I'm new to the list (about 4 days new). I am running Fedora with sendmail, spamassassin and mimedefang as a mail gateway to my Exchange Server. I am excepting mail for a single domain and I have about 150 users(mail boxes).
Everything is working but I have a few concerns. I find messages in my outgoing queue for sendmail but the messages are addresses to other domains. Luckily I decided to use my Exchange Server as the Outgoing mail server and I configured my 3rd party firewall to deny the Fedora box access to port 25 outgoing. So, I am FaIrLy CeRtAiN that I am not being used as a relay. How do I prevent my Fedora box from accepting mail for other domains? (FYI: I receive approx 1500 mail messages per day (90% spam) LOL) (FYI: Only a few (1-5) messages are accepted for other domains per day) Also, Most of the spam messages that I receive are addresses to non-existing users... Mailing list I guess... Can I setup a way to accept mail for only a list of e-mail addresses? It seems like a shame that spamassassin and mimedefang have to work so hard scanning messages that are not even sent to a real recipient. Thanks, Michael New to Linux but learning fast!
