This is the default head of forward mail in KMail: 

--------------------------------------------------
Subject: XXXXX
Date: Tuesday 18 November 2014
From: 10:24:08
To: A <someonea@example.com>
To: B <someoneb@example.com>
----------------------------------------------------

I checked the template of forward email, the head part is:
-------------------------------------------------------
Subject: %OFULLSUBJECT
Date: %ODATE
From: %OTIMELONG
To: %OFROMADDR
%OADDRESSEESADDR
-------------------------------------------------------

I think this is a template error.
