only accept mail from efa users?

[cam]

Is there a way to make efa automatically drop mail for users that do not exist within it, instead of it actually hitting the mail server then rejecting?

The quickest way is probably to create a relay_recipients list in postfix. You can build it by hand, or if you have AD, check out this thread...
