Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial

Hi, In a cluster with two servers and replication via dovecot-dsync, this error is logged: server1 dovecot: dsync-server(<user>): Error: Couldn't create lock /var/lib/imap/user/6a/<user>/.dovecot-sync.lock: No such file or directory This is because "/var/lib/imap/user/6a/<user>/" doesn't exist in server1. In another cluster node, the directory exists and

My users are like this "username=domain_name". Could the '=' character be the reason? Despite my settings always worked: # doveconf auth_username_chars auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@= All opinions are welcome.

Hi! I have two Dovecot-2.2.13 servers with Dsync Replication: server1 and server2. When I execute 'EXPUNGE' on server1 side, the messages with FLAG \Deleted are expunged only on server1.

Hi, In my company, we have several failover clusters (~50k accounts per cluster) with Ubuntu12.04 and Dovecot-2.0.19 (without dsync, replication at block level with DRBD). We are migrating to active/active clusters with Ubuntu14.04 and Dovecot-2.2.15 with replication via dovecot-dsync. Each new cluster consists of two machines and each machine runs two instances of Dovecot (one for backend

Hi, I would like to take advantage of new features in Dovecot 2.2 on my servers. But I'm having difficulties to build packages for Ubuntu-12.04-LTS. Does anyone know a repository that has new stable versions for Dovecot and Pigeonhole ? Thanks ! --&nbsp; Thiago Henrique adminlinux.com.br

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>. I have many users who do not yet have their userdb_home directories created on the server, because that is created at the time of first login. I'm testing dsync for replication and have seen the following error: dsync-server(<user>): Error: Couldn't

Hi, I am using dovecot version 2.1.3 on centos. I tested dsync from my live server to one of backup server. But I got that its working for most of the user and there is problem for few user.

Please tell me about Dsync replicator. The following are set to enable the "replication" plug-in /etc/dovecot/conf.d/10-mail.conf *---mail_plugins = notify replication---* And I made the following file /etc/dovecot/conf.d/30-dsync.conf *---service replicator { process_min_avail = 1} dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server

Does Dovecot Director health monitoring of backend servers ? Or is poolmon (http://www.dovecot.org/list/dovecot/2010-August/051946.html) the best option for this? Maybe Ldirectord? Thanks! -- Thiago Henrique www.adminlinux.com.br

Hi, I have a "ubuntu10.04 + ext4-filesystem + dovecot-2.0.13 +mdbox" configuration in my server. It works fine with ~50k accounts.

Hi, I'm trying to use the Dsync cluster feature in a simple setup, without director, but I'm having some troubles. First of all, I want to know if this functionality syncs the mailbox when the user receive a mail or only when the dovecot starts? Reading the Dovecot mailing list and the design description for a dsync-replicated Dovecot cluster, I understood that it should sync every time
