Hello I have configured replication using dsync. It fails with a message Error: Couldn't create lock /home/admin/.dovecot-sync.lock: No such file or directory This directory predictably does not exist - all my users are supposed to be virtual. I can not find an option to switch this off. At the same time if I try manual replication I get segfault error Mar 30 17:17:24 localhost.localdomain dovecot[29063]: dsync-server(admin(a)asergis.com): Error: Couldn't create lock /home/admin/.dovecot-sync.lock: No such file or directory Mar 30 17:17:54 localhost.localdomain dovecot[29063]: dsync-server(admin(a)asergis.com): Error: sieve-storage: couldn't find storage root directory; sieve_dir was left unconfigured and autodetection failed Mar 30 17:17:54 localhost.localdomain dovecot[29063]: dsync-server(admin(a)asergis.com): Fatal: master: service(doveadm): child 29133 killed with signal 11 (core dumps disabled) Mar 30 17:17:54 localhost.localdomain kernel: doveadm-server[29133]: segfault at 58 ip 00007fa0608c9ca1 sp 00007fffbf349480 error 4 in lib10_doveadm_sieve_plugin.so[7fa0608c2000+b000] Mar 30 17:22:25 localhost.localdomain dovecot[29063]: dsync-server(admin(a)asergis.com): Error: Couldn't create lock /home/admin/.dovecot-sync.lock: No such file or directory Mar 30 17:27:58 localhost.localdomain kernel: doveadm[29153]: segfault at 58 ip 00007fc1e65baca1 sp 00007ffd1a78b020 error 4 in lib10_doveadm_sieve_plugin.so[7fc1e65b3000+b000] ** *My OS*: # cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION=" *My dovecot:* # dovecot --version 2.2.10 *My config*: auth_cache_size = 12 M auth_cache_ttl = 1 days auth_debug = yes auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyz.@ auth_verbose = yes base_dir = /var/run/dovecot/ default_client_limit = 1024 default_process_limit = 128 doveadm_password = mysecretpasswordsharedamongservers first_valid_uid = 1000 instance_name = powergate login_greeting = with a great power comes great responsibility mail_location = mdbox:/var/mail/%d/%n mail_plugins = replication notify mail_privileged_group = mail mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { auto = no special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Spam { auto = create special_use = \Junk } mailbox Trash { auto = no special_use = \Trash } mailbox virtual/All { auto = no special_use = \All } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_replica = tcp:192.168.100.11:54321 } protocols = imap lmtp service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = $default_internal_user } unix_listener replication-notify { mode = 0666 user = $default_internal_user } } service auth { client_limit = 512 inet_listener auth-client { port = 12345 } unix_listener auth-userdb { mode = 0666 } } service doveadm { inet_listener { port = 54321 } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 2 service_count = 1 } service imap { service_count = 1 } service lmtp { unix_listener lmtp { group = postfix mode = 0600 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_dh_parameters_length = 2048 ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql }

Issue with a bug with imap-login
by Grant Keller 31 Mar '18

31 Mar '18

Hello, Currently working on migrating our existing directors from 2.1.13 to 2.2.10. In 2.2.10 when issuing the logout command on an unauthenticated connection, the connection is closed before the server sends the BYE line to the client. The new version works as expected with a non-secure connection. I will include the strace output from the imap-login process that shows the connection closing before the message can be sent. # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux

debian lintian warn: hardening-no-fortify-functions
by A. Schulze 30 Mar '18

30 Mar '18

Hello, to build + packages dovecot I use the usual Debian tool chain. That includes build with selected GCC options and running lintian. I notice since a long time (read: many earlier versions, up to 2.2.35) this lintian warnings: I: dovecot-core: hardening-no-fortify-functions usr/lib/dovecot/auth N: N: This package provides an ELF binary that lacks the use of fortified libc N: functions. Either there are no potentially unfortified functions called N: by any routines, all unfortified calls have already been fully validated N: at compile-time, or the package was not built with the default Debian N: compiler flags defined by dpkg-buildflags. If built using N: dpkg-buildflags directly, be sure to import CPPFLAGS. N: N: NB: Due to false-positives, Lintian ignores some unprotected functions N: (e.g. memcpy).

Frequentl failures to create /tmp/dovecot.imap
by Peter 29 Mar '18

29 Mar '18

I am using dovecot 2.2.27 with plesk 12 and I have made no modifications to the dovecot config. my log file frequently (but not always!) reports errors that /tmp/dovecot.imap could not be created. The errors don't appear for every imap connect but for about 5% to 10% of the time. I already attempted to solve the problem by adding the following line to /etc/dovecot/dovecot.conf but that did not remove the error: mail_temp_dir = /tmp So why does dovecot mostly work without errors but sometimes fails to create the /tmp/dovecot.imap? ..excerpt from /var/log/syslog... dovecot: service=imap, user=user1(a)mydomain1.com, ip=[::1].

Release 2.3.1
by aki.tuomi＠dovecot.fi 29 Mar '18

29 Mar '18

Hi! We are releasing v2.3.1, which mostly consists of bug fixes for 2.3.0, and few improvements. This is also available via https://repo.dovecot.org if you want packages. libsodium support didn't get into this build, due to build environment issues, but 2.3.2 will contain it. * Submission server support improvements and bug fixes - Lots of bug fixes to submission server * API CHANGE: array_idx_modifiable will no longer allocate space - Particularly affects how you should check MODULE_CONTEXT result, or use REQUIRE_MODULE_CONTEXT. + mail_attachment_detection_options setting controls when $HasAttachment and $HasNoAttachment keywords are set for mails. + imap: Support fetching body snippets using FETCH (SNIPPET) or (SNIPPET (LAZY=FUZZY)) + fs-compress: Automatically detect whether input is compressed or not. Prefix the compression algorithm with "maybe-" to enable the detection, for example: "compress:maybe-gz:6:..." + Added settings to change dovecot.index* files' optimization behavior. See https://wiki2.dovecot.org/IndexFiles#Settings + Auth cache can now utilize auth workers to do password hash verification by setting auth_cache_verify_password_with_worker=yes. + Added charset_alias plugin. See https://wiki2.dovecot.org/Plugins/CharsetAlias + imap_logout_format and pop3_logout_format settings now support all of the generic variables (e.g. %{rip}, %{session}, etc.) -- Aki Tuomi Dovecot oy

Hi, The dovecot 2.3.0.1 Debian package currently fails to build on all big-endian architectures[1], due to murmurhash3 tests failing.

Master Users, ACL and POP3
by Riccardo Bicelli 28 Mar '18

28 Mar '18

Hello, I'm on Dovecot 2.0.9 and I'mfacing issues connecting via POP3 with master user. I'm using the ACL plugin, so I set up a postlogin script that sets the current user as master user: #!/bin/sh MASTER_USER=$USER exec "$@" When I login via IMAP everything seems ok, but when I try via POP3 I get: -ERR [IN-USE] Couldn't open INBOX: Mailbox doesn't exist: INBOX Connection closed by foreign host. Any hints? Thanks

Dovecot quota
by David Mehler 28 Mar '18

28 Mar '18

Hello, I'm running Dovecot on a FreeBSD system with Postfix in a virtual user setup, with Mysql. I am trying to understand the quota configuration. I've got a Mysql database with an accounts table with a quota field. I've also got two other tables one quota (currently has nothing in it an empty set), and quota2 messages and bytes which has one entry. My goal is to have different quotas for each user so say one user has a 512MB quota I put 512 in the accounts quota column, while another user might have 256MB, put 256 in the accounts quota column. These are just examples. I'm assuming messages in the quota2 table track how many messages are under that user's is it inbox or all folders in the account? And bytes is that the space being taken up again by inbox or by all messages in the account? I'm also trying to have a separate quota for my public folders, which is not working. If anyone could take a look at this configuration see if it looks good and maybe where public is not happening i'd appreciate it. Thanks. Dave.

Released Pigeonhole v0.5.1 for Dovecot v2.3.1.
by Stephan Bosch 28 Mar '18

28 Mar '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.1. You will need this release for Dovecot v2.3.1, because the previous v0.5.0.1 release will not work. Apart from compatibility changes, it only contains bugfixes. Changelog v0.5.1: - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve script. - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not assert crash or log an error for messages that disappear concurrently while applying Sieve scripts. This event is now logged as a debug message. - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

dovecot logging
by A. Schulze 27 Mar '18

27 Mar '18

Hello, I'm currently playing with a number of dovecot instances to evaluate my "next generation setup" For now I run 6 instances of dovecot, one per docker container: - 2x redirector - 2x backend #1 - 2x backend #2 All docker container use syslog. And there the problems starts. Every instance identify itself as "dovecot" That's not helpful :-/ I tried to set an instance name but that change nothing. My options are now - let rsyslogd separate the sources by IP - use logfiles files Are there other? Currently the code use a fixed string "dovecot": https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c… I would ask if it's possible to use the instance name as syslog identifier, too?

Slow imap connection to local dovecot server
by Lothar Paltins 27 Mar '18

27 Mar '18

Hi, this is my setup: OpenSuse tumbleweed dovecot 2.3.0.1 (ffd8a29) thunderbird 52.6.0 I'm running a local dovecot server on my private network to be able to access my saved mails from several computers on the network. The network is behind a firewall, therefore I'm only using plain imap on port 143 with plain text password authentification. But very often the login from thunderbird to the dovecot server takes a very long time, even if thunderbird and dovecot are running on the same machine. It can take more than a minute until I can read a message. I dont't have this problem with the remote imap servers of my mail providers. Does anybody know, why this happens or how I could debug this issue?

Duplicate mails on pop3 expunge with dsync replication on 2.2.35 (2.2.33.2 works)
by Gerald Galster 27 Mar '18

27 Mar '18

Hello, consider the following setup with dovecot 2.2.35: smtp/587 (subject: test 1535) | | mx2a.example.com --> dsync/ssh --> mx2b.example.com | pop3 fetch/expunge (uid 23) | !! dsync (copy from INBOX -> uid 24) /| dsync (expunge uid 23) / The pop3 client deletes mail from the server which triggers a copy from INBOX before it is expunged. On the next pop3 fetch you get the copy of the mail you thought had been expunged. This occurs only if mail is received by smtp on mx2a, synced to mx2b via dsync/ssh and then expunged via pop3 on mx2b. It does not occur if mail is received and expunged on mx2b. As a temporary workaround the system has been downgraded to 2.2.33.2. There are no duplicate emails after expunge with this version. 2.2.34 has not been tested. Does anyone know if there were changes in the dsync code from 2.2.33.2 to 2.2.35? Log: (mail received on mx2a.example.com and delivered via dsync to mx2b.example.com, then expunged via pop3 on mx2b.example.com -> copy/duplicate) Mar 26 15:35:57 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3922, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: copy from INBOX: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 (mail received on mx2b.example.com and expunged via pop3 on mx2b.example.com -> no copy/duplicate) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3927, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:36:10 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Thanks for looking into this Gerald

Quota set-up problems
by Marcin Norek 26 Mar '18

26 Mar '18

Hi, I've recently started using Dovecot as our main mail storage, and it's performing great. But I have a question/problems with quotas. First of we are using: dovecot --version 2.2.32 (dfbe293d4) Dovecot is a part of a pre set environment (mailcow-dockerized) Aside the inbox namespace we have set-up an additional archive ns (Archiwum) like this namespace Archiwum { type = private separator = / prefix = Archiwum/ location = maildir:/var/vmail/arch/%n:INDEXPVT=~/Maildir/Archiwum subscriptions = yes list = yes mailbox "Wyslane" { auto = subscribe } } It is on an separate disk array, and works well. The problem is that this namespace and all its sub mailboxes should have different quota then the main storage so the config is like this quota = dict:Userquota::proxy::sqlquota quota2 = maildir:ns=Archiwum quota_rule = Trash:storage=+100% quota2_rule = *:ignore It works.. but not as intender. While mail located directly in the name space are ignored everything in sub mailbox of the Archiwum is still accounted to the main quota. I've been fighting this for some time now and can not find the solution. So help would be appreciated. Regards Marcin

I tried setting the "destuser" setting on the LMTP director as follows, to preserve the original envelope rcpt: protocol lmtp { auth_socket_path = director-userdb passdb { driver = ... override_fields = destuser=%{orig_user} } } The passdb driver would return the appropriate "user" for each alias. Suppose, for example, user1 has emails user1(a)domain.tld, but also alias1(a)domain.tld. Now, it turns out that setting the destuser *changes* the backend. It seems that when the passdb returns "destuser", that username is completely ignored and the hashing of the destuser determines the backend chosen. This is incorrect, the backend should be chosen based on the returned "user", and the "destuser" should only be used for the remote login (or rcpt, in case of LMTP). I'm using version 2.2.35. The problem seems to be in lmtp/commands.c, in client_proxy_rcpt_parse_fields, line 281-285 says: } else if (strcmp(key, "user") == 0 || strcmp(key, "destuser") == 0) { /* changing the username */ *address = value; } ... So it looks as if "user" and "destuser" are treated equally in the LMTP proxy. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

