I'm having some issues getting messages to relay from my web server through Exchange.
I'm currently running and Exchange server at home for testing and patch purposes, on a dynamic IP address. I've created a connector to link my Exchange to AT&T's SMTP server, which I authenticate to using my login info so I don't get blocked as spam. I can send email messages using Outlook Web Access with no problems.
However, I have configured my web server to be allowed to relay through the Exchange server, and configured PHP on that server to do the same. I have made this configuration numerous times on severaly different servers and environments. The problem I'm having is that each time a message is relayed through Exchange from the webserver (I'm sending a test message to my email address at gmail.com), the message gets stuck in the connector queue, with an ultimate result of failure.
The only error I can find is:
"The connection was dropped by the remote host."
The fact that I can send emails using OWA from the same email address makes me doubt its an issue with my ISP.
Thanks!
