Replies with format of "Date: Fri, 19 Oct 2012 16:43:35 +0000 To..." are posted as comment text

When commenting via email this string consistently slips through and appears in the comment text:

> Date: Fri, 19 Oct 2012 16:43:35 +0000 To: example@example.com

Noticed this in multiple instances on one WP.com site so far. [For example](http://carryoncouple.com/2012/10/26/a-strange-unwelcome-visitor/comment-page-1/#comment-61).

Not sure of email client used or any specific rules set.

Start by reproducing an email comment containing the quoted Date and To headers, using the example linked in the issue as the reported behavior. Trace how incoming email is parsed and converted into comment text; done means those header lines are excluded while the actual comment remains intact, including for the unknown email-client variations.
