Recovering the Cyrus Admin password

You can’t recover the password as such. What you can do is reset it. To do that login to your IMAPD server as root and run:

saslpasswd2 cyrus-admin

Recovering a corrupt mailbox

Change to the cyrus user.
```
sudo su - cyrus
```
Change to the directory above the corrupt database. For example if the mailbox is user@example.com you would go to:
```
cd /var/spool/imap/domain/e/example.com/e
```
Then rebuild the mailbox
```
/usr/lib/cyrus-imapd/reconstruct -r -f -U user/user@example.com
```
Note: This is very extreme and may result in all your mail appearing in both the inbox and any sub folders you previously saved the message in.
