我试图配置后缀以使用Azure 虚拟机上托管的 centos 7 上的 phpmailer 发送 smtp 电子邮件。(防火墙/selinux 已禁用(
我的问题是当我尝试使用phpmailer时，我收到"客户端：503 5.5.1 错误：未启用身份验证 SMTP 错误"。

这是我的phpmailser邮件设置。

由于上述错误，我无法使用phpmailer，但我可以成功地远程登录到服务器中的端口25

请指导我解决问题。 谷歌搜索和故障排除几个小时，但没有线索。
大多数服务器不允许在没有加密的情况下进行身份验证，并且您尚未对其进行配置 - 服务器没有通告任何AUTH机制，因此PHPMailer只是尝试一下。
不允许在端口 25 上发送也是正常的，这就是 SMTP 提交协议存在的原因;在端口 587 上使用SMTPSecure = 'tls'提交，或在端口 465 上使用ssl提交。
或者，既然它是本地主机，为什么还要费心进行身份验证呢？试试$mail->SMTPAuth = false;
