Rejecting local mails with missing/empty subject?

[Mogens Kjaer]

Is there a simple way of adding lines to the sendmail.mc
file so that local users are not permitted to send mails
with an empty subject line?

I'm running sendmail 8.13.8 on a RHEL 5.3 machine.

Simple is a relative term.

If you define a rule to check the subject header, then it is NOT called for
an empty or omitted subject. However, one may set a variable when the
subject is present, then check for [the absence of] that variable in the
"check_eoh" or "check_eom" rulesets. Don't forget to reset the variable
somewhere (e.g. "Local_check_mail") in case multiple messages are sent in
one SMTP session.
