Dovecot, pigeonhole and hardlinks
by Gionatan Danti 03 Jan '20

03 Jan '20

Hi list, many moons ago I asked about preserving hardlink between identical messages when pigeonhole (for sieve filtering) was used. The reply was that, while hardlink worked well for non-filtered messages, using pigeonhole broke the hardlink (ie: some message-specific data was appended to the actual mail file). Here you can find the original thread: https://dovecot.org/pipermail/dovecot/2015-November/102579.html I would ask the same things today: is dovecot+pigeonhole capable of storing the same incoming message, sent to multiple rcpt or to a group/alias expanding in multiple recipients, as a single hardlink? Note: I know about SIS, but it has some important drawback and I would avoid using it.

spamsieve question
by Gerben Wierda 31 Dec '19

31 Dec '19

My new dovecot covers spam/ham training through the standard Spam_train and Notspam_train mailboxes. When a message is copied (I’m using macOS/iOS standard Apple clients) it triggers the spam/ham learning by rspamd. So far so good. When I move a message to Spam_train I’d like it to be removed immediately after learning. When I move a message to Notspam_train, I’d like it to move back where it came from after having been piped The first is I think doable, but how? Is the second doable?

Problem with big number of pop3-login [1 pre-login]
by Григорий Семенов 30 Dec '19

30 Dec '19

Dear all, I have recently migrated from my old Debian 8 (jessie) system to a new VM with fresh Debian 10 (buster) installation. Previous dovecot version was 2.2.13 and now I have 2.3.4.1. Dovecot was setup from Debian packages. Mostly, it is working, but one problem is just frustrating me. The number of some pop3-login processes are getting higher and higher until they reach my login_max_processes_count option which is equal 1000. From ps aux it looks like this: dovecot 55067 0.0 0.0 8192 6340 ? S 00:09 0:00 dovecot/pop3-login [1 pre-login] dovecot 55344 0.0 0.0 8192 6388 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55351 0.0 0.0 8192 6268 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55354 0.0 0.0 8192 6388 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55594 0.0 0.0 8192 6280 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] dovecot 56822 0.0 0.0 8192 6300 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] dovecot 56996 0.0 0.0 8192 6268 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] … Once it reaches the login_max_processes_count value my users start to complain to no new mail is arriving. Restart resolves the problem just for some time, until it will come to a limit next time (sometimes it take 1 day, sometimes 1 hour). In my old system I had nothing like that, but I guess it could be done something wrong during migration. I don’t know if it is significant but instead of real users I deal with only one third-party application which utilizeses 5 simultaneous tcp connections to check mailboxes via SSL\TLS. My dovecot is not public, and there is nothing else besides these 5 connections. Currently, in a config I have this: service pop3-login { process_min_avail = 4 process_limit = 4 client_limit = 100 service_count = 100 Please friends give me a way how to handle the situation. Might it be a bug? ========= Regards, Greg Semenov

Re: Issue running Dovecot in Docker Container

I'm not using internal logging. I'm running the docker with the logging to the host. I have used the same options you have specified. The problem is that the below processes are not running inside docker container whereas the standalone dovecot is running these processes(meaning without container) dovecot-Dovecot/auth dovecot-Dovecot/ssl-params dovecot-Director/lmtp dovecot-Director/ssl-params dovecot-Director/imap-login director Thanks & Regards, Naveen On Mon, Dec 30, 2019 at 3:16 PM Marc Roos <M.Roos(a)f1-outsourcing.eu> wrote: > > If you are running your container as root.

Issue running Dovecot in Docker Container
by Naveen Reddy 30 Dec '19

30 Dec '19

Hello, We need help with an issue that we are running into when we are trying to run Dovecot in Docker container. Also how do we enable debugging for dovecot. Logs doesn't show any info about the issue. Below processes are not running when a Director service is started: dovecot-Dovecot/auth dovecot-Dovecot/ssl-params dovecot-Director/lmtp dovecot-Director/ssl-params dovecot-Director/imap-login director Here is the version that I'm running and including the dovecot -n output below: bash-4.2# dovecot --version 2.2.36 bash-4.2# dovecot -n # 2.2.36 (xxxxx): /etc/dovecot/dovecot.conf # OS: Linux 4.1.12-112.14.11.el7uek.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.7 (Maipo) # Hostname: XXXXXXX auth_debug = yes auth_default_realm = xxxxxxxxxxxx auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = no hostname = xxxxxxxxxxxxxxxx instance_name = Dovecot login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c home=% domain=%d mail_debug = yes mail_fsync = always mail_gid = imapd mail_home = /xxxxxxxxxxx/%d/%n mail_location = dbox:~/ mail_uid = imapd mmap_disable = yes passdb { args = /etc/dovecot/lookups/ldap-pass.conf driver = ldap } passdb { args = /etc/dovecot/lookups/xxxx.conf driver = ldap } plugin { stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap lmtp service auth { client_limit = 4096 unix_listener auth-userdb { mode = 0777 } } service imap-login { chroot = login client_limit = 0 drop_priv_before_exec = no executable = imap-login extra_groups = group = idle_kill = 0 inet_listener imap { address = port = 1144 ssl = no } inet_listener imaps { address = port = 994 ssl = yes } privileged_group = process_limit = 0 process_min_avail = 0 protocol = imap service_count = 50 type = login user = $default_login_user vsz_limit = 18446744073709551615 B } service imap { service_count = 50 } service lmtp { executable = lmtp -L inet_listener lmtp { address = port = 10025 } } service stats { fifo_listener stats-mail { mode = 0600 user = imapd } } ssl_cert = </xxxxxxx/cert/dovecot.pem ssl_cipher_list = XXXXXX ssl_key = # hidden, use -P to show it ssl_protocols = XXXXX userdb { args = /etc/dovecot/lookups/ldap-user.conf driver = ldap } userdb { args = /etc/dovecot/lookups/xxxxxxx.conf driver = ldap } Thanks & Regards, Naveen

Using "doveadm pw" as unpriviledged user
by Ralf Jung 29 Dec '19

29 Dec '19

Hi all, Some time ago, I wrote a small CGI script to let users change their IMAP password. The script runs as www-data user and uses "doveadm pw" to check if a password hash matches a password. Unfortunately, this means that I have to make large parts of my dovecot config world-readable, as otherwise I get errors like this: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-auth.conf line 123: Couldn't open include file /etc/dovecot/conf.d/auth-sql.conf.ext: Permission denied I understand doveadm also does plenty of things that interact with the running dovecot instance and thus need access to the config, but for generating hashes or comparing hashes with passwords, it should not be necessary to read the dovecot config. This shouldn't require a properly setup dovecot on this machine at all, in fact. I'd prefer to make the config not world-readable, and indeed the Debian packaging sometimes makes those files not-world-readable on upgrades, breaking my setup. Is there any way to call "doveadm pw" as a users that cannot read the dovecot config on the current machine? This happens with the following versions of the dovecot debian package: 1:2.3.4.1-5+deb10u1~bpo9+1, 1:2.3.4.1-5+deb10u1 Thanks! Ralf PS: Please keep me in Cc, as I am not subscribed to the list.

Packages missing from repo
by Jon Geerars 29 Dec '19

29 Dec '19

Hi, Since a couple of weeks the Dovecot packages for Debian Jessie and Ubuntu Trusty have disappeared from the repo. According to https://repo.dovecot.org/ they should be in https://repo.dovecot.org/ce-2.3-latest/debian/jessie and https://repo.dovecot.org/ce-2.3-latest/ubuntu/trusty, but that leads to a 404. Where can I find them? Jon
