pop3-login logging double Disconencted
by Noel Butler 26 Jan '22

26 Jan '22

Hi all, Wondering if anyone else is seeing this double Disconnected in the logs with current stable version, it only happens for pop3-login, and only with Too many commands... other pop3-login logging with Disconnected like Connection closed (no auth attempts... etc are fine Example of anomaly - pop3-login: Info: Disconnected: Disconnected: Too many bad commands (no auth attempts in ... If anyone running 2.3.17.1 sees this or does not see it on Too many bad... or at all, kindly mind letting me know, not sure if something has gone haywire here or its a bug that needs reporting since logs indicate this only occurred after updating to the point 1 release. -- Regards, Noel Butler This Email, including attachments, may contain legally privileged information, therefore at all times remains confidential and subject to copyright protected under international law.

noob maildir question
by mikfum 25 Jan '22

25 Jan '22

I would like to ask if it is an acceptable practice to manage messages in the maildir as a file (move them from one folder to another) while dovecot is in stop state thinking that it will be rebuild to the next imap user login thanks for your patience:) mik

zlib.read errors after upgrade from 2.3.15 to 2.3.17.1
by Arno Schneider 24 Jan '22

24 Jan '22

After upgrading my mailserver from buster to bullseye and dovecot 2.3.15 to 2.3.17.1 I got the following errors: Jan 22 14:22:32 Warning: doveadm(user1)<2953060><49b0NRQF7GFkDy0ALVPUUA>: mdbox /local/mail/user1/storage: rebuilding indexes Jan 22 14:22:39 Error: doveadm(user2)<2953112><awsPGB8F7GGYDy0ALVPUUA>: dsync(2nd.dovecot.server): read(compress(/local/mail/user2/storage/m.4650)) failed: read(/local/mail/user2/storage/m.4650) failed: zlib.read(/local/mail/user2/storage/m.4650): unexpected EOF at 7038367 (last sent=mail, last recv=mail_request (EOL)) I have 2 dovecot servers in a multi-master configuration. The both servers are synced with dsync and the users are routed through a dovecot directors. Any hints where I can continue to investigate / solve this issue? best regards, arno

Why would dovecot not be answering
by Ruben Safir 23 Jan '22

23 Jan '22

I am really lost as to why dovecot is not authenticating I have smtpd_sasl_type = dovecot in main.cf and # Postfix smtp-auth unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } in /etc/dovecot/conf.d/10-master.conf I want it to authenticate on submition only Everything I read says this should do it, but I am up against a wall. I have no debugging information or log at all to confirm what postfix is doing. -- So many immigrant groups have swept through our town that Brooklyn, like Atlantis, reaches mythological proportions in the mind of the world - RI Safir 1998 http://www.mrbrklyn.com DRM is THEFT - We are the STAKEHOLDERS - RI Safir 2002 http://www.nylxs.com - Leadership Development in Free Software http://www2.mrbrklyn.com/resources - Unpublished Archive http://www.coinhangout.com - coins! http://www.brooklyn-living.com Being so tracked is for FARM ANIMALS and extermination camps, but incompatible with living as a free human being. -RI Safir 2013

S3 integration w Dovecot
by Martin Olsen 21 Jan '22

21 Jan '22

Good morning, day, evening :P As stated on documentation S3-compatible Storages — Dovecot documentation <https://doc.dovecot.org/configuration_manual/mail_location/obox/s3/> only AWS S3 is officially supported. However, we know that Scality has been successfully integrated at some larger corporations. Particularly curious if anyone has integrated with Pure S3 object storage solution, or any other for that matter? Just looking at some different options. - Sincerely, Martin.

sockets created for lmtp
by Mike 20 Jan '22

20 Jan '22

Was recently configuring lmtp to listen in the postfix spool for mail. I set the socket as suggested in the documentation, however, when I look at what sockets were created there was an additional one for dovecot. Since I made the change, my expectation would have been just the one that I set up. I doubt it impacts it negatively, but I wanted to understand if I configured things correctly or not. Thanks. Mike

FTS Tokenization filters normalizer-icu vs lowercase
by Alessio Cecchi 20 Jan '22

20 Jan '22

Hi, I'm trying to setup fts-flatcurve with tokenization. What are the differences/benefits with "fts_filters = normalizer-icu" vs "fts_filters = lowercase"? Reading the Doc I found about normalizer-icu "This is potentially very resource intensive." and about lowercase "Supports UTF8, when compiled with libicu". So, using lowercase is almost the same that normalizer-icu but faster? FYI for using fts-flatcurve with dovecot RPM packages from repo.dovecot.org you have to rebuild with --with-icu --with-stemmer --with-textcat and related library. Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice
