I'm using Apple Mail and S/MIME to encrypt my e-mails. If there is a certificate for an e-mail address I want to send an e-mail to, everything is fine. After inserting the e-mail address, Mail enables the blue lock and the e-mail is sent encrypted. My problem is now: If I want to send an encrypted mail to a person whose certificate I have but this certificate is issued to an alias of the e-mail address the lock won't be enabled because mail does not find a certificate for that address.
I have a (public) certificate installed for
I want to send an e-mail to
email@example.com encrypted with the certificate of
firstname.lastname@example.org because the two addresses are aliases.
Nevertheless, Mail cannot encrypt the e-mail because it doesn't find a certificate for that address.
Is there any way to configure Mail that for encrypting e-mails to
email@example.com the certificate of
firstname.lastname@example.org has to be used?
