Then my advice would be: take the MTA you know best (postfix, qmail, exim, sendmail). If you know none, than postfix is a good choice (relativly easy to configure, good documentation available, some (very) good book available). I would recommend Kyle Dent's Postfix book published by O'Reilly. Nostarch is launching a postfix book soon, where one of the authors (Ralf Hildebrandt) is an ex-coworker of mine and proven postfix-guru. You're asking for the next steps. First I would install and configure postfix with amavisd-new, spamassassin and perhaps clamav. A very good documentation doing this is at: http://www.flakshack.com/anti-spam/ It's written for OpenBSD but you could easily transform it to Red Hat/Fedora. As for the IMAP/POP3/Webmail part I would recommend the courier-imap server and sqwebmail. Documentation for that is available at the according websites. List-disclamer: All these advices are only my viewpoint. It is clear that you can achieve the same goals with several different approaches. Therefore please no flame-war. I perfectly understand that your MTA and your IMAP/Webmail suggestion is as good as mine. :-) -volker
