Crash in dovecot snippet when using imapc
by John van der Kamp 20 Mar '24

20 Mar '24

Hello, I've found a crash in a very specific setup. A dovecot server with imapc connection needs to receive an email with no body contents for the intent of generating a preview/snippet. It crashes somewhere deep in the jungle of istream and snapshots. I've included a script which sets up the systems to reproduce the crash. I've tested this with several versions. 2.3.16 doesn't seem to be affected, but 2.3.20 and 2.3.21 are affect. For me it produces a traceback like this, using the ubuntu version from here: https://packages.ubuntu.com/noble/dovecot-core (gdb) bt #0 __pthread_kill_implementation (no_tid=0, signo=6, threadid=140530132887360) at ./nptl/pthread_kill.c:44 #1 __pthread_kill_internal (signo=6, threadid=140530132887360) at ./nptl/pthread_kill.c:78 #2 __GI___pthread_kill (threadid=140530132887360, signo=signo@entry=6) at ./nptl/pthread_kill.c:89 #3 0x00007fcfb8842476 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #4 0x00007fcfb88287f3 in __GI_abort () at ./stdlib/abort.c:79 #5 0x00007fcfb8b37fe5 in default_fatal_finish (status=0, type=LOG_TYPE_PANIC) at ../lib/failures.c:465 #6 fatal_handler_real (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:477 #7 0x00007fcfb8be50d7 in i_internal_fatal_handler (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:879 #8 0x00007fcfb8b37eea in i_panic (format=0x7fcfb8c29020 "file %s: line %d (%s): assertion failed: (%s)") at ../lib/failures.c:530 #9 0x00007fcfb8b3387b in i_stream_header_filter_snapshot_free (_snapshot=<optimized out>) at ../lib-mail/istream-header-filter.c:663 #10 i_stream_header_filter_snapshot_free (_snapshot=0x55dabe297a60) at ../lib-mail/istream-header-filter.c:655 #11 0x00007fcfb8bf25ac in i_stream_snapshot_free (_snapshot=_snapshot@entry=0x55dabe29b0d0) at ../lib/istream.c:253 #12 0x00007fcfb8bf2654 in i_stream_unref (stream=0x7ffc16cc7fa0) at ../lib/istream.c:66 #13 0x00007fcfb8d96baa in index_mail_write_body_snippet (mail=0x55dabe292058) at index/index-mail.c:1151 #14 0x00007fcfb8d97e48 in index_mail_parse_bodystructure (mail=0x55dabe292058, field=MAIL_CACHE_BODY_SNIPPET) at index/index-mail.c:1551 #15 0x00007fcfb8d97fe2 in index_mail_fetch_body_snippet (value_r=0x7ffc16cc8050, mail=0x55dabe292058) at index/index-mail.c:1602 #16 index_mail_get_special (_mail=0x55dabe292058, field=<optimized out>, value_r=0x7ffc16cc8050) at index/index-mail.c:1730 #17 0x00007fcfb8d16ffe in mail_get_special (mail=mail@entry=0x55dabe292058, field=field@entry=MAIL_FETCH_BODY_SNIPPET, value_r=value_r@entry=0x7ffc16cc8050) at /home/ubuntu/dovecot/new/dovecot-2.3.21+dfsg1/src/lib-storage/mail.c:418 #18 0x000055dabc52645c in fetch_snippet (ctx=0x55dabe26e050, mail=0x55dabe292058, preview=0x55dabe28f1f8) at ./src/imap/imap-fetch-body.c:615 #19 0x000055dabc52b5cc in imap_fetch_more_int (ctx=0x55dabe26e050, cancel=false) at ./src/imap/imap-fetch.c:562 #20 0x000055dabc52b8ad in imap_fetch_more (ctx=0x55dabe26e050, cmd=0x55dabe26de98) at ./src/imap/imap-fetch.c:617 #21 0x000055dabc51fd07 in cmd_fetch (cmd=0x55dabe26de98) at ./src/imap/cmd-fetch.c:382 #22 0x000055dabc528af4 in command_exec (cmd=0x55dabe26de98) at ./src/imap/imap-commands.c:201 #23 0x000055dabc52e9e2 in client_command_input (cmd=<optimized out>) at ./src/imap/imap-client.c:1237 #24 0x000055dabc52ea96 in client_command_input (cmd=<optimized out>) at ./src/imap/imap-client.c:1307 #25 0x000055dabc52eeed in client_handle_next_command (remove_io_r=<synthetic pointer>, client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1349 #26 client_handle_input (client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1363 #27 0x000055dabc52f2c4 in client_input (client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1407 #28 0x00007fcfb8bfe27d in io_loop_call_io (io=0x55dabe26e660) at ../lib/ioloop.c:737 #29 0x00007fcfb8bff81a in io_loop_handler_run_internal (ioloop=0x55dabe243fd0) at ../lib/ioloop-epoll.c:222 #30 0x00007fcfb8bff8d4 in io_loop_handler_run (ioloop=0x55dabe243fd0) at ../lib/ioloop.c:789 #31 0x00007fcfb8bffa90 in io_loop_run (ioloop=0x55dabe243fd0) at ../lib/ioloop.c:762 #32 0x00007fcfb8b6ce57 in master_service_run (service=0x55dabe243e20, callback=callback@entry=0x55dabc533210 <client_connected>) at ../lib-master/master-service.c:878 #33 0x000055dabc51ad37 in main (argc=<optimized out>, argv=<optimized out>) at ./src/imap/main.c:575 John Hello, I've found a crash in a very specific setup.