Config problem: Service #0 is missing name
by Chris Ross 25 Mar '18

25 Mar '18

Okay. So following up on the problems I was discussing weeks ago, I have hand-patched dovecot to work around problems that I believe may be in libc and not dovecot. Trying to get the properly built and installed dovecot-2.2.35, however, is giving me an error I haven’t seen before. I presume that something got munged while I was hand-configuring and installing/uninstalling/reinstalling the port in recent weeks. Running on a FreeBSD 11-stable machine, when I run “service dovecot start”, it tells me: % sudo service dovecot start Starting dovecot. Fatal: Error reading configuration: Invalid settings: Service #0 is missing name /usr/local/etc/rc.d/dovecot: WARNING: failed to start dovecot % Surprisingly, googling for “Service #0 is missing name” didn’t yield a suggestion. My config is the same as it had been previously, I believe. Does anyone have an idea what might be wrong here? Thanks. - Chris

recipient delimiter and sieve filters
by André Rodier 24 Mar '18

24 Mar '18

Dear all, I have found a way to automatically copy sent emails in the "Sent" folder, but I am not sure it is the simplest and more reliable way on the long term. I am open to suggestions if I miss a feature in Dovecot - or Postfix, that allows me to do this. I vaguely remember an SMTP extension that do that, but my memory could be wrong. First, I use "~" as a recipient delimiter. Then, I set up a postfix senders_bcc_map that add the ~Sent part: andre(a)homebox.space → bcc: andre~Sent(a)homebox.space It worked, except that the emails was marked as new. I tried first to add a global sieve filter like this: ---------------------------------------------------------------------- # Sieve script executed before for user require ["fileinto","imap4flags"]; # Move automatically copied emails to the sent folder # And mark them as read if header :contains "Delivered-To" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- But it did not work, so maybe there is a trick I am not aware of. If I use the "Received" header and a regex, it works ---------------------------------------------------------------------- require ["fileinto","imap4flags","regex"]; if header :regex "Received" "for <[a-z]+~Sent(a)homebox.space>;" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- This is working perfectly, but there is limitations, IMHO. - If the recipient delimiter is not compatible with a regex (e.g. "+"), then the script will probably fail. - Parsing every new email using a regular expression might not be the best option in term of system load. So, I finally use this: ---------------------------------------------------------------------- # Move automatically copied emails to the sent folder # And mark them as read require ["fileinto","imap4flags"]; if header :contains "Received" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- My question is why the first one does not work? Does the email has been moved to the Sent folder, and dovecot sieve plugin is not able to find the email any more? Kind regards, André -- https://github.com/progmaticltd/homebox

lmtp service timeouting even after receiving full message

Isn't .\n always enough for dovecot to signal end of message? Because exim wrote full message to dovecot lmtp unix socket. Now the interesting this - exim does only one write() with 6585 bytes to write that message to lmtp. If exim needs more than one write() to do that (message is larger by some buffer) then it succeeds, dovecot accepts it. Could dovecot lmtp handling for single write() case be broken? dovecot 2.2.35 -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Dovecot replication does not replicate subscription in shared mailboxes
by Ralf Becker 23 Mar '18

23 Mar '18

We use a pair of replicating Dovecot servers. If a user subscribes to a folder, shared by an other user, in one replica, that does not get replicated to the other node. Subscription of regular folders below INBOX seem to replicate correctly. Is that a general bug, a known problem or do we need to enable that somehow. Here's our configuration for the concerned namespace: namespace users { location = mdbox:%%h/mdbox:INDEXPVT=~/shared/%%u prefix = user/%%n/ separator = / subscriptions = no type = shared } I attached the full doveconf -n.

How to stop sieve processing to skip sieve_after scripts ?
by Mr Nicolas Belan 23 Mar '18

23 Mar '18

Hello the list, I am trying to achieve filter processing using sieve, but i am not sure I can do what I want. I want to let the user decide to use my filtering script (sieve_after) or not.According to the documentation, i am trying to stop processing in user sieve script, but processing continue. I am using dovecot 2.2 (CentOS). My sieve configuration is:plugin { sieve = /var/vmail/%d/%n/%n.sieve sieve_before = /etc/dovecot/sieve/global-before sieve_after = /etc/dovecot/sieve/global [...]} 'sieve' is the filter script created by users. When trying to stop processing, it is generated by roundcube like:# rule:[deliver to mailbox] if anyof (true) { stop; } 'sieve_after' is the filter which handles the spam processing (fileinto Junk). But the processing continue until all sieve filters are processed: Mar 22 14:50:23 lda(user(a)example.com): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt=Mar 22 14:50:23 lda(user(a)example.com): Debug: Destination address: user(a)example.com (source: -a parameter) Mar 22 14:50:23 lda(user(a)example.com): Debug: sieve: Pigeonhole version 0.4.2 initializing Mar 22 14:50:23 lda(user(a)example.com): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.

limit pop login per user and per minute
by Markus Eckerl 22 Mar '18

22 Mar '18

Hi, like I have written in the subject line I want to limit the pop login per user and per minute. Currently I am having several customers which are fetching their email with popcon (MS Exchange). This has never been a problem. But... They all have got the same "technician" which take care of their systems. The problem is, that he misconfigured the servers of these customers. In detail: their servers are trying to fetch email every 2 - 5 seconds. For every email address. In the past I contacted the technician and told him about his mistake. He was not very helpful and simply told me that he is doing the same configuration since several years at all of his customer servers. Without problems. It is up to me to fix my problem myself. Well, I googled a lot but all I found is to limit for a specific IP or for a secific account. Both is not what I am looking for. Maybe someone can give me a hint?

dovecot-uidlist is not up-to-date
by Dmitry Filonov 22 Mar '18

22 Mar '18

Hi, Am using dovecot-2.2.10-8 on Centos-7 and everything seemed to be totally fine for many years. Now am trying to migrate our on-premises mail server to the cloud and I had to get some statistics. I was doing that using the doveadm utility. Unfortunately I found that the numbers don't match if I check the real messages in my Maildirs. For some account doveadm was reporting number of messages but that account didn't have any messages stored at all. So I looked a bit further and found that doveadm utility reports data form indexes and indexes are built using dovecot-uidlist data. For quite some folders these files have way more data than actual mailbox has. For example, my personal Inbox has 569 messages but dovecot-uidlist has 716 entries. I don't know when and how that happened but this happens a lot on many different mailboxes on my server. I never touched dovecot-uidlist files outside of dovecot. I might have removed messages from Maildirs though, but not at this scale. Now the question is if there's any way to tell dovecot to rebuild dovecot-uidlist files using actual Maildir data. I don't want to remove dovecot-uidlist files as this triggers the whole mailbox being re-downloaded by the imap client. With some accounts having over 100Gb of mail this is too much of a hassle. I just need dovecot itself to fix it's data. Thanks, Fil -- Dmitry Filonov Network Analyst 300 Longwood Ave. Enders-1262.2 Boston, MA 02115 617-919-4702

"failed to map segment from shared object" in sieve pipe
by Dorian Taylor 22 Mar '18

22 Mar '18

Hello, I have encountered a problem attempting to run a program in a sieve pipe. The program is a Perl script that loads a number of binary (XS) modules at runtime. The program crashes, it appears, if it tries to load too many. The (non-Perl part of the) error message is "failed to map segment from shared object” — no additional information. Cryptic error messages like this have the odour of imposed resource restrictions, so I’m wondering if there are any on the pipe/filter/execute implementation (e.g. via program_client_run). Any configuration knobs I can twiddle? Any insights for debugging? PS this is the dovecot 2.2.22 (fe789d2), the one that ships with Ubuntu Xenial. Regards, -- Dorian Taylor Make things.

Hello guys, Should the following configuration: mail_cache_fields = flags,imap.body,imap.bodystructure mail_always_cache_fields = imap.body,imap.bodystructure have an effect on the following command? doveadm index -u bob INBOX It seems to have no effect for some reason. Regards, Siva

Compiling from sources and security contexts (dovecot_selinux)
by TraxOnDaRocks 20 Mar '18

20 Mar '18

Hi, installation by prebuilt binaries creates security contexts on each file (as shown here https://linux.die.net/man/8/dovecot_selinux) so that dovecot integrates perfectly in SELinux. I've compiled instead from sources (as described here https://wiki2.dovecot.org/CompilingSource) and i'd like to know how create same security contexts of prebuilt binaries to have an identical behaviour in SELinux. Thank you

Permissions on /var/log/dovecot
by ＠lbutlr 20 Mar '18

20 Mar '18

/var/log/dovecot exists and has a lot of logging in it, but I get errors (in mail.log) on an always_bcc action in postfix: mail postfix/pipe[13015]: 401cvS0R8BzbSkL: to=<backup+073.kremels-kreme(a)doamin.tld>, relay=dovecot, delay=398058, delays=398045/13/0/0.04, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot: Permission denied ) What should the permissions on /var/log/dovecot be? (they are 640 root:wheel on FreeBSD, identical to mail.log)

Fwd: Everything works except sending mail
by Armin Tangelder 20 Mar '18

20 Mar '18

Hi people, Version of my beloved Dovecot installation: 2.2.27 (c0f36b0) I moved from a OS X server to a Linux (Ubuntu) Headless server. All fun and good to play around with. Love almost everything. In the combination with Postfix and Dovecot I’m stuck to despair into oblivion. Everything works except I cannot send mail from my (OS X) Outlook client I keep getting: Connection to the server failed or was dropped. Error Code -3253 Nothing More and nothing less. O do not get any other error in a logfile or anything. And I followed almost every installation manual I found. Postfix I can send and receive through telnet. But I just can’t get this to work… The mail doesn’t even reach Postfix queue as I cannot connect to send. I do have a awesome connection receiving my mail though ☺ Anyway: dovecot -n gives this (and I probably don’t see it anymore as I’ve been at this for several days now) # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.13.0-37-generic x86_64 Ubuntu 17.10 auth_mechanisms = plain login auth_realms = formule1.demon.nl login_greeting = Dovecot ready. mail_location = maildir:~/Maildir mail_max_userip_connections = 50 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/certs/server.crt ssl_key = # hidden, use -P to show it userdb { driver = passwd } Anything useful I would love to see. Any information needed. THNKS… Armin -- Very funny Scotty, now beam down my clothes…

Accentuated email addresses stored in LDAP
by André Rodier 20 Mar '18

20 Mar '18

Hello everyone, I have successfully set up Dovecot with an LDAP backend, and everything works like a charm, except one small use case. I know it is possible, so if anyone knows a solution, thank you! Basically, I just want to send an email to one of my email address, which contains an accent, i.e. andré(a)homebox.space.... Every other alias works, but not those with accents. They are correctly stored in the LDAP database, using base64. I suspect I would need to use base64 again before the lookup, but I don't know how to do and if it is even possible. My filter is set up as this: filter=(&(objectClass=posixAccount)(|(uid=%n)(mail=%u)(mailLocalAddress=%u))) It works perfectly for any email without accent. Thanks for your help. > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: LDAP initialization took 7 msecs > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: auth client connected (pid=0) > Mar 18 22:14:28 homebox dovecot[24636]: quota-status(andré(a)homebox.space): Debug: Loading modules from directory: /usr/lib/dovecot/modules Mar 18 22:14:28 homebox dovecot[24636]: quota-status(andré(a)homebox.space): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: master in: USER 1 andré(a)homebox.space service=quota-status > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: ldap(andré(a)homebox.space): user search: base=dc=homebox,dc=space scope=subtree filter=(&(objectClass=posixAccount)(|(uid=andré)(mailLocalAddress=andré(a)homebox.space))) fields=homeDirectory,uidNumber,gidNumber,mail > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: ldap(andré(a)homebox.space): no fields returned by the server > Mar 18 22:14:28 homebox dovecot[24636]: auth: ldap(andré(a)homebox.space): unknown user > Mar 18 22:14:28 homebox dovecot[24636]: auth: Debug: userdb out: NOTFOUND 1 > Mar 18 22:14:28 homebox dovecot[24636]: quota-status(andré(a)homebox.space): Debug: auth USER input: > Mar 18 22:14:28 homebox postfix/smtpd[24734]: NOQUEUE: reject: RCPT from smtpfr.rodier.me[164.132.53.161]: 554 5.7.1 <andré(a)homebox.space>: Recipient address rejected: Unknown user; from=<root(a)smtpuk.rodier.me> to=<andré(a)homebox.space> pro > to=ESMTP helo=<smtpuk.rodier.me> > Mar 18 22:14:28 homebox postfix/smtpd[24734]: disconnect from smtpfr.rodier.me[164.132.53.161] ehlo=1 mail=1 rcpt=0/1 data=0/1 rset=1 quit=1 commands=4/6

Strange "IMAP connection broken (server response)" errors
by Jozsef Kadlecsik 20 Mar '18

20 Mar '18

Hello, We upgraded one of our dovecot servers to debian stretch with dovecot 2.2.27 and since then one of our users has been experiencing random IMAP failures. We enabled raw logging at the server side and it shows normal IMAP commands/responses: 1507292522.222427 * 6 FETCH (FLAGS () BODYSTRUCTURE ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 4645 112 NIL NIL NIL NIL)) 1507292522.222653 00000011 OK Fetch completed (0.006 + 0.000 secs). On the client side the user runs alpine and the corresponding debug lines: IMAP DEBUG 14:22:02.216167: 00000011 FETCH 6 (BODYSTRUCTURE FLAGS) 14:22:02.217396 IMAP 14:22:02 10/6 mm_notify bye: {[127.0.0.1]:1555/imap/user="ha4aa"}INBOX: [CLOSED] IMAP connection broken (server response) 14:22:02.217471 IMAP 14:22:02 10/6 mm_log error: [CLOSED] IMAP connection broken (server response) The "[127.0.0.1]:1555/imap/user="ha4aa" part in the log comes from an socat inserted between the client and the server to check independetly the imap session.

