Just a note that if you're using 4.5-STABLE from 2002-03-25 or later,
and hence the non-setuid sendmail-8.12.x, then the trusted user stuff
should go into the configuration for the mail submission queue daemon:
that's /etc/mail/freebsd-submit.mc by default or whatever alternative
you select by setting SENDMAIL_SUBMIT_MC in /etc/make.conf
Cheers,
