Which of the following are true regarding Bounce Management?

The correct answers are A , B , and C . Bounce Management in Proofpoint is tied to BATV —Bounce Address Tag Validation—which works by adding a signed tag to the envelope sender on outbound messages so that returned bounce messages can later be validated. Public BATV references describe this as a way to determine whether a bounce to your protected domain is valid and to prevent backscatter or false bounce spam. That directly supports B and C . The course-tested statement that log entries associated with this feature show mod=batv aligns with the BATV naming used for Bounce Management processing, making A the third correct answer.

The remaining options are incorrect because Bounce Management does not work by monitoring recipient mailboxes directly, does not exist to limit how many emails the protection server rejects, and does not bypass the recipient MTA. Its role is to validate bounces and stop forged nondelivery or bounce traffic from flooding users or systems. This matters because attackers often exploit spoofed envelope senders to generate backscatter and overwhelm inboxes with fake delivery failures. Proofpoint’s Bounce Management protects against that by tagging outbound envelope senders and validating the returned bounce path later. That is why the correct set is A, B, and C .