Released Pigeonhole v0.4.23 for Dovecot v2.2.35.
by Stephan Bosch 20 Mar '18

20 Mar '18

Hello Dovecot users, Here is a new Pigeonhole release that goes with the new Dovecot v2.2.35 release. This release is not strictly necessary, as previous versions should be usable as well. This release only contains bug fixes. However, considering the rather nasty editheader bug that emerged in the previous release, upgrade is recommended. Changelog v0.4.23: - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not log an error for messages that disappear concurrently while applying Sieve scripts. This is a further improvement on the imapsieve fix in the previous release (which fixed a panic). This event is now logged as a debug message. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.23.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.23.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Controlling dovecot caching decisions
by Sivathmican Sivakumaran 19 Mar '18

19 Mar '18

Hello, It looks like the "mail_always_cache_fields" and "mail_never_cache_fields" can be used to control dovecot's caching decisions. I cannot seem to find any documentation regarding how these fields should be used. What are acceptable values for these fields? I am quite new to this so any help would be much appreciated. Regards, Siva

Replication Slave is not auto-creating domain/user folders
by Thore Bödecker 19 Mar '18

19 Mar '18

Hey all, I'm experiencing a weird and annoying issue with my 2-node dovecot replication setup. The setup is based on virtual users in a pgsql database, which is replicated from the master to a slave node. For the mails I rely on the dovecot builtin replication which has been working great for me thus far. However I noticed something was off when looking through my journal yesterday: dovecot[823]: doveadm: Error: Couldn't lock /var/vmail/foxxx0.de/qwer/.dovecot-sync.lock: safe_mkstemp(/var/vmail/foxxx0.de/qwer/.dovecot-sync.lock) failed: No such file or directory In this case the domain directory /var/vmail/foxxx0.de was already existing on the slave, but dovecot didn't bother to create the user folder before trying to lock it. The same happens when the entire domain folder is missing: dovecot[823]: doveadm: Error: Couldn't lock /var/vmail/dj-orakel.de/booking/.dovecot-sync.lock: safe_mkstemp(/var/vmail/dj-orakel.de/booking/.dovecot-sync.lock) failed: No such file or directory (in this case /var/vmail/dj-orakel.de is not existing yet) A natural first though would be "permission problem" - which I suspected too but the filesystem permissions are identical on the master and the slave: master (mx1): ---- root@valhalla ~ > stat /var/vmail/ File: /var/vmail/ Size: 4096 Blocks: 8 IO Block: 4096 directory Device: fd06h/64774d Inode: 2 Links: 28 Access: (2770/drwxrws---) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-09-04 13:04:33.837609018 +0200 Modify: 2018-03-17 18:22:47.506323895 +0100 Change: 2018-03-17 18:22:47.506323895 +0100 Birth: - root@valhalla ~ > id dovecot uid=76(dovecot) gid=76(dovecot) groups=76(dovecot) root@valhalla ~ > id vmail uid=5000(vmail) gid=5000(vmail) groups=5000(vmail) ---- replication slave (mx2): ---- root@midgard ~ > stat /var/vmail File: /var/vmail Size: 4096 Blocks: 8 IO Block: 4096 directory Device: fe02h/65026d Inode: 2 Links: 27 Access: (2770/drwxrws---) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2017-10-15 12:09:56.174209161 +0200 Modify: 2018-03-06 15:43:41.463359651 +0100 Change: 2018-03-06 15:43:41.463359651 +0100 Birth: - root@midgard ~ > id dovecot uid=76(dovecot) gid=76(dovecot) groups=76(dovecot) root@midgard ~ > id vmail uid=5000(vmail) gid=5000(vmail) groups=5000(vmail) ---- The replication service is configured in dovecot to run as user vmail, so it should not be a permission problem because the master is automatically creating the domain and user folders inside /var/vmail when new mails arrive. I highly suspect that this is some kind of regression because I can't remember having to manually create the domain/user folders on the slave before it would replicate mails for these, and there are quite a number of domains/users being replicated already.

Is possible to override Dovecot variables or Sieve env vars and extdata lookups
by MRob 19 Mar '18

19 Mar '18

Are the dovecot environment variables mutable? I'd like to override like: set "${env.vnd.dovecot.username}" "someuser(a)example.org" Or better, I prefer to override %u Dovecot variable during the userdb lookup. Is either possible? PS, when Sieve does extdata lookups for username key, where does username come from? %u? Does an override as above change the dict lookup key for extdata?

per-user virtual mailboxes

Disable SIS
by Nick Rosier 15 Mar '18

15 Mar '18

Hi, I'm currently running a small home-server with Dovecot. A long time ago I configured it with SIS enabled. I would like to stop using SIS. If I remove sis from mail_attachment_fs will the old mails that are stored in SIS-storage still be accessible? How can I convert all mailboxes to stop using SIS and store attachments back in the mails? Rgds, N.

Argon2i support in CE packages
by Grégory Oestreicher 14 Mar '18

14 Mar '18

Hi All, I've been experimenting with the Argon2i password scheme in a local setup, backed by a LDAP server, and Dovecot 2.3.0.1 can't authenticate my users for now. On the LDAP side the user passwords start with {ARGON2I} (and I can authenticate fine to the LDAP server), but it seems that the CE packages are compiled without libsodium. Is that correct? Is at this time the only alternative to recompile Dovecot myself, or are there plans to compile CE packages with libsodium? Cheers, Grégory

Assertion during dsync receive
by Ian Bobbitt 13 Mar '18

13 Mar '18

Hi, I'm getting an assertion failed on the receiving side, causing syncs to fail for one user. The servers are setup so that only one is receiving any traffic other than replication at any time. The one that's only receiving replications is the one that's failing. I've tried deleting the user's home on the receiving server, but it still crashes during the sync. Oddly, the user's home is 7.4G on the sending server, but ends up at 42G on the receiving side, even after deleting and trying a fresh sync. The mailbox implicated in the backtrace ("Spam") does have a very large number of messages in it.

Extra intermediate certificate when using ssl_alt_cert
by Peter Linss 13 Mar '18

13 Mar '18

I just added an ECDSA certificate to my mail server using ssl_alt_cert (the RSA certificate is specified by ssl_cert), both certificate files contain the certificate and a single intermediate (which currently happens to be the same intermediate from Let’s Encrypt). When connecting to the server using either RSA or ECDSA ciphers, the server sends the proper certificate, but also sends two intermediates. Apparently it’s reading the intermediate from both files and using both for all situations, rather than using only the intermediate in the RSA file for RSA certificates, and the intermediate in the ECDSA file for ECDSA certificates. I expect this will be a bigger problem when Let’s Encrypt starts using ECDSA intermediates. Removing the intermediate from the ssl_alt_cert file solves the problem (but then doesn’t allow an ECDSA intermediate to be specified).

2.2.34 broken if ssl_protocols contains !SSLv2
by Stuart Henderson 11 Mar '18

11 Mar '18

The code in ssl_protocols_to_min_protocol() to convert ssl_protocols to min/max values can't cope with strings containing "!SSLv2". dovecot: imap-login: Fatal: Unknown ssl_protocols setting: Unrecognized protocol 'SSLv2' This string might be configured explicitly by the user, or if the user hasn't configured this themselves it could also come from the default because master_service_ssl_default_settings sets this: #ifdef SSL_TXT_SSLV2 .ssl_protocols = "!SSLv2 !SSLv3", #else .ssl_protocols = "!SSLv3", #endif

Hello, I've got dovecot authenticating to a MySQL database. I've got a field varchar(128) called password. Whenever I create a password I use doveadm pw as in: doveadm pw -s sha512-crypt now i'd like to get MySQL to make a dovecot-specific password. My goal is to eventually have roundcube's password plugin working with this MySQL database to change the password. Thanks. Dave.

mail_attachment_detection_options not working
by Alessio Cecchi 09 Mar '18

09 Mar '18

Hi, I enabled mail_attachment_detection_options on dovecot 2.2.34, in 10-mail.conf I have: mail_attachment_detection_options = add-flags-on-save but when an email is delivered in mailbox (Maildir) via LMTP no flag (HasNoAttachment or HasAttachment) was added. In dovecot-keywords file I have: 0 $HasNoAttachment 1 NonJunk 2 $HasAttachment so I thinks that the feature was eanbled but is unable. What am I doing wrong? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Dovecot LMTP rejects all users as non-existent
by Alexander Harm 09 Mar '18

I'm running Dovecot 2.2.27 (c0f36b0) on Debian Stretch and I'm having some trouble with LMTP delivery from Postfix to Dovecot. The message in the logs is Mar 9 09:21:19 mail postfix/smtpd[3295]: NOQUEUE: reject: RCPT from some.mail.server[1.2.3.4]: 450 4.1.1 <alias(a)my.domain>: Recipient address rejected: unverified address: host my.mail.server[private/dovecot-lmtp] said: 550 5.1.1 <user(a)my.domain> User doesn't exist: user(a)my.domain (in reply to RCPT TO command); from=<someone(a)another.domain> to=<alias(a)my.domain> proto=ESMTP helo=<some.mail.server> However, testing my installation with doveadm works fine: doveadm user -u user(a)my.domain userdb: user(a)my.domain user : user(a)my.domain uid : 5000 gid : 5000 home : /srv/mail/vhosts/my.domain/user doveadm auth test user(a)my.domain passdb: user(a)my.domain auth succeeded I'm using a static userdb and a ldap passdb: # /etc/dovecot/conf.d/auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/srv/mail/vhosts/%d/%n } And my LDAP config reads like this # /etc/dovecot/dovecot-ldap.conf.ext uris = ldap://127.0.0.1 dn = uid=dovecot,ou=services,dc=my,dc=domain dnpass = ********* auth_bind = yes auth_bind_userdn = cn=%u,ou=mail,dc=my,dc=domain ldap_version = 3 base = ou=mail,dc=querco,dc=org deref = never scope = onelevel user_attrs = user_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) pass_attrs = cn=user,userPassword=password pass_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)(cn=%u)) iterate_attrs = cn=user iterate_filter = (&(objectclass=PostfixBookMailAccount)(mailEnabled=TRUE)) Sending the mail straight to user(a)my.domain works. Sending it to another alias works as well. Is there some caching problem and if so how to delete the cache (reboot didn't work)? Any pointers are highly appreciated.

Authentication Problem with dovecot-2.3.0.1
by Odhiambo Washington 08 Mar '18

08 Mar '18

I am a little confused here. I have been running 2.2.34 which I installed in /opt/dovecot2.2 I installed 2.3.0.1 to /opt/dovecot23 I then used config files from /opt/dovecot2.2/etc/dovecot to /opt/dovecot2.3/etc/dovecot and all I did was sed -i.BAK 's/dovecot2.2/dovecot2.3/g'. Dovecot started and was running file. Next, I manually crafted config files for 2.3.0.1 based on the example config files provided which diff-ing those with what I had for 2.2.34. I doub't if I missed something crucial during the process. 1. I realized that I cannot start 2.3.0.1 when I enable submission, since my Exim MTA is already using that port. This persists even if I tell the submission protocol to use a different port than 587. I tested 2587, but it would appear that 587 is hard-coded! 2. I realize that "unix_listener auth-client" service ceased to exist! 3. *I realized that while 2.2.34 runs with default_pass_scheme = MD5-CRYPT, 2.3.0.1 would not run with it.* 4. I have run dovecot -n from my 2.2.x installation and 2.3.x installation and here is the diff from the two files. I am confused why authentication is failing with dovecot-2.3.0.1 when it uses 2.3.x config files using MD5-CRYPT scheme while it is succeeding with dovecot-2.2.34 using the same. *Mar 07 22:30:22 auth: Info: sql(user.name(a)domain.name <user.name(a)domain.name>,192.168.55.97,<4CETl9dmscvAqDdh>): Requested DIGEST-MD5 scheme, but we have only MD5-CRYPT* Maybe the problem is elsewhere???

Hello, I've got dovecot going with postfix and MySQL database for user and domain storage. Dovecot handles the authentication. My last login is not working, does anyone have a table example and configs? I looked at the wiki page on the lastlogin plugin but obviously what I'm doing isn't working, I keep getting message write was unsuccessful for the lastlogin ip. I'd appreciate any help. Thanks.

