I tried upgrading my mailcow instance from 2023-11a to latest 2024-07, and after the upgrade my email client gets connection refused.
I remember a while back there were a ton of issues reported on GitHub with the update that came after 2023-11a, and that’s why I never upgraded.
Now I wanted to give it a try, and surely my fear came true, as after the upgrade the mail server no longer works.
I can log in to the web interface, but when I log in to a mailbox in SoGo it says no mailbox connected or something like that.
Can anyone provide some guidance?
Thanks
