 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")
