I have a colleague who routinely asks for a Read Receipt for absolutely
everything, which I find annoying. He has resisted all efforts to stop
this, what I consider to be, bad practice.

Is there anyway within an Outlook 2003 V 11.0 Microsoft Exchange Server
environment that I can, without sending a Read Receipt, prevent the dialogue
box asking me whether or not I want to send a RR from popping up when I
receive messages from this user?

Could a rule be developed to do this?

Ideally I would like to be able to do this for this one user only, so that
if anyone else asked me for a RR I could continue to decide on a case by
case basis.
