[Dovecot] Dovecot2 and mdbox problem

[Michael Grosseck]

Hello,

I've just installed Dovecot from the http://xi.rename-it.nl/debian/ 
repository. But I have a problem with the mdbox Format.
When the home folder is empty Dovecot should  create the folder 
structure if the first mail arrived or the user logs in the first time.
But I get following error:
Sep 16 12:30:41 smtp dovecot: lmtp(31244): Connect from local
Sep 16 12:30:41 smtp dovecot: lmtp(31244, info at example.de): Error: 
file_dotlock_open() failed with file 
/var/mail/es030107p1/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log: 
No such file or directory

Sep 16 12:30:41 smtp dovecot: lmtp(31244): Disconnect from local: Client

Also if I try to create a mailbox by hand I get a similar error.
doveadm(info at example.de): Error: file_dotlock_open() failed with file 
/var/mail/es030107p1/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log: 
No such file or directory
doveadm(info at example.de): Error: Can't create mailbox INBOX: Internal 
error occurred. Refer to server log for more information. [2010-09-16

If I now create the dbox-Mails directory and the dovecot.index.log by 
hand and make a
doveadm -v force-resync -u info at example.de INBOX
everthing is alright.

Also I can not create a new IMAP-folder with Thunderbird.
It seems Dovecot forgets to create the dbox-Mails directory and the 
dovecot.index.log file.

Now my config:
