Some servers use other port than 25 for mailing
It was my case, so i had to change the default "25" port to the one used by my server (in this case 2525)
Open
includes/smtp.php
edit the 25 in this line, with your port
if( !$socket = @fsockopen($board_config['smtp_host'], 25, $errno, $errstr, 20) )
That's all
