  download.oracle.com/docs...测试：A转到B ，B转到A。用C给A发邮件，A会转给B ，B再转给A，A不再转。在邮件头里包含了3次转发的路径Received: from mail-qw0-f47.google.com (unknown [...])by mx33 (Coremail) with SMTP id .--.1636S2;Sun, 01 May 2011 15:06:45 +0800 (CST)Received: by qwh5 with SMTP id ..6 for < *@163.com > ; Sun, 01 May 2011 00:06:42 -0700 (PDT)Received: by 10.229.77.12 with SMTP id ...; Sun, 01 May 2011 00:06:41 -0700 (PDT)X-Forwarded-To: *@163.comX-Forwarded-For: *@neverbest.com *@163.comDelivered-To: *@neverbest.comReceived: by 10.229.99.207 with SMTP id .; Sun, 1 May 2011 00:06:41 -0700 (PDT)Received: by 10.68.38.42 with SMTP id ...; Sun, 01 May 2011 00:06:41 -0700 (PDT)Received: from m12-70.163.com ([.]) by mx.google.com with ESMTP id ..48.2011.05.01.00.06.38; Sun, 01 May 2011 00:06:41 -0700 (PDT)