Authentification fails in dovecot 2.3.0.1
by post＠volker-wysk.de 07 Mar '18

Hi I've upgraded dovecot from 2.2.22 to 2.3.0.1. Now I can't authenticate any longer. My mail client says that the user name and password are rejected by dovecot. I get this line in /var/log/auth.log: Mar 6 19:28:02 desktop auth: PAM audit_log_acct_message() failed: Operation not permitted And this in /var/log/dovecot.log: Mar 06 19:28:02 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 06 19:28:02 auth: Debug: auth client connected (pid=5615) Mar 06 19:28:02 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=ggZPmsJmIoh/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=993 rport=34850 local_ Mar 06 19:28:02 auth-worker(5617): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): lookup service=dovecot Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): #1/1 style=1 msg=Password: Mar 06 19:28:02 auth-worker(5617): Info: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): pam_authenticate() failed: System error Mar 06 19:28:04 auth: Debug: client passdb out: FAIL 1 user=v Mar 06 19:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts in 4 secs): user=<v>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<ggZPmsJmIoh/AAAB> Now it seems I can't go back to 2.2.22 as well: https://wiki2.dovecot.org/Upgrading/2.3 says "Downgrading is possible to v2.2.27 and later.

AppArmor profile for Dovecot on Debian Stretch
by André Rodier 07 Mar '18

07 Mar '18

Hello all, Is there any guide to help in the configuration of Dovecot for AppArmor on Debian / Ubuntu ? Or maybe does any of you already have something that works? I am actually adding AppArmor on an email server project, and I had some trouble with the versions from Debian. I would like to avoid - if possible - the long try and error process for each Dovecot executable. I am using IMAP, LMTP, Sieve and ManageSieve, with LDAP users. The full project reference is here: https://github.com/progmaticltd/homebox ii dovecot-core 1:2.2.27-3+deb9u2 amd64 ii dovecot-imapd 1:2.2.27-3+deb9u2 amd64 ii dovecot-ldap 1:2.2.27-3+deb9u2 amd64 ii dovecot-lmtpd 1:2.2.27-3+deb9u2 amd64 ii dovecot-managesieved 1:2.2.27-3+deb9u2 amd64 ii dovecot-pop3d 1:2.2.27-3+deb9u2 amd64 ii dovecot-sieve 1:2.2.27-3+deb9u2 amd64 Thanks for your advices André

Mail addresses with quotes + Postfix
by Philipp Berger 07 Mar '18

07 Mar '18

Dear all, I have a working setup with Postfix + Dovecot, storing users in a MySQL table. I ran into problems setting up and using a mail address like a"@"b(a)mydomain.tld, which by RFC should be valid, but leads to problems in Dovecot. From my debugging, I can see that on the lookup, Dovecot replaces %n with "a" (quotes added by me) and %d with "b(a)mydomain.tld" (quotes added by me). So the original quotes are gone, and the domain/user split is incorrect. I am not sure of Postfix passes the address without quotes to Dovecot or whether Dovecot can not handle quotes correctly, but I was hoping that someone with more insight into Dovecot could help me out here. System Info: Debian 9, Postifx 3.1.6-0+deb9u1, Dovecot 2.2.27-3+deb9u1 Postfix master.cf for Dovecot: dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/lib/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} I am grateful for any hints :) Thank you in advance, kind regards, Philipp

extra IMAP folders: how to make all clients use the same Sent folder?
by Stanislaw Findeisen 07 Mar '18

07 Mar '18

Dear All I have just setup IMAP with Maildir, but unfortunately some clients create their own folders instead of using those specified in 15-mailboxes.conf . What could be the reason? Here's what it looks like: > B list "" * > * LIST (\HasNoChildren \Sent) "." "Sent Messages" > * LIST (\HasNoChildren) "." Gesendet > * LIST (\HasNoChildren) "." Entw&APw-rfe > * LIST (\HasNoChildren \Trash) "." Trash > * LIST (\HasNoChildren) "." Papierkorb > * LIST (\HasNoChildren \Drafts) "." Drafts > * LIST (\HasNoChildren \Sent) "." Sent > * LIST (\HasNoChildren) "." Ausgang > * LIST (\HasNoChildren \Junk) "." Junk > * LIST (\HasNoChildren) "." INBOX > B OK List completed. Here for example "Gesendet" (meaning "Sent" in German) is a folder created by some Android client app. This app uses it to store its sent mail, while another client uses the Sent folder. Also, is it correct that all those folders (both pre-made and extra) get created directly in the user's maildir, alongside cur, new, tmp and Dovecot index files? Shouldn't there be any subdir? > # dovecot --version > 2.2.13 Thanks! Stanisław

requiring a full fqdn for authentication

Hello, I'm using dovecot to do postfix authentication. I'm trying to get dovecot to require a complete email address as a login. Currently I can log in by either a username or fqdn.

This is the whole idea behind imap, to be able to do work while off-line and sync changes when on-line or I get it wrong ? thanks anyway George

sieve vacation alias handling problem
by Karol Augustin 06 Mar '18

06 Mar '18

Hi, I am using Dovecot LDA as LMTP renders envelope extension unusable. The problem I have noticed is that when user has multiple aliases sieve responds to all of them, not only to :addresses specified. >From testing it seems that :addresses only adds addresses to the list of "known" emails to check against. It is not limiting it. As I understand, sieve should check if To: header is consistent with addresses known to be users. But how Dovecot knows about aliases assigned to the user? >From my testing if header To: address is consistent with envelope To: address the reply is fired. I have sieve_vacation_use_original_recipient left at it's default value (no), so that shouldn't be the case. Now if user address(a)example.com has alias alias(a)example.com specified, the vacation reply will be sent to email addressed to alias(a)example.com, which is weird, because this behavior should be enabled by switching sieve_vacation_use_original_recipient to yes. When user receives an email that was originally sent to his gmail account (forwarded) there is no reply. If I add gmail address to :addresses reply is generated as expected. So my main question is if this is expected? I would like to enable only delivery to primary address and to + extensions to that address by default. I think that it might be that Postfix is expanding aliases and passing the final recipient (as to=<XXX>) to dovecot. Then dovecot is using that address to check for explicit delivery, but something fails, as this address is obviously not in To: header. So it looks like orig_to has to be used as well which should be disabled by sieve_vacation_use_original_recipient? My address is: karol(a)augustin.pl, alias is: carol(a)augustin.pl Mar 2 12:37:32 mail dovecot: lda(karol(a)augustin.pl): sieve: msgid=<3ba0578a5f6b170e942b5bac1b19be36(a)posteo.net>: sent vacation response to <sender(a)example.com> Mar 2 12:37:32 mail postfix/qmgr[4744]: 3zt82h4CG4z2xlw: from=<>, size=732, nrcpt=1 (queue active) Mar 2 12:37:32 mail dovecot: lda(karol(a)augustin.pl): sieve: msgid=<3ba0578a5f6b170e942b5bac1b19be36(a)posteo.net>: stored mail into mailbox 'INBOX' Mar 2 12:37:32 mail postfix/pipe[8793]: 3zt82f3x4xz2xmw: to=<karol(a)augustin.pl>, orig_to=<carol(a)augustin.pl>, relay=dovecot, delay=2.2, delays=2.2/0/0/0.06, dsn=2.0.0, status=sent (delivered via dovecot service) Forward from from gmail: Mar 2 11:38:19 mail postfix/qmgr[4744]: 3zt6kL1yF7z2xgg: from=<karolaug+caf_=karol=augustin.pl(a)gmail.com>, size=5831, nrcpt=1 (queue active) Mar 2 11:38:19 mail dovecot: lda(karol(a)augustin.pl): sieve: msgid=<e610a47934f9aabb31f833c025075cff(a)posteo.net>: discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers (recipient=<karol(a)augustin.pl>, and additional `:addresses' are specified) Mar 2 11:38:19 mail dovecot: lda(karol(a)augustin.pl): sieve: msgid=<e610a47934f9aabb31f833c025075cff(a)posteo.net>: stored mail into mailbox 'INBOX' Mar 2 11:38:19 mail postfix/pipe[5362]: 3zt6kL1yF7z2xgg: to=<karol(a)augustin.pl>, relay=dovecot, delay=1.3, delays=1.2/0/0/0.05, dsn=2.0.0, status=sent (delivered via dovecot service) from my master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -f ${sender} -a ${original_recipient} -d ${user}@${nexthop} Thanks, Karol -- Karol Augustin karol(a)augustin.pl http://karolaugustin.pl/ +353 85 775 5312

I suspect that the "return" keyword should be dropped from both functions. Thoughts?

Thanks, that means that outlook is useless as an Imap client then . This is the whole idea behind imap, to be able to do work while off-line and sync changes when on-line or I get it wrong ? thanks anyway George

LMTP delivery segfaults when user is over quota.
by Reio Remma 06 Mar '18

06 Mar '18

Hello! I'm having crashes with LMTP delivery when user is over quota on the latest CentOS 7.4 with the latest Dovecot 2.3.0.1 from Dovecot repo. I see the issue has been fixed on January 17, but it doesn't seem to have made it into 2.3.0.1 (I compared with the source from https://dovecot.org/releases/2.3/dovecot-2.3.0.1.tar.gz) https://github.com/dovecot/core/commit/2bf919786518d138cc07d9cc21e14ad5e07e… I also noticed a similar construct being used on line 465 (rcpt->rcpt.rcpt->path) that was causing the segfault on the above commit on line 136. struct smtp_address *rcpt_to = rcpt->rcpt.rcpt->path; Should that also use rcpt->rcpt.path; ? Thanks from the other side of the gulf! Reio

Deprecations for schema.xml and newest Solr version (7.2.x)
by TG Servers 05 Mar '18

05 Mar '18

Hi, the schema.xml example provided for dovecot in /usr/share/doc/dovecot-<verison> does not work anymore with the newest Solr Version (as I know of 7.2.x) because some field classes and filter classes are deprecated in this version. The changes (according to the Solr documentation) would have to be : In the index analyzer : <fieldType name="long" class="solr.TrieLongField" /> into <fieldType name="long" class="solr.LongPointField" /> ......... <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/> into <filter class="solr.WordDelimiterGraphFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/> and because this is used in the index analyzer it has to be followed by <filter class="solr.FlattenGraphFilterFactory"/> .............. In the query analyzer : <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> into <filter class="solr.SynonymGraphFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> ............... <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/> into <filter class="solr.WordDelimiterGraphFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/> ......... Don't know if you want to mention this somewhere in your docs. Cheers, Thomas

getmail, dovecot, virtual users
by David Mehler 05 Mar '18

05 Mar '18

Hello, I've got a dovecot setup with virtual users coming from a MySQL database. The only system user I have is the vmail owner of the email store. What i'd like to do is use the program getmail to back up my gmail account and place that in my user's virtual mail store. I'm having issues making the configuration file and where to put it. Should it go in the virtual user's home directory or somewhere else and run by which user root or the vmail user? If anyone has this working any suggestions appreciated. Thanks. Dave.

Outlook 2016 & IMAP Trouble with dovecot
by G A 05 Mar '18

05 Mar '18

Reposting since it went under another thread somehow... Hello List, I'm facing an issue with dovecot (2.2.27) IMAP and Outlook as a client. I have some users that use Outlook (2016) as a client . One of them has a desktop PC in the office and a laptop machine which I've setup some days ago . The user did some work, during the weekend, in his laptop (filling messages into IMAP folders) and to his (and mine) surprise, today in the office he saw that none of his work is reflected on the server. Messages are not where they supposed to be .Tomorrow he will bring the laptop over to check, but I have seen this problem again in the past again with outlook 2016 as a client (specifically I've had a user which during work he was deleting or renaming folders which appear fine on his copy of outlook (ost) but not on the server). Anyone has any experience with dovecot and outlook and related problems ? thanks in advance George

Virtual question
by LuKreme 03 Mar '18

03 Mar '18

“For each virtual directory you need to create a dovecot-virtual file. Its syntax is like:” OK, where does this file get created? Say I want the users to have a virtual mailbox that is messages received in the last month, does that file go into each user' s Maildir path? It sounds like I have to create a virtual folder for each user, then any folders inside that folders, and then the config files in each of the sub folders. user1/Maildir/virtual/month/dovecot-virtual user1/Maildir/virtual/week/dovecot-virtual user1/Maildir/virtual/flagged/dovecot-virtual user1/Maildir/virtual/Amazon/dovecot-virtual user2/Maildir/virtual/month/dovecot-virtual user2/Maildir/virtual/week/dovecot-virtual user2/Maildir/virtual/flagged/dovecot-virtual user2/Maildir/virtual/Amazon/dovecot-virtual Yes? If so, is there anyway to have a "global”virtual that applies to all users (but not that unifies the mail between users or anything like that). Also, will virtual mailboxes show up automatically for the user in the folder list or will they have to specifically subscribe to them? (Assuming they use a client that allows subscribing instead of auto showing all mailboxes like iOS). ˜kremels/ $ cat Maildir/virtual/month/dovecot-vitual # ~/Maildir/virtual/month/dovecot-virtual INBOX work/* all younger 2678400 That should create a mailbox "month” in a folder named "virtual” that shows all the messages from the last 31d, yes? And I should be able to access that mailbox in a MUA like Roundcube or <spit>Thunderbird? -- My main job is trying to come up with new and innovative and effective ways to reject even more mail. I'm up to about 97% now.

