doveadm expunge returns error code 68

Hi, i am running basically this from cron:

/usr/bin/doveadm -v expunge -u * mailbox INBOX.Spam SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Trash SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Junk SENTBEFORE 90d

Now i am experiencing that the first line e.g. expunging INBOX.Spam returns the error code 68. No syslog/Output whatsoever. I tried running with -vvv -D which gives me a lot of output (for all mailboxes) but still i am unable to pinpoint the problem. The later 2 commands return "0" as expected.

Where does the error return code come from and what does 68 mean?
