SMTP: sendmail is part of the base system and is pretty powerful but has a
steep learning curve. There are alternatives available in the ports, one of
the more popular being postfix. Others such as qmail may also be worth
POP, etc.: I highly recommend dovecot. It's efficient, pretty easy to
configure, and can handle almost any setup you can imagine. You also get
IMAP with this, which even if you don't want on its own you will want to
use with your webmail package.

Admin: webmin provides a reasonably secure web-based frontend to many
different admin. tools and allows you to grant different levels of access
to each tool to different users. Virtualmin might be an even better match
for what you're after.
Webmail: For features, go with Imp and any other parts of the Horde suite of
applications that interest you. Horde's groupware package is starting to
get pretty polished, and the individual components (mail, calendar, address
book, tasks, etc) are all quite mature. Setup and config is a bit on the
complex side, but there's work going on there and much of the initial
config is now web-based. Other popular and simpler webmail packages
include OpenWebMail and SquirrelMail.

I use clamAV on my mailserver, works great and keeps itself up-to-date
pretty well. Easy integration with sendmail via a milter. For spam you'll
likely want a combination of techniques. SpamAssassin is a good starting
point. Also look at the DNS black- or greylisting features of your SMTP
program (I use a couple realtime DNS blacklists with sendmail). Depending
on the types of messages you're hoping to stop/detect, you might also want
to look at MimeDefang.
Everything above is in the ports. You have a lot of options so it's just a
matter of nailing down what you want in terms of features and then
selecting the best tool for the task.
