Does anyone still use sendmail? I know that RHEL switched from sendmail to
Postfix with RHEL 6/CentOs 6.  In any case sendmail AND Postfix both  use 
procmail as the final delivery for "local" mail.  

Spamassassin does NOT take over the submission port. If you want spamassassin
to scrub spam at that level, you need to also install mimedefang as a Milter
(Mail Filter). Mimedefang will then pre-process incoming mail, both checking
any attachments for maleware and also passing mail messages to spamassassin to
check the email against spam filters and possibly mark it as rejectable, in
which case mimedefang can tell your MTA to reject the message. 

OTOH, you can have your .procmailrc run spamassassin directly or use spamd 
(spamassassin's deamon) and file spam into a spam folder or bounce it or any 
other thing Procmail can do.
