[tor-commits] [bridgedb/master] Refactor b.e.server.MailMessage class.

[isis@xxxxxxxxxxxxxx]

commit 9a1dbf55924ad71c1257d86caf6ad6cc65c78510
Author: Isis Lovecruft <isis@xxxxxxxxxxxxxx>
Date:   Mon Jun 2 20:58:23 2014 +0000

    Refactor b.e.server.MailMessage class.
    
     * ADD attributes so that the information about the incoming SMTP
       message is still accessible to the autoresponder while we're creating
       the reply.
     * FIXUP docstrings.
