Cyrus IMAP Mailbox Recovery

BOoRFGOnZ

Step 1: Backup the locally-cached mail
The file will be inside ~/Library/Mail/IMAP-email-address, with an extension ".imapmbox". Copy this file to your Desktop.
Step 2: Repairing the Cyrus folder

• Use Server Admin to stop the mail server
• Change to root, and enter the directory /var/imap:
  # sudo -s
  # cd /var/imap
• backup mailboxes.db:
  # cp mailboxes.db mailboxes.db-backup
• Using Workgroup Manager, set user cyrus's shell to bash
  (Ed. note: Rather than give cyrus a shell you could just use sudo -u cyrus to do the following steps.)
• su to cyrus, and dump the database to a text file:
  # su cyrus
  # /usr/bin/cyrus/bin/ctl_mboxlist -d > /tmp/mboxlist.txt
• Edit the text file and remove the lines that contain the problem folders:
  # pico /tmp/mboxlist.txt
• remove mailboxes.db:
  # rm mailboxes.db
• rebuild mailboxes.db from the new text file:
  # cat /tmp/mboxlist.txt | /usr/bin/cyrus/bin/ctl_mboxlist -u
• Reconstruct all mailboxes
  # /usr/bin/cyrus/bin/reconstruct -r -f userIf there are any remaining folders that print an error, they'llbe listed when performing cyrus reconstruct: (ie.. user.someuser:Mailbox does not exist).
• Exit back from cyrus and root
  # exit
  # exit
• Using Workgroup Manager, set user cyrus's shell back to /usr/bin/false.
• Restart Mail using Server Admin

Step Three: Recovering a locally-cached imapmbox

• Create a fake imap email account. Don't use a real name or password. We want the account to remain offline.
• Quit Mail
• In the Finder, open the directory holding the newly-created INBOX.imapmbox file (It's in ~/Library/Mail/IMAP-something/").
• Move this (empty) INBOX.imapmbox to the trash.
• Move the cached mail file you had copied to the Desktop to this folder. Rename the file to "INBOX.imapmbox".
• Start Mail again, and click on the new account name. Your messages should reappear.
• Copy the messages from this folder to another one, either IMAP or locally.
• In Mail's preferences, delete the account you had created.
  

Make sure you keep this fake account offline, or else Mail will overwrite your cached mailbox with an empty one!
