NTLM on Pop3 client

Hello,
I have a developer OEM subscription for Aspose.Email
My application uses aspose pop3 client to connect to exchange and download email
Now, i need to configure it on a scenario, where (i suppose) exchange is configured to NTLM.
If i try with thunderbird or other, i set "NTLM" in the "authentication method" dropdown, and it works.

How should i configure the aspose pop3 client?

Thanks

Best regards,
Andrea
