Postfix Issue with mail bouncing...

[gbaughma]

Here's the situation.

I'm having an issue with postfix.

If a request for delivery comes in to an unknown local user, it rejects (the way it should). Unfortunately, that's leading to a lot of e-mail address harvesting (it just looks for ones that actually went through). But that's a different issue.

If an e-mail comes in that's not to my system at all, it "deferrs" it... and tries to deliver it itself.

In other words, something comes in to someone@mail.ru -- it actually tries to deliver it for them. This is bad.

Here's a snippet from the log....

Jul 20 09:15:28 londo postfix/smtp[3230]: 7D2FBDFE2B: to=<bfhyde@trespass.net>,
relay=none, delay=6846, status=deferred (connect to trespass.net[66.116.109.62]:
Connection timed out)

OK, I'm not trespass.net... and I don't want to DELIVER mail for trespass.net.... but it says "relay=none".... this is driving me nuts. Any thoughts?



Just my 2¢

relay=none" means that there's no relay host set up for that domain. It's normal.

Check your configuration files, especially in the "TRUST AND RELAY CONTROL" section. I'd first look at values for mynetworks, mynetworks_style, relay_domains, smtpd_recipient_restrictions.
