I've implemented this feature in qconfirm, and use it successfully for a mailing list for about one year. I stopped using it for my main mail address because the delivery confirmation requests no longer can reliably be identified as delivery notifications, as they're no more sent with an empty envelope sender. Beware, your confirmation request messages possibly get challenged. I developed this to reduce the number of double bounces, not to make the pending queue smaller, though. And I developed it for qmail only, which makes it _a lot_ easier. See http://smarden.org/qconfirm/bounces.html if you are interested. Some things to consider: Only process bounces created by the local MTA (confirmation requests that are rejected on SMTP level, this prevents processing of remote auto-responder messages). Don't delete the message after the first bounce, send a confirmation request reminder after some days, and only remove the message if the address bounces multiple times.
