[lug] sendmail not accepting

[Riggs, Rob]

I think the problem was discussed on this list a while back. The problem is
that Red Hat configures sendmail to bind to localhost only by default.

Comment out the line below from the /etc/mail/sendmail.mc (put a 'dnl ' in
front of it) and rebuild the sendmail.cf file (instructions at the top of
sendmail.mc).

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

Just for kicks...
