The main qmail file ~/.qmail-default does not exist

id:qmail-default-not-exists

The file ~/.qmail-default is the only qmail file neccessary for the standard mail setup on U7.

To be able to use the standard mail setup you need to recreate the file with the command:

[isabell@stardust ~]$ uberspace mail spamfolder enable
The spam folder is now enabled.
