Subject: [ExchangeList] Event ID 7010 


I get event id 7010 similar to the following 



Event Type: Error
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 7010
Date: 1/13/2004 
Time: 5:43:49 PM
User: N/A Computer: COMPUTERNAME
Description: This is an SMTP protocol log for virtual server ID 1,
connection #30. The client at "" sent a "xexch50" command, and
the SMTP server responded with "504 Need to authenticate first ". The
full command sent was "xexch50 1092 2". This will probably cause the
connection to fail. 

I know that this was discussed about a month ago and I searched the
archive but could not find a resolution.

I have an exchange 2003 server on Windows 2003 server. I am sending mail
to another exchange server. This other exchange server is not in my
domain and we do not share a forest or anything else. There should be no
authentication that takes place.

I found on Microsoft some mention that the "xexch50 1092 2" tells the
other server the size of some file that is coming. Maybe the size of the
email being transported. The other server is supposed to respond with a
BLOB (binary large object?) but that might have failed between the
servers. Could be the ISA server firewall might have blocked it. 

I looked in my ISA server and found Event ID 15105 ISA server detected
an all port scan attack from IP .... and this IP address is the same
address as the exchange server I am trying to send the email messages
to. Could ISA be confusing the blob and a port scan attack? That doesn't
make since but I am not finding a Event ID 20031 unknown smtp command
error in ISA that Microsoft says should be there if this is the problem.

Did anyone resolve this issue already?

I did the reg hack that was supposed to turn off the xexch50 on my end
and set the SMTP server to say helo rather then ehlo so I would not
advertise the xexch50 service on my end but the email is still sitting
there in the outbound queue and not going anywhere. The message in the
exchange server manager for the Queue just says "The connection was
dropped by the remote host".

These events indicate that the XEXCH50 protocol sink fired, but the
exchange of the blobs failed between the servers listed in the events.
