https://github.com/cyrusimap/cyrus-imapd/issues/2378 to track the issue.
Sorry about the short comment earlier on my phone as I woke up - meant
to save it as a draft and add some detail!
Usage: /usr/cyrus/bin/cyr_dbtool [-C altconfig] <db file> <db backend> <action> [<key>] [<value>]Usable Backends: flat, skiplist, quotalegacy, twoskip
* show [<prefix>]
* get <key>
* set <key> <value>
* delete <key>
* dump - internal format dump
* consistent - check consistency
* repack - repack/checkpoint the DB (if supported)
* damage - start a commit then die during
* batch - read from stdin and execute commands
You may omit key or key/value and specify one per line on stdin
keys are terminated by tab or newline, values are terminated by newline
<db file> will need to be your mailboxes.db (e.g. /var/imap/mailboxes.db
on many systems). 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.
