Error: /proc/self/status is larger than expected
by Elisamuel Resto Donate 06 Apr '23

Hello, Writing to get some insight as to how I might rid myself of a the pesky error message on the subject. Every binary throws out that error, every LMTP delivery... basically every time any dovecot binary is executed. I am unsure if this is configuration related or not, but intuition says it is an issue with a kernel feature or compiler issue. I saw the error message in the source code (file ), but I don't understand enough of the dovecot architecture or what the code itself is doing in this case. Below and excerpt of a few lines of logs. Since I don't know what specifically this would relate to (and I don't quite remember the command to send the "safe" version of the configuration), I am sending this message in hopes that whatever is needed can be asked and I will provide it.

Wildcard delivery from Postfix to Dovecot LDA issues
by EML 01 Apr '23

01 Apr '23

[apologies for postfix/dovecot cross-post] How, exactly, do postfix and dovecot communicate when postfix attempts to determine whether to deliver a message to the dovecot LDA, or to bounce it? In other words, how does postfix decide to bounce foo, and deliver bar, in these log messages: postfix/pipe[11857]: 933BCA071A: to=<foo(a)example.com>, relay=dovecot, ... status=bounced (user unknown) postfix/pipe[12266]: 8AD51A071A: to=<bar(a)example.com>, relay=dovecot, ... status=sent (delivered via dovecot service) The reason I ask is that the obvious answer with the main.cf setup doesn't appear to be sufficient, and dovecot appears to check whether or not the recipient exists in the userdb passwd file before allowing delivery. I have postfix set up for virtual hosts, as follows: virtual_mailbox_domains = example.com, sub.example.com virtual_mailbox_maps = hash:/var/www1/vdomains virtual_transport = dovecot where vdomains contains: bar(a)sub.example.com example.com/test/ bar(a)example.com example.com/test/ @sub.example.com example.com/test/ @example.com example.com/test/ postfix will deliver to bar(a)example.com, but not foo(a)example.com. I can't deliver anything to the subdomain. The interesting thing is that 'bar' already has a dovecot mailbox (the 'test' mailbox), but 'foo' doesn't. If this is correct, how do I do wildcard deliveries to dovecot, particularly for the subdomain?

Dovecot error invalid service_fd
by Michel Verdier 30 Mar '23

30 Mar '23

Hi all On debian stable, dovecot 2.3.13+dfsg1-2+deb11u1 and postfix 3.5.17-0+deb11u1 I set postfix sending mails to dovecot for mailbox storage: mailbox_transport = lmtp:unix:private/dovecot-lmtp dovecot listen with lmtp: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0666 user = postfix group = postfix } } passdb { driver = pam args = session=yes cache_key=%u%r%l dovecot } userdb { driver = passwd } # ls -l /var/spool/postfix/private/dovecot-lmtp srw-rw-rw- 1 postfix postfix 0 27 mars 11:24 /var/spool/postfix/private/dovecot-lmtp I get logs like this: postfix/lmtp[271076]: 6DB551008B3C1: to=..., relay=...[private/dovecot-lmtp], delay=0.7, delays=0.29/0.04/0.11/0.26, dsn=2.0.0, status=sent (250 2.0.0 ... postfix/qmgr[197419]: 6DB551008B3C1: removed dovecot: lmtp(271077): Disconnect from local: Client has quit the connection (state=READY) dovecot: log(253615): Error: Received master input for invalid service_fd 27: 27 271079 BYE I identify 271079 as the pid for dovecot auth worker process. If I add a timeout in dovecot: service auth-worker { idle_kill = 10s } Then I see error log coming 10 seconds after the end of every lmtp connexion from postfix. There is no other log messages around even with debug enable in dovecot. And mails are correctly delivered. Am I missing something or is this to be ignored? Cheers

