I can OWA into any account just fine from remote locations. I have recreated send and receive connectors a couple different times. I can telnet into the server while offsite using the FQDN and port 25. When on the Exchange server itself I cannot telnet to it, though I'm not sure if that is normal or not. The old server is still up and running and was sending and receiving email just fun until I changed my port forward in my router to point to the new server to test mail flow. All but one of the email accounts are still on the old server but I did move one account to the new server for testing. I can OWA into that account without issue. If i go into my queue on the server i have approximately 30 email in there and and error message. 451 4.4.0 Primary target IP address responded with: "421 4.2.1 Unable to connect." The mailflow troublshooter comes back with "5.3.3 unrecognized command" which from research I see can be due to lack of space on the hard drive, that is not the case on this server.
Aside from that I have tried too much to list. Suggestions would be appreciated.
*Old server is Server 2008 SBS
*New Server is Server 2012 with Exchange 2010 SP2
