hi, i've just installed the oscommerce for the first time. The installation progress went well and without any trouble, but when someone wants to register the following errors show up:

 

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\xampp\htdocs\aravera\includes\classes\email.php on line 522

 

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\xampp\htdocs\aravera\includes\classes\email.php:522) in C:\xampp\xampp\htdocs\aravera\includes\functions\general.php on line 33
