Exchange 2010 - Issue with send connectors?
In the middle of an Exchange 2010 to 2010 migration and was testing mail flow. I had both servers listed under 'Source Server' in Organization Configuration, Hub Transport, Send Connectors.
I moved a user to the new server, then removed the old server from the Source Server list and sent a couple of test messages outside. I see emails queuing up on the old server. I was under the impression the source server was the server that would send out the emails...especially for a user that was on that server and database. Am I not understanding this correctly?
I have updated my firewall to use the IP of the new server for one-to-one NAT so PTR records match, etc.

Just sitting in queue.
Are you using a smart host in your DMZ or Edge server? If so can you telnet to the smart host from the new Exchange server?
Can you receive email from the internet?
Will.

451 5.7.3 Cannot achieve Exchange Server authentication." Attempted failover to alternate host , but that did not succeed. Either there are no alternative hosts, or delivery failed to all alternative hosts.
I have an internal relay connector set up, and have the old Exchange server listed in there. I just removed it. Made sure the 'Default' receive connector has 'Exchange Server authentication' ticked.

Please check event viewer and see if there any error. and how your Send connector is working. like sending mail to smart host or edge server?

Derp....my fault. I had another connector set up with the IP of the old Exchange server. It tried to use that connector since it was explicitly defined. Once I removed that mail flowed and out the correct send connector, IP, etc.
Would love to delete this question! ;-) I'm sure someone else will do something boneheaded like this, give them something else to check.
