SBS 2008 + Exchange 2007 - Strange Issue

Edit: if you PM me with your email address on the server I can try to check from outside...

See, here's the thing, I'm just the tech, they are letting me use an old email account they're erasing soon, so I wont have email access on their server in a little while. I'll try the telnet later, when i'm off-site, then I'll get back to you.

Nope, can't telnet in from a remote IP, even with the IP being allowed through the firewalls.

That's your problem. Apparently a firewall is blocking - whether it's a local software one or a hardware one.

And that would explain it. The client changed location now, moved all their IT equipment and their offices elsewhere, so now its all working.
