Mail not getting deleted physically
by Support Team 19 Sep '25

19 Sep '25

I am clearing the mail using roundcube and also deleting mail from trash and thus permenently deleting the mail. The mail quota changes. But mail is still present in INBOX.EXPUNGED.Trash and also with refcount 1. The physical disk usage remains the same and purge not deleting the mail physically, prob due to refcount. 1.

fts_flatcurve max_term_size config missing or broken in v2.4
by publists＠emailgroups.net 17 Sep '25

17 Sep '25

Hi, I'm working on migrating my v2.3 -> v2.4 configuration. From my 2.3 config I have ... fts flatcurve { commit_limit = 2000 29 max_term_size = 60 min_term_size = 3 substring_search = yes } ... From reading the current docs' "Configuration Example" https://doc.dovecot.org/2.4.1/core/plugins/fts_flatcurve.html#configuration… that looks OK for v2.4.1 too. But a config check fails, doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/50-fts.conf line 29: max_term_size: Unknown setting: max_term_size (fts_max_term_size or fts_flatcurve_max_term_size not found either.) There's no mention of "max_term_size" in https://doc.dovecot.org/2.4.1/installation/upgrade/2.3-to-2.4.html as a change. It's also NOT listed as a current setting at https://doc.dovecot.org/2.4.1/core/summaries/settings.html Checking in code sources cd dovecot git checkout release-2.4.1 Switched to branch 'release-2.4.1' Your branch is up to date with 'origin/release-2.4.1'. "min_term_size" is in use grep "min_term_size" * fts-backend-flatcurve.c: if (size < ctx->backend->fuser->set->min_term_size) fts-backend-flatcurve-xapian.cc: * smaller than min_term_size. Requires libicu in order to correctly handle fts-backend-flatcurve-xapian.cc: if (len < fuser->set->min_term_size) fts-backend-flatcurve-xapian.cc: if (len < fuser->set->min_term_size) fts-flatcurve-settings.c: DEF(UINT, min_term_size), fts-flatcurve-settings.c: .min_term_size = 2, fts-flatcurve-settings.h: unsigned int min_term_size; But no trace of "max_term_size" at all from grep "max_term_size" * Is "max_term_size" still valid config? Does code or documentation, or both, need to change? Or am I misreading the usage? Thanks, Dave

hidden / alias_for / sieve
by Erick Calder 12 Sep '25

hi. I'm running on Fedora 42 and want to hide the Deleted Messages folder (because I want to use Trash instead). unfortunately this fails: mailbox "Deleted Messages" { hidden = yes } which I understand depends on the "mailbox" plugin. however, when I look in /var/lib64/dovecot, I don't see any such plugin. I also cannot find in the repositories any RPM that provides it. I understand it may be baked into the core binary but if so, enabling it should work, and yet if I do enable it, I get the error below: Sep 11 10:06:01 mail dovecot[739762]: imap(ekkis): Error: Plugin 'mailbox' not found from directory /usr/lib64/dovecot I would also like to use the alias_for but that also fails. sigh.

Does dovecot LMTP can process SMTPUTF8 emails? I guess not, but I want to confirm. KJ -- http://wolnelektury.pl/wesprzyj/teraz/ <kira> is a surgical war where you go give the foreign troops nose jobs?

Sieve Scripts via SQL Dicts in Dovecot 2.4 not working?
by Niklas Meyer 11 Sep '25

11 Sep '25

Hello everyone, I am currently working on porting the Dovecot 2.4 configuration from the latest 2.3 version. During this process, I encountered issues with the Sieve filters, particularly those related to SQL dict mappings. The previous (2.3) configuration looked like this and worked: |map { pattern = priv/sieve/name/$script_nametable = sieve_before username_field = username value_field = idfields { script_name = $script_name} } map { pattern = priv/sieve/data/$idtable = sieve_before username_field = username value_field = script_data fields { id= $id} } | This resulted in the following SQL queries on the MySQL server: |2025-08-1511:01:29.237511SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:01:29.236416SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'| As you can see, there are SQL mappings for |sieve_before| and |sieve_after|, alongside a local file loaded prior to the SQL settings, as they are user-based. In Dovecot 2.3, everything worked and the scripts were executed. In 2.4, however, they no longer run. I adapted the configuration for dict SQL mapping for Sieve filters according to the documentation: |dict_mappriv/sieve/name/$script_name{ sql_table= sieve_before username_field = username value_field id { } # The script name field in the table to querykey_fieldscript_name { value= $script_name} } dict_map priv/sieve/data/$id{ sql_table= sieve_before username_field = username value_field script_data { } key_fieldid { value= $id} } | This also results in the dict proxy querying the database with the same pattern as before: |2025-08-1511:11:47.175184SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.172952SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.155786SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.136030SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'| However, unlike in 2.3, it now queries the DB twice.

