Hi, I'm still having some difficulty with trusted_networks, and believe it may be a result of a DNS issue?

Hard to trust a host > without proper DNS records. I thought I had a working DNS, though. localhost resolves, and so does 127.0.0.1. Here's an example with cnn.com. Is this correct? Received: from smtp01.example.com ([127.0.0.1]) by localhost (smtp01.example.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 30215-385 for <10...@example.com>; Wed, 25 Aug 2010 18:35:09 -0400 (EDT) Received: from i2.web2.mail.cnn.com (i2.web2.mail.cnn.com [157.166.236.129]) by smtp01.example.com (Postfix) with ESMTP id 04CC413D4020 for <10...@example.com>; Wed, 25 Aug 2010 18:35:09 -0400 (EDT) Here it looks like localhost didn't resolve properly, but I don't understand how this could be, because it is not only in the hosts file and in DNS, but it's also in the hosts file for postfix. Thanks, Alex
