+ *
+ * The maildir mail-storage standard is a replacement for the traditional
+ * 'mbox' format, intended to remove problems with file contention, locking,
+ * reduce corruption in the case of a program or system crash, etc, etc.
+ * Fairly detailed description of it can be had as part of the Qmail MTA
+ * documentation, http://www.qmail.org/qmail-manual-html/man5/maildir.html.
+ *
+ * The general gist of the maildir approach is that mail is stored, one
+ # message per file, in a subtree of ~/Maildir. New mail goes in /new,
+ * the "spool" goes in /cur, and /tmp is available to MUAs &c. Mail is
+ * theoretically supposed to be removed from /new immediately by the
+ * MUA, but I've observed that with mutt 0.88, at least, it isn't if
+ * the mailfile was generated by an import script (e.g. mbox2maildir)
+ * rather than the normal delivery agent, presumably due to naming
+ * differences.
+ *
+ * Checking for new mail mostly entails checking the mtime vs. atime of
+ * every file in /new, and the number of messages in /new; if the latter
+ * increases, new mail was delivered -- if not, but the files' atimes
+ * are all later than their mtimes, the MUA read the /new spool.
+ *
+ * The specifications suggest skipping over every .file, but reading all
+ * the others -- I've extended this to include skipping of all non-regular
+ * files, which seemed to make sense -- define SUPPORT_MAILDIR_STRICTER to
+ * override this behavior.
+ *
+ * This process is more resource-intensive than the old scheme of merely
+ * calling stat() for a single file -- it's an O(n) rather than O(1)
+ * operation.
