PHPMailer突然发送失败
PHPMailer突然发送失败
提问于 2021-10-28 09:03:59
我只想问一下有没有解决这个问题的办法。我的phpmailer设置工作正常，直到一周前发送失败。
下面是我的phpmailer配置
$mail = new PHPMailer(true);
$mail->CharSet = "UTF-8";
$mail->isSMTP(); // Set mailer to use SMTP
$mail->SMTPDebug = 4; // Enable verbose debug output
$mail->Host = "smtp.office365.com"; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->SMTPKeepAlive = true; // SMTP connection will not close after each email sent, reduces SMTP overhead
$mail->Username = "email@email.com"; // SMTP username
$mail->Password = "secret"; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, ssl also accepted
$mail->Port = 587; // TCP port to connect to
$mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);这是调试输出：

最近出现了一系列与Outlook相关的问题-我怀疑他们已经不再支持一些旧的TLS版本，而只支持这些旧协议的旧PHP配置将停止工作。我认为他们正在缓慢地在他们的许多服务器上推出这种变化，所以这将是间歇性的，但会越来越频繁地发生。
解决方案是更新您的PHP版本。
