mail（）函数正常工作，但邮件未送达

Question

即使mail（）函数正常运行，我也没有在我的Gmail邮箱中收到邮件。我已经配置了php.ini文件和sendmail.ini文件。 我试图使用各种方式使其工作。 尽管可以成功显示该邮件已发送，但实际上并未发送。

          <?php 
             $errors = '';
             $myemail = 'abc@gmail.com';//<-----Put Your email address here.
               if(empty($_POST['name'])  || 
                    empty($_POST['email']) || 
                    empty($_POST['message']))
                             {
                      $errors .= "\n Error: all fields are required";
                            }
                      $name = $_POST['name']; 
                      $email_address = $_POST['email']; 
                       $message = $_POST['message']; 

                      if (!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0- 
                         9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", 
                            $email_address))
                          {
                          $errors .= "\n Error: Invalid email address";
                           }

                          if( empty($errors))
                           {
                            $to = $myemail; 
                            $email_subject = "Contact form submission: 
                            $name";
                            $email_body = "You have received a new message. 
                              ".
                            " Here are the details:\n Name: $name \n Email: 
                             $email_address \n Message \n $message"; 

                              $headers = "From: $myemail\n"; 
                             $headers .= "Reply-To: $email_address";

                    $result = mail($to,$email_subject,$email_body,$headers);
                    if(isset($result)){
                    echo "Sent Mail";

             }
             else{
                 echo 'mail cant be sent';
                 var_dump($result);
             }



                  } 


                ?>
