We just recently migrated our SBS 2003 server to SBS 2008 using the sbsmigration.com as our guide. We had some issues with network card drivers that was causing the DC to go up and down randomly we finally got that issue fixed but now we aren't receiving external emails anymore and senders are receiving the following NDR. I have looked at the receive connectors and added anonymous, no luck. mydomain.org is already added to the accepted domains as well as mail.mydomain.org which has an MX record pointing to our public ip. Mxtoolbox is able to communicate with the server, but when I run testexchangeconnectivity.c
om tests it gets through everything but the actual sending of the message and I get the relay error. Any help would be appreciated.
Sending messages internally isn't an issue as well as sending messages externally it just is the messages externally trying to hit our server. We are running this with just one SBS 2008 server running exchange and hub transport is what we are looking to use.
Delivery to the following recipient failed permanently:
