Hello. I'm install latest dovecot 1.2 from hg repo. I have many messages in maildir+ format. I migrate some folders to dbxo format using instructions from http://wiki.dovecot.org/MailboxFormat/dbox. But in two folders i'm delete index.cache and index.log files, this is my mistake. Is that possible to recover this files (regenerate) or use my messages from maildir with dbox? Thank You for

Hi, I originally picked mdbox because I had the impression from reading about it on the mailing list that it was more performant and that it would conserve disc space. But lately i found mailboxes have nearly double the storage as reported. I mean, IMAP QUOTA reports around 900MB for one account that has over 2GB when I inspect the mail location of the user using the linux command `du`

The Dovecot wiki [1] doesn't list either Exim, Postfix or anything else as supporting the dbox. I did some searching in the Exim archives and have found only one message mentioning dbox, sdbox or mdbox. [2] I think an RFC would go a long way towards getting the format supported. Has Timo, or anyone else, considered submitting an RFC to the IETF? My question was how are we going to use it

Hello Actually we use MBOX format for all our IMAP access but users complain they cannot create subfolders in imap folders, of course they cannot because of MBOX format ... I need gurus advices on changing mailbox format Maildir of Dbox ? What would be the safest way to go ? Note : we extensively use Thunderbird here. Thanks

Hello I have read carefully about dbox (/http://wiki2.dovecot.org/MailboxFormat/dbox/) and I have some questions: - One of the main advantages (speed wise) of dbox over maildir is that index files are the only storage for message flags and keywords. What happens when we want to recover some messages from backup? With maildir we can rebuild message indexes, but I am not sure about

There are many like it, but this one is mine. David, in particular, is there some question you feel that the wiki fails to answer? Aki

What are the pros and cons of both? Especially in regards to performance, stability, management & maintenance? I really appreciate feedback. We're on a time-crunch to migrate from a debian 5 box w/ dovecot 1.1 to a debian 6 box w/ dovecot 2.0.9 (built from source).

I've updated http://wiki2.dovecot.org/MailLocation regarding a typical mail_location entry for dbox. Previously it said: mail_location = dbox:~/dbox but of course "dbox" is now the old name for "sdbox", so the example should be updated to say "sdbox" and there might/ought also to be an example for "mdbox". In

Hello Dovecoters, I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u user1 at user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times).

Hello, As per wiki instructions, I tried to enable zlib compression of mails by adding/modifying the following snippets of configuration: plugin { zlib_save_level = 6 zlib_save = gz } and protocol imap { mail_plugins = fts fts_squat autocreate zlib imap_zlib imap_id_log = * } I am using dbox format and delivering the mails via dovecot deliver, however mails don't seem

Doing a "doveadm purge" today I got this: """ doveadm(jcea): Error: Corrupted dbox file /home/jcea/.thunderbird/dovecot/storage/m.686 (around offset=1385772): purging found mismatched offsets (1385742 vs 1380664, 185/275) doveadm(jcea): Warning: fscking index file /home/jcea/.thunderbird/dovecot/storage/dovecot.map.index doveadm(jcea): Warning: mdbox

It has been my wish to move to dbox for a long time hoping to reduce the number of writes which is really killing us. Now I wonder what may be the best way of doing so. I'm considering some sort of intermediate migration where the existing Maildir users are changed to single-dbox and then later upgraded to 2.0 and changed to multi-dbox when it becomes stable. But is this a reasonable task

I'd like to give the dbox format a try, but I could not find any information on how to enable it. There's information on how to set mail_location for the Maildir and mbox formats in the wiki and also in the commented configuration file, but how to set it for dbox is strangely missing. I took a guess with 'mail_location = dbox:~/dbox', but that didn't work, so it's probably

Hi, I am contemplating migrating from maildir to dbox. However, I wonder about the maturity of the dbox code, as it appears to not be widely used. Does anybody have some success stories? My primary driver is to have non-changing file names, and thus smaller backup deltas. Are there other advantages that I should pursue? I read in the wiki that the migration is straightforward, but I did not

Hello, So ive spent the last 45 minutes or so searching the list for dbox stuff, but Im not seeing anything real definitive. My question is basically whether the dbox format is ready for production environment, is sdbox or mdbox more stable/ready than the other or does it matter? What are people's experience/review with running this format (and if you reply can you tell me which one

Hi Timo, I've just setup Dovecot v1.2.rc5 and switched the mailbox format of one account to dbox. Therefor I've created an empty directory, called dbox, with access mode 0700, like the user's home directory. After the IMAP login with Thunderbird some dboxes was created. All permissions were set fine (0700 / 0600), except the permissions for the files: *

Hello people, Since the invention of this storage called dbox, I have never quite gotten round to understanding it, nor getting to use it. It seems so strange to me and I must ask a few stupid questions about it. I use the MTA to deliver mail to Maildir, either in ~/Maildir or /some/path/%d/%n/Maildir. It has always beat me how dbox comes into play under such circumstances. From the wiki, I see

Hi Timo, playing a lot with dbox but folder deletion seems to me broken, whatever setting i tested i cant delete subfolders with thunderbird, i first thought about acls but deactivate acl didnt helped splitting control an index files from dbox also didnt work, i cant find any failure message in the logs, but there is also no entry for delete trys all debug level are in the highest stage on this
