Wrong smtp_password handling in functions_messenger.php

functions_messenger.php

contains function messenger($use_queue = true) {}
with global $config;
$config['smtp_password'] used all a cross the class,
but $config['smtp_password'] contains only ******** characters and not the actual password.
I've spend 2 days by switching different mail services to figure it out.
To fix thi issue i've just added $config['smtp_password'] = 'realpasswordhere'; next to global $config; in line 41
