IMAP STARTTLS (Explicit TLS/SSL)

The StartTls property is set to force the Connect method to automatically convert an connection to TLS/SSL via the STARTTLS IMAP command.

This is also known as "explicit TLS/SSL" as opposed to "implicit TLS/SSL". With implicit TLS/SSL, the IMAP client connects on the well-known IMAP TLS/SSL port 993 and the secure channel is immediately established. With explicit TLS/SSL, the IMAP client connects on the typical non-secure port (143 usually) and the converts the connection via the STARTTLS command.

Go

    success := false

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

    imap := chilkat.NewImap()

    // Indicate that STARTTLS should be used to convert
    // to a secure TLS/SSL connection:
    imap.SetStartTls(true)
    imap.SetPort(143)

    // Connect to an IMAP server and convert the connection
    // to TLS/SSL via STARTTLS.
    success = imap.Connect("imap.example.com")
    if success == false {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    // The remainder of this example is the same as for 
    // non-TLS/SSL...

    // Login
    success = imap.Login("myLogin","myPassword")
    if success == false {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return
    }

    // Select an IMAP mailbox
    success = imap.SelectMailbox("Inbox")
    if success == false {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        return

    fetchUids := true
