Update from 2.3.16 to 2.3.17 Received invalid SSL certificate: unable to get certificate CRL
by Salatiel Filho 08 Jan '22

08 Jan '22

Hi, after updating from dovecot.x86_64 2:2.3.16-2 to 2:2.3.17.1-1 on AlmaLinux 8 my dovecot replication stopped working. Log is full of Error: doveadm server disconnected before handshake: Received invalid SSL certificate: unable to get certificate CRL: /CN=my.domain.redacted (check ssl_client_ca_* settings?) No configuration has changed on my side. My certificate is a wildcard certificate ( not sure if related ). I am also replicating over tcps. Anyone else facing this issue? Atenciosamente/Kind regards, Salatiel

feature-request: make received-header on submission optional or at least drop the ip in it
by dc-ml＠dvl.werbittewas.de 07 Jan '22

07 Jan '22

hi. we're just trying to re-structure a system and want to use dovcots submission-ability. because the github-repository have no entry for any issues at all, we're sending this feature-fequest to this ML. unfortunately there doesn't seem to be any option to drop the received-header at all or at least hide the IP of the user. because the client-ip is covered by GDPR as personal data and so it should never shown to others without a certain reason, we want to hide it, but there's no "submission_add_received_header"-option like for lmtp and it doesn't seem to be any other option to hide this information. maybe this is possible to implement in near future? thanks a lot. best regards d.

Dovecot fixing maildir message size?
by Grant Keller 07 Jan '22

07 Jan '22

We recently updated dovecot from 2.1.17 to 2.3.10. It used to be when we encountered the following error: Jan 6 15:29:20 d.imapd.sonic.net dovecot: imap(momomo): session=aBd2O/LULMu4F6ia Error: Mailbox INBOX: UID=1: read(/var/spool/mail/07/00/momomo/cur/1510707300.12345_0.a.spam,S=1234:2,) failed: Cached message size larger than expected (1234 > 704, box=INBOX, UID=1) (read reason=) Dovecot would fix the size by renaming the file. Now this doesn't appear to be the case. Was there a change in behaviour, or is there an option I need to enable now to have dovecot auto fix this?

Doveadm auth test fails
by Ken Wright 07 Jan '22

07 Jan '22

I've been having trouble logging into my email server (postfix 3.4.13, dovecot 2.3.7.2, postfixadmin 3.3.8). I decided to try the doveadm auth test, and got the following result: kwright@grace:~$ sudo doveadm auth test me(a)mydomain.com Password: passdb: me(a)mydomain.com auth failed extra fields: user=me(a)mydomain.com I logged in to PostfixAdmin and made sure I was using the correct password, but got exactly the same result afterward. Should I have restarted Dovecot after changing the password? I'm totally confused by this problem; any and all suggestions will be gratefully received! Ken

Enable push notifications for all users
by Felix Ingram 06 Jan '22

06 Jan '22

Hello all, Is there a way to enable push notifications for all users, rather than having to enable them one by one? My thinking was to set mail_attribute_dict to a static file but I can’t work out what I would need to put in it. (I’ve now realised that that will not allow me to have other attributes to be different per user, but that’s not a real issue with my use case) If a flat file isn’t the answer, then is a SQL dict my best bet? Thanks in advance, Felix

Hi Alex, thanks for your answer, I think this could be related to Dovecot version in use, in our case it is the same: 2.3.4.1 (f79e8e7e4). It could be useful to know if someone can confirm this assumption so we can try an upgrade to the latest version hoping this could solve our issue.

Hi John, You are right this was not a dovecot solr query. It is really strange everything seems to work with Dovecot 2.3.4. E.g. search and rebuilding index from scratch using doveadm.

Can't connect to database

master: service(imap): child xxxx killed with signal 11
by Lukas Matasovsky 02 Jan '22

02 Jan '22

Dear Maintainer, I have several dovecot installations, all of them stopped working with the upgrade from .16 to .17. Maybe I am missing something, or it's a bug. All I can see is a signal 11 after each login attempt. Attached you can find a sysreport plus a core dump, both from different states of configuration (I reverted the core-dump settings later on) of the same server, but the effect has been the same ever since upgrading. I have other servers that use pam (not mariadb) and local maildirs that show the same behavior. For now, I have downgraded all servers, if needed I could run some more tests. Thank you for checking & cheers, Lukas

Dovecot Docker Image Volumes
by Thomas Bellebaum 02 Jan '22

02 Jan '22

Hello there and happy new year, I have a question/request regarding the Docker Image hosted at https://hub.docker.com/r/dovecot/dovecot. The Dockerfile itself declares two volumes: - `/etc/dovecot` for configuration data - `/srv/mail` for mail storage It seems inconvenient in some cases to have the image create these volumes, especially in case of the former. Consider a minimal Dockerfile like the following: ``` FROM dovecot/dovecot:latest COPY dovecot.conf /etc/dovecot/dovecot.conf ``` This creates a new image building on top of the official one, which has statically configured configuration, and thus does not need to save its config in a volume. Yet currently, since the base image exports volumes, a config volume is created. A user might also choose to save mail in a different directory or even in a remote SQL database, rendering the second volume unnecessary. I would like to know a bit about the reasons for declaring the volumes, and suggest removing the line, should this be an option. Some impact considerations: - Removing the volumes for future image versions will not impact existing deployments building on tags other than `latest`. - As the default (example) configuration is not very useful for non-test-setups, most people have probably assigned the config volume explicitly, e.g. using docker's `-v` option. These people will also not be affected. - The description explicitly states to mount `/srv/mail/`, but some people might rely on the the automatic volume creation nonetheless. - Some obscure proprietary scripts may rely on the current behavior. In any case, if the volumes are no longer declared, the image description should mention that the mail storage location (the default being `/var/mail`) must be saved e.g. by using volumes, and probably also that the configuration is expected at `/etc/dovecot/dovecot.conf`. Stay healthy and have a nice day, -- Thomas Bellebaum <thomas(a)bellebaum.eu>

