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, 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 ...

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".

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):

I have a CentOS 6.5 server running as a host for about a dozen other VM's, and all were running just fine. I had a mix of CentOS, Ubuntu, and FreeBSD VM's running, no problem at all. I then updated the Ubuntu VM's to the newer 14.x release, and that installed a 3.13 linux kernel, and after that (which I didn't notice right at the start) the network throughput outbound was

Hi All, I have posted this messgage yesterday in the Beowulf mailing list, and did not get any responses, as i have tried different Centos kernels to see if the behaviour changes or not, and it did not change much, I am posting it here, I hope no one minds, and thanks in advance for any pointers or clues? ---------- Forwarded message ---------- From: Walid <walid.shaari at gmail.com>

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 all! Do I need one Dovecot Proxy/Director for each Dovecot Replicate Cluster ? Isn't possible to put a Dovecot Proxy/Director on the border of multiple clusters ? Thanks! -- Thiago Henrique www.adminlinux.com.br

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.

Hi, I am currently in the process of improving performance for a Samba 3.3.4 server on FreeBSD 7.0. The samba server works great when mounted from another machine located on the same network but when I try to use it over our corporate VPN (OpenVPN with tap interface) the throughput won't go over 4,5 Mbps. The ping between the samba client and the server is around 20ms. I have used a linux
