I keep admin in dark and rspamd in light (for ease of readability).
Since upgrading to 2026-01 this theme arrangement is no longer maintained.
To reproduce; Set mailcow to light, then refresh rspamd, it should also be light theme. Set rspamd to dark, refresh mailcow ui, it should now be dark.
It appears to be impossible to get both to be different themes from the other.
Opened mailcow/mailcow-dockerized7083 few weeks ago.
