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,

    As well as Jason's suggestion, I'd also recommend to check 'Search > Mail Logs'.  This will tell you if the message triggered another policy causing it to be delivered before reaching the Bounce rule.

    If you can't find the message in 'Mail Logs' it may be that the messages are arriving by another method - perhaps bypassing the appliance via a second entry in your MX record?  You can always check the message headers to confirm how the NDR arrived.

    Again, technical support will be happy to check your policy configuration and a sample of the message will definitely help them.

    Best of luck,

    Tom.
