Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but

Thanks Jack. That's good to know. It is definitely something to consider. In a distributed storage scenario we might build a dedicated pool for that and tune the pool as more capacity or performance is needed.

With a single server - and no intent to have a second server online at this time - is it possible to use the replication service to keep a "live" backup? Or otherwise perform a storage format conversion? I'm presently using sdbox - and considering going back to mdbox though without SIS.? My intent now is ONLY a 1-way backup, to be kept current, and no clients will utilize the

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

Silly question? Which is preferred? MailDir or Mbox? (directory vs flat file) How would you do this when migrating from an old server to a new one?

I'm sending this message to both dovecot and ceph-users ML so please don't mind if something seems too obvious for you. Hi, I have a question for both dovecot and ceph lists and below I'll explain what's going on. Regarding dbox format (https://wiki2.dovecot.org/MailboxFormat/dbox), when using sdbox, a new file is stored for each email message. When using mdbox, multiple

To a degree I agree .. given mdbox doesnt delete until purge .. but then would be nice if purge took a dovecot search rather than just ditch everything with refcount=0 ... in that way could say purge everything thats been marked as delete according to a specified criteria. rgds Matt completly unrelated moved mailserver back home and listed on cyren so atm getting bounced by dovecot.fi .. have

It's apparent I have some level of corruption in my mailboxes - something to do with the combination of mdbox, sis, and zlib. I should note that I know I have a mix of compressed and raw messages - if that makes any difference in identifying the problems. I think I need to somehow regenerate the mailboxes with issues. Is there a suggestion for how to accomplish this? Should I perhaps use

Hi, I replaced HDDs in my home server and reinstalled the OS (Ubuntu 17.04). Since I had some time I reviewed my Dovecot configuration and changed a couple of things, including mailbox format. Now I would like to migrate e-mail (about 20G -- I use this server as an e-mail archive). The Maildir is available on the (old) hard disk. The new dovecot is running. What should I use? Would mbsync work?

Hi Guys, I've been desperately trying to find some comparative performance information about the different mailbox formats supported by Dovecot in order to make an assessment on which format is right for our environment. This is a brand new build, with customer mailboxes to be migrated in over the course of 3-4 months. Some details on our new environment: * Approximately 1.6M+

Why things happen is one of the great mysteries and joys of being a sysadmin... As for cleaning up SIS, I believe the "doveadm purge" command takes care of it. I have a daily cronjob which includes: #!/bin/sh # Permanently expunge old Trash doveadm expunge -A mailbox Trash savedbefore 2w # Optimize mdbox storage doveadm purge -A # Update fts indexes doveadm fts rescan -A -- Daniel

Hello everyone, I am currently evaluating dovecot for our new email production servers (20k+ mailboxes) and found out something strange. I'm using those settings on Dovecot 2.2.4 (x86_64 / Slackware / compiled from sources) mdbox_rotate_size = 128M mdbox_rotate_interval = 1d mdbox_preallocate_space = yes with virtual users and location like : mail_location = mdbox:~/mdbox I don't

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.

hi i was carrying out some testing using qmailtoaster with dovecot on a centos 64 server i am connecting to the mailbox using a windows machine with outlook across the lan. the mailbox is around 7gb in size with around 12000 emails spread across multiple folders and i am trying to sync the mailbox folders to by creating an account imap account in outlook. the mails are getting downloaded in

Hi all, We are currently using snapshots and rsync to backup a large mail server to a backup mail server. I have been looking into using dsync to replace rsync in hopes that it would make backups more efficient. I decided to test the performance using a single mailbox. Unfortunately dsync seems to run much slower than rsync. Rsync was able to sync the mailbox in 2 seconds. dsync took over
