Exchange 2007 Transport (smtp) issues...

QQ. for the 2007 experts...I just recovered my 07 mail stores, but even though I recreated and  verified my inbound smtp receive connector, no matter what I do, I can no longer the the mail server to open a port 25 listen, thus get relay errors from my external (to host..inside my lan) spam server.  trying to telnet port 25 just keeps getting "Connecting To not open connection to the host, on port 25: Connect failed" errors.  I tried deleting and rebuilding the connector to no avail..I did however notice this onthe mail flow troubleshooter:

 Server exchange2007 has the Hub Transport server role and the following services are not started:  MSExchangeTransport. These services need to be running for mail to flow properly, then noticed my Transport service shutting down..then found this in the event viewer:
 The Microsoft Exchange Mail Submission Service is currently unable to contact any Hub Transport servers in the local Active Directory site. The servers may be too busy to accept new connections at this time.
BTW, got plenty of disk space..

This is the last hurdle to server recovery for me, and I'm finally stumped..

This can be a BackPressure issue - which can be lack of disk space and / or memory.  If you look at my article and change the edgetransport.exe.config file accordingly, then restart the MS Transport Service, does that help?
