With this rpm, you should usually find backups of your mailboxes.db

in /var/lib/imap/backup/. If you don't have them, for any reason,

you can recreate it like this.

Note: The scripts doesn't care with different hashing schemes of

the mailspool. Adjust as needed!

And please, check the permissions mailboxes.db after creating it.

#!/bin/sh

#

# stop cyrus-imapd

service cyrus-imapd stop

# backup existing mailboxes.db

mv /var/lib/imap/mailboxes.db /var/lib/imap/mailboxes.db.$$

find /var/spool/imap/?/user -maxdepth 1 -mindepth 1 | \

  while read i; do

    echo $(basename $i)

    echo "user.$i<\t>default<\t>$i<\t>lrswipcda<\t>cyrus<\t>lrswipcda" >> /tmp/newmboxlist.txt

  done

# we have everyone's base directory in /tmp/newmboxlist.txt, now we

# import the new list

/usr/lib/cyrus-imapd/ctl_mboxlist -u 

# and reconstruct to get subfolders into the list

find /var/spool/imap/?/user -maxdepth 1 -mindepth 1 | \

  while read i; do

    /usr/lib/cyrus-imapd/reconstruct -rf user.$i

  done
