NDR Bounce/backscatter messages still come through

So I've enabled the NDR bounce option on the ES1100 yet thousands of bounce messages from dynamic IPs are still getting through to one particular email box.  The appliance is updated to the latest OS and both Enable Bounce Address Tag Verification (BATV)" and "Treat all auto-responders identified by SophosLabs as bounces" are checked.

thx

  • Thanks for the responses.

    This is definitely coming into the appliance.  There are no logs associted with these NDRs.  as you can see below, the ES1100 is generating the NDR message.  These come about 10 a minute to just the one email address and nothing i can to will block the NDR.  I can't even block emails from "MAILER-DAEMON@es1100email.XXXXXXXX.local", the messages still come through.  I've created a rule in Outlook to permanently delete the messages as my work around.

    To Jason, this is how the filtering options are set in the ES1100 and I had already submitted the below message to is-spam@sophos.com
