IMAPSieve plugin and special-use attribute
by Kirill Kirilenko 02 Mar '24

02 Mar '24

Hello. Since version 0.5.9 Pigeonhole has RFC 8579 support, so Dovecot admins can easily setup redirection of spam messages into a personal mailbox identified by a particular special-use attribute rather than the mailbox's name. That's great! But, if we need to setup, for example, spam/not-spam reporting using IMAPSieve plugin, we still forced to specify mailbox's name in rules: # From elsewhere to Spam folder imapsieve_mailbox1_name = Spam imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_before = file:/etc/dovecot/report-spam.sieve # From Spam folder to elsewhere imapsieve_mailbox2_name = * imapsieve_mailbox2_from = Spam imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_before = file:/etc/dovecot/report-ham.sieve I think, it would be great to allow one to specify a special-use attribute in imapsieve_mailboxXXX_name and imapsieve_mailboxXXX_from settings. Best regards, Kirill Kirilenko.

seeking advice Error: Failed to lookup user
by noemi 28 Feb '24

28 Feb '24

Hi, I'm having some problems after activating the quota plugin: I followed the guide from the doc[0] but I'm having problems with some virtual user. I understand that,with my conf,the quota plugin check the limit of a user and then tell postfix to accept/discard the mail. i have some users under my main domain [conf in /etc/passwd] and some virtual user/domains [conf in virtusertable/virtdomains as files in postfix]. the virtual users use their local user for the login, so dovecot doesn't know they are virtual. I think the problem is here, because it is clear that the quota-status check is made by dovecot using the virtual user and not the local user[1]. understanding the problem doesn't help me in the resolution [other than burn everything and rebuild with a single management for local/virtual users using a db] but i will prefer a more soft approach. any help? my complete conf below[2] thanks, noemi [0] https://blog.sys4.de/postfix-dovecot-mailbox-quota-en.html [1] where the virtual user is mail(a)virtdomain.com and the local user is mail_virtdomain the check is done to user 'mail', thus returning a error: Nov 16 06:36:09 quota-status(other-user)<129776><OOwwMv+3VWXw+gEAKobZ8Q>: Error: Failed to lookup user mail(a)virtdomain.com: Mail access for users with UID 8 not permitted (see first_valid_uid in config file, uid from userdb lookup).

Dovecot Authentication Protocol via SSL?
by dovecot.org＠schildbach.de 24 Feb '24

24 Feb '24

I'm trying to run the Dovecot Authentication Protocol (port 12345) [1] via SSL. Here is my non-SSL config: service auth { inet_listener { port = 12345 haproxy = yes } } Adding ssl=yes to the inner block doesn't seem to change anything, I can't connect via "openssl s_client -connect", for example. I do use SSL for IMAPS, so I know my general SSL configuration is fine and I've got a valid LetsEncrypt cert. Also, Postfix doesn't appear to offer any configuration in terms of running this protocol via SSL. Question: Does it even matter? I'm about to run this protocol over untrusted networks. Is it perhaps designed to handle this situation? I'm using SASL plain authentication. I'm obviously concerned about leaking passwords, but also about leaking usernames and activity logs in general.

Add tag support to 'Lua Director'
by William Edwards 24 Feb '24

24 Feb '24

Hi, There's a thread on this mailing list from 2022 called "The end of Dovecot Director?". I lost that email, hence the new conversation. Sorry about that. TL;DR: Is anyone else needing to migrate from Director interested in adding support for 2.x-style tags to the Lua script on https://doc.dovecot.org/3.0/configuration_manual/howto/director_with_lua/? Others on this list know Lua better than I. Background: Director is being removed from 2.4 (CE) / 3.x (Pro). After some notes from the community, the following manual entry popped up: https://doc.dovecot.org/3.0/configuration_manual/howto/director_with_lua/. It provides a Lua script that serves as a kind-of replacement for Director. It expects a list of backends, and maps users to a backend at connection time. The gotcha is in the last sentence: "There are no built-in tools in Dovecot to manage the database (such as adding backends, kicking users, monitoring backends, etc.). You need to build your own tooling." So, I built a CLI tool that provides the following functionality: - CRUD backends. - CRUD user-to-backend mappings. - Health-checking backends (replacing `poolmon`). - Swapping backends (move all users on backend X to backend Y). There's one to-do, though. Director had the concept of 'tags'. This is useful when one has multiple mail clusters, and users should be routed to a specific mail cluster. The Lua script does not know this concept. If a user does not have a mapping, it simply maps the user to any backend. Which could cause users to end up on the wrong backend. Therefore, it would be useful to add tag support to the Lua script: add `user_to_tags` and `tags` tables. Add a `tag_id` column to the `backends` table. Let the Lua script create a mapping to a backend with the same `tag_id` as the user entry in `user_to_tags`. Same logic as the `director_tag` passdb field (Director on 2.x). Alternatively, drop the 'tags' term: create a `user_to_backends` table with a JSON column taking multiple backend IDs (no foreign key relations = bad consistency). Alternatively, one could ensure that the Lua script never creates a mapping itself by manually creating it before the user connects. Pretty fragile in the real world, obviously. After this final to-do, I'd be happy to open-source my CLI. With kind regards, William Edwards

User-configurable time-based mail deletion in specific folders
by Peter Reinhold 21 Feb '24

21 Feb '24

Hi I have been wondering about if Dovecot has a feature that would allow users to setup a rule for a given folder, that mails older than X days should be deleted? Or is this something that would need to be done by an external script? I have looked a bit at autoexpunge, and while the basic feature looks to be what I need, it doesn't seem to be configurable down to a specific folder on a single user. -- Peter Reinhold Hi I have been wondering about if Dovecot has a feature that would allow users to setup a rule for a given folder, that mails older than X days should be deleted?

Valid Docs for Dovecot with postgresql
by burkhardt＠konsultaner.de 19 Feb '24

19 Feb '24

Hi! The docs for dovecot with postgres are outdated and I somehow cannot connect from my dovecot instance to my postgresql database. I tried a lot but the debug output dosn't help me. What user is actually trying to connect to the postgresql? the dovecot user or root or the actual user from the connection config? I want to connect locally. Do I use password or md5 or peer with a map to connect? (tried all) simple console with pgsql command works fine. I found a couple of "How tos" but nothing helped. Are there any potential version conflict? I'm on 2.3.16 with postgresql 16. Thanks! Richi Hi!
