We switched our MX record to to our Edge Transport server and were able to send mail out fine, but incoming mail is getting stuck on the way to the hub transport server. What could be causing this?

I do not have the Simple Mail Transport Protocol service listed as a service on either of these 2008 servers. Am I supposed to and if so why don't I see it?

My mx record was working correctly because mail was going out and mail was coming in. Just not pass inward toward hub transport.

Added SMTP Server feature. Can telnet from hub to edge, but not from edge to hub.

The problem ended up being McAfeee antivirus. Removed McAfee and then was able to telnet everywhere. Mail queue still wouldn't clear, so I did a new Edge Subscription and now everything is working.

You should not install SMTP service from the server manager, Exchange SMTP service is now called Microsoft Transport service.

Usually As you mentioned Anti-Viruse or firewall in between Edge and hub may cause such a problem

you should not install SMTP role from server manager.

Removed SMTP role, but the issue ended up being that the disk space on the hub/mailbox server was too low. Did a backup to flush the logs and mail started flowing in again.
