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

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.

Panic: file smtp-client-connection.c: line 1142 (smtp_client_connection_established)
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.
Yesterday I stumbled upon these log lines:

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

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:

socketpair failed: Too many open files on Debian 9
Hi @all,
after re-installing one of my two frontends/proxy-servers I get the
following error messages after some time (sometimes after 1h, sometimes

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?

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

Is Dovecot Director stable for production??
Today I will try Dovecot Director for a setup using a Cluster Backend with
GFS2 on rhel5, my question is if is Director stable for use in production
for large sites, I know is mainly designed for NFS but I believe it will do
the job also for a cluster filesystem like GFS2 and should solve the mail
persistence problem with a node and locking issues.
I plan to add a layer behind a load balancer to

New log entries with 2.0.19?
I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded
Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times)
disconnect in IDLE and inactivity time outs. I'm using only IMAP with
two users. Both users access the server from multiple devices, phone,
tablet and desktop computer. I had previously set the
max_userip_connections to 20 and rarely got the

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:

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

disable_plaintext_auth = no as no effect on IMAP/POP3 logins
Hello
In my installation the disable_plaintext_auth does not appear to take
effect.
I can see that the value is correct using doveconf -a but it doesn't
change anything.
Whenever attempting to log in using IMAP I get this:
* BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but
your client did it anyway. If anyone was listening, the password was
exposed.

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
