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 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

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, 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 ! --  Thiago Henrique adminlinux.com.br

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.

Hi, I have a "Ubuntu10.04 + dovecot-2.0.13" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. There is a lot of logs of "quota exceeded" like this: Oct 10 13:00:56 mailboxserver5 dovecot: lmtp(29105, user at mailboxserver5): Error: ifcIN1NxdVCxcQAAMBx7mQ: sieve: msgid=unspecified: failed to store into mailbox

Hi, I have a "ubuntu10.04 + dovecot-2.0.13" configuration in my server. It works fine with ~50k accounts. Recently I enabled TLS: $ cat /etc/dovecot/dovecot.conf ... # Use SSL ? ssl = yes ... The goal was to provide only IMAPS and POP3S. But Managesieve says "STARTTLS": $ telnet _MY_IP_ 2000 Trying _MY_IP_... Connected to _MY_IP_. Escape character is '^]'.

Hi, I have a "Ubuntu12.04 + dovecot-2.0.19" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. On average, my server has about 6K simultaneous imap connections during office hours. But I've noticed that this server has an average of approximately 4k connections in state "idling". On other Dovecot servers the

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):

Hi My servers are Ubuntu 14.04 and I'm needing to make a Upstart script for Poolmon. Does someone already made this and could to share with us ? Thanks! -- Thiago henrique

Hi, In my server, accounts are receiving many doubled emails in its mailbox. In some accounts the "doveadm deduplicate" is doing nothing, even if there are duplicate messages. But in some cases, this error has left me particularly concerned: # doveadm deduplicate -u <user> -m ALL doveadm(<user>): Panic: file mail-transaction-log.c: line 271 (mail_transaction_log_rotate):

Hi all! Does dovecot cluster (with Proxy/Director) work only distributed filesystems (like NFS) ? Is Dovecot-replication + Ext4 recommended for production environments? Thanks! -- Thiago Henrique

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. The message is still present in Server2. Could someone give me a hint reason for this ? Thanks in advance! -- Thiago Henrique ======================================================================

I plan to migrate my Dovecot IMAP servers to a clustered structure. I'm planning a cluster with high availability and load balancing. I know I need instances of Dovecot Proxy / Director. But these instances can be on another network? There is need for high network throughput between the Director and the backends? For me it would be cheaper to run Director in VM's at Amazon AWS for

Hello, In a Dovecot 2.0.6 server I have an account x at domain and an alias y at domain -> x at domain. When I send an email to x at domain with carbon copy to y at domain, X receives two messages on mailbox. Dovecot2 has any feature of duplicate suppression ? Thanks, Thiago Henrique

Hello, Is there any directive in Dovecot similar to 'imap_admins' of Cyrus? I plan to migrate from Cyrus to Dovecot. But I need a admin user which is able to obtain information about the quotas of common users. Thank you. -- []'s Thiago Henrique Network Administration Digirati Networks K8 Networks
