_If_ I want to use this diff, Do this:
      cd /etc/mail
      ln -s ../../usr/src/contrib/sendmail/cf/cf/submit.mc `hostname`.submit.mc
 else a make in etc/mail does this, installing an uncustomised generic:
      cp freebsd.submit.mc `hostname`.submit.mc
      /usr/bin/m4 -D_CF_DIR_=/usr/share/sendmail/cf/ \
              /usr/share/sendmail/cf/m4/cf.m4 `hostname`.submit.mc > \
              `hostname`.submit.cf
 However, I currently merely note SASL things, but use the standard submit.cf
 until I get into what Submit can do for me.
