[olug] Sendmail is making a fool of me.... help

[Jeff Hinrichs]

Brian,
Phil hit it on the head.  (see earlier message) the DaemonPortOption was set
to bind to 127.0.0.1, so I edited my sendmail.cf and restarted sendmail and
bada bing!

Thank you for giving me a hand.  I picked up some real practical
troubleshooting from you. (netcat, etc.) This will be handy for future
reference..

Thanks again, I owe you a beverage at our next social<g>.

-Jeff
