Introduction

Horde - Imp is a web based mail program and is not an application that sits on your local hard-drive. Because of this we need each user to update the security certificate individually. We have put together a set of instructions which should assist in the process of updating your certificate.

When a CA certificate expires a new one has to be issued. In the case of it being a self-signed certificate, browsers that use it will need to have the new one added. There is currently no way to do this automatically, as there are decisions of trust that have to be made.
