If that logo is bound to your domain, we will find it and add it to your instance.
This is part of our magical image services.
This has nothing to do with on premise or not.
Thx. The logo was configured within my on prem instance. Then I asked for a hosted instance using a completely different domain and the logo showed up there. I don’t know why and I think it is an error. But never mind…
As I said. Clearbit and images.zammad.com are “clever”.
Your website actually holds the logo in question. It’s a feature.
