I have been using Apple Mail and S/MIME for quite a while now. While I have been starting with a commercial certificate, I now decided to switch to a certificate from a dedicated CA (recognized by all people to whom I correspond).
Both certificates are in my keychain, both have been issued for my email address, are valid and trusted.
Apple mail keeps using the certificate that has been in the keychain first.
Does anybody know a way to make Apple mail using the other cert? I don't want to revoke trust from the first cert as I still need it for decryption.
Thanks in advance!
