Hi,

after migrating to 2.2 (currently using 2.2.5), I see strange error messages when using imapc + public namespace + acl

My setup: I create a public shared mailbox with imapc as location. Then I restrict this mailbox to one user only using ACLs.

This works for this one special user, but for all others an error gets logged and they can't access their mailbox anymore:

Sep 24 18:09:46 [dovecot] imap(other@my.domain): Error: user other@my.domain: Initialization failed: Namespace 'Gemeinsam.': Ambiguous mail location setting, don't know what to do with it: yes (try prefixing it with mbox: or maildir:)

                            Sep 24 18:09:46 [dovecot]

imap(other@my.domain): Error: Invalid user settings. Refer to server log for more information.

My config (relevant parts):

------------------ Dovecot conf ----------------

imapc_host = some_host imapc_port = 143 imapc_user = some_user imapc_password = some3$pwd imapc_ssl = starttls imapc_ssl_verify = no

namespace gemeinsam { type = public separator = . location = imapc: prefix = Gemeinsam. subscriptions = no }

# I also tried different combinations of hidden and list

plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 }

------------- /etc/dovecot/global-acls/Gemeinsam -------

anyone user=special@my.domain lrwstipekxa

Does anyone have any thoughts about this?

Thanks, René
