I promote encryption in my union, association and workplace. Currently, not every computer run linux, and some still run windows.
However, I succeed in making everyone use thunderbird; I try now to make every email encrypted. It work pretty well until I try to encrypt a shared address (let say “contact@org”) :
The RSA key work well on thunderbird on linux, but fail to decrypt email on thunderbird on windows.
What am I missing ? Thunderbird seems to support ECC encryption; is it more suited ?


I’m referring to discovery, not search for end-users.
Most countries have regulations for companies to retain all internal communications for discovery purposes in the event that they are involved in a lawsuit.
