I use two copies of sendmail.  The publicly executable is setuid
"smtpd".  A second copy is not setuid and is executed only by root
at boot.  I use RunAsUser=smtpd so sendmail run as smtpd after a
connection is accepted.  /var/spool/mqueue is owned by smtpd.

The only gotcha is that user directories must be at least o+x so
sendmail running as smtpd can read .forward files.
