[lug] SMTP delivery: No route to host

[William Jarosko]

FWIW,  I tried telneting to your box.  From here I got a response that
basically told me the machine it's sitting on is named oldschool and you're
running post fix.

220 oldschool.jackmoves.com ESMTP Postfix.

It also replied to a helo.

The server is my own. I know smtp works fine on the server because I have
many
other users that use it. It has to be a problem w/ my local boxes or the
route
it's taking to get there. But I don't understand why it's *only* happening
for
port 25.
