Hi,

I have a problem using the master password feature of dovecot.

I'm able to login with the password but then dovecot can't select the INBOX.

IMAP test:

• OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=SCRAM-SHA-1 AUTH=CRAM-MD5] ITronic Mail Store

a login user@itronic.at*admin password

a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE NOTIFY QUOTA ACL RIGHTS=texk] Logged in

a list "" "%"

• LIST (\HasNoChildren) "/" INBOX

a OK List completed (0.003 + 0.000 + 0.003 secs).

a select INBOX

a NO [SERVERBUG] Internal error occurred. Refer to server log for more information. [2017-12-28 12:32:41] (0.001 + 0.000 secs).

The log with mail debuging doesn't tell me much:

2017-12-28T12:24:47+01:00 mailstore1 dovecot: imap(user@itronic.at): Debug: INBOX: Mailbox opened because: SELECT 2017-12-28T12:24:47+01:00 mailstore1 dovecot: imap(user@itronic.at): Debug: acl vfile: file /srv/storage1/vmail/itronic/6/mdbox/mailboxes/INBOX/dbox-Mails/dovecot-acl not found 2017-12-28T12:24:47+01:00 mailstore1 dovecot: imap(user@itronic.at): Debug: acl vfile: file /srv/storage1/vmail/itronic/6/mdbox/mailboxes/dovecot-acl not found 2017-12-28T12:24:47+01:00 mailstore1 dovecot: imap(user@itronic.at): Debug: Namespace : Using permissions from /srv/storage1/vmail/itronic/6/mdbox: mode=0700 gid=default 2017-12-28T12:24:47+01:00 mailstore1 dovecot: imap(user@itronic.at): Error: Opening INBOX failed: Mailbox doesn't exist: INBOX

If I use the password of the user it works without problems, I also tested other users, they have the same problem.

I would be happy for any debugging help.
