We are generally encrypting our e-mails with S/MIME. Currently, we are using Horde, when we need a webmail component. We are considering a migration from Horde to Nextcloud, but we would need a webmail app with S/MIME support in it.
Since Nextcloud’s Mail app is based on Horde libraries, I’d hope that it’s not too difficult to add S/MIME support there.
Are there any such plans?
