Hi Sven,
Are you able to provide a sample mailboxes.db entry (using cyr_dbtool as Bron describes below) for a mailbox which is affected by this?
I'm trying to determine if the cause is bad data getting into the database, or good data that's being misread for some reason. An example would help a lot!
Cheers,
ellie

You'll have to run it as the cyrus user. You can use "show" to dump the whole file and grep for the individual mailbox, or "get" on the mailbox key directly to get the one line. Then "set" to set it with a value with that group name removed.You'll probably want to do another setacl on that mailbox with something safe afterwards, just so the cyrus.header file gets cleaned up as well. It contains a value which is a cache of the value in mailboxes.db.Cheers,Bron.On Tue, May 29, 2018, at 07:55, Bron Gondwana wrote:If you use cyr_dbtool you can edit the offending line in mailboxes db.Clearly there's a bug here too, we should be sanitising group names!
