Lately we've been getting a run of spam purporting to come from Hotmail
or Yahoo senders, and unfortunately both of these domains use "~all" in
their SPF records. Not one of these spam messages are originating from
the genuine hosts.
Received-SPF: Softfail (domain owner discourages use of this host)
identity=helo; client-ip=199.243.243.50;
helo=google.com; envelope-from=109imfbz1de@yahoo.ca;
receiver=receiver@example.com
Received: from google.com (cyginternet.cygnuscorp.com
[199.243.243.50])by smtp3.domain.com (Postfix) with ESMTP id
64BCB208091for <receiver@example.com>; Wed, 25 Feb 2009 06:15:13 +1100
(EST)
Is there a way of making SPF "enforce" a real fail on a per-domain
basis? I'm using postfix-policyd-spf-python.
