Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/'

12 Aug 2014


      Hello List,
with dovecot version 2.2.13.9, I actually have a problem using
lazy_expunge and acl together.
Shared/Public Folders work fine with lazy_expunge disabled.
If lazy_expunge is enabled and userA got a shared folder form userB,
then there is the error shown in subject.
My test case to reproduce the error.
doveadm mailbox list -u userA@domain
--> Output Fine.
doveadm acl set -u userB@domain INBOX user=userA@domain lookup read
write write-seen write-deleted insert expunge create
--> Fine.
doveadm mailbox list -u userA@domain
--> Some output and then:
--> doveadm(userA@domain): Fatal: lazy_expunge: Unknown namespace:
'.EXPUNGED/'
I think this is a bug in dovecot, can someone of the dovecot developers
or someone else confirm this?
If it is not please show me the fault in my configuration.
In May 2014 there was a thread with the same issue on this mailing list,
but with no solution.
