Windows NTLM / Kerberos auth support?

[jlrouzies-mantu]

Hello,

I'm deploying this SmtpServer solution, and would really like it to support NTLM (and maybe Kerberos) authentication.

Is it already supported or any guidelines how to implement it?

My objective is to have it worked without an already Windows / Active Directory authenticated user needing to pass credentials (login / password), as it would be e.g. with IIS SMTP or Exchange server with Windows Auth.

Thank you
