Kerberos Support to SmarterMail (Windows Server 2025/Windows 11 24H2)

Currently if you disable NTLM (deny in/out connections) SmarterMail's autodiscover doesn't work.
eMClient response is Invalid Authentication so eMClient will not recognize SmarterMail's features.

Due Windows 2025 and future Windows build changes microsoft is disabling NTLM.

So it would be best SmartMail to use Kerberos instead of NTLM to be Windows Server 2025 compatible.
