Block emails having different source and reply-to address....

[Michael Masse]

Another useful tool for this is called mailfromd.   It works very well for this sort of thing, but as others have said, mailling lists will break with this and unfortunately more and more legitimate email senders seem to be using what I call 3rd party pseudo-spam services.
