IronPort Bounce notifications

[Amy Fowler]

So...we have Symantec DLP running.  When a user sends an email that contains data blocked by a Symantec DLP policy they get an email from DLP saying their email was blocked.  They also get an undeliverable from our Exchange environment saying ironport.domain.com #550 5.7.1 $SENDER$, the email was blocked because confidential data has been detected. ##

We want to stop the Ironport undeliverables from being sent to the users.  Is there a way to stop the Ironport from sending the confidential data ndr to Exchange?

Hello Claire,

I am not quiet certain what your process flow is actually, is Symantec DLP an external host the ESA delivers to, or is it installed on the Exchange server? I am asking because it seems there is a policy on Symantec DLP that creates a notification, but then passes the message to the exchange server.

Regards,

Andreas
