Exchange outgoing mail Q

[MobileTechie]

I've been helping a friend with an Exchange mail problem. He cannot send outgoing mail. When Outlook clients send the mail it just sits indefinitely in the Exchange queue and no errors are returned.

Outgoing mail is setup using an smtp connector - to the smtp relay supplied by his ISP.

I can ping that relay server but cannot telnet to it. I can however telnet to other mail servers (such as my own for instance). I can telnet to that relay server from my own computer. He's contacted the ISP who insist there is no blocking going on and that they can see him connecting to them.

Any ideas?

Have you checked the logs (Event Viewer and others)?

Yeah nothing relevant in them as far as I could see.

I'm intrigued as to how the scenario I outlined is even possible. Why can I not telnet to that particular mail server from that particular computer yet telnet to other servers and telnet to that server from other computers?

The only thing I can think of is if the ISP is blocking that server, which they say they are not?

Make sure the SMTP connector service is running.
CMD services.msc

Set the logging within Exchange to 'maximum' and enable all events to be logged.
I would then reset the server and check that the various services are running as per the post above.
After a couple of minutes you should have some interesting data in the event viewer.
PS - the queue isn't 'on hold' is it?
