I know mail can be forwarded, e.g. mail I receive will be sent to another account. However, can the reverse be true? That mail can be sent out and be delivered to another account before being sent to it's intended address.
Guy #1 sends an e-mail to Guy #2
Guy #2 gets the e-mail, and passes it on to Guy #3 as well; mail forwarded.
Guy #2 sends and e-mail to Guy #1
Guy #3 receives the e-mail on its way out.
If this is possible, how would I go about this on an Exhange server 2007? And what would this be called anyways? It can't be mail reversing!
