This is a Python library for the generation of email authentication headers.


The library can perform DKIM, SPF, and DMARC validation, and the results are
packaged into the Authentication-Results header.

authenticate_message(message, "example.com", ip='192.168.50.81',
     mail_from="test.com", helo="domain.of.sender.net")

Authentication-Results: example.com; spf=none smtp.helo=domain.of.sender.net smtp.mailfrom=test.com;
    dkim=pass header.d=valimail.com; dmarc=pass header.from=valimail.com
