Yes, it fails because the Domino server has been setup to not accept SMTP relays from unknown sources (to avoid spam).
是的，它失败是因为 Domino 服务器已设置为不接受来自未知来源的 SMTP 中继（以避免垃圾邮件）。
Contact the admin of the Domino server so that you can set up Domino to accept relay from machines running your application (if they can be uniquely identified), or from internal hosts (if that's the case), and/or combined with a SMTP account to login to SMTP.
联系 Domino 服务器的管理员，以便您可以将 Domino 设置为接受来自运行您的应用程序的机器（如果它们可以被唯一标识）或来自内部主机（如果是这种情况）和/或与 SMTP 帐户组合的中继登录到 SMTP。
