Unfortunately, LSMTP is not yet available for any Unix.

Yes, I get a lot of bounces, although it's not up to the level of
thousands a day (usually).  I like the idea of automating the handling
of them.  It's just that I think that DSNs are the best long-term
strategy for doing that.  If you run qmail on a machine with real user
mailboxes (not just a dedicated LISTSERV machine), you would be doing a
disservice to other LISTSERV sites, as you would not be generating DSNs
for bounced mail.  Recent versions of sendmail generate DSNs and
LISTSERV handles them automatically (although setting Auto-Delete
properly is still an art).
