The presence of this character string in the Subject field would indicate that the sender was requiring that this message be sent via TLS or not at all. As a result, if the email could be sent via Forced (Mandatory) TLS, the email submission would complete in the usual manner. However, if the attempted TLS connection was not successful, the email would be redirected to the sender with an indication that the secure TLS email transmission was not successful.
You can do this with existing facilities. No development needed.
