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?

Thanks!
I don't use Postfix, but if you want SPAM to be bounced, then that's what is happening. Are you having problems with sending mail from your internal domain? If not, I'd leave well enough along. The SPAM is being bounced as I assume you desire. What's the problem?
