CC Duplication

[markman]

If any of my users receive a mail with CC addresses specified, the server
instantly forwards/relays the message to the CC Recipient. Consequently the
CC recipient receives two copies of the mail. Both appear to have come from
the original sender however examination of the headers reveal that one came
from the originator whilst the other was despatched by our server.

At a complete loss - fully SP'd and patched; No open relays; No mailbox
rules running. Help!!!

Look for a server solution since htis is where the issue happens.