Here are the current Sieve script declarations: sieve_script before { type = before driver = file path = /var/vmail/sieve/global_sieve_before.sieve } sieve_script before2 { type = before driver = dict name = active dict proxy { name = sieve_before sieve_script_bin_path = /var/vmail/sieve_before_bindir } } sieve_script after { type = after driver = file path = /var/vmail/sieve/global_sieve_after.sieve } sieve_script after2 { type = after driver = dict name = active dict proxy { name = sieve_after sieve_script_bin_path = /var/vmail/sieve_after_bindir } } # Personal scripts sieve_script personal { type = personal driver = file path = ~/sieve active_path = ~/.dovecot.sieve } The dict proxy configuration, pointing to the dict_map SQL query above, looks like this: dict sieve_after { driver = sql !include /etc/dovecot/sql/dovecot-dict-sql-sieve_after.conf } dict sieve_before { driver = sql !include /etc/dovecot/sql/dovecot-dict-sql-sieve_before.conf } Thanks for your guidance.

Sample with spool file: .mbsyncrc, Isync, Information Lifecycle Management, dovecot, GMail, IMAP
by Philip Bondi 10 Sep '25

10 Sep '25

Hello to all: I wanted to offer my working .mbsyncrc to the community. I also have a spool file to share. In my opinion, 15 Gb on our Google accounts is no longer enough. Google Photos keeps prompting to enable backup. Most people are going to exceed this quota. In my opinion, this is manifestation of serious "platform decay". This is starting to affect all my immediate family members. In my opinion, one should have methodology to move GMail away of Google for Information Lifecycle Management. To achieve, I have setup Debian 12 virtual machine on QNAP running Dovecot. This setup is beyond the scope of this article. I setup Isync to sync gmail to my Debian 12 virtual machine. Then I wrote a script to move the gmail to local mbox. Isync will then purge the email from Gmail. https://www.snbforums.com/threads/sample-with-spool-file-mbsyncrc-isync-inf…

Hi! Due to algorithm limitations, we have signed the RHEL8 packages for 2.4.1 with Dovecot 2.3 signing key. This should make it verifiable on RHEL8. Regards, Aki Tuomi Open-Xchange oy

RHEL 8 key import error
by Gioele Pannetto 08 Sep '25

08 Sep '25

Hi, I'm having issues while installing Dovecot 2.4 on a Rocky Linux 8.10 server. This server was running Dovecot 2.3 but I wanted to upgrade it to 2.4. This is my repo file: [dovecot-2.4-latest] name=Dovecot 2.4 RHEL $releasever - $basearch baseurl=https://repo.dovecot.org/ce-2.4-latest/rhel/$releasever/RPMS/$basea… gpgkey=https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4 gpgcheck=1 enabled=1 When I run dnf update I get a GPG error: Problem opening package dovecot-2.4.1-4.x86_64.rpm Problem opening package dovecot-lua-2.4.1-4.x86_64.rpm Problem opening package dovecot-mysql-2.4.1-4.x86_64.rpm The downloaded packages were saved in cache until the next successful transaction. You can remove cached packages by executing 'dnf clean packages'. Error: GPG check FAILED If I try to import the key manually with rpm --import https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4 I get: error: https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4: key 1 import failed. I also tried it on a fresh Rocky Linux 8.10 installation and I get the same exact error, but running it on Rocky Linux 9.6 works just fine. This is my gpg --version on RHEL 8.10: gpg (GnuPG) 2.2.20 libgcrypt 1.8.5 Copyright (C) 2020 Free Software Foundation, Inc.

Is it possible to use literal %2F inside a dovecot.http.client request url?
by hmmmz1000＠gmail.com 07 Sep '25

07 Sep '25

Hello, I'm using dovecot (2.3) lua with dovecot.http.client but I need the request url to have an url encoded slash (/) as %2F (or %2f) but if I enter for example https://test.com/%2F/test it looks like it changes it to a slash (https://test.com///test) in the http debug log (also the request fails as it's not %2F). I've also tried with %252F to encode the % but that doesn't change at all (keeps being %252F) & also tried with %%2F and \%2F but that gets the errors "Expecting hex digit after '%', but found '%'" for %%2F and "invalid escape sequence" for \%2F. Does anyone have an idea how to solve this or if it's even possible?
