I would like request to add feature for Mail Policy with PolicyD to make the Nethserver stronger and to stop Spam.
I think we evaluated PolicyD in the past, but I can't find relevant discussions.Here's what I found:http://dev.nethserver.org/issues/2343http://dev.nethserver.org/issues/1411http://dev.nethserver.org/issues/1409
Did you test PolicyD in production? Have you some numbers to share?