Debian: Dovecot 2.3.0.1 won't start if dovecot-pop3d is missing
by Markus Schönhaber 03 Mar '18

03 Mar '18

Hello, given a Debian 9 system with Dovecot 2.2.34 installed from self-built packages made from the official tarball combined with Stephan Bosch's debian files (upgraded multiple times from packages made in a similar way). Today, I updated this system to 2.3.0.1 from the official repository at repo.dovecot.org. After the update, dovecot wouldn't start because of: > dovecot: master: Fatal: service(pop3) access(/usr/lib/dovecot/pop3) failed: No such file or directory Obviously, installing the dovecot-pop3d package, which provides the pop3 binary, made the error go away. Nevertheless, until v. 2.2.34 not installing the pop3 binary had never been a problem. Trying to solve this, I even commented the following sections in the config (which previously hadn't caused problems since the lines defining the ports etc. had already been commented): > 10-master.conf: > service pop3-login { > inet_listener pop3 { > #port = 110 > } > inet_listener pop3s { > #port = 995 > #ssl = yes > } > } > service pop3 { > # Max. number of POP3 processes (connections) > #process_limit = 1024 > } > 10-director.conf: > service pop3-login { > #executable = pop3-login director > } After those changes I had the configuration shown below, which produced the described error. Why would Dovecot insist that the pop3 binary has to exist on the system?

Another remark: I have installed the new version from the PPA provided by dovecot.org: deb https://repo.dovecot.org/ce-2.3-latest/ubuntu/xenial xenial main Before (2.2.22) I had installed it from the ubuntu (canonical) package sources - and not the PPA provided by dovecot.org.

Hi, I'm using autoexpunge to clean my users' Trash and Spam mailboxes. But I'm also using lazy_expunge to keep a copy of deleted messages.

Released Pigeonhole v0.4.22 for Dovecot v2.2.34.
by Stephan Bosch 01 Mar '18

01 Mar '18

Hello Dovecot users, Here is a new Pigeonhole release that goes with the new Dovecot v2.2.34 release. This release is not strictly necessary, as previous versions should be usable as well. This release only contains bugfixes. Changelog v0.4.22: - Fixed filesystem path handling problem: sieve plugin could have assert-crashed with specific path lengths with: "Panic: file realpath.c: line 86 (path_normalize): assertion failed: (npath_pos + 1 < npath + asize)". - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. - editheader extension: Extensively reworked the low-level implementation of adding and removing headers. This solves a few integer arithmetic problems reported by Clang runtime checks, but also improves code structure and reliability in general. - imapsieve: Fix assert crash occurring when selected messages are expunged concurrently by the time Sieve filter is to be applied. - imap4flags extension: Fix binary byte-code corruption occurring when the setflag, addflag, or removeflag command's flag-list is a variable. - enotify extension: mailto method: Fixed parsing of mailto URI with only a header part. - enotify extension: mailto method: Make sure "From:" header is set to a usable address and not "(null)". - Fixed writing address headers to outgoing messages. It sometimes erroneously applied another layer of MIME header encoding. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.22.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.22.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

question about quota setting with postfix and dovecot

Dear dovecot-list, I have questions regarding setting up quota with postfix(Maildir format)+ dovect. My main point of the question is to know how the user password is used in quota in this case. Please see the below configuration info and my questions are in the bottom. Here are what have been done: <Postfix side configuration> /etc/postfix/main.cf: ----- myhostname = mail.example.com mydomain = example.com myorigin = $mydomain inet_interfaces = all mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain home_mailbox = Maildir/ mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" -d "$USER" <--Add ----- <Dovecot side configuration> 1. /etc/dovecot/conf.d/10-auth.conf: #!include auth-system.conf.ext #!include auth-sql.conf.ext #!include auth-ldap.conf.ext !include auth-passwdfile.conf.ext <---Only enabled #!include auth-checkpassword.conf.ext #!include auth-vpopmail.conf.ext #!include auth-static.conf.ext 2. /etc/dovecot/conf.d/10-master.conf service auth { snip/ unix_listener auth-userdb { mode = 0666 <---The permission for userdb 666 #user = #group = snip/ 3. /etc/dovecot/conf.d/10-mail.conf: mail_location = maildir:~/Maildir snip/ mail_plugins = $mail_plugins quota <---set the plugin snip/ 4. /etc/dovecot/conf.d/15-lda.conf: snip/ postmaster_address = root(a)example.com <---Add postmaster snip/ protocol lda { mail_plugins = $mail_plugins <--set the plugin } 5. /etc/dovecot/conf.d/20-imap.conf: protocol imap { mail_plugins = $mail_plugins imap_quota <--set the plugin snip/ 6. /etc/dovecot/conf.d/20-pop3.conf: snip/ protocol pop3 { mail_plugins = $mail_plugins quota <--set the plugin snip/ 7. /etc/dovecot/conf.d/90-quota.conf: plugin { <--set global quota quota = maildir:<User quota> quota_rule = *:storage=100M quota_rule2 = Trash:storage=+100M } 8. /etc/dovecot/conf.d/auth-passwdfile.conf.ext: snip/ passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users <--Path for passwdfile } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users } snip/ 9. /etc/dovecot/users: test004:{SSHA256}hFxB8tbyZrCCcwZKDaQEiUfojbRovOq8ECU0syPHQTCY0233:18222:18222::/home/test004::userdb_quota_rule=*:storage=1M test005:{SSHA256}hFxB8tbyZrCCcwZKDaQEiUfojbRovOq8ECU0syPHQTCY0233:18223:18223::/home/test005::userdb_quota_rule=*:storage=1M test006:{SSHA256}hFxB8tbyZrCCcwZKDaQEiUfojbRovOq8ECU0syPHQTCY0233:18224:18224::/home/test006::userdb_quota_rule=*:storage=1M Note:The hashed password is created running the blow command: # doveadm pw -s ssha256 10. /etc/dovecot/dovecot.conf: snip/ protocols = imap pop3 <--Available protocols snip/ 11. # service postfix restart # service dovcot restart Question: 1./etc/dovecot/users is supposed to be seen instead of /etc/passwd for authentification of imap and pops in receiving emails, isn't it? 2.If the answer for above question 1 is 'YES', then doesn't it require to get all password in /etc/passwd hashed for each user and place all of them into /etc/dovecot/users? 3.If the answer for above question 1 is 'NO', then what the hashed-password in /etc/dovcot/users such as {SSHA256}hFX... used for? Excuse me if those are silly questions, but I am not a dovecot person and would very much appreciate it if anyone would kindly give me a hand on this. Regards, Masaharu Kawada

Using virtual folders with younger and index files
by Rob Hoelz 01 Mar '18

01 Mar '18

Hi list, I just encountered a problem while using dovecot's Virtual plugin with 2.3.0. I managed to solve the issue, but I wanted to bring it to the attention of others on the list to see if there exists a better solution, if I found a bug, or if it's just a matter of updating documentation. I have a virtual folder to get the most recent two weeks of mails; it looks something like this: > INBOX > all younger 1209600 I made this folder back in October. Lately, I started to notice that the virtual folder had a surprising amount of mail in it - I don't get 1,000 e-mails per week! After some doveadm commands, I realized that e-mails from October were still present in my virtual folder! Updating the dovecot-virtual would clear away e-mails older than two weeks (I needed to actually introduce a change, even if it was just whitespace - just touching the file didn't update things), and removing the dovecot index file also cleared things away. In then end, I ended up just telling dovecot to disable on-disk indexes for that folder. I created this folder based on the examples on https://wiki.dovecot.org/Plugins/Virtual - I'm wondering if I found a bug or if that page should be changed to recommend disabling on-disk indexes when using certain search query filters such as "younger". If the latter, I can always make the change - just let me know! -Rob

Re: Quota status to postfix in distributed environment (Karol Augustin)
by SAAHIL IFTEKHAR 28 Feb '18

28 Feb '18

Hi Karol Thanks for taking time to go through the email and replying. I'll rewrite the issue again --> For example consider there two nodes. These each having their postfix and dovecot. I am trying to implement quota status to postfix to both the below cases:- case 1) mail sent within the node case 2) mail sent across the nodes In case 1 the postfix will query the dovecot of same node white in case 2 it will query the dovecot of other node. But suppose I am sending mail within the node and dovecot in other node is down. Mail will not go within the node. Even it will not defer also. This is evident from the logs(in last sections). I'll try to work suggestions you have given in mysetup though and post the relevant output. But if you have any other suggestion regarding what i have wrote just now. please let me know.

I want to point out that the reason from the problem can be found out from logs(the end section). The "check_policy_service" in main.cf of postfix is the problem according to me. This configuration as a part of quota staus to postfix configuration. I hope many have went through this scenario or similar. So I am hoping to get some help for the same.

But I am not able to resolve the issue even after searching solution on internet and trying different hit and trials by myself. I want that if i am sending email to any node or within node, the configuration relating to "check _policy_service" for other node does not interfere and mail goes properly. At the same time I can also fetch quota status from other nodes. > > If I can get any help regarding this it will be really appreciable as I have tried a lot of options already. > Your problem is that if the dovecot is unreachable Postfix can't check the quota for the user. http://www.postfix.org/SMTPD_POLICY_README.html explains how to resolve this problem: smtpd_policy_service_default_action (default: 451 4.3.5 Server configuration problem): The default action when an SMTPD policy service request fails. Available with Postfix 3.0 and later. The default action when an SMTPD policy service request fails. Specify "DUNNO" to behave as if the failed SMTPD policy service request was not sent, and to continue processing other access restrictions, if any. You can configure it per policy also. The issue you might encounter with this setup is that if both of your dovecot nodes are unreachable Postfix will accept the e-mail and try to deliver it. When the nodes come online it will fail if the user is over quota and generate bounce to the envelope sender of the message, which might produce backscatter. I resolved this problem by keeping quota information in Mysql table and using custom policy server to check if user is allowed to receive more e-mail. Also this approach might not work with aliases and other redirections, the e-mail address checked by smtpd policy is the one before alias expansion. You should check if it suits your environment.

dovecot.index.pvt reset, view is now inconsistent
by Rupert Gallagher 28 Feb '18

28 Feb '18

Problem solved by going in manually. The log message appears for empty "public" folders. Say, you have a folder X with subfolder Y, where X does not contain any e-mail. The log message disappears if you drop an email into X, then remove it. Puf, gone! So, there seems to be a baby bug in how dovecot manages the index in this case.

BUG: Error: dovecot.index.pvt reset, view is now inconsistent when shared folder is new and empty
by Marco Giunta 28 Feb '18

28 Feb '18

Hi, I'm using Dovecot 2.2.33.2 on a RHEL 7, new installation. My log is full of : Error: INDEX_FOLDER/dovecot.index.pvt reset, view is now inconsistent or Error: INDEX_FOLDER/dovecot.index.pvt view is inconsistent when shared folder is never touched and empty. UserA share XXXXX folder with UserB, if XXXXX folder is new (never touched) and empty every time UserB looks in that folder, an error appears in log file. If UserA copy a mail in XXXXX folder, no more errors. If UserA (or UserB) delete all mails in XXXXX folder (the folder is empty again), no more errors. So the errors appear when UserB access a new (never touched) shared empty folder; if the folder is empty, but not new (p.e. UserA has already copied and deleted mails in that folder) error is logged only once. Attached my configuration.

Out of memory on lmtp vsz_limit
by Terence Lau 28 Feb '18

28 Feb '18

Hi, We've been getting these types or errors for quite a while now ... Fatal: master: service(lmtp): child 63477 returned error 83 (Out of memory (service lmtp { vsz_limit=4096 MB }, you may need to increase it) ... and these errors have been decreasing in occurrence as we increased the default_vsz_limit. Which is good but I would like to get some advice on how I could possibly eliminate the errors. We have an internal smtp server (postfix 3.1.0) that has the config "always_bcc=archive(a)company.com" over lmtp. This mailbox is on a separate dovecot server with the following config (please let me know if the full config is required): # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-109-generic x86_64 Ubuntu 16.04.1 LTS ext4 default_vsz_limit = 4 G mail_location = maildir:/home/vmail/%d/%n protocols = " imap lmtp pop3" service lmtp { inet_listener lmtp { port = 24 } } userdb { args = username_format=%u /etc/dovecot/users default_fields = uid=vmail gid=vmail home=/home/vmail/%d/%n driver = passwd-file } protocol lmtp { mail_plugins = } Since we discovered the errors, we've been increasing the default_vsz_limit to 1G, then 2G and now 4G (Server has 6GB of memory). These errors occur whenever a large number of emails get sent around the same time to our smtp server. This causes the dovecot server to start crunching CPU and Memory. Load average goes through the roof and takes some time to come back down as the smtp queue clears itself. This mailbox is obviously very large but we have a script that runs daily to delete any emails older than a month: find /home/vmail/company.com/archive/new/ -type f -mtime +30 -exec rm {} \; find /home/vmail/company.com/archive/cur/ -type f -mtime +30 -exec rm {} \; Still, the mailbox has on average of just under 300,000 emails. No one accesses this mailbox with an email client, not until we need to dig something up. And this has only happen once. So the emails pretty much never get read/process by a user. Now that we've increased the default_vsz_limit to 4G, the occurrence of these errors has reduced considerably. But they still happen occasionally. Short of increasing the memory further, are there any other options I have? Thanks. [https://www.royhill.com.au/email/Emalisignaturecurrent.jpg]

Quota status to postfix in distributed environment
by SAAHIL IFTEKHAR 27 Feb '18

27 Feb '18

Hi I have implemented Quota status to postfix in our setup. I have an imap server (dovecot) and mail server (postfix) in every node. I am able to send quota status to postfix and mails are rejected after 100% mail quota is crossed. This rejection is happening both in across the nodes and within the nodes. The problem is if I am sending mails to any node and if any other node's dovecot is down, mails are not going. For example, I am sending an email within the system but if some other node's dovecot is down then email within the system also will not go. My dovecot version is 2.2.10. My postfix version is 2.1.10. *doveconf -n output is below:-* # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-514.el7.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.3 (Maipo) xfs

Hi Actually, the requirement is such that we have to work with this version only. I want to point out that the reason from the problem can be found out from logs(the end section). The "check_policy_service" in main.cf of postfix is the problem according to me. This configuration as a part of quota staus to postfix configuration. I hope many have went through this scenario or similar. So I am hoping to get some help for the same.

