Look into qmail's VERP.  VERP will make you happy.  Very, very, very happy.

VERP (remote bounces) doesn't need to be parsed.  And Dan's QSBMF
(local bounces) is much easier to parse than DSNs.

You received bad advice.  First, because you are perfectly free to
modify qmail for your own uses.  Second, because very often, qmail
really *doesn't* need modification.  qmail is designed to play well
with other Unix programs, and can usually be extended without source
hackery or patches.
