My head's spinning trying to find the best email server available. Sendmail is the standard, but is very bulky, slow, and insecure. Postfix looks ok and is standard on Mandrake 9.0. I'm kinda leaning towards qmail at the moment. No binary rpms which i don't like, and it's not standard on Mandrake (I would love to use a standard proggie so I can update them all using MandrakeUpdate, then again maybe qmail would never need updating?).
I'm running Mandrake 9.0 on the server, and will use Spamassassin and Razor to help reduce spam. I prefer having spam controls set by the user (i.e. what rating to mark as spam, whether to mark or just delete, etc.) and so far it looks like with Sendmail this can be done, and with qmail it's partially possible though most of what I've read deals with server-wide settings, and not per-user. No info read on Postfix yet, I'm sure there's some info about it though if I keep looking.
Any thoughts?
