Hardly anything, given that it is almost completely done for you in the 
supplied /etc/mail/sendmail.mc file.  You just have to fix the 
intentionally-borked DAEMON_OPTIONS if you want to receive outside mail, 
fill in SMART_HOST if you'd like another machine to relay for you, and 
add entries in the access file for networks you want to relay for. And 
restarting the sendmail service will do the updates you need after 
changing these files.

Beyond that, you'd probably want to add a milter like MimeDefang so you 
can do anything complex and non-standard in perl.