JMAP status?

Just wondering how/if JMAP support is coming along. It seems to offer major protocol advantages to a connection-oriented protocol like IMAP; I’m curious to see how it performs in the real world.

Bug/Warning not sure which
by Richard Shetron 04 Mar '24

04 Mar '24

Hello, My sysadmin and I spent a couple hours trying to figure out a POP3 problem that has worked for about 20 or so years. We run our own dns for sgeinc.com. I've always used mail.sgeinc.com as my incoming and outgoing server. At various times mail has been an alias for another machine. It's currently on the same address as sge.sgeinc.com. On the update forced on us on 2/22/24 or 2/23/24 it stopped working. It still works as an outgoing server but incoming POP3 it stopped working. It started working when I changed my incoming server to sge.sgeinc.com. You might want to look into it or not. We chased the initial problem to, we think, ssh-keygen in /usr/local/bin/ which was Not found but is there. Thanks root@sge:/usr/local/bin# dovecot -n # 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.2 () # OS: Linux 5.4.0-172-generic x86_64 Ubuntu 20.04.6 LTS # Hostname: sge.sgeinc.com auth_mechanisms = plain login mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap lmtp pop3" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = postfix mode = 0660 user = postfix } } service pop3-login { inet_listener pop3 { port = 110 } } ssl = required ssl_cert = </etc/letsencrypt/live/sgeinc.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd }

better delivery mechanism to maildir?
by dovecot.org＠schildbach.de 03 Mar '24

03 Mar '24

As many of you probably are, I'm using Postfix together with Dovecot. Postfix delivers mail for my users by writing them directly to the filesystem (maildir). I wonder is there a better alternative? I'd like to separate the two services on different physical machines, so a shared filesystem isn't trivial any more. (I'd also like to stay with maildir storage and rather not do SQL or similar.) Can mail be delivered via IMAP for example? Or is there some other delivery protocol I don't know about that both Dovecot and Postfix support? Thanks!

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

Help running dovecot with sieve
by pereirar2z＠gmail.com 23 Feb '24

23 Feb '24

Hi all, I'm running dovecot-pigeonhole-2.3.21-1.x86_64 & dovecot-2.3.21-1.x86_64 + roundcube 1.6.6 on my redhat server. Mailserver is working as expected with the exception fo the Filters.
