I am having issues with a client of mine. They are running Exchange 2003
Server with ISA 2004 acting as their firewall, they also have the IMF as
well, latest updates etc. 
The issue is when they send emails out to people who they have sent
emails to in the past before the server was setup it bounces back saying
the email has been delayed. Then a day or so later it says unable to
send the email to that person please contact the administrator of their
This doesn't tell me if it's the fault of Exchange or the fault of the
ISP in some way. I have check the SMTP logs and don't see anything that
could suggest their being a problem, when I connect via OWA and send an
email to my various accounts I get an email and nothing gets delayed, so
I am at a loss as to what it could be if it's related to Exchange!?
