BoxTrapper is part of cPanel's webmail engine, to help protect you from unwanted email. The filter works through “challenge-response” verification. When an email is sent to an account that has enabled BoxTrapper, BoxTrapper automatically sends a verification email in response. This verification email requires the original sender to send a reply or click a link. After the sender does this, BoxTrapper delivers the original message to the intended recipient’s account. The goal in enabling BoxTrapper is to block email senders who do not reply to the verification email or click the verification link.

Any email account with BoxTrapper enabled should use the Box Trapper Forward List feature.
