使用php发送邮件的问题

Question

有人可以帮助我吗？ 我需要使用php发送电子邮件。

我正在使用此代码发送邮件

<?php

error_reporting(E_ALL); ini_set('display_errors', '1');
require '/PHPMailer-master/PHPMailerAutoload.php';
error_reporting(E_ALL); ini_set('display_errors', '1');
echo (extension_loaded('openssl')?'SSL loaded':'SSL not loaded')."\n"; 

$mail = new PHPMailer;

$mail->SMTPDebug = 2;                               // Enable verbose debug output

$mail->isSMTP();                                   // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;
$mail->SMTPDebug = true;                              // Enable SMTP authentication
$mail->Username = 'email@gmail.com';                 // SMTP username
$mail->Password = '******';                           // SMTP password


$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to

$mail->From = $_POST['email'];
$mail->FromName = 'Mailer';
$mail->addAddress('email@gmail.com', 'Joe User');     

$mail->IsHTML(false);                                  // Set email format to HTML

$message = $_POST['message'];
$mail->Subject = $_POST['subject'];
$mail->Body = preg_replace('/\[\]/','',$message);
$mail->AltBody = 'This is a plain-text message body';

if(!$mail->Send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}


?>

归来总是这样。

我正在使用PHPMailer。 我已经阅读了https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting，但没有任何变化。
