使用PHP mail（）无法接收任何电子邮件。

Question

我一直在寻找解决方案，但找不到任何人。在显示代码之前，我想告诉您的是。我使用了Gmail电子邮件来接收来自无法正常工作的电子邮件，甚至在域中仍然无法正常工作的情况下创建了电子邮件。即使邮件正在发送，代码也能正常工作，但我无法收到它。

if(isset($_POST['forget'])) {
        $myemail = "admin@study-material.info";
        $email = $_POST['email'];
        $password = $_POST['password'];
        include("../functions/backend.php");
        $obj = new Crud;

        $uemail = $obj->forget($email);


    if(mysqli_num_rows($uemail) > 0){
        foreach($uemail as $show){
             $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()_-=+;:,.?";
$password = substr( str_shuffle( $chars ), 0, 8 );

            $obj->updatepassword($password,$show['Email']);



    $to = $show['Email'];
    $subject = "Your Recovered Password";

    $message = "Please use this password to login <br> password: " .   $password. "<br>Email: " . $show['Email'];
    $headers = "From: $myemail";

    if(mail($to, $subject, $message, $headers)){
        echo "Your Password has been sent to your ".$show['Email']."";
    }else{
        echo "Failed to Recover your password, try again";
    }

        }


    }



            else
        {

            echo "<script>alert('Email you intered not registered.');</script>";
        }
  }
