Ok, I have a small mail server (Suse Pro 8.0) - around 90 users and it works great. Looking at SuSE Knowledge DB, i found that article about mail filters with procmail and postfix. For sure I could use procmail with sendmail as well all I'll need is to rebuild the sendmail.cf and enable the FEATURE(local_procmail). But when I do it, outgoing mail is not delivered anymore (no rules in procmail yet) the log is "Unrecognized host name outgoing.mail" while Incoming mail is correctly processed. FEATURE(dialup) nor FEATURE(promiscuous_relay) nor HACK(nodns) are enabled. Well, anyway my questions are: 1. It seems to me that Postfix has a better and easier integration with procmail, but would that be enaugh for changing from sendmail to postfix, assuming that I would have better tools to fight spam for exemple? 2. What would be the implications and performance impact? What else need to be considered, like users accounts, mailboxes, etc... 3. If there is a better place to those questions, please redirect me there, or any documentation available will do great.
