(Swift 3,4,5...) Send Email and Put Copy in "Sent" Folder

This example demonstrates how to send an email, and then put a copy of it in the "Sent" mail folder. This is only possible if the "Sent" folder is located on the mail server and accessed via the IMAP protocol. The POP3 protocol can only access the Inbox on the mail server.

This does not work with "Sent", "Sent Items", or "Sent Messages" folders that are stored locally on your computer by an email client such as Outlook or Thunderbird. Chilkat has no ability to copy email to the local files managed by these email clients.

    // the connection is closed.  In these cases, it is necessary to
    // call CloseSmtpConnection for the mail to be  sent.  
    // Most SMTP servers send the email immediately, and it is 
    // not required to close the connection.  We'll close it here
    // for the example:

    // The mail has been sent.  Now save the email to the "Sent" folder
