具有Gmail帐户的boostrap上的联系表单不会发送电子邮件

Question

您好，我正在设置一个供个人使用的网页，并正在配置“联系人”表单。按下发送按钮似乎可以正常工作，但是邮件永远不会到达帐户

php似乎还不错，我想知道您是否能帮助我

<?php
// Check for empty fields
if(empty($_POST['name'])      ||
   empty($_POST['email'])     ||
   empty($_POST['phone'])     ||
   empty($_POST['message'])   ||
   !filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
   {
   echo "No arguments Provided!";
   return false;
   }
   
$name = strip_tags(htmlspecialchars($_POST['name']));
$email_address = strip_tags(htmlspecialchars($_POST['email']));
$phone = strip_tags(htmlspecialchars($_POST['phone']));
$message = strip_tags(htmlspecialchars($_POST['message']));
   
// Create the email and send the message
$to = 'pantufla.una@gmail.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "Contacto desde pagina web:  $name";
$email_body = "Email enviado desde la pagina web.\n\n"."Detalles:\n\nNombre: $name\n\nEmail: $email_address\n\nTelefono: $phone\n\nMensaje:\n$message";
$headers = "From: pantufla.una@gmail.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
$headers .= "Reply-To: $email_address";   
mail($to,$email_subject,$email_body,$headers);
return true;         
?>
