I have two Backend and one Frontend Exchange 2003 servers, suddendly all outbound messages sit in the Backend servers and there's nothing on the Frontend server. I've recreated the SMTP connectors and rebooted the servers. The IP address in the Virtual SMTP properties is the IP address of the Exchange server and no "All Unassigned". In event viewer on both Front end and Backend servers I have many "504 Need to authenticate first" "Xexch50 10842" errors
