of Ericsson.
-	CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup
-		in the access map which returns OK or RELAY actually
-		terminates check_* ruleset checking.
-	CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset
-		tls_rcpt, see cf/README for details.
-	CONFIG: Change format of Received: header line which reveals whether
-		STARTTLS has been used to "(version=${tls_version}
-		cipher=${cipher} bits=${cipher_bits} verify=${verify})".
-	CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks')
-		options friends/haters instead of "To:" and enable
-		specification of whole domains instead of just users.
-		Notice: this change is not backward compatible.
-		Suggested by Chris Adams from HiWAAY Informations Services.
-	CONFIG: Allow for local extensions for most new rulesets, see
-		cf/README for details.
-	CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in
-		the access map.  Proposed by Randall Winchester of the
-		University of Maryland.
-	CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for
-		the local mailer.  Proposed by Ingo Brueckl of Wupper Online.
-	CONFIG: confRELAY_MSG/confREJECT_MSG can override the default
-		messages for an unauthorized relaying attempt/for access
-		map entries with RHS REJECT, respectively.
-	CONFIG: FEATURE(`always_add_domain') takes an optional argument
-		to specify another domain to be added instead of the local one.
-		Suggested by Richard H. Gumpertz of Computer Problem
-		Solving.
-	CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific
-		options, see doc/op/op.me for details.
-	CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for
-		the security layer in SMTP AUTH (SASL).
-	CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated
-		immediately.
-	CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which
-		allows checking of the return values of the DNS lookups.
-		See cf/README for details.
-	CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for
-		temporary lookup failures.
-	CONFIG: New option confDELIVER_BY_MIN to specify minimum time for
-		Deliver By (RFC 2852) or to turn off the extension.
-	CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared
-		memory use.
-	CONFIG: New FEATURE(`compat_check') to look up a key consisting
-		of the sender and the recipient address delimited by the
-		string "<@>", e.g., sender@sdomain<@>recipient@rdomain,
-		in the access map.  Based on code contributed by Mathias
-		Koerber of Singapore Telecommunications Ltd.
-	CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user
-		file.  Suggested by John Beck of Sun Microsystems.
-	CONFIG: Don't use MAILER-DAEMON for error messages delivered
-		via LMTP.  Problem reported by Larry Greenfield of CMU.
-	CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of
-		the recipient host if LUSER_RELAY is used.
-	CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the
-		+detail portion of the address when passing address to
-		local delivery agent.  Disables alias and .forward +detail
-		stripping.  Only use if LDA supports this.
-	CONFIG: Removed deprecated FEATURE(`rbl').
-	CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE()
-		which allow you to specify 'equivalent' hosts for LDAP
-		Routing lookups.  Equivalent hostnames are replaced by the
-		masquerade domain name for lookups.  See cf/README for
-		additional details.
-	CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which
-		instructs the rulesets on what to do if the address being
-		looked up has +detail information.  See cf/README for more
-		information.
-	CONFIG: When chosing a new destination via LDAP Routing, also look
-		up the new routing address/host in the mailertable.  Based
-		on patch from Don Badrak of the United States Census Bureau.
-	CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing
-		is in use and the bounce option is enabled.  Only reject
-		recipients as user unknown.
-	CONFIG: Provide LDAP support for the remaining database map
-		features.  See the ``USING LDAP FOR ALIASES AND MAPS''
-		section of cf/README for more information.
-	CONFIG: Add confLDAP_CLUSTER which defines the ${sendmailMTACluster}
-		macro used for LDAP searches as described above in ``USING
-		LDAP FOR ALIASES, MAPS, AND CLASSES''.
-	CONFIG: confCLIENT_OPTIONS has been replaced by CLIENT_OPTIONS(),
-		which takes the options as argument and can be used
-		multiple times; see cf/README for details.
-	CONFIG: Add configuration macros for new options:
-		confBAD_RCPT_THROTTLE		BadRcptThrottle
-		confDIRECT_SUBMISSION_MODIFIERS	DirectSubmissionModifiers
-		confMAILBOX_DATABASE		MailboxDatabase
-		confMAX_QUEUE_CHILDREN		MaxQueueChildren
-		confMAX_RUNNERS_PER_QUEUE	MaxRunnersPerQueue
-		confNICE_QUEUE_RUN		NiceQueueRun
-		confQUEUE_FILE_MODE		QueueFileMode
-		confFAST_SPLIT			FastSplit
-		confTLS_SRV_OPTIONS		TLSSrvOptions
-		See above (and related documentation) for further information.
-	CONFIG: Add configuration variables for new timeout options:
-		confTO_ACONNECT		Timeout.aconnect
-		confTO_AUTH		Timeout.auth
-		confTO_LHLO		Timeout.lhlo
-		confTO_STARTTLS		Timeout.starttls
-	CONFIG: Add configuration macros for mail filter API:
-		confINPUT_MAIL_FILTERS		InputMailFilters
-		confMILTER_LOG_LEVEL		Milter.LogLevel
-		confMILTER_MACROS_CONNECT	Milter.macros.connect
-		confMILTER_MACROS_HELO		Milter.macros.helo
-		confMILTER_MACROS_ENVFROM	Milter.macros.envfrom
-		confMILTER_MACROS_ENVRCPT	Milter.macros.envrcpt
-		Mail filters can be defined via INPUT_MAIL_FILTER() and
-		MAIL_FILTER().  See libmilter/README, cf/README, and
-		doc/op/op.me for details.
-	CONFIG: Add support for accepting temporarily unresolvable domains.
-		See cf/README for details.  Based on patch by Motonori
-		Nakamura of Kyoto University.
-	CONFIG: confDEQUOTE_OPTS can be used to specify options for the
-		dequote map.
-	CONFIG: New macro QUEUE_GROUP() to define queue groups.
-	CONFIG: New FEATURE(`queuegroup') to select a queue group based
-		on the full e-mail address or the domain of the recipient.
-	CONFIG: Any IPv6 addresses used in configuration should be prefixed
-		by the "IPv6:" tag to identify the address properly.  For
-		example, if you want to use the IPv6 address
-		2002:c0a8:51d2::23f4 in the access database, you would need
-		to use IPv6:2002:c0a8:51d2::23f4 on the left hand side.
-		This affects the access database as well as the
-		relay-domains and local-host-names files.
-	CONFIG: OSTYPE(aux) has been renamed to OSTYPE(a-ux).
-	CONFIG: Avoid expansion of m4 keywords in SMART_HOST.
-	CONFIG: Add MASQUERADE_EXCEPTION_FILE() for reading masquerading
-		exceptions from a file.  Suggested by Trey Breckenridge of
-		Mississippi State University.
-	CONFIG: Add LOCAL_USER_FILE() for reading local users
-		(LOCAL_USER() -- $={L}) entries from a file.
-	CONTRIB: dnsblaccess.m4 is a further enhanced version of enhdnsbl.m4
-		which allows to lookup error codes in the access map.
-		Contributed by Neil Rickert of Northern Illinois University.
-	DEVTOOLS: Add new options for installation of include and library
-		files: confINCGRP, confINCMODE, confINCOWN, confLIBGRP,
-		confLIBMODE, confLIBOWN.
-	DEVTOOLS: Add new option confDONT_INSTALL_CATMAN to turn off
-		installation of the the formatted man pages on operating
-		systems which don't include cat directories.
-	EDITMAP: New program for editing maps as supplement to makemap.
-	MAIL.LOCAL: Mail.local now uses the libsm mbdb package to look up
-		local mail recipients.  New option -D mbdb specifies the
-		mailbox database type.
-	MAIL.LOCAL: New option "-h filename" which instructs mail.local to
-		deliver the mail to the named file in the user's home
-		directory instead of the system mail spool area.  Based on
-		patch from Doug Hardie of the Los Angeles Free-Net.
-	MAILSTATS: New command line option -P which acts the same as -p but
-		doesn't truncate the statistics file.
-	MAKEMAP: Add new option -t to specify a different delimiter
-		instead of white space.
-	RMAIL: Invoke sendmail with '-G' to indicate this is a gateway
-		submission.  Problem noted by Kari Hurtta of the Finnish
-		Meteorological Institute.
-	SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later.
-	VACATION: Change Auto-Submitted: header value from auto-generated to
-		auto-replied.  From Kenneth Murchison of Oceana Matrix Ltd.
-	VACATION: New option -d to send error/debug messages to stdout
-		instead of syslog.
-	VACATION: New option -U which prevents the attempt to lookup login
-		in the password file.  The -f and -m options must be used
-		to specify the database and message file since there is no
-		home directory for the default settings for these options.
-	VACATION: Vacation now uses the libsm mbdb package to look up
-		local mail recipients; it reads the MailboxDatabase option
-		from the sendmail.cf file.  New option -C cffile which
-		specifies the path of the sendmail.cf file.
-	New Directories:

-8.11.7/8.11.7	2003/03/29
-	SECURITY: Fix a remote buffer overflow in header parsing by
-		dropping sender and recipient header comments if the
-		comments are too long.  Problem noted by Mark Dowd
-		of ISS X-Force.
-	SECURITY: Fix a buffer overflow in address parsing due to
-		a char to int conversion problem which is potentially
-		remotely exploitable.  Problem found by Michal Zalewski.
-		Note: an MTA that is not patched might be vulnerable to
-		data that it receives from untrusted sources, which
-		includes DNS.
-	To provide partial protection to internal, unpatched sendmail MTAs,
-		8.11.7 changes by default (char)0xff to (char)0x7f in
-		headers etc.  To turn off this conversion compile with
-		-DALLOW_255 or use the command line option -d82.101.
-	To provide partial protection for internal, unpatched MTAs that may be
-		performing 7->8 or 8->7 bit MIME conversions, the default
-		for MaxMimeHeaderLength has been changed to 2048/1024.
-		Note: this does have a performance impact, and it only
-		protects against frontal attacks from the outside.
-		To disable the checks and return to pre-8.11.7 defaults,
-		set MaxMimeHeaderLength to 0/0.
-	Properly clean up macros to avoid persistence of session data
-		across various connections.  This could cause session
-		oriented restrictions, e.g., STARTTLS requirements,
-		to erroneously allow a connection.  Problem noted
-		by Tim Maletic of Priority Health.
-	Ignore comments in NIS host records when trying to find the
-		canonical name for a host.
-	Fix a memory leak when closing Hesiod maps.
-	Set ${msg_size} macro when reading a message from the command line
-		or the queue.
-	Prevent a segmentation fault when clearing the event list by
-		turning off alarms before checking if event list is
-		empty.  Problem noted by Allan E Johannesen of Worcester
-		Polytechnic Institute.
-	Fix a potential core dump problem if the environment variable
-		NAME is set.  Problem noted by Beth A. Chaney of
-		Purdue University.
-	Prevent a race condition on child cleanup for delivery to files.
-		Problem noted by Fletcher Mattox of the University of
-		Texas.
-	CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce
-		parameter is set and the LDAP lookup returns a temporary
-		error.
-	CONFIG: Fix a syntax error in the try_tls ruleset if
-		FEATURE(`access_db') is not enabled.
-	LIBSMDB: Fix a lock race condition that affects makemap, praliases,
-		and vacation.
-	LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X
-		and NDBM on systems with the O_EXLOCK open(2) flag.
-	MAKEMAP: Avoid going beyond the end of an input line if it does
-		not contain a value for a key.  Based on patch from
-		Mark Bixby from Hewlett-Packard.
-	MAIL.LOCAL: Fix a truncation race condition if the close() on
-		the mailbox fails.  Problem noted by Tomoko Fukuzawa of
-		Sun Microsystems.
-	SMRSH: SECURITY: Only allow regular files or symbolic links to be
-		used for a command.  Problem noted by David Endler of
-		iDEFENSE, Inc.
-
-8.11.6/8.11.6	2001/08/20
-	SECURITY: Fix a possible memory access violation when specifying
-		out-of-bounds debug parameters.  Problem detected by
-		Cade Cairns of SecurityFocus.
-	Avoid leaking recipient information in unrelated DSNs.  This could
-		happen if a connection is aborted, several mails had been
-		scheduled for delivery via that connection, and the timeout
-		is reached such that several DSNs are sent next.  Problem
-		noted by Dileepan Moorkanat of Hewlett-Packard.
-	Fix a possible segmentation violation when specifying too many
-		wildcard operators in a rule.  Problem detected by
-		Werner Wiethege.
-	Avoid a segmentation fault on non-matching Hesiod lookups.  Problem
-		noted by Russell McOrmond of flora.ca
-
-8.11.5/8.11.5	2001/07/31
-	Fix a possible race condition when sending a HUP signal to restart
-		the daemon.  This could terminate the current process without
-		starting a new daemon.  Problem reported by Wolfgang Breyha
-		of SE Netway Communications.
-	Only apply MaxHeadersLength when receiving a message via SMTP or
-		the command line.  Problem noted by Andrey J. Melnikoff.
-	When finding the system's local hostname on an IPv6-enabled system
-		which doesn't have any IPv6 interface addresses, fall back
-		to looking up only IPv4 addresses.  Problem noted by Tim
-		Bosserman of EarthLink.
-	When commands were being rejected due to check_relay or TCP
-		Wrappers, the ETRN command was not giving a response.
-	Incoming IPv4 connections on a Family=inet6 daemon (using
-		IPv4-mapped addresses) were incorrectly labeled as "may be
-		forged".  Problem noted by Per Steinar Iversen of Oslo
-		University College.
-	Shutdown address test mode cleanly on SIGTERM.  Problem noted by
-		Greg King of the OAO Corporation.
-	Restore the original real uid (changed in main() to prevent
-		out of band signals) before invoking a delivery agent.
-		Some delivery agents use this for the "From " envelope
-		"header".  Problem noted by Leslie Carroll of the
-		University at Albany.
-	Mark closed file descriptors properly to avoid reuse. Problem
-		noted by Jeff Bronson of J.D. Bronson, Inc.
-	Setting Timeout options on the command line will also override
-		their sub-suboptions in the .cf file, e.g., -O
-		Timeout.queuereturn=2d will set all queuereturn timeouts
-		to 2 days.  Problem noted by Roger B.A. Klorese.
-	Portability:
-		BSD/OS has a broken setreuid() implementation.  Problem
-			noted by Vernon Schryver of Rhyolite Software.
-		BSD/OS has /dev/urandom(4) (as of version 4.1/199910 ?).
-			Noted by Vernon Schryver of Rhyolite Software.
-		BSD/OS has fchown(2).  Noted by Dave Yadallee of Netline
-			2000 Internet Solutions Inc.
-		Solaris 2.X and later have strerror(3).  From Sebastian
-			Hagedorn of Cologne University.
-	CONFIG: Fix parsing for IPv6 domain literals in addresses
-		(user@[IPv6:address]).  Problem noted by Liyuan Zhou.
-
-8.11.4/8.11.4	2001/05/28
-	Clean up signal handling routines to reduce the chances of heap
-		corruption and other potential race conditions.
-		Terminating and restarting the daemon may not be
-		instantaneous due to this change.  Also, non-root users can
-		no longer send out-of-band signals.  Problem reported by
-		Michal Zalewski of BindView.
-	If LogLevel is greater than 9 and SASL fails to negotiate an
-		encryption layer, avoid core dump logging the encryption
-		strength.  Problem noted by Miroslav Zubcic of Crol.
-	If a server offers "AUTH=" and "AUTH " and the list of mechanisms is
-		different in those two lines, sendmail might not have
-		recognized (and used) all of the offered mechanisms.
-	Fix an IP address lookup problem on Solaris 2.0 - 2.3.  Patch
-		from Kenji Miyake.
-	This time, really don't use the .. directory when expanding
-		QueueDirectory wildcards.
-	If a process is interrupted while closing a map, don't try to close
-		the same map again while exiting.
-	Allow local mailers (F=l) to contact remote hosts (e.g., via
-		LMTP).  Problem noted by Norbert Klasen of the University
-		of Tuebingen.
-	If Timeout.QueueReturn was set to a value less the time it took
-		to write a new queue file (e.g., 0 seconds), the bounce
-		message would be lost.  Problem noted by Lorraine L Goff of
-		Oklahoma State University.
-	Pass map argument vector into map rewriting engine for the regex
-		and prog map types.  Problem noted by Stephen Gildea of
-		InTouch Systems, Inc.
-	When closing an LDAP map due to a temporary error, close all of the
-		other LDAP maps which share the original map's connection
-		to the LDAP server.  Patch from Victor Duchovni of
-		Morgan Stanley.
-	To detect changes of NDBM aliases files check the timestamp of the
-		.pag file instead of the .dir file.  Problem noted by Neil
-		Rickert of Northern Illinois University.
-	Don't treat temporary hesiod lookup failures as permanent.  Patch
-		from Werner Wiethege.
-	If ClientPortOptions is set, make sure to create the outgoing socket
-		with the family set in that option.  Patch from Sean Farley.
-	Avoid a segmentation fault trying to dereference a NULL pointer
-		when logging a MaxHopCount exceeded error with an empty
-		recipient list.  Problem noted by Chris Adams of HiWAAY
-		Internet Services.
-	Fix DSN for "Too many hops" bounces.  Problem noticed by Ulrich
-		Windl of the Universitaet Regensburg.
-	Fix DSN for "mail loops back to me" bounces.  Problem noticed by
-		Kari Hurtta of the Finnish Meteorological Institute.
-	Portability:
-		OpenBSD has a broken setreuid() implementation.
-	CONFIG: Undo change from 8.11.1: change 501 SMTP reply code back
-		to 553 since it is allowed by DRUMS.
-	CONFIG: Add OSTYPE(freebsd4) for FreeBSD 4.X.
-	DEVTOOLS: install.sh did not properly handle paths in the source
-		file name argument.  Noted by Kari Hurtta of the Finnish
-		Meteorological Institute.
-	DEVTOOLS: Add FAST_PID_RECYCLE to compile time options for OpenBSD
-		since it generates random process ids.
-	PRALIASES: Add back adaptive algorithm to deal with different endings
-		of entries in the database (with/without trailing '\0').
-		Patch from John Beck of Sun Microsystems.
-	New Files:
-		cf/ostype/freebsd4.m4
-
-8.11.3/8.11.3	2001/02/27
-	Prevent a segmentation fault when a bogus value was used in the
-		LDAPDefaultSpec option's -r, -s, or -M flags and if a bogus
-		option was used.  Problem noted by Allan E Johannesen of
-		Worcester Polytechnic Institute.
-	Prevent "token too long" message by shortening {currHeader} which
-		could be too long if the last copied character was a quote.
-		Problem detected by Jan Krueger of digitalanswers
-		communications consulting gmbh.
-	Additional IPv6 check for unspecified addresses.  Patch from
-		Jun-ichiro itojun Hagino of the KAME Project.
-	Do not ignore the ClientPortOptions setting if DaemonPortOptions
-		Modifier=b (bind to same interface) is set and the
-		connection came in from the command line.
-	Do not bind to the loopback address if DaemonPortOptions
-		Modifier=b (bind to same interface) is set.  Patch from
-		John Beck of Sun Microsystems.
-	Properly deal with open failures on non-optional maps used in
-		check_* rulesets by returning a temporary failure.
-	Buffered file I/O files were not being properly fsync'ed to disk
-		when they were committed.
-	Properly encode '=' for the AUTH= parameter of the MAIL command.
-		Problem noted by Hadmut Danisch.
-	Under certain circumstances the macro {server_name} could be set
-		to the wrong hostname (of a previous connection), which may
-		cause some rulesets to return wrong results.  This would
-		usually cause mail to be queued up and delivered later on.
-	Ignore F=z (LMTP) mailer flag if $u is given in the mailer A=
-		equate.  Problem noted by Motonori Nakamura of Kyoto
-		University.
-	Work around broken accept() implementations which only partially
-		fill in the peer address if the socket is closed before
-		accept() completes.
-	Return an SMTP "421" temporary failure if the data file can't be
-		opened where the "354" reply would normally be given.
-	Prevent a CPU loop in trying to expand a macro which doesn't exist
-		in a queue run.  Problem noted by Gordon Lack of Glaxo
-		Wellcome.
-	If delivering via a program and that program exits with EX_TEMPFAIL,
-		note that fact for the mailq display instead of just showing
-		"Deferred".  Problem noted by Motonori Nakamura of Kyoto
-		University.
-	If doing canonification via /etc/hosts, try both the fully
-		qualified hostname as well as the first portion of the
-		hostname.  Problem noted by David Bremner of the
-		University of New Brunswick.
-	Portability:
-		Fix a compilation problem for mail.local and rmail if SFIO
-			is in use.  Problem noted by Auteria Wally
-			Winzer Jr. of Champion Nutrition.
-		IPv6 changes for platforms using KAME.  Patch from
-			Jun-ichiro itojun Hagino of the KAME Project.

-		side has sent the final DATA termination dot.  Problem
-		noted by Allan E Johannesen of Worcester Polytechnic
-		Institute.
-	MAIL.LOCAL: If LMTP mode is set, give a temporary error if users
-		are also specified on the command line.  Patch from
-		Motonori Nakamura of Kyoto University.
-	PRALIASES: Skip over AliasFile specifications which aren't based on
-		database files (i.e., only show dbm, hash, and btree).
-	Renamed Files:
-		devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x
-
-8.11.2/8.11.2	2000/12/29
-	Prevent a segmentation fault when trying to set a class in
-		address test mode due to a negative array index.  Audit
-		other array indexing.  This bug is not believed to be
-		exploitable.  Noted by Michal Zalewski of the "Internet for
-		Schools" project (IdS).
-	Add an FFR (for future release) to drop privileges when using
-		address test mode.  This will be turned on in 8.12. It can
-		be enabled by compiling with:
-		APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS')
-		in your devtools/Site/site.config.m4 file.  Suggested by
-		Michal Zalewski of the "Internet for Schools" project (IdS).
-	Fix potential problem with Cyrus-SASL security layer which may have
-		caused I/O errors, especially for mechanism DIGEST-MD5.
-	When QueueSortOrder was set to host, sendmail might not read
-		enough of the queue file to determine the host, making the
-		sort sub-optimal.  Problem noted by Jeff Earickson of
-		Colby College.
-	Don't issue DSNs for addresses which use the NOTIFY parameter (per
-		RFC 1891) but don't have FAILURE as value.
-	Initialize Cyrus-SASL library before the SMTP daemon is started.
-		This implies that every change to SASL related files requires
-		a restart of the daemon, e.g., Sendmail.conf, new SASL
-		mechanisms (in form of shared libraries).
-	Properly set the STARTTLS related macros during a queue run for
-		a cached connection.  Bug reported by Michael Kellen of
-		NxNetworks, Inc.
-	Log the server name in relay= for ruleset tls_server instead of the
-		client name.
-	Include original length of bad field/header when reporting
-		MaxMimeHeaderLength problems.  Requested by Ulrich Windl of
-		the Universitat Regensburg.
-	Fix delivery to set-user-ID files that are expanded from aliases in
-		DeliveryMode queue.  Problem noted by Ric Anderson of the
-		University of Arizona.

-		Jun-ichiro itojun Hagino of the KAME Project.
-	Fix return values for IRIX nsd map.  From Kari Hurtta of the Finnish
-		Meteorological Institute.
-	Fix parsing of DaemonPortOptions and ClientPortOptions.  Read all
-		of the parameters to find Family= setting before trying to
-		interpret Addr= and Port=.  Problem noted by Valdis
-		Kletnieks of Virginia Tech.
-	When delivering to a file directly from an alias, do not call
-		initgroups(); instead use the DefaultUser group information.
-		Problem noted by Marc Schaefer of ALPHANET NF.
-	RunAsUser now overrides the ownership of the control socket, if
-		created.  Otherwise, sendmail can not remove it upon
-		close.  Problem noted by Werner Wiethege.
-	Fix ConnectionRateThrottle counting as the option is the number of
-		overall connections, not the number of connections per
-		socket.  A future version may change this to per socket
-		counting.
-	Portability:
-		Clean up libsmdb so it functions properly on platforms
-			where sizeof(u_int32_t) != sizeof(size_t).  Problem
-			noted by Rein Tollevik of Basefarm AS.

-		patch from Neil Rickert of Northern Illinois University.
-	CONFIG: Change the default DNS based blacklist server for
-		FEATURE(`dnsbl') to blackholes.mail-abuse.org.
-	CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e.,
-		implicitly assume canonical host names.
-	CONFIG: Deal with "::" in IPv6 addresses for access_db.  Based on
-		patch by Motonori Nakamura of Kyoto University.
-	CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of
-		Virginia Tech.
-	CONFIG: Pass the illegal header form <list:;> through untouched
-		instead of making it worse.  Problem noted by Motonori
-		Nakamura of Kyoto University.
-	CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`).
-	CONTRIB: qtool.pl: An empty queue is not an error.  Problem noted
-		by Jan Krueger of digitalanswers communications consulting

-		Roth of the University of Illinois at Urbana-Champaign.
-	DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4
-		variables into bldOS, bldREL, and bldARCH to prevent
-		namespace collisions.  Problem noted by Motonori Nakamura
-		of Kyoto University.
-	RMAIL: Undo the 8.11.1 change to use -G when calling sendmail.  It
-		causes some changes in behavior and may break rmail for
-		installations where sendmail is actually a wrapper to
-		another MTA.  The change will re-appear in a future
-		version.
-	SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X,
-		and SunOS 5.8.  Requested by Jeff A. Earickson of Colby
-		College and John Beck of Sun Microsystems.
-	VACATION: Fix pattern matching for addresses to ignore.
-	VACATION: Don't reply to addresses of the form owner-*
-		or *-owner.

-8.11.1/8.11.1	2000/09/27
-	Fix SMTP EXPN command output if the address expands to a single
-		name.  Fix from John Beck of Sun Microsystems.
-	Don't try STARTTLS in the client if the PRNG has not been properly
-		seeded.  This problem only occurs on systems without
-		/dev/urandom.  Problem detected by Jan Krueger of
-		digitalanswers communications consulting gmbh and
-		Neil Rickert of Northern Illinois University.
-	Don't use the . and .. directories when expanding QueueDirectory
-		wildcards.
-	Do not try to cache LDAP connections across processes as a parent
-		process may close the connection before the child process
-		has completed.  Problem noted by Lai Yiu Fai of the Hong
-		Kong University of Science and Technology and Wolfgang
-		Hottgenroth of UUNET.
-	Use Timeout.fileopen to limit the amount of time spent trying to
-		read the LDAP secret from a file.
-	Prevent SIGTERM from removing a command line submitted item after
-		the user submits the message and before the first delivery
-		attempt completes.  Problem noted by Max France of AlphaNet.
-		Fix from Neil Rickert of Northern Illinois University.
-	Deal correctly with MaxMessageSize restriction if message size is
-		greater than 2^31.  Problem noted by Tim "Darth Dice" Bosserman
-		of EarthLink.
-	Turn off queue checkpointing if CheckpointInterval is set to zero.
-	Treat an empty home directory (from getpw*() or $HOME) as
-		non-existent instead of treating it as /.  Problem noted by
-		Todd C. Miller of Courtesan Consulting.
-	Don't drop duplicate headers when reading a queued item.  Problem
-		noted by Motonori Nakamura of Kyoto University.
-	Avoid bogus error text when logging the savemail panic "cannot
-		save rejected email anywhere".  Problem noted by Marc G.
-		Fournier of Acadia University.
-	If an LDAP search fails because the LDAP server went down, close
-		the map so subsequent searches reopen the map.  If there are
-		multiple LDAP servers, the down server will be skipped and
-		one of the others may be able to take over.
-	Set the ${load_avg} macro to the current load average, not the
-		previous load average query result.
-	If a non-optional map used in a check_* ruleset can't be opened,
-		return a temporary failure to the remote SMTP client
-		instead of ignoring the map.  Problem noted by Allan E
-		Johannesen of Worcester Polytechnic Institute.
-	Avoid a race condition when queuing up split envelopes by saving
-		the split envelopes before the original envelope.
-	Fix a bug in the PH_MAP code which caused mail to bounce instead of
-		defer if the PH server could not be contacted.  From Mark
-		Roth of the University of Illinois at Urbana-Champaign.
-	Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and
-		ETRN.  Problem noted by Erik R. Leo of SoVerNet.

-		RCPT commands from 501 to 555 per RFC 1869.  Problem
-		reported to Postfix by Robert Norris of Monash University.
-	Prevent overwriting the argument of -B on certain OS.  Problem
-		noted by Matteo Gelosa of I.NET S.p.A.
-	Use the proper routine for freeing memory with Netscape's LDAP
-		client libraries.  Patch from Paul Hilchey of the
-		University of British Columbia.
-	Portability:
-		Move the NETINET6 define to devtools/OS/SunOS.5.{8,9}
-			instead of defining it in conf.h so users can
-			override the setting.  Suggested by
-			Henrik Nordstrom of Ericsson.
-		On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of
-			/usr/lib/sendmail for rmail and vacation.  From
-			Jeff A. Earickson of Colby College.
-		On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which
-			does not exist).  From Jeff A. Earickson of Colby
-			College.
-		Avoid using the UCB subsystem on NCR MP-RAS 3.x.  From
-			Tom Moore of NCR.
-		NeXT 3.X and 4.X installs man pages in /usr/man.  From
-			Hisanori Gogota of NTT/InterCommunicationCenter.
-		Solaris 8 and later include /var/run.  The default PID file
-			location is now /var/run/sendmail.pid.  From John
-			Beck of Sun Microsystems.
-		SFIO includes snprintf() for those operating systems
-			which do not.  From Todd C. Miller of Courtesan
-			Consulting.

-		Problem noted by Kaspar Brand of futureLab AG.
-	CONFIG: Change 553 SMTP reply code to 501 to avoid problems with
-		errors in the MAIL address.
-	CONFIG: Fix FEATURE(nouucp) usage in example .mc files.  Problem
-		noted by Ron Jarrell of Virginia Tech.
-	CONFIG: Add support for Solaris 8 (and later) as OSTYPE(solaris8).
-		Contributed by John Beck of Sun Microsystems.
-	CONFIG: Set confFROM_HEADER such that the mail hub can possibly add
-		GECOS information for an address.  This more closely
-		matches pre-8.10 nullclient behavior.  From Per Hedeland of
-		Ericsson.
-	CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for
-		SMTP to all *smtp* mailers and those for RELAY to the relay
-		mailer as described in cf/README.
-	MAIL.LOCAL: Open the mailbox as the recipient not root so quotas
-		are obeyed.  Problem noted by Damian Kuczynski of NIK.
-	MAKEMAP: Do not change a map's owner to the TrustedUser if using
-		makemap to 'unmake' the map.
-	RMAIL: Avoid overflowing the list of recipients being passed to
-		sendmail.
-	RMAIL: Invoke sendmail with '-G' to indicate this is a gateway
-		submission.  Problem noted by Kari Hurtta of the Finnish

-	SECURITY: If sendmail is installed as a non-root set-user-ID binary
-		(not the normal case), some operating systems will still
-		keep a saved-uid of the effective-uid when sendmail tries
-		to drop all of its privileges.  If sendmail needs to drop
-		these privileges and the operating system doesn't set the
-		saved-uid as well, exit with an error.  Problem noted by
-		Kari Hurtta of the Finnish Meteorological Institute.
-	SECURITY: sendmail depends on snprintf() NUL terminating the string
-		it populates.  It is possible that some broken
-		implementations of snprintf() exist that do not do this.
-		Systems in this category should compile with
-		-DSNPRINTF_IS_BROKEN=1.  Use test/t_snprintf.c to test your
-		system and report broken implementations to
-		sendmail-bugs@sendmail.org and your OS vendor.  Problem
-		noted by Slawomir Piotrowski of TELSAT GP.
-	Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS).
-		Implementation influenced by the example programs of
-		OpenSSL and the work of Lutz Jaenicke of TU Cottbus.
-	Add new STARTTLS related options CACERTPath, CACERTFile,
-		ClientCertFile, ClientKeyFile, DHParameters, RandFile,
-		ServerCertFile, and ServerKeyFile.  These are documented in
-		cf/README and doc/op/op.*.
-	New STARTTLS related macros: ${cert_issuer}, ${cert_subject},
-		${tls_version}, ${cipher}, ${cipher_bits}, ${verify},
-		${server_name}, and ${server_addr}.  These are documented
-		in cf/README and doc/op/op.*.
-	Add support for the Entropy Gathering Daemon (EGD) for better
-		random data.
-	New DontBlameSendmail option InsufficientEntropy for systems which
-		don't properly seed the PRNG for OpenSSL but want to
-		try to use STARTTLS despite the security problems.
-	Support the security layer in SMTP AUTH for mechanisms which
-		support encryption.  Based on code contributed by Tim
-		Martin of CMU.
-	Add new macro ${auth_ssf} to reflect the SMTP AUTH security
-		strength factor.
-	LDAP's -1 (single match only) flag was not honored if the -z
-		(delimiter) flag was not given.  Problem noted by ST Wong of
-		the Chinese University of Hong Kong.  Fix from Mark Adamson
-		of CMU.
-	Add more protection from accidentally tripping OpenLDAP 1.X's
-		ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute().
-		Suggested by Kurt Zeilenga of OpenLDAP.
-	Fix the default family selection for DaemonPortOptions.  As
-		documented, unless a family is specified in a
-		DaemonPortOptions option, "inet" is the default.  It is
-		also the default if no DaemonPortOptions value is set.
-		Therefore, IPv6 users should configure additional sockets
-		by adding DaemonPortOptions settings with Family=inet6 if
-		they wish to also listen on IPv6 interfaces.  Problem noted
-		by Jun-ichiro itojun Hagino of the KAME Project.
-	Set ${if_family} when setting ${if_addr} and ${if_name} to reflect
-		the interface information for an outgoing connection.
-		Not doing so was creating a mismatch between the socket
-		family and address used in subsequent connections if the
-		M=b modifier was set in DaemonPortOptions.  Problem noted
-		by John Beck of Sun Microsystems.
-	If DaemonPortOptions modifier M=b is used, determine the socket
-		family based on the IP address.  ${if_family} is no longer
-		persistent (i.e., saved in qf files).  Patch from John Beck
-		of Sun Microsystems.
-	sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family}
-		macros for both the incoming interface address/family and
-		the outgoing interface address/family.  In order for M=b
-		modifier in DaemonPortOptions to work properly, preserve
-		the incoming information in the queue file for later
-		delivery attempts.
-	Use SMTP error code and enhanced status code from check_relay in
-		responses to commands.  Problem noted by Jeff Wasilko of
-		smoe.org.
-	Add more vigilance in checking for putc() errors on output streams
-		to protect from a bug in Solaris 2.6's putc().  Problem
-		noted by Graeme Hewson of Oracle.
-	The LDAP map -n option (return attribute names only) wasn't working.
-		Problem noted by Ajay Matia.
-	Under certain circumstances, an address could be listed as deferred
-		but would be bounced back to the sender as failed to be
-		delivered when it really should have been queued.  Problem
-		noted by Allan E Johannesen of Worcester Polytechnic Institute.
-	Prevent a segmentation fault in a child SMTP process from getting
-		the SMTP transaction out of sync.  Problem noted by Per
-		Hedeland of Ericsson.
-	Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT
-		is defined to avoid a core dump due to incompatibilities
-		between sfio and stdio.  Problem noted by Neil Rickert
-		of Northern Illinois University.
-	Don't log useless envelope ID on initial connection log.  Problem
-		noted by Kari Hurtta of the Finnish Meteorological Institute.
-	Convert the free disk space shown in a control socket status query
-		to kilobyte units.
-	If TryNullMXList is True and there is a temporary DNS failure
-		looking up the hostname, requeue the message for a later
-		attempt.  Problem noted by Ari Heikkinen of Pohjois-Savo
-		Polytechnic.
-	Under the proper circumstances, failed connections would be recorded
-		as "Bad file number" instead of "Connection failed" in the
-		queue file and persistent host status.  Problem noted by
-		Graeme Hewson of Oracle.
-	Avoid getting into an endless loop if a non-hoststat directory exists
-		within the hoststatus directory (e.g., lost+found).
-		Patch from Valdis Kletnieks of Virginia Tech.
-	Make sure Timeout.queuereturn=now returns a bounce message to the
-		sender.  Problem noted by Per Hedeland of Ericsson.
-	If a message data file can't be opened at delivery time, panic and
-		abort the attempt instead of delivering a message that
-		states "<<< No Message Collected >>>".
-	Fixup the GID checking code from 8.10.2 as it was overly
-		restrictive.  Problem noted by Mark G. Thomas of Mark
-		G. Thomas Consulting.
-	Preserve source port number instead of replacing it with the ident
-		port number (113).
-	Document the queue status characters in the mailq man page.
-		Suggested by Ulrich Windl of the Universitat Regensburg.
-	Process queued items in which none of the recipient addresses have
-		host portions (or there are no recipients).  Problem noted
-		by Valdis Kletnieks of Virginia Tech.
-	If a cached LDAP connection is used for multiple maps, make sure
-		only the first to open the connection is allowed to close
-		it so a later map close doesn't break the connection for
-		other maps.  Problem noted by Wolfgang Hottgenroth of UUNET.
-	Netscape's LDAP libraries do not support Kerberos V4
-		authentication.  Patch from Rainer Schoepf of the
-		University of Mainz.
-	Provide workaround for inconsistent handling of data passed
-		via callbacks to Cyrus SASL prior to version 1.5.23.
-	Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.  Omission
-		noted by Ulrich Windl of the Universitat Regensburg.
-	Portability:
-		Add the ability to read IPv6 interface addresses into class
-			'w' under FreeBSD (and possibly others).  From Jun
-			Kuriyama of IMG SRC, Inc. and the FreeBSD Project.
-		Replace code for finding the number of CPUs on HPUX.
-		NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not
-			work properly causing problems if the accept()
-			fails and the socket needs to be reopened.  Patch
-			from Tom Moore of NCR.
-		NetBSD uses a .0 extension of formatted man pages.  From
-			Andrew Brown of Crossbar Security.
-		Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED
-			for calls to getipnodebyname().  The Linux
-			implementation is broken so AI_ADDRCONFIG is stripped
-			under Linux.  From John Beck of Sun Microsystems and
-			John Kennedy of Cal State University, Chico.
-	CONFIG: Catch invalid addresses containing a ',' at the wrong place.
-		Patch from Neil Rickert of Northern Illinois University.
-	CONFIG: New variables for the new sendmail options:
-		confCACERT_PATH			CACERTPath
-		confCACERT			CACERTFile

-		tags to the access database to support these policies.  See
-		cf/README for more information.
-	CONFIG: Add TLS information to the Received: header.
-	CONFIG: Call tls_client ruleset from check_mail in case it wasn't
-		called due to a STARTTLS command.
-	CONFIG: If TLS_PERM_ERR is defined, TLS related errors are permanent
-		instead of temporary.
-	CONFIG: FEATURE(`relay_hosts_only') didn't work in combination with
-		the access map and relaying to a domain without using a To:
-		tag.  Problem noted by Mark G. Thomas of Mark G. Thomas
-		Consulting.
-	CONFIG: Set confEBINDIR to /usr/sbin to match the devtools entry in
-		OSTYPE(`linux') and OSTYPE(`mklinux').  From Tim Pierce of
-		RootsWeb.com.
-	CONFIG: Make sure FEATURE(`nullclient') doesn't use aliasing and
-		forwarding to make it as close to the old behavior as
-		possible.  Problem noted by George W. Baltz of the
-		University of Maryland.
-	CONFIG: Added OSTYPE(`darwin') for Mac OS X and Darwin users.  From
-		Wilfredo Sanchez of Apple Computer, Inc.
-	CONFIG: Changed the map names used by FEATURE(`ldap_routing') from
-		ldap_mailhost and ldap_mailroutingaddress to ldapmh and
-		ldapmra as underscores in map names cause problems if
-		underscore is in OperatorChars.  Problem noted by Bob Zeitz
-		of the University of Alberta.
-	CONFIG: Apply blacklist_recipients also to hosts in class {w}.
-		Patch from Michael Tratz of Esosoft Corporation.
-	CONFIG: Use A=TCP ... instead of A=IPC ... in SMTP mailers.
-	CONTRIB: Add link_hash.sh to create symbolic links to the hash
-		of X.509 certificates.
-	CONTRIB: passwd-to-alias.pl:  More protection from special characters;
-		treat special shells as root aliases; skip entries where the
-		GECOS full name and username match.  From Ulrich Windl of the
-		Universitat Regensburg.
-	CONTRIB: qtool.pl: Add missing last_modified_time method and fix a
-		typo.  Patch from Graeme Hewson of Oracle.
-	CONTRIB: re-mqueue.pl: Improve handling of a race between re-mqueue
-		and sendmail.  Patch from Graeme Hewson of Oracle.
-	CONTRIB: re-mqueue.pl: Don't exit(0) at end so can be called as
-		subroutine Patch from Graeme Hewson of Oracle.
-	CONTRIB: Add movemail.pl (move old mail messages between queues by
-		calling re-mqueue.pl) and movemail.conf (configuration
-		script for movemail.pl).  From Graeme Hewson of Oracle.
-	CONTRIB: Add cidrexpand (expands CIDR blocks as a preprocessor to
-		makemap).  From Derek J. Balling of Yahoo,Inc.
-	DEVTOOLS: INSTALL_RAWMAN installation option mistakenly applied any
-		extension modifications (e.g., MAN8EXT) to the installation
-		target.  Patch from James Ralston of Carnegie Mellon
-		University.
-	DEVTOOLS: Add support for SunOS 5.9.
-	DEVTOOLS: New option confLN contains the command used to create
-		links.
-	LIBSMDB: Berkeley DB 2.X and 3.X errors might be lost and not
-		reported.
-	MAIL.LOCAL: DG/UX portability.  Problem noted by Tim Boyer of
-		Denman Tire Corporation.
-	MAIL.LOCAL: Prevent a possible DoS attack when compiled with
-		-DCONTENTLENGTH.  Based on patch from 3APA3A@SECURITY.NNOV.RU.
-	MAILSTATS: Fix usage statement (-p and -o are optional).
-	MAKEMAP: Change man page layout as workaround for problem with nroff
-		and -man on Solaris 7.  Patch from Larry Williamson.
-	RMAIL: AIX 4.3 has snprintf().  Problem noted by David Hayes of
-		Black Diamond Equipment, Limited.
-	RMAIL: Prevent a segmentation fault if the incoming message does not
-		have a From line.
-	VACATION: Read all of the headers before deciding whether or not
-		to respond instead of stopping after finding recipient.
-	Added Files:

-
-8.10.2/8.10.2	2000/06/07
-	SECURITY: Work around broken Linux setuid() implementation.
-		On Linux, a normal user process has the ability to subvert
-		the setuid() call such that it is impossible for a root
-		process to drop its privileges.  Problem noted by Wojciech
-		Purczynski of elzabsoft.pl.
-	SECURITY: Add more vigilance around set*uid(), setgid(), setgroups(),
-		initgroups(), and chroot() calls.
-	Added Files:
-		test/t_setuid.c
-
-8.10.1/8.10.1	2000/04/06
-	SECURITY: Limit the choice of outgoing (client-side) SMTP
-		Authentication mechanisms to those specified in
-		AuthMechanisms to prevent information leakage.  We do not
-		recommend use of PLAIN for outgoing mail as it sends the
-		password in clear text to possibly untrusted servers.  See
-		cf/README's DefaultAuthInfo section for additional information.
-	Copy the ident argument for openlog() to avoid problems on some
-		OSs.  Based on patch from Rob Bajorek from Webhelp.com.
-	Avoid bogus error message when reporting an alias line as too long.
-	Avoid bogus socket error message if sendmail.cf version level is
-		greater than sendmail binary supported version.  Patch
-		from John Beck of Sun Microsystems.
-	Prevent a malformed ruleset (missing right hand side) from causing
-		a segmentation fault when using address test mode.  Based on
-		patch from John Beck of Sun Microsystems.
-	Prevent memory leak from use of NIS maps and yp_match(3).  Problem
-		noted by Gil Kloepfer of the University of Texas at Austin.
-	Fix queue file permission checks to allow for TrustedUser ownership.
-	Change logging of errors from the trust_auth ruleset to LogLevel 10
-		or higher.
-	Avoid simple password cracking attacks against SMTP AUTH by using
-		exponential delay after too many tries within one connection.
-	Encode an initial empty AUTH challenge as '=', not as empty string.
-	Avoid segmentation fault on EX_SOFTWARE internal error logs.
-		Problem noted by Allan E Johannesen of Worcester
-		Polytechnic Institute.
-	Ensure that a header check which resolves to $#discard actually
-		discards the message.
-	Emit missing value warnings for aliases with no right hand side
-		when newaliases is run instead of only when delivery is
-		attempted to the alias.
-	Remove AuthOptions missing value warning for consistency with other
-		flag options.
-	Portability:
-		SECURITY: Specify a run-time shared library search path for
-			AIX 4.X instead of using the dangerous AIX 4.X
-			linker semantics.  AIX 4.X users should consult
-			sendmail/README for further information.  Problem
-			noted by Valdis Kletnieks of Virginia Tech.
-		Avoid use of strerror(3) call.  Problem noted by Charles
-			Levert of Ecole Polytechnique de Montreal.
-		DGUX requires -lsocket -lnsl and has a non-standard install
-			program.  From Tim Boyer of Denman Tire Corporation.
-		HPUX 11.0 has a broken res_search() function.
-		Updates to devtools/OS/NeXT.3.X, NeXT.4.X, and NEXTSTEP.4.X
-			from J. P. McCann of E I A.
-		Digital UNIX/Compaq Tru64 5.0 now includes snprintf(3).
-			Problem noted by Michael Long of Info Avenue Internet
-			Services, LLC.
-		Modern (post-199912) OpenBSD versions include working
-			strlc{at,py}(3) functions.  From Todd C. Miller of
-			Courtesan Consulting.
-		SINIX doesn't have random(3).  From Gerald Rinske of
-			Siemens Business Services.
-	CONFIG: Change error message about unresolvable sender domain to
-		include the sender address.  Proposed by Wolfgang Rupprecht
-		of WSRCC.
-	CONFIG: Fix usenet mailer calls.
-	CONFIG: If RELAY_MAILER_FLAGS is not defined, use SMTP_MAILER_FLAGS
-		to be backward compatible with 8.9.
-	CONFIG: Change handling of default case @domain for virtusertable
-		to allow for +*@domain to deal with +detail.
-	CONTRIB: Remove converting.sun.configs -- it is obsolete.
-	DEVTOOLS: confUBINMODE was being ignored.  Fix from KITAZIMA, Tuneki
-		of NEC.
-	DEVTOOLS: Add to NCR platform list and include the architecture
-		(i486).  From Tom J. Moore of NCR.
-	DEVTOOLS: SECURITY: Change method of linking with sendmail utility
-		libraries to work around the AIX 4.X and SunOS 4.X linker's
-		overloaded -L option.  Problem noted by Valdis Kletnieks of
-		Virginia Tech.
-	DEVTOOLS: configure.sh was overriding the user's choice for
-		confNROFF.  Problem noted by Glenn A. Malling of Syracuse
-		University.
-	DEVTOOLS: New variables conf_prog_LIB_POST and confBLDVARIANT added
-		for other internal projects but included in the open source
-		release.
-	LIBSMDB: Check for ".db" instead of simply "db" at the end of the
-		map name to determine whether or not to add the extension.
-		This fixes makemap when building the userdb file.  Problem
-		noted by Andrew J Cole of the University of Leeds.
-	LIBSMDB: Allow a database to be opened for updating and created if
-		it doesn't already exist.  Problem noted by Rand Wacker of
-		Sendmail.
-	LIBSMDB: If type is SMDB_TYPE_DEFAULT and both NEWDB and NDBM are
-		available, fall back to NDBM if NEWDB open fails.  This
-		fixes praliases.  Patch	from John Beck of Sun Microsystems.
-	LIBSMUTIL: safefile()'s SFF_NOTEXCL check was being misinterpreted
-		as SFF_NOWRFILES.
-	OP.ME: Clarify some issues regarding mailer flags.  Suggested by
-		Martin Mokrejs of The Charles University and Neil Rickert of
-		Northern Illinois University.
-	PRALIASES: Restore 8.9.X functionality of being able to search for
-		particular keys in a database by specifying the keys on the

-	SECURITY: The safe file checks now back track through symbolic
-		links to make sure the files can't be compromised due
-		to poor permissions on the parent directories of the
-		symbolic link target.
-	SECURITY: Only root, TrustedUser, and users in class t can rebuild
-		the alias map.  Problem noted by Michal Zalewski of the
-		"Internet for Schools" project (IdS).
-	SECURITY: There is a potential for a denial of service attack if
-		the AutoRebuildAliases option is set as a user can kill the
-		sendmail process while it is rebuilding the aliases file
-		(leaving it in an inconsistent state).  This option and
-		its use is deprecated and will be removed from a future
-		version of sendmail.
-	SECURITY: Make sure all file descriptors (besides stdin, stdout, and
-		stderr) are closed before restarting sendmail.  Problem noted
-		by Michal Zalewski of the "Internet for Schools" project
-		(IdS).
-	Begin using /etc/mail/ for sendmail related files.  This affects
-		a large number of files.  See cf/README for more details.
-	The directory structure of the distribution has changed slightly
-		for easier code sharing among the programs.
-	Support SMTP AUTH (see RFC 2554).  New macros for this purpose
-		are ${auth_authen}, ${auth_type}, and ${auth_author}
-		which hold the client's authentication credentials,
-		the mechanism used for authentication, and the
-		authorization identity (i.e., the AUTH= parameter if
-		supplied).  Based on code contributed by Tim Martin of CMU.
-	On systems which use the Torek stdio library (all of the BSD
-		distributions), use memory-buffered files to reduce
-		file system overhead by not creating temporary files on
-		disk.  Contributed by Exactis.com, Inc.
-	New option DataFileBufferSize to control the maximum size of a
-		memory-buffered data (df) file before a disk-based file is
-		used.  Contributed by Exactis.com, Inc.
-	New option XscriptFileBufferSize to control the maximum size of a
-		memory-buffered transcript (xf) file before a disk-based
-		file is used.  Contributed by Exactis.com, Inc.
-	sendmail implements RFC 2476 (Message Submission), e.g., it can
-		now listen on several different ports.  Use:
-		O DaemonPortOptions=Name=MSA, Port=587, M=E
-		to run a Message Submission Agent (MSA); this is turned
-		on by default in m4-generated .cf files; it can be turned
-		off with FEATURE(`no_default_msa').
-	The 'XUSR' SMTP command is deprecated.  Mail user agents should
-		begin using RFC 2476 Message Submission for initial user
-		message submission.  XUSR may disappear from a future release.
-	The new '-G' (relay (gateway) submission) command line option
-		indicates that the message being submitted from the command
-		line is for relaying, not initial submission.  This means
-		the message will be rejected if the addresses are not fully
-		qualified and no canonicalization will be done.  Future
-		releases may even reject improperly formed messages.
-	The '-U' (initial user submission) command line option is
-		deprecated and may be removed from a future release.
-		Mail user agents should begin using '-G' to indicate that
-		this is a relay submission (the inverse of -U).
-	The next release of sendmail will assume that any message submitted
-		from the command line is an initial user submission and act
-		accordingly.
-	If sendmail doesn't have enough privileges to run a .forward
-		program or deliver to file as the owner of that file, the
-		address is marked as unsafe.  This means if RunAsUser is
-		set, users won't be able to use programs or delivery to
-		files in their .forward files.  Administrators can override
-		this by setting the DontBlameSendmail option to the new
-		setting NonRootSafeAddr.
-	Allow group or world writable directories if the sticky bit is set
-		on the directory and DontBlameSendmail is set to
-		TrustStickyBit.  Based on patch from Chris Metcalf of
-		InCert Software.
-	Prevent logging of unsafe directory paths for non-existent forward
-		files if the new DontWarnForwardFileInUnsafeDirPath bit is
-		set in the DontBlameSendmail option.  Requested by many.
-	New Timeout.control option to limit the total time spent satisfying
-		a control socket request.
-	New Timeout.resolver options for controlling BIND resolver
-		settings:
-		Timeout.resolver.retrans
-			Sets the resolver's retransmission time interval (in
-			seconds).  Sets both Timeout.resolver.retrans.first
-			and Timeout.resolver.retrans.normal.
-		Timeout.resolver.retrans.first
-			Sets the resolver's retransmission time interval (in
-			seconds) for the first attempt to deliver a message.
-		Timeout.resolver.retrans.normal
-			Sets the resolver's retransmission time interval (in
-			seconds) for all resolver lookups except the first
-			delivery attempt.
-		Timeout.resolver.retry
-			Sets the number of times to retransmit a resolver
-			query.  Sets both Timeout.resolver.retry.first
-			and Timeout.resolver.retry.normal.
-		Timeout.resolver.retry.first
-			Sets the number of times to retransmit a resolver
-			query for the first attempt to deliver a message.
-		Timeout.resolver.retry.normal
-			Sets the number of times to retransmit a resolver
-			query for all resolver lookups except the first
-			delivery attempt.

-	Support multiple queue directories.  To use multiple queues, supply
-		a QueueDirectory option value ending with an asterisk.  For
-		example, /var/spool/mqueue/q* will use all of the
-		directories or symbolic links to directories beginning with
-		'q' in /var/spool/mqueue as queue directories.  Keep in
-		mind, the queue directory structure should not be changed
-		while sendmail is running.  Queue runs create a separate
-		process for running each queue unless the verbose flag is
-		given on a non-daemon queue run.  New items are randomly
-		assigned to a queue.  Contributed by Exactis.com, Inc.
-	Support different directories for qf, df, and xf queue files; if
-		subdirectories or symbolic links to directories of those names
-		exist in the queue directories, they are used for the
-		corresponding queue files.  Keep in mind, the queue
-		directory structure should not be changed while sendmail is
-		running.  Proposed by Mathias Koerber of Singapore
-		Telecommunications Ltd.
-	New queue file naming system which uses a filename guaranteed to be
-		unique for 60 years.  This allows queue IDs to be assigned
-		without fancy file system locking.  Queued items can be
-		moved between queues easily.  Contributed by Exactis.com,
-		Inc.
-	Messages which are undeliverable due to temporary address failures
-		(e.g., DNS failure) will now go to the FallBackMX host, if
-		set.  Contributed by Exactis.com, Inc.
-	New command line option '-L tag' which sets the identifier used for
-		syslog.  Contributed by Exactis.com, Inc.
-	QueueSortOrder=Filename will sort the queue by filename.  This
-		avoids opening and reading each queue file when preparing
-		to run the queue.  Contributed by Exactis.com, Inc.
-	Shared memory counters and microtimers functionality has been
-		donated by Exactis.com, Inc.
-	The SCCS ID tags have been replaced with RCS ID tags.
-	Allow trusted users (those on a T line or in $=t) to set the
-		QueueDirectory (Q) option without an X-Authentication-Warning:
-		being added.  Suggested by Michael K. Sanders.
-	IPv6 support based on patches from John Kennedy of Cal State
-		University, Chico, Motonori Nakamura of Kyoto University,
-		and John Beck of Sun Microsystems.
-	In low-disk space situations, where sendmail would previously refuse
-		connections, still accept them, but only allow ETRN commands.
-		Suggested by Mathias Koerber of Singapore Telecommunications
-		Ltd.
-	The [IPC] builtin mailer now allows delivery to a UNIX domain socket
-		on systems which support them.  This can be used with LMTP
-		local delivery agents which listen on a named socket.  An
-		example mailer might be:
-			Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n,

