and continues processing the original message. Any additional actions apply 
to the original message. 
Encrypt on Delivery
The message continues to the next stage of processing. When all processing 
is complete, the message is encrypted and delivered.
Encryption rule: Always encrypts the message or only encrypts it if an 
attempt to send it over a TLS connection first fails. See
