I am running Exchange 2003 on a Server 2003 machine.  Recently have discovered that we had one customer that we could not send or receive emails from.  I turned up SMTP logging and sent test to the customer and this is the error message that I got:

Event Type: Error
Event Source: SMTP Protocol
Event ID: 7004
User: N/A
Computer: EXCHANGE
Description:

This is an SMTP protocol erro log for virtual server ID 1, connection #288.  The remote host "xxx.xx.xxx.xxx", responded to the SMTP command "rcpt" with "550 No such domain at this location (bill@domain.com)  ".  The full command sent was "RCPT TO:<bill@domain.com   ".  This will probably casuse the connection to fail.

I immediately received an NDR report, it said:

There was a SMTP communication problem with the recipients email server.  Please contact your system administrator.  <Exchange.ourdomain.com #5.5.0 smtp;550 No such domain at this location (bill@domain.com)>

This is the only recipient taht we are having trouble with but I need to get this straightened out.  I suspect that they are running some reverse lookup?  How can I fix this on our side?
