Hi, I have a timeout problem only when I have heavy load in my system. I have two director servers directing to 4 backend servers. The problem is when my smtp relays tries to deliver mail to my users via lmtp (proxied with director). In the smtp logs I have: Jun 12 11:41:18 xenon13 postfix/lmtp[4248]: 4433E5D5A0: to=<myuser at um.es>, relay=pop.um.es[155.54.212.106]:24, delay=31,

Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164. The problem is that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the

Hello, I've been using dovecot for a long time, but now I'm having troubles with I change I need to make. I have a director server in front of two backend servers. All of these servers are running dovecot 2.1.16. Redirection to backend servers are based in an attribute of a ldap server. My users are defined in this same ldap server.

Hello, I have configured director in front of dovecot imap/pop/lmtp servers. When I need to manipulate a user mailbox, I use doveadm commands at director server's, with -S option. But some commands return exit code 139 when command returns more than 40 entries (I think). For example, the command: sudo doveadm fetch -u amateo hdr mailbox Trash HEADER Subject "nyctalus11/"

Hello, I am trying to configure director as described at http://wiki2.dovecot.org/Director. I have previously tried the proxy and it worked.

Hello, I have configured two dovecot servers with director acting as lmtp/imap/pop proxy server with 8 dovecot backend servers.

Hi, I've been reading doc at http://wiki2.dovecot.org/Director to configure my servers. My question is regarding configuration of doveadm server. I have configured both, director and backend servers, as described in that doc, but I don't know how to run doveadm commands in director servers. doveadm is working, because I can run commands, but they are executed in local (director)

Hi, What is the real difference between client and process limit? According to documentation (http://wiki2.dovecot.org/Services#Service_limits): client_limit: Maximum number of simultaneous client connections. If set to 0, default_client_limit is used instead. process_limit: Maximum number of processes that can exist for this service. If set to 0, default_process_limit is used instead. But

Hi, I have a director farm running in front of dovecot pop/imap servers. For a reason, one of my backend servers have been down, so poolmon disables it in director servers and users corresponding to it has been sent to other servers. Until this, no problem. Now my failed backend server is up again, and I want to redirect all of its users to it, without waiting for it director sessions to

Hello, I continue debugging my problems with my update to dovecot 2.x :-( I have dovecot 2.0.13 running in ubuntu 10.04 (lucid) x64. My users are in a ldap directory.

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41

Hi, I'm having problems with director and lmtp for delivering messages to my dovecot farm.

Hello, I'm configuring lazy expunge plugin to act as a kind of backup of my user's emails. I'm getting a little problem because a lot of my users use "move to trash" behaviour in their email client (most of them are using thunderbird which has no option to hide deleted messages and is a hassle working with mark as deleted with it). The problem combining move to trash

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap

Hello, I'm trying to configure dovecot (2.0.13) to cache user and pass dbs. This a mail server whose purpose is only to deliver messages through dovecot lda. My users are in a ldap server.

Hi, I'm configuring a farm of dovecot proxies redirecting users to backend servers. The decision of which backend server is used for a user is based in its ldap account information. In my previous configuration I was using an inherited director configuration in these proxy servers, but now I was wondering that because the decision is made according to user information, I don't need

We don't warrant that a user is always directed to the same server, although our load balancer sends all request from one IP to the same server (during a session time with a inactivity timeout). This is

Hello, I'm trying to configure lazy_expunge plugin (as a way to provide easy backup for mails).

Hello, I am configuring quota plugin per user, not for the whole system.

I'm using a passwd-file in the way:
