Disable registration mail sending. Suggestion for solution

[janfer]

I wanted to disable mail sending totally since we do not have access to Internet where we run CTF. This is my suggestion for a solution.

--- config.ing.php -----
Config::set('MELLIVORA_CONFIG_EMAIL_NO_MAIL', true);

---- email.inc.php -----
// MOD to skip sending registrations mail first statement in function send_mail()
if (Config::get('MELLIVORA_CONFIG_EMAIL_NO_MAIL')){
return $receivers;
}