-		Code contributed by Lyndon Nerenberg of Messaging Direct.
-	The [TCP] builtin mailer name is now deprecated.  Use [IPC]
-		instead.
-	The first mailer argument in the [IPC] mailer is now checked for a
-		legitimate value.  Possible values are TCP (for TCP/IP
-		connections), IPC (which will be deprecated in a future
-		version), and FILE (for UNIX domain socket delivery).
-	PrivacyOptions=goaway no longer includes the noetrn and the noreceipts
-		flags.
-	PrivacyOptions=nobodyreturn instructs sendmail not to include the
-		body of the original message on delivery status
-		notifications.
-	Don't announce DSN if PrivacyOptions=noreceipts is set.  Problem noted
-		by Dan Bernstein, fix from Robert Harker of Harker Systems.
-	Accept the SMTP RSET command even when rejecting commands due to TCP
-		Wrappers or the check_relay ruleset.  Problem noted by
-		Steve Schweinhart of America Online.
-	Warn if OperatorChars is set multiple times.  OperatorChars should
-		not be set after rulesets are defined.  Suggested by
-		Mitchell Blank Jr of Exec-PC.
-	Do not report temporary failure on delivery to files.  In
-		interactive delivery mode, this would result in two SMTP
-		responses after the DATA command.  Problem noted by
-		Nik Conwell of Boston University.
-	Check file close when mailing to files.  Problem noted by Nik
-		Conwell of Boston University.
-	Avoid a segmentation fault when using the LDAP map.  Patch from
-		Curtis W. Hillegas of Princeton University.
-	Always bind to the LDAP server regardless of whether you are using
-		ldap_open() or ldap_init().  Fix from Raj Kunjithapadam of
-		@Home Network.
-	New ruleset trust_auth to determine whether a given AUTH=
-		parameter of the MAIL command should be trusted.  See SMTP
-		AUTH, cf/README, and doc/op/op.ps.
-	Allow new named config file rules check_vrfy, check_expn, and
-		check_etrn for VRFY, EXPN, and ETRN commands, respectively,
-		similar to check_rcpt etc.
-	Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr},
-		${mail_mailer}, ${mail_host}, ${mail_addr} that hold
-		the results of parsing the RCPT and MAIL arguments, i.e.
-		the resolved triplet from $#mailer $@host $:addr.
-		From Kari Hurtta of the Finnish Meteorological Institute.
-	New macro ${client_resolve} which holds the result of the resolve
-		call for ${client_name}: OK, FAIL, FORGED, TEMP.  Proposed
-		by Kari Hurtta of the Finnish Meteorological Institute.
-	New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold
-		the corresponding DSN parameter values.  Proposed by
-		Mathias Herberts.
-	New macro ${msg_size} which holds the value of the SIZE= parameter,
-		i.e., usually the size of the message (in an ESMTP dialogue),
-		before the message has been collected, thereafter it holds
-		the message size as computed by sendmail (and can be used
-		in check_compat).
-	The macro ${deliveryMode} now specifies the current delivery mode
-		sendmail is using instead of the value of the DeliveryMode
-		option.
-	New macro ${ntries} holds the number of delivery attempts.
-	Drop explicit From: if same as what would be generated only if it is
-		a local address.  From Motonori Nakamura of Kyoto University.
-	Write pid to file also if sendmail only processes the queue.
-		Proposed by Roy J. Mongiovi of Georgia Tech.
-	Log "low on disk space" only when necessary.
-	New macro ${load_avg} can be used to check the current load average.
-		Suggested by Scott Gifford of The Internet Ramp.
-	Return-Receipt-To: header implies DSN request if option RrtImpliesDsn
-		is set.
-	Flag -S for maps to specify the character which is substituted
-		for spaces (instead of the default given by O BlankSub).
-	Flag -D for maps: perform no lookup in deferred delivery mode.
-		This flag is set by default for the host map.  Based on a
-		proposal from Ian MacPhedran of the University of Saskatchewan.
-	Open maps only on demand, not at startup.
-	Log warning about unsupported IP address families.
-	New option MaxHeadersLength allows to specify a maximum length
-		of the sum of all headers.  This can be used to prevent
-		a denial-of-service attack.
-	New option MaxMimeHeaderLength which limits the size of MIME
-		headers and parameters within those headers.  This option
-		is intended to protect mail user agents from buffer
-		overflow attacks.
-	Added option MaxAliasRecursion to specify the maximum depth of
-		alias recursion.
-	New flag F=6 for mailers to strip headers to seven bit.
-	Map type syslog to log the key via syslogd.
-	Entries in the alias file can be continued by putting a backslash
-		directly before the newline.
-	New option DeadLetterDrop to define the location of the system-wide
-		dead.letter file, formerly hardcoded to
-		/usr/tmp/dead.letter.  If this option is not set (the
-		default), sendmail will not attempt to save to a
-		system-wide dead.letter file if it can not bounce the mail
-		to the user nor postmaster.  Instead, it will rename the qf
-		file as it has in the past when the dead.letter file
-		could not be opened.
-	New option PidFile to define the location of the pid file.  The
-		value of this option is macro expanded.
-	New option ProcessTitlePrefix specifies a prefix string for the
-		process title shown in 'ps' listings.
-	New macros for use with the PidFile and ProcessTitlePrefix options
-		(along with the already existing macros):
-		${daemon_info}      Daemon information, e.g.
-		                    SMTP+queueing@00:30:00
-		${daemon_addr}	    Daemon address, e.g., 0.0.0.0
-		${daemon_family}    Daemon family, e.g., inet, inet6, etc.
-		${daemon_name}      Daemon name, e.g., MSA.
-		${daemon_port}	    Daemon port, e.g., 25
-		${queue_interval}   Queue run interval, e.g., 00:30:00
-	New macros especially for virtual hosting:
-		${if_name}	hostname of interface of incoming connection.
-		${if_addr}	address of interface of incoming connection.
-		The latter is only set if the interface does not belong to the
-		loopback net.
-	If a message being accepted via a method other than SMTP and
-		would be rejected by a header check, do not send the message.
-		Suggested by Phil Homewood of Mincom Pty Ltd.
-	Don't strip comments for header checks if $>+ is used instead of $>.
-		Provide header value as quoted string in the macro
-		${currHeader} (possibly truncated to MAXNAME).  Suggested by
-		Jan Krueger of Unix-AG of University of Hannover.
-		The length of the header value is stored in ${hdrlen}.
-	H*: allows to specify a default ruleset for header checks.  This
-		ruleset will only be called if the individual header does
-		not have its own ruleset assigned.  Suggested by Jan
-		Krueger of Unix-AG of University of Hannover.
-		The name of the header field stored in ${hdr_name}.
-	Comments (i.e., text within parentheses) in rulesets are not
-		removed if the config file version is greater than or equal
-		to 9.  For example, "R$+ ( 1 )		$@ 1" matches the
-		input "token (1)" but does not match "token".
-	Avoid removing the Content-Transfer-Encoding MIME header on
-		MIME messages.  Problem noted by Sigurbjorn B. Larusson of
-		Multimedia Consumer Services.  Fix from Per Hedeland of
-		Ericsson.
-	Avoid duplicate Content-Transfer-Encoding MIME header on
-		messages with 8-bit text in headers.  Problem noted by
-		Per Steinar Iversen of Oslo College.  Fix from Per Hedeland
-		of Ericsson.
-	Avoid keeping maps locked longer than necessary when re-opening a
-		modified database map file.  Problem noted by Chris Adams
-		of Renaissance Internet Services.
-	Resolving to the $#error mailer with a temporary failure code (e.g.,
-		$#error $@ tempfail $: "400 Temporary failure") will now
-		queue up the message instead of bouncing it.
-	Be more liberal in acceptable responses to an SMTP RSET command as
-		standard does not provide any indication of what to do when
-		something other than 250 is received.  Based on a patch
-		from Steve Schweinhart of America Online.
-	New option TrustedUser allows to specify a user who can own
-		important files instead of root.  This requires HASFCHOWN.
-	Fix USERDB conditional so compiling with NEWDB or HESIOD and
-		setting USERDB=0 works.  Fix from Jorg Zanger of Schock.
-	Fix another instance (similar to one in 8.9.3) of a network failure
-		being mis-logged as "Illegal Seek" instead of whatever
-		really went wrong.  From John Beck of Sun Microsystems.
-	$? tests also whether the macro is non-null.
-	Print an error message if a mailer definition contains an invalid
-		equate name.
-	New mailer equate /= to specify a directory to chroot() into before
-		executing the mailer program.  Suggested by Igor Vinokurov.
-	New mailer equate W= to specify the maximum time to wait for the
-		mailer to return after sending all data to it.
-	Only free memory from the process list when adding a new process
-		into a previously filled slot.  Previously, the memory was
-		freed at removal time.  Since removal can happen in a
-		signal handler, this may leave the memory map in an
-		inconsistent state.  Problem noted by Jeff A. Earickson and
-		David Cooley of Colby College.
-	When using the UserDB @hostname catch-all, do not try to lookup
-		local users in the passwd file.  The UserDB code has
-		already decided the message will be passed to another host
-		for processing.  Fix from Tony Landells of Burdett
-		Buckeridge Young Limited.
-	Support LDAP authorization via either a file containing the
-		password or Kerberos V4 using the new map options
-		'-ddistinguished_name', '-Mmethod', and '-Pfilename'.  The
-		distinguished_name is who to login as.  The method can be
-		one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or
-		LDAP_AUTH_KRBV4.  The filename is the file containing the
-		secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos
-		ticket file for LDAP_AUTH_KRBV4.  Patch from Booker Bense
-		of Stanford University.
-	The ldapx map has been renamed to ldap.  The use of ldapx is
-		deprecated and will be removed in a future version.
-	If the result of an LDAP search returns a multi-valued attribute
-		and the map has the column delimiter set, it turns that
-		response into a delimiter separated string.  The LDAP map
-		will traverse multiple entries as well.  LDAP alias maps
-		automatically set the column delimiter to the comma.
-		Based on patch from Booker Bense of Stanford University and
-		idea from Philip A. Prindeville of Mirapoint, Inc.
-	Support return of multiple values for a single LDAP lookup.  The
-		values to be returned should be in a comma separated string.
-		For example, `-v "email,emailother"'.  Patch from
-		Curtis W. Hillegas of Princeton University.
-	Allow the use of LDAP for alias maps.
-	If no LDAP attributes are specified in an LDAP map declaration, all
-		attributes found in the match will be returned.
-	Prevent commas in quoted strings in the AliasFile value from
-		breaking up a single entry into multiple entries.  This is
-		needed for LDAP alias file specifications to allow for
-		comma separated key and value strings.
-	Keep connections to LDAP server open instead of opening and closing
-		for each lookup.  To reduce overhead, sendmail will cache
-		connections such that multiple maps which use the same
-		host, port, bind DN, and authentication will only result in
-		a single connection to that host.
-	Put timeout in the proper place for USE_LDAP_INIT.
-	Be more careful about checking for errors and freeing memory on
-		LDAP lookups.
-	Use asynchronous LDAP searches to save memory and network
-		resources.
-	Do not copy LDAP query results if the map's match only flag is set.
-	Increase portability to the Netscape LDAP libraries.
-	Change the parsing of the LDAP filter specification.  '%s' is still
-		replaced with the literal contents of the map lookup key --
-		note that this means a lookup can be done using the LDAP
-		special characters.  The new '%0' token can be used instead
-		of '%s' to encode the key buffer according to RFC 2254.
-		For example, if the LDAP map specification contains '-k
-		"(user=%s)"' and a lookup is done on "*", this would be
-		equivalent to '-k "(user=*)"' -- matching ANY record with a
-		user attribute.  Instead, if the LDAP map specification
-		contains '-k "(user=%0)"' and a lookup is done on "*", this
-		would be equivalent to '-k "(user=\2A)"' -- matching a user
-		with the name "*".
-	New LDAP map flags: "-1" requires a single match to be returned, if
-		more than one is returned, it is equivalent to no records
-		being found; "-r never|always|search|find" sets the LDAP
-		alias dereference option; "-Z size" limits the number of
-		matches to return.
-	New option LDAPDefaultSpec allows a default map specification for
-		LDAP maps.  The value should only contain LDAP specific
-		settings such as "-h host -p port -d bindDN", etc.  The
-		settings will be used for all LDAP maps unless they are
-		specified in the individual map specification ('K'
-		command).  This option should be set before any LDAP maps
-		are defined.
-	Prevent an NDBM alias file opening loop when the NDBM open
-		continually fails.  Fix from Roy J. Mongiovi of Georgia
-		Tech.
-	Reduce memory utilization for smaller symbol table entries.  In
-		particular, class entries get much smaller, which can be
-		important if you have large classes.
-	On network-related temporary failures, record the hostname which
-		gave error in the queued status message.  Requested by
-		Ulrich Windl of the Universitat Regensburg.
-	Add new F=% mailer flag to allow for a store and forward
-		configuration.  Mailers which have this flag will not attempt
-		delivery on initial receipt of a message or on queue runs
-		unless the queued message is selected using one of the
-		-qI/-qR/-qS queue run modifiers or an ETRN request.  Code
-		provided by Philip Guenther of Gustavus Adolphus College.
-	New option ControlSocketName which, when set, creates a daemon
-		control socket.  This socket allows an external program to
-		control and query status from the running sendmail daemon
-		via a named socket, similar to the ctlinnd interface to the
-		INN news server.  Access to this interface is controlled by
-		the UNIX file permissions on the named socket on most UNIX
-		systems (see sendmail/README for more information).  An
-		example control program is provided as contrib/smcontrol.pl.
-	Change the default values of QueueLA from 8 to (8 * numproc) and
-		RefuseLA from 12 to (12 * numproc) where numproc is the
-		number of processors online on the system (if that can be
-		determined).  For single processor machines, this change
-		has no effect.
-	Don't return body of message to postmaster on "Too many hops" bounces.
-		Based on fix from Motonori Nakamura of Kyoto University.
-	Give more detailed DSN descriptions for some cases.  Patch from
-		Motonori Nakamura of Kyoto University.
-	Logging of alias, forward file, and UserDB expansion now happens
-		at LogLevel 11 or higher instead of 10 or higher.
-	Logging of an envelope's complete delivery (the "done" message) now
-		happens at LogLevel 10 or higher instead of 11 or higher.
-	Logging of TCP/IP or UNIX standard input connections now happens at
-		LogLevel 10 or higher.  Previously, only TCP/IP connections
-		were logged, and on at LogLevel 12 or higher.  Setting
-		LogLevel to 10 will now assist users in tracking frequent
-		connection-based denial of service attacks.
-	Log basic information about authenticated connections at LogLevel
-		10 or higher.
-	Log SMTP Authentication mechanism and author when logging the sender
-		information (from= syslog line).
-	Log the DSN code for each recipient if one is available as a new
-		equate (dsn=).
-	Macro expand PostmasterCopy and DoubleBounceAddress options.
-	New "ph" map for performing ph queries in rulesets, see
-		sendmail/README for details.  Contributed by Mark Roth
-		of the University of Illinois at Urbana-Champaign.
-	Detect temporary lookup failures in the host map if looking up a
-		bracketed IP address.  Problem noted by Kari Hurtta of the
-		Finnish Meteorological Institute.
-	Do not report a Remote-MTA on local deliveries.  Problem noted by
-		Kari Hurtta of the Finnish Meteorological Institute.
-	When a forward file points to an alias which runs a program, run
-		the program as the default user and the default group, not
-		the forward file user.  This change also assures the
-		:include: directives in aliases are also processed using
-		the default user and group.  Problem noted by Sergiu
-		Popovici of DNT Romania.
-	Prevent attempts to save a dead.letter file for a user with
-		no home directory (/no/such/directory).  Problem noted by
-		Michael Brown of Finnigan FT/MS.
-	Include message delay and number of tries when logging that a
-		message has been completely delivered (LogLevel of 10 or
-		above).  Suggested by Nick Hilliard of Ireland Online.
-	Log the sender of a message even if none of the recipients were
-		accepted.  If some of the recipients were rejected, it is
-		helpful to know the sender of the message.
-	Check the root directory (/) when checking a path for safety.
-		Problem noted by John Beck of Sun Microsystems.
-	Prevent multiple responses to the DATA command if DeliveryMode is
-		interactive and delivering to an alias which resolves to
-		multiple files.
-	Macros in the helpfile are expanded if the helpfile version is 2 or
-		greater (see below); the help function doesn't print the
-		version of sendmail any longer, instead it is placed in
-		the helpfile ($v).  Suggested by Chuck Foster of UUNET
-		PIPEX.  Additionally, comment lines (starting with #) are
-		skipped and a version line (#vers) is introduced.  The
-		helpfile version for 8.10.0 is 2, if no version or an older
-		version is found, a warning is logged.  The '#vers'
-		directive should be placed at the top of the help file.
-	Use fsync() when delivering to a file to guarantee the delivery to
-		disk succeeded.  Suggested by Nick Christenson.
-	If delivery to a file is unsuccessful, truncate the file back to its
-		length before the attempt.
-	If a forward points to a filename for delivery, change to the
-		user's uid before checking permissions on the file.  This
-		allows delivery to files on NFS mounted directories where
-		root is remapped to nobody.  Problem noted by Harald
-		Daeubler of Universitaet Ulm.
-	purgestat and sendmail -bH purge only expired (Timeout.hoststatus)
-		host status files, not all files.
-	Any macros stored in the class $={persistentMacros} will be saved
-		in the queue file for the message and set when delivery
-		is attempted on the queued item.  Suggested by Kyle Jones of
-		Wonderworks Inc.
-	Add support for storing information between rulesets using the new
-		macro map class.  This can be used to store information
-		between queue runs as well using $={persistentMacros}.
-		Based on an idea from Jan Krueger of Unix-AG of University
-		of Hannover.
-	New map class arith to allow for computations in rules.  The
-		operation (+, -, *, /, l (for less than), and =) is given
-		as key.  The two operands are specified as arguments; the
-		lookup returns the result of the computation.  For example,
-		"$(arith l $@ 4 $@ 2 $)" will return "FALSE" and
-		"$(arith + $@ 4 $@ 2 $)" will return "6".
-	Add new syntax for header declarations which decide whether to
-		include the header based on a macro rather than a mailer
-		flag:
-			H?${MyMacro}?X-My-Header: ${MyMacro}
-		This should be used along with $={persistentMacros}.
-		It can be used for adding headers to a message based on
-		the results of check_* and header check rulesets.
-	Allow new named config file rule check_eoh which is called after
-		all of the headers have been collected.  The input to the
-		ruleset the number of headers and the size of all of the
-		headers in bytes separated by $|.  This ruleset along with
-		the macro storage map can be used to correlate information
-		gathered between headers and to check for missing headers.
-		See cf/README or doc/op/op.ps for an example.
-	Change the default for the MeToo option to True to correspond
-		to the clarification in the DRUMS SMTP Update spec.  This
-		option is deprecated and will be removed from a future
-		version.
-	Change the sendmail binary default for SendMimeErrors to True.
-	Change the sendmail binary default for SuperSafe to True.
-	Display ruleset names in debug and address test mode output
-		if referencing a named ruleset.
-	New mailer equate m= which will limit the number of messages
-		delivered per connection on an SMTP or LMTP mailer.
-	Improve QueueSortOrder=Host by reversing the hostname before
-		using it to sort.  Now all the same domains are really run
-		through the queue together.  If they have the same MX host,
-		then they will have a much better opportunity to use the
-		connection cache if available.  This should be a reasonable
-		performance improvement.  Patch from Randall Winchester of
-		the University of Maryland.
-	If a message is rejected by a header check ruleset, log who would
-		have received the message if it had not been rejected.
-	New "now" value for Timeout.queuereturn to bounce entries from the
-		queue immediately.  No delivery attempt is made.
-	Increase sleeping time exponentially after too many "bad" commands
-		up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}-
-		COMMANDS).
-	New option ClientPortOptions similar to DaemonPortOptions
-		but for outgoing connections.
-	New suboptions for DaemonPortOptions: Name (a name used for
-		error messages and logging) and Modifiers, i.e.
-			a	require authentication
-			b	bind to interface through which mail has
-				been received
-			c	perform hostname canonification
-			f	require fully qualified hostname
-			h	use name of interface for outgoing HELO
-				command
-			C	don't perform hostname canonification
-			E	disallow ETRN (see RFC 2476)
-	New suboption for ClientPortOptions: Modifiers, i.e.
-			h	use name of interface for HELO command
-	The version number for queue files (qf) has been incremented to 4.
-	Log unacceptable HELO/EHLO domain name attempts if LogLevel is set
-		to 10 or higher.  Suggested by Rick Troxel of the National
-		Institutes of Health.
-	If a mailer dies, print the status in decimal instead of octal
-		format.  Suggested by Michael Shapiro of Sun Microsystems.
-	Limit the length of all MX records considered for delivery to 8k.
-	Move message priority from sender to recipient logging.  Suggested by
-		Ulrich Windl of the Universitat Regensburg.
-	Add support for Berkeley DB 3.X.
-	Add fix for Berkeley DB 2.X fcntl() locking race condition.
-		Requires a post-2.7.5 version of Berkeley DB.
-	Support writing traffic log (sendmail -X option) to a FIFO.
-		Patch submitted by Rick Heaton of Network Associates, Inc.
-	Do not ignore Timeout settings in the .cf file when a Timeout
-		sub-options is set on the command line.  Problem noted by
-		Graeme Hewson of Oracle.
-	Randomize equal preference MX records each time delivery is
-		attempted via a new connection to a host instead of once per
-		session.  Suggested by Scott Salvidio of Compaq.
-	Implement enhanced status codes as defined by RFC 2034.
-	Add [hostname] to class w for the names of all interfaces unless
-		DontProbeInterfaces is set. This is useful for sending mails
-		to hosts which have dynamically assigned names.
-	If a message is bounced due to bad MIME conformance, avoid bouncing
-		the bounce for the same reason.  If the body is not 8-bit
-		clean, and EightBitMode isn't set to pass8, the body will
-		not be included in the bounce.  Problem noted by Valdis
-		Kletnieks of Virginia Tech.
-	The timeout for sending a message via SMTP has been changed from
-		'${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which
-		simply checks for progress on sending data every 5 minutes.
-		This will detect the inability to send information quicker
-		and reduce the number of processes simply waiting to
-		timeout.
-	Prevent a segmentation fault on systems which give a partial filled
-		interface address structure when loading the system network
-		interface addresses.  Fix from Reinier Bezuidenhout of
-		Nanoteq.
-	Add a compile-time configuration macro, MAXINTERFACES, which
-		indicates the number of interfaces to read when probing
-		for hostnames and IP addresses for class w ($=w).  The
-		default value is 512.  Based on idea from Reinier
-		Bezuidenhout of Nanoteq.
-	If the RefuseLA option is set to 0, do not reject connections based
-		on load average.
-	Allow ruleset 0 to have a name.  Problem noted by Neil Rickert of
-		Northern Illinois University.
-	Expand the Return-Path: header at delivery time, after "owner-"
-		envelope splitting has occurred.
-	Don't try to sort the queue if there are no entries. Patch from
-		Luke Mewburn from RMIT University.
-	Add a "/quit" command to address test mode.
-	Include the proper sender in the UNIX "From " line and Return-Path:
-		header when undeliverable mail is saved to ~/dead.letter.
-		Problem noted by Kari Hurtta of the Finnish Meteorological
-		Institute.
-	The contents of a class can now be copied to another class using
-		the syntax: "C{Dest} $={Source}".  This would copy all of
-		the items in class $={Source} into the class $={Dest}.
-	Include original envelope's error transcript in bounces created for
-		split (owner-) envelopes to see the original errors when
-		the recipients were added.  Based on fix from Motonori
-		Nakamura of Kyoto University.
-	Show reason for permanent delivery errors directly after the
-		addresses.  From Motonori Nakamura of Kyoto University.
-	Prevent a segmentation fault when bouncing a split-envelope
-		message.  Patch from Motonori Nakamura of Kyoto University.
-	If the specification for the queue run interval (-q###) has a
-		syntax error, consider the error fatal and exit.
-	Pay attention to CheckpointInterval during LMTP delivery.  Problem
-		noted by Motonori Nakamura of Kyoto University.
-	On operating systems which have setlogin(2), use it to set the
-		login name to the RunAsUserName when starting as a daemon.
-		This is for delivery to programs which use getlogin().
-		Based on fix from Motonori Nakamura of Kyoto University.
-	Differentiate between "command not implemented" and "command
-		unrecognized" in the SMTP dialogue.
-	Strip returns from forward and include files.  Problem noted by
-		Allan E Johannesen of Worcester Polytechnic Institute.
-	Prevent a core dump when using 'sendmail -bv' on an address which
-		resolves to the $#error mailer with a temporary failure.
-		Based on fix from Neil Rickert of Northern Illinois
-		University.
-	Prevent multiple deliveries of a message with a "non-local alias"
-		pointing to a local user, if canonicalization fails
-		the message was requeued *and* delivered to the alias.
-	If an invalid ruleset is declared, the ruleset name could be
-		ignored and its rules added to S0.  Instead, ignore the
-		ruleset lines as well.
-	Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient
-		success DSN fields as well as duplicate entries for a
-		single address due to S5 and UserDB processing.  Problems
-		noted by Kari Hurtta of the Finnish Meteorological
-		Institute.
-	Turn off timeouts when exiting sendmail due to an interrupt signal
-		to prevent the timeout from firing during the exit process.
-		Problem noted by Michael Shapiro of Sun Microsystems.
-	Do not append @MyHostName to non-RFC822 addresses output by the EXPN
-		command or on Final-Recipient: and X-Actual-Recipient: DSN
-		headers.  Non-RFC822 addresses include deliveries to
-		programs, file, DECnet, etc.
-	Fix logic for determining if a local user is using -f or -bs to
-		spoof their return address.  Based on idea from Neil Rickert
-		of Northern Illinois University and patch from Per Hedeland
-		of Ericsson.
-	Report the proper UID in the bounce message if an :include: file is
-		owned by a uid that doesn't map to a username and the
-		:include: file contains delivery to a file or program.
-		Problem noted by John Beck of Sun Microsystems.
-	Avoid the attempt of trying to send a second SMTP QUIT command if
-		the remote server responds to the first QUIT with a 4xx
-		response code and drops the connection.  This behavior was
-		noted by Ulrich Windl of the Universitat Regensburg when
-		sendmail was talking to the Mercury 1.43 MTA.
-	If a hostname lookup times out and ServiceSwitchFile is set but the
-		file is not present, the lookup failure would be marked as
-		a permanent failure instead of a temporary failure.  Fix
-		from Russell King of the ARM Linux Project.
-	Handle aliases or forwards which deliver to programs using tabs
-		instead of spaces between arguments.  Problem noted by Randy
-		Wormser.  Fix from Neil Rickert of Northern Illinois
-		University.
-	Allow MaxRecipientsPerMessage option to be set on the command line
-		by normal users (e.g., sendmail won't drop its root
-		privileges) to allow overrides for message submission via
-		'sendmail -bs'.
-	Set the names for help file and statistics file to "helpfile" and
-		"statistics", respectively, if no parameters are given for
-		them in the .cf file.
-	Avoid bogus 'errbody: I/O Error -7' log messages when sending
-		success DSN messages for messages relayed to non-DSN aware
-		systems.  Problem noted by Juergen Georgi of RUS University
-		of Stuttgart and Kyle Tucker of Parexel International.
-	Prevent +detail information from interfering with local delivery to
-		multiple users in the same transaction (F=m).
-	Add H_FORCE flag for the X-Authentication-Warning: header, so it
-		will be added even if one already exists.  Problem noted
-		by Michal Zalewski of Marchew Industries.
-	Stop processing SMTP commands if the SMTP connection is dropped.
-		This prevents a remote system from flooding the connection
-		with commands and then disconnecting.  Previously, the
-		server would process all of the buffered commands.  Problem
-		noted by Michal Zalewski of Marchew Industries.
-	Properly process user-supplied headers beginning with '?'.  Problem
-		noted by Michal Zalewski of Marchew Industries.
-	If multiple header checks resolve to the $#error mailer, use the
-		last permanent (5XX) failure if any exist.  Otherwise, use
-		the last temporary (4XX) failure.
-	RFC 1891 requires "hexchar" in a "xtext" to be upper case.  Patch
-		from Ronald F. Guilmette of Infinite Monkeys & Co.
-	Timeout.ident now defaults to 5 seconds instead of 30 seconds to
-		prevent the now common delays associated with mailing to a
-		site which drops IDENT packets.  Suggested by many.
-	Persistent host status data is not reloaded disk when current data
-		is available in the in-memory cache.  Problem noted by Per
-		Hedeland of Ericsson.
-	mailq displays unprintable characters in addresses as their octal
-		representation and a leading backslash.  This avoids problems
-		with "unprintable" characters.  Problem noted by Michal
-		Zalewski of the "Internet for Schools" project (IdS).
-	The mail line length limit (L= equate) was adding the '!' indicator
-		one character past the limit.  This would cause subsequent
-		hops to break the line again.  The '!' is now placed in
-		the last column of the limit if the line needs to be broken.
-		Problem noted by Joe Pruett of Q7 Enterprises.  Based on fix
-		from Per Hedeland of Ericsson.
-	If a resolver ANY query is larger than the UDP packet size, the
-		resolver will fall back to TCP.  However, some
-		misconfigured firewalls black 53/TCP so the ANY lookup
-		fails whereas an MX or A record might succeed.  Therefore,
-		don't fail on ANY queries.
-	If an SMTP recipient is rejected due to syntax errors in the
-		address, do not send an empty postmaster notification DSN
-		to the postmaster.  Problem noted by Neil Rickert of
-		Northern Illinois University.
-	Allow '_' and '.' in map names when parsing a sequence map
-		specification.  Patch from William Setzer of North Carolina
-		State University.
-	Fix hostname in logging of read timeouts for the QUIT command on
-		cached connections.  Problem noted by Neil Rickert of
-		Northern Illinois University.
-	Use a more descriptive entry to log "null" connections, i.e.,
-		"host did not issue MAIL/EXPN/VRFY/ETRN during connection".
-	Fix a file descriptor leak in ONEX mode.
-	Portability:
-		Reverse signal handling logic such that sigaction(2) with
-			the SA_RESTART flag is the preferred method and the
-			other signal methods are only tried if SA_RESTART
-			is not available.  Problem noted by Allan E
-			Johannesen of Worcester Polytechnic Institute.
-		AIX 4.x supports the sa_len member of struct sockaddr.
-			This allows network interface probing to work
-			properly.  Fix from David Bronder of the
-			University of Iowa.
-		AIX 4.3 has snprintf() support.
-		Use "PPC" as the architecture name when building under
-			AIX.  This will be reflected in the obj.* directory
-			name.

