We've just started switching some of our MX's over to postfix and I must 
say that I've been pleased with the experience.  But regardless of whether 
you're moving to postfix or stuck on sendmail the next advise I felt was 
less good:

Use MailScanner!** Use three virus checkers (f-prot is cheap and clamav is 
free and there are plenty of others out there), mixin SA rules, filename 
checking, add lots of things that you can optionally adjust and let 
MailScanner keep it all straight.  It works with postfix, sendmail, qmail, 
and a few other MTA's are rumored.  It'll keep your virus definition files 
up to date whether you're using one antivirus engine or twelve.

Its absolutely awesome open source and it is well supported by the primary 
author Julian Field and a very active mailing list community.  And its in 
Perl and Perl is a wonderful language (or so I've heard).  :)

filtering/tagging system because of MailScanner.  So...
