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.

Here is what solr sends to dovecot, the offending uid in this exmaple is '21' { "responseHeader":{ "status":0, "QTime":1, "params":{ "q":"body:Zeitserver"}}, "response":{"numFound":1,"start":0,"numFoundExact":true,"docs":[ { "uid":[21], "box":["2e60f3054059c95fbf580600eb1947e0"], "user":["oliver.krone(a)snoog.ch"], "id":"21/2e60f3054059c95fbf580600eb1947e0/oliver.krone(a)snoog.ch", "body":[" ...

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. As soon as I use version 2.3.13 things are getting wild: dovecot crashed when I re-scan the index using doveadm and search does not work anymore, after re-scan: Panic: file http-client-request.c: line 1240 (http_client_request_send_more): assertion failed: (req->payload_input != NULL) doveadm(krone(a)invectrix.ch): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7fc54cace4e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7fc54cace5fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7fc54cada49b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc4d1) [0x7fc54cada4d1] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7fc54ca31aee] -> /usr/lib/dovecot/libdovecot.so.0(+0x4aec2) [0x7fc54ca28ec2] -> /usr/lib/dovecot/libdovecot.so.0(http_client_connection_output+0xee) [0x7fc54ca7ebde] -> /usr/lib/dovecot/libdovecot.so.0(+0x122171) [0x7fc54cb00171] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7fc54caeff59] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x132) [0x7fc54caf1592] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x50) [0x7fc54caf0000] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7fc54caf01c0] -> /usr/lib/dovecot/libdovecot.so.0(+0x9c4cd) [0x7fc54ca7a4cd] -> /usr/lib/dovecot/libdovecot.so.0(http_client_request_finish_payload+0x2c) [0x7fc54ca7a6dc] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xf243) [0x7fc54c0a6243] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_parser_more+0x25) [0x7fc54c0a5345] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xbfcf) [0x7fc54c0a2fcf] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_build_mail+0xa27) [0x7fc54c0a3a87] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0x11f0b) [0x7fc54c0a8f0b] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_precache+0x2e) [0x7fc54cbf14ae] -> doveadm(+0x3761f) [0x55d18bdbf61f] -> doveadm(+0x31bad) [0x55d18bdb9bad] -> doveadm(+0x32860) [0x55d18bdba860] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x22d) [0x55d18bdbb4ad] -> doveadm(doveadm_cmd_run_ver2+0x4c8) [0x55d18bdcbb88] -> doveadm(doveadm_cmd_try_run_ver2+0x3a) [0x55d18bdcbbda] -> doveadm(main+0x1d0) [0x55d18bdaa450] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7fc54c69fd0a] -> doveadm(_start+0x2a) [0x55d18bdaa92a] and solr: 2022-01-03 00:13:20.829 ERROR (qtp1991278377-21) [ x:dovecot] o.a.s.s.HttpSolrCall null:[com.ctc.wstx.exc.WstxLazyException] com.ctc.wstx.exc.WstxIOException: Early EOF ....

Can't connect to database
by Ken Wright 02 Jan '22

02 Jan '22

Dovecot has been giving me problems for the past week or so. Today the error log showed me this: Jan 2 13:33:39 grace dovecot: auth-worker(3250): Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) - waiting for 5 seconds before retry The socket is there, showing full permissions (rwx for owner, group, and rest of the universe) so I can't understand why dovecot can't connect. Is there anyone who can help? Ken

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>

Permission denied

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! Here's the most recent entry from /var/log/mail.err: Dec 28 22:05:02 grace dovecot: lmtp(me(a)mydomain.com)<910309><SOFiMl7Qy2Hl4w0AThsuZQ>: Error: lmtp- server: conn unix:pid=906625,uid=117 [6]: rcpt me(a)mydomain.com: Mailbox INBOX: open(/var/mail/vmail/me(a)mydomain.com/tmp/1640747102.M850878P910309.grac ) failed: Permission denied Any further information available upon request!
