Dovecot calculating quota wrong or am I stupid?
by jarland＠mxroute.com 20 May '24

20 May '24

I'm currently running 2.3.21 on this system and here's what I'm seeing (a bit cut down for excess): # doveadm quota get -u emailuser(a)domain.net STORAGE 1052385 MESSAGE 2741 So the storage is roughly more than 1GB according to Dovecot. No change after quota recalc. But: root@arrow:/home/username/imap/domain.net# du -sh emailuser 692M emailuser There are no symlinks or anything like that. Quota config is pretty basic: root@arrow:/etc/dovecot# cat conf.d/90-quota.conf #add quota to end of line in: #/etc/dovecot/conf/mail_plugins.conf, eg: #mail_plugins = $mail_plugins quota #add imap_quota to end of line in: #/etc/dovecot/conf/imap_mail_plugins.conf, eg: #mail_plugins = $mail_plugins imap_quota plugin { quota = maildir } If anyone has advice I would greatly appreciate it.

After user disconnect run the custom script
by Alexey Krylov 20 May '24

20 May '24

Sirs, good day. Please, send me the link, where I can find the info about configuring firing script after dovecot client is disconnected. I found post-login scripting. Than's cool, but... I need to fire script a little bit later. May be I try to build crutches... But I wish with all my heart to do this. Thanks to everyone who responded. -- Это сообщение было проверено антивирусным ПО Avast на наличие вирусов. www.avast.com

Change the default base_dir to /run from ${prefix}/var/run
by Дилян Палаузов 20 May '24

20 May '24

Hello, at 6b1bcf1bad1d7, calling ./configure && make install sets prefix=/usr/local, and thus the default base_dir = /usr/local/var/run/dovecot. Moreover it installs /usr/lib/systemd/system/dovecot.service with [Service] ProtectSystem=full. ProtectSystem=full mounts /usr as read-only, so no files can be written under the default base_dir. The Linux Hierachy Standard says for /usr/local - https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s09.html - directories bin, etc, games, include, lib, man, sbin, share, and src must be in /usr/local. No other directories, except those listed below, may be in /usr/local after first installing a FHS-compliant system. var is not listed below. (“below” means the citation above, not the next paragraph) For /var/run LSH contains - https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html#varrunRuntimeVari… - This directory was once intended for system information data describing the system since it was booted. These functions have been moved to /run; this directory exists to ensure compatibility with systems and software using an older version of this specification. In general, the requirements for /run shall also apply to /var/run. It is valid to implement /var/run as a symlink to /run. . For /run LHS mentions “This directory contains system information data describing the system since it was booted. Files under this directory must be cleared (removed or truncated as appropriate) at the beginning of the boot process.” The defaults base_dir=/usr/local/var/run/dovecot and ProtectSystem=full present a non-working configuration. • Please consider changing the default (implicit) value of base_dir to /run. • When prefix is /usr/local, then dovecot.service should be installed in /usr/local/lib/systemd/system/. Kind regards Дилян

example/config misses required section names for passdb{} and userdb{}
by Дилян Палаузов 20 May '24

20 May '24

Hello, I installed Dovecot from git 6b1bcf1bad1d78e, copied /usr/local/share/doc/dovecot/example/config to /usr/local/etc/dovecot and called dovecot -F . The system reported doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext line 11: passdb { } is missing section name The problem remains, if I delete dovecot-dict-auth.conf.ext dovecot-ldap.conf.ext dovecot-oauth2.conf.ext dovecot-sql.conf.ext conf.d/auth-deny.conf.ext conf.d/auth-ldap.conf.ext conf.d/auth-passwdfile.conf.ext conf.d/auth-static.conf.ext conf.d/auth-dict.conf.ext conf.d/auth-master.conf.ext conf.d/auth-sql.conf.ext thus leaving passdb {} and userdb {} defined on a single place. Indeed, auth-system.conf.ext contains the sections passdb and userdb without the optional name, as described at https://doc.dovecot.org/configuration_manual/config_file/#sections . The problem report is that the example configuration does not contain for sections userdb and passdb a section name, and at the same time the as optional described section name is mandatory in Dovecot on these places. Kind regards Dilyan

