为什么我在Phpmailer中收到邮件延迟？

Question

I am using PHPmailer for sending mail, But email is sending so late to the customer, sometimes it didn't send. Can anyone tell me what is the reason?

My PHPmailer setting:-

public function sendemail($to,$msg,$subject)
{
    require_once(APPPATH.'third_party/PHPMailer-master/PHPMailerAutoload.php');

        $mail = new PHPMailer;
        $mail->isSMTP();                     
        $mail->Host = 'maddbas.nexcess.net';
        $mail->SMTPAuth = true;
        $mail->SMTPSecure = "tls";
        $mail->Username = 'myusername'; 
        $mail->Password = 'mypassword';
        $mail->Port       = 587;    
        $mail->setFrom('test@gmail.com', 'test');
        $mail->addReplyTo('test@gmail.com', 'test');
        $mail->addAddress($to);

        $mail->isHTML(true);
        $mail->Subject = $subject;
        $mail->Body    = $msg;
        $mail->send();
}

Actually, This isn't PHPMailer issue. This is happening because of your hosting provider!

Some hosting provider doesn't allow you to set from recipient except your own domain name or it may delay mail.

If you have cpanel access, You can track delivery report in email tab.

I would you like to suggest you to use strong email providers!
