There are some other questions to solve:
- Should this be public available or Djigzo/Sign-in only?
I think it should be publicly available.
- It should only allow full e-mail address direct
matching, no wildcards
etc. to prevent address harvesting
Yes, protecting email addresses is important.
But beside this it would solve one of the biggest S/MIME problems today.
It would be somewhat similar to the mentioned www.bridge-ca.org
without paied membership?
Our view is that email encryption can only be a success when it becomes
a commodity so I think that such feature should be freely accessible.
Would be nice to have, no question. If it is possible for you guys to
cover the costs with a freely available service this is for sure a
must have ;-)
