Recently updated to 2.2.25. Noticed a migration script I've been previously running fine started giving me the errors below.

Anyone know how to setup dovecot with mdbox so that it can be used through shared storage from multiple hosts? I've setup a gluster volume and am sharing it between 2 test clients. I'm using postfix/dovecot LDA for delivery and I'm using postal to send mail between 40 users. In doing this, I'm seeing these errors in the logs Mar 21 09:36:29 test-gluster-client2 dovecot:

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

Thank you Vitalii. Could you please tell me / do you know if those dovecot* files have to be also backed / archived?

Hi, I'm using mdbox now (Dovecot 2.2.4), with indexes on a separate disk. Works fine, but the directories for indexes are also present in the storage folder, and are empty. Userdb (sql) returns this: home /var/vmail/domains/somedomain/someuser mail mdbox:~/mdbox:INDEX=/mnt/spool/dovecot/index/somedomain/s/someuser And the created directory structure is:

I saw that before but there is only maildir -> mdbox but not mdbox -> maildir Did I have missed anything there? ?On 6/18/19, 9:59 PM, "dovecot on behalf of @lbutlr via dovecot" <dovecot-bounces at dovecot.org on behalf of dovecot at dovecot.org> wrote: > On 18 Jun 2019, at 15:18, Benny Pedersen via dovecot <dovecot at dovecot.org> wrote: >

Hi, I have a "ubuntu10.04 + ext4-filesystem + dovecot-2.0.13 +mdbox" configuration in my server. It works fine with ~50k accounts. Recently happened a filesystem corruption in a device of StMailLocation and I fix with fsck.ext4. After this crash, one account began to show access timeout and errors like this on force-resync: # doveadm force-resync -u account INBOX doveadm(account):

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I

Reviewing some mailing list archives and the wiki, I still don't have a real clear picture of why I'd want to use mdbox. What I've taken from the info I've reviewed says mdbox is more complicated (than sdbox), has greater potential for breakage (simply because it's more complex), and has a theoretical performance impact depending on the exact filesystem/hardware used.

Hi How can I convert all virtual mailboxes from maildir to mdbox? Manually, one by one, working, but I have a lot ... Virtual users and domains stored in sql database. Thats what I want: mail_location = maildir:/var/vmail/%d/%n/Maildir to mail_location = mdbox:/var/vmail/%d/%n/mdbox Thanks Levi -------------- next part -------------- A non-text attachment was scrubbed...

Hello, I would like to convert all users mail from maildir to mdbox. My Dovecot version is 2.0.1, converted from 1.2.13 but config was rewritten from scratch. http://wiki2.dovecot.org/Migration/MailFormat says following: maildir -> mdbox migration. Set mail_location=mdbox:~/mdbox and run doveadm convert -u username maildir:~/Maildir but doveadm does not know a command like

Hello, I am using dovecot with mdbox+sis and I notice an ever increasing disk space usage since I converted mailboxes from Maildir to mdboxes. I have checked with a user and while it actually uses only 65K, his mdbox files on disk are more than 6G. The backup of his mailbox is just 64K. Any suggestions ? Below are some relevant commands: [root at mail ~]# doveadm quota get -u test Quota

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

Hello I'm using mdbox for mail storage. I'd like to give users an option to recover backups into a new folder, say, Backup-$date. Is there a simple way to do this? I was looking at tools like dsync and doveadm-altmove but apparently they're not intended for this kind of stuff. Thanks in advance, Andre

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

I?m considering moving from maildir to mdbox, but don?t quite see how I should do the conversion with minimal downtime. Our userdb is ldap, and the we use this setting to point to the users maildirectory: user_attrs = mailMessageStore=mail=maildir:%$:INDEX=/indexes/%1u/%1.1u/%u,mailQuota=quota_rule=*:storage=%$ i.e. every user has a "mailMessageStore" attribute in LDAP that points to
