I made a self-signed cert this way, but could not get mail to use it for sending mail. Mail instead would complain that my old expired cert was invalid because it was expired [1].
I deleted the certificate and then made one more directly by using the defaults (which are for an s/mime certificate), opened the certificate and said to trust the certificate for s/mime. [2] The second certificate didn't work, either. I think I'll give up for a while. Bill [1] Deleting the old certificate is not an option, because it would cause all emails using it to become unreadable. [2] This yielded a certificate with (from what I could see) the same properties as the longer method. > On Jan 14, 2020, at 13:03, Pen Helm <pen-...@earthlink.net> wrote: > > Looks like you can use the Keychain Access app to create your own S/MIME > keys.
