PHPMailer 身份验证失败

Question

当我尝试在工作中的 windows 服务器 2012 上使用 PHPMailer 来使用 SMTP 发送报告电子邮件时，出现身份验证不成功错误。

我在域中使用服务器管理员帐户。

我非常确定密码的更正。

检查下面的代码：

require '../PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';
$mail->Host = 'mail.example.com';
$mail->Port = 25;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "username@example.com";
$mail->Password = "yourpassword";
$mail->setFrom('from@example.com', 'First Last');
$mail->addAddress('whoto@example.com', 'John Doe');
$mail->Subject = 'PHPMailer SMTP options test';
$mail->msgHTML($html_message);

我收到以下回复：

Answer 1

问题已通过更改 $mail->SMTPAuth = true 解决；为假。

$mail->SMTPAuth = False;

Answer 2

如果您使用的是 GoDaddy 的 Office 365 并且启用了 2FA，请按照 these 步骤来禁用 2FA。这解决了我的问题，即使 SMTPAuth 是 true.

它也能正常工作
