126邮箱退信有源码：Content-Type: Message/delivery-status
直接简单屏蔽此类型不行，因为其下还含有子域，且含有附件，直接屏蔽解析不出附件了。


RFC822 为默认根，发现一个空行 其上对应的类型即为一个子节点
D:\svn\Client\ThinkMail_ClientWin_2013\trunk\src\thinkmail\mailnews\mime\src\mimei.cpp
mime_find_class (const char *content_type, MimeHeaders *hdrs,
         MimeDisplayOptions *opts, bool exact_match_p)
{

else if (!PL_strcasecmp(content_type+8,    "disposition-notification") )
                clazz = (MimeObjectClass *)&mimeNotShowClass;
else if (!PL_strcasecmp(content_type+8,    "delivery-status"))
                clazz = (MimeObjectClass *)&mimeNotShowClass;
else if (!PL_strcasecmp(content_type+5,    "rfc822-headers"))
          clazz = (MimeObjectClass *)&mimeNotShowClass;

上面这种方法 有问题，统一使用下面的方法：d:\svn\Client\ThinkMail_ClientWin_2013\trunk\src\thinkmail\mailnews\mime\src\mimeobj.cpp
MimeObject_parse_begin (MimeObject *obj)
{
//如果是不想显示的源码内容，在这里根据其父类型判断过滤下
   if ( obj && obj->parent && (!PL_strcasecmp(obj->content_type, MESSAGE_DELIVERY_STATUS) ||
          !PL_strcasecmp(obj->content_type, MESSAGE_DISPOSITION_NOTIFICATION) ||
         !PL_strcasecmp(obj->content_type, TEXT_RFC822_HEADERS)))
  {
          obj->output_p = false;
  }


thunderbird默认回执时产生两个附件Content-Type: message/disposition-notification; name="MDNPart2.txt"
Content-Type: text/rfc822-headers; name="MDNPart3.txt"

          !PL_strcasecmp(obj->parent->content_type, MESSAGE_DISPOSITION_NOTIFICATION) ||
