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.
