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

The base64 and md5_hmac functions used by the built-in authentication code 
were adapted from GNU Anubis, Copyright (C) 2001, 2002 The Anubis Team.

The md5 implementation in md5_algo.[ch] was taken from popa3d 0.6.4.1
It was written and placed in the public domain by Solar Designer;
see the notes at the top of the files.
See README.md5 to find out in which case this implementation will be used.
