is one of your exchange servers, or an exchange server
with which you have an authenticated smtp connector?
if not, ignore it.

I keep getting these errors in my event log. I applied the
SuppressExternal registry hack, and turned the logging down to minimum.
I don't understand. It seems that mail flow is functioning these days,
but I wonder how concerned I should be about this:


This is an SMTP protocol log for virtual server ID 1, connection #233.
The client at "" sent a "xexch50" command, and the SMTP
server responded with "504 Need to authenticate first  ". The full
command sent was "xexch50 1008 2".  This will probably cause the
connection to fail.


Followed most of the instructions in this KB article:;en-us;843106&sd=ee 


I'm not sure how it is possible to raise the elevation of privileges for
the xexch50 command....
