I have an SBS 2003 Sp1 with Exchange SP2. The event log shows up with the following error. Lots of them, Why! any hints?
"This is an SMTP protocol error log for virtual server ID 1, connection #566. The remote host "64.80.2.35", responded to the SMTP command "xexch50" with "504 Need to authenticate first ". The full command sent was "XEXCH50 1020 2 ". This will probably cause the connection to fail"
thanks
