Subject: stop relaying non existing users

Hi All

Does anyone know if it is possible to stop the relaying of non existing
users to my exchange server.

Postfix relays everything for my domain existing or not. Is there any way
for postfix to check if the user exists before relaying the message. At the
moment all non-existing user messages are accepted by exchange and then
exchange sends out a non-existing user reply to the sender.

Thanks in advance

Steven
