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).