-		Improved HPUX 11.0 portability.
-		Properly determine the number of CPUs on FreeBSD 2.X,
-			FreeBSD 3.X, HP/UX 10.X and HP/UX 11.X.
-		Remove special IRIX ABI cases from Build script and the OS
-			files.  Use the standard 'cc' options used by SGI
-			in building the operating system.  Users can
-			override the defaults by setting confCC and
-			confLIBSEARCHPATH appropriately.
-		IRIX nsd map support from Bob Mende of SGI.
-		Minor devtools fixes for IRIX from Bob Mende of SGI.
-		Linux patch for IP_SRCROUTE support from Joerg Dorchain
-			of MW EDV & ELECTRONIC.
-		Linux now uses /usr/sbin for confEBINDIR in the build
-			system.  From MATSUURA Takanori of Osaka University.
-		Remove special treatment for Linux PPC in the build
-			system.  From MATSUURA Takanori of Osaka University.
-		Motorolla UNIX SYSTEM V/88 Release 4.0 support from
-			Sergey Rusanov of the Republic of Udmurtia.
-		NCR MP-RAS 3.x includes regular expression support.  From
-			Tom J. Moore of NCR.
-		NEC EWS-UX/V series settings for _PATH_VENDOR_CF and
-			_PATH_SENDMAILPID from Oota Toshiya of
-			NEC Computers Group Planning Division.
-		Minor NetBSD owner/group tweaks from Ayamura Kikuchi, M.D.
-		NEWS-OS 6.X listed SYSLOG_BUFSIZE as 256 in confENVDEF and
-			1024 in conf.h.  Since confENVDEF would be used,
-			use that value in conf.h.
-		Use NeXT's NETINFO to get domain name.  From Gerd Knops of
-			BITart Consulting.
-		Use NeXT's NETINFO for alias and hostname resolution if
-			AUTO_NETINFO_ALIASES and AUTO_NETINFO_HOSTS are
-			defined.  Patch from Wilfredo Sanchez of Apple
-			Computer, Inc.
-		NeXT portability tweaks.  Problems reported by Dragan
-			Milicic of the University of Utah and J. P. McCann
-			of E I A.
-		New compile flag FAST_PID_RECYCLE: set this if your system
-			can reuse the same PID in the same second.
-		New compile flag HASFCHOWN: set this if your OS has
-			fchown(2).
-		New compile flag HASRANDOM: set this to 0 if your OS does
-			not have random(3).  rand() will be used instead.
-		New compile flag HASSRANDOMDEV: set this if your OS has
-			srandomdev(3).
-		New compile flag HASSETLOGIN: set this if your OS has
-			setlogin(2).
-		Replace SINIX and ReliantUNIX support with version
-			specific SINIX files.  From Gerald Rinske of
-			Siemens Business Services.
-		Use the 60-second load average instead of the 5 second load
-			average on Compaq Tru64 UNIX (formerly Digital
-			UNIX).  From Chris Teakle of the University of Qld.
-		Use ANSI C by default for Compaq Tru64 UNIX.  Suggested by
-			Randall Winchester of Swales Aerospace.
-		Correct setgroups() prototype for Compaq Tru64 UNIX.
-			Problem noted by Randall Winchester of Swales
-			Aerospace.
-		Hitachi 3050R/3050RX and 3500 Workstations running
-			HI-UX/WE2 4.02, 6.10 and 7.10 from Motonori
-			NAKAMURA of Kyoto University.
-		New compile flag NO_GETSERVBYNAME: set this to disable
-			use of getservbyname() on systems which can
-			not lookup a service by name over NIS, such as
-			HI-UX.  Patch from Motonori NAKAMURA of Kyoto
-			University.
-		Use devtools/bin/install.sh on SCO 5.x.  Problem noted
-			by Sun Wenbing of the China Engineering and
-			Technology Information Network.
-		make depend didn't work properly on UNIXWARE 4.2.  Problem

-		Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
-		Set confSTDIO_TYPE to torek for BSD-OS, FreeBSD, NetBSD,
-			and OpenBSD.
-		A recent Compaq Ultrix 4.5 Y2K patch has broken detection
-			of local_hostname_length().  See sendmail/README
-			for more details.  Problem noted by Allan E
-			Johannesen of Worcester Polytechnic Institute.
-	CONFIG: Begin using /etc/mail/ for sendmail related files.  This
-		affects a large number of files.  See cf/README for more
-		details.
-	CONFIG: New macro MAIL_SETTINGS_DIR contains the path (including
-		trailing slash) for the mail settings directory.
-	CONFIG: Increment version number of config file to 9.
-	CONFIG: OSTYPE(`bsdi1.0') and OSTYPE(`bsdi2.0') have been
-		deprecated and may be removed from a future release.
-		BSD/OS users should begin using OSTYPE(`bsdi').
-	CONFIG: OpenBSD 2.4 installs mail.local non-set-user-ID root.  This
-		requires a new OSTYPE(`openbsd').  From Todd C. Miller of
-		Courtesan Consulting.
-	CONFIG: New OSTYPE(`hpux11') for HP/UX 11.X.
-	CONFIG: A syntax error in check_mail would cause fake top-level
-		domains (.BITNET, .DECNET, .FAX, .USENET, and .UUCP) to
-		be improperly rejected as unresolvable.
-	CONFIG: New FEATURE(`dnsbl') takes up to two arguments (name of
-		DNS server, rejection message) and can be included
-		multiple times.
-	CONFIG: New FEATURE(`relay_mail_from') allows relaying if the
-		mail sender is listed as RELAY in the access map (and tagged
-		with From:).
-	CONFIG: Optional tagging of LHS in the access map (Connect:,
-		From:, To:) to enable finer control.
-	CONFIG: New FEATURE(`ldap_routing') implements LDAP address
-		routing.  See cf/README for a complete description of the
-		new functionality.
-	CONFIG: New variables for the new sendmail options:
-		confAUTH_MECHANISMS		AuthMechanisms
-		confAUTH_OPTIONS		AuthOptions
-		confCLIENT_OPTIONS		ClientPortOptions
-		confCONTROL_SOCKET_NAME		ControlSocketName
-		confDEAD_LETTER_DROP		DeadLetterDrop

-		confXF_BUFFER_SIZE		XscriptFileBufferSize
-	CONFIG: confDAEMON_OPTIONS has been replaced by DAEMON_OPTIONS(),
-		which takes the options as argument and can be used
-		multiple times; see cf/README for details.
-	CONFIG: Add a fifth mailer definition to MAILER(`smtp') called
-		"dsmtp".  This mail provides on-demand delivery using the
-		F=% mailer flag described above.  The "dsmtp" mailer
-		definition uses the new DSMTP_MAILER_ARGS which defaults
-		to "IPC $h".
-	CONFIG: New variables LOCAL_MAILER_MAXMSGS, SMTP_MAILER_MAXMSGS,
-		and RELAY_MAILER_MAXMSGS for setting the m= equate for the
-		local, smtp, and relay mailers respectively.
-	CONFIG: New variable LOCAL_MAILER_DSN_DIAGNOSTIC_CODE for setting
-		the DSN Diagnostic-Code type for the local mailer.  The
-		value should be changed with care.
-	CONFIG: FEATURE(`local_lmtp') now sets the DSN Diagnostic-Code type
-		for the local mailer to the proper value of "SMTP".
-	CONFIG: All included maps are no longer optional by default; if
-		there there is a problem with a map, sendmail will
-		complain.
-	CONFIG: Removed root from class E; use EXPOSED_USER(`root')
-		to get the old behavior.  Suggested by Joe Pruett
-		of Q7 Enterprises.
-	CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which
-		will not be masqueraded.  Proposed by Arne Wichmann
-		of MPI Saarbruecken, Griff Miller of PGS Tensor,
-		Jayme Cox of Broderbund Software Inc.
-	CONFIG: A list of exceptions for FEATURE(`nocanonify') can be
-		specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE,
-		i.e., a list of domains which are passed to $[ ... $]
-		for canonification. Based on an idea from Neil Rickert
-		of Northern Illinois University.
-	CONFIG: If `canonify_hosts' is specified as parameter for
-		FEATURE(`nocanonify') then addresses which have only
-		a hostname, e.g., <user@host>, will be canonified.
-	CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is
-		nevertheless added to addresses with more than one component
-		in it.
-	CONFIG: Canonification is no longer attempted for any host or domain
-		in class 'P' ($=P).
-	CONFIG: New class for matching virtusertable entries $={VirtHost} that
-		can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE.
-		FEATURE(`virtuser_entire_domain') can be used to apply this
-		class also to entire subdomains.  Hosts in this class are
-		treated as canonical in SCanonify2, i.e., a trailing dot
-		is added.
-	CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used,
-		include $={VirtHost} in $=R (hosts allowed to relay).
-	CONFIG: FEATURE(`generics_entire_domain') can be used to apply the
-		genericstable also to subdomains of $=G.
-	CONFIG: Pass "+detail" as %2 for virtusertable lookups.
-		Patch from Noam Freedman from University of Chicago.
-	CONFIG: Pass "+detail" as %1 for genericstable lookups.  Suggested
-		by Raymond S Brand of rsbx.net.
-	CONFIG: Allow @domain in genericstable to override masquerading.
-		Suggested by Owen Duffy from Owen Duffy & Associates.
-	CONFIG: LOCAL_DOMAIN() adds entries to class w.  Suggested by Steve
-		Hubert of University of Washington.
-	CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as
-		GNU is now the canonical system name.  From Mark
-		Kettenis of the University of Amsterdam.
-	CONFIG: OSTYPE(`unixware7') updates from Larry Rosenman.
-	CONFIG: Do not include '=' in option expansion if there is no value
-		associated with the option.  From Andrew Brown of
-		Graffiti World Wide, Inc.
-	CONFIG: Add MAILER(`qpage') to define a new pager mailer.  Contributed
-		by Philip A. Prindeville of Enteka Enterprise Technology
-		Services.
-	CONFIG: MAILER(`cyrus') was not preserving case for mail folder
-		names.  Problem noted by Randall Winchester of Swales
-		Aerospace.
-	CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags
-		for the relay mailer.  Suggested by Doug Hughes of Auburn
-		University and Brian Candler.
-	CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path:
-		header) by default.  Suggested by Per Hedeland of Ericsson.
-	CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host].
-		Suggested by Kari Hurtta of the Finnish Meteorological
-		Institute.
-	CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS;
-		i.e., to set, add, or delete flags.
-	CONFIG: If SMTP AUTH is used then relaying is allowed for any user
-		who authenticated via a "trusted" mechanism, i.e., one that
-		is defined via TRUST_AUTH_MECH(`list of mechanisms').
-	CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay
-		after check_rcpt and allows for exceptions from the checks.
-	CONFIG: Map declarations have been moved into their associated
-		feature files to allow greater flexibility in use of
-		sequence maps.  Suggested by Per Hedeland of Ericsson.
-	CONFIG: New macro LOCAL_MAILER_EOL to override the default end of
-		line string for the local mailer.  Requested by Il Oh of
-		Willamette Industries, Inc.
-	CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is
-		converted to <user@d>
-	CONFIG: Reject bogus return address of <@@hostname>, generated by
-		Sun's older, broken configuration files.
-	CONFIG: FEATURE(`nullclient') now provides the full rulesets of a
-		normal configuration, allowing anti-spam checks to be
-		performed.
-	CONFIG: Don't return a permanent error (Relaying denied) if
-		${client_name} can't be resolved just temporarily.
-		Suggested by Kari Hurtta of the Finnish Meteorological
-		Institute.
-	CONFIG: Change numbered rulesets into named (which still can
-		be accessed by their numbers).
-	CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial
-		which describes whether to disallow "!" in the local part
-		of an address.
-	CONFIG: Call Local_localaddr from localaddr (S5) which can be used
-		to rewrite an address from a mailer which has the F=5 flag
-		set.  If the ruleset returns a mailer, the appropriate
-		action is taken, otherwise the returned tokens are ignored.
-	CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4
-		and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4.
-		The latter is kept around for backward compatibility.
-	CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries,
-		where "D.S.N" is an RFC 1893 compliant error code.
-	CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
-	CONFIG: Remove second space between username and date in UNIX From_
-		line.  Noted by Allan E Johannesen of Worcester Polytechnic
-		Institute.
-	CONFIG: Make sure all of the mailers have complete T= equates.
-	CONFIG: Extend FEATURE(`local_procmail') so it can now take
-		arguments overriding the mailer program, arguments, and
-		mailer definition flags.  This makes it possible to use
-		other programs such as maildrop for local delivery.
-	CONFIG: Emit warning if FEATURE(`local_lmtp') or
-		FEATURE(`local_procmail') is given after MAILER(`local').
-		Patch from Richard A. Nelson of IBM.
-	CONFIG: Add SMTP Authentication information to Received: header
-		default value (confRECEIVED_HEADER).
-	CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a
-		local mailer.  Problem noted by Per Hedeland of Ericsson.
-	CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the
-		University of California at Berkeley.
-	CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of
-		Illinois at Urbana-Champaign.
-	CONTRIB: etrn.pl now recognizes bogus host names.  Patch from
-		Bruce Barnett of GE's R&D Lab.
-	CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle
-		Corporation UK.
-	CONTRIB: Added qtool.pl to assist in managing the queues.
-	DEVTOOLS: Prevent user environment variables from interfering with
-		the Build scripts.  Problem noted by Ezequiel H. Panepucci of
-		Yale University.
-	DEVTOOLS: 'Build -M' will display the obj.* directory which will
-		be used for building.
-	DEVTOOLS: 'Build -A' will display the architecture that would be
-		used for a fresh build.
-	DEVTOOLS: New variable confRANLIB, set automatically by configure.sh.
-	DEVTOOLS: New variable confRANLIBOPTS for the options to send to
-		ranlib.
-	DEVTOOLS: 'Build -O <path>' will have the object files build in
-		<path>/obj.*.  Suggested by Bryan Costales of Exactis.
-	DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the
-		building of the man pages when defined.  Suggested by Bryan
-		Costales.
-	DEVTOOLS: New variables confNO_HELPFILE_INSTALL and
-		confNO_STATISTICS_INSTALL which will prevent the
-		installation of the sendmail helpfile and statistics file
-		respectively.  Suggested by Bryan Costales.
-	DEVTOOLS: Recognize ReliantUNIX as SINIX.  Patch from Gerald Rinske
-		of Siemens Business Services.
-	DEVTOOLS: New variable confSTDIO_TYPE which defines the type of
-		stdio library.  The new buffered file I/O depends on the
-		Torek stdio library.  This option can be either portable or
-		torek.
-	DEVTOOLS: New variables confSRCADD and confSMSRCADD which
-		correspond to confOBJADD and confSMOBJADD respectively.
-		They should contain the C source files for the object files
-		listed in confOBJADD and confSMOBJADD.  These file names
-		will be passed to the 'make depend' stage of compilation.
-	DEVTOOLS: New program specific variables for each of the programs
-		in the sendmail distribution.  Each has the form
-		`conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'.
-		The new variables are conf_prog_ENVDEF, conf_prog_LIBS,
-		conf_prog_SRCADD, and conf_prog_OBJADD.
-	DEVTOOLS: Build system redesign.  This should have little affect on
-		building the distribution, but documentation on the changes
-		are in devtools/README.
-	DEVTOOLS: Don't allow 'Build -f file' if an object directory already
-		exists.  Suggested by Valdis Kletnieks of Virginia Tech.
-	DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies
-		the path to the sendmail source directory.  confSRCDIR is a
-		new variable which identifies the root of the source
-		directories for all of the programs in the distribution.
-	DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build
-		time.  They can both still be overridden by setting the m4
-		macro.
-	DEVTOOLS: confSBINGRP now defaults to bin instead of kmem.
-	DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for
-		build configurations, and places objects in obj.prefix.*/.
-		Complains as 'Build -f file' does for existing object
-		directories.  Suggested by Tom Smith of Digital Equipment
-		Corporation.
-	DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted
-		manual pages in the directory tree specified by
-		confMANROOTMAN.
-	DEVTOOLS: If formatting the manual pages fails, copy in the
-		preformatted pages from the distribution.  The new variable
-		confCOPY specifies the copying program.
-	DEVTOOLS: Defining confFORCE_RMAIL will install rmail without
-		question.  Suggested by Terry Lambert of Whistle
-		Communications.
-	DEVTOOLS: confSTFILE and confHFFILE can be used to change the names
-		of the installed statistics and help files, respectively.
-	DEVTOOLS: Remove spaces in `uname -r` output when determining
-		operating system identity.  Problem noted by Erik
-		Wachtenheim of Dartmouth College.
-	DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that
-		will be search for the libraries specified in confLIBSEARCH.
-		Defaults to "/lib /usr/lib /usr/shlib".
-	DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying
-		how to strip binaries.  These are used by the new
-		install-strip target.
-	DEVTOOLS: New config file site.post.m4 which is included after
-		the others (if it exists).
-	DEVTOOLS: Change order of LIBS: first product specific libraries
-		then the default ones.
-	MAIL.LOCAL: Will not be installed set-user-ID root.  To use mail.local
-		as local delivery agent without LMTP mode, use
-		MODIFY_MAILER_FLAGS(`LOCAL', `+S')
-		to set the S flag.
-	MAIL.LOCAL: Do not reject addresses which would otherwise be
-		accepted by sendmail.  Suggested by Neil Rickert of
-		Northern Illinois University.
-	MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise
-		8BITMIME in the LHLO response.  Suggested by Kari Hurtta of
-		the Finnish Meteorological Institute.
-	MAIL.LOCAL: Add support for the maillock() routines by defining
-		MAILLOCK when compiling.  Also requires linking with
-		-lmail.  Patch from Neil Rickert of Northern Illinois
-		University.
-	MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is
-		defined when compiling.  Automatically set for Solaris 2.3
-		and later.  Patch from Neil Rickert of Northern Illinois
-		University.
-	MAIL.LOCAL: Move the initialization of the 'notifybiff' address
-		structure to the beginning of the program.  This ensures that
-		the getservbyname() is done before any seteuid to a possibly
-		unauthenticated user.  If you are using NIS+ and secure RPC
-		on a Solaris system, this avoids syslog messages such as,
-		"authdes_refresh: keyserv(1m) is unable to encrypt session
-		key."  Patch from Neil Rickert of Northern Illinois
-		University.
-	MAIL.LOCAL: Support group writable mail spool files when MAILGID is
-		set to the gid to use (-DMAILGID=6) when compiling.
-		Patch from Neil Rickert of Northern Illinois University.
-	MAIL.LOCAL: When a mail message included lines longer than 2046
-		characters (in LMTP mode), mail.local split the incoming
-		line up into 2046-character output lines (excluding the
-		newline).  If an input line was 2047 characters long
-		(excluding CR-LF) and the last character was a '.',
-		mail.local saw it as the end of input, transfered it to the
-		user mailbox and tried to write an `ok' back to sendmail.
-		If the message was much longer, both sendmail and
-		mail.local would deadlock waiting for each other to read
-		what they have written.  Problem noted by Peter Jeremy of
-		Alcatel Australia Limited.
-	MAIL.LOCAL: New option -b to return a permanent error instead of a
-		temporary error if a mailbox exceeds quota.  Suggested by
-		Neil Rickert of Northern Illinois University.
-	MAIL.LOCAL: The creation of a lockfile is subject to a global
-		timeout to avoid starvation.
-	MAIL.LOCAL: Properly parse addresses with multiple quoted
-		local-parts.  Problem noted by Ronald F. Guilmette of
-		Infinite Monkeys & Co.
-	MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR.
-	MAILSTATS: New -p option to invoke program mode in which stats are
-		printed in a machine readable fashion and the stats file
-		is reset.  Patch from Kevin Hildebrand of the University
-		of Maryland.
-	MAKEMAP: If running as root, automatically change the ownership of
-		generated maps to the TrustedUser as specified in the
-		sendmail configuration file.
-	MAKEMAP: New -C option to accept an alternate sendmail
-		configuration file to use for finding the TrustedUser
-		option.
-	MAKEMAP: New -u option to dump (unmap) a database.  Based on
-		code contributed by Roy Mongiovi of Georgia Tech.
-	MAKEMAP: New -e option to allow empty values.  Suggested by Philip
-		A. Prindeville of Enteka Enterprise Technology Services.
-	MAKEMAP: Compile cleanly on 64-bit operating systems.  Problem
-		noted by Gerald Rinske of Siemens Business Services.
-	OP.ME: Correctly document interaction between F=S and U= mailer
-		equates.  Problem noted by Bob Halley of Internet Engines.
-	OP.ME: Fixup Timeout documentation.  From Graeme Hewson of Oracle
-		Corporation UK.
-	OP.ME: The Timeout [r] option was incorrectly listed as "safe"
-		(e.g., sendmail would not drop root privileges if the
-		option was specified on the command line).  Problem noted
-		by Todd C. Miller of Courtesan Consulting.
-	PRALIASES: Handle the hash and btree map specifications for
-		Berkeley DB.  Patch from Brian J. Coan of the
-		Institute for Global Communications.
-	PRALIASES: Read the sendmail.cf file for the location(s) of the
-		alias file(s) if the -f option is not used.  Patch from
-		John Beck of Sun Microsystems.
-	PRALIASES: New -C option to specify an alternate sendmail
-		configuration file to use for finding alias file(s).  Patch
-		from John Beck of Sun Microsystems.
-	SMRSH: allow shell commands echo, exec, and exit.  Allow command
-		lists using || and &&.  Based on patch from Brian J. Coan
-		of the Institute for Global Communications.
-	SMRSH: Update README for the new Build system.  From Tim Pierce
-		of RootsWeb Genealogical Data Cooperative.
-	VACATION: Added vacation auto-responder to sendmail distribution.
-	LIBSMDB: Added abstracted database library.  Works with Berkeley
-		DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM.
-	Changed Files:
-		The Build script in the various program subdirectories are
-			no longer symbolic links.  They are now scripts
-			which execute the actual Build script in
-			devtools/bin.
-		All the manual pages are now written against -man and not
-			-mandoc as they were previously.
-		Add a simple Makefile to every directory so make instead
-			of Build will work (unless parameters are
-			required for Build).

-8.9.3/8.9.3	1999/02/04
-	SECURITY: Limit message headers to a maximum of 32K bytes (total
-		of all headers in a single message) to prevent a denial of
-		service attack.  This limit will be configurable in 8.10.
-		Problem noted by Michal Zalewski of the "Internet for
-		Schools" project (IdS).
-	Prevent segmentation fault on an LDAP lookup if the LDAP map
-		was closed due to an earlier failure.  Problem noted by
-		Jeff Wasilko of smoe.org.  Fix from Booker Bense of
-		Stanford University and Per Hedeland of Ericsson.
-	Preserve the order of the MIME headers in multipart messages
-		when performing the MIME header length check.  This
-		will allow PGP signatures to function properly.  Problem
-		noted by Lars Hecking of University College, Cork, Ireland.
-	If ruleset 5 rewrote the local address to an :include: directive,
-		the delivery would fail with an "aliasing/forwarding loop
-		broken" error.  Problem noted by Eric C Hagberg of Morgan
-		Stanley.  Fix from Per Hedeland of Ericsson.
-	Allow -T to work for bestmx maps.  Fix from Aaron Schrab of
-		ExecPC Internet Systems.
-	During the transfer of a message in an SMTP transaction, if a
-		TCP timeout occurs, the message would be properly queued
-		for later retry but the failure would be logged as
-		"Illegal Seek" instead of a timeout.  Problem noted by
-		Piotr Kucharski of the Warsaw School of Economics (SGH)
-		and Carles Xavier Munyoz Baldo of CTV Internet.
-	Prevent multiple deliveries on a self-referencing alias if the
-		F=w mailer flag is not set.  Problem noted by Murray S.
-		Kucherawy of Concentric Network Corporation and Per
-		Hedeland of Ericsson.
-	Do not strip empty headers but if there is no value and a
-		default is defined in sendmail.cf, use the default.
-		Problem noted by Philip Guenther of Gustavus Adolphus
-		College and Christopher McCrory of Netus, Inc.
-	Don't inherit information about the sender (notably the full name)
-		in SMTP (-bs) mode, since this might be called from inetd.
-	Accept any 3xx reply code in response to DATA command instead of
-		requiring 354.  This change will match the wording to be
-		published in the updated SMTP specification from the DRUMS
-		group of the IETF.
-	Portability:
-		AIX 4.2.0 or 4.2.1 may become updated by the fileset
-			bos.rte.net level 4.2.0.2.  This introduces the
-			softlink /usr/lib/libbind.a which should
-			not be used.  It conflicts with the resolver
-			built into libc.a.  "bind" has been removed
-			from the confLIBSEARCH BuildTools variable.
-			Users who have installed BIND 8.X will have
-			to add it back in their site.config.m4 file.
-			Problem noted by Ole Holm Nielsen of the
-			Technical University of Denmark.
-		CRAY TS 10.0.x from Sven Nielsen of San Diego
-			Supercomputer Center.
-		Improved LDAP version 3 integration based on input
-			from Kurt D. Zeilenga of the OpenLDAP Foundation,
-			John Beck of Sun Microsystems, and Booker Bense
-			of Stanford University.
-		Linux doesn't have a standard way to get the timezone
-			between different releases.  Back out the
-			change in 8.9.2 and don't attempt to derive
-			a timezone.  Problem reported by Igor S. Livshits
-			of the University of Illinois at Urbana-Champaign
-			and Michael Dickens of Tetranet Communications.
-		Reliant UNIX, the new name for SINIX, from Gert-Jan Looy
-			of Siemens/SNI.
-		SunOS 5.8 from John Beck of Sun Microsystems.
-	CONFIG: SCO UnixWare 2.1 and 7.0 need TZ to get the proper
-		timezone.  Problem noted by Petr Lampa of Technical
-		University of Brno.
-	CONFIG: Handle <@bestmx-host:user@otherhost> addressing properly
-		when using FEATURE(bestmx_is_local).  Patch from Neil W.
-		Rickert of Northern Illinois University.
-	CONFIG: Properly handle source routed and %-hack addresses on
-		hosts which the mailertable remaps to local:.  Patch from
-		Neil W. Rickert of Northern Illinois University.
-	CONFIG: Internal fixup of mailertable local: map value.  Patch from
-		Larry Parmelee of Cornell University.
-	CONFIG: Only add back +detail from host portion of mailer triplet
-		on local mailer triplets if it was originally +detail.
-		Patch from Neil W. Rickert of Northern Illinois University.
-	CONFIG: The bestmx_is_local checking done in check_rcpt would
-		cause later checks to fail.  Patch from Paul J Murphy of
-		MIDS Europe.
-	New Files:
-		BuildTools/OS/CRAYTS.10.0.x

-		BuildTools/OS/SunOS.5.8
-
-8.9.2/8.9.2	1998/12/30
-	SECURITY: Remove five second sleep on accepting daemon connections
-		due to an accept() failure.  This sleep could be used
-		for a denial of service attack.
-	Do not silently ignore queue files with names which are too long.
-		Patch from Bryan Costales of InfoBeat, Inc.
-	Do not store failures closing an SMTP session in persistent
-		host status.  Reported by Graeme Hewson of Oracle
-		Corporation UK.
-	Allow symbolic link forward files if they are in safe directories.
-		Problem noted by Andreas Schott of the Max Planck Society.
-	Missing columns in a text map could cause a segmentation fault.
-		Fix from David Lee of the University of Durham.
-	Note that for 8.9.X, PrivacyOptions=goaway also includes the
-		noetrn flag.  This is scheduled to change in a future
-		version of sendmail.  Problem noted by Theo Van Dinter of
-		Chrysalis Symbolic Designa and Alan Brown of Manawatu
-		Internet Services.
-	When trying to do host canonification in a Wildcard MX
-		environment, try an MX lookup of the hostname without the
-		default domain appended.  Problem noted by Olaf Seibert of
-		Polderland Language & Speech Technology.
-	Reject SMTP RCPT To: commands with only comments (i.e.
-		'RCPT TO: (comment)'.  Problem noted by Earle Ake of
-		Hassler Communication Systems Technology, Inc.
-	Handle any number of %s in the LDAP filter spec.  Patch from
-		Per Hedeland of Ericsson.
-	Clear ldapx open timeouts even if the map open failed to prevent
-		a segmentation fault.  Patch from Wayne Knowles of the
-		National Institute of Water & Atmospheric Research Ltd.
-	Do not syslog envelope clone messages when using address
-		verification (-bv).  Problem noted by Kari Hurtta of the
-		Finnish Meteorological Institute.
-	Continue to perform queue runs while in daemon mode even if the
-		daemon is rejecting connections due to a disk full
-		condition.  Problem noted by JR Oldroyd of TerraNet
-		Internet Services.
-	Include full filename on installation of the sendmail.hf file
-		in case the $HFDIR directory does not exist.  Problem
-		noted by Josef Svitak of Montana State University.
-	Close all maps when exiting the process with one exception.
-		Berkeley DB can use internal shared memory locking for
-		its memory pool.  Closing a map opened by another process
-		will interfere with the shared memory and locks of the
-		parent process leaving things in a bad state.  For
-		Berkeley DB, only close the map if the current process
-		is also the one that opened the map, otherwise only close
-		the map file descriptor.  Thanks to Yoseff Francus of
-		Collective Technologies for volunteering his system for
-		extended testing.
-	Avoid null pointer dereference on XDEBUG output for SMTP reply
-		failures.  Problem noted by Carlos Canau of EUnet Portugal.
-	On mailq and hoststat listings being piped to another program, such
-		as more, if the pipe closes (i.e., the user quits more),
-		stop sending output and exit.  Patch from Allan E Johannesen
-		of Worcester Polytechnic Institute.
-	In accordance with the documentation, LDAP map lookup failures
-		are now considered temporary failures instead of permanent
-		failures unless the -t flag is used in the map definition.
-		Problem noted by Booker Bense of Stanford University and
-		Eric C. Hagberg of Morgan Stanley.
-	Fix by one error reporting on long alias names.  Problem noted by
-		H. Paul Hammann of the Missouri Research and Education
-		Network.
-	Fix DontBlameSendmail=IncludeFileInUnsafeDirPath behavior.  Problem
-		noted by Barry S. Finkel of Argonne National Laboratory.
-	When automatically converting from 8 bit to quoted printable MIME,
-		be careful not to miss a multi-part boundary if that
-		boundary is preceded by a boundary-like line.  Problem
-		noted by Andreas Raschle of Ansid Inc.  Fix from
-		Kari Hurtta of the Finnish Meteorological Institute.
-	Avoid bogus reporting of "LMTP tobuf overflow" when the buffer
-		has enough space for the additional address.  Problem
-		noted by Steve Cliffe of the University of Wollongong.
-	Fix DontBlameSendmail=FileDeliveryToSymlink behavior.  Problem
-		noted by Alex Vorobiev of Swarthmore College.
-	If the check_compat ruleset resolves to the $#discard mailer,
-		discard the current recipient.  Unlike check_relay,
-		check_mail, and check_rcpt, the entire envelope is not
-		discarded.  Problem noted by RZ D. Rahlfs.  Fix from
-		Claus Assmann of Christian-Albrechts-University of Kiel.
-	Avoid segmentation fault when reading ServiceSwitchFile files with
-		bogus formatting.  Patch from Kari Hurtta of the Finnish
-		Meteorological Institute.
-	Support Berkeley DB 2.6.4 API change.
-	OP.ME: Pages weren't properly output on duplexed printers.  Fix
-		from Matthew Black of CSU Long Beach.
-	Portability:
-		Apple Rhapsody from Wilfredo Sanchez of Apple Computer, Inc.
-		Avoid a clash with IRIX 6.2 getopt.h and the UserDatabase
-			option structure.  Problem noted by Ashley M.
-			Kirchner of Photo Craft Laboratories, Inc.
-		Break out IP address to hostname translation for
-			reading network interface addresses into
-			class 'w'.  Patch from John Kennedy of
-			Cal State University, Chico.
-		AIX 4.x use -qstrict with -O3 to prevent the optimized
-			from changing the semantics of the compiled
-			program.  From Simon Travaglia of the
-			University of Waikato, New Zealand.

