1. cd /etc/mail/
2. Edit `hostname`.mc (if it doesn't exist, "cd /etc/mail; make")
3. Add this next to one of the other FEATURE()
   lines: FEATURE(`no_default_msa')
4. Type: make install  (will overwrite sendmail.cf so if you have
   customized that file by hand, you will lose those customizations)
5. Type: make restart
