[cobalt-users] config error: mail loops back to me (MX problem?)

["Nic LAWRENCE" <nic@xxxxxxx>]

I've got a problem with sendmail configuration. I just added a new domain
"webbitch.org", but if I try and send a mail to an address at this domain I
get the following bounce back:

Sooo... I've checked out the MX entries, but they look fine:

I know that DNS is still propogating around the world for this particular
domain, so you may not get the same results as I did there, but the server
in question does in fact get the correct results so I don't think it's a DNS
problem.

In other posts in this group I've noticed reference to /etc/sendmail.cw ...
which rang a bell... but I can't find that file?!! ... all other email seems
to be working find on the server though.

Does anybody have any ideas? I'm desperate!!!

Thanks in advance,