-	CONFIG: Catch @hostname,user@anotherhost.domain as relaying.
-		Problem noted by Mark Rogov of AirMedia, Inc.  Fix from
-		Claus Assmann of Christian-Albrechts-University of Kiel.
-	CONFIG: Do not refer to http://maps.vix.com/ on RBL rejections as
-		there are multiple RBL's available and the MAPS RBL may
-		not be the one in use.  Suggested by Alan Brown of
-		Manawatu Internet Services.
-	CONFIG: Properly strip route addresses (i.e., @host1:user@host2)
-		when stripping down a recipient address to check for
-		relaying.  Patch from Claus Assmann of
-		Christian-Albrechts-University of Kiel and Neil W Rickert
-		of Northern Illinois University.
-	CONFIG: Allow the access database to override RBL lookups.  Patch
-		from Claus Assmann of Christian-Albrechts-University of
-		Kiel.
-	CONFIG: UnixWare 7 support from Phillip P. Porch of The Porch
-		Dot Com.
-	CONFIG: Fixed check for deferred delivery mode warning.  Patch
-		from Claus Assmann of Christian-Albrechts-University of
-		Kiel and Per Hedeland of Ericsson.
-	CONFIG: If a recipient using % addressing is used, e.g.
-		user%site@othersite, and othersite's MX records are now
-		checked for local hosts if FEATURE(relay_based_on_MX) is
-		used.  Problem noted by Alexander Litvin of Lucky Net Ltd.
-		Patch from Alexander Litvin of Lucky Net Ltd and
-		Claus Assmann of Christian-Albrechts-University of Kiel.
-	MAIL.LOCAL: Prevent warning messages from appearing in the LMTP
-		stream.  Do not allow more than one response per recipient.
-	MAIL.LOCAL: Handle routed addresses properly when using LMTP.  Fix

-8.9.1/8.9.1	1998/07/02
-	If both an OS specific site configuration file and a generic
-		site.config.m4 file existed, only the latter was used
-		instead of both.  Problem noted by Geir Johannessen of
-		the Norwegian University of Science and Technology.
-	Fix segmentation fault while converting 8 bit to 7 bit MIME
-		multipart messages by trying to write to an unopened
-		file descriptor.  Fix from Kari Hurtta of the Finnish
-		Meteorological Institute.
-	Do not assume Message: and Text: headers indicate the end of
-		the header area when parsing MIME headers.  Problem noted
-		by Kari Hurtta of the Finnish Meteorological Institute.
-	Setting the confMAN#SRC Build variable would only effect the
-		installation commands.  The man pages would still be
-		built with .0 extensions.  Problem noted by Bryan
-		Costales of InfoBeat, Inc.
-	Installation of manual pages didn't honor the DESTDIR environment
-		variable.  Problem noted by Bryan Costales of InfoBeat, Inc.
-	If the check_relay ruleset resolved to the discard mailer, messages
-		were still delivered.  Problem noted by Mirek Luc of NASK.
-	Mail delivery to files would fail with an Operating System Error
-		if sendmail was not running as root, i.e., RunAsUser was set.
-		Problem noted by Leonard N. Zubkoff of Dandelion Digital.
-	Prevent MinQueueAge from interfering from queued items created
-		in the future, i.e., if the system clock was set ahead
-		and then back.  Problem noted by Michael Miller of the
-		University of Natal, Pietermaritzburg.
-	Do not advertise ETRN support in ESTMP EHLO reply if noetrn is
-		set in the PrivacyOptions option.  Fix from Ted Rule of
-		Flextech TV.
-	Log invalid persistent host status file lines instead of
-		bouncing the message.  Problem noted by David Lindes of
-		DaveLtd Enterprises.
-	Move creation of empty sendmail.st file from installation to
-		compilation.  Installation may be done from a read-only
-		mount.  Fix from Bryan Costales of InfoBeat, Inc. and Ric
-		Anderson of the Oasis Research Center, Inc.
-	Enforce the maximum number of User Database entries limit.  Problem
-		noted by Gary Buchanan of Credence Systems Inc.
-	Allow dead.letter files in root's home directory.  Problem noted
-		by Anna Ullman of Sun Microsystems.
-	Program deliveries in forward files could be marked unsafe if
-		any directory listed in the ForwardPath option did not
-		exist.  Problem noted by Jorg Bielak of Coastal Web Online.
-	Do not trust the length of the address structure returned by
-		gethostbyname().  Problem noted by Chris Evans of Oxford
-		University.
-	If the SIZE= MAIL From: ESMTP parameter is too large, use the
-		5.3.4 DSN status code instead of 5.2.2.  Similarly, for
-		non-local deliveries, if the message is larger than the
-		mailer maximum message size, use 5.3.4 instead of 5.2.3.

-8.9.0/8.9.0	1998/05/19
-	SECURITY: To prevent users from reading files not normally
-		readable, sendmail will no longer open forward, :include:,
-		class, ErrorHeader, or HelpFile files located in unsafe
-		(i.e., group or world writable) directory paths.  Sites
-		which need the ability to override security can use the
-		DontBlameSendmail option.  See the README file for more
-		information.
-	SECURITY: Problems can occur on poorly managed systems, specifically,
-		if maps or alias files are in world writable directories.
-		This fixes the change added to 8.8.6 to prevent links in these
-		world writable directories.
-	SECURITY: Make sure ServiceSwitchFile option file is not a link if
-		it is in a world writable directory.
-	SECURITY: Never pass a tty to a mailer -- if a mailer can get at the
-		tty it may be able to push bytes back to the senders input.
-		Unfortunately this breaks -v mode.  Problem noted by
-		Wietse Venema of the Global Security Analysis Lab at
-		IBM T.J. Watson Research.
-	SECURITY: Empty group list if DontInitGroups is set to true to
-		prevent program deliveries from picking up extra group
-		privileges.  Problem reported by Wolfgang Ley of DFN-CERT.
-	SECURITY: The default value for DefaultUser is now set to the uid and
-		gid of the first existing user mailnull, sendmail, or daemon
-		that has a non-zero uid.  If none of these exist, sendmail
-		reverts back to the old behavior of using uid 1 and gid 1.
-		This is a security problem for Linux which has chosen that
-		uid and gid for user bin instead of daemon.  If DefaultUser
-		is set in the configuration file, that value overrides this
-		default.
-	SECURITY: Since 8.8.7, the check for non-set-user-ID binaries
-		interfered with setting an alternate group id for the
-		RunAsUser option.  Problem noted by Randall Winchester of
-		the University of Maryland.
-	Add support for Berkeley DB 2.X.  Based on patch from John Kennedy
-		of Cal State University, Chico.
-	Remove support for OLD_NEWDB (pre-1.5 version of Berkeley DB).  Users
-		which previously defined OLD_NEWDB=1 must now upgrade to the
-		current version of Berkeley DB.
-	Added support for regular expressions using the new map class regex.
-		From Jan Krueger of Unix-AG of University of Hannover.
-	Support for BIND 8.1.1's hesiod for hesiod maps and hesiod
-		UserDatabases from Randall Winchester of the University
-		of Maryland.
-	Allow any shell for user shell on program deliveries on V1
-		configurations for backwards compatibility on machines which
-		do not have getusershell().  Fix from John Beck of Sun
-		Microsystems.
-	On operating systems which change the process title by reusing the
-		argument vector memory, sendmail could corrupt memory if the
-		last argument was either "-q" or "-d".  Problem noted by
-		Frank Langbein of the University of Stuttgart.
-	Support Local Mail Transfer Protocol (LMTP) between sendmail and
-		mail.local on the F=z flag.
-	Macro-expand the contents of the ErrMsgFile.  Previously this was
-		only done if you had magic characters (0x81) to indicate
-		macro expansion.  Now $x will be expanded.  This means that
-		real dollar signs have to be backslash escaped.
-	TCP Wrappers expects "unknown" in the hostname argument if the
-		reverse DNS lookup for the incoming connection fails.
-		Problem noted by Randy Grimshaw of Syracuse University and
-		Wietse Venema of the Global Security Analysis Lab at
-		IBM T.J. Watson Research.
-	DSN success bounces generated from an invocation of sendmail -t
-		would be sent to both the sender and MAILER-DAEMON.
-		Problem noted by Claus Assmann of
-		Christian-Albrechts-University of Kiel.
-	Avoid "Error 0" messages on delivery mailers which exit with a
-		valid exit value such as EX_NOPERM.  Fix from Andreas Luik
-		of ISA Informationssysteme GmbH.
-	Tokenize $&x expansions on right hand side of rules.  This eliminates
-		the need to use tricks like $(dequote "" $&{client_name} $)
-		to cause the ${client_name} macro to be properly tokenized.
-	Add the MaxRecipientsPerMessage option: this limits the number of
-		recipients that will be accepted in a single SMTP
-		transaction.  After this number is reached, sendmail
-		starts returning "452 Too many recipients" to all RCPT
-		commands.  This can be used to limit the number of recipients
-		per envelope (in particular, to discourage use of the server
-		for spamming).  Note: a better approach is to restrict
-		relaying entirely.
-	Fixed pointer initialization for LDAP lmap struct, fixed -s option
-		to ldapx map and added timeout for ldap_open call to
-		avoid hanging sendmail in the event of hung LDAP servers.
-		Patch from Booker Bense of Stanford University.
-	Allow multiple -qI, -qR, or -qS queue run limiters.  For example,
-		'-qRfoo -qRbar' would deliver mail to recipients with foo or
-		bar in their address.  Patch from Allan E Johannesen of
-		Worcester Polytechnic Institute.
-	The bestmx map will now return a list of the MX servers for a host if
-		passed a column delimiter via the -z map flag.  This can be
-		used to check if the server is an MX server for the recipient
-		of a message.  This can be used to help prevent relaying.
-		Patch from Mitchell Blank Jr of Exec-PC.
-	Mark failures for the *file* mailer and return bounce messages to the
-		sender for those failures.
-	Prevent bogus syslog timestamps on errors in sendmail.cf by
-		preserving the TZ environment variable until TimeZoneSpec
-		has been determined.  Problem noted by Ralf Hildebrandt of
-		Technical University of Braunschweig.  Patch from Per Hedeland
-		of Ericsson.
-	Print test input in address test mode when input is not from the tty
-		when the -v flag is given (i.e., sendmail -bt -v) to make
-		output easier to decipher.  Problem noted by Aidan Nichol
-		of Procter & Gamble.
-	The LDAP map -s flag was not properly parsed and the error message
-		given included the remainder of the arguments instead of
-		solely the argument in error.  Problem noted by Aidan Nichol
-		of Procter & Gamble.
-	New DontBlameSendmail option.  This option allows administrators to
-		bypass some of sendmail's file security checks at the expense
-		of system security.  This should only be used if you are
-		absolutely sure you know the consequences.  The available
-		DontBlameSendmail options are:
-			Safe
-			AssumeSafeChown
-			ClassFileInUnsafeDirPath
-			ErrorHeaderInUnsafeDirPath

-	New DontProbeInterfaces option to turn off the inclusion of all the
-		interface names in $=w on startup.  In particular, if you
-		have lots of virtual interfaces, this option will speed up
-		startup.  However, unless you make other arrangements, mail
-		sent to those addresses will be bounced.
-	Automatically create alias databases if they don't exist and
-		AutoRebuildAliases is set.
-	Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command.
-		Suggested by Christophe Wolfhugel of the Institut Pasteur.
-	Add PrivacyOptions=noverb flag to disable the SMTP VERB command.
-	When determining the client host name ($&{client_name} macro), do
-		a forward (A) DNS lookup on the result of the PTR lookup
-		and compare results.  If they differ or if the PTR lookup
-		fails, &{client_name} will contain the IP address
-		surrounded by square brackets (e.g., [127.0.0.1]).
-	New map flag: -Tx appends "x" to lookups that return temporary failure
-		(i.e, it is like -ax for the temporary failure case, in
-		contrast to the success case).
-	New syntax to do limited checking of header syntax.  A config line
-		of the form:
-			HHeader: $>Ruleset
-		causes the indicated Ruleset to be invoked on the Header
-		when read.  This ruleset works like the check_* rulesets --
-		that is, it can reject mail on the basis of the contents.
-	Limit the size of the HELO/EHLO parameter to prevent spammers
-		from hiding their connection information in Received:
-		headers.
-	When SingleThreadDelivery is active, deliveries to locked hosts
-		are skipped.  This will cause the delivering process to
-		try the next MX host or queue the message if no other MX
-		hosts are available.  Suggested by Alexander Litvin.
-	The [FILE] mailer type now delivers to the file specified in the
-		A= equate of the mailer definition instead of $u.  It also
-		obeys all of the F= mailer flags such as the MIME
-		7/8 bit conversion flags.  This is useful for defining
-		a mailer which delivers to the same file regardless of the
-		recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail).
-	Do not assume the identity of a remote connection is root@localhost
-		if the remote connection closes the socket before the
-		remote identity can be queried.
-	Change semantics of the F=S mailer flag back to 8.7.5 behavior.
-		Some mailers, including procmail, require that the real
-		uid is left unchanged by sendmail.  Problem noted by Per
-		Hedeland of Ericsson.
-	No longer is the src/obj*/Makefile selected from a large list -- it
-		is now generated using the information in BuildTools/OS/ --
-		some of the details are determined dynamically via
-		BuildTools/bin/configure.sh.
-	The other programs in the sendmail distribution -- mail.local,
-		mailstats, makemap, praliases, rmail, and smrsh -- now use
-		the new Build method which creates an operating system
-		specific Makefile using the information in BuildTools.
-	Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e.,
-		a failure on one message won't affect future messages to the
-		same host).  This is necessary if the remote host sends
-		a 451 error if the domain of the sender does not resolve
-		as is common in anti-spam configurations.  Problem noted
-		by Mitchell Blank Jr of Exec-PC.
-	New "discard" mailer for check_* rulesets and header checking
-		rulesets.  If one of the above rulesets resolves to the
-		$#discard mailer, the commands will be accepted but the
-		message will be completely discarded after it is accepting.
-		This means that even if only one of the recipients
-		resolves to the $#discard mailer, none of the recipients
-		will receive the mail.  Suggested by Brian Kantor.
-	All but the last cloned envelope of a split envelope were queued
-		instead of being delivered.  Problem noted by John Caruso
-		of CNET: The Computer Network.
-	Fix deadlock situation in persistent host status file locking.
-	Syslog an error if a user forward file could not be read due to
-		an error.  Patch from John Beck of Sun Microsystems.
-	Use the first name returned on machine lookups when canonifying a
-		hostname via NetInfo.  Patch from Timm Wetzel of GWDG.
-	Clear the $&{client_addr}, $&{client_name}, and $&{client_port}
-		macros when delivering a bounce message to prevent
-		rejection by a check_compat ruleset which uses these macros.
-		Problem noted by Jens Hamisch of AgiX Internetservices GmbH.
-	If the check_relay ruleset resolves to the the error mailer, the
-		error in the $: portion of the resolved triplet is used
-		in the rejection message given to the remote machine.
-		Suggested by Scott Gifford of The Internet Ramp.
-	Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros
-		before calling the check_relay ruleset.  Suggested by Scott
-		Gifford of The Internet Ramp.
-	Sendmail would get a segmentation fault if a mailer exited with an
-		exit code of 79.  Problem noted by Aaron Schrab of ExecPC
-		Internet.  Fix from Christophe Wolfhugel of the Pasteur
-		Institute.
-	Separate snprintf/vsnprintf routines into separate file for use by
-		mail.local.
-	Allow multiple map lookups on right hand side, e.g.,
-		R$*	$( host $1 $) $| $( passwd $1 $).  Patch from
-		Christophe Wolfhugel of the Pasteur Institute.
-	Properly generate success DSN messages if requested for aliases
-		which have owner- aliases.  Problem noted by Kari Hurtta
-		of the Finnish Meteorological Institute.
-	Properly display delayed-expansion macros ($&{macroname}) in
-		address test mode (-bt).  Problem noted by Bryan Costales
-		of InfoBeat, Inc.
-	-qR could sometimes match names incorrectly.  Problem noted by
-		Lutz Euler of Lavielle EDV Systemberatung GmbH & Co.
-	Include a magic number and version in the StatusFile for the
-		mailstats command.
-	Record the number of rejected and discarded messages in the
-		StatusFile for display by the mailstats command.  Patch
-		from Randall Winchester of the University of Maryland.
-	IDENT returns where the OSTYPE field equals "OTHER" now list the
-		user portion as IDENT:username@site instead of
-		username@site to differentiate the two.  Suggested by
-		Kari Hurtta of the Finnish Meteorological Institute.
-	Enforce timeout for LDAP queries.  Patch from Per Hedeland of
-		Ericsson.
-	Change persistent host status filename substitution so '/' is
-		replaced by ':' instead of '|' to avoid clashes.  Also
-		avoid clashes with hostnames with leading dots.  Fix from
-		Mitchell Blank Jr. of Exec-PC.
-	If the system lock table is full, only attempt to create a new
-		queue entry five times before giving up.  Previously, it
-		was attempted indefinitely which could cause the partition
-		to run out of inodes.  Problem noted by Suzie Weigand of
-		Stratus Computer, Inc.
-	In verbose mode, warn if the sendmail.cf version is less than the
-		currently supported version.
-	Sorting for QueueSortOrder=host is now case insensitive.  Patch
-		from Randall S. Winchester of the University of Maryland.
-	Properly quote a full name passed via the -F command line option,
-		the Full-Name: header, or the NAME environment variable if
-		it contains characters which must be quoted.  Problem noted
-		by Kari Hurtta of the Finnish Meteorological Institute.
-	Avoid possible race condition that unlocked a mail job before
-		releasing the transcript file on systems that use flock(2).
-		In some cases, this might result in a "Transcript Unavailable"
-		message in error bounces.
-	Accept SMTP replies which contain only a reply code and no
-		accompanying text.  Problem noted by Fernando Fraticelli of
-		Digital Equipment Corporation.
-	Portability:
-		AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura
-			of Kyoto University.
-		AIX 4.2 requires <userpw.h> before <usersec.h>.  Patch from
-			Randall S. Winchester of the University of
-			Maryland.
-		AIX 4.3 from Valdis Kletnieks of Virginia Tech CNS.
-		CRAY T3E from Manu Mahonen of Center for Scientific Computing
-			in Finland.
-		Digital UNIX now uses statvfs for determining free
-			disk space.  Patch from Randall S. Winchester of
-			the University of Maryland.
-		HP-UX 11.x from Richard Allen of Opin Kerfi HF and
-			Regis McEwen of Progress Software Corporation.
-		IRIX 64 bit fixes from Kari Hurtta of the Finnish
-			Meteorological Institute.
-		IRIX 6.2 configuration fix for mail.local from Michael Kyle
-			of CIC/Advanced Computing Laboratory.
-		IRIX 6.5 from Thomas H Jones II of SGI.
-		IRIX 6.X load average code from Bob Mende of SGI.
-		QNX from Glen McCready <glen@qnx.com>.
-		SCO 4.2 and 5.x use /usr/bin instead of /usr/ucb for links
-			to sendmail.  Install with group bin instead of kmem
-			as kmem does not exist.  From Guillermo Freige of
-			Gobernacion de la Pcia de Buenos Aires and Paul
-			Fischer of BTG, Inc.
-		SunOS 4.X does not include memmove().  Patch from
-			Per Hedeland of Ericsson.
-		SunOS 5.7 includes getloadavg() function for determining
-			load average.  Patch from John Beck of Sun
-			Microsystems.
-	CONFIG: Increment version number of config file.
-	CONFIG: add DATABASE_MAP_TYPE to set the default type of database
-		map for the various maps.  The default is hash.  Patch from
-		Robert Harker of Harker Systems.
-	CONFIG: new confEBINDIR m4 variable for defining the executable
-		directory for certain programs.
-	CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for
-		local mail delivery.  By the default, /usr/libexec/mail.local
-		is used.  This is expected to be the mail.local shipped
-		with 8.9 which is LMTP capable.  The path is based on the
-		new confEBINDIR m4 variable.
-	CONFIG: Use confEBINDIR in determining path to smrsh for
-		FEATURE(smrsh).  Note that this changes the default from
-		/usr/local/etc/smrsh to /usr/libexec/smrsh.  To obtain the
-		old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh).
-	CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to
-		include $z/.forward.$w+$h and $z/.forward+$h which allow
-		the user to setup different .forward files for
-		user+detail addressing.
-	CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES,
-		and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage,
-		DontProbeInterfaces, and DontBlameSendmail options.
-	CONFIG: by default do not allow relaying (that is, accepting mail
-		from outside your domain and sending it to another host
-		outside your domain).
-	CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from
-		any site to any site.
-	CONFIG: new FEATURE(relay_entire_domain) allows any host in your
-		domain as defined by the 'm' class ($=m) to relay.
-	CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on
-		the MX records of the host portion of an incoming recipient.
-	CONFIG: new FEATURE(access_db) which turns on the access database
-		feature.  This database gives you the ability to allow
-		or refuse to accept mail from specified domains for
-		administrative reasons.  By default, names that are listed
-		as "OK" in the access db are domain names, not host names.
-	CONFIG: new confCR_FILE m4 variable for defining the name of the file
-		used for class 'R'.  Defaults to /etc/mail/relay-domains.
-	CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file)
-		to add items to class 'R' ($=R) for hosts allowed to relay.
-	CONFIG: new FEATURE(relay_hosts_only) to change the behavior
-		of FEATURE(access_db) and class 'R' to lookup individual
-		host names only.
-	CONFIG: new FEATURE(loose_relay_check).  Normally, if a recipient
-		using % addressing is used, e.g.  user%site@othersite,
-		and othersite is in class 'R', the check_rcpt ruleset
-		will strip @othersite and recheck user@site for relaying.
-		This feature changes that behavior.  It should not be
-		needed for most installations.
-	CONFIG: new FEATURE(relay_local_from) to allow relaying if the
-		domain portion of the mail sender is a local host.  This
-		should only be used if absolutely necessary as it opens
-		a window for spammers.  Patch from Randall S. Winchester of
-		the University of Maryland.
-	CONFIG: new FEATURE(blacklist_recipients) turns on the ability to
-		block incoming mail destined for certain recipient
-		usernames, hostnames, or addresses.
-	CONFIG: By default, MAIL FROM: commands in the SMTP session will be
-		refused if the host part of the argument to MAIL FROM: cannot
-		be located in the host name service (e.g., DNS).
-	CONFIG: new FEATURE(accept_unresolvable_domains) accepts
-		unresolvable hostnames in MAIL FROM: SMTP commands.
-	CONFIG: new FEATURE(accept_unqualified_senders) accepts
-		MAIL FROM: senders which do not include a domain.
-	CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the
-		Realtime Blackhole List.  You can specify the RBL name
-		server to contact by specifying it as an optional argument.
-		The default is rbl.maps.vix.com.  For details, see
-		http://maps.vix.com/rbl/.
-	CONFIG: Call Local_check_relay, Local_check_mail, and
-		Local_check_rcpt from check_relay, check_mail, and
-		check_rcpt.  Users with local rulesets should place the
-		rules using LOCAL_RULESETS.  If a Local_check_* ruleset
-		returns $#OK, the message is accepted.  If the ruleset
-		returns a mailer, the appropriate action is taken, else
-		the return of the ruleset is ignored.
-	CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by
-		default to support file, :include:, and program deliveries.
-	CONFIG: Remove the default for confDEF_USER_ID so the binary can
-		pick the proper default value.  See the SECURITY note
-		above for more information.
-	CONFIG: FEATURE(nodns) now warns the user that the feature is a
-		no-op.  Patch from Kari Hurtta of the Finnish
-		Meteorological Institute.
-	CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to
-		daemon since DEC's /bin/mail will drop the envelope
-		sender if run as mailnull.  See the Digital UNIX section
-		of src/README for more information.  Problem noted by
-		Kari Hurtta of the Finnish Meteorological Institute.
-	CONFIG: .cf files are now stored in the same directory with the
-		.mc files instead of in the obj directory.
-	CONFIG: New options confSINGLE_LINE_FROM_HEADER,
-		confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for
-		setting SingleLineFromHeader, AllowBogusHELO, and
-		MustQuoteChars respectively.
-	MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.  This
-		SMTP-like protocol allows detailed reporting of delivery
-		status on a per-user basis.  Code donated by John Myers of
-		CMU (now of Netscape).
-	MAIL.LOCAL: HP-UX support from Randall S. Winchester of the
-		University of Maryland.  NOTE: mail.local is not
-		compatible with the stock HP-UX mail format.  Be sure to
-		read mail.local/README.
-	MAIL.LOCAL: Prevent other mail delivery agents from stealing a
-		mailbox lock.  Patch from Randall S. Winchester of the
-		University of Maryland.
-	MAIL.LOCAL: glibc portability from John Kennedy of Cal State
-		University, Chico.
-	MAIL.LOCAL: IRIX portability from Kari Hurtta of the Finnish
-		Meteorological Institute.
-	MAILSTATS: Display the number of rejected and discarded messages
-		in the StatusFile.  Patch from Randall Winchester of the
-		University of Maryland.
-	MAKEMAP: New -s flag to ignore safety checks on database map files
-		such as linked files in world writable directories.
-	MAKEMAP: Add support for Berkeley DB 2.X.  Remove OLD_NEWDB support.
-	PRALIASES: Add support for Berkeley DB 2.X.
-	PRALIASES: Do not automatically include NDBM support.  Problem
-		noted by Ralf Hildebrandt of the Technical University of
-		Braunschweig.
-	RMAIL: Improve portability for other platforms.  Patches from
-		Randall S. Winchester of the University of Maryland and
-		Kari Hurtta of the Finnish Meteorological Institute.

