My mailboxes.db seems to be corrupted.
Two things happened at about the same time, and I'm not clear which one broke things.
While trying to debug an issue I ran `ctl_cyrusdb -r`. Also, Cyrus was upgrade from 3.2.6 to 3.6.1. Also,
The result was /var/spool/cyrus was empty, and mailboxes.db had some defaults for the two users on the system, but nothing else.
I have full backups of /var/spool/cyrus, so that's no problem, I restored that... but I don't have a backup of mailboxes.db (/var/lib/cyrus has been added to the backup list now, sigh). The system itself seemed two have two backups, but `ctl_mboxlist -d -f db.backup1/mailboxes.db` and `ctl_mboxlist -d -f db.backup2/mailboxes.db` both show just the default folders.
I have all my mail, but cyrus imapd can't seem to serve it up. Is there a way to reconstruct mailboxes.db from /var/spool/cyrus/mail ?
Thanks!
