Need some help.  My boss sent an e-mail to a recipient, and got the following bounceback message from System Administrator.  We run Outlook 2007 on Microsoft Exchange 2003.  Not experiencing any other bouncebacks currently

The following recipient(s) cannot be reached: on 4/1/2009 12:53 PM
            There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.
            <myserver.mydomain.priv #5.5.0 smtp;550 No such user (>

Can you help me out with this and what to look for?  Is this on my side or on the recipients side.  I would think it is the recipient's side.  Thanks.
