Some email not received

I have an issue at one of my accounts that I think(???) lies elsewhere but
need some help to determine. My client has one entity that they routinely
communicate with via email. The last few days they have not been able to
receive ANY email from anyone at that company (domain). All other email
seems to arrive just fine.

All mail comes through SMTP; none through POP3.

Message tracking on my end shows no messages received from that domain.

SMTP logging shows no indication of inbound connection from that domain.

I have reverse DNS required, but have not done anything weird with it.

I turned off all sender, connection, recipient, ... filtering except IMF.
IMF is not deleted but rather archived or sent to users junk folder. Not
showing up either place.

No indication of it from Exchange Servers SPAM filter (Panda) and even if it
was being caught there would go to users SPAM folder in Outlook.

Is there anything else I can do to see if the problem is at my end. The
other end doesn't seem to anxious to troubleshoot saying it seems to go out
because they get no NDR.

Thanks for any suggestions.

The only way you can tell this is to go to their office and check things out
from there. If I were in your shoes and if they'd let me, I'd go in and
from their e-mail server try a telnet to port 25 of your customer's server.
If you can't or don't want to do that yourself, ask their postmaster to do
it for you while you're on the phone with them.

Thanks for the suggestion Ed,

They figured out it was their SPAM server goofing up the reverse DNS along
w/ some other things. But I really like your idea. Never thought about it.
