Good question. I'm no expert, but I know that MAC addresses can be easily spoofed by root. You can issue a command to a NIC card, to alter its MAC. It could be done at a sub-second rate too. So your email may not find it's route right. Wicked problem.

They network guys probably have a way to fight that though. ...oO( me hopes :-( )
