# wp-mail.php bug

 * Hey WP developers,
 * There’s a bug in current wp-mail.php which prevents it from correctly processing
   e-mails with subjects in quoted-printable encoding. In lines 53-55, we have this:
 * if (!preg_match(‘#\=\?(.+)\?Q\?(.+)\?\=#i’, $subject)) {
    $subject = wp_iso_descrambler(
   $subject); }
 * First of all, the regex check is incorrect – it should be
 * // No exclamation mark.
    if (preg_match(‘#\=\?(.+)\?Q\?(.+)\?\=#i’, $subject)){
   $subject = wp_iso_descrambler($subject); }
 * Even more, however, – this regex check is unnecessary here, since it’s done (
   correctly) in wp_iso_descrambler () anyway. So these three lines have to simply
   be replaced with:
 * $subject = wp_iso_descrambler($subject);
 * I’ve found this bug while experimenting with the blogging via e-mail feature.
   After the fix, everything works beautifully.
 * Thanks for the great product!
