For most messages, sending the outgoing email by Opportunistic TLS would be
desirable and perfect.
However, if the Subject field contains "[Secure]", I would like that to trigger
different message handling by EXIM. 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.
