I am at the tail end of a migration and trying to bring my new Exchange 2010 fully online... but I can't seem to get mail coming into the server from the Internet..  I run some tests and I get:

Diagnostic-Code: smtp;  530 5.7.1 Client was not authenticated

It can send mail out and I can send inter-office mail, but nothing comes in from the Internet..

Do you have a default Receive connector?

Yes, I have 2 receive connectors.. "Client EXCHANGE" on port 587 and "Default Exchange" on Port 25..

I CAN telnet into the server on port 25, but that's when I am running into the authentication issue..
