I don't claim to be an expert on user interfaces or in human understanding of tehnical protocols, but do you really think that an average user can make an informed decision on whether to use an option that requires secure channels for email delivery, but still allows for the email to be read at many placed along delivery route, while generating the bounce in case one of the channels can't be adequately secured?
This is my problem. I can see it being marketed as a 'way of sending secure email' rather than a 'way of getting more bounces than successful deliveries'.

It isn't going to make email totally 'secure' - but it will improve it so I can see the advantage of the idea. However, I worry that end users will just tick the box by default (who would choose to use the 'send insecure email' option?) and then the people who manage the servers will be deluged with problem reports about emails not being delivered.

At what level of 'secrecy' would you expect this to be used? For 'really top secret messages', you'd be daft to use this, as it's not totally secure. For 'my holiday photo messages' you'd be daft to use it, as they're not secret, and you'd really rather the message got through than caring that some CIA agent got to waste time looking at your picture of a mountain.
