See that next Info line:

!!!!
Home directory not set for user. Can't expand ~/ for mail root dir
in: ~/
!!!!

In contrast to rechnungseingang-finanzbuchhaltung your userdb does not 
return no home dir for rechnungseingang-animationsinstitut, therefore your 
mail_location ~/ expands to the root directory "/".

You have to correct your userdb. Maybe you need to clean the cache:

doveadm auth cache flush
