I am running Exchange 2003 sp2 on a Win2003 Server and everything is running okay for the moment but in event viewer i am getting a bunch of 7004 7010 error(s):
This is an SMTP protocol error log for virtual server ID 1, connection #182. The remote host "18.104.22.168", responded to the SMTP command "xexch50" with "504 Need to authenticate first ". The full command sent was "XEXCH50 2088 2 ". This will probably cause the connection to fail.
Can anyone assist me with correcting this issue?
