With some mail servers, it is possible to place a .fwd file in a users mailbox on the server that will blind forward any incoming mail to a given account. So, the e-mail path looks something like this:
SMTP Server –> Recipient’s Mail Server –>USERX (blind) and USER-INTENDED (as usual)
Thus, someones incoming mail can be read without their knowledge. However, I know that it is possible for the intended recipient to analyze mail in such a way that they can tell if it’s being intercepted upstream.
Does anyone know how this is done; and if so, what are some good tools/proceedures for analysis?
Thanks
