Following the advice of someone really helpfull here, I just installed Postfix/Dovecot (from rpms). I'm running CentOs 4.4. I followed this guide: http://www.howtoforge.com/linux_postfix_virtual_hosting
I've got two problems, a)my server is now listed as RCB, whatever that means, I suppose that's close to spamming. "0: Connection refused. Your IP address is blocked(Spamhaus XBL) - see http://www.spamhaus.org/query/bl?ip=216.32.68.90 "
That is bad news; you probably built an open relay. [...] But this all is really off-topic for an IMAP server list.
If you follow the trail of links you'll see that the problem is *not* open relaying. It is that the name the server is attempting to greet with does not resolve to its IP address. The page that Spamhaus eventually points to with specific information about why the IP address is listed and how to deal with it is http://cbl.abuseat.org/namingproblems.html
