Are you providing a list of locally hosted domains with the
local-domains-file or local-domains-entry options? The

Faris, I doubt that what you wrote is true.
The “no MX” test applies to the domain of the email address in the
“From:” address in the header of the received email and not the
rdns-resolved domain of the IP address used to connecting to your

it is confirmed that your idea was wrong. I used a fake mail from in

This looks more and more like a bug to me.
