I'm installing sendmail for the first time and I'm having a problem<g>
Sendmail version: 8.11.2

Short Version:  Sendmail is refusing to accept mail from the outside world.

Long Version:
Send mail is running, and I can send mail to other accounts on the box.  I
can send mail out to the 'net.  But when I send mail from the outside in I
get the following error.
88888888888888888888888888888888888888888888888888
The following addresses had transient non-fatal errors -----
<jlh at xxxxxxxx.com>

   ----- Transcript of session follows -----
<jlh at xxxxxxxx.com>... Deferred: Connection refused by www.xxxxxxxx.com.
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old
8888888888888888888888888888888888888888888888888
I've blanked out the domain with xxxxxxxx.com but you get the idea.

I just ran a port scan and port 25 is not showing up.  SSH and HTTP are,
which I want.
I poked a  hole through ipchains:

Suggestions?

Thanks,
Jeff
