You've gotten some good responses, but like Chris I will share my experiences:
We use Exim4 with sa-exim. Sa-exim also adds some greylisting abilities. More importantly, Exim4 has LDAP query abilities so we can query our Active Directory before accepting a recipient. This is essential in our situation since we are a university and have a very high turnover in email addresses. My logs show that over 60% of our incoming email is to invalid addresses. If it wasn't for LDAP queries, we would have scanned all that email for spam and viruses and then let the Exchange servers drop the bad addresses. Out of curiosity, does anyone know what other MTAs might support LDAP queries? Have fun!

What are my options? I've seen MIMEDefang and spamassass-milter (which won't compile on my completely generic redhat fc2 box). Are those my only real options?
