Hi, I'm using S/MIME to sign/encrypt my emails. The current certificate has now expired, so I got a new one.
1. How does MM handle old emails sent to me? Are those decrypted on receive and then stored unencrypted? Does MM need to have access to the expired certificate?
2. How does MM select the appropriate certificate? Do I have to delete the old one? Does MM only search for a valid one?
Viele Grüsse
