This restricts sendmail to listening on the loopback address.  Just put
"dnl " (note that the space is required!) in front of that entry in your
sendmail.mc file and rebuild sendmail.cf.  That should allow it to
accept connections from other systems.

In other words, sendmail can't decide for certain if you're allowed to
relay mail through this server, and so rejects your message.

You need to add an entry in /etc/mail/access to allow you IP (NOT your
hostname!!) to relay mail.  Something like:

202.91.67.100	RELAY

and then rebuild the access map file.

Hmmm.  Not sure what happened there for you.

That will allow sendmail to accept mail FOR your domain, for local
delivery;  it will NOT allow you to relay mail for other destinations.

You should be able to make all of these changes from the appropriate
sections of the sendmail module in Webmin.

You need to install the sendmail-cf package.  I've yet to figure out why
it's separate in the first place;  it's pretty much NECESSARY to quickly
and easily reconfigure sendmail.

You may need to manually download the appropriate package and install it
from a shell rather than via Webmin;  I'm not sure if Webmin supports
fetching a package to install.  (IIRC it *can* install packages that are
already available as local files.)
