Another shot in the dark... Do you use spam filtering? Buy blocked spam-server
lists from anyone? (Trend sell these) The company you cant recieve from might
have an ralaying server, wich have managet to get into one of these lists...

Their dns is seeing me fine. And I don't think I am doing any domain
validation :-) If I do, I sure don't know how I did it or how to undo
it.

also check to see what THEIR dns lookup says about you.. we've had it
before where someones had an old old old old record on their isp,
causing things to fail. although i guess seeing as it actually connects
to you but times out, thats probably not the cause.. youre not doing
some sort of domain validation on received mail are you?

Chris, after looking around, the DNS record for my MX record looks
right, even the reverse DNS looks right. I even use the name server of
ISP that my vendor is using and it points to the right ip address. So
far, he still can't get through while I am able to receive from
everybody else.

I would agree that it is most likely a DNS problem. It's most likely
related to your MX record, and not the DNS A host record.
I would do a simple NSLOOKUP using some online DNS lookup utility to
query for all MX records in your zone.

It is a DNS problem, I had the same problem a couple of weeks ago, and
received that same time out message.

Yes they are able to ping and they were able to telnet to my
exchange server. Weird part is that they don't have any problem sending
email to other people and I don't have problem receiving email from
other senders (as far as I know).

Can they ping your Exchange Server? Telnet to it? Sounds
like their problem, have them adjust their max connection time.

Just wondering if anyone can shed some light to this
mystery of mine. My exchange 2K server seems to be running fine but one
of our vendor can not get through. Everytime they send an email to us,
they get "Recipient's server exceeded time for connection". It seems to
be blocking their domain name but I can't find the block anywhere in my
system including firewall. Any idea?
Thanks for any input
Vince
