Add options to send mixed encrypted/unencrypted message when one of receipients is removed from domino directory

A user received a Notes encrypted email with several recipients before. One of the recipients was being removed from the Domino Directory which may due to employment termination. Other recipient then performed “Reply ALL” for this notes encrypted message using Verse for Mobile app.

User will received a failure message like:
Traveler - Encryption Failed. Your mail with subject "xxx" sent from your device was not delivered. This message has been saved to your drafts folder. The failure(s) are:
No public encryption key was found in the Domino directory for <user's>.

User can't send this message out. So customer hope:

Allow an option to ignore the failures and send anyway (mix of encrypted/unencrypted) . Send encrypted message to valid address(has public encryption key), unencrupted message to invalid address(no public encryption key).
