Exchange 2013 mail flow rule, Sender question...

I'm testing a transport rule that checks the sender address.  I want to verify that the sender address being inspected is the envelope address, seen in the header information as X-Env-Sender, I believe.  

Am I correct in this?

Another way of putting it is, I want to verify that the sender address being inspected is not the name that appears in the To:/From: field of a client message (which is known simply as the header address).
