Hi all. I need help from an Exchange expert. I am running MS Exchange 2003 (SP1) on a server running on Windows Server 2003 (SP1). We have a small office (20 users) w/ all users connecting to Exchange via Outlook. Roughly two months ago I set up an SMTP connector to forward ALL outbound e-mail from our office to our web / internet e-mail hosting svc's (GoDaddy) outgoing mail server because we were having problems sending outbound e-mails to larger ISP based e-mail accounts such as aol.com, hotmail.com, optonline.net etc... The connector was working beautifully up until yesterday when all of a sudden messages started just accumulating in the connector’s queue and were not being sent. I checked and re-started all Exchange services, re-created the connector (multiple times), and have even re-booted the phsyical server itself twice. No luck. I also contacted GoDaddy to see if they were having any problems or made any changes on their end. They said all was fine on their end, w/ no changes made. Also, I can send e-mails directly from there server.
What’s weird is that if I remove the connector, I can send outbound e-mails to addresses that don’t have all of the restrictions that the larger ISP accounts do. But if I put the connector in place, it seems that no messages get out to any external recipients whatsoever.
I should also note that we are not having any internet connectivity problems, nor have we made any changes whatsoever to our firewall settings or to the server running Exchange. It just seems to have started out of nowhere. I am not an Exchange expert so I may very well be overlooking something obvious. How can I resolve this??
