"If from Address does not match Return-Path then move to Junk Folder."
I can't find this capability in the message filter section and nothing
obvious to use in the add ons section.
Any suggestions?
Thanks.
Are you certain you want to use such a filter? Many newsletters and even
personal mail are sent with differing Reply-to's and From's. The fact
that there are differences in the Reply-to and From does not necessarily
indicate the message is spam.
You can filter on Reply-to, all you have to do is enter the header in
the relevant section of the filter (Custom)
I don't know of a means of comparing the From and the Reply-to though
