Re: Postfix OS X Server

Thank you for your input Victor. My sender_access file only contains OK rules no reject rules. Should I just remove the sender_access list? I don't know that it is really helping or that I have it setup properly if it is full of OK instead of REJECT. Do you think this is the culprit to my problem?

Postfix OS X Server

I think we are having directory harvest attacks on our OS X Server. I am not familiar with postfix and we use this server primarily to send mail out from our web servers on the same subnet. There are a few account that receive mail and are popped but no mail really stored on the server. I have OS X

Multiple Instances

Catch-all alias with luser_relay

I run a small mail server which receives mail for a few domains. So far I've been unable to get a catch-all address working. I tried these settings: local_recipient_maps = luser_relay = m...@jonathangazeley.com Emails to t...@jonathangazeley.com (which does not exist) are rejected with 550.

can you greylist custom header checks etc?

Just curious if it's possible to pass messages that match certain header checks to postgrey instead of flat out rejecting them. The reason I ask is that I was trying out some of the S25R http://www.gabacho-net.jp/en/anti-spam/anti-spam-system.html rejection rules, and started noticing false positi
