Question

当我尝试在Windows server 2012上使用PHPMailer使用SMTP发送报告电子邮件时，我收到了身份验证失败的错误。

我在域上使用服务器管理员帐户。

我非常确定密码更正。

检查以下代码：

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);

我得到了以下回复：

Answer 1

通过更改$ mail-＆gt; SMTPAuth = true解决问题;为假。

$ mail-＆gt; SMTPAuth = False;

Answer 2

如果您使用的是来自 GoDaddy 的 Office 365 并且启用了 2FA，请按照 these 步骤禁用 2FA。这解决了我的问题，即使 SMTPAuth 为 true 也能正常工作。
