Async Upload (Append) Email to an IMAP Mailbox

Use the AppendMailAsync method call to append an email to an IMAP mailbox. Go

    success := false

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

    imap := chilkat.NewImap()

    // Connect to an IMAP server.
    // Use TLS
    imap.SetSsl(true)
    imap.SetPort(993)
    success = imap.Connect("MY-IMAP-DOMAIN")
    if success != true {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    // Login
    success = imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
    if success != true {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    // Create a simple email with 2 recipients.
    email := chilkat.NewEmail()
    email.SetFrom("support@chilkatsoft.com")
    email.AddTo("Chilkat Sales","sales@chilkatsoft.com")
    email.AddTo("Chilkat GMail","chilkat.support@gmail.com")
    email.SetBody("This is a test email.")
    email.SetSubject("This is a test email.")

    // Imagine we've sent this email via SMTP, and now we want to 
    // save the email to our "Sent" mailbox.  On GMail, the mailbox name
    // for sent email is "[Gmail]/Sent Mail".

    // Call the async version of the AppendMail method to return a task object.
    c := make(chan *chilkat.Task)
    go imap.AppendMailAsync("[Gmail]/Sent Mail",email,c)
    task := <-c
    if imap.LastMethodSuccess() != true {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        email.DisposeEmail()
        task.DisposeTask()
        return
    }

    // Schedule the task for running on the thread pool.  This changes the task's state
    // from Inert to Live.  The task is now running...

    if success != true {
        fmt.Println(task.LastErrorText())
        task.DisposeTask()
        imap.DisposeImap()
        email.DisposeEmail()
        task.DisposeTask()
        return
    }

    // -------------------------------------------------------------------------------
    // The following is a general note that applies to all programming languages:
    // -------------------------------------------------------------------------------
    // Your application can keep a reference to the task object and periodically check back later to see if it's finished.
    // If your programming language is one that supports callbacks, then the TaskCompleted callback can
    // be setup to be called when the task completes.  (See the "Async" category on example-code.com for more information.)
    // 
    // NOTE: This is very important:  A TaskCompleted callback runs in the background thread.  
    // (All callbacks from an async task, such as AbortCheck, PercentDone, ProgressInfo, etc. are in the background thread.) 
    // An application that uses TaskCompleted must be very careful.  
    // For example, user interface elements (such as labels, text boxes, etc.) may not be directly
    // accessible from a background thread, and could crash the application if directly accessed.  Also, attempting to debug
    // code running in a background thread from an IDE, especially an older IDE (such as VB6) is likely to crash the IDE.
