Not really:

% doveadm search -u mailinglists at xgm.de mailbox INBOX  SAVEDSINCE 2013-11-21

doveadm(mailinglists at xgm.de): Error: user mailinglists at xgm.de: Initialization 
failed: Namespace '': Mail storage autodetection failed with 
home=/home/flindner/Mail/mailinglists at xgm.de
doveadm(mailinglists at xgm.de): Fatal: User init failed

Which seems to be another problem. IMAP and POP3 work fine, but on occasions 
like that dovecot fails to detect that it is a maildir.

Problem may be that in my database home and mail location is identical (and 
there is no way to change that). Is there a way to tell dovecot that every 
mailbox is a maildir without modifying the database?

Thanks,
Florian
