NDR Bounce/backscatter messages still come through

CHEMIAGO

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

Michael

    Hi Michael,

    On your ES1100, are you using our Sender Genotype service at the MTA or policy level? There is a checkbox in that same section that can detect dynamic addresses. 

    There are several options that you can take, my first suggestion is to ask the enduser for the complete message and forward it to our labs for investigation.  Send the message to is-spam@sophos.com.

    The other suggestion is to contact our technical support team and they will be more than happy to assist in helping resolve this problem.
