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.

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

How to disable Director service?
Hi All,
Does anyone know how to disable the Director service. In our current
running Dovecot 2.2.4, if the director configuration is commented out
and Dovecot has no errors nor warnings. But the version 2.2.12 I'm
testing with gives out fatal errors. We have dedicated Dovecot Director
servers that serve the public frontend and separate dedicated imap/pop3
servers on the backend

Ring SYNC appears to have got lost, resending after upgrade
Hi @all,
on Saturday I upgraded two dovecot servers from squeeze to wheezy and
dovecot from 2.1.x to 2.2.5 (compiled from sources). After the upgrade
everything worked fine at first.
On Sunday Morning I recognized these errors (they occured after a reload
for logging purpose on midnight) on one server:

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

Can we retrieve Dovecot Proxys 'hostName' from Director instead of LDAP?
We have a Dovecot installation of several nodes that share an NFS mount for
the user data. We are trying to configure Dovecot Proxy with Director in
order to have Director select the appropriate IMAP server for a given user
on behave of Dovecot Proxy. So far all examples I've seen on the dovecot
site require the proxy to know the exact mail server to pass the user to by
way of an LDAP

Problem with running two dovecot instances on the same server
Hello All,
Have anyone met the problem I am struggling with at the moment ?
The problem is when I run two instances of dovecot 2.1.8 which are one
for proxy-director and another one is a regular one on the same server
then I have big amount of strange entries in the /var/log/mail.err:
Jul 26 11:51:20 dovecot-test-1 dovecot: director: Error: Empty server list

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:

after re-installing one of my two frontends/proxy-servers I get the

I haven't done this on the old, working machine.
So there must be a difference between Debian 7 and 9 how open files are
handled?

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

random, the auth process stop responding and the clients cannot authenticate
any more:

dovecot director terminate ssl ?
I plan on putting two dovecot directors in front of our backend dovecot
pop/imap servers, instead of our current haproxy loadbalancing of the
connections -- but how do we handle SSL in such a setup. Will all SSL be
terminated on the directors automatically, and then proxyed plain text,
or is there any configuration needed to achieve this ?
Does it matter that the directors are v2.0 while the

director map and mysql
hello!
Is "doveadm director map" command suppose to work when I store "host" value in mysql table?
It gives me nothing in output with no errors in log.
I've successfully setup directors with static passdb, and decided to give a try setup with storing host value in mysql table.
The proxying is actually working, I'm just unhappy with no output from "doveadm
