X-PHP-Originating-Script: 0:func.inc
MIME-Version: 1.0
Content-Type: multipart/mixed;
 boundary="=_fce46910f3b128bcbbfed9efa85812c9";
 boundary="=_fce46910f3b128bcbbfed9efa85812c9"

Reinstalling php-mail-mime brings it back to the bad headers, so these 2
files are indeed responsible. I dont have much time today anymore, but
