发送的电子邮件会延迟几个小时到达

Question

This is my email sending code:

if(isset($_POST['contactname']) && isset($_POST['email']) && isset($_POST['message'])) {
  $contactname = $_POST['contactname'];
  $email = $_POST['email'];
  $message = $_POST['message'];
  $subject = "Ձեզ գրել են ձեր կայքից";
  $to = "stereoshoots@gmail.com";
  $headers = "From: ".$email;
  mail($to,$subject,"Ձեզ գրել է: $contactname \n $message",$headers);
  echo "E-mail-ը հաջողությամբ ուղարկվեց";
}
else if(empty($_POST['contactname']) && empty($_POST['email']) && empty($_POST['message'])) {
  "erroooor";
}

Everything is ok there, everything works without any errors, but the email is coming after few hours. How can I fix this?

Answer 1

如果发送了电子邮件，但要花费几个小时才能到达某人的收件箱，则问题出在邮件服务器上，而不是您的应用程序上。

Answer 2

1.View the "Email Header."

2.Review the "Received By" email server to determine the location/IP address causing the email delay.

The delay is not because of code.
