Nightly builds of Debian packages
by Christoph Pleger 24 Sep '18

24 Sep '18

Hello, how is the future of the automatically built nightly debian packages of dovecot? Has that project been ceased? The current auto-built version is still 2.2.28 from April 28, though 2.2.29 (with a security patch) of dovecot is out now for a while. Regards Christoph

auth_policy in a non-authenticating proxy chain
by Peter Mogensen 15 Sep '18

15 Sep '18

Hi, I was looking into the new Authentication Policy feature: https://wiki2.dovecot.org/Authentication/Policy I had kinda hoped that I would be able to enfore this in a proxy running in front of several backends. This proxy does not authenticate. It use "nopassword". But I realize that the "succes" reported in the final authpolicy req. (command=report) is not what is actaully happening on the IMAP protocol level, but rather the result of the passdb chain in the proxy. (I should probably have predicted this, it's kinda reasonable). However... since the proxy use "nopassword", ALL passdb lookups result in "success", so the proxy will never report an authentication failure to the authpolicy server. This, of course, forces me to do the authpolicy check on the backend with a shared state, but It would still have been nice to have the proxy being able to do the first "command=allow" req. and reject attemps already there even though the backend does "command=report". /Peter

Occasional crash in db-auth.c (Valgrind: Invalid read of size 4 et al.), Dovecot 2.2.27+
by Jonas Wielicki 14 Sep '18

14 Sep '18

Dear list, We are encountering troubles with dovecot using LDAP userdbs on Debian stretch (but if I’m reading valgrind correctly, we can reproduce this with vanilla dovecot master). Minimal reproducer below. While testing an upgrade to Debian stretch (dovecot-core=1:2.2.27-3+deb9u1), auth-worker has stopped working. We are using two LDAP user databases; one which is iterable, and one which is not (for reasons; I think this is not relevant; if it is, we’re happy to elaborate). The issue seems to be present in any LDAP userdb iteration handling, but it only seems to cause a crash in certain conditions which seem to be reproducibly caused by our setup for some reason. We’re seeing one of two errors. Variant A: Jan 27 13:40:05 up2 dovecot: auth-worker: Error: *** Error in `dovecot/auth': free(): corrupted unsorted chunks: 0x000056553f0fcfa0 *** Jan 27 13:40:05 up2 dovecot: auth-worker: Error: ======= Backtrace: ========= Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /lib/x86_64-linux-gnu/ libc.so.6(+0x70bcb)[0x7f78426adbcb] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /lib/x86_64-linux-gnu/ libc.so.6(+0x76f96)[0x7f78426b3f96] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /lib/x86_64-linux-gnu/ libc.so.6(+0x777de)[0x7f78426b47de] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/modules/ auth/libauthdb_ldap.so(+0x5bde)[0x7f7842008bde] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/ libdovecot.so.0(io_loop_call_io+0x52)[0x7f78430cfdd2] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/ libdovecot.so.0(io_loop_handler_run_internal+0x109)[0x7f78430d1409] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/ libdovecot.so.0(io_loop_handler_run+0x3c)[0x7f78430cfe6c] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/ libdovecot.so.0(io_loop_run+0x38)[0x7f78430d0018] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /usr/lib/dovecot/ libdovecot.so.0(master_service_run+0x13)[0x7f7843057e93] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: dovecot/auth(main+0x398) [0x56553da45f98] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: /lib/x86_64-linux-gnu/ libc.so.6(__libc_start_main+0xf1)[0x7f784265d2b1] Jan 27 13:40:05 up2 dovecot: auth-worker: Error: dovecot/auth(_start+0x2a) [0x56553da461aa] Variant B: Jan 27 13:06:56 up2 dovecot: auth-worker(27495): Panic: file db-ldap.c: line 840 (db_ldap_result_unref): assertion failed: (res->refcount > 0) Jan 27 13:06:56 up2 dovecot: auth-worker(27495): Error: Raw backtrace: /usr/ lib/dovecot/libdovecot.so.0(+0x95272) [0x7f027a4fc272] -> /usr/lib/dovecot/ libdovecot.so.0(+0x9536d) [0x7f027a4fc36d] -> /usr/lib/dovecot/libdovecot.so. 0(i_fatal+0) [0x7f027a492951] -> /usr/lib/dovecot/modules/auth/ libauthdb_ldap.so(+0x3868) [0x7f0279447868] -> /usr/lib/dovecot/modules/auth/ libauthdb_ldap.so(+0x5d7c) [0x7f0279449d7c] -> /usr/lib/dovecot/libdovecot.so. 0(io_loop_call_io+0x52) [0x7f027a510dd2] -> /usr/lib/dovecot/libdovecot.so. 0(io_loop_handler_run_internal+0x109) [0x7f027a512409] -> /usr/lib/dovecot/ libdovecot.so.0(io_loop_handler_run+0x3c) [0x7f027a510e6c] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f027a511018] -> /usr/lib/ dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f027a498e93] -> dovecot/ auth(main+0x398) [0x55b981cd2f98] -> /lib/x86_64-linux-gnu/libc.so. 6(__libc_start_main+0xf1) [0x7f0279a9e2b1] -> dovecot/auth(_start+0x2a) [0x55b981cd31aa] When running auth-worker within valgrind, we get more information (valgrind extract from mail.log attached for two versions of dovecot). We have attached mail.log contents for the respective valgrind runs. This seems to affect at least 2.2.27 onwards. We can reproduce the crash with our production data 100% of the time. The valgrind error is present even with very minimal setups (see below). Unfortunately, I haven’t been able so far to create an LDAP database which produces the crash as reliable as our production database does (which we cannot share for obvious reasons). Minimal Reproducer of Valgrind error: - Install dovecot 2.2.27 from debian stretch, or compile from master. - Install valgrind - In conf.d/10-auth.conf, disable auth-system.conf.ext - In conf.d/10-auth.conf, enable auth-ldap.conf.ext - Set contents of dovecot-ldap.conf.ext to: hosts = localhost base = dc=nodomain - In conf.d/10-master.conf, in section "service auth-worker", set executable = /usr/bin/valgrind /usr/lib/dovecot/auth -w (path may differ on your system) - Install an LDAP server with a database for dc=nodomain; this is trivial to do with debian: Simply install slapd and systemctl start slapd. - Start dovecot - Run doveadm user '*' - You should find the error in the mail.log. I hope this is somehow useful to fix our crash issue. We’ll be happy to provide more information as needed. kind regards, Jonas

