v2.1.10: Director director_servers order issue
Hi,
I'm setting up an IMAP/POP cluster using dovecot director for some NFS
reasons and I'm getting some troubles with director_servers directive.
Configuration is shared on both nodes :
director_servers = 10.0.50.50 10.0.50.51
director_mail_servers = 192.168.0.150 192.168.0.151
director_user_expire = 15 min
service director {
unix_listener login/director {
mode = 0666
}

director with multiple instances
I'm experiencing some problems similar to those described in
http://dovecot.org/list/dovecot/2012-July/137250.html
except with 2.0.9.
Adding http://dovecot.org/list/dovecot/2012-July/084906.html
to the main config didn't seem to help, nor did setting the list of
director and backend servers to just the system itself.
I get a banner connecting to port 143:

4sec latency when using director
Hi,
I've been running dovecot for many years, but now i've hit a strange
problem.
when retrieving imap there is sometimes in 1 of 4 imap requests a 4sec
latency.
* notes:
- connected directly to the backends this latency disappears
- removing a director from the loadbalancer(lvs) so i'm the only connected
to the director
this latency disappears too
I would appreciate some feedback

Problems with IMAP/POP and dovecot director on backend (director_proxy_maybe)
Hello dovecot community,
first of all: dovecot ist great! ;) ...nevertheless I?ve got some
problems to get my director scenario running as needed/expected :(
My scenario:
I?d like to configure two dovecot backends, without the need for
multiple dovecot instances. Both backend servers are active/active and
act on top of a glusterfs storage, which implies the need for dovecot
director. As

I'm using dovecot in a multi server setup. Two directors forward pop3, imap and smtp to backend dovecots with their central storage on NFS.

Auth process sometimes stop responding after upgrade
Hi all;
I've upgraded a ring of dovecot directors from 2.2.15 to 2.2.36. After the
upgrade I've got some instability: a few time per day per server, seemly at
random, the auth process stop responding and the clients cannot authenticate
any more:

No failover from director to backend?
Hi everyone,
short version:
Is there no built in failover mechanism for the director service to
handle a backend failure?
Long version:
I have a frontend server running the director service and two backends.
Due to maintenance I had to shut down one of the backends which caused
connection errors for the users being directed to this backend.
I was very surprised as I expected the director to

Plugin hooks in login process
Hi all;
I've setup dovecot (2.1.10) in a cluster configuration. We have two servers
acting as frontend which authenticates users and proxy them to other two
servers which handles the "real" work.
Users credentials are on a mysql cluster; we have one master, in which
read/write queries are processed, and many replicated slave, which process
read-only queries.

connection to director (lmtp) time out
Hi all,
I'm running two directors with lmtp proxy as relay transport for my
mail exchangers.

Now, .3 is down and Postfix tries to deliver it to .4 but this

director ignoring director_mail_servers for lmtp connections
Hello,
Following Jan-Frode's advise I am trying this configuration:
{postfix} ---lmtp---> {director} ---lmtp---> {dovecot}
so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively.
whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

dovecot-proxy with managesieve, director and backend dovecot imap
hi all,
I've been tasked to add sieve/managesieve to an existing dovecot cluster
running 2.1.7 on debian wheezy which is made up of 2 dovecot-proxy hosts
as directors and some back end dovecot imap hosts all running the same
version.
My problem is that I thought to put the service on the director/proxy
hosts since they wouldn't have too much load on it, but when I do I get
