我正在用下面的脚本检查这个。
$sender = '[email protected]';
$recipient = '[email protected]';
$subject = "php mail test";
$message = "php test message";
$headers = 'From:' . $sender;
if (mail($recipient, $subject, $message, $headers)) {
echo "Message accepted";
} else {
echo "Error: Message not accepted";
}
更新：当前的答案将无济于事，因为在 main.cf 文件中的一些配置更改后错误代码发生了变化。