Status of SMTPUTF8?
by Noah Tilton 14 Sep '18

14 Sep '18

I was wondering whether there is a roadmap for adding SMTPUTF8 support to Dovecot? My delivery pattern is Postfix -> Dovecot LMTP and it is choking on utf8 messages. I might be able to volunteer some of my time as a developer. Another thread about this seemed to go unanswered: http://dovecot.org/list/dovecot/2016-September/105474.html http://unix.stackexchange.com/questions/320091/configure-postfix-and-doveco… -Noah

[Dovecot] quota-status not working in distributed environment
by Benoit Panizzon 30 Jul '18

30 Jul '18

Hello List Quick overview of our set-up: Postfix / Dovecot (2.2.2.1) / MySQL Cluster on (at the moment) three Servers to create a HA environment where you could easily add additional servers as the demand or load grows. Circular dovecot replication is used so each server uses another one as replication partner and allowing one server to fail. Dovecot Proxy Feature being used, so we can use round-robin DNS and each server can forward the connecting user to the correct 'master' for his mailbox. So far, everything works as expected. Now we want to reject emails to 'full' mailboxes during SMTP to prevent backscatter and use the quota-status policy service from within postfix. That works fine, if the mailbox or it's replica is present on the machine where quota-status is called, but it fails if it's run on a machine where neither the mailbox or the replica is present. In our case, we get a correct SMTP 550 'Mailbox Full' Reject in two cases and a LMTP generated bounce in the later case. Also `doveadm quota get -u user(a)example.com` return the correct quota if run on the two machines which have the mailbox and it's copy locale, but return 0% used if run on the other machine. Is there a way to get quota-status to also use the proxy feature to request the quota information from the correct machine? Or is the postfix policy daemon call to the quota-status socket documented somewhere (it must be, but where?) so we could implement it from within the Milter? (we use the sendmail Milter API from postfix to filter spam and viruses, do sender/recipient rewriting, forward bounce matching, rate limmiting, login/IP statistics to block botnets abusing phished addresses and legal intercept stuff anyway) Kind regards Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

SIS: dovecot creates duplicated attachments (sometimes)
by Alexander Moisseev 20 Jul '18

20 Jul '18

SIS deduplication was broken in 2.2.16 and has been fixed with https://github.com/dovecot/core/commit/3b39022ea0513363241cf852b7d454c84158… but still sometimes (just several times in a month or so) dovecot creates duplicated attachments. As you can see in directory listings below all attachments was created at (about) the same time, but one of them has different inode number.

use instance-name for syslog?
by A. Schulze 26 Jun '18

Hello, When running multiple instances of dovecot on the same host (or running multiple docker container), it is hard to distinguish logs from different processes: the syslog entries are all prefixed with the same identifier "dovecot" It is hardcoded here: https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c… Would it make sense to use the already implemented instance-name as syslog ident? How do others solve that problem? Andreas
