similar to: Dovecot and zlib

After nearly running out of space I swapped in larger disks and then saw the recent threads about zlib compression. Unfortunately I'm still confused after reading <http://wiki2.dovecot.org/Plugins/Zlib>. In order to compress new email being stored do I only need to change 10-mail.conf to this: mail_plugins = $mail_plugins zlib and 90-plugin.conf to this: plugin { zlib_save_level = 6

Hi, I'm working on enabling the zlib plugin and compressing most of the mail on my mail server, and I've run into a bit of a problem with doing things as described on the wiki's zlib plugin page (here: http://wiki.dovecot.org/Plugins/Zlib). I'm using Dovecot 1.2.15 and maildir as a mailbox format on Debian 5. I have a script that implements the steps listed at the bottom of the

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

While migrating users from Cyrus IMAP v2.3.14 to Dovecot 2.2.12 (compiled from source) dsync aborts with a backtrace on some (maybe 15 out of 800) mail accounts: (same error happens wiht or without -f flag) dsync -D -v -o mail_fsync=never mirror -f -R -u user at domain imapc: <snip> dsync(user at domain.com): Debug: brain M: in state=sync_mails dsync(user at domain.com): Debug: brain M:

hi, Could anyone give some info on this plugin? When i read the wiki (http://wiki.dovecot.org/Plugins/Zlib) i'm still left with some questions... I use Maildir to store my mails, if i enable this zlib-plugin, should i 'manually' compress all messages? or wil the uncompressed messages still be accessible by dovecot? wil new messages be compressed automagically? how should the

I enabled zlib compression, so new mails are saved compressed. Now I want to convert the old mails to gzip with the find and gzip command, but now I don't know which files are already gzip compressed by dovecot. Shouldn't zlib_save itself add Z to the Maildir flags? As suggested in the compress guide on http://wiki2.dovecot.org/Plugins/Zlib ? -- Tom

Historically we've done the former. The latter would require Chris wanting to do that. -eric On Tue, Apr 16, 2013 at 11:52 AM, Alexey Samsonov <samsonov at google.com> wrote: > Just in case - do we want to link with libz.so installed in the system, or > be self-contained and copy sources to LLVM repo? > > > On Tue, Apr 16, 2013 at 10:48 PM, Eric Christopher <echristo

Hi, I'm wondering if someone already implemented a compression script (and would like to share it) based on the step-by-step provided on wiki page of Zlib module. I can already do some find|xargs gzip .... but couldnt implement it completly as described on the wiki page. I know the suggested step-by-step is very detailed and probably a must simplier will be enough for almost

Hi, faced with a current space problem on our dovecot 2.2.18 server, I thought about using the zlib plugin. My questions: - is it really as simple as adding the options to the conf files as described in the docs :) ? http://wiki2.dovecot.org/Plugins/Zlib - As this just compresses new messages; dose anybody has a sort of simple cron or whatever script or best practice how to compress existing

Just in case - do we want to link with libz.so installed in the system, or be self-contained and copy sources to LLVM repo?

Hi all, I am quite happily running a dovecot setup with maildirs. This was once running courier but since the migration I have never ever looked back. Now, with growing userbase I?m looking into using zlib compression and mdbox instead of maildir. This seems to go quite well using dsync on a testbed server. So let?s go production! Before final decision I came across this: - I?m using a spam

Hi, I run a small IMAP server for a dozen guys in the office, serving about 55GB of Maildir. I recently became aware of the Zlib plugin ( http://wiki2.dovecot.org/Plugins/Zlib ) and wondered 1. given that there is about zero CPU load on my IMAP server, is enabling the plugin a no-brainer or are there other things (except CPU load) to consider? 2. For enabling the plugin, I suppose you

zstd support was added in v2.3.11 (not v2.3.12 like I mistakenly tried to say in the earlier mail). > On 28.
