How do I remove the wall of text when forwarding a message?

When I forward an email something like this displays: X-Spam-Flag: NO X-Authenticated-User: rshafer.abcoe.com X-Envelope-From: rshafer@abcoe.com Return-Path: <rshafer@abcoe.com> Received: from [10.0.0.188] (gateway.abcoe.com [23.25.128.41] (may be forged)) (authenticated bits=0) by mail238c25.carrierzone.com (8.13.6/8.13.1) with ESMTP id s97NKEZK007262 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES128-SHA bits=128 verify=NO) for <rshafer@abcoe.com>; Tue, 7 Oct 2014 23:20:17 +0000 Message-ID: <54347520.3000301@abcoe.com> User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Thunderbird/31.1.2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit X-CSC: 0 X-CHA: v=2.1 cv=J4OTsmXS c=1 sm=1 tr=0 a=hZHW8TegsZyqwlUGY8ln5w==:117 a=hZHW8TegsZyqwlUGY8ln5w==:17 a=ERoXFN_4AAAA:8 a=g0qM3YM6AAAA:8 a=by1oRRPI6K0A:10 a=62YsieI7ZYgA:10 a=IkcTkHD0fZMA:10 a=RcPUHUQIlc-5m50c8G8A:9 a=QEXdDO2ut3YA:10 a=-O4ZOXsQpbgA:10 a=69V9RB-pDj0A:10 a=U2gs4rMFwV0A:10 a=wBrtFnRrN2wA:10 a=RqlEVzNBZ_wA:10 a=HVUL1s51UsoA:10 a=u_lvPRDxc2kA:10 a=K42laXkL5c8A:10 X-CTCH-RefID: str=0001.0A020204.54347531.00C6,ss=1,re=0.000,recu=0.000,reip=0.000,cl=1,cld=1,fgs=0 X-CTCH-VOD: Unknown X-CTCH-Spam: Unknown X-CTCH-Score: 0.000 X-CTCH-Flags: 0 X-CTCH-ScoreCust: 0.000 X-Origin-Country: US X-WHL: LR How do I remove this?!
