2.2.12.12 (03196f188677): /etc/dovecot/dovecot.conf

20 May 2014

      Hi,
since migration to Dovecot 2.2 I have troubles with lazy_expunge as soon as
a user shares a folder. The user the folder is shared to cannot login
anymore, dovecot logs Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/'

When no folder is shared lazy_expunge is working fine, deleted mails are
moved to the expunged namespace and can be recovered without any problems.
Sharing folders works as long as I disable lazy_expunge.

I have used the config (with minor changes) with dovecot 2.0 for years
without any problem. Switching to dovecot 2.2.10 (atrps repository) or
2.2.12 (dovecot enterprise repo) lazy_expunge and acl do not work together
anymore.
Is it a bug, a known limitation or is something wrong with my config?
Any hints are welcome.
Thanks in advance,
Florian
