爲什麼我的郵件不發送，但我配置smtp？

Question

代碼：

<?php 
$to = "rock_tam@yahoo.com"; 
$subject = "Test mail"; 
$message = "Hello! This is a simple email message."; 
$from = "krishna.tam04@gmail.com"; 
$headers = "From:" . $from; 
mail($to,$subject,$message,$headers); 
echo "Mail Sent."; 
?> 

錯誤：

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\htdocs\mail.php on line 7 Mail Sent.

Answer 1

你的互聯網服務提供商使用SMTP服務器。
