ARGH! indeed, the old cyrus-imapd packages appear to have a grave bug that
removes ALL the information without any futher questions asked on purge.
I don't know what we can do about this, though :( Those packages are gone
and only present in oldstable.

Look at /var/backups, cyrus21 packages do daily backups of the mailboxes
database there, file /var/backups/cyrus-mboxlist.txt.gz
It only keeps TWO backups, so go there fast before the cronjob kills it.
After using ctl_mboxlist to restore the mailboxes from that backup, use
cyrreconstruct to restore as much information as you can. Some will have
been lost, but the emails will all be there (I am not too sure about the
seen state, though. I think that one has been lost, it was in
/var/lib/cyrus).
