Enable bounce verification via Destination Controls. For more information, see 

.

The Bounce Verification Address Tagging Keys listing shows your current key and any unpurged keys 
you have used in the past. To add a new key:

On the Mail Policies > Bounce Verification page, click New Key.

Enter a text string and click Submit.

Commit your changes.

You can purge your old address tagging keys by selecting a rule for purging from the pull-down menu 
and clicking Purge.

The bounce verification settings determine which action to take when an invalid bounce is received. 

Choose Mail Policies > Bounce Verification.

Click Edit Settings. 

Select whether to reject invalid bounces, or to add a custom header to the message. If you want to add a 
header, enter the header name and value.

Optionally, enable smart exceptions. This setting allows incoming mail messages, and bounce messages 
generated by internal mail servers, to be automatically exempted from bounce verification processing 
(even when a single listener is used for both incoming and outgoing mail).
