Its meaning does not appear to be officially documented, though it seems likely it is used by Gmail to ensure that legitimate replies to messages sent through Gmail will be accepted as legitimate regardless of any other indications which might otherwise cause Gmail to reject or spam-folder the message.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
