smtp peer setting

[aminp30]

hi guys
I use php 5.6 so by default it sets verification of SSL certificate as true
I need to make it false
I found a code to set it in phpmailer.

PHPMailer::smtpConnect(
    [
                "ssl" => [
                "verify_peer" => true,
                "verify_peer_name" => false,
                "allow_self_signed" => true
        ]
    ]
);

How can I do it in vbulletin?
should I make change in class_mail.php file?
