Sorry, I didn't give enough info in the previous message. Here is that I have...
A RedHat box the has 2 NICs, 1 on our internal network and 1 on our public network (from our ISP). The RedHat Box acts as a mail relay for 2 internal servers. It uses IP Tables for filtering. All the internal traffic is masquareded. Everything from the public network is blocked. I was checking the mailq for dead messages and I saw a ton of bounced messages. Subject: Cheap p0rn... free passes... I don't have too many options set in main.cf myorigin = something.com mynetworks_style = class #mydestination = $myhostname, localhost.$mydomain #relay_domains = $mydestination I assume I need to do something about relay domains. Any ideas on the correct syntax to allow only my internal hosts to send mail?
