S/Mime behaves unexpected on replies where the ticket itself was already fully signed and encrypted

Infos:

  • Used Zammad version: 6.20
  • Used Zammad installation type: Helm
  • Operating system: Linux
  • Browser + version: Firefox 122.0.1 (64-Bit)

Expected behavior:

If you receive an encrypted S/MIME email (aka sender encrypted it and zammad successfully decrypted it) I would expect to have an option to reply in an encrypted fashion without a manual cert import just like Thunderbird provides as a function. The cert of the other side is reasonably verified via the crypto itself at that point.

Actual behavior:

The button is greyed out since the cert is not imported

Steps to reproduce the behavior:

  • Send an smime signed email to a user from zammad where the user/customer cert is not in the zammad system imported
  • Reply as the customer with smime encryption and signing
  • Try to reply from zammad to the customer’s encrypted reply

it seems like the same issue is with the pgp integration however it at least prompts you to do some action.

Hi @MTRNord. Zammad is no Thunderbird and we’re decided to not auto-import certificates at all.
