As quoted from <3031@haven.umd.edu> by louie@trantor.umd.edu (Louis A. Mamakos):
+---------------
| sendmail runs as root for the rather obvious reason that it needs to bind
| a socket to a restricted port number (25 == SMTP). Before sendmail exec()'s
| any processes, it does a setuid() to UID 1, which is daemon. None of the
| virus processes running on our system ran as root; rather they ran as
| daemon.
+---------------
Is it possible to run sendmail on a UUCP-only system without any setuid, but
instead setgid mail like the System III/V mailer? What kinds of changes
would it take? (Note that ncoast will most probably NEVER run any kind of
networking, so there's no reason for us to keep a setuid-root mailer.)
