This puzzled me; we should stop parsing in-body headers after the first blank line. But then I realized you probably meant the first "Subject" to be the real mail header.

I wonder if it would be more obvious with an example like:

  From: ...
  Date: ...
  Subject: the actual mail subject

  Subject: a very long
    broken line

Or something.
