Hey, all. I've been asked to overhaul a postfix configuration and I would really appreciate any tips or advice that people may have on the subject.
I'm working on two servers : The first one receives mail for @example.org . The configuration isn't easy to read (hence the overhaul) but it looks so far to contain only aliases (so mail is received and goes back out instantly). The second server has the MX for @lists.example.org . As you can probably guess, it's a mailman-only machine. The main reason for the overhaul is spam. We're getting nailed as spammers by other domains because the first server redirects incoming spam to other mail servers and the amount of spam that needs to be moderated on the mailing lists is driving the list admins crazy. To solve this problem, we've decided to install spamassassin but I'ld prefer to manage only one instance of SA instead of two. What's the best way to do this? If I install SA on the first domain and remove the lists.example.org MX, spammers will still be able to send spam to it directly. Is setting up SA on both machines the simplest way to go?