Dovecot logging to files causes issues
by Richard Rosner 19 May '24

19 May '24

I have a mailing server setup based on Debian Stable that uses postfix (v3.7.10) for SMTP and dovecot (v2.3.19.1 (9b53102964)) for IMAP. I now wanted to set dovecot to not write to syslog, but to dedicated files in /var/log/dovecot. While everything indicates that this happens successfully as the log files gain in size, I also get lots of these errors: May 13 20:55:37 mail postfix/local[2824184]: 95BCF1000A9: to=<user(a)domain.de>, relay=local, delay=3.2, delays=1.9/0.29/0/1.1, dsn=4.3.0, status=deferred (temporary failure. Command output: lda(user): Error: net_connect_unix(/run/dovecot/stats-writer) failed: Permission denied Can't open log file /var/log/dovecot/error.log: Permission denied ) If it would only log the complaints I wouldn't worry, but as long as I don't revert the changes in dovecot's config, mail receiving is at least vastly delayed, most likely stuck alltogether. So how am I supposed to set these settings? I've chainged these settings in /etc/dovecot/conf.d/10-logging.conf: log_path = /var/log/dovecot/error.log debug_log_path = /var/log/dovecot/debug.log log_debug = category=error The whole directory /var/log/dovecot is owned by dovecot:dovecot, permissions on debug.log, error.log and info.log are 644.

Re: Failing to archive many messages
by Francis Augusto Medeiros-Logeay 18 May '24

Today I realized that it was indeed the sa-learn that is slowing down my Archiving. I added an «&» on the end of the line that calls the sa-learn (called by the report-ham.sieve script): exec /usr/bin/sa-learn -u ${1} --ham & Does anyone thing this is a bad idea? I noticed that archiving got way faster this way… Best, Francis > On 9 May 2024, at 23:09, dovecot-request(a)dovecot.org wrote: > >> On 9 May 2024, at 19:45, dovecot-request(a)dovecot.org <mailto:dovecot-request@dovecot.org> wrote: >> >> Francis Augusto Medeiros-Logeay via dovecot skrev den 2024-05-09 12:29: >> >>>> If you want to analyze emails, why not do it with scheduled crons >>>> after they are archived? >> >> maybe ask for skip older then one day in here >> https://github.com/isbg/isbg/tree/master >> >> while roundcube just set the needed flag for retest ? >> >>> wouldn't it reanalyze all archived messages anyway? >> >> sometimes email is ham at recpt stage, while its spam later on test, >> this is why isbg is made imho :) > > > I see. > > But I wonder if there is something wrong with what I already have. It worked fine for years, and it works fine for most of my users. I tested with a few accounts, and Archving (with its sa-learn script) works blazingly fast. But with one user - happens to be mine - it is super slow when archiving, most likely due the sa-learn. > > Best, > > Francis

Sieve extprograms pipe :try cancels implicit keep
by Sebastiaan Hoogeveen 17 May '24

17 May '24

Hi, When using the :try tag on the pipe command in the sieve_extprograms plugin Sieve’s implicit keep is cancelled if the executed command fails. The specification on https://raw.githubusercontent.com/dovecot/pigeonhole/master/doc/rfc/spec-bo… states: “When the ":try" tag is specified, the "pipe" instruction will attempt execution of the external program, but failure will not cause the whole Sieve script execution to fail with an error. Instead, the Sieve processing continues as if the "pipe" action was never triggered." However, using the :try tag marks the pip command as successful even if it fails and because pipe is a disposition-type action the implicit keep is cancelled, resulting in the piped message being discarded. If this is the intended behaviour then I would suggest amending the text of the specification to: “When the ":try" tag is specified, the "pipe" instruction will attempt execution of the external program, but failure will not cause the whole Sieve script execution to fail with an error. Instead, the Sieve processing continues as if the "pipe" action was executed successfully and cancel implicit keep.” If this is not the intended behaviour then please consider this a bug report, with my apologies for not adding a patch (it seems to be a bit more complex than just changing the return value of act_pipe_commit). Kind regards, -- Sebastiaan Hoogeveen NederHost https://www.nederhost.nl/ KvK: 34099781
