Rule Config: Bounce Address Tag Verification (BATV)

Bounce Address Tag Verification (BATV) allows the appliance to distinguish between legitimate and illegitimate bounce (NDR) messages by tagging each message with a unique signature. Upon creation of this rule, all outbound messages will be tagged for the users and groups to which this rule applies, even if the rule is not active.

Note
All outbound mail must be sent through the appliance to ensure that BATV can function correctly.

Enabling BATV will not block emails that have been identified by SophosLabs as automatically generated responses. The Treat all auto-responders identified by SophosLabs as bounces option will cause any email messages identified by SophosLabs as automatically generated responses to be treated as bounces.

Note
Enabling this option will quarantine all auto-responses that have been identified by SophosLabs, such as vacation responders, and not just invalid auto-responses.

To activate BATV options:

  1. [Recommended] Select the Enable Bounce Address Tag Verification (BATV) check box to enable BATV.
  2. [Optional] Select the Treat all auto-responders identified by SophosLabs as bounces check box to treat all automatically generated responses as bounces.
  3. Click Next.
