sendmail issue

I've got an odd issue here. My setup is I have one server that is setup
as a relay server for my internal systems and it also receives email
from the Internet.

I have 13 other servers inside that relay any email they have through
the one server.

This is successful in all cases except to one specific domain I'm trying
to send email to BUT if I go onto the mail server itself and use mail -s
test it goes just fine but if I login to one of the
servers that relay their email through that same server it doesn't work
going to the same email address.

I suspect its a re-writing rule issue of some sort but I'm not sure.

Here is a tail -f capture of what's working and what isn't going to this
domain.

The first one was sent directly from mail001 where the last two entries
were sent from other servers that relay their email through mail001.
Emailing any other domain from any server that relays through mail001
that I've tested works so far except the mycingular.com domain.

Any ideas as to why and how to fix it?

Um, according to the logs you posted all the messages were accepted by
Cingular servers. So, from my point of view, it does not look like any
thing is broken. I suspect that the problem you are experiencing, that
we don't know any thing about, is based on some sort of filtering going
on at Cingular that is not being reported back to you.

I'd suggest that you contact someone at Cingular and inquire as to
whether or not they can / will confirm reception of the messages that
you are sending and what is / is not happening to them there.
