Demonstrates how to specify NTLM authentication for sending email via SMTP. C++

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    CkMailMan mailman;

    //  Specify your particular mail server's SMTP settings.
    mailman.put_SmtpHost("smtp.my_mail_server.com");
    mailman.put_SmtpPort(587);
    mailman.put_StartTLS(true);

    //  This assumes you know your SMTP server supports NTLM authentication.
    //  To explicitly request NTLM authentication, set the SmtpAuthMethod property = "ntlm".
    mailman.put_SmtpAuthMethod("ntlm");

    //  Note: Normally you should avoid setting the SmtpAuthMethod.
    //  SMTP servers tell the connecting client the authentication methods it will accept when the initial connection is made.
    //  Chilkat will automatically use this information to select and use the most secure auth method supported by the server.
