Dear all,
we're running a Cyrus Murder with 6 backend servers, two frontend
servers and one MUPDATE master. All servers are compiled from vanilla
source 2.4.17 and run on Debian Wheezy. Delayed delete / expunge is
activated:
expunge_mode: delayed
delete_mode: delayed
This works fine so far. Several of our users however use Open-Xchange
(version 7.2.2) with IMAP as their mail client. When these users delete
a mailbox, Open-Xchange will copy the mails from that mailbox to a new
folder within the trash folder and delete the mailbox afterwards. Cyrus
then reports the mailbox was deleted:
Sep 23 10:18:25 s_local@cyrus-be5 cyrus/imap[29267]: Rename:
user.foobar.Test -> DELETED.user.foobar.Test.523FF951
Sep 23 10:18:25 s_local@cyrus-be5 cyrus/imap[29267]: Deleted mailbox
user.foobar.Test
But still the mailbox is left behind in the filesystem
(/var/spool/cyrus-imapd/f/user/foobar/Test/ in our case) with all mails
and cyrus.* files. It is however removed from the mailbox database.
This was not the behavior we expected. We expected that delayed_delete
would move the mailbox to DELETED namespace, thus deleting the original
folder. Instead we see that a copy is created under DELETED.
I suspect this is somehow the fault of Open-Xchange since other clients
like Thunderbird 24 don't cause this issue. Or might this be a
configuration error on our side? We tried setting "delete_mode:
immediate", but the original mailbox was still left behind.
Here is a IMAP trace when deleting the mentioned mailbox with
Open-Xchange with "delete_mode: delayed".

Right now we use a cron job to detect these cases and decide manually if
we want to delete the remaining directories or not. If you need more
information / traces / etc., we would be happy to provide them.
Thanks for your time and effort!
Best Regards,
Peter
