Hello, I'm using dovecot lmtp with Postfix. I'm enabling SMTPUTF8 (EAI), but when Postfix (v 3.1.2) tries to deliver the message to dovecot-lmtp it receive this error: status=bounced (SMTPUTF8 is required, but was not offered by host dlvmx.espsrv.net[private/dovecot-lmtp] I'm not sure if Dovecot lda and lmpt support EAI and how can I enable it. I've just found and old thread: http://www.dovecot.org/list/dovecot/2013-January/087756.html Thanks for your help. -- Igor Colombi

pop3 deleted count
by Dave 16 Sep '16

16 Sep '16

On pop3 logout, we're seeing log lines where the deleted count is blank (using default pop3_logout_format), so "del=%d/%m" is displaying in the logs as: "del=/1186" for example. In src/pop3/pop3-client.c:552: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : 0; Shouldn't this be: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : "0"; (very minor bug) -- Dave

Hello, With Maildir++ it is possible to store list of IMAP message keyworkds (tags in Thunderbird) on server in dovecot-keywords file. Is it possible the same with mbox mailboxes? My mbox directory contains .subscriptions file, but no .dovecot-keywords file. -- WBR, Anton Yuzhaninov

Re: 2.2.25 dumps core with "Panic: file imap-client.c: line 837 (client_check_command_hangs): assertion failed: (client->io != NULL)"

Hello Timo, from the maintainer of the OpenCSW package I got the below answer. As the newly build package yields another different commit hash (which I cannot find on GitHub too), I would ask, if you are sure that the commit hash-output in 'doveconf -n' is generated correctly? The headline of 'doveconf -n' with the newly build package is # 2.2.25 (68082dc): /etc/opt/csw/dovecot/dovecot.conf Many thanks for your help, Andreas -------- Weitergeleitete Nachricht -------- Betreff: Re: OpenCSW question about package CSWdovecot Datum: Tue, 30 Aug 2016 08:56:44 -0700 Von: jgoerzen <jgoerzen(a)opencsw.org> An: piper(a)hrz.uni-marburg.de Hello Andreas, The OpenCSW dovecot package was built using the 2.2.25 version release tarball. No code changes or patches have been applied. I'm not sure what happened. I will respin new packages and then check to see if the git-commit hash is correct.

No Autoindex?
by Larry Rosenman 14 Sep '16

14 Sep '16

I used to get my mail auto-indexed, but something(tm) changed recently, but I'm not sure what. I do have fts_autoindex = yes in my dovecot config, and if I do a doveadm index \* it does the index.

How to obtain a "non-stripped" executable for producing a usable core-dump
by Ben Johnson 14 Sep '16

14 Sep '16

Hello, I'm attempting to capture a core-dump file, and gdb reports warning: core file may not match specified executable file. And only after installing "dovecot-dbg" on my system (Ubuntu 16.04 LTS) does gdb report further warning: the debug information found in "/lib64/ld-2.23.so" does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch). It took some searching the internet to realize that both messages are likely the result of having a "stripped" executable: # file /usr/lib/dovecot/dovecot-lda /usr/lib/dovecot/dovecot-lda: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=49c9c607c304a5c853c05a4ccb9e4b995f185ac4, stripped So, how best I am I to obtain a "non-stripped" dovecot-lda executable? Must I forego my distro's repositories and download the dovecot source, compiling every executable and all plugins "from scratch", in order to obtain a useful core-dump file? Perhaps the bug report instructions at http://www.dovecot.org/bugreport.html should mention "stripped" executables and how to avoid them. Perhaps I am simply ignorant, but if that is the case, there is little to no hope for the "average user" where submitting bug reports is concerned. Any guidance would be most appreciated. Thanks in advance, -Ben

Limit replication to one user
by Arne Hoffmann 14 Sep '16

14 Sep '16

Hello, we have a setup here where the main (and only important) feature of the IMAP server is the public folder. Two Dovecot instances are running in a active/passive cluster and mailstorage should be replicated between the two. Since there is a race condition when using public namespaces (locking on user level and not on mailbox level) I had the intention of limiting the replication to one user. I read somewhere that dsync is replicating all the users the command "doveadm user '*'" shows. And the command only shows *one* user because I have modified the iterate_query: ,----[/etc/dovecot/mysql.conf] | iterate_query = SELECT username AS user FROM mailbox WHERE username = 'data_replication(a)example.com' `---- root [~]# doveadm user '*' data_replication(a)example.com root [~]# So, why does Dovecot still replicate mails from other users inboxes? And why does doveadm replicator still show other users? root [~]# doveadm replicator status '*' username priority fast sync full sync success sync failed data_replication(a)example.com none 00:57:14 01:13:21 00:57:12 - arne.hoffmann(a)example.com none 00:20:04 00:31:40 00:20:02 - root [~]# [I removed some whitespace to keep line length in check] Any explanation of this behavior would be just awesome.

Dovecot con Autentication Checkpassword error signal 111
by zerocool＠modemsoft.it 13 Sep '16

13 Sep '16

Good morning, It is the first time I write in this mailing list and I apologize in advance for possible nonsense that i can write. I have a mail server with qmail + courier imap and I would "Migrate" to dovecot. I installed the package and configured the components necessary to me using as system autentication checkpassword. I have verified the checkpassword operation without the processor usage of Dovecot and is functioning. When you perform the tests with dovecot from the logs out these errors: auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15375 died with signal 11 auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15376 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured master: Warning: Killed with signal 15 (by pid=15479 uid=0 code=kill) or : auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15851 died with signal 11 auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15852 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=192.168.1.113, lip=192.168.1.113, secured imap-login: Info: Disconnected: Too many invalid commands (no auth attempts in 102 secs): user=<>, rip=192.168.1.235, lip=192.168.1.113 auth: Error: checkpassword(plutos,192.168.1.235,<7pLd+FI81uXAqAHr>): Child 15870 died with signal 11 It is already a long time that we slam but I can not figure out where to make the mistake.

Capturing dovecot core dump and debugging with gdb: ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.

Hello, I'm experiencing a segfault, so I've followed the steps at http://www.dovecot.org/bugreport.html in an effort to capture the information necessary to submit a bug report. Full "doveconf -n" output is at the end of this message.
