It works.
I am starting to think the issue is with the ISP. Back when I had my
business connection with the same ISP a few of their routers had issues
with their MTU settings, every time my exchange would send out I would
get the same issue, and I could telnet to the mail servers from the
server side, however the ISPs routers would drop the information; now it
was only when I dropped the MTU on the linksys router which connected to
the Alcatel Speed Touch Home (PPPOE) that the email was going through.
Even the ISP at the time admitted to there being a issue their router
MTU's.
So I am going to get a colleague of mine to go through it with a fine
tooth comb, if it still doesn't work I am going to yank my Linksys that
has the MTU setting in it and switch for the one they use to see if that
fixes the problem on Monday.

Try initiating a direct connection from your Exchange server via telnet
to port 25 on their smtp server and iniate a test message manually and
see what happens.

Yeap. I am filtering Exchange on ISA, I can see the DNS being opened and
then SMTP.. The odd SMTP gets denied.

Is Exchange published on ISA server? Did you check the logs on ISA
server?

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
network.
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!?
