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

    // Starting May 30, 2022, Google will no longer support the use of third-party apps or devices 
    // which ask you to sign in to your Google Account using only your username and password.

    // Instead of authenticating with your GMail username/password, a GMail user can create an App Password
    // and then login using their username/app_password.   It's literally the same, except it allows a GMail
    // account owner to isolate passwords to specific applications.

    // The Gmail account owner would first need to make sure she has 2-Step Verification setup for her account.
    // Note: The 2FA verification is not a factor when authenticating with an app password. The 2FA is required
    // to setup app passwords in the Google account console.  See Sign in with App Passwords

    // After the GMail account owner has setup his app password, he simply uses the app password instead of his GMail account password.

    // For example:
    imap := chilkat.NewImap()

    imap.SetSsl(true)
    imap.SetPort(993)

    success := imap.Connect("imap.gmail.com")
    if success == false {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    success = imap.Login("user@gmail.com","srnyyvqajocnsvdp")
    if success == false {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    fmt.Println("IMAP Success!")

    // For SMTP..

    mailman := chilkat.NewMailMan()

    mailman.SetSmtpHost("smtp.gmail.com")

    mailman.SetSmtpUsername("user@gmail.com")
    mailman.SetSmtpPassword("srnyyvqajocnsvdp")

    mailman.SetSmtpSsl(true)
    mailman.SetSmtpPort(465)

    success = mailman.SmtpConnect()
    if success == false {
        fmt.Println(mailman.LastErrorText())
        imap.DisposeImap()
        mailman.DisposeMailMan()
        return
    }

    success = mailman.SmtpAuthenticate()
    if success == false {
        fmt.Println(mailman.LastErrorText())
        imap.DisposeImap()
        mailman.DisposeMailMan()
        return
    }

    fmt.Println("SMTP Success!")

    imap.DisposeImap()
