MailScanner+SpamAssassin with Bayes and SA Custom rules is just as 
easy to set up and use. It is very configurable. Tack on ClamAV and 
bingo! Spam and Virus checking. Add MailWatch and Active Spam Killer 
(ASK) and you have a kick-butt mail system. You can even work 
procmail+bogofilter into this scenario!

Some Links:

http://www.mailscanner.info - MailScanner

http://www.mailscanner.info/install/spamassassin.shtml - MailScanner 
w/SpamAssassin - Though I used the RPM's from the SpamAssassin.org 
site and MailScanner worked just fine.

http://www.mailscanner.info/serve/cache/275.html - SA Custom Rules 
sets. 'Rules Du Jour' is awesome at downloading more common 'rules 
sets' that catch most spam when there are updates.

http://www.clamav.net - ClamAV Virus Scanner, loaded right from 
tarball, edit .conf file and walah! Set up Freshclam to pull down 
auto updates and your done!

http://mailwatch.sourceforge.net - Web-based front-end for 
MailScanner, installs in minutes and keeps track of statistics, even 
generates graphs! You can view messages that are quarantined. You can 
even use it to feed SA-Learn, SpamAssassin's bayesian filter, from 
quarantined messages. I also have spam trap email addresses set up 
for this purpose.

http://www.paganini.net/ask - Active Spam Killer. I added this as a 
final catch all for spam that does end up getting through (though 
this is rare) to the user. This is a challenge/respond system where 
senders that are not already on a whitelist must 'validate' simply by 
replying to a confirmation message. Works much like a mail list does, 
and end users can configure/manage everything through email once it 
is setup.
