Please add the ability to use a wildcard SMIME certificate for all user accounts (Server side decryption of incoming and Signing of outgoing)
Thank you for your feedback. Adding SMIME support will be considered for future versions.

Is comming up usually in Spain that different departments of the government required mails signed with this personal certificate.
Client programs as "thunderbird" and "MSoutlook" can do it but if you work with web-email as worldclient this is not possible.
Yes, its a encryption that is supported by many Mail Clients (from costumers and other company)