Really slow IMAP performance
by Neil Jerram 26 Feb '18

26 Feb '18

Please could you help me to understand and fix why my dovecot IMAP performance is so bad? I've read through a lot of the performance-related material on the website, but I don't think that any of it could account for slowness at the level that I am seeing. The simplest scenario is moving a message from my Inbox to another IMAP folder. Using Gnus as the client, the whole UI freezes for about 2 minutes (which I assume is until the move is complete), and journalctl on the dovecot server says: Feb 24 10:24:24 arudy dovecot[1712]: imap(neil): Warning: Transaction log file /home/neil/dovecot-mail/.imap/INBOX/dovecot.index.log was locked for 98 seconds (Mailbox was synchronized) or the same message with (rotating while syncing). There must be something badly wrong in my setup, or perhaps in the spec of the server that dovecot is running on. What should I look at to start understanding this better? Many thanks - Neil

understanding dovecot director passdb configuration
by Kalyana sundaram 26 Feb '18

26 Feb '18

Hey All I am very new to dovecot ecosystem. Found the software really robust and secure. Kudos to the team!!! We are setting up dovecot imap servers sharing a single nfs mount point. So to avoid nfs cache issues, we are setting up dovecot director. We are using dovecot version 2.2.10. While going through the documentation of dovecot director I stumbled across the following lines in passdb configuration https://wiki2.dovecot.org/Director "Note that while this is the simplest director configuration, users will be assigned to a backend before they have been authenticated. A director configured this way can be attacked by sending it a large number of unknown users. To prevent this, the director should be configured to authenticate the user and might make use of a master password to log into the backend servers." I understand on static passdb config dovecot assigns a user to a machine in the list of backends by using md5(username)%number_of_mail_servers. But other than this calculation it does not incur any other resources. It does have tcp connection with the system which is trying to do bruteforce. If we move to authenticating users directly at the director server, the director servers imap-login director service should be anyways loaded on an attack. Is it anything to do that the imap-login will contact auth process asynchronously and keep itself free? I am pretty sure I am overlooking some point on the above statement. Can somebody throw some light on that? -- Kalyanasundaram http://blogs.eskratch.com/ https://github.com/kalyanceg/

imap-login director is not restarted after each auth request
by Kalyana sundaram 26 Feb '18

26 Feb '18

Hi imap-login by default in mail server is restarted after every login request keeping security in mind to avoid leak of critical data. But in a director config, the imap-login director process is not restarted on each auth request. Can somebody explain why this design decision is taken? -- Kalyanasundaram http://blogs.eskratch.com/ https://github.com/kalyanceg/

2.2.33.2 - Virtual Mailbox Issue bug maybe ?
by Matt Bryant 25 Feb '18

25 Feb '18

Been experimenting with virtual mailbox and have a question :- I have defined 2 virtual mailboxes 'all' and 'combined' as follows ... virtual/all/dovecot-virtual virtual/combined inthread refs x-mailbox INBOX virtual/combined/dovecot-virtual !INBOX INBOX/Sent INBOX/Drafts all When new mail comes I would assume that both virtual mailboxes should actually see the message but whilst an imap search command gets a result in the virtual/combined for some reason not every message is seen in virtual all - so was wondering what exactly does 'inthread refs x-mailbox INBOX' do ? I would have thought new mail to inbox would just have a thread of 1 and be seen. If i remove the indexes from virtual then the messages appear so am thinking something not quite triggering an action. Any ideas ? What can I do to try and track down where problem lies or am i misunderstanding what 'inthread refs x-mailbox INBOX' should do ???? == 8< ========== # doveconf -n # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) doveconf: Warning: service auth { client_limit=5000 } is lower than required under max. load (26096) doveconf: Warning: service anvil { client_limit=5000 } is lower than required under max. load (9715) # OS: Linux 3.10.0-693.11.6.el7.x86_64 x86_64 CentOS Linux release 7.3.1611 (Core) auth_cache_negative_ttl = 2 mins auth_cache_ttl = 3 mins auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_worker_max_count = 100 default_client_limit = 8192 default_process_limit = 8192 default_vsz_limit = 512 M disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags imap_idle_notify_interval = 1 mins login_greeting = IMAP/POP3 ready - us11-001dm mail_attachment_dir = /var/mail/sis/%Ld mail_cache_min_mail_count = 5 mail_debug = yes mail_plugins = " quota virtual" mailbox_list_index = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext vacation-seconds spamtest spamtestplus editheader mbox_write_locks = fcntl mmap_disable = yes namespace inbox { inbox = yes list = yes location = mailbox Archive { auto = create special_use = \Archive } mailbox Drafts { auto = create special_use = \Drafts } mailbox Sent { auto = create special_use = \Sent } mailbox Spam { auto = create special_use = \Junk } mailbox Trash { auto = create special_use = \Trash } prefix = INBOX/ separator = / type = private } namespace virtual { list = no location = virtual:/var/lib/mail/dovecot/virtual:INDEX=~/virtual prefix = virtual/ separator = / type = private } passdb { args = /etc/dovecot/sql_users.conf driver = sql } passdb { args = /etc/dovecot/sql_admin.conf driver = sql } plugin { mail_log_events = delete expunge mail_log_fields = uid box msgid size quota = dict:UserQuota::file:%h/dovecot-quota quota_rule2 = INBOX/Trash:storage=+10%% sieve = file:~/sieve/user;active=~/.dovecot.sieve sieve_default = file:/var/lib/mail/dovecot/sieve/default.sieve sieve_default_name = default sieve_editheader_max_header_size = 1k sieve_extensions = +spamtest +spamtestplus +editheader +vacation-seconds sieve_global = file:/var/lib/mail/dovecot/sieve sieve_quota_max_scripts = 5 sieve_spamtest_max_value = 200 sieve_spamtest_status_header = X-spam-score-int: -?([[:digit:]]+) sieve_spamtest_status_type = score sieve_vacation_default_period = 10d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1s } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_fast_size_lookups = yes protocols = imap pop3 lmtp sieve service anvil { client_limit = 5000 } service auth-worker { user = $default_internal_user } service auth { client_limit = 5000 unix_listener auth_client { mode = 0660 user = exim } } service doveadm { client_limit = 10 inet_listener { address = * port = 4000 } process_limit = 100 process_min_avail = 10 service_count = 1 } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 500 process_min_avail = 10 service_count = 1 } service imap { executable = imap postlogin process_limit = 500 } service managesieve-login { inet_listener sieve { port = 4190 } process_limit = 20 process_min_avail = 10 service_count = 1 } service managesieve { process_limit = 1024 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } process_limit = 1000 process_min_avail = 5 service_count = 1 } service pop3 { process_limit = 500 } service postlogin { executable = script-login -d rawlog } shutdown_clients = no ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecotl.com.pem ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = /etc/dovecot/sql_users.conf driver = sql } protocol imap { imap_capability = +SPECIAL-USE mail_max_userip_connections = 50 mail_plugins = " quota virtual imap_quota" } protocol pop3 { mail_max_userip_connections = 20 mail_plugins = " quota virtual" } protocol lmtp { auth_username_format = %Lu mail_plugins = " quota virtual sieve quota" postmaster_address = mailer-daemon } ======= 8< ========== The below were searches in performed in the two mailboxes .. showing the found/not found status. search in vritual/all ? search header Message-ID < 5A8663D6.5000704(a)the-bryants.net <mailto:5A8663D6.5000704@the-bryants.net> > * SEARCH ?

Dovecot With DSpam AntiSpam Plugin Replacement With Sieve
by colinh＠nxtgn.com 25 Feb '18

25 Feb '18

Hello I have recently had to rebuild my email server, it is a small server for my various email accounts and I also host the email for a clients business. Switched to Dovecot from Courier many years ago, and it has been a very reliable solution With the new rebuild I have updated it to Dovecot 2.2.33.2 with PigeonHole 4.21, it runs DSpam 3.10.2 to scan and tag all incoming mails as Spam or not then a Sieve rule to put the Spam emails into the Spam folder, I was also using the DSpam Antispam plugin to enable moving messages from one folder to another to teach failures to DSpam, this works well for my and my client. Doing the rebuild I saw that the AntiSpam plugin had been deprecated and the preferred solution now was to use Sieve Filters, so I implemented that and had struggled with it for a few hours until I finally got it working. It may be something about my setup but I am not sure it is, but the suggested way of doing it here https://wiki.dovecot.org/HowTo/AntispamWithSieve did not work for me and I don't think it was ever going to. Here are the shell scripts and sieve filters that I came up with that work for me, your mileage may vary. I use DSpam as a standalone binary not as a daemon so you may need to add the --client option on the dspam command line in the shell scripts if you run DSpam in daemon mode. === report-spam.sieve === require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.user" "*" { set "userid" "${1}"; if header :matches "X-DSPAM-Signature" "*" { set "signature" "${1}"; } } pipe :copy "learn-spam.sh" [ "${userid}", "${signature}" ]; === report-ham.sieve === require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.mailbox" "*" { set "mailbox" "${1}"; } if string "${mailbox}" "Trash" { stop; } if environment :matches "imap.user" "*" { set "userid" "${1}"; if header :matches "X-DSPAM-Signature" "*" { set "signature" "${1}"; } } pipe :copy "learn-ham.sh" [ "${userid}", "${signature}" ]; === learn-spam.sh === #!/bin/sh exec /usr/local/bin/dspam --user ${1} --signature=${2} --class=spam --source=error === learn-ham.sh === #!/bin/sh exec /usr/local/bin/dspam --user ${1} --signature=${2} --class=innocent --source=error I hope this saves someone some time or gives someone some tips -- Regards Colin

Remove "Duplicate" emails
by ＠lbutlr 24 Feb '18

24 Feb '18

In a quest to remove “duplicate” messages sent to both me and lists I subscribe to I came up with this, which I think should clean out my Archive folder, but I’ve been unable to get it to work for scanning all on my list-user email. $ doveadm -f table fetch -u kremels 'hdr.message-id guid uid hdr.x-listname' mailbox "Archive" | sort| awk 'cnt[$1]++{if (cnt[$1]==2) print prev[$1]; print} {prev[$1]=$0}' |grep -E "[0-9] +$" |awk '{print "doveadm expunge -u kremels MAILBOX-GUID "$2" UID "$3}’ X-listname is a header that my list user applies to each message that comes from a list, and the output is just text to the screen that I can then run manually (I am not confident enough to automatically delete the messages). I include the X-listname header at the end so that I can exclude lines that don’t end in a number, which means the copies sent directly to me are the ones expunged and the ones from the list are preserved. So far so good. But ther are issues. First, even after expunging a message and running doveadm index -u kremels “Archive”, subsequent runs still show the same duplicate messages. Second, what I really want to do is run this over ALL the mailboxes, except for Junk and Sent but if that is possible I can’t find the right syntax. -- "He has all the virtues I dislike and none of the vices I admire."

Stale mailbox lock file
by Raffaele Gambelli 24 Feb '18

24 Feb '18

Hi all, I would like to understand the meaning of "Stale mailbox lock file detected" In index-storage.c (https://mis.dopa.go.th/atmail/server_source/dovecot/src/lib-storage/index/i…) there is this notice "Stale mailbox lock file detected" ... I have a java application which connects via javamail to a dovecot server and I have some anomalies when that message comes. Thanks, bye Raffaele Gambelli

dovecot auth and horde webmail
by David Mehler 24 Feb '18

24 Feb '18

Hello, I'm not sure if this is a Dovecot-specific question, or Postfix or Horde webmail. As Dovecot is used for authenticating both Postfix as well as horde I thought i'd start here. I've got a new horde webmail install going on a FreeBSD 11.1 jail. I've got Dovecot set up so that it appends a domain name if one is not given, so that user and user(a)example.com can both log in. When I logged in with horde webmail I used for the first attempt username with no @example.com suffix. I logged in ok, but couldn't send an email, gave me a weird error no address associated with host. I logged out, logged back in using user(a)example.com the full address, and this time the message sending went through. Any ideas or if this is not a Dovecot question let me know, as that means I'll have two other places to try. Thanks.

