similar to: Converting old emails to compressed format

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

Hello, I am running dovecot 2.2.12 Current mail storage is sdbox and I am trying to compress all emails, which works fine, except for a few old mailboxes. If I run the following dsync command "dsync -u flea -o "mail_plugins=zlib" mirror maildir:~/ndbox" It fails with: dsync(flea): Error: Exporting mailbox INBOX failed: Backend doesn't support GUIDs, sync with header

Hello, I am trying to convert a dbox mailbox in maildir format I changed the config to maildir instead of dbox and I am issuing this /opt/dovecot/bin/dsync -u r convert dbox:/home/r/dbox But I get many errors like those below and no mail is stored in the maildir. dsync(r): Error: Corrupted mailbox log at offset 18446743970630342680: /home/r/dbox/dovecot.mailbox.log dsync(r): Error: dbox

Hello, I am running an asynchronously replicated mail setup. 2 servers are each running an smtp server which uses dovecot as the LDA. I am using unison to replicate mail files between servers. Before, I was using Maildir format and after reading so much good papers about the very good performance of dbox format, I decided to switch to dbox. However, I now have a very annoying problem, as mails

Hi, the zlib_save question reminds me of a wish: I think it's not possible to set zlib_save parameter per namespace (or even mailbox). Per namespace would be something for the wish list to get rid of the cron job method to compress archival mailboxes. And maybe an option to add a "Z" flag to compressed maildir message files as recommended in the wiki regarding compress crob job.

Hello: I have found the same problem reported above by Patrick Cernko affecting our system and corrupting our messages. Even worse, Outlook 2016 will no synchronize and the clients cannot see any message, even if there is only one corrupted mail per mailbox. I cannot figure out a feasible workaround for our system, and I can see that in new version 2.38 the bug is not fixed. Will

Hi I'm migrating some mailboxes from an old dovecot system where mailboxes are stored maildir uncompressed. I enabled zlib on the new system and migrated an account: doveadm -o mail_fsync=never backup -R -u tonyg imapc: when the account connects to the new system after a while i'm seeing the following error and the mailbox is no longer functioning: Jan 15 13:58:06 S611 dovecot:

I need to backup some of the mailboxes on our system. We are currently using mdbox with zlib compression plugin. The backups need to be maildir without compression. How can I accomplish this using dsync? The following just causes each msg file in maildir to be compressed as well. dsync -f -u user1 backup maildir:/var/tmp/user1 While this just causes the dsync to fail while spewing a bunch of

Hi All, I currently have a small Dovecot server (Server A) and I've installed a second dovecot mailbox server (server B) and am trying to sync mailboxes from Server A to Server B. Both servers sit behind two dovecot directors on separate hosts and have identical config files (doveconf -n output below). Mailboxes on Server A are on an NFS mount. Server A has been working fine with no

ok, I did install zstd (zstd command line interface 64-bits v1.4.4, by Yann Collet) reconfigured & compiled dovecot 2.3.10.1 again with option : with-zstd changed the configuration file to : zlib_save = zstd and restarted dovecot - now I have following log file errors : Aug 28 16:17:39 lxc-imap dovecot: imap(rnowotny)<237930><H1kft/CtENRUclcc>: Error: zlib_save: Unknown

I'm using dsync to synchronize emails on a laptop where wifi connectivity sometimes fails in the middle of a sync. I have a shell script that runs dsync, and here is one line of it including the output of dsync: + dsync -f -m realmail mirror /home/paulproteus/projects/ssh-attach/run ssh rose.makesad.us dsync dsync-local(paulproteus): Error: dbox

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

??? We have upgraded today from Dovecot 2.2.31 to Dovecot 2.2.33.2 and modified our config to include ITERINDEX in mail_location and we are detecting some errors like this: /Dec 13 08:17:31 buzon_rhel7 dovecot: imap(rboloix): Error: stat(/buzones/location/18/48/rboloix/mailboxes/SIT - Pra&AwE-cticas 2014/dbox-Mails) failed: No such file or directory// //Dec 13 08:40:24 buzon_rhel7

Hello, Maybe I am missing something obvious here (I would hope so), but is there any way to use dovecot deliver to spawn dsync to replicate changes. And dovecot to trigger dsync to sync mailboxes when a change has been done. Thanks -------------- next part -------------- A non-text attachment was scrubbed...

Thanks for that Aki. Follow-up question. I tried to initiate compression by adding mail_plugins = $mail_plugins zlib plugin { zlib_save_level = 6 zlib_save = xz } to dovecot.conf. I restarted dovecot and sent one message to the server, and one message from the server. Neither was compressed. I changed the save type to zlib_save = bz2 and repeated. This time the message
