Hi, I'm working for tuning a busy cluster of dovecot servers. Heach server as 4 core, 8GB of RAM and provide POP3 and IMAP access to mailbox. OS is Debian 6.0 and dovecot version is 1.2.15. I am unsure how to set "login_max_processes_count" and "login_max_connections" for reach the best situation when login_process_per_connection is set to no. I don't know what

Greetings to all I need a masteruser/proxy account for some applications to be implemented and i am having some problems. Normal users are proxyied through ldap queries to the remote machine and this is working like it sopose to, but i can't make the master user to work. Below are both the dovecot.conf and dovecot-ldap.conf and verbose logs on the proxy machine. If i log directly on the

Hi, i don't know. Is normal login_max_processes_count > 1024?? Our environment is about 1700 users (imaps + thunderbird or imaps+horde). The server is RedHat Enterprise Linux 5.2 User logins different in a hour: # cat dovecot.info | grep 'Nov 11 10' | grep "login: Login" | cut -d'<' -f2 | cut -d'>' -f1 | sort | uniq | wc -l 685 Logins in a hour:

Hello Timo, I just tried the master user feature with a very simple setup (Dovecot v2.2.15) : !include auth-master.conf.ext -> passwd-file passdb !include auth-ldap.conf.ext -> ldap passdb (userdb prefetched) without auth_bind=yes without pass=yes I get this userdb lookup error : dovecot: auth: passwd-file(masteruser,157.99.64.42,master,<4Pgesh0OygCdY0Aq>): Master user logging in

Hello Timo, I just launched rc1 with auth_verbose = yes auth_debug = yes #auth_debug_passwords = no and on a wrong password, I see my crypted passwd in the log : userPassword(password)={Crypt}xxxxxxxx Is that normal, since I assume that auth_debug_passwords defaults to no ? -- Thomas Hummel | Institut Pasteur <hummel at pasteur.fr> | P?le informatique - syst?mes et r?seau

Hi all. I'm trying to install Dovecot 1.1.rc13 on Cygwin. I've read the related posts, and I realize that maybe there's no solution at present; since I'm having a different error, though, I'm posting it here. Compilation succeeds. Starting dovecot from command line results in: Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640). Either

Hello Timo, I've got some questions about dovecot-auth processes which I cannot answer just by reading the doc : [ Note : my problem is that I often see dovecot: pop3-login: Can't connect to auth server at default: Connection refused and I'm looking for a way to tweak dovecot.conf parameters to allow more login <-> auth connections ] - I'm not sure I get the auth

hi, I've used dovecot 1.1.16 but after upgrade to dovecot 1.2.4 per-user ldap quotas stoped working.

Hi, I'm using dovecot-1.0.0 on gentoo box and I have problem with authentication using digest-md5 and passwords stored as plain text in ldap database, when I use cram-md5 it works, while digest-md5 give this error (squirrelmail login): May 5 16:03:32 srv dovecot: auth(default): client in: AUTH 1 DIGEST-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 May 5

Hi, Thank you for pointing me about -xc99 flag, I have compiled and installed dovecot inplace of version 1.0.5 without any special actions on the upgrade. And after starting it immediately got in it's log file messages like: --- dovecot: Oct 16 23:10:18 Error: IMAP(seriv): file_set_size() failed with index cache file /var/spool/imap/seriv/.imap/.git-altlinux-ru/dovecot.index.cache: Invalid

I think today just due to increased use, my mail servers hit login_max_processes_count. It wasn't obvious what was happening, logins just weren't acting like they should and sometimes would get disconnected before given a prompt from the server. Something made me think to check if I had too many of certain dovecot processes and I found I had 128 imap-login processes on both servers,

Hi All, Is there a way to define the number for imap-login processes and pop3-login processes separately? My mail server is getting more IMAP clients and much less POP3 clients these days and it continues to run out of authentication processes. I have been increasing login_max_processes_count the last couple of days and I noticed that it's split between IMAP and POP3. All 129 imap-login

I'm getting "Maximum number of mail processes exceeded" messages when 512 imap Processes are active. Dovecot reports: Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1712). Either grow the limit or change login_max_processes_count and max_mail_processes settings But in my /var/service/dovecot/run script I use: #!/bin/sh mkdir /var/core chmod

Hello, I've unfortunately been unable to find anything relating to the problem I'm having specifically, in searching the list or google, and so I now plead to you to assistance. I'm running Dovecot as an LDA and SASL auth for Postfix on a Debian 4 box. Dovecot is version 1.0.rc15 (the official debian pkg version). The problem I'm running into is this. After some time of

Hello, I'm using dovecot version 1.0.13 on reiserfs on hardware RAID-0, but I'm getting the following error in the logs every time one user tries to access his old mails in the .Sent directory: dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file /var/mail/Maildir/marek.chajecki/.Sent/dovecot-uidlist As a result he fails to get access to the emails in this

Hello Timo, I'm trying to configure dovecot-2.1.15 master correctly regarding imap-login limits. I want to use service_count=0 and I'm starting with something like this : #default_process_limit = 100 #default_client_limit = 1000 service imap-login { [...] service_count = 0 process_min_avail = 8 vsz_limit = 1024M } -> Does it make sense to set a process_limit if

Hi all I am trying to set up an email Server with a Samba4 AD as user Directory. Does anybody know a good how-to to setup user auth against AD ? Or could anyone tell me how to do it? I am having an email Server up and running with openldap but want to change to Samba4 AD, because of the openchange Integration. I would appreciate any help on this topic. -- Mit freundlichem Gru?

Hello Timo, I'm curious about 2 points (I'm using alpha2 but these are general questions) : Background : . I connect to dovecot-1.0.alpha2 through thunderbird . I use ldap pass/userdb and PLAIN mech . I've only got one auth block in dovecot.conf (all pass/userdb/mech except ldap/PLAIN are commented) 1) I notice that, for one thunderbird connection trial, imap-login

Hi Timo, just to report that . dovecot-1.2.12 which ran fine for several month . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC amd64) . using Maildir (mailboxes, control and indexes on NFS) has crashed this morning on our server. I found nothing special in the logfile. Attached are dovecot -n output and a gdb backtrace of the core file. Thanks -- Thomas Hummel | Institut

Hi all, Our Dovecot server became non-responsive today and had to be restarted. We had approximately 1200 imap sessions running, and when I looked at the log, I found the following errors: Jan 16 10:02:01 lamar dovecot: imap-login: Disconnected: Connection queue full: rip=75.166.40.150, lip=129.82.103.75, TLS handshake Jan 16 10:02:01 lamar dovecot: imap-login: Disconnected: Connection queue
