Yes, exactly and the point several of us have been making is that this is (a) easy (well, provided you're using a quality MTA; if not, then switch to one) (b) running a sane mail system (c) fast (d) resource-friendly and (e) most important of all, the _only_ way to avoid sending UBE in response to forgeries (which are not going away any time soon or quite possibly ever). (Please note: there are no exceptions to the UBE specification for DSNs. If DSNs are: - sent to forged senders (thus unsolicited) - in bulk (thus bulk) - via email (thus email) then they are UBE, which is THE definition of spam -- and which deliberately omits any mention of content, purpose or other things that are irrelevant to the spam/not-spam question.) ---Rsk
