We are having an issue with legitimate NDR's and Out of Office messages being quarantined as spam. When I look at the reason it is almost always our "Bounce Messages" rule. i don't want to shut this rule off because backscatter spam has been a big problem for us. I have a support ticket open but it seems to have gone into the "Sophos Labs" black hole.
Any ideas for ensuring legitimate NDR's and Out of Office messages are delivered?