-8.8.8/8.8.8	1997/10/24
-	If the check_relay ruleset failed, the relay= field was logged
-		incorrectly.  Problem noted by Kari Hurtta of the Finnish
-		Meteorological Institute.
-	If /usr/tmp/dead.letter already existed, sendmail could not
-		add additional bounces to it.  Problem noted by Thomas J.
-		Arseneault of SRI International.
-	If an SMTP mailer used a non-standard port number for the outgoing
-		connection, it would be displayed incorrectly in verbose mode.
-		Problem noted by John Kennedy of Cal State University, Chico.
-	Log the ETRN parameter specified by the client before altering them
-		to internal form.  Suggested by Bob Kupiec of GES-Verio.
-	EXPN and VRFY SMTP commands on malformed addresses were logging as
-		User unknown with bogus delay= values.  Change them to log
-		the same as compliant addresses.  Problem noted by Kari E.
-		Hurtta of the Finnish Meteorological Institute.
-	Ignore the debug resolver option unless using sendmail debug trace
-		option for resolver.  Problem noted by Greg Nichols of Wind
-		River Systems.
-	If SingleThreadDelivery was enabled and the remote server returned a
-		protocol error on the DATA command, the connection would be
-		closed but the persistent host status file would not be
-		unlocked so other sendmail processes could not deliver to
-		that host.  Problem noted by Peter Wemm of DIALix.
-	If queueing up a message due to an expensive mailer, don't increment
-		the number of delivery attempts or set the last delivery
-		attempt time so the message will be delivered on the next
-		queue run regardless of MinQueueAge.  Problem noted by
-		Brian J. Coan of the Institute for Global Communications.
-	Authentication warnings of "Processed from queue _directory_" and
-		"Processed by _username_ with -C _filename_" would be logged
-		with the incorrect timestamp.  Problem noted by Kari E. Hurtta
-		of the Finnish Meteorological Institute.
-	Use a better heuristic for detecting GDBM.
-	Log null connections on dropped connections.  Problem noted by
-		Jon Lewis of Florida Digital Turnpike.
-	If class dbm maps are rebuilt, sendmail will now detect this and
-		reopen the map.  Previously, they could give stale
-		results during a single message processing (but would
-		recover when the next message was received).  Fix from
-		Joe Pruett of Q7 Enterprises.
-	Do not log failures such as "User unknown" on -bv or SMTP VRFY
-		requests.  Problem noted by Kari E. Hurtta of the
-		Finnish Meteorological Institute.
-	Do not send a bounce message back to the sender regarding bad
-		recipients if the SMTP connection is dropped before the
-		message is accepted.  Problem noted by Kari E. Hurtta of the
-		Finnish Meteorological Institute.
-	Use "localhost" instead of "[UNIX: localhost]" when connecting to
-		sendmail via a UNIX pipe.  This will allow rulesets using
-		$&{client_name} to process without sending the string through
-		dequote.  Problem noted by Alan Barrett of Internet Africa.
-	A combination of deferred delivery mode, a double bounce situation,
-		and the inability to save a bounce message to
-		/var/tmp/dead.letter would cause sendmail to send a bounce
-		to postmaster but not remove the offending envelope from the
-		queue causing it to create a new bounce message each time the
-		queue was run.  Problem noted by Brad Doctor of Net Daemons
-		Associates.
-	Remove newlines from hostname information returned via DNS.  There are
-		no known security implications of newlines in hostnames as
-		sendmail filters newlines in all vital areas; however, this
-		could cause confusing error messages.
-	Starting with sendmail 8.8.6, mail sent with the '-t' option would be
-		rejected if any of the specified addresses were bad.  This
-		behavior was modified to only reject the bad addresses and not
-		the entire message.  Problem noted by Jozsef Hollosi of
-		SuperNet, Inc.
-	Use Timeout.fileopen when delivering mail to a file.  Suggested by
-		Bryan Costales of InfoBeat, Inc.
-	Display the proper Final-Recipient on DSN messages for non-SMTP
-		mailers.  Problem noted by Kari E. Hurtta of the
-		Finnish Meteorological Institute.
-	An error in calculating the available space in the list of addresses
-		for logging deliveries could cause an address to be silently
-		dropped.
-	Include the initial user environment if sendmail is restarted via
-		a HUP signal.  This will give room for the process title.
-		Problem noted by Jon Lewis of Florida Digital Turnpike.
-	Mail could be delivered without a body if the machine does not
-		support flock locking and runs out of processes during
-		delivery.  Fix from Chuck Lever of the University of Michigan.
-	Drop recipient address from 251 and 551 SMTP responses per RFC 821.
-		Problem noted by Kari E. Hurtta of the Finnish Meteorological
-		Institute.
-	Make sure non-rebuildable database maps are opened before the
-		rebuildable maps (i.e., alias files) in case the database maps
-		are needed for verifying the left hand side of the aliases.
-		Problem noted by Lloyd Parkes of Victoria University.
-	Make sure sender RFC822 source route addresses are alias expanded for
-		bounce messages.  Problem noted by Juergen Georgi of
-		RUS University of Stuttgart.
-	Minor lint fixes.
-	Return a temporary error instead of a permanent error if an LDAP map
-		search returns an error.  This will allow sequenced maps which
-		use other LDAP servers to be checked.  Fix from Booker Bense
-		of Stanford University.
-	When automatically converting from quoted printable to 8bit text do
-		not pad bare linefeeds with a space.  Problem noted by Theo
-		Nolte of the University of Technology Aachen, Germany.
-	Portability:
-		Non-standard C compilers may have had a problem compiling
-			conf.c due to a standard C external declaration of
-			setproctitle().  Problem noted by Ted Roberts of
-			Electronic Data Systems.
-		AUX: has a broken O_EXCL implementation.  Reported by Jim
-			Jagielski of jaguNET Access Services.
-		BSD/OS: didn't compile if HASSETUSERCONTEXT was defined.
-		Digital UNIX: Digital UNIX (and possibly others) moves
-			loader environment variables into the loader memory
-			area.  If one of these environment variables (such as
-			LD_LIBRARY_PATH) was the last environment variable,
-			an invalid memory address would be used by the process
-			title routine causing memory corruption.  Problem
-			noted by Sam Hartman of Mesa Internet Systems.
-		GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused
-			chownsafe() to always return 0 even if the OS does
-			not permit file giveaways.  Problem noted by
-			Yasutaka Sumi of The University of Tokyo.
-		IRIX6: Syslog buffer size set to 512 bytes.  Reported by
-			Gerald Rinske of Siemens Business Services VAS.
-		Linux: Pad process title with NULLs.  Problem noted by
-			Jon Lewis of Florida Digital Turnpike.
-		SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an

-			Problem noted by Chris Loelke of JetStream Internet
-			Services.
-		SINIX: Update for Makefile and syslog buffer size from Gerald
-			Rinske of Siemens Business Services VAS.
-		Solaris: Make sure HASGETUSERSHELL setting for SunOS is not

-	MAKEMAP: Use a better heuristic for detecting GDBM.

-8.8.7/8.8.7	1997/08/03
-	If using Berkeley DB on systems without O_EXLOCK (open a file with
-		an exclusive lock already set -- i.e., almost all systems
-		except 4.4-BSD derived systems), the initial attempt at
-		rebuilding aliases file if the database didn't already
-		exist would fail.  Patch from Raymund Will of LST Software
-		GmbH.
-	Bogus incoming SMTP commands would reset the SMTP conversation.
-		Problem noted by Fredrik Jönsson of the Royal Institute
-		of Technology, Stockholm.
-	Since TCP Wrappers includes setenv(), unsetenv(), and putenv(),
-		some environments could give "multiple definitions" for these
-		routines during compilation.  If using TCP Wrappers, assume
-		that these routines are included as though they were in the
-		C library.  Patch from Robert La Ferla.
-	When a NEWDB database map was rebuilt at the same time it was being
-		used by a queue run, the maps could be left locked for the
-		duration of the queue run, causing other processes to hang.
-		Problem noted by Kendall Libby of Shore.NET.
-	In some cases, NoRecipientAction=add-bcc was being ignored, so the
-		mail was passed on without any recipient header.  This could
-		cause problems downstream.  Problem noted by Xander Jansen
-		of SURFnet ExpertiseCentrum.
-	Give error when GDBM is used with sendmail.  GDBM's locking and
-		linking of the .dir and .pag files interferes with sendmail's
-		locking and security checks.  Problems noted by Fyodor
-		Yarochkin of the Kyrgyz Republic FreeNet.
-	Don't fsync qf files if SuperSafe option is not set.
-	Avoid extra calls to gethostbyname for addresses for which a
-		gethostbyaddr found no value.  Also, ignore any returns
-		from gethostbyaddr that look like a dotted quad.
-	If PTR lookup fails when looking up an SMTP peer, don't tag it as
-		"may be forged", since at the network level we pretty much
-		have to assume that the information is good.
-	In some cases, errors during an SMTP session could leave files
-		open or locked.
-	Better handling of missing file descriptors (0, 1, 2) on startup.
-	Better handling of non-set-user-ID binaries -- avoids certain obnoxious
-		errors during testing.
-	Errors in file locking of NEWDB maps had the incorrect file name
-		printed in the error message.
-	If the AllowBogusHELO option were set and an EHLO with a bad or
-		missing parameter were issued, the EHLO behaved like a HELO.
-	Load limiting never kicked in for incoming SMTP transactions if the
-		DeliveryMode=background and any recipient was an alias or
-		had a .forward file.  From Nik Conwell of Boston University.
-	On some non-Posix systems, the decision of whether chown(2) permits
-		file giveaway was undefined.  From Tetsu Ushijima of the
-		Tokyo Institute of Technology.
-	Fix race condition that could cause the body of a message to be
-		lost (so only the header was delivered).  This only occurs
-		on systems that do not use flock(2), and only when a queue
-		runner runs during a critical section in another message
-		delivery.  Based on a patch from Steve Schweinhart of
-		Results Computing.
-	If a qf file was found in a mail queue directory that had a problem
-		(wrong ownership, bad format, etc.) and the file name was
-		exactly MAXQFNAME bytes long, then instead of being tried
-		once, it would be tried on every queue run.  Problem noted
-		by Bryan Costales of Mercury Mail.
-	If the system supports an st_gen field in the status structure,
-		include it when reporting that a file has changed after open.
-		This adds a new compile flag, HAS_ST_GEN (0/1 option).
-		This out to be checked as well as reported, since it is
-		theoretically possible for an attacker to remove a file after
-		it is opened and replace it with another file that has the
-		same i-number, but some filesystems (notably AFS) return
-		garbage in this field, and hence always look like the file
-		has changed.  As a practical matter this is not a security
-		problem, since the files can be neither hard nor soft links,
-		and on no filesystem (that I am aware of) is it possible to
-		have two files on the same filesystem with the same i-number
-		simultaneously.
-	Delete the root Makefile from the distribution -- it is only for
-		use internally, and does not work at customer sites.
-	Fix botch that caused the second MAIL FROM: command in a single
-		transaction to clear the entire transaction.  Problem
-		noted by John Kennedy of Cal State University, Chico.
-	Work properly on machines that have _PATH_VARTMP defined without
-		a trailing slash.  (And a pox on vendors that decide to
-		ignore the established conventions!)  Problem noted by
-		Gregory Neil Shapiro of WPI.
-	Internal changes to make it easier to add another protocol family
-		(intended for IPv6).  Patches are from John Kennedy of
-		CSU Chico.
-	In certain cases, 7->8 bit MIME decoding of Base64 text could leave
-		an extra space at the beginning of some lines.  Problem
-		noted by Charles Karney of Princeton University; fix based
-		on a patch from Christophe Wolfhugel.
-	Portability:
-		Allow _PATH_VENDOR_CF to be set in Makefile for consistency
-			with the _Sendmail_ book, 2nd edition.  Note that
-			the book is actually wrong: _PATH_SENDMAILCF should
-			be used instead.
-		AIX 3.x: Include <sys/select.h>.  Patch from Gene Rackow
-			of Argonne National Laboratory.
-		OpenBSD from from Paul DuBois of the University of Wisconsin.
-		RISC/os 4.0 from Paul DuBois of the University of Wisconsin.
-		SunOS: Include <memory.h> to fix warning from util.c.  From
-			James Aldridge of EUnet Ltd.
-		Solaris: Change STDIR (location of status file) to /etc/mail
-			in Makefiles.
-		Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from
-			Makefiles.  Use NEWDB on Linux instead.
-		NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl
-			exists but behaves differently than other OSes.
-			Add SIOCGIFNUM_IS_BROKEN compile flag to get
-			around the problem.  Problem noted by Tom Moore of
-			NCR Corp.
-		HP-UX 9.x: fix compile warnings for old select API.  Problem
-			noted by Tom Smith of Digital Equipment Corp.
-		UnixWare 2.x: compile warnings on offsetof macro.  Problem
-			noted by Tom Good of the Community Access Information
-			Resource Network
-		SCO 4.2: compile problems caused by a change in the type of
-			the "length" parameters passed to accept, getpeername,
-			getsockname, and getsockopt.  Adds new compile flags
-			SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.  Problem reported
-			by Tom Good of St. Vincent's North Richmond Community
-			Mental Health Center Residential Services.
-		AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.
-			Suggested by Brett Hogden of Rochester Gas & Electric
-			Corp.
-		Linux: avoid compile problem for versions of <setjmp.h> that
-			#define both setjmp and longjmp.  Problem pointed out
-			by J.R. Oldroyd of TerraNet.
-		CONFIG: SCO UnixWare 2.1: Support for OSTYPE(sco-uw-2.1)
-			from Christopher Durham of SCO.
-		CONFIG: NEXTSTEP: define confCW_FILE to
-			/etc/sendmail/sendmail.cw to match the usual
-			configuration.  Patch from Dennis Glatting of
-			PlainTalk.
-	CONFIG: MAILER(fax) called a program that hasn't existed for a long
-		time.  Convert to use the HylaFAX 4.0 conventions.  Suggested
-		by Harry Styron.
-	CONFIG: Improve sample anti-spam rulesets in cf/cf/knecht.mc.  These
-		are the rulesets in use on sendmail.org.
-	MAKEMAP: give error on GDBM files.
-	MAIL.LOCAL: Make error messages a bit more explicit, for example,
-		telling more details on what actually changed when "file
-		changed after open".
-	CONTRIB: etrn.pl: Ignore comments in Fw files.  Support multiple Fw
-		files.
-	CONTRIB: passwd-to-alias.pl: Handle 8 bit characters and '-'.
-	NEW FILES:
-		src/Makefiles/Makefile.OpenBSD
-		src/Makefiles/Makefile.RISCos.4_0

-	    *************************************************************
-	    * The extensive assistance of Gregory Neil Shapiro of WPI	*
-	    * in preparing this release is gratefully appreciated.	*
-	    * Sun Microsystems has also provided resources toward	*
-	    * continued sendmail development.				*
-	    *************************************************************
-	SECURITY: A few systems allow an open with the O_EXCL|O_CREAT open
-		mode bits set to create a file that is a symbolic link that
-		points nowhere.  This makes it possible to create a root
-		owned file in an arbitrary directory by inserting the symlink
-		into a writable directory after the initial lstat(2) check
-		determined that the file did not exist.  The only verified
-		example of a system having these odd semantics for O_EXCL
-		and symbolic links was HP-UX prior to version 9.07.  Most
-		systems do not have the problem, since a exclusive create
-		of a file disallows symbolic links.  Systems that have been
-		verified to NOT have the problem include AIX 3.x, *BSD,
-		DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris,
-		and Ultrix.  This is a potential exposure on systems that
-		have this bug and which do not have a MAILER-DAEMON alias
-		pointing at a legitimate account, since this will cause old
-		mail to be dropped in /var/tmp/dead.letter.
-	SECURITY: Problems can occur on poorly managed systems, specifically,
-		if maps or alias files are in world writable directories.
-		If your system has alias maps in writable directories, it
-		is potentially possible for an attacker to replace the .db
-		(or .dir and .pag) files by symbolic links pointing at
-		another database; this can be used either to expose
-		information (e.g., by pointing an alias file at /etc/spwd.db
-		and probing for accounts), or as a denial-of-service attack
-		(by trashing the password database).  The fix disallows
-		symbolic links entirely when rebuilding alias files or on
-		maps that are in writable directories, and always warns on
-		writable directories; 8.9 will probably consider writable
-		directories to be fatal errors.  This does not represent an
-		exposure on systems that have alias files in unwritable
-		system directories.
-	SECURITY: disallow .forward or :include: files that are links (hard
-		or soft) if the parent directory (or any directory in the
-		path) is writable by anyone other than the owner.  This is
-		similar to the previous case for user files.  This change
-		should not affect most systems, but is necessary to prevent
-		an attacker who can write the directory from pointing such
-		files at other files that are readable only by the owner.
-	SECURITY: Tighten safechown rules: many systems will say that they
-		have a safe (restricted to root) chown even on files that
-		are mounted from another system that allows owners to give
-		away files.  The new rules are very strict, trusting file
-		ownership only in those few cases where the system has
-		been verified to be at least as paranoid as necessary.
-		However, it is possible to relax the rules to partially
-		trust the ownership if the directory path is not world or
-		group writable.  This might allow someone who has a legitimate
-		:include: file (referenced directly from /etc/aliases) to
-		become another non-root user if the :include: file is in a
-		non-writable directory on an NFS-mounted filesystem where
-		the local system says that giveaway is denied but it is
-		actually permitted.  I believe this to be a very small set
-		of cases.  If in doubt, do not point :include: aliases at
-		NFS-mounted filesystems.
-	SECURITY: When setting a numeric group id using the RunAsUser option
-		(e.g., "O RunAsUser=10:20", the group id would not be set.
-		Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha
-		group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine.
-		The user id was still set properly.  Problem noted by Uli
-		Pralle of the Technical University of Berlin.
-	Save the initial gid set for use when checking for if the
-		PrivacyOptions=restrictmailq option is set.  Problem reported
-		by Wolfgang Ley of DFN-CERT.
-	Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a
-		failure on one message won't affect future messages to the
-		same host).
-	IP source route printing had an "off by one" error that would
-		affect any options that came after the route option.  Patch
-		from Theo de Raadt.
-	The "Message is too large" error didn't successfully bounce the error
-		back to the sender.  Problem reported by Stephen More of
-		PSI; patch from Gregory Neil Shapiro of WPI.
-	Change SMTP status code 553 to map into Extended code 5.1.0 (instead
-		of 5.1.3); it apparently gets used in multiple ways.
-		Suggested by John Myers of Portola Communications.
-	Fix possible extra null byte generated during collection if errors
-		occur at the beginning of the stream.  Patch contributed by
-		Andrey A. Chernov and Gregory Neil Shapiro.
-	Code changes to avoid possible reentrant call of malloc/free within
-		a signal handler.  Problem noted by John Beck of Sun
-		Microsystems.
-	Move map initialization to be earlier so that check_relay ruleset
-		will have the latest version of the map data.  Problem noted
-		by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro.
-	If there are fatal errors during the collection phase (e.g., message
-		too large) don't send the bogus message.
-	Avoid "cannot open xfAAA00000" messages when sending to aliases that
-		have errors and have owner- aliases.  Problem noted by Michael
-		Barber of MTU; fix from Gregory Neil Shapiro of WPI.
-	Avoid null pointer dereference on illegal Boundary= parameters in
-		multipart/mixed Content-Type: header.  Problem noted by
-		Richard Muirden of RMIT University.
-	Always print error messages during newaliases (-bi) even if the
-		ErrorMode is not set to "print".  Fix from Gregory Neil
-		Shapiro.
-	Test mode could core dump if you did a /map lookup in an optional map
-		that could not be opened.  Based on a fix from John Beck of
-		Sun Microsystems.
-	If DNS is misconfigured so that the last MX record tried points to
-		a host that does not have an A record, but other MX records
-		pointed to something reasonable, don't bounce the message
-		with a "host unknown" error.  Note that this should really
-		be fixed in the zone file for the domain.  Problem noted by
-		Joe Rhett of Navigist, Inc.
-	If a map fails (e.g., DNS times out) on all recipient addresses, mark
-		the message as having been tried; otherwise the next queue
-		run will not realize that this is a second attempt and will
-		retry immediately.  Problem noted by Bryan Costales of
-		Mercury Mail.
-	If the clock is set backwards, and a MinQueueAge is set, no jobs
-		will be run until the later setting of the clock is reached.
-		"Problem" (I use the term loosely) noted by Eric Hagberg of
-		Morgan Stanley.
-	If the load average rises above the cutoff threshold (above which
-		sendmail will not process the queue at all) during a queue
-		run, abort the queue run immediately.  Problem noted by
-		Bryan Costales of Mercury Mail.
-	The variable queue processing algorithm (based on the message size,
-		number of recipients, message precedence, and job age) was
-		non-functional -- either the entire queue was processed or
-		none of the queue was processed.  The updated algorithm
-		does no queue run if a single recipient zero size job will
-		not be run.
-	If there is a fatal ("panic") message that will cause sendmail to
-		die immediately, never hold the error message for future
-		printing.
-	Force ErrorMode=print in -bt mode so that all errors are printed
-		regardless of the setting of the ErrorMode option in the
-		configuration file.  Patch from Gregory Neil Shapiro.
-	New compile flag HASSTRERROR says that this OS has the strerror(3)
-		routine available in one of the libraries.  Use it in conf.h.
-	The -m (match only) flag now works on host class maps.
-	If class hash or btree maps are rebuilt, sendmail will now detect
-		this and reopen the map.  Previously, they could give
-		erroneous results during a single message processing
-		(but would recover when the next message was received).
-	Don't delete zero length queue files when doing queue runs until the
-		files are at least ten minutes old.  This avoids a potential
-		race condition: the creator creates the qf file, getting back
-		a file descriptor.  The queue runner locks it and deletes it
-		because it is zero length.  The creator then writes the
-		descriptor that is now for a disconnected file, and the
-		job goes away.  Based on a suggestion by Bryan Costales.
-	When determining the "validated" host name ($_ macro), do a forward
-		(A) DNS lookup on the result of the PTR lookup and compare
-		results.  If they differ or if the PTR lookup fails, tag the
-		address as "may be forged".
-	Log null connections (i.e., hosts that connect but do not do any
-		substantive activity on the connection before disconnecting;
-		"substantive" is defined to be MAIL, EXPN, VRFY, or ETRN.
-	Always permit "writes" to /dev/null regardless of the link count.
-		This is safe because /dev/null is special cased, and no open
-		or write is ever actually attempted.  Patch from Villy Kruse
-		of TwinCom.
-	If a message cannot be sent because of a 552 (exceeded storage
-		allocation) response to the MAIL FROM:<>, and a SIZE= parameter
-		was given, don't return the body in the bounce, since there
-		is a very good chance that the message will double-bounce.
-	Fix possible line truncation if a quoted-printable had an =00 escape
-		in the body.  Problem noted by Charles Karney of the Princeton
-		Plasma Physics Laboratory.
-	Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses.
-		Problem noted by Kari Hurtta of the Finnish Meteorological
-		Institute.
-	The MaxDaemonChildren option wasn't applying to queue runs as
-		documented.  Note that this increases the potential denial
-		of service problems with this option: an attacker can
-		connect many times, and thereby lock out queue runs as well
-		as incoming connections.  If you use this option, you should
-		run the "sendmail -bd" and "sendmail -q30m" jobs separately
-		to avoid this attack.  Failure to limit noted by Matthew
-		Dillon of BEST Internet Communications.
-	Always give a message in newaliases if alias files cannot be
-		opened instead of failing silently.  Suggested by Gregory
-		Neil Shapiro.  This change makes the code match the O'Reilly
-		book (2nd edition).
-	Some older versions of the resolver could return with h_errno == -1
-		if no name server could be reached, causing mail to bounce
-		instead of queueing.  Treat this like TRY_AGAIN.  Fix from
-		John Beck of SunSoft.
-	If a :include: file is owned by a user that does not have an entry
-		in the passwd file, sendmail could dereference a null pointer.
-		Problem noted by Satish Mynam of Sun Microsystems.
-	Take precautions to make sure that the SMTP protocol cannot get out
-		of sync if (for example) an alias file cannot be opened.
-	Fix a possible race condition that can cause a SIGALRM to come in
-		immediately after a SIGHUP, causing the new sendmail to die.
-	Avoid possible hang on SVr3 systems when doing child reaping.  Patch
-		from Villy Kruse of TwinCom.
-	Ignore improperly formatted SMTP reply codes.  Previously these were
-		partially processed, which could cause confusing error
-		returns.
-	Fix possible bogus pointer dereference when doing ldapx map lookups
-		on some architectures.
-	Portability:
-		A/UX: from Jim Jagielski of NASA/GSFC.
-		glibc: SOCK_STREAM was changed from a #define to an enum,
-			thus breaking #ifdef SOCK_STREAM.  Only option seems
-			to be to assume SOCK_STREAM if __GNU_LIBRARY__ is
-			defined.  Problem reported by A Sun of the University
-			of Washington.
-		Solaris: use SIOCGIFNUM to get the number of interfaces on
-			the system rather than guessing at compile time.
-			Patch contributed by John Beck of Sun Microsystems.
-		Intel Paragon: from Wendy Lin of Purdue University.
-		GNU Hurd: from Miles Bader of the GNU project.
-		RISC/os 4.50 from Harlan Stenn of PFCS Corporation.
-		ISC Unix: wait never returns if SIGCLD signals are blocked.
-			Unfortunately releasing them opens a race condition,
-			but there appears to be no fix for this.  Patch from
-			Gregory Neil Shapiro.
-		BIND 8.1 for IPv6 compatibility from John Kennedy.
-		Solaris: a bug in strcasecmp caused characters with the
-			high order bit set to apparently randomly match
-			letters -- for example, $| (0233) matches "i" and "I".
-			Problem noted by John Gregson of the University of
-			Cambridge.
-		IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x.  From
-			Kari Hurtta.
-		IRIX 6.x: Create Makefiles for systems that claim to be
-			IRIX64 but are 6.2 or higher (so use the regular
-			IRIX Makefile).
-		IRIX 6.x: Fix load average computation on 64 bit kernels.
-			Problem noted by Eric Hagberg of Morgan Stanley.
-	CONFIG: Some canonification was still done for UUCP-like addresses
-		even if FEATURE(nocanonify) was set.  Problem pointed out by
-		Brian Candler.
-	CONFIG: In some cases UUCP mailers wouldn't properly recognize all
-		local names as local.  Problem noted by Jeff Polk of BSDI;
-		fix provided by Gregory Neil Shapiro.
-	CONFIG: The "local:user" syntax entries in mailertables and other
-		"mailer:user" syntax locations returned an incorrect value
-		for the $h macro.  Problem noted by Gregory Neil Shapiro.
-	CONFIG: Retain "+detail" information when forwarding mail to a
-		MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY.  Patch from Philip
-		Guenther of Gustavus Adolphus College.
-	CONFIG: Make sure user+detail works for FEATURE(virtusertable);
-		rules are the same as for aliasing.  Based on a patch from
-		Gregory Neil Shapiro.
-	CONFIG: Break up parsing rules into several pieces; this should
-		have no functional change in this release, but makes it
-		possible to have better anti-spam rulesets in the future.
-	CONFIG: Disallow double dots in host names to avoid having the
-		HostStatusDirectory store status under the wrong name.
-		In some cases this can be used as a denial-of-service attack.
-		Problem noted by Ron Jarrell of Virginia Tech, patch from
-		Gregory Neil Shapiro.
-	CONFIG: Don't use F=m (multiple recipients per invocation) for
-		MAILER(procmail), but do pass F=Pn9 (include Return-Path:,
-		don't include From_, and convert to 8-bit).  Suggestions
-		from Kimmo Suominen and Roderick Schertler.
-	CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were
-		being masqueraded as though FEATURE(masquerade_entire_domain)
-		was specified, even when it wasn't.
-	MAIL.LOCAL: Solaris 2.6 has snprintf.  From John Beck of SunSoft.
-	MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't
-		"slip in" a symbolic link between the lstat(2) call and the
-		exclusive open.  This is only a problem on System V derived
-		systems that allow an exclusive create on files that are
-		symbolic links pointing nowhere.
-	MAIL.LOCAL: If the final mailbox close() failed, the user id was
-		not reset back to root, which on some systems would cause
-		later mailboxes to fail.  Also, any partial message would
-		not be truncated, which could result in repeated deliveries.
-		Problem noted by Bruce Evans via Peter Wemm (FreeBSD
-		developers).
-	MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0.  A similar
-		change to the sendmail map code was made in 8.8.3.  Problem
-		noted by Gregory Neil Shapiro.
-	MAKEMAP: Give warnings on file problems such as map files that are
-		symbolic links; although makemap is not set-user-ID root, it is
-		often run as root and hence has the potential for the same
-		sorts of problems as alias rebuilds.
-	MAKEMAP: Change compilation so that it will link properly on
-		NEXTSTEP.
-	CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf.
-		Accept an optional list of arguments following the server
-		name for the ETRN arguments to use (instead of $=w).  Other
-		miscellaneous bug fixes.  From Christian von Roques via
-		John Beck of Sun Microsystems.
-	CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta.  This
-		Perl script converts GECOS information in the /etc/passwd
-		file into aliases, allowing for faster access to full name
-		lookups; it is also clever about adding aliases (to root)
-		for system accounts.
-	NEW FILES:
-		src/safefile.c
-		cf/ostype/gnuhurd.m4
-		cf/ostype/irix6.m4
-		contrib/passwd-to-alias.pl
-		src/Makefiles/Makefile.IRIX64.6.1
-		src/Makefiles/Makefile.IRIX64.6.x
-	RENAMED FILES:
-		src/Makefiles/Makefile.IRIX.6.2 =>	Makefile.IRIX.6.x
-		src/Makefiles/Makefile.IRIX64 =>	Makefile.IRIX64.6.0
-
-8.8.5/8.8.5	1997/01/21
-	SECURITY: Clear out group list during startup.  Without this, sendmail
-		will continue to run with the group permissions of the caller,
-		even if RunAsUser is specified.
-	SECURITY: Make purgestat (-bH) be root-only.  This is not in response
-		to any known attack, but it's best to be conservative.
-		Suggested by Peter Wemm of DIALix.
-	SECURITY: Fix buffer overrun problem in MIME code that has possible
-		security implications.  Patch from Alex Garthwaite of the
-		University of Pennsylvania.
-	Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'")
-		would truncate the address after "Full".  Although the -f
-		syntax is incorrect (since it is in the envelope, it
-		shouldn't have comments and full names), the failure mode
-		was unnecessarily awful.
-	Fix a possible null pointer dereference when converting 8-bit data
-		to a 7-bit format.  Problem noted by Jim Hutchins of
-		Sandia National Labs and David James of British Telecom.
-	Clear out stale state that affected F=9 on SMTP mailers in queue
-		runs.  Although this really shouldn't be used (F=9 is for
-		final delivery only, and using it on an SMTP mailer makes
-		it possible for a message to be converted from 8->7->8->7
-		bits several times), it shouldn't have failed with a syserr.
-		Problem noted by Eric Hagberg of Morgan Stanley.
-	_Really_ fix the multiple :maildrop code in the user database
-		module.  Patch from Roy Mongiovi of Georgia Tech.
-	Let F lines in the configuration file actually read root-only
-		files if the configuration file is safe.  Based on a
-		patch from Keith Reynolds of SCO.
-	ETRN followed by QUIT would hold the connection open until the queue
-		run completed.  Problem noted by Truck Lewis of TDK
-		Semiconductor Corp.
-	It turns out that despite the documentation, the TCP wrappers library
-		does _not_ log rejected connections.  Do the logging ourselves.
-		Problem noted by Fletcher Mattox of the University of Texas
-		at Austin.
-	If sendmail finds a qf file in its queue directory that is an unknown
-		version (e.g., when backing out to an old version), the
-		error is reported on every queue run.  Change it to only
-		give the error once (and rename the qf => Qf).  Patch from
-		William A. Gianopoulos of Raytheon Company.
-	Start a new session when doing background delivery; currently it
-		ignored signals but didn't start a new signal, that caused
-		some problems if a background process tried to send mail
-		under certain circumstances.  Problem noted by Eric Hagberg
-		of Morgan Stanley; fix from Kari Hurtta.
-	Simplify test for skipping a queue run to just check if the current
-		load average is >= the queueing load average.  Previously
-		the check factored in some other parameters that caused it
-		to essentially never skip the queue run.  Patch from Bryan
-		Costales.
-	If the SMTP server is running in "nullserver" mode (that is, it is
-		rejecting all commands), start sleeping after MAXBADCOMMAND
-		(25) commands; this helps prevent a bad guy from putting
-		you into a tight loop as a denial-of-service attack.  Based
-		on an e-mail conversation with Brad Knowles of AOL.
-	Slow down when too many "light weight" commands have been issued;
-		this helps prevent a class of denial-of-service attacks.
-		The current values and defaults are:
-		    MAXNOOPCOMMANDS	20	NOOP, VERB, ONEX, XUSR
-		    MAXHELOCOMMANDS	3	HELO, EHLO
-		    MAXVRFYCOMMANDS	6	VRFY, EXPN
-		    MAXETRNCOMMANDS	8	ETRN
-		These will probably be configurable in a future release.
-	On systems that have uid_t typedefed to be an unsigned short, programs
-		that had the F=S flag and no U= equate would be invoked with
-		the real uid set to 65535 rather than being left unchanged.
-	In some cases, NOTIFY=NEVER was not being honored.  Problem noted
-		by Steve Hubert of the University of Washington, Seattle.
-	Mail that was Quoted-Printable encoded and had a soft line break on
-		the last line (i.e., an incomplete continuation) had the last
-		line dropped.  Since this appears to be illegal it isn't
-		clear what to do with it, but flushing the last line seems
-		to be a better "fail soft" approach.  Based on a patch from
-		Eric Hagberg.
-	If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a
-		bogus HELO command still causes the "Polite people say HELO
-		first" error message.  Problem pointed out by Chris Thomas
-		of UCLA; patch from John Beck of SunSoft.
-	Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set
-		in PrivacyOptions.  The -q shouldn't turn this command off.
-		Problem noted by Murray Kucherawy of Pacific Bell Internet;
-		based on a patch from Gregory Neil Shapiro of WPI.
-	Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation)
-		in a DATA transaction to be sticky; these can occur because
-		a message is too large, and smaller messages should still go
-		through.  Problem noted by Matt Dillon of Best Internet
-		Communications.
-	In some cases bounces were saved in /var/tmp/dead.letter even if they
-		had been successfully delivered to the envelope sender.
-		Problem noted Eric Hagberg of Morgan Stanley; solution from
-		Gregory Neil Shapiro of WPI.
-	Give better diagnostics on long alias lines.  Based on code contributed
-		by Patrick Gosling of the University of Cambridge.
-	Increase the number of virtual interfaces that will be probed for
-		alternate names.  Problem noted by Amy Rich of Shore.Net.
-	PORTABILITY:
-		UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from

