similar to: cluster with dsync mirror

Will MultiMaster dsync work fine or will be big problems ? I configured dovecot to dsync from serv1 to serv2 to serv3 and repeat to serv1 to serv2 to serv3 and repeat... When email received to serv2, it will be synced to serv3, and serv3 will sync it to serv1, and serv1 will sync it to serv2 and will stop here because emails matched. What problems can be with this kind of configuration ?

Hi, I just upgraded from dovecot 2.2.19 to 2.3.2. "doveadm backup" worked fine in v 2.2.19, but now panics (user with shared folder): /opt/dovecot/bin/doveadm backup -u testuser -1 sdbox:/tmp/testuser dsync(standl2): Panic: file mailbox-attribute.c: line 360 (mailbox_attribute_get_stream): assertion failed: (value_r->value != NULL || value_r->value_stream != NULL) dsync(standl2):

I'm moving/converting email from one system to another The source system is: Dual core x86_64 6GB memory 180 GB raid1 disks ext4 Fedora 9 Dovecot 1.0.15 Maildir format The destination system is: Dual core x86_64 2GB memory 1TB raid1 disks ext4 Fedora 18 Dovecot 2.1.15 sdbox format I am moving mail in a series of steps: 0) cd ( to mail user home directory ) mkdir Maildir 1) # rsync mail

Hi, I was wondering... If one had mdbox ALT path set to a shared storage mount (say, on NFS) and one wanted to move a mailbox to a different host... I guess it in principle wouldn't be necessary to copy all the ALT storage through dsync, when the volume could just be mounted on the new host. Is there anyway for dsync to avoid moving Gigabytes of data for could just be "moved" by

Hi there, We're trying to convert users from Maildir to sdbox at present; I'm using dsync to achieve this (2.0.16) however when the user's have been converted we only get minimal information in the caching files. Is there some way to preserve all the caching decisions that were previously made so that when the user logs in to the new mailbox we don't have to cause an io storm

Is there any support for using Microsoft SQL Server 2005 or 2008 as the SQL database for users? Although I would prefer to do it other ways, the company I work for has all of their virtual hosting authentication tied into a SQL Server. Any ideas? Thank you. Bryan

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 Guys, I have a quite interesting problem. I have two servers that replicate to each-other. Suddenly one of the accounts is starting to eat a very large amount of disk space on, what basically is the replica for this account. doveadm-server seems to hang and keeps on filling the disk. I came across this message in the logs: Dec 8 07:36:40 <server> dovecot:

I'm considering setting up my own mailserver with Dovecot 2.0 (as soon as it's out) and SSD. I'm debating whether it's worth it or not. I have been running a mailserver with the Dovecot 1.1 train for a couple of years and it's been flawless and amazing. I'm thinking about using either FreeBSD 8.1 w/ZFS or OpenBSD 4.8-beta on a 64 GB or 80 GB SSD (Corsair or Intel) using

Hi there, I ran into an issue yesterday (dovecot 2.0) whereby when we dsync messages from a local machine (sdbox) to a remote (Maildir) which have different pop3_uidl_formats configured, the uidl format is not preserved. There doesn't seem to be any way to force this in the code, although I suspect that Maildir sources with saved pop3 uidls would pass them correctly. Attached is a rough patch

Gents, I'm relocating mailboxes to a new server. Before switching over to a new server I ran syncing a few times without any issues first I sync files with rsync from the old server to have a local copy, then I sync mailboxes with dsync /usr/bin/doveadm -Dv sync -u $MBOX -R "sdbox:/srv/vmail/temp/srv/srv.bgoperator.ru/${MBOX}:DIRNAME=DbOx-mAiLs" After switching over smtp

I am trying to run asterisk on Trustix 2.1 w/updates. Has anyone had any troubles related to zaptel hardware like sporadic errors when trying to dial out? Also, what is the consensus for the best Linux distribution to run asterisk on? Trustix seems like a nice choice but I would like to hear the recommendations. Thank you for your help. Bryan

I'm using dsync to synchronize emails on a laptop where wifi connectivity sometimes fails in the middle of a sync. I have a shell script that runs dsync, and here is one line of it including the output of dsync: + dsync -f -m realmail mirror /home/paulproteus/projects/ssh-attach/run ssh rose.makesad.us dsync dsync-local(paulproteus): Error: dbox

Hello, I'm using 2.2.13 on Debian stable, and I perform regular dsync backups. Typically if there is an error, dsync can recover from it the next time it is run, but I've been encountering a new error that doesn't seem to self-heal: # /usr/bin/dsync -u gae backup ssh -i /root/.ssh/id_rsa backmaildir at internal.example /usr/bin/dsync -u micah dsync-remote(micah): Error:

Im trying to sync 2 mailserver with dsync mirror functionality. Problem occurs when mails arrive in the same folder on both sides then dsync sometimes runs into problems and duplicates that entrys on both side(2mails then with same content). After running again the same happens again(now 4 mails with same content on every side). And then duplicates this mails on both sides on every run :(
