Sendmail handles SMTP, and Fedora includes a generic IMAP server as well 
(I don't remember who makes it...dove something, I think).

Sendmail's configuration files are in "/etc/mail".  The main 
configuration file is "/etc/mail/sendmail.mc".  It's fairly 
well-commented, so that should provide a decent start.  FYI the lines 
starting with "dnl" are commented out.

The default sendmail configuration should do relaying from 127.0.0.1.  
If you want your users to be able to send mail, you basically have two 
options:

    * allow mail to be relayed from a certain set of IP addresses (most
      ISPs do something like this)
    * force users to authenticate themselves before they're allowed to
      relay mail

I could go into a fair amount of depth with regard to either of these 
options, but it would take too much time.  I think the comments in 
"sendmail.mc" and the documentation at "sendmail.org" will give you a 
solid start though.

There should be almost zero configuration for IMAPd.  Install it ("yum 
install imapd"), enable it at boot time (with "ntsysv", for example), 
and your users should be able to log in.  Easy as pie.

Hope this helps a bit.
