I'm getting an error backing up mailboxes. I'm using the mirror command: dsync -fvo mail_home=/home/users/bob mirror ssh vmail at 10.1.4.1 dsync -o mail_home=/home/.incoming_mail_migrations/users/bob dsync-remote(vmail): Error: Mailboxes don't have unique GUIDs: 1ef6ee37c694894d783100000581a675 is shared by INBOX and INBOX dsync-remote(vmail): Error: command BOX-LIST failed

More dsync issues. We were running 2.1.7 and we updated to 2.1.9. Same problem with both versions. I'm getting an error 75 on about 40 boxes out of 1800. It is the same list of boxes every time we use 'dsync backup' to backup the server. dsync seems to stop communicating to the backup box (over ssh). strace just shows it sitting at a epoll_wait. Once the program quits (times out?), a

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

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

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

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

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

Hello, when calling doveadm backup like in the following example, it seems to flush every email to disk maxing out harddrives (iops) and resulting in very poor performance: Calling doveadm -o plugin/quota= backup -u "statusmails at domain.com" "mdbox:/backup/vmail/domain.com/statusmails" finished in 212 secs [changes:1800 copy:1800 delete:0 expunge:0] The source mdbox holds

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

Trying to clean up the last of the corruption caused by my own stupidity. I now have two mailboxes for one user that give errors such as: doveadm(fax at amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.9): gz trailer has wrong CRC value at 20065618 doveadm(fax at amfes.com): Error: read(/var/mail/amfes.com/fax/mdbox/storage/m.9) failed: Invalid argument (uid=238)

Hi guys, I'm running dovecot/postfix on my Debian Jessie maschine: # dovecot --version 2.2.13 doveconf -n output: http://p.bastelfreak.de/HsVwS/ today I migrated from maildir(located at /var/vmail) to mdbox with these commands: rsync -av -f"+ */" -f"- *" /var/vmail/ /home/vmail/ rm /home/vmail/*/*/Maildir -rf for i in $(doveadm user \*); do u=$(echo $i | cut -d@ -f1);

Yes I have done it, it is the third command I have run, without any change. a.