Optimizing search performance for mobile devices / web mailer / general - solr plugin config
by Götz Reinicke 23 Feb '18

23 Feb '18

Hi all, we run dovecot for a long time now with no complains from the users … until this week. Some users say, the search in mailfolders from iPhone (which only stores a few mails and search most on the server as I know) or our web mailer (SOGo, which I currently search also on the imap server) is „slow“. As this is sort of individual experience, I was thinking of ways to speed up the search and came across the fts_solr plugin. My question is, can I „just“ configure the its_solg plugin as described at the dovecot wiki? https://wiki.dovecot.org/Plugins/FTS/Solr <https://wiki.dovecot.org/Plugins/FTS/Solr> How difficult is is to set up a solr server for that purpose? As our current mail hardware is not busy at all, is it ok to install Solr on the same hardware/server? May be someone using that setup can give me some hints? And: How hard is it to switch back to the „build in“ default search if we don’t see any benefit from hosting a solr server too. Thanks for feedback and suggestions . Regards . Götz

Multiple SSL-Certificates/Domains setup not working
by Gabriel Kaufmann 23 Feb '18

23 Feb '18

I've tried setting up multiple SSL-Certificates (using letsencrypt) for dovecot on my ubuntu machine. Used dovecot version is 2.2.18. Regarding to official docs this should be working. My test-client (Thunderbird on linux) has been mentioned to be working fine with SNI here: https://wiki.dovecot.org/SSL/SNIClientSupport https://wiki.dovecot.org/SSL/DovecotConfiguration#line-89 > local_name imap.example.org { > ssl_cert = </etc/ssl/certs/imap.example.org.crt > ssl_key = </etc/ssl/private/imap.example.org.key > } > local_name imap.example2.org { > ssl_cert = </etc/ssl/certs/imap.example2.org.crt > ssl_key = </etc/ssl/private/imap.example2.org.key > } Did anyone have success on this (without using multiple IP per Domain)? -- Best regards Gabriel Kaufmann

Auth SEGV on sparc64, alignment problem?
by Chris Ross 23 Feb '18

23 Feb '18

Apologies first for using two addresses, but I can’t currently read my email at distal.com. :-) I was previously running dovecot2-2.2.29.1_2 on FreeBSD 11 on sparc64. Trying to debug a problem I was having with one of my clients, I upgraded to dovecot-2.2.33.2_4 on that same server. However, I cannot connect now, log shows: Feb 20 16:55:00 westeros dovecot: master: Dovecot v2.2.33.2 (d6601f4ec) starting up for imap, pop3, lmtp Feb 20 16:55:31 westeros dovecot: auth: Fatal: master: service(auth): child 25395 killed with signal 11 (core dumped) Feb 20 16:55:31 westeros dovecot: master: Error: service(auth): command startup failed, throttling for 2 secs Feb 20 16:55:31 westeros dovecot: imap-login: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<>, rip=2001::xxx, lip=2001:470:e24c:200::ae25, TLS handshaking, session=<ASDFSAFSADFSAD> Feb 20 16:55:33 westeros dovecot: auth: Fatal: master: service(auth): child 25398 killed with signal 11 (core dumped) Feb 20 16:55:33 westeros dovecot: master: Error: service(auth): command startup failed, throttling for 4 secs Feb 20 16:55:33 westeros dovecot: imap-login: Disconnected: Auth process broken (disconnected before auth was ready, waited 2 secs): user=<>, rip=2001::xxx, lip=2001:470:e24c:200::ae25, session=<d46tyesdy5dsyd> Feb 20 16:55:37 westeros dovecot: master: Error: service(auth): command startup failed, throttling for 8 secs Feb 20 16:55:37 westeros dovecot: auth: Fatal: master: service(auth): child 25400 killed with signal 11 (core dumped) Loading the core file, as described https://www.dovecot.org/bugreport.html , shows the error in libc somewhere: (gdb) bt full #0 __unaligned_load ( p=0x617070656e640e6d <Address 0x617070656e640e6d out of bounds>, size=4) at /usr/src/release-11.1.0/lib/libc/sparc64/sys/__sparc_utrap_align.c:45 val = 0 i = 0 #1 0x00000000109f9f6c in __unaligned_fixup (uf=0x7fdffffee40) at /usr/src/release-11.1.0/lib/libc/sparc64/sys/__sparc_utrap_align.c:78 addr = <value optimized out> val = <value optimized out> insn = 3254807616 sig = <value optimized out> #2 0x00000000109f9d50 in __sparc_utrap (uf=0x7fdffffee40) at /usr/src/release-11.1.0/lib/libc/sparc64/sys/__sparc_utrap.c:100 sig = 272013984 #3 0x000000001094a10c in __sparc_utrap_gen () from /lib/libc.so.7 No symbol table info available. #4 0x000000001094a10c in __sparc_utrap_gen () from /lib/libc.so.7 No symbol table info available. Previous frame identical to this frame (corrupt stack?) (gdb) As this is a sparc64, with 8-byte alignment requirements, I’m guessing that’s the issue. Many a piece of software has failed to respect that and crashed. But, I’m not sure. Does anyone have any suggestions? I’ve built it locally (via ports), so if there are compiler options I can/should try, I certainly can try. Thanks… - Chris

Constant IMAP timeouts/dropouts
by H.E. 23 Feb '18

23 Feb '18

Hello, I've searched and searched for a solution to this problem but continue to come up empty. I have a very generic setup. CentOS Linux 7.3.1611 running on AWS. I installed the QMail toaster from here: http://www.qmailtoaster.com/ ( I had been using Bill Shupp's Qmail Toaster for years and years, but he stopped supporting it.) As such, I did have to convert my Courier mailboxes to Dovecot (no real problem there). I'm using Thunderbird client on Windows and Mac. I have one user (me) using two vpopmail domains with a total of three mailboxes. Each mailbox has about 20 folders which I tag in Thunderbird as "When getting new messages for this account, always check this folder". I might have two or three client machines (at different locations) running at once (desktop and two notebooks) all trying to get mail. The problem is I can't go 5 minutes without Dovecot timing out on me, returning an error in Thunderbird: "Login to server failed" and asks to "enter new password, cancel, or retry" options, or just hanging. The only way to get Dovecot back is to bounce both dovecot and the network via: /bin/systemctl restart dovecot.service ; /bin/systemctl restart network Then I can resume normal activities for a while. It got so bad that I put the above restarts into a cron job running every 5 minutes. But even then the problem persists after a couple of minutes. There's nothing else running on this box. I've already increased both mail_max_userip_connections = 8000 and: protocol imap { mail_max_userip_connections = 8000 mail_plugins = " quota imap_quota" } By the way, the the identical mailbox and client setup, I never had this problem with Courier IMAP. My dovecot -n is pasted below. So I'm at a loss on how to fix this. I have tried adjusting the number of cached Thunderbird connections, and that doesn't change anything. Any help or pointers in the right direction to keep Dovecot connected would be most helpful. Thanks, -hank Here is my dovecot -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-514.26.2.el7.x86_64 x86_64 CentOS Linux release 7.3.1611 (Core) auth_cache_size = 64 M auth_debug_passwords = yes auth_mechanisms = plain login digest-md5 cram-md5 first_valid_gid = 89 first_valid_uid = 89 log_path = /var/log/dovecot.log login_greeting = Dovecot toaster ready. mail_max_userip_connections = 8000 mail_plugins = " quota" namespace { inbox = yes location = prefix = separator = . type = private } passdb { args = cache_key=%u webmail=127.0.0.1 driver = vpopmail } plugin { quota = maildir:ignore=Trash quota_rule = ?:storage=0 } protocols = imap ssl_cert = </var/qmail/control/servercert.pem ssl_dh_parameters_length = 2048 ssl_key = </var/qmail/control/servercert.pem userdb { args = cache_key=%u quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol imap { mail_max_userip_connections = 8000 mail_plugins = " quota imap_quota" } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_fast_size_lookups = yes pop3_lock_session = yes }

I'm using SSL for dovecot, and dovecot kindly warned me on startup that I needed the ssl_dh parameter, which I specified: # grep -P '^ssl_dh' /etc/dovecot/conf.d/10-ssl.conf ssl_dh = </etc/dovecot/dh.pem And I generated the file, as specified in the comment: # openssl dhparam -out /etc/dovecot/dh.pem 4096 The file contains the appropriate headers: # grep -P '^\-' /etc/dovecot/dh.pem -----BEGIN DH PARAMETERS----- -----END DH PARAMETERS----- However, when I restart dovecot (`systemctl restart dovecot`) I get the following error: lmtp(8221): Error: SSL context initialization failed, disabling SSL: Couldn't parse DH parameters: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: DH PARAMETERS This message repeats 5 times (presumably for each dovecot service?). In /var/log/dovecot/imap.log, I see the same error. I even gave permission to the `dh.pem` file for the *vmail* user and group, but that didn't seem to change anything. Any ideas? Thanks.

Authenticating pam and and sql
by ＠lbutlr 22 Feb '18

22 Feb '18

When a sql user logs in, dovecot always tries pam first (used for the local users with home directories) which generates a login failure in the log, before trying sql (virtual users) and allowing the user to login. Since all the pam users login as 'user' and all the sql users login as 'user(a)example.com' is it possible to tell dovecot which method to check based on the username pattern? It's not a big deal, but these errors show up when I am checking my maillog for problems, and I can't really exclude them since I do want to see actual login failures.

"Stale mailbox lock file detected, will override in 0 seconds"
by Raffaele Gambelli 22 Feb '18

22 Feb '18

Hi all dovecot members, I've received this notice from a dovecot server: "Stale mailbox lock file detected, will override in 0 seconds" I would like to know what it means. I've implemented a "Mail Proxy Server" in java, which connects to many accounts and folders, listening for incoming messages or deleted one, it uses the IMAP protocol. I received that message only 5 times in 60 days of logs, last time, in the same time lapse my server has not received three messages, saying differently, the listener (I'm using Javamail which works fine) has not be notified about those new threee messages. So, I would like to find a link between the above dovecot message and the "black-out" which I had, could you help me please? Thanks, bye Raffaele Gambelli WebRainbow® Software Analyst & Developer

exim dovecot sieve
by himbeere＠shinymail.de 22 Feb '18

22 Feb '18

Hello list. I have just a generic question. Exim delivers fine to dovecot-lda. My problems are the logfiles. Whenever I recieve a message Exim writes to dovecot.log as the user who recieves the mail. This forces me to have that logfile world writeable. I don't really like that. How do you guys deal with that? Here my transport: dovecot_delivery: driver = pipe # You may or may not want to add -d $local_part@$domain depending on if you need a userdb lookup done. command = /usr/libexec/dovecot/dovecot-lda -f $sender_address message_prefix = message_suffix = log_output delivery_date_add envelope_to_add return_path_add #group = mail #mode = 0660 temp_errors = 64 : 69 : 70: 71 : 72 : 73 : 74 : 75 : 78 thanks and best regards t.

Shared folders and quota
by Fabian Kuran 20 Feb '18

20 Feb '18

Hi all, we are able to observe a very strange behaviour: User A wants to copy a mail to a shared mailbox of user B. This works like a charme if the quota of user A is lower than the used space of user B. But is the used space of user B higher than the quota size of User A, "User A" is not longer able to copy the message to the shared folder of user B. His IMAP Client says something like "NO OVERQUOTA". # doveadm quota get -u UserA Quota name Type Value Limit % User quota STORAGE 20085 25600 78 User quota MESSAGE 68 - 0 # doveadm quota get -u UserB Quota name Type Value Limit % User quota STORAGE 39963 122880 32 User quota MESSAGE 160 - 0 Is this a known behaviour of dovecot? Is there a way to "disable" quota-handling for shared folders?

Hi, as discussed with cmouse on freenode two days ago please find attached necessary debug information on a crashing imap-login process, that appeared after upgrading to v2.3 (+ sieve). It is a standard setup in combination with postfix and thunderbird, roundcube and K9(Android) as imap clients. Panic happens 5-6 times a day, but no influence on user experience. Unfortunately i have no idea what might be causing it. Let me know if you need more information.

