I am having some issues with the SMTP server, when it sends emails to certain servers online it reports the following error:
This is an SMTP protocol error log for virtual server ID 1, connection #702. 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 1036 2 ". This will probably cause the connection to fail.
I have yet to figure out why this is?? I am using Exchange 2003 with SP2 and IMF v2.
