I want to run a program when postfix has successfully sent out a mail (local or remote). I would like to pass the headers to program and if possible also the destination ip or address (exclude spam filter delivery).

I just have an idea: Delivery Status Notification processing via uniqe transport program, but I'd prefer the above.

My goal is to be recorded lifetime (events) of email: it came, it went out (from, to, subject, datetime, message id, message status: bounce, sent). I would only need the state of the outgoing mail, because incoming and bounce program is working.

It is possible to trigger a program (similar to a transport pipe/spawn) or DSN "cheat" stay?

Thanks in advance for any reply!
