All good stuff.  What I really like with qpsmtpd, however, is the plugin
to cause it to refuse to accept mail to non-existent addresses.  The
dumb qmail smtp daemon would just take everything, to the point that our
mail queue ended up with tens of thousands of spams sent to addresses
which didn't exist.  The system spent all its time just trying to
deliver, then bounce them.

With qpsmtpd, such mail stays on the originating server, and it's their
problem.
