Cyrus-Imap messages deleted - how best to restore?
I'm running a cyrus-imap server - mostly for myself but some other logins can access it. It's a Fedora 13 package on an Intel server. I have all the mail in its own folder under /data; otherwise it's a pretty simple setup.
Just recently I was stupid and changed a setting in Thunderbird that caused lots of old email to be deleted that I didn't want to be deleted from the server (just locally...) Thunderbird was told to delete mail over 90 days old, so there's a fair bit still around.
I have regular backups of the data directory (via bacula) and occasional backups where I stop the server and do a backup 'offline'.
What I'm not sure of is how best to restore my mail (and not change anyone else's) while not deleting the latest mail (which of course won't be on a backup).
