Topic: a little typo in this mask '#[\n\r:]+#s'
not sure but I think I've found a little typo in email.php
// Do a little spring cleaning
$to = trim(preg_replace('#[\n\r]+#s', '', $to));
$subject = trim(preg_replace('#[\n\r]+#s', '', $subject));
$from = trim(preg_replace('#[\n\r:]+#s', '', $from));
this line in the mask :
$from = trim(preg_replace('#[\n\r:]+#s', '', $from));
