Chapter 2 Mail Service Maintenance 35

Working With the Mail Store and Database

The mail database keeps track of messages for all mail service users. Mail service stores

messages in separate files. You can do the following with the mail database and files:

• Repair the Mail Store Database.

• Convert the mail database from an earlier version of Mac OS X Server.

• Specify the location where the mail database and files are stored.

• Backup and restore the mail store.

All these tasks are described in this section.

Repairing the Mail Store Database

The mail service updates the database of stored messages each time a message is

added, deleted, or moved. Sometimes during these updates, the mailstore’s database

can become corrupted. When users report that mail messages have “disappeared” or

become unreadable, the mail store database may be corrupted and need to be

reconstructed.

Reconstructing a database can be done while the mail server is running. Additionally, it

can be directed for any user to reconstruct only the affected mailboxes.

To reconstruct a corrupted database:

1 Start Terminal.app.

2 As root user, change to the cyrus user:

su cyrus

3 Enter the following command:

/usr/bin/cyrus/bin/reconstruct -r -f /var/spool/imap/[user name]

For more information about the reconstruct command, see their man pages by

entering:

man reconstruct.
