You'd also be blocking anything coming through forwarding addresses. I was
testing some code to do this just a few days ago (although I had it logging
instead of blocking), and caught several legit messages that really did
come from AOL, but were being sent to a forwarding address at another
location. By the time the messages got here, they were being sent from
puzzle.pobox.com with an aol.com sender.
If you know that nobody on your server has an account somewhere else with a
.forward file, it might be worth it. Otherwise, some people may lose all
mail from AOL, Yahoo, etc.
