You are talking about a secure email _network_, where only "trusted"
people can send emails to members. (i.e: a private mailing list).
You are suggesting a trusted system like this, right? And your
argument is that non-trusteds (phishers) can't get in and send emails
- fine, it may be true (depending on membership verification process).
How does this list communicate with the outside world? Customers?
Banks? ...? Do they have to become "trusted" too ? On what basis ?
Email address? Certificate? Who manages all this trust? Whats the
change-over timeframe to get the world onto this system as opposed to
the current one ?
I'm still a little confused as to what you are suggesting the solution
(the pratical solution) is here... because setting up such a trusted
network just isn't possible (and has been tried before, hasn't it ?)
If your idea is just about having a way to trust specific peoples'
messages (certificates) then fine, it's a system that would work on a
positive basis (customer: "Yes, this is from my bank, because the
little padlock is there..!") but not on a negative basis (customer:
"Hmm, it says its from my bank, but there is no pad lock... I will
click it anyway ... those banks, always stuffing things up.").
Implemented with my idea[1] from a long time ago, however, it could be neat :)
But I still don't see your problem with Client-side certificates.
