>From experience (2000+ users, lots of research) I would recommend either qmail-ldap or Postfix for mail delivery (MTA) and Courier IMAP for IMAP and POP service.
LDAP is essential if you plan to run a serious mail server. There's very few alternatives to a well-managed LDAP server for your user user directory. qmail-ldap is very good for this. If you just want a mail server for yourself without LDAP, Postfix is great. I like it a lot for small setups (less than 100 users) but Qmail is better for large setups based on my experience. You should deliver mail in the Maildir format. mbox format is easy to understand but terrible in almost every other way. A huge plus to Maildirs is that you can NFS-share them safely. Courier IMAP is very reliable and standards-compliant. People also like Cyrus and Binc, but stay away from UW IMAP. It's s-l-o-w (at least partly because of the mbox storage). I can go into details on any of these if needed. Ted _______________________________________________ Boston-pm mailing list [EMAIL PROTECTED] http://mail.pm.org/mailman/listinfo/boston-pm
