Kopano WebApp S/MIME: certificate questions


I have some questions abot the S/MIME plugin:

  • Is it possible to keep outdated certificates in the store? For me, it seems, that only one certificate (+ private one for own address) can be stored.
    But how can I read older mails, signed/crypted with outdatet certificate?
  • OCSP: As far as I can see, the issuer certificate is taken from “CA Issuers - URI”.
    I am getting quite a lot of mails from a big company, which has “OCSP - URI” set, but no “CA Issuers - URI” in their certificates. Any chance, to retrieve the issuer certificate from the cert chain?


Hi Vogi,

The OSCP issue is described here: https://jira.kopano.io/browse/KSP-119
The other one here: https://jira.kopano.io/browse/KSP-23


Hi marty,

thanks for the information.
So there is a good chance, that these points will be improved in future versions.
