PHPMailer服务器->客户端：550 5.7.1无法中继

我无法使用phpmailer和microsoft exchange发送邮件

这是我的密码：

$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = 'mail.myhost.com';
$mail->SMTPDebug  = 2;
$mail->Username   = "myUsername";
$mail->Password   = "myPassword";
$mail->From = "from@server.com";
$mail->AddAddress("some.address@gmail.com");
$mail->Subject = "Test";
$mail->Body = 'Test';
$mail->send();

我得到这个信息：

我的发件人和收件人地址不见了

有人知道问题出在哪里吗？

首先，我建议你将其变为现实

对于from字段，将其插入括号之间，并更改setFrom中的参数

看看这个：不确定，如果是问题。Thx，我认为是问题，我明天再看

$mail = new PHPMailer(true);

$mail->setFrom = ("from@server.com");
