Answer 1

NTLM 身份验证在当前版本的 MailKit 1.6.0 中不起作用（嗯，它适用于一些服务器，但显然不适用于其他服务器）。

根据 https://github.com/jstedfast/MailKit/issues/397，我最近提交的一个补丁理论上会解决这个问题，但我没有收到提交错误的人的回复以确认它有效。

您可以从 GitHub 下载的源代码进行编译，也可以等待下一个版本。

同时，您可以像这样禁用 NTLM 身份验证：

client.AuthenticationMechanisms.Remove ("NTLM");

在调用 Authenticate() 之前进行此调用。
