[flaggi]

Hey.

Is here anyone that may have an idea whats causing the following issue?
I can´t use the notify customer option when updating orders, when i do i get:
Notice: mail(): Policy restriction in effect. The fifth parameter is disabled on this system in /****Jadajada****/includes/system/versioned/1.0.5.4/email.php on line 390 Warning: Cannot modify header information - headers already sent by (output started at /****Jadajada****/includes/system/versioned/1.0.5.4/email.php:390) in /****Jadajada****/tempadmin/includes/functions/general.php on line 36

The fifth parameter is disabled on this system

Remove the "-f$from_addr" parameter from the mail() call.
