The problem is that they also have an exchange server trying to communicate with you. When that happens, it's told to try and authenticate and because it's not a member will likely fail. If this is an internet facing mail handler, you should not expect other hosts to have to authenticate in order to send mail to you. That would be a configuration error on your part and a silly extra verb on the part of Exchange. ;)

Hi all,


Installed a new SBS 2k3 box and get following messages in eventviewer:



ID 7010

This is an SMTP protocol log for virtual server ID 1, connection #278. The client at "193.173.22.154" sent a "xexch50" command, and
the SMTP server responded with "504 Need to authenticate first ". The full command sent was "xexch50 2204 2". This will probably
cause the connection to fail.

ID 7004

This is an SMTP protocol error log for virtual server ID 1, connection #292. The remote host "193.173.22.154", responded to the SMTP
command "xexch50" with "504 Need to authenticate first ". The full command sent was "XEXCH50 2376 2 ". This will probably cause
the connection to fail.


Only get this message from a few ip addresses....they are not member of the exchange organization but just other companies servers
who try to send mail....

Mail flow isnt working well from those senders as well....some mail arrive some dont....
Integrated windows auth is turned on at the virtual smtp connector as well.....

Is this a configuration problem on my exchange server or theirs?

All help appreciated.

Grtz Jorre
