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

    //  The mailman object is used for sending and receiving email.
    CkMailMan mailman;

    //  Set the SMTP server (obviously, use your SMTP server, not chilkatsoft.com)
    mailman.put_SmtpHost("smtp.chilkatsoft.com");

    //  Set the SMTP login/password (if required)
    mailman.put_SmtpUsername("myUsername");
    mailman.put_SmtpPassword("myPassword");

    //  Create a new email object
    CkEmail email;

    email.put_Subject("This is a test");
    email.put_Body("This is a test");
    email.put_From("Chilkat Support <support@chilkatsoft.com>");
    success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com");
    //  To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

    //  To send high-priority email, 
    //  add the X-Priority header field with the value "1" 
    //  to indicate highest-priority.
    //  A value of "3" is normal, which is the same as not setting
    //  the X-Priority header at all, and "5" is the lowest. 
    //  "2" and "4" are in-betweens.

    //  Microsoft Outlook might add the following headers when
    //  sending high-priority email.

    //  X-Priority: 1 (Highest) 
    //  X-MSMail-Priority: High 
    //  Importance: High 

    //  The X-Priority header alone is enough to make the email high-priority.

    email.AddHeaderField("X-Priority","1");

    //  Call SendEmail to connect to the SMTP server and send.
    //  The connection (i.e. session) to the SMTP server remains
    //  open so that subsequent SendEmail calls may use the
    //  same connection.  
    success = mailman.SendEmail(email);
