What's their relation to you?  Are they outside your network?  If so, have
you checked their DNS to ensure it is properly set up?  Wouldn't be the
first time that it wasn't (the best to go on is that other domains work, you
can receive email from other domains, but you cannot send to just one
domain.  That indicates that the one domain is somehow flawed from your
perspective. DNS is a likely place to look IMHO).

Thanks for your reply.  We don't use ipsec here.  I do appreciate the reply
though.  Also, I can get email from them.  Just can't send anything???

I had a problem where I installed IPsec on my exchange server. Then, as
a result, my exchange server couldn't talk to other SMTP servers that
were behind certain types of firewalls. Messages were not delivered to
those servers.
