'duplicate listener' on port 465
by William David Edwards 17 Aug '25

17 Aug '25

Hi, When configuring SMTPS as described on https://doc.dovecot.org/main/core/config/submission.html#smtps, Dovecot says there is a 'duplicate listener'. MRE: ``` root@dovecot24-test:/etc/dovecot/conf.d# doveconf -n # 2.4.1-4+debian12 (7d8c0e5759): /etc/dovecot/dovecot.conf # Pigeonhole version 2.4.1-4+debian12 (0a86619f) # OS: Linux 6.1.0-29-amd64 x86_64 Debian 12.11 # Hostname: dovecot24-test.cyberfusion.nl # 4 default setting changes since version 2.4.0 dovecot_config_version = 2.4.0 dovecot_storage_version = 2.4.0 protocols = submission service submission-login { inet_listener submission_465 { port = 465 } } doveconf: Error: duplicate listener: 465:* doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: duplicate listener: 465:* ``` Can anyone help me understand why this listener would be 'duplicate'? This setup worked on 2.3.21.1. Thanks! William David Edwards

[Patch] Allow sieve redirects to specified domains only
by Kadlecsik József 10 Aug '25

10 Aug '25

Hello, The use case is simple: we have to forbid sieve redirects to outside, but should be able to redirect inside. The patch below adds a new sieve configuration option sieve_allowed_redirects to list the domains to which redirects are permitted and otherwise are not allowed. Please consider it. diff --git a/pigeonhole/doc/example-config/conf.d/90-sieve.conf b/pigeonhole/doc/example-config/conf.d/90-sieve.conf index 238bcf4..3b4ac65 100644 --- a/pigeonhole/doc/example-config/conf.d/90-sieve.conf +++ b/pigeonhole/doc/example-config/conf.d/90-sieve.conf @@ -126,6 +126,10 @@ plugin { # script execution.

sieve script is not exescuted
by Kamil Jońca 30 Jul '25

30 Jul '25

I have scripts in 2 places: sieve_script personal { path = ~/.dovecot.sieve } sieve_script before { path = /etc/dovecot/sieve } /etc/dovecot/sieve is directory with (currently) one script. This script add header to message. And it seems, that "before" script is not executed. Any hints? KJ -- http://wolnelektury.pl/wesprzyj/teraz/ "Linux: the operating system with a CLUE...

"lock/disable" user's mailbox
by roughnecks 29 Jul '25

29 Jul '25

Hello, not sure if relevant here, but I'm in need of disabling or locking down an user's mailbox, without completely removing the related system account. It would be nice if said account was not able to receive emails anymore, or "better", until it was re-enabled. Would also be cool if the sender received a warning back, upon the failed dispatch. Does that even make sense? :D I'm running postfix and dovecot on a debian bookworm VPS. Thanks -- roughnecks

When does dovecot use sendmail_path?
by Joseph Tam 29 Jul '25

29 Jul '25

I'm trying to plug up all the holes where local mail leaves our mail system without a DKIM signature. One avenue is bounce messages. I wrote a small sendmail wrapper to add DKIM signatures, and defined it as the value for dovecot's sendmail_path. I presume Dovecot invokes this executable when it has to send a send message. Under what circumstances does this happen? I tried to provoke a mailout by sending messages to recipients with full quotas and permission locked mailbox files, but could not generate any mail back.

Hi, are there anywhere recommendations or 'best practices' for compiling dovecot-2.4.x at IBMs AIX7.3? With some own patches i can compile it, but one unexpected result is # /usr/local/bin/doveadm mailbox list -u <user> /usr/local/bin/doveconf: invalid option -- u What's wrong? -- Mit freundlichen Grüßen / Best regards / Salutations / Cordialmente ___________________________________________________________________ Brandenburgische Technische Universität Cottbus – Senftenberg E Andreas.Kossack(a)B-TU.De

one-off doveadm commands broken in 2.4.1 when using docker
by jlh 28 Jul '25

Hi all In 2.3, I could use doveadm from the docker image as a standalone tool, but this no longer works in 2.4: $ docker run --rm -ti dovecot/dovecot:2.3-latest doveadm usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A] [-S <socket_path>] [-r] <search query> [...snip...] $ docker run --rm -ti dovecot/dovecot:latest-2.4 doveadm doveconf: Fatal: Cannot expand variable %{env:USER_PASSWORD This was useful for hashing passwords with "doveadm pw". I assume this wasn't an intentional change in how doveadm works. For now I'll just use the old image when hashing passwords. Thank you! Jean-Luc

siebe settings in 2.4.0
by Helmut K. C. Tessarek 23 Jul '25

I've been reading the docs and the migration docs for hours, but the sieve config is a mess. In 2.3.x I am using: plugin { sieve = ~/.sieve sieve_dir = ~/.sieve_storage } and this is how it looks in my home dir: $ ls -la .sie* lrwxrwxrwx 32 a b c d .sieve -> .sieve_storage/MailFilters.sieve .rw------- 0 a b c d .sieve.log .rw------- 17,414 a b c d 2025-07-08 03:00 .sieve.svbin So How do I do the same in 2.4.x? I've come so far as: sieve_script personal { driver = file } But then there are path, bin_path, active_path, name, and a bunch of other settings. Sorry to be a little bit frustrated, but my old settings are not out of the ordinary (2 freaking parameters), but there is no documentation on how to migrate these 2 very simple settings to the new format. The upgrade docs explain the new var expansion and a matrix with old and new parameters. But this info is completely missing for sieve. The doc only points to "script storage". Really? You couldn't have added these 2 parameters to the old-new matrix? I am not asking you to do this for every single sieve parameter, but at least for the 2 or 3 most used ones. Sorry for my rant, but I had to get it out there to not go insane. Cheers, K. C. -- regards Helmut K. C.

Did I configure this? Or is this default behaviour of dovecot? How can I turn this off if this is a standard config?
