PHP Mailer发送电子邮件

Question

我在发送包含phpmailer的电子邮件时遇到问题。我对SMTP用户名和密码是什么感到困惑？那必须是myn吗？我创建了一个脚本，但它没有按预期工作。

我的页面一直在说

“无法发送消息.Mailer错误：SMTP连接（）失败。”

这是我的代码：

<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'jswan';                            // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also     accepted

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('josh@example.net', 'Josh Adams');  // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) 
{
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
   exit;
}

echo 'Message has been sent';
