My mail database appears to be corrupted because the accounts list in the Server Admin Mail Window reads as follow "Unknown mailbox path" under Mail Store field.

I´ve got log messages like "Aug 21 03:11:40 www imapd[11327]: Fatal error: can't initialize mboxlist environment" or "Aug 21 03:41:32 www ctl_cyrusdb[11831]: checkpointing cyrus databases
Aug 21 03:41:32 www ctl_cyrusdb[11831]: DBERROR db4: fatal region error detected; run recovery
Aug 21 03:41:32 www ctl_cyrusdb[11831]: DBERROR: dbenv->open '/var/imap/db' failed: DB_RUNRECOVERY: Fatal error, run database recovery
Aug 21 03:41:32 www ctl_cyrusdb[11831]: DBERROR: init /var/imap/db: cyrusdb error
Aug 21 03:41:32 www ctl_cyrusdb[11831]: done checkpointing cyrus databases"

The first problem is that I can´t execute the "reconstruct" command because I was unable to login as the "cyrus" user (required for this task).

Mac OS X Server 10.3

What can I do? Any replies will be very appreciated.

Thanks in advance.

You invoke the "cyrus" user in Terminal only you do not actually login as cyrus.

The process I have followed in the past was pulled from the Apple Discussion boards. You must follow it exactly. And remember to make a copy of your mail as indicated.

Your problem may have been caused by the mail log issue. Basically when postfix needs to create a new log file it gets the permissions incorrect. There is a separate procedure posted on how to create empty log files and set the correct permissions.

Your mileage may vary.


============

First, go into Workgroup Manager and setting prferences to show all sytem users, select cyrus user, advanced tab, give him a shell (I chose bash)

now go to terminal and follow these directions from the discussion above:

" First, stop the mail service then back up /var/imap to somewhere safe using either ditto or cp -Rp from the command line (as root) Also do this with /var/spool/imap (this is where all your mail is stored)

Then (holding your breath) as root, rm -rf /var/imap

Now (still as root) run /usr/bin/cyrus/tools/mkimap

This will recreate /var/imap from scratch.

Now you must run:

chown -R cyrus /var/imap
chgrp -R mail /var/imap

Now su to the cyrus user - type "su cyrus (return)"

run /usr/bin/cyrus/bin/reconstruct -i (an undocumented flag that insures all folders will be recovered (not just inbox)

sudo -u cyrus /usr/bin/cyrus/bin/reconstruct -i

in my Server Admin Mail Window reads as follow "Unknown mailbox path" under Mail Store field.

I Just readed the posts to know how to fix it, but unfortunatly I did´n understand.

I`m wibdering if you can explain all the steps, because I`m new in Mac OS X Panther Server

Thanks a lot
