Help: Configuration example conversion from 2.3 to 2.4 ?
by ollie＠ik.me 13 Mar '25

13 Mar '25

Hello ! Like many people who are posting here, I'm a bit in "trouble" to convert my actual v2.3 config that is perfectly functional to the new v2.4 I've read the doc, searched on this list and everywhere I could find something among search engine results, and I still can't figure out how to solve my problem. The lack of examples right now is probably what is blocking me, so.. can anyone here with sharp knowledge of v2.4 configuration "translate" this official v2.3 example into a working v2.4 example ? ( ref: https://doc.dovecot.org/2.3/configuration_manual/quota/quota_dict/ ) Server-based Dictionaries -------------------------------------- plugin { # SQL backend: quota = dict:User quota::proxy::sqlquota # Redis backend (v2.1.9+): quota = dict:User quota::redis:host=127.0.0.1:prefix=user/ quota_rule = *:storage=10M:messages=1000 } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } ============================ Example dovecot-dict-sql.conf.ext: -------------------------------------------------- connect = host=localhost dbname=mails user=sqluser password=sqlpass map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Thanks a million times to whoever can do that ! :) Lon.

Bug: Logout counters reset after recreating hibernated process
by Eirik Rye 12 Mar '25

12 Mar '25

Hello, # dovecot --version 2.3.20 (80a5ac675d) When using hibernation (`imap_hibernate_timeout = 10s`), counters such as deleted/expunged messages, appear to be reset after the user process is recreated. Steps to reproduce: 1. Configure IMAP hibernation 2. Login with IMAP client 3. Delete+expunge a message 4. IDLE, and wait 10s for process to be hibernated 5. Unhibernate process (`DONE`), and log out 6. Observe the logged line: 2023-09-05T17:36:26+0200 imap(<redacted>)<776933><jA2nYJ4EPdcqAVtAAADwAAutur4AAAAB>: Info: Disconnected: Logged out in=9 out=88 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 The expected output is "deleted=1 expunged=1", not "deleted=0 expunged=0". If you follow the steps above, but skip the IDLE/hibernate step, the output is as expected. Interestingly, if the client is disconnected during hibernation (without recreating the process), the output from `imap-hibernate` is still as expected: 2023-09-05T17:45:15+0200 imap-hibernate(<redacted>)<770540><0qE0gJ4Emt8qAVtAAADwAAutur4AAAAB>: Info: Disconnected: Connection closed in=97 out=1020 deleted=1 expunged=1 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 This leads me to believe the counters are lost during process recreation, not during hibernation. This is an issue as customers will often come to us asking why messages have disappeared in their inbox, or asking for help to identify which client is expunging messages. Right now, this information is lost if hibernation is used and the client is hibernated after expunging. Best regards, Eirik Rye

SELinux blocking dovecot from writing to passwd.db
by jcalvert＠crystal3.com 11 Mar '25

11 Mar '25

Greetings, I'm running dovecot 2.3.21.1 (Plesk says up-to-date) on AlmaLinux 8.10, Plesk Obsidian 18.0.67 #3. I'm getting this repeated error in /var/log/messages... "SELinux is preventing /usr/libexec/dovecot/auth from write access on the file passwd.db." (I think passwd.db is the one in /var/lib/plesk/mail/auth/) This causes... "Activating via systemd: service name='org.fedoraproject.Setroubleshootd'" which is taking a lot of CPU. This error is happening continuously, about 1-3 times per minute. Am I correct in thinking that an email client or webmail client is trying to change an email account password via IMAP? If so, I would like to know how to disable this ability in dovecot. (I would like to change email account passwords only via Plesk.) If not, why is dovecot trying to write to the passwd.db file? The fact that SELinux is blocking this is concerning. thanks, JC

How to configure director
by akshay＠deeproot.in 11 Mar '25

11 Mar '25

Hi, I am testing instance with 1 director and 2 nodes. followed instructions in https://doc.dovecot.org/2.3/configuration_manual/director_settings/ but the authentication happens within the director server. Director does not forward connections to configured mail servers. LDAP is my user backend. How do i configure director ? Following is my director configuration # Director.conf director_servers = 10.22.13.164 director_mail_servers = 10.22.13.11 10.22.13.244 director_user_expire = 15 min service director { user = dovecot group = dovecot unix_listener login/director { mode = 0666 user = dovecot group = dovecot } fifo_listener login/proxy-notify { mode = 0666 } unix_listener director-userdb { mode = 0600 } inet_listener { port = 9090 } unix_listener director-admin { mode = 0666 } } service imap-login { executable = imap-login director #executable = director imap-login user = dovecot group = dovecot } service pop3-login { #executable = pop3-director } service submission-login { #executable = submission-login director } protocol lmtp { auth_socket_path = director-userdb } #### Thanks, Akshay

Hi. The Bat! email client does not display folder, it will appear as ' Example'. The email client technical support said quotation marks.

For additional modules, the mail_plugin_dir parameter is ignored
by Lafiel 10 Mar '25

10 Mar '25

Hi. The NixOS distribution for Dovecot uses a patch that hardcodes the path to the plugins in `/etc/dovecot/modules`. The modules themselves are located at `/nix/store/z9kf4ri8sq9f3r510qsm59g1n6kfc7q6-dovecot-2.3.21.1/lib/dovecot`, the script creates symlinks in the `/etc/dovecot/modules` directory. The additional modules are loaded normally. Now I want to remove the patch. I added the parameter `“--with-moduledir=$(out)/etc/dovecot/modules”`, and the modules are located at path `/nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules`. In the configuration I added the parameter `mail_plugin_dir = /etc/dovecot/modules`. The main modules load fine, but the optional modules don't want to load: ``` Error: Plugin 'imap_sieve' not found from directory /nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules ``` For additional modules, the mail_plugin_dir parameter is ignored. Temporary solution - in src/config/config-parser.h file I replaced the line ``` #define CONFIG_MODULE_DIR MODULEDIR"/settings” ``` by ``` #define CONFIG_MODULE_DIR “/etc/dovecot/modules/settings” ``` -- Best regards, Lafiel mailto:lafiel@elven.pw

Questions about fts_flatcurve in Dovecot 2.4
by Andrea Gabellini 10 Mar '25

10 Mar '25

Hi, I'm testing the fts_flatcurve plugin on Dovecot 2.4. This is my first time using an FTS plugin, and I have a few questions. Below is the configuration I am referring to. - Does the language_filters setting apply by default when a language xx {} section is defined? - If so, within a language section where a filter is declared, should I set filter_name = no to remove it? - The documentation includes this warning: "Using stopwords with multiple languages configured WILL cause some searches to fail. The recommended solution is to NOT use the stopword filter when multiple languages are present in the configuration." Does this mean it's best to avoid the stopwords filter entirely, or can it still be used for at least one language? - Does the attached configuration make sense? :-) language_filters { lowercase = yes normalizer-icu = yes snowball = yes } language it { default = yes filters { lowercase = yes normalizer-icu = yes snowball = yes stopwords = yes } } language en { } language de { } language es { } language fr { filters { lowercase = yes normalizer-icu = yes snowball = yes contractions = yes } } Thanks in advance for your support!

I tried to make a pull request for my changes but got stalled on figuring out how to reference my repository in the github GUI. Do I need to download their custom CLI tools to do it?
