php電子郵件功能不能使用.org電子郵件

Question

因此，我試圖發送一封電子郵件，通知辦公室管理員通過表單提交電子郵件的時間。一切都沒有問題，工作時，我曾在「.COM」結尾的郵件然而，當我嘗試使用「.ORG」結尾的郵件

$first_name = $_POST['first_name']; 
$last_name = $_POST['last_name']; 
$email_address = $_POST['email_address']; 
$message = $_POST['message']; 

if(isset($_POST['submit'])){ 
$to = "officeadmin@example.org"; // Office Admin Email 
$from = $email_address; // User's Email 
$subject = "Form Submission"; 

$content_admin = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $message; 
$content_user = "Thanks again for contacting us. A dedicated staff member will contact you as soon as possible. Your message was: \n\n" . $message; 

$headers_admin = "From:" . $from; 
$headers_user = "From: Example Office"; 

mail($to,$subject,$content_admin,$headers_admin); //Notification email for admin 
mail($from,'Thanks for contacting us',$content_user, $headers_user); //Copy of email sent to user 

header('Location: contact_form_success.html'); //Redirect here after submit is clicked 
}

基本mail()功能沒有得到很好的配置所以有時可能出現問題，所以你

嘗試PHPMailer，它是配置良好的PHP郵件類發送郵件。
