dovecot - May 2019 - Userdb userdb_mail=, error Mailbox list driver maildir++: maildir_name not supported by this driver

I have this default configuration [0], when use the userdb_mail to point 
to the mdbox location, the inbox subfolders show differently in a 
firebird client. So I decided to copy the whole default mail_location 
into the userdb_mail configuration [2]. But then I get errors [3]. 
Should I change the namespace configuration here, how? My default 
namespaces are inbox and 4archives

Are you intentionally mixing mbox and mdbox? You see that [0] has mbox, and [2]
has mdbox.

Yes, I have still inbox mbox format because I have sendmail delivering 
there. I trying to migrate/convert 
 step by step, with least possible impact for users.
