Organizers E-Mail Address when sending invitation...

[Kubernetes]

When I invite another User to an appointment he receive the invitation by e-mail. But the senders "E-Mail address" is just the login Name from Cloudron in Radicale, but not a valid E-Mail address. So if the receiver accepts or declines the inivtation, he will get a Bounce, because the Organizers E-Mailaddress is invalid.

Anybody an idea how to fix that?

Example of an ICal file:

I decided to switch for this functionality over to SoGo.

The radicale ldap plugin only does authentication. So, in fact, there is no way for radicale to know about any CN. I suspect this is being generated by something else (afaik, the client generates the events file). In my testing, organizer looks like below:

ORGANIZER;PARTSTAT=NEEDS-ACTION;ROLE=REQ-PARTICIPANT:mailto:girish@cloudron
