Ensure that Zammad is on the latest available stable (6.5.2 is current) and if the issue still exists create a bug report on Github.

I think the problem is with the font. How can I change the default font in sent emails if I’m using a Docker Compose installation? I couldn’t find a way to set the variable via Settings.set() in my case.

My sollution:

docker exec zammad-zammad-railsserver-1   
/docker-entrypoint.sh rails r   
‘Setting.set(“html\_email\_css\_font”, “font-family: Arial, Helvetica, sans-serif; font-size: 13px;”)’
