But why are then the From: and Reply-To: headers affected? They won't 
appear in the SMTP protocol itself. And it's these fields that the patch 
addresses.

It's quite clear (and even stated in the PHP docs) that the described 
behaviour is true for the To: header. Though To: is set also by the 
first mail() argument. *

* A clever implementation of mail() would set the To: header only if not 
present in the additional header argument.