-	CONFIG: It seems that I hadn't gotten the Received: line syntax
-		_just_right_ yet.  Tweak it again.  I'll omit the names
-		of the "contributors" (quantity two) in this one case.
-		As of now, NO MORE DISCUSSION about the syntax of the
-		Received: line.
-	CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E),
-		it never inserts that class into the output file.  Fix it
-		so it will honor EXPOSED_USER but will _not_ include root
-		automatically in this class.  Problem noted by Ronan KERYELL
-		of Centre de Recherche en Informatique de l'École Nationale
-		Supérieure des Mines de Paris (CRI-ENSMP).
-	CONFIG: Clean up handling of "local:" syntax in relay specifications
-		such as LUSER_RELAY.  This change permits the following
-		syntaxes:  ``local:'' will send to the same user on the
-		local machine (e.g., in a mailertable entry for "host",
-		``local:'' will cause an address addressed to user@host to
-		go to user on the local machone).  ``local:user'' will send
-		to the named user on the local machine.  ``local:user@host''
-		is equivalent to ``local:user'' (the host is ignored).  In
-		all cases, the original user@host is passed in $@ (i.e., the
-		detail information).  Inspired by a report from Michael Fuhr.
-	CONFIG: Strip quotes from the first word of an "error:" host
-		indication.  This lets you set (for example) the LUSER_RELAY
-		to be ``error:\"5.1.1\" Your Message Here''.  Note the use
-		of the \" so that the resulting string is properly quoted.
-		Problem noted by Gregory Neil Shapiro of WPI.
-	OP.ME: documentation was inconsistent about whether sendmail did a
-		NOOP or a RSET to probe the connection (it does a RSET).
-		Inconsistency noted by Deeran Peethamparam.
-	OP.ME: insert additional blank pages so it will print properly on
-		a duplex printer.  From Matthew Black of Cal State University,

-8.8.4/8.8.4	1996/12/02
-	SECURITY: under some circumstances, an attacker could get additional
-		permissions by hard linking to files that were group
-		writable by the attacker.  The solution is to disallow any
-		files that have hard links -- this will affect .forward,
-		:include:, and output files.  Problem noted by Terry
-		Kyriacopoulos of Interlog Internet Services.  As a
-		workaround, set UnsafeGroupWrites -- always a good idea.
-	SECURITY: the TryNullMXList (w) option should not be safe -- if it
-		is, it is possible to do a denial-of-service attack on
-		MX hosts that rely on the use of the null MX list.  There
-		is no danger if you have this option turned off (the default).
-		Problem noted by Dan Bernstein.  Also, make the DontInitGroups
-		unsafe.  I know of no specific attack against this, although
-		a denial-of-service attack is probably possible, but in theory
-		you should not be able to safely tweak anything that affects
-		the permissions that are used when mail is delivered.
-	Purgestat could go into an infinite loop if one of the host status
-		directories somehow became empty.  Problem noted by Roy
-		Mongiovi of Georgia Tech.
-	Processes got "lost" when counting children due to a race condition.
-		This caused "proc_list_probe: lost pid" messages to be logged.
-		Problem noted by several people.
-	On systems with System V SIGCLD child signal semantics (notably AIX
-		and HP-UX), mail transactions would print the message "451
-		SMTP-MAIL: lost child: No child processes".  Problem noted
-		by several people.
-	Miscellaneous compiler warnings on picky compilers (or when setting
-		gcc to high warning levels).  From Tom Moore of NCR Corp.
-	SMTP protocol errors, and most errors on MAIL FROM: lines should
-		not be persistent between runs, since they are based on the
-		message rather than the host.  Problem noted by Matt Dillon
-		of Best Internet Communications.
-	The F=7 flag was ignored on SMTP mailers.  Problem noted by Tom Moore
-		of NCR (a.k.a., AT&T Global Information Solutions).
-	Avoid the possibility of having a child daemon run to completion
-		(including closing the SMTP socket) before the parent has
-		had a chance to close the socket; this can cause the parent
-		to hang for a long time waiting for the socket to drain.
-		Patch from Don Lewis of TDK Semiconductor.
-	If the fork() failed in a queue run, the queue runners would not be
-		rescheduled (so queue runs would stop).  Patch from Don Lewis.
-	Some error conditions in ETRN could cause output without an SMTP
-		status code.  Problem noted by Don Lewis.
-	Multiple :maildrop addresses in the user database didn't work properly.
-		Patch from Roy Mongiovi of Georgia Tech.
-	Add ".db" automatically onto any user database spec that does not
-		already have it; this is for consistency with makemap, the
-		K line, and the documentation.  Inconsistency pointed out
-		by Roy Mongiovi.
-	Allow sendmail to be properly called in nohup mode.  Patch from
-		Kyle Jones of UUNET.
-	Change ETRN to ignore but still update host status files; previously
-		it would ignore them and not save the updated status, which
-		caused stale information to be maintained.  Based on a patch
-		from Christopher Davis of Kapor Enterprises Inc.  Also, have
-		ETRN ignore the MinQueueAge option.
-	Patch long term host status to recover more gracefully from an empty
-		host status file condition.  Patch from NAKAMURA Motonori
-		of Kyoto University.
-	Several patches to signal handling code to fix potential race
-		conditions from Don Lewis.
-	Make it possible to compile with -DDAEMON=0 (previously it had some
-		compile errors).  This turns DAEMON, QUEUE, and SMTP into
-		0/1 compilation flags.  Note that DAEMON is an obsolete
-		compile flag; use NETINET instead.  Solution based on a
-		patch from Bryan Costales.
-	PORTABILITY FIXES:
-		AIX4: getpwnam() and getpwuid() do a sequential scan of the
-			/etc/security/passwd file when called as root.  This
-			is very slow on some systems.  To speed it up, use the
-			(undocumented) _getpw{nam,uid}_shadow() routines.
-			Patch from Chris Thomas of UCLA/OAC Systems Group.
-		SCO 5.x: include -lprot in the Makefile.  Patch from Bill
-			Glicker of Burrelle's Information Service.
-		NEWS-OS 4.x: need a definition for MODE_T to compile.  Patch

-8.8.3/8.8.3	1996/11/17
-	SECURITY: it was possible to get a root shell by lying to sendmail
-		about argv[0] and then sending it a signal.  Problem noted
-		by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the
-		best-of-security list.
-	Log sendmail binary version number in "Warning: .cf version level
-		(%d) exceeds program functionality (%d) message" -- this
-		should make it clearer to people that they are running
-		the wrong binary.
-	Fix a problem that occurs when you open an SMTP connection and then
-		do one or more ETRN commands followed by a MAIL command; at
-		the end of the DATA phase sendmail would incorrectly report
-		"451 SMTP-MAIL: lost child: No child processes".  Problem
-		noted by Eric Bishop of Virginia Tech.
-	When doing text-based host canonification (typically /etc/hosts
-		lookup), a null host name would match any /etc/hosts entry
-		with space at the end of the line.  Problem noted by Steve
-		Hubert of the University of Washington, Seattle.
-	7 to 8 bit BASE64 MIME conversions could duplicate bits of text.
-		Problem reported by Tom Smith of Digital Equipment Corp.
-	Increase the size of the DNS answer buffer -- the standard UDP packet
-		size PACKETSZ (512) is not sufficient for some nameserver
-		answers containing very many resource records.  The resolver
-		may also switch to TCP and retry if it detects UDP packet
-		overflow.  Also, allow for the fact that the resolver
-		routines res_query and res_search return the size of the
-		*un*truncated answer in case the supplied answer buffer it
-		not big enough to accommodate the entire answer.  Patch from
-		Eric Wassenaar.
-	Improvements to MaxDaemonChildren code.  If you think you have too
-		many children, probe the ones you have to verify that they
-		are still around.  Suggested by Jared Mauch of CICnet, Inc.
-		Also, do this probe before growing the vector of children
-		pids; this previously caused the vector to grow indefinitely
-		due to a race condition.  Problem reported by Kyle Jones of
-		UUNET.
-	On some architectures, <db.h> (from the Berkeley DB library) defines
-		O_EXLOCK to zero; this fools the map compilation code into
-		thinking that it can avoid race conditions by locking on open.
-		Change it to check for O_EXLOCK non-zero.  Problem noted by
-		Leif Erlingsson of Data Lege.
-	Always call res_init() on startup (if compiled in, of course) to
-		allow the sendmail.cf file to tweak resolver flags; without
-		it, flag tweaks in ResolverOptions are ignored.  Patch from
-		Andrew Sun of Merrill Lynch.
-	Improvements to host status printing code.  Suggested by Steve Hubert
-		of the University of Washington, Seattle.
-	Change MinQueueAge option processing to do the check for the job age
-		when reading the queue file, rather than at the end; this
-		avoids parsing the addresses, which can do DNS lookups.
-		Problem noted by John Beck of InReference, Inc.
-	When MIME was being 7->8 bit decoded, "From " lines weren't being
-		properly escaped.  Problem noted by Peter Nilsson of the
-		University of Linkoping.
-	In some cases, sendmail would retain root permissions during queue
-		runs even if RunAsUser was set.  Problem noted by Mark
-		Thomas of Mark G. Thomas Consulting.
-	If the F=l flag was set on an SMTP mailer to indicate that it is
-		actually local delivery, and NOTIFY=SUCCESS is specified in
-		the envelope, and the receiving SMTP server speaks DSN, then
-		the DSN would be both generated locally and propagated to the
-		other end.
-	The U= mailer field didn't correctly extract the group id if the
-		user id was numeric.  Problem noted by Kenneth Herron of
-		MCI Telecommunications Communications.
-	If a message exceeded the fixed maximum size on input, the body of
-		the message was included in the bounce.  Note that this did
-		not occur if it exceeded the maximum _output_ size.  Problem
-		reported by Kyle Jones of UUNET.
-	PORTABILITY FIXES:
-		AIX4: 4.1 doesn't have a working setreuid(2); change the
-			AIX4 defines to use seteuid(2) instead, which
-			works on 4.1 as well as 4.2.  Problem noted by
-			Håkan Lindholm of interAF, Sweden.
-		AIX4: use tzname[] vector to determine time zone name.
-			Patch from NAKAMURA Motonori of Kyoto University.
-		MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support.
-			Contributed by Paul DuBois <dubois@primate.wisc.edu>.
-		Solaris: kstat(3k) support for retrieving the load average.
-			This adds the LA_KSTAT definition for LA_TYPE.
-			The outline of the implementation was contributed
-			by Michael Tokarev of Telecom Service, JSC, Moscow.
-		HP-UX 10.0 gripes about the (perfectly legal!) forward
-			declaration of struct rusage at the top of conf.h;
-			change it to only be included if you are using gcc,
-			which is apparently the only compiler that requires
-			it in the first place.  Problem noted by Jeff
-			Earickson of Colby College.
-		IRIX: don't default to using gcc.  IRIX is a civilized
-			operating system that comes with a decent compiler
-			by default.  Problem noted by Barry Bouwsma and
-			Kari Hurtta.
-	CONFIG: specify F=9 as default in FEATURE(local_procmail) for
-		consistency with other local mailers.  Inconsistency
-		pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>.
-	CONFIG: if the "limited best mx" feature is used (to reduce DNS
-		overhead) as part of the bestmx_is_local feature, the
-		domain part was dropped from the name.  Patch from Steve
-		Hubert of the University of Washington, Seattle.
-	CONFIG: catch addresses of the form "user@.dom.ain"; these could
-		end up being translated to the null host name, which would
-		return any entry in /etc/hosts that had a space at the end
-		of the line.  Problem noted by Steve Hubert of the
-		University of Washington, Seattle.
-	CONFIG: add OSTYPE(aix4).  From Michael Sofka of Rensselaer

