I'm using spamassassin (3.2.5) with Postfix and DKIM-Filter 2.6.0.
Spamassassin runs as content filter (spamd/spamc) like this:
http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix
In local.cf I've set the "report safe = 1".
Sometimes I see E-Mails with a DKIM-Header like this:
Return-Path: <m...@example.com>
Delivered-To: m...@example.com
Received: by tux.example.com (Postfix, from userid 5000)

with SpamAssassin (version 3.2.5);
In other E-Mails this header is missing which seems that this should be
correct...
Return-Path: <kturbo...@email.com>

From: "Brianna Block" <kturbo...@email.com>
To: "Me" <m...@example.com>
I've no idea why this additional DKIM header is inserted or not.
In all cases the mails gets correct detected as spam and the spam report is
attached to the mail but in some mails I see the DKIM header.
