easy admin mail server recommendation requested

[Sam Hahn]

Gurus - I'm considering running Linux (preferably Debian) mailserver for 
one of my domains, vs an ISP (currently Verio - high rates). Do you (one 
or all) recommend a particular package that has easy simple admin in 
Debian (which distro?), and is reliable as a rock? Would it be PostFix, 
qmail, sendmail, etc? I would like mail handling (receive, send), POP3 
and IMAP access, spam blocking, virus blocking, and (extra-credit) 
mailing list management with self-administration (change address, 
digestify, archives, etc). I'd like LDAP or other directory integration 
to be optional, not required. (Do any of the Exchange work-alikes look 
ready?) (If this is a FAQ, please redirect, and apologies in advance for 
the bandwidth.) Thanks - Sam
