Gentlemen, I wish there was a whitelist_from *...@facebookmail.com rule that would use the Return-Path field,
$ egrep '^(From|Return-Path):' a b a:Return-Path: <notification+zj4oo-6-6...@facebookmail.com> a:From: Facebook <notification+zj4ooo699...@facebookmail.com> b:Return-Path: <chanetho...@hotmail.com> b:From: Facebook <update+3ttttttxy...@facebookmail.com> as that is much more reliable. I see there are other whitelist_ rules, but none that can use what is already staring one in the face in the headers, and does not need to go on the network to work.
