Hi…I would want to know like making in order to eventually add to an electronic sign(and cryttograf.) to the messages notes that they come sendes to you towards Internet customers (and that therefore they read the messages with outlook) for being able to guarantee that the message has been effectively sent from a Server
of a specific company. (the server that sign the email).
The sign is possible to generate from internal certificate or from external CA?
How can i get a valid PKCS12 (or PFX or P12) to use with notes?
Many thanks.
