There is actually a risk of false positives in doing that. Whether it affects you or not really depends on your users. Suppose user1 has accounts with you and some other mail server, but has their other mail forwarding back to their account with you. Then suppose [EMAIL PROTECTED] sends mail to [EMAIL PROTECTED] The server at them.example.net will forward it back to your server with an envelope sender address of <[EMAIL PROTECTED]> and recipient of <[EMAIL PROTECTED]>.
