  • 1.  Bounce Attack and InBound filtering only

    I've a problem of Bounce Attack with a lot of NDR email messaging arriving and being delivered.

    I'd like to use this solution www.symantec.com/docs/HOWTO53629 but I think that it only works if we use SMG with OutBound Filtering features, is that correct?

    At the moment we're in the following situation, so I think that is not appliable...

    Do I need to put the SMG in "Inbound and outbound mail filtering" in order to achieve the desired result?

     

    Thanks!

    The string needs to be added to the email on the way out, so yes, the Messaging Gateway will need to be what delivers yoru email to the recipients. That way, when it comes back, we can validate the BAVT (bounce attack validation tag).
