similar to: Enable compression only for namespace with mdbox storage

Currently there is no way to enable compression per namespace.

Like mentioned here https://www.dovecot.org/pipermail/dovecot/2013-March/089084.html I have a namespace with mbox and a namespace with mdbox mailboxes. How do I only enable the compression for the mdbox mailboxes?

I have test environment to determine what would be best settings. I have been told that enabling zlib compression would be good to save iops on storage. But doing the test now, I get worse results. [@test2 ~]# pr -m -t mail04-mdbox-vdb-append-64kb-6.log mail04-mdbox-vdb-append-64kb-8.log |less Logi Sele Appe Logi Sele Appe 100% 100% 100% 100% 100%

If I do the same test[1] with mbox I can store around 31k messages and mdbox 16k messages. I noticed also that cpu and disk utilization with mdbox was not very high, while disk utilization on mbox was much higher. That makes me wonder if I can tune mdbox to have better performance?

Yes, I have still inbox mbox format because I have sendmail delivering there. I trying to migrate/convert step by step, with least possible impact for users. -----Original Message----- From: Aki Tuomi Sent: dinsdag 14 mei 2019 6:19 To: Marc Roos; Marc Roos via dovecot Subject: Re: Userdb userdb_mail=, error Mailbox list driver maildir++: maildir_name not supported by this driver > On

With this setting, all folders are empty, I guess understandable, because the mdbox has its own indexes stored locally with it. Does not explain though why inbox is empty. [@ dovecot]# cat special-userdb test:x:8267:231:Account with special settings for dovecot:/home/popusers/test:/bin/false:userdb_mail=mdbox:~/mdbox:INBOX=/ var/spool/mail/%u:INDEX=/var/dovecot/%u/index With this setting

I think sdbox or mdbox format is what you are looking for > On 2 Dec 2018, at 09:47, Marc Roos <M.Roos at f1-outsourcing.eu> wrote: > > > No one an idea?

I have this default configuration [0], when use the userdb_mail to point to the mdbox location, the inbox subfolders show differently in a firebird client. So I decided to copy the whole default mail_location into the userdb_mail configuration [2]. But then I get errors [3]. Should I change the namespace configuration here, how? My default namespaces are inbox and 4archives [0] [@ ]#

Yesterday I had to recover an e-mail which a user had deleted. If I understand this correctly the message was expunged but not purged (doveadm purge had not been run). This e-mail was clearly still in the mdbox stored with zlib compression as I could tell using the doveadm dump command (doveadm dump -t dbox filename). I could however not reveal the e-mail with the normal doveadm fetch -u

I've got Dovecot 2.2r5 (Ubuntu package version 2:2.2.0~rc5-0~auto+1 from the "testing-auto/dovecot-2.2" repository on xi.rename-it.nl) running on a brand-new Ubuntu 12.04.2 server. I'm trying to configure Dovecot (using the "mdbox" mailbox format) to allow folders to contain both messages and sub-folders. However, it's not working consistently. I need to have

Hi! When I force-resync a mailbox of mine, I see following output: # doveadm force-resync -u $USER $PATH doveadm($USER): Warning: mdbox .../storage: Inconsistency in map index ($X,$Y2 != $X,$Y2) doveadm($USER): Warning: fscking index file .../storage/dovecot.map.index doveadm($USER): Warning: mdbox .../storage: rebuilding indexes doveadm($USER): Error: mdbox .../storage: Duplicate GUID $G in

I was wondering if I should add compression support to mdbox one mail at a time or one file (~2MB) at a time. The tradeoffs are: * one mail at a time allows quickly seeking to wanted mail inside the file, but it can't compress mails as well * one file at a time compresses better, but seeking is slow because it can only be done by uncompressing all the data until the wanted offset is reached

Hi Timo, we are currently running dovecot 2.1.10 using mdbox storage. Sometimes we get requests from users to restore accidentally deleted mails. If the mails got deleted before a backup was made, such mails could of course not be restored from backup. One option to help users in this respect would be to use the lazy expunge plugin. On the other hand I have seen, that the deleted mails stay

Hi, I need advice on how virus scan and removal can be done on a _mdbox_ mail storage? On a maildir storage the virus scanner (e.g. clamav etc.) can detect and remove a email that is infected, since every email and attachment are stored in separate files. But in mdbox the emails and attachments are compressed together in one ore more mdbox-files ... I am anxious to convert my mail

But is that not adviced in the manual[1]? I am also in the process of setting up dovecot behind a haproxy. Still testing with this. I was wondering why one would choose haproxy and not eg dovecot proxy (with director) [1] https://wiki2.dovecot.org/HAProxy -----Original Message----- From: Zelic Bojan [mailto:bojan.zelic at kudelskisecurity.com] Sent: woensdag 26 augustus 2020 23:39 To:

Hi Martin, I feel a bit like an idiot, but I have been trying with copy, so I do not lose any message when testing. But I can't get them to copy. I do indeed have same uid and gid.
