What counts as "full set of features"?

If you want to put together the pieces yourself, I recommend Postfix for 
the SMTP server, and Dovecot for IMAP/POP3. If you want webmail too, 
Roundcube is probably what you want, though I haven't had a chance to mess 
with it yet. Oh, and Postfix Admin is a nice web interface for managing 
domains and users, especially if you have multiple domains (but is still 
very useful if you have just one domain).

Of course, then you'll want to add in Spamassassin and maybe ClamAV (less 
necessary if you don't have Windows users). Amavisd-new can be useful to 
connect those with the SMTP server, but I ended up dropping that in order 
to save memory, instead connecting Postfix to proxsmtpd (to call 
spamassassin's spamc) and clamsmtpd.

I think Dovecot has a "sieve" filter interface available now, but I haven't 
looked into it lately.

The other major feature that people seem to want in a mail server is a 
calendar, but I don't have a solution for that (other than using Google 
Calendar). I don't entirely see the connection between email and calendar
