Old Qpsmtpd plugin open sourced

While moving my svn repos to git, I pushed out the source for a
Qpsmtpd plugin I wrote probably five years ago.  It is probably
severely outdated, but thought I would post the link here for
historical purposes:

Warning:  this code may be stylistically offensive, as well as just
plain crap in certain places :)
