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

    //  Demonstrates how to get the successful recipients for the last email sent.

    //  Note: Success does not ensure actual delivery, nor does it mean the email address is actually valid.
    //  It may be that the email address is invalid and will get bounced at the destination.

    //  Also: An SMTP client (such as Chilkat, Mozilla Thunderbird, etc.) is only responsible for "handing off" the email to the SMTP server 
    //  for delivery (either to a local mailbox, or to a remote mailbox where the SMTP server acts as a relay). 
    //  The SMTP client's task is ended when the SMTP protocol exchange is completed, and the SMTP server says "OK, I've got it and I'll take it from here.". 
    //  If the email never actually gets delivered, then there is a problem downstream of the Chilkat-->SMTP server handoff.
