I think in S/MIME exist different types of certificates as I own one for signing but that can't be used for encryption. Not sure how this is handled. What is strange is this: I received an email where MM stated that it was successfully S/MIME decrypted. But I don't have any S/MIME encrypting certificate. So I'm wondering why MM displays this message. Further I don't have a clue how the one who send me the email would have gained access to my S/MIME certificates. > I think this happens automatically in Apple Mail.
