OK, I managed to reconstruct my test mailbox. The files that were in my directory structure but not visible in the mailbox are now all visible in my email client.
Unfortunately, the cyrreconstruct command is not verbose at all and I cannot see the filenames corresponding to rediscovered emails (so I cannot delete them...).2014-04-23 15:22 GMT+02:00 Y B <ybpubs@xxxxxxxxx>:
this seems to be a good way to reach my goal. Unfortunately, my version of cyrreconstruct does not accept the -n option :
cyrreconstruct [ -C config-file ] [ -p partition ] [ -x ] [ -r ] [ -f ] mailbox...
cyrreconstruct [ -C config-file ] -m
Using cyradm and reconstruct does not allow the -n either, only the recursive flag is allowed (-r).
I tried to reconstruct the mailbox anyway but nothing seems to happen (i ran the command on a mailbox with one email in INBOX and ten email files but after the execution of the command, nothing changes).

Any solution in my case?Thanks

Yes, metadata files are the cyrus.* files. What version of Cyrus are you running? You should be able to run reconstruct on the mailboxes with the -n option which should list the files that reconstruct would have added back to the index if the -n option was not used. Use this output to determine which files can be deleted.On 04/23/2014 08:45 AM, Y B wrote:
thanks for the answer.
I certainly still have the metadata since I have not lost any file, I
have just too many files (all the previously deleted emails, recovered
from my rsync backup)
I am not exactly sure where the metadata are situated, /var/imap does
not exist. In my case, all email files are situated at
/data/mail/imap/spool/*/user/username (the star being any letter of the
alphabet).
For a given username, I have for example the following files:
-rw------- 1 cyrus mail 21183 Apr 23 11:01 4846.
-rw------- 1 cyrus mail 26585 Apr 23 10:49 4845.
-rw------- 1 cyrus mail 15720 Apr 23 10:39 4844.
-rw------- 1 cyrus mail 4496548 Apr 23 13:36 cyrus.cache
-rw------- 1 cyrus mail 251 Mar 10 16:52 cyrus.header
-rw------- 1 cyrus mail 151816 Apr 23 13:36 cyrus.index
-rw------- 1 cyrus mail 10087920 Jan 22 02:28 cyrus.squat
drwx------ 2 cyrus mail 69632 Apr 23 13:11 Sent
drwx------ 2 cyrus mail 4096 Apr 23 09:38 Drafts
drwx------ 4 cyrus mail 69632 Apr 22 20:45 Trash
drwx------ 2 cyrus mail 4096 Apr 22 20:30 spam
Are the metadata in the cyrus.* files?
If yes, is there an easy way to delete the old emails using these metadata?
Thank you.
Yannick
For example I added some bogus files called 1. , 101. , and 255. to my mailbox.
reconstruct -n user.boutilpj
user.boutilpj uid 1 rediscovered - appending
user.boutilpj uid 101 rediscovered - appending
user.boutilpj uid 255 rediscovered - appending
user.boutilpj

Hello,
after a disk crash, I had to recover all the emails from a daily
backup.
Unfortunately, I noticed that this backup was made with the rsync
command but WITHOUT the --delete options.
That means that the mail backup was much larger than the
original one
since no message was ever deleted on the backup.
Now I would like to clean the mailboxes and remove all those
emails that
were previously deleted but I cannot find how.
Is there any easy way to do this?
(I use cyrus+postfix on debian 6.0.4)
Thank you for your help.
Did you lose your metadata as well? Usually in /var/imap ?
