msmtp was written by Martin Lambers <marlam@users.sourceforge.net>

The base64enc(), base64dec() and cram_md5() functions were adapted
from GNU Anubis, Copyright (C) 2001, 2002 The Anubis Team.

It helped a lot to look at the code of other GPL'ed projects 
(notably exim and ssmtp) to get some things right.

Other contributors to msmtp are listed in the THANKS file.
