Check the Return-Path header.

Is [EMAIL PROTECTED] in your whitelist_from? If so, there's you culprit.

To fix this, switch to whitelist_from_rcvd. NEVER use whitelist_from for
ANYTHING unless you've exhausted all other options first.

whitelist_from is trivially forgeable.

And before you complain about whitelist_from matching the return-path,
this header is no more difficult to forge than the real From: header.
whitelist_from'ing yourself or your domain is just asking to be abused,
no matter how many or how few headers it checks, they're all easy to forge.
