We would like to be able to create Signatures that are branded and define Colors
We actually are required to respect Color Branding since we are a Governmental Service and i bet a lot of Zammad users would also benefit from that
Here is an example as what a signature could look like
This has historically been requested in a GitHub issue. we don’t want to embed as image since Email clients tend to remove/hide images
Colors are filtered intentinally for security reasons, which is why you can’t use them at the moment.
A solution of your problem would be, to add signatures on all outgoing mails not via Zammad, but your Mail-Server.
At least that would be a fast working solution for you.