-8.8.2/8.8.2	1996/10/18
-	SECURITY: fix a botch in the 7-bit MIME patch; the previous patch
-		changed the code but didn't fix the problem.
-	PORTABILITY FIXES:
-		Solaris: Don't use the system getusershell(3); it can
-			apparently corrupt the heap in some circumstances.
-			Problem found by Ken Pizzini of Spry, Inc.
-	OP.ME: document several mailer flags that were accidentally omitted
-		from this document.  These flags were F=d, F=j, F=R, and F=9.
-	CONFIG: no changes.
-
-8.8.1/8.8.1	1996/10/17
-	SECURITY: unset all environment variables that the resolver will
-		examine during queue runs and daemon mode.  Problem noted
-		by Dan Bernstein of the University of Illinois at Chicago.
-	SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain
-		message could overflow a buffer if it was converted back
-		to 8 bits.  This caused core dumps and has the potential
-		for a remote attack.  Problem first noted by Gregory Shapiro
-		of WPI.
-	Avoid duplicate deliveries of error messages on systems that don't
-		have flock(2) support.  Patch from Motonori Nakamura of
-		Kyoto University.
-	Ignore null FallBackMX (V) options.  If this option is null (as
-		opposed to undefined) it can cause "null signature" syserrs
-		on illegal host names.
-	If a Base64 encoded text/plain message has no trailing newline in
-		the encoded text, conversion back to 8 bits will drop the
-		final line.  Problem noted by Pierre David.
-	If running with a RunAsUser, sendmail would give bogus "cannot
-		setuid" (or seteuid, or setreuid) messages on some systems.
-		Problem pointed out by Jordan Mendelson of Web Services, Inc.
-	Always print error messages in -bv mode -- previously, -bv would
-		be absolutely silent on errors if the error mode was sent
-		to (say) mail-back.  Problem noted by Kyle Jones of UUNET.
-	If -qI/R/S is set (or the ETRN command is used), ignore all long
-		term host status.  This is necessary because it is common
-		to do this when you know a host has just come back up.
-	Disallow duplicate HELO/EHLO commands as required by RFC 1651 section
-		4.2.  Excessive permissiveness noted by Lee Flight of the
-		University of Leicester.
-	If a service (such as NIS) is specified as the last entry in the
-		service switch, but that service is not compiled in, sendmail
-		would return a temporary failure when an entry was not found
-		in the map.  This caused the message to be queued instead of
-		bouncing immediately.  Problem noted by Harry Edmon of the
-		University of Washington.
-	PORTABILITY FIXES:
-		Solaris 2.3 had compilation problems in conf.c.  Several
-			people pointed this out.
-		NetBSD from Charles Hannum of MIT.
-		AIX4 improvements based on info from Steve Bauer of South
-			Dakota School of Mines & Technology.
-	CONFIG: ``error:code message'' syntax was broken in virtusertable.
-		Patch from Gil Kloepfer Jr.
-	CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set
-		using MASQUERADE_DOMAIN) were not masqueraded unless they
-		were also in $=w.  Problem noted by Zoltan Basti of
-		Softec.
-	MAIL.LOCAL: patches to compile and link cleanly on AIX.  Based
-		on a patch from Eric Hagberg of Morgan Stanley.
-	MAIL.LOCAL: patches to compile on NEXTSTEP.  From Patrick Nolan
-		of Stanford via Robert La Ferla.
-
-8.8.0/8.8.0	1996/09/26
-	Under some circumstances, Bcc: headers would not be properly
-		deleted.  Pointed out by Jonathan Kamens of OpenVision.
-	Log a warning if the sendmail daemon is invoked without a full
-		pathname, which prevents "kill -1" from working.  I was
-		urged to put this in by Andrey A. Chernov of DEMOS (Russia).
-	Fix small buffer overflow.  Since the data in this buffer was not
-		read externally, there was no security problem (and in fact
-		probably wouldn't really overflow on most compilers).  Pointed
-		out by KIZU takashi of Osaka University.
-	Fix problem causing domain literals such as [1.2.3.4] to be ignored
-		if a FallbackMXHost was specified in the configuration file
-		-- all mail would be sent to the fallback even if the original
-		host was accessible.  Pointed out by Munenari Hirayama of
-		NSC (Japan).
-	A message that didn't terminate with a newline would (sometimes) not
-		have the trailing "." added properly in the SMTP dialogue,
-		causing SMTP to hang.  Patch from Per Hedeland of Ericsson.
-	The DaemonPortOptions suboption to bind to a particular address was
-		incorrect and nonfunctional due to a misunderstanding of the
-		semantics of binding on a passive socket.  Patch from
-		NIIBE Yutaka of Mitsubishi Research Institute.
-	Increase the number of MX hosts for a single name to 100 to better
-		handle the truly huge service providers such as AOL, which
-		has 13 at the moment (and climbing).  In order to avoid
-		trashing memory, the buffer for all names has only been
-		slightly increased in size, to 12.8K from 10.2K -- this means
-		that if a single name had 100 MX records, the average size
-		of those records could not exceed 128 bytes.  Requested by
-		Brad Knowles of America On Line.
-	Restore use of IDENT returns where the OSTYPE field equals "OTHER".
-		Urged by Dan Bernstein of U.C. Berkeley.
-	Print q_statdate and q_specificity in address structure debugging
-		printout.
-	Expand MCI structure flag bits for debugging output.
-	Support IPv6-style domain literals, which can have colons between
-		square braces.
-	Log open file descriptors for the "cannot dup" messages in deliver();
-		this is an attempt to track down a bug that one person seems
-		to be having (it may be a Solaris bug!).
-	DSN NOTIFY parameters were not properly propagated across queue runs;
-		this caused the NOTIFY info to sometimes be lost.  Problem
-		pointed out by Claus Assmann of the
-		Christian-Albrechts-University of Kiel.
-	The statistics gathered in the sendmail.st file were too high; in
-		some cases failures (e.g., user unknown or temporary failure)
-		would count as a delivery as far as the statistics were
-		concerned.  Problem noted by Tom Moore of AT&T GIS.
-	Systems that don't have flock() would not send split envelopes in
-		the initial run.  Problem pointed out by Leonard Zubkoff of
-		Dandelion Digital.
-	Move buffer overflow checking -- these primarily involve distrusting
-		results that may come from NIS and DNS.
-	4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't
-		include <paths.h> and hence had the wrong pathnames for a few
-		things like /var/tmp.  Reported by Matthew Green.
-	Conditions were reversed for the Priority: header, resulting in all
-		values being interpreted as non-urgent except for non-urgent,
-		which was interpreted as normal.  Patch from Bryan Costales.
-	The -o (optional) flag was being ignored on hash and btree maps
-		since 8.7.2.  Fix from Bryan Costales.
-	Content-Types listed in class "q" will always be encoded as
-		Quoted-Printable (or more accurately, will never be encoded
-		as base64).  The class can have primary types (e.g., "text")
-		or full types (e.g., "text/plain").  Based on a suggestion by
-		Marius Olafsson of the University of Iceland.
-	Define ${envid} to be the original envelope id (from the ESMTP DSN
-		dialogue) so it can be passed to programs in mailers.
-	Define ${bodytype} to be the body type (from the -B flag or the
-		BODY= ESMTP parameter) so it can be passed to programs in
-		mailers.
-	Cause the VRFY command to return 252 instead of 250 unless the F=q
-		flag is set in the mailer descriptor.  Suggested by John
-		Myers of CMU.
-	Implement ESMTP ETRN command to flush the queue for a specific host.
-		The command takes a host name; data for that host is
-		immediately (and asynchronously) flushed.  Because this shares
-		the -qR implementation, other hosts may be attempted, but
-		there should be no security implications.  Implementation
-		from John Beck of InReference, Inc.  See RFC 1985 for details.
-	Add three new command line flags to pass in DSN parameters: -V envid
-		(equivalent to ENVID=envid on the MAIL command), -R ret
-		(equivalent to RET=ret on the MAIL command), and -Nnotify
-		(equivalent to NOTIFY=notify on the RCPT command).  Note
-		that the -N flag applies to all recipients; there is no way
-		to specify per-address notifications on the command line,
-		nor is there an equivalent for the ORCPT= per-address
-		parameter.
-	Restore LogLevel option to be safe (it can only be increased);
-		apparently I went into paranoid mode between 8.6 and 8.7
-		and made it unsafe.  Pointed out by Dabe Murphy of the
-		University of Maryland.
-	New logging on log level 15:  all SMTP traffic.  Patches from
-		Andrew Gross of San Diego Supercomputer Center.
-	NetInfo property value searching code wasn't stopping when it found
-		a match.  This was causing the wrong values to be found (and
-		had a memory leak).  Found by Bastian Schleuter of TU-Berlin.
-	Add new F=0 (zero) mailer flag to turn off MX lookups.  It was pointed
-		out by Bill Wisner of Electronics for Imaging that you can't
-		use the bracket address form for the MAIL_HUB macro, since
-		that causes the brackets to remain in the envelope recipient
-		address used for delivery.  The simple fix (stripping off the
-		brackets in the config file) breaks the use of IP literal
-		addresses.  This flag will solve that problem.
-	Add MustQuoteChars option.  This is a list of characters that must
-		be quoted if they are found in the phrase part of an address
-		(that is, the full name part).  The characters @,;:\()[] are
-		always in this list and cannot be removed.  The default is
-		this list plus . and ' to match RFC 822.
-	Add AllowBogusHELO option; if set, sendmail will allow HELO commands
-		that do not include a host name for back compatibility with
-		some stupid SMTP clients.  Setting this violates RFC 1123
-		section 5.2.5.
-	Add MaxDaemonChildren option; if this is set, sendmail will start
-		rejecting connections if it has more than this many
-		outstanding children accepting mail.  Note that you may
-		see more processes than this because of outgoing mail; this
-		is for incoming connections only.
-	Add ConnectionRateThrottle option.  If set to a positive value, the
-		number of incoming SMTP connections that will be permitted
-		in a single second is limited to this number.  Connections are
-		not refused during this time, just deferred.  The intent is to
-		flatten out demand so that load average limiting can kick in.
-		It is less radical than MaxDaemonChildren, which will stop
-		accepting connections even if all the connections are idle
-		(e.g., due to connection caching).
-	Add Timeout.hoststatus option.  This interval (defaulting to 30m)
-		specifies how long cached information about the state of a
-		host will be kept before they are considered stale and the
-		host is retried.  If you are using persistent host status
-		(i.e., the HostStatusDirectory option is set) this will apply
-		between runs; otherwise, it applies only within a single queue
-		run and hence is useful only for hosts that have large queues
-		that take a very long time to run.
-	Add SingleLineFromHeader option.  If set, From: headers are coerced
-		into being a single line even if they had newlines in them
-		when read.  This is to get around a botch in Lotus Notes.
-	Text class maps were totally broken -- if you ever retrieved the last
-		item in a table it would be truncated.  Problem noted by
-		Gregory Neil Shapiro of WPI.
-	Extend the lines printed by the mailq command (== the -bp flag) when
-		-v is given to 120 characters; this allows more information
-		to be displayed.  Suggested by Gregory Neil Shapiro of WPI.
-	Allow macro definitions (`D' lines) with unquoted commas; previously
-		this was treated as end-of-input.  Problem noted by Bryan
-		Costales.
-	The RET= envelope parameter (used for DSNs) wasn't properly written
-		to the queue file.  Fix from John Hughes of Atlantic
-		Technologies, Inc.
-	Close /var/tmp/dead.letter after a successful write -- otherwise
-		if this happens in a queue run it can cause nasty delays.
-		Problem noted by Mark Horton of AT&T.
-	If userdb entries pointed to userdb entries, and there were multiple
-		values for a given key, the database cursor would get
-		trashed by the recursive call.  Problem noted by Roy Mongiovi
-		of Georgia Tech.  Fixed by reading all the values and creating
-		a comma-separated list; thus, the -v output will be somewhat
-		different for this case.
-	Fix buffer allocation problem with Hesiod-based userdb maps when
-		HES_GETMAILHOST is defined.  Based on a patch by Betty Lee
-		of Stanford University.
-	When envelopes were split due to aliases with owner- aliases, and
-		there was some error on one of the lists, more than one of
-		the owners would get the message.  Problem pointed out by
-		Roy Mongiovi of Georgia Tech.
-	Detect excessive recursion in macro expansions, e.g., $X defined
-		in terms of $Y which is defined in terms of $X.  Problem
-		noted by Bryan Costales; patch from Eric Wassenaar.
-	When using F=U to get "ugly UUCP" From_ lines, a buffer could in
-		some cases get trashed causing bogus From_ lines.  Fix from
-		Kyle Jones of UUNET.
-	When doing load average initialization, if the nlist call for avenrun
-		failed, the second and subsequent lookups wouldn't notice
-		that fact causing bogus load averages to be returned.  Noted
-		by Casper Dik of Sun Holland.
-	Fix problem with incompatibility with some versions of inet_aton that
-		have changed the return value to unsigned, so a check for an
-		error return of -1 doesn't work.  Use INADDR_NONE instead.
-		This could cause mail to addresses such as [foo.com] to bounce
-		or get dropped.  Problem noted by Christophe Wolfhugel of the
-		Pasteur Institute.
-	DSNs were inconsistent if a failure occurred during the DATA phase
-		rather than the RCPT phase: the Action: would be correct, but
-		the detailed status information would be wrong.  Problem noted
-		by Bob Snyder of General Electric Company.
-	Add -U command line flag and the XUSR ESMTP extension, both indicating
-		that this is the initial MUA->MTA submission.  The flag current
-		does nothing, but in future releases (when MUAs start using
-		these flags) it will probably turn on things like DNS
-		canonification.
-	Default end-of-line string (E= specification on mailer [M] lines)
-		to \r\n on SMTP mailers.  Default remains \n on non-SMTP
-		mailers.
-	Change the internal definition for the *file* and *include* mailers
-		to have $u in the argument vectors so that they aren't
-		misinterpreted as SMTP mailers and thus use \r\n line
-		termination.  This will affect anyone who has redefined
-		either of these in their configuration file.
-	Don't assume that IDENT servers close the connection after a query;
-		responses can be newline terminated.  From Terry Kennedy of
-		St. Peter's College.
-	Avoid core dumps on erroneous configuration files that have
-		$#mailer with nothing following.  From Bryan Costales.
-	Avoid null pointer dereference with high debug values in unlockqueue.
-		Fix from Randy Martin of Clemson University.
-	Fix possible buffer overrun when expanding very large macros.  Fix
-		from Kyle Jones of UUNET.
-	After 25 EXPN or VRFY commands, start pausing for a second before
-		processing each one.  This avoids a certain form of denial
-		of service attack.  Potential attack pointed out by Bryan
-		Costales.
-	Allow new named (not numbered!) config file rules to do validity
-		checking on SMTP arguments: check_mail for MAIL commands and
-		check_rcpt for RCPT commands.  These rulesets can do anything
-		they want; their result is ignored unless they resolve to the
-		$#error mailer, in which case the indicated message is printed
-		and the command is rejected.  Similarly, the check_compat
-		ruleset is called before delivery with "from_addr $| to_addr"
-		(the $| is a meta-symbol used to separate the two addresses);
-		it can give a "this sender can't send to this recipient"
-		notification.  Note that this patch allows $| to stand alone
-		in rulesets.
-	Define new macros ${client_name}, ${client_addr}, and ${client_port}
-		that have the name, IP address, and port number (respectively)
-		of the SMTP client (that is, the entity at the other end of
-		the connection.  These can be used in (e.g.) check_rcpt to
-		verify that someone isn't trying to relay mail through your
-		host inappropriately.  Be sure to use the deferred evaluation
-		form, for example $&{client_name}, to avoid having these bound
-		when sendmail reads the configuration file.
-	Add new config file rule check_relay to check the incoming connection
-		information.  Like check_compat, it is passed the host name
-		and host address separated by $| and can reject connections
-		on that basis.
-	Allow IDA-style recursive function calls.  Code contributed by Mark
-		Lovell and Paul Vixie.
-	Eliminate the "No ! in UUCP From address!" message" -- instead, create
-		a virtual UUCP address using either a domain address or the $k
-		macro.  Based on code contributed by Mark Lovell and Paul
-		Vixie.
-	Add Stanford LDAP map.  Requires special libraries that are not
-		included with sendmail.  Contributed by Booker C. Bense
-		<bbense@networking.stanford.edu>; contact him for support.
-		See also the src/READ_ME file.
-	Allow -dANSI to turn on ANSI escape sequences in debug output; this
-		puts metasymbols (e.g., $+) in reverse video.  Really useful
-		only for debugging deep bits of code where it is important to
-		distinguish between the single-character metasymbol $+ and the
-		two characters $, +.
-	Changed ruleset 89 (executed in dumpstate()) to a named ruleset,
-		debug_dumpstate.
-	Add new UnsafeGroupWrites option; if set, .forward and :include:
-		files that are group writable are considered "unsafe" -- that
-		is, programs and files referenced from such files are not
-		valid recipients.
-	Delete bogosity test for FallBackMX host; this prevented it to be a
-		name that was not in DNS or was a domain-literal.  Problem
-		noted by Tom May.
-	Change the introduction to error messages to more clearly delineate
-		permanent from temporary failures; if both existed in a
-		single message it could be confusing.  Suggested by John
-		Beck of InReference, Inc.
-	The IngoreDot (i) option didn't work for lines that were terminated
-		with CRLF.  Problem noted by Ted Stockwell of Secure
-		Computing Corporation.
-	Add a heuristic to improve the handling of unbalanced `<' signs in
-		message headers.  Problem reported by Matt Dillon of Best
-		Internet Communications.
-	Check for bogus characters in the 0200-0237 range; since these are
-		used internally, very strange errors can occur if those
-		characters appear in headers.  Problem noted by Anders Gertz
-		of Lysator.
-	Implement 7 -> 8 bit MIME conversions.  This only takes place if the
-		recipient mailer has the F=9 flag set, and only works on
-		text/plain body types.  Code contributed by Marius Olafsson
-		of the University of Iceland.
-	Special case "postmaster" name so that it is always treated as lower
-		case in alias files regardless of configuration settings;
-		this prevents some potential problems where "Postmaster" or
-		"POSTMASTER" might not match "postmaster".  In most cases
-		this change is a no-op.
-	The -o map flag was ignored for text maps.  Problem noted by Bryan
-		Costales.
-	The -a map flag was ignored for dequote maps.  Problem noted by
-		Bryan Costales.
-	Fix core dump when a lookup of a class "prog" map returns no
-		response.  Patch from Bryan Costales.
-	Log instances where sendmail is deferring or rejecting connections
-		on LogLevel 14.  Suggested by Kyle Jones of UUNET.
-	Include port number in process title for network daemons.  Suggested
-		by Kyle Jones of UUNET.
-	Send ``double bounces'' (errors that occur when sending an error
-		message) to the address indicated in the DoubleBounceAddress
-		option (default: postmaster).  Previously they were always
-		sent to postmaster.  Suggested by Kyle Jones of UUNET.
-	Add new mode, -bD, that acts like -bd in all respects except that
-		it runs in foreground.  This is useful for using with a
-		wrapper that "watches" system services.  Suggested by Kyle
-		Jones of UUNET.
-	Fix botch in spacing around (parenthesized) comments in addresses
-		when the comment comes before the address.  Patch from
-		Motonori Nakamura of Kyoto University.
-	Use the prefix "Postmaster notify" on the Subject: lines of messages
-		that are being bounced to postmaster, rather than "Returned
-		mail".  This permits the person who is postmaster more
-		easily determine what messages are to their role as
-		postmaster versus bounces to mail they actually sent.  Based
-		on a suggestion by Motonori Nakamura.
-	Add new value "time" for QueueSortOrder option; this causes the queue
-		to be sorted strictly by the time of submission.  Note that
-		this can cause very bad behavior over slow lines (because
-		large jobs will tend to delay small jobs) and on nodes with
-		heavy traffic (because old things in the queue for hosts that
-		are down delay processing of new jobs).  Also, this does not
-		guarantee that jobs will be delivered in submission order
-		unless you also set DeliveryMode=queue.  In general, it should
-		probably only be used on the command line, and only in
-		conjunction with -qRhost.domain.  In fact, there are very few
-		cases where it should be used at all.  Based on an
-		implementation by Motonori Nakamura.
-	If a map lookup in ruleset 5 returns tempfail, queue the message in
-		the same manner as other rulesets.  Previously a temporary
-		failure in ruleset 5 was ignored.  Patch from Booker Bense
-		of Stanford University.
-	Don't proceed to the next MX host if an SMTP MAIL command returns a
-		5yz (permanent failure) code.  The next MX host will still be
-		tried if the connection cannot be opened in the first place
-		or if the MAIL command returns a 4yz (temporary failure) code.
-		(It's hard to know what to do here, since neither RFC 974 nor
-		RFC 1123 specify when to proceed to the next MX host.)
-		Suggested by Jonathan Kamens of OpenVision, Inc.
-	Add new "-t" flag for map definitions (the "K" line in the .cf file).
-		This causes map lookups that get a temporary failure (e.g.,
-		name server failure) to _not_ defer the delivery of the
-		message.  This should only be used if your configuration file
-		is prepared to do something sensible in this case.  Based on
-		an idea by Gregory Shapiro of WPI.
-	Fix problem finding network interface addresses.  Patch from
-		Motonori Nakamura.
-	Don't reject qf entries that are not owned by your effective uid if
-		you are not running set-user-ID; this makes management of
-		certain kinds of firewall setups difficult.  Patch
-		suggested by Eamonn Coleman of Qualcomm.
-	Add persistent host status.  This keeps the information normally
-		maintained within a single queue run in disk files that are
-		shared between sendmail instances.  The HostStatusDirectory
-		is the directory in which the information is maintained.  If
-		not set, persistent host status is turned off.  If not a full
-		pathname, it is relative to the queue directory.  A common
-		value is ".hoststat".
-		There are also two new operation modes:
-		  * -bh prints the status of hosts that have had recent
-		    connections.
-		  * -bH purges the host statuses.  No attempt is made to save
-		    recent status information.
-		This feature was originally written by Paul Vixie of Vixie
-		Enterprises for KJS and adapted for V8 by Mark Lovell of
-		Bigrock Consulting.  Paul's funding of Mark and Mark's patience
-		with my insistence that things fit cleanly into the V8
-		framework is gratefully appreciated.
-	New SingleThreadDelivery option (requires HostStatusDirectory to
-		operate).  Avoids letting two sendmails on the local machine
-		open connections to the same remote host at the same time.
-		This reduces load on the other machine, but can cause mail to
-		be delayed (for example, if one sendmail is delivering a huge
-		message, other sendmails won't be able to send even small
-		messages).  Also, it requires another file descriptor (for the
-		lock file) per connection, so you may have to reduce
-		ConnectionCacheSize to avoid running out of per-process
-		file descriptors.  Based on the persistent host status code
-		contributed by Paul Vixie and Mark Lovell.
-	Allow sending to non-simple files (e.g., /dev/null) even if the
-		SafeFileEnvironment option is set.  Problem noted by Bryan
-		Costales.
-	The -qR flag mistakenly matched flags in the "R" line of the queue
-		file.  Problem noted by Bryan Costales.
-	If a job was aborted using the interrupt signal (e.g., control-C from
-		the keyboard), on some occasions an empty df file would be
-		left around; these would collect in the queue directory.
-		Problem noted by Bryan Costales.
-	Change the makesendmail script to enhance the search for Makefiles
-		based on release number.  For example, on SunOS 5.5.1, it will
-		search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then
-		Makefile.SunOS.5.x (in addition to the other rules, e.g.,
-		adding $arch).  Problem noted by Jason Mastaler of Atlanta
-		Webmasters.
-	When creating maps using "newaliases", always map the keys to lower
-		case when creating the map unless the -f flag is specified on
-		the map itself.  Previously this was done based on the F=u
-		flag in the local mailer, which meant you could create aliases
-		that you could never access.  Problem noted by Bob Wu of DEC.
-	When a job was read from the queue, the bits causing notification on
-		failure or delay were always set.  This caused those
-		notifications to be sent even if NOTIFY=NEVER had been
-		specified.  Problem noted by Steve Hubert of the University
-		of Washington, Seattle.
-	Add new configurable routine validate_connection (in conf.c).  This
-		lets you decide if you are willing to accept traffic from
-		this host.  If it returns FALSE, all SMTP commands will return
-		"550 Access denied".  -DTCPWRAPPERS will include support for
-		TCP wrappers; you will need to add -lwrap to the link line.
-		(See src/READ_ME for details.)
-	Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster
-		bounces.  Some people seemed to think that this could be
-		confusing (even though it is true).  Suggested by Motonori
-		Nakamura.
-	Add new RunAsUser option; this causes sendmail to do a setuid to that
-		user early in processing to avoid potential security problems.
-		However, this means that all .forward and :include: files must
-		be readable by that user, and all files to be written must be
-		writable by that user and all programs will be executed by that
-		user.  It is also incompatible with the SafeFileEnvironment
-		option.  In other words, it may not actually add much to
-		security.  However, it should be useful on firewalls and other
-		places where users don't have accounts and the aliases file is
-		well constrained.
-	Add Timeout.iconnect.  This is like Timeout.connect except it is used
-		only on the first attempt to delivery to an address.  It could
-		be set to be lower than Timeout.connect on the principle that
-		the mail should go through quickly to responsive hosts; less
-		responsive hosts get to wait for the next queue run.
-	Fix a problem on Solaris that occasionally causes programs
-		(such as vacation) to hang with their standard input connected
-		to a UDP port.  It also created some signal handling problems.
-		The problems turned out to be an interaction between vfork(2)
-		and some of the libraries, particularly NIS/NIS+.  I am
-		indebted to Tor Egge <tegge@idt.ntnu.no> for this fix.
-	Change user class map to do the same matching that actual delivery
-		will do instead of just a /etc/passwd lookup.  This adds
-		fuzzy matching to the user map.  Patch from Dan Oscarsson.
-	The Timeout.* options are not safe -- they can be used to create a
-		denial-of-service attack.  Problem noted by Christophe
-		Wolfhugel.
-	Don't send PostmasterCopy messages in the event of a "delayed"
-		notification.  Suggested by Barry Bouwsma.
-	Don't advertise "VERB" ESMTP extension if the "noexpn" privacy
-		option is set, since this disables VERB mode.  Suggested
-		by John Hawkinson of MIT.
-	Complain if the QueueDirectory (Q) option is not set.  Problem noted
-		by Motonori Nakamura of Kyoto University.
-	Only queue messages on transient .forward open failures if there
-		were no successful opens.  The previous behavior caused it
-		to queue even if a "fall back" .forward was found.  Problem
-		noted by Ann-Kian Yeo of the Dept. of Information Systems
-		and Computer Science (DISCS), NUS, Singapore.
-	Don't do 8->7 bit conversions when bouncing a MIME message that
-		is bouncing because of a MIME error during 8->7 bit conversion;
-		the encapsulated message will bounce again, causing a loop.
-		Problem noted by Steve Hubert of the University of Washington.
-	Create xf (transcript) files using the TempFileMode option value
-		instead of 0644.  Suggested by Ann-Kian Yeo of the
-		National University of Singapore.
-	Print errors if setgid/setuid/etc. fail during delivery.  This helps
-		detect cases where DefaultUid is set to something that the
-		system can't cope with.
-	PORTABILITY FIXES:

-	CONFIG: add generic-nextstep3.3.mc file.  Contributed by
-		Robert La Ferla of Hot Software.
-	CONFIG: allow mailertables to resolve to ``error:code message''
-		(where "code" is an exit status) on domains (previously
-		worked only on hosts).  Patch from Cor Bosman of Xs4all
-		Foundation.
-	CONFIG: hooks for IPv6-style domain literals.
-	CONFIG: predefine ALIAS_FILE and change the prototype file so that
-		if it is undefined the AliasFile option is never set; this
-		should be transparent for most everyone.  Suggested by John
-		Myers of CMU.
-	CONFIG: add FEATURE(limited_masquerade).  Without this feature, any
-		domain listed in $=w is masqueraded.  With it, only those
-		domains listed in a MASQUERADE_DOMAIN macro are masqueraded.
-	CONFIG: add FEATURE(masquerade_entire_domain).  This causes
-		masquerading specified by MASQUERADE_DOMAIN to apply to all
-		hosts under those domains as well as the domain headers
-		themselves.  For example, if a configuration had
-		MASQUERADE_DOMAIN(foo.com), then without this feature only
-		foo.com would be masqueraded; with it, *.foo.com would be
-		masqueraded as well.  Based on an implementation by Richard
-		(Pug) Bainter of U. Texas.
-	CONFIG: add FEATURE(genericstable) to do a more general rewriting of
-		outgoing addresses.  Defaults to ``hash -o /etc/genericstable''.
-		Keys are user names; values are outgoing mail addresses.  Yes,
-		this does overlap with the user database, and figuring out
-		just when to use which one may be tricky.  Based on code
-		contributed by Richard (Pug) Bainter of U. Texas with updates
-		from Per Hedeland of Ericsson.
-	CONFIG: add FEATURE(virtusertable) to do generalized rewriting of
-		incoming addresses.  Defaults to ``hash -o /etc/virtusertable''.
-		Keys are either fully qualified addresses or just the host
-		part (with the @ sign).  For example, a table containing:
-			info@foo.com	foo-info
-			info@bar.com	bar-info
-			@baz.org	jane@elsewhere.net
-		would send all mail destined for info@foo.com to foo-info
-		(which is presumably an alias), mail addressed to info@bar.com
-		to bar-info, and anything addressed to anyone at baz.org will
-		be sent to jane@elsewhere.net.  The names foo.com, bar.com,
-		and baz.org must all be in $=w.  Based on discussions with
-		a great many people.
-	CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS.
-		Suggested by Richard Bainter.
-	CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the
-		"fax" mailer.
-	CONFIG: allow mailertable entries to resolve to local:user; this
-		passes the original user@host in to procmail-style local
-		mailers as the "detail" information to allow them to do
-		additional clever processing.  From Joe Pruett of
-		Teleport Corporation.  Delivery to the original user can
-		be done by specifying "local:" (with nothing after the colon).
-	CONFIG: allow any context that takes "mailer:domain" to also take
-		"mailer:user@domain" to force mailing to the given user;
-		"local:user" can also be used to do local delivery.  This
-		applies on *_RELAY and in the mailertable entries.  Based
-		on a suggestion by Ribert Kiessling of Easynet.
-	CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that
-		limits the possible domains; this reduces the number of DNS
-		lookups required to support this feature.  For example,
-		FEATURE(bestmx_is_local, my.site.com) limits the lookups
-		to domains under my.site.com.  Code contributed by Anthony
-		Thyssen <anthony@cit.gu.edu.au>.
-	CONFIG: LOCAL_RULESETS introduces any locally defined rulesets,
-		such as the check_rcpt ruleset.  Suggested by Gregory Shapiro
-		of WPI.
-	CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the
-		event you have to define local mailers.  Suggested by
-		Gregory Shapiro of WPI.
-	CONFIG: fix cases where a three- (or more-) stage route-addr could
-		be misinterpreted as a list:...; syntax.  Based on a patch by
-		Vlado Potisk <Vlado_Potisk@tempest.sk>.
-	CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is
-		remotely connected.  The address host!user was being
-		converted to host!user@thishost instead of host!user@uurelay.
-		Problem noted by William Gianopoulos of Raytheon Company.
-	CONFIG: add confTO_ICONNECT to set Timeout.iconnect.
-	CONFIG: change FEATURE(redirect) message from "User not local" to
-		"User has moved"; the former wording was confusing if the
-		new address is still on the local host.  Based on a suggestion
-		by Andreas Luik.
-	CONFIG: add support in FEATURE(nullclient) for $=E (exposed users).
-		However, the class is not pre-initialized to contain root.
-		Suggested by Gregory Neil Shapiro.
-	CONTRIB: Remove XLA code at the request of the author, Christophe
-		Wolfhugel.
-	CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm.
-	MAIL.LOCAL: make it possible to compile mail.local on Solaris.  Note
-		well: this produces a slightly different mailbox format (no
-		Content-Length: headers), file ownerships and modes are
-		different (not owned by group mail; mode 600 instead of 660),
-		and the local mailer flags will have to be tweaked (make them
-		match bsd4.4) in order to use this mailer.  Patches from Paul
-		Hammann of the Missouri Research and Education Network.
-	MAIL.LOCAL: in some cases it could return EX_OK even though there
-		was a delivery error, such as if the ownership on the file
-		was wrong or the mode changed between the initial stat and
-		the open.  Problem reported by William Colburn of the New
-		Mexico Institute of Mining and Technology.
-	MAILSTATS: handle zero length files more reliably.  Patch from Bryan
-		Costales.
-	MAILSTATS: add man page contributed by Keith Bostic of BSDI.
-	MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't
-		honored.  Fix from Michael Scott Shappe.
-	PRALIASES: add man page contributed by Keith Bostic of BSDI.

-8.7.6/8.7.3	1996/09/17
-	SECURITY: It is possible to force getpwuid to fail when writing the
-		queue file, causing sendmail to fall back to running programs
-		as the default user.  This is not exploitable from off-site.
-		Workarounds include using a unique user for the DefaultUser
-		(old u & g options) and using smrsh as the local shell.
-	SECURITY: fix some buffer overruns; in at least one case this allows
-		a local user to get root.  This is not known to be exploitable
-		from off-site.  The workaround is to disable chfn(1) commands.
-
-8.7.5/8.7.3	1996/03/04
-	Fix glitch in 8.7.4 when putting certain internal lines; this can
-		in some case cause connections to hang or messages to have
-		extra spaces in odd places.  Patch from Eric Wassenaar;
-		reports from Eric Hall of Chiron Corporation, Stephen
-		Hansen of Stanford University, Dean Gaudet of HotWired,
-		and others.
-
-8.7.4/8.7.3	1996/02/18
-	SECURITY: In some cases it was still possible for an attacker to
-		insert newlines into a queue file, thus allowing access to
-		any user (except root).
-	CONFIG: no changes -- it is not a bug that the configuration
-		version number is unchanged.
-
-8.7.3/8.7.3	1995/12/03
-	Fix botch in name server timeout in RCPT code; this problem caused
-		two responses in SMTP, which breaks things horribly.  Fix
-		from Gregory Neil Shapiro of WPI.
-	Verify that L= value on M lines cannot be negative, which could cause
-		negative array subscripting.  Not a security problem since
-		this has to be in the config file, but it could have caused
-		core dumps.  Pointed out by Bryan Costales.
-	Fix -d21 debug output for long macro names.  Pointed out by Bryan
-		Costales.
-	PORTABILITY FIXES:
-		SCO doesn't have ftruncate.  From Bill Aten of Computerizers.
-		IBM's version of arpa/nameser.h defaults to the wrong byte
-			order.  Tweak it to work properly.  Based on fixes
-			from Fletcher Mattox of UTexas and Betty Lee of
-			Stanford University.
-	CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option.
-		Deficiency pointed out by Bryan Costales of ICSI.
-
-8.7.2/8.7.2	1995/11/19
-	REALLY fix the backslash escapes in SmtpGreetingMessage,
-		OperatorChars, and UnixFromLine options.  They were not
-		properly repaired in 8.7.1.
-	Completely delete the Bcc: header if and only if there are other
-		valid recipient headers (To:, Cc: or Apparently-To:, the
-		last being a historic botch, of course).  If Bcc: is the
-		only recipient header in the message, its value is tossed,
-		but the header name is kept.  The old behavior (always keep
-		the header name and toss the value) allowed primary recipients
-		to see that a Bcc: went to _someone_.
-	Include queue id on ``Authentication-Warning: <host>: <user> set
-		sender to <address> using -f'' syslog messages.  Suggested
-		by Kari Hurtta.
-	If a sequence or switch map lookup entry gets a tempfail but then
-		continues on to another map type, but the name is not found,
-		return a temporary failure from the sequence or switch map.
-		For example, if hosts search ``dns files'' and DNS fails
-		with a tempfail, the hosts map will go on and search files,
-		but if it fails the whole thing should be a tempfail, not
-		a permanent (host unknown) failure, even though that is the
-		failure in the hosts.files map.  This error caused hard
-		bounces when it should have requeued.
-	Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo
-		owned by bar mode 700 and inbox being set-user-ID bar stopped
-		working properly due to excessive paranoia.  Pointed out by
-		John Hawkinson of Panix.
-	An SMTP RCPT command referencing a host that gave a nameserver
-		timeout would return a 451 command (8.6 accepted it and
-		queued it locally).  Revert to the 8.6 behavior in order
-		to simplify queue management for clustered systems.  Suggested
-		by Gregory Neil Shapiro of WPI.  The same problem could break
-		MH, which assumes that the SMTP session will succeed (tsk, tsk
-		-- mail gets lost!); this was pointed out by Stuart Pook of
-		Infobiogen.
-	Fix possible buffer overflow in munchstring().  This was not a security
-		problem because you couldn't specify any argument to this
-		without first giving up root privileges, but it is still a
-		good idea to avoid future problems.  Problem noted by John
-		Hawkinson and Sam Hartman of MIT.
-	``452 Out of disk space for temp file'' messages weren't being
-		printed.  Fix from David Perlin of Nanosoft.
-	Don't advertise the ESMTP DSN extension if the SendMimeErrors option
-		is not set, since this is required to get the actual DSNs
-		created.  Problem pointed out by John Gardiner Myers of CMU.
-	Log permission problems that cause .forward and :include: files to
-		be untrusted or ignored on log level 12 and higher.  Suggested
-		by Randy Martin of Clemson University.
-	Allow user ids in U= clauses of M lines to have hyphens and
-		underscores.
-	Fix overcounting of recipients -- only happened when sending to an
-		alias.  Pointed out by Mark Andrews of SGI and Jack Woolley
-		of Systems and Computer Technology Corporation.
-	If a message is sent to an address that fails, the error message that
-		is returned could show some extraneous "success" information
-		included even if the user did not request success notification,
-		which was confusing.  Pointed out by Allan Johannesen of WPI.
-	Config files that had no AliasFile definition were defaulting to
-		using /etc/aliases; this caused problems with nullclient
-		configurations.  Change it back to the 8.6 semantics of
-		having no local alias file unless it is declared.  Problem
-		noted by Charles Karney of Princeton University.
-	Fix compile problem if NOTUNIX is defined.  Pointed out by Bryan
-		Costales of ICSI.
-	Map lookups of class "userdb" maps were always case sensitive; they
-		should be controlled by the -f flag like other maps.  Pointed
-		out by Bjart Kvarme <bjart.kvarme@usit.uio.no>.
-	Fix problem that caused some addresses to be passed through ruleset 5
-		even when they were tagged as "sticky" by prefixing the
-		address with an "@".  Patch from Thomas Dwyer III of Michigan
-		Technological University.
-	When converting a message to Quoted-Printable, prevent any lines with
-		dots alone on a line by themselves.  This is because of the
-		preponderance of broken mailers that still get this wrong.
-		Code contributed by Per Hedeland of Ericsson.
-	Fix F{macro}/file construct -- it previously did nothing.  Pointed
-		out by Bjart Kvarme of USIT/UiO (Norway).
-	Announce whether a cached connection is SMTP or ESMTP (in -v mode).
-		Requested by Allan Johannesen.
-	Delete check for text format of alias files -- it should be legal
-		to have the database format of the alias files without the
-		text version.  Problem pointed out by Joe Rhett of Navigist,
-		Inc.
-	If "Ot" was specified with no value, the TZ variable was not properly
-		imported from the environment.  Pointed out by Frank Crawford
-		<frank@ansto.gov.au>.
-	Some architectures core dumped on "program" maps that didn't have
-		extra arguments.  Patch from Booker C. Bense of Stanford
-		University.
-	Queue run processes would re-spawn daemons when given a SIGHUP; only
-		the parent should do this.  Fix from Brian Coan of the
-		Association for Progressive Communications.
-	If MinQueueAge was set and a message was considered but not run
-		during a queue run and the Timeout.queuereturn interval was
-		reached, a "timed out" error message would be returned that
-		didn't include the failed address (and claimed to be a warning
-		even though it was fatal).  The fix is to not return such
-		messages until they are actually tried, i.e., in the next
-		MinQueueAge interval.  Problem noted by Rein Tollevik of
-		SINTEF RUNIT, Oslo.
-	Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions
-		that have the hes_getmailhost() routine.  DEC Hesiod
-		distributions do not have this routine.  Based on a patch
-		from Betty Lee of Stanford University.
-	Extensive cleanups to map open code to handle a locking race condition
-		in ndbm, hash, and btree format database files on some (most
-		non-4.4-BSD based) OS architectures.  This should solve the
-		occasional "user unknown" problem during alias rebuilds that
-		has plagued me for quite some time.  Based on a patch from
-		Thomas Dwyer III of Michigan Technological University.
-	PORTABILITY FIXES:
-		Solaris: Change location of newaliases and mailq from
-			/usr/ucb to /usr/bin to match Sun settings.  From
-			James B. Davis of TCI.
-		DomainOS: Makefile.DomainOS doesn't require -ldbm.  From
-			Don Lewis of Silicon Systems.
-		HP-UX 10: rename Makefile.HP-UX.10 => Makefile.HP-UX.10