Dovecot submission proxy constraints
by Peter Wienemann 29 Mar '23

29 Mar '23

Dear Dovecot experts, in 2017 Stephan Bosch mentioned in an email about the Dovecot submission proxy [0]: "The current implementation does require that the proxy has direct access to the user's mailbox for BURL (e.g. by running it on the same host as imap), but that restriction should be resolved soon, allowing for more complex setups." Is the mentioned restriction (access to mailbox) still valid in 2023 or has this constraint been lifted in the meantime? Best regards, Peter [0] https://dovecot.org/pipermail/dovecot/2017-December/110282.html

How to use dovecot with more recent versions of solr (8x, 9x)?
by jkdv＠w3.org 27 Mar '23

27 Mar '23

Hello, dovecot version 2.3.13 (89f716dc2) The dovecot solr installation guide [1] gives links and configuration info for sorl 7.7.0. However, sorl was deprecated some time ago. Those links to 7.7.0 don't work anymore. Sorl is currently available in versions 8.11.2 and 9.1.1 [3]. Specifically, one section in the guide states [2]: [[ Install schema.xml and solrconfig.xml Copy doc/solr-config-7.7.0.xml and doc/solr-schema-7.7.0.xml (Since Dovecot 2.3.6+) to /var/solr/data/dovecot/conf/ as solrconfig.xml and schema.xml. The managed-schema file is generated based on schema.xml. ]] Could someone confirm me if those 7.7.0 configuration files are compatible with 8.11.2? A diff between those files and the ones from the 8.11.2 dist reveal some changes, starting from the LuceneVersion. If they are not compatible, could someone tell me what changes were done in the doc/solr files that need to be replicated in the 8.x and 9.x versions? The doc is very opaque there as it only states that you should replace those files but doesn't go into details as to why, making it confusing on how to upgrade to a new version of solr. It would be great if the dovecot/solr doc page could be upgraded to reflect the new versions of solr. Thanks in advance for your help, --jose [1] https://doc.dovecot.org/configuration_manual/fts/solr/ [2] https://doc.dovecot.org/configuration_manual/fts/solr/#solr-configuration [3] https://downloads.apache.org/lucene/solr/

doveadm expunge unnecessarily tries to access TLS key
by Jesper Dybdal 27 Mar '23

27 Mar '23

I have just upgraded my Debian Buster (Dovecot 2.3.4, I think it was) to Bullseye (Dovecot 2.3.13). The Dovecot server works fine, which of course is the really important thing. But I have a cron job that cleans up all old mail from the mailbox that I use for my mobile phone by running "doveadm expunge" every night. That worked fine in 2.3.4, but now it fails: > jdmobile@nuser:~$ doveadm expunge mailbox '*' before 25d > doveconf: Fatal: Error in configuration file > /etc/dovecot/conf.d/10-ssl.conf line 23: ssl_cert: Can't open file > /etc/letsencrypt/live/nuser.dybdal.dk/fullchain.pem: Permission denied Of course, doveadm cannot access the TLS key when running as a normal user. But why should it try to access that key at all when I have just asked it to clean up my own files in my own Maildir? Is there a way to make it not try to access that key and do its job anyway? Or another way to delete old mail? (I could give it a "-u jdmobile" option and run it as root - but I really like to run things like that as a non-privileged user, so I won't make a stupid mistake that destroys the wrong mailbox.) Thanks, Jesper -- Jesper Dybdal https://www.dybdal.dk

Dovecot LTO build failure
by Arjen de Korte 26 Mar '23

26 Mar '23

In openSUSE Tumbleweed (and several other distributions as well), packages are build by default with linktime optimization (LTO) enabled. This didn´t work for Dovecot, so until now LTO was disabled for Dovecot. There is a way to make it work though, see the following link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=997513#20 So far a fix has not made it to upstream, the latest version 2.3.30 still fails to build without this patch. Is there any news to report regarding this?

User authentication using local file
by Horst Simon 22 Mar '23

22 Mar '23

I try to configure to have user authenticate to a local file called users, with their mailboxes in ../../spool/dovecot, not in their home directories. I have this working correctly with pam authentication on different servers(openSuse and macOS). This server has no pam authentication so I need to use a local file, but I can not make any sense of the documentation, can someone please help on which files I need to change and to which values. I tried several options but getting all kind of errors with UID. Horst
