i am testing the S/Mime Plugin but i do not arrive in importing public certificates of (foreign) E-Mail partners.
I have successfully imported the CA-Certificate that was used to issue the (public) certificates of our partner organization.
The only way i have found to import an foreign public certificate, is to have the foreign E-Mail partner to send a signed E-Mail. This is not always possible for us, because our users need to encrypt every E-Mail to a partner organisation, also the first one, for legal reasons. Also the employees of the partner organization often don't know what we are talking about if we try to get a signed E-Mail from them. :-(
How can a WebApp User (or alternatively the admin) import an PublicKey of someone without needing the help of that someone?
Thanks for any help ....
