I have a Server running Winsows Server 2003 and it is also my Exchange server running Exchange 2003 SP2. I am getting the following Event ID errors multiple times.

Event ID: 7004

This is an SMTP protocol error log for virtual server ID 1, connection #132. The remote host "216.174.163.10", responded to the SMTP command "rcpt" with "550 unknown user <lisam@springnet1.com>  ". The full command sent was "RCPT TO:<lisam@springnet1.com>  ".  This will probably cause the connection to fail.


Event ID: 7010

This is an SMTP protocol error log for virtual server ID 1, connection #131. The remote host "128.174.79.241", responded to the SMTP command "xexch50" with "505 Authentication required  ". The full command sent was "XEXCH50 2128 2  ".  This will probably cause the connection to fail.

Any suggestions?

The first one means what it says - unknown user. The server that Exchange has connected to doesn't recognise the user the email message is being sent to, so has dropped the message.

The second is a message generated when Exchange thinks it is talking to another Exchange server. Are you using a smart host anywhere in the configuration of the Exchange server? That can cause those types of messages to be generated.
Do you recognise the IP address mentioned? It belongs to the University of Illinois if that helps.
