    let mailman = CkoMailMan()!

    // Specify your particular mail server's SMTP settings.
    mailman.smtpHost = "smtp.my_mail_server.com"
    mailman.smtpPort = 587
    mailman.startTLS = true

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