My server has been running just fine for over a year, until I upgraded PostfixAdmin and somehow messed things up. Now I can't log in, and my mail client (Evolution, if it matters) keeps popping up an authentication request. The server is Ubuntu 20.04, my Dovecot is version 2.3.7.2, and Evolution is 3.40.4-1. I've also tried logging in with Roundcube with no success. Any insight or suggestions will be gratefully received!

I think the issue is here: ADD https://github.com/krallin/tini/releases/download/v0.19.0/tini /sbin/tini # buildkit tini has arm64 (and others) version. So it should be easy to make the container work with arm.

modernizing dovecot.conf
by Laura Steynes 30 Dec '21

30 Dec '21

Happy Holidays, And if you like me are working throughout so more senior engineers get their holidays, my condolences hah Taking the time to bring our dovecot.conf into the 2021/22 era .since its quiet time of year, Do I read it right that where we have things like service imap { process_limit = 1024 executable = imap imap-postlogin are not needed now ? and process limit is a global option? things like pop3/imap_client_workarounds = fooy are now global options, not to be in protocol { } sections ? I am reading the example conf files and see these outside the protocol sections where they have in the past lived, this is what makes me think they are now global and not needed in sub sections. but I may be missing some linking going from file to file , we have forever updated our single config file, just fixing whatever breaks when major versions break something, easier to find options in one file, rather than trying to sift through 40 included files like I am looking at now :-)

Six failed tests on openindiana (Opensolaris derivative)
by Friedrich Kink 29 Dec '21

Hi all, I'm new to this list, so please forgive me if I violate netiquette (and let me know how to improve, because it is not at all my intent). I want to create two packages (dovecot and dovecot-2.3-pigeonhole) hosted by openindiana.org. First of all, everything compiles fine and works as expected, but (there is always a but ;-)) 6 out of 41540 tests failed. To build a clean package I'd like to understand the nature of the failed tests and even more would like to fix the tests. I tried to find some hints how to tackle down the issue but was not successful so far. dovecot version 2.3.17.1, gcc version (OpenIndiana 7.5.0-il-0) 7.5.0 configure options: --sysconfdir=/etc \ --with-gssapi=plugin \ --with-ldap=plugin \ --with-sql=plugin \ --with-lua=plugin \ --with-ssl=openssl \ --with-sodium \ --with-mysql \ --with-pgsql failed tests: array_free ........................................................... : ok $(SOURCE_DIR)/src/lib/test-backtrace.c:21: Assert failed: strstr(str_c(bt), "main") != NULL backtrace_append ..................................................... : FAILED $(SOURCE_DIR)/src/lib/test-backtrace.c:45: Assert failed: strstr(bt, "main") != NULL backtrace_get ........................................................ : FAILED base32_encode() with padding ......................................... : ok buffer_replace() ..................................................... : ok $(SOURCE_DIR)/src/lib/test-buffer-istream.c:55: Assert failed: buffer_append_full_file(result, TEST_FILENAME, SIZE_MAX, &error) == BUFFER_APPEND_READ_ERROR $(SOURCE_DIR)/src/lib/test-buffer-istream.c:56: Assert failed: error != NULL && *error != '\0' buffer_append_full_file .............................................. : FAILED buffer_append_full_istream ........................................... : ok connection idle kill ................................................. : ok $(SOURCE_DIR)/src/lib/test-connection.c:563: Assert failed: !received_quit $(SOURCE_DIR)/src/lib/test-connection.c:563: Assert failed: !received_quit connection handshake failed (version) ................................ : FAILED connection handshake failed (handshake_args) ......................... : ok file_cache_switch_fd ................................................. : ok $(SOURCE_DIR)/src/lib-test/test-common.c:245: Assert failed: suppress == TRUE Error: fstat(.test_file_cache) failed: Bad file number $(SOURCE_DIR)/src/lib-test/test-common.c:245: Assert failed: suppress == TRUE Error: mmap_anon(.test_file_cache, 4096) failed: Not enough space $(SOURCE_DIR)/src/lib-test/test-common.c:245: Assert failed: suppress == TRUE Error: mremap_anon(.test_file_cache, 8192) failed: Not enough space file_cache_errors .................................................... : FAILED file_create_locked() ................................................. : ok ostream file send istream file ....................................... : ok $(SOURCE_DIR)/src/lib/test-ostream-file.c:172: Assert failed: input2->v_offset == 10 $(SOURCE_DIR)/src/lib/test-ostream-file.c:173: Assert failed: output->offset == 14 ostream file send istream sendfile() ................................. : FAILED ostream multiplex (simple) ........................................... : ok Again, compilation works clean without any warning. If you could provide some hints how to start would be great. I know I'm kind of inch picker but want to provide best experience to possible users and not give any chance to complain back to dovecot community. kind regards, Fritz
