No update of mailman-files virtual-mailman and transport-mailman
After deleting a Mailman-list in ISP-Config the files 'virtual-mailman' and 'transport-mailman' are not updated. The files still contain the deleted list. This causes an error when creating a list with the same name.
deleted list was called 'test' and new created list is also calles 'test', then there a two entries for list 'test'
