Drop Mail for unknown locals (Postfix)

anon220 · 10-22-2007, 06:25 PM

Any idea how to drop mail for an unknonwn local recipient instead of bouncing it with Postfix?

By default postfix doesn't bounce mail to unknown local addresses; it rejects it. Is the mail in question being rejected or bounced?

They're being bounced, I'd prefer that they're just rejected.

Let's see logs showing everything from submission to bounce, and the output of "postconf -n".

Ok, I'm a dunce. ;-)

I couldn't find any bounces in the logs... so I looked at what was piling up in the queue and it's not bounces from my side, it's mail that can't be delivered to the destination (off my server).

Will those mails stay in the queue forever or do they get purged after some time?

Those mails will stay in the queue for 5 days, and further attempts will be made to deliver them. If delivery is not successful by then, they'll be returned to the sender. You can also purge them manually with postsuper.

Ah, ok.

Is the number of days they stay in the queue configurable, to make it longer or shorter? And can they be dropped instead of returned to the sender?

Yes, the queue life time is configurable using maximal_queue_lifetime. There are many parameters that are configurable. To see all of them:

Code:

man 5 postconf

I don't believe you can change the action taken on expired mail.

Excellent info there. Thanks for the help!
