SMTP -> ERROR: Failed to connect to server: Connection timed out (110)

Question

I'm getting this errors while trying to send an email via PHPMailer:

Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /home/u722941258/public_html/old/account/access/mailer/class.phpmailer.php on line 1727

SMTP -> ERROR: Failed to connect to server: Connection timed out (110)

SMTP Error: Could not connect to SMTP host.

The PHP Code:

function send_mail($email,$message,$subject)
    {
        require_once('mailer/class.phpmailer.php');
        $mail = new PHPMailer();
        $mail->SMTPDebug = 3;    
        $mail->isSMTP();                                      
        $mail->Host = 'smtp.sparkpostmail.com';  
        $mail->SMTPAuth = true;                               
        $mail->Username = 'USER';                 
        $mail->Password = 'SECRET';                           
        $mail->SMTPSecure = 'tls';                            
        $mail->Port = 587;                                    
        $mail->AddAddress($email);
        $mail->SetFrom('[email protected]','Verificación de Cuentas');
        $mail->AddReplyTo("[email protected]","Soporte SOSgram");
        $mail->Subject  = $subject;
        $mail->MsgHTML($message);
        $mail->Send();
    }

Any solution?

Looks like outgoing port is blocked in your server. You can try using port 2525.

If that's also blocked, you can either open one of those two or use php client library which uses port 80/443 and it's very unlikely for those ports to be blocked;