SASL LOGIN mechanism with nopassword
by Patrick Monnerat 18 Feb '18

18 Feb '18

Hi list, I've noticed dovecot pop3 does not request the password with 'AUTH LOGIN' when nopassword is set. dovecot-2.2.18 auth_mechanisms = plain login ssl = required auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = nopassword=yes userdb_uid=vmail userdb_gid=vmail userdb_home=/var/spool/vmail/%d/%n override_fields = password= } userdb { driver = prefetch } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = uid=vmail gid=vmail home=/var/spool/vmail/%d/%n } Although this works perfectly well, skipping the password phase in the SASL LOGIN mechanism deviates from the draft for this mechanism at https://tools.ietf.org/html/draft-murchison-sasl-login-00 I know this document is not normative and has not made its way to a standard. However it does not mention the ability to bypass the password phase. My questions are: - Is the dovecot behavior intentional ? - If not, will you change it (i.e.: to a dummy password request) ? - Are you aware of another server considering the SASL LOGIN password phase as optional ? Please don't tell me to change the config or to use the PLAIN or EXTERNAL mechanism: the real goal of these questions is to know whether this deviance should be supported by a client (more precisely cURL) or not. Thanks in advance for you reply. Patrick

FreeBSD Core dump: PAM authentication with Kerberos credentials (GSSAPI_MIT)
by Ben Woods 18 Feb '18

18 Feb '18

Hi everyone, I have a repeatable core dump when running dovecot on FreeBSD in the specific scenario described below. Dovecot is linked against MIT kerberos in /usr/local/lib/, whilst PAM is linked against Heimdal in /usr/lib/. My expectation was that dovecot authentication using GSSAPI would use MIT kerberos in /usr/local/lib, whereas PAM authentication is independent from dovecot and would therefore use Herimdal in /usr/lib/. What actually seems to occur during PAM authentication is the Heimdal code in /usr/lib/ is initially being used, but part way through it switches to using the MIT kerberos code in /usr/local/lib/. I have reported this bug on the FreeBSD bug tracker here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225818 Any help troubleshooting this issue would be much appreciated. I suspect it has something to do with the CFLAGS and LDFLAGS being used during the build, so I have attached the build log to the FreeBSD bug report. Thanks in advance, Ben SCENARIO: - Build mail/dovecot with option GSSAPI_MIT (link against MIT kerberos from ports rather than Heimdal in base) - Configure dovecot for PAM authentication, using PAM service "imap": $ cat /usr/local/etc/dovecot/conf.d/10-auth.conf auth_mechanisms = plain passdb { driver = pam args = %s } userdb { driver = passwd } - Configure imap pam to authenticate against kerberos (and enable debugging): $ cat /etc/pam.d/imap auth sufficient pam_krb5.so debug account required pam_krb5.so debug RESULT: This results in a crash of the dovecot authentication worker before any kerberos messages are even exchanged. DIAGNOSIS: Reviewing the log output below, my explanation of the backtrace is below (cronological order / newest item last): - Dovecot had successfully performed pam_start(), the necessary pam_set_item(), and called pam_authenticate(pamh, 0) https://github.com/dovecot/core/blob/2.2.33.2/src/auth/passdb-pam.c#L158 - PAM called pam_sm_authenticate() in /usr/lib/libpam/modules/pam_krb5/pam_krb5.c which successfully got the user, ruser, service, principal, password, checked local user, and then ran krb5_get_init_creds_opt_set_default_flags https://github.com/freebsd/freebsd/blob/master/lib/libpam/modules/pam_krb5/… - Heimdal krb5_get_init_creds_opt_set_default_flags ran the Heimdal version of krb5_appdefault_time: https://github.com/freebsd/freebsd/blob/master/crypto/heimdal/lib/krb5/init… - Heimdal function krb5_appdefault_time ran the MIT kerberos version of krb5_appdefault_string: https://github.com/freebsd/freebsd/blob/master/crypto/heimdal/lib/krb5/appd… This is where the code path cross from using the Heimdal code to the MIT kerberos code, which it should not do. I know this, because the GDB backtrace shows the krb5_appdefault_string function called strdup in file appdefault.c:165, but the Heimdal appdefault.c file only has 140 lines. Reviewing the MIT kerberos code, the strdup function is indeed called at appdefault.c:165. Why did the Heimdal appdefault.c code call the MIT kerberos version of krb5_appdefault_string, when the Heimdal version was only 50 lines higher in the same appdefault.c file?

Using director but stick user to a fixed backend
by pw＠wk-serv.de 17 Feb '18

17 Feb '18

Hi everyone, I am using dovecot with a director setup for two backends. I want to add a third backend for use with the apple imap push plugin. Is there a way I can stick some users to this third backend and not using the director feature? Regards Patrick

Sieve to process list mail based on list-ID
by ＠lbutlr 17 Feb '18

17 Feb '18

Before I spend a lot of time trying to replicate a procmail script that automatically sorts list mail into mailboxes based on the List-ID header (and possibly some other data) I thought I'd check if someone had already done this for sieve. Basically, what I do now in procmail is 1. Get the listname from the List-ID header (or List-post/List-owner if no ID) 2. check against a list of list-ids and if the ID is not on the list, send it to spamc and put the message (if not spam) in the INBOX but mark it as seen, otherwise put it in Junk. 3. have some list specific rules (like rewriting reply-to, stripping subjected tags, etc. 4. Drop message in mailbox based no the ID. (so, dovecot mail goes into .dovecot/new but RandomFakelist gets scanned for spam and if it passes, marked read and put in the inbox). I've seen things like: if exists "List-Id" { if header :contains "List-Id" "dovecot.dovecot.org" { fileinto "dovecot"; } elsif header :contains "List-Id" "others-list.example.com" { fileinto "other-list"; } But I am looking for something more generic, along the lines of $myLists = {"dovecot", "postfix", "other-list") if header :contains "List-ID" "<([^\.])+." { $myID $1; } if $myList :contains $myID { if { $myID is other-list { set $myID to Olist; set header "reply-to" to "moderator@users+other@foo.example.net"; } fileinto $myID; } else { send message to spamc and await results; if spam {fileinto "Junk";} else {fileinto "INBOX";} (obviously that's not the code, but it should give an idea of the sorts of things I want to do and would rather not entirely duplicate. Obviously, I don't know if sieve does variables at all (none of the few example scripts I've looked at have them, but then again most procamil scripts don't have them either). Does sieve support that sort of matching?

`mail_crypt` Doesn't Appear to be Working
by jordan.h＠startmail.com 17 Feb '18

17 Feb '18

Dovecot version: 2.2.22 (fe789d2) I generated an EC key from the page https://wiki2.dovecot.org/Plugins/. For reference here's my /etc/dovecot/conf.d/10-mail-crypt.conf file: ---- mail_plugins = $mail_plugins mail_crypt plugin { # mail_crypt_global_private_key = </etc/dovecot/ecprivkey.pem mail_crypt_global_public_key = </etc/dovecot/ecpubkey.pem mail_crypt_save_version = 2 } ---- I saw in a previous message on this mailing list that messages can be encrypted without the private key, so it's stored elsewhere. :-) After restarting dovecot and sending myself a message I found that the message was still unencrypted. Nothing in /var/log/dovecot/*.log files or syslog indicated any problem loading the plugin (I even made some mistakes with the filename beforehand, and errors indicated it was trying to find the plugin). In case in matters dovecot was installed as part of the automated iredmail install (https://iredmail.org) I didn't modify the dovecot.conf file after installation (except for thinking I needed to add `mail_crypt` to `plugins`, then figuring I didn't). Any help is appreciated. Thank you.

Director & Master Users

Hello, I have Director setup to proxy requests to backend servers. This works fine when using "standard" username/passwords. I am not try to enable the use of the Dovecot Master user through Director into the backend servers. a.) username is being sent as masteruser*username b.) request hits the proxy and authenticates, and then is passed to the backend servers and fails auth. - logs from proxy/Director point of view. auth: Info: passwd-file(masteruser,172.31.33.224,master,<z2eYD0Rl6P+sHyHg>): Master user logging in as devteam imap-login: Info: proxy(devteam): Login failed to backend.servers:143 (master masteruser): [AUTHENTICATIONFAILED] Authentication failed.: user=<devteam>, method=PLAIN, rip=172.31.33.224, lip=192.168.71.20, session=<z2eYD0R l6P+sHyHg> - logs from backend server point of view. imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<masterusername>, method=PLAIN, rip=192.168.71.20, lip=192.168.71.99, session=<O8QN8kNlloXAqEcU> Proxy/Director Configs (hopefully this is enough) auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/conf.d/master-user-password master = yes pass = yes } passdb { driver = static args = proxy=y nopassword=y } Please let me know if I can provide any further details.

Selective authentication mechanism
by Brian Topping 16 Feb '18

16 Feb '18

Hi all! I have been using GSSAPI authentication method for all my externally reachable endpoints for some time under the theory that they cannot be hit with a dictionary attack. Unfortunately, this means iOS devices cannot log in since they (oddly) cannot use GSSAPI. I say “oddly” because desktop Mac mail can use GSSAPI just fine and https://samuelyates.wordpress.com/2013/10/11/kerberos-single-sign-on-in-ios… goes through how to set it up for web pages. In any event, what I’m looking to do is use a filter (https://wiki.dovecot.org/ConfigFile#Filters) around the auth_mechanisms such that it will allow plain authentication when the client is on a local network or the VPN. Unfortunately, the fine print on filters says "These filters work for most of the settings, but most importantly auth settings currently only support the protocol filter”. I guess it’s kind of academic, but I thought I’d ask why this is a limitation? If there is not a profound security reason to not support this, is this a good enough use case to consider it? Thanks! Brian

ACLs, shared, public, virtual mailboxes not working
by David Mehler 15 Feb '18

15 Feb '18

Hello, I'm running Dovecot 2.2.3, and am having issues with my public folders, shared folders, and virtual/ALl folders apparently ACLs are on that list as well. I was debugging an unrelated problem with my smtp server and got the following dovecot debug log output. Below is also a doveconf -n output as well as my shared-folder definition file and my global-acls file. What I'm trying to accomplish is: 1. Have a public folder that any user on the system can put messages into and respond to. 2. Have a shared folder in which user1(a)example.com and user1(a)example2.com can exchange messages. 3. For each user on the system give them a Virtual/All folder for *all of their messages. I'd appreciate any help. As an aside if anyone sees an issue with my SSL ciphers list i'd appreciate knowing that as well, in brief I'm trying to get the most secure list, pfs, and not worrying about backware compatibility. If it's not TLS 1.2 I don't touch it. Thanks. Dave.

Segfault on selecting mailbox twice in a row
by John van der Kamp 15 Feb '18

15 Feb '18

Hi, I was doing some testing with new 2.2 changes. I’m using commit 15d5b8a from origin/master-2.2. The setup is using imapc to connect to a different imap server. If I use the following commands, dovecot will crash every time: A login username password B select inbox C select inbox The logfile snippit is at the end of the mail. Let me know if you need more information.

Ok thanks, for the moment : can I just delete the lines in the dovecot-init.service file or what is proposed here?

doveadm with wildcard users?

# 2.2.33.2 (d6601f4ec): If I do doveadm index -u user "*" for a local user, it works fine, but if I do doveadm -u "*(a)sqldomain.tld" "*" or doveadm -u "*(a)localaliasdomain.tld" "*" or doveadm -u "*(a)localdomain.tld" "*" or doveadm -u "user(a)localdomain.tld" "*" it fails, … -u "user(a)sqldomain.tld" Seems to work <https://wiki2.dovecot.org/Tools/Doveadm/Index> -u user/mask Run the command only for the given user. It's also possible to use '*' and '?' wildcards (e.g. -u *(a)example.org)

Problem with CentOS package for 2.3.0 and old dependency in systemd with clean install
by TG Servers 14 Feb '18

14 Feb '18

Hi, you definitely have a problem with the packages out of your own repo for version 2.3.0 and CentOS. And this is only if you do a clean install, meaning there was no lower dovecot version ever running on the system. If you want to 'systemctl start dovecot' it breaks with a dependency error which comes from dovecot-init.service. dovecot-init.service : [Unit] Description=One-time Dovecot init service ConditionPathExists=|!/var/lib/dovecot/ssl-parameters.dat ConditionPathExists=|!/etc/pki/dovecot/certs/dovecot.pem [Service] Type=oneshot RemainAfterExit=no ExecStart=/bin/sh -c '\ if [ ! -f /etc/pki/dovecot/certs/dovecot.pem ]; \ then\ SSLDIR=/etc/pki/dovecot/ OPENSSLCONFIG=/etc/pki/dovecot/dovecot-openssl.cnf /usr/libexec/dovecot/mkcert.sh /dev/null 2>&1;\ fi;\ if [ ! -f /var/lib/dovecot/ssl-parameters.dat ]; \ then\ /usr/libexec/dovecot/ssl-params >/dev/null 2>&1; \ fi' It wants to call /usr/libexec/dovecot/ssl-params if /var/lib/dovecot/ssl-parameters.dat (which is deprecated now as I understood) is not existing. The problem is in 2.3.0 /usr/libexec/dovecot/ssl-params is not existent anymore. This error does not occur if you for instance install 2.2.x from the base repo, start it once, and then update the version from your repo. This is because the ssl-parameters.dat was created with the old version then. But this should not be the expected behaviour I think. It should be possible to do a fresh install of 2.3.0 on a fresh system. Can you please get back to me on that? Thanks, Thomas

In https://wiki2.dovecot.org/Tools/Doveadm/Sync#section_arguments the destination list 5 possible options for the destination but in the page on migration https://wiki2.dovecot.org/Migration/Dsync it seems to use a sixth undocumented "imapc:" option for destination e.g. doveadm -o mail_fsync=never backup -R -u user@domain imapc: "imapc:" is also referenced on https://wiki2.dovecot.org/Migration/Gmail Is https://wiki2.dovecot.org/Tools/Doveadm/Sync#section_arguments missing this option?

deny passdb match messages logged only with auth_verbose=yes
by Marco Giunta 13 Feb '18

13 Feb '18

Hi at all, using deny passwd to restrict IMAP/POP3 access (https://wiki.dovecot.org/Authentication/RestrictAccess) I get deny passdb match messages: Feb 13 16:09:33 server-02 dovecot: auth: passwd-file(USERNAME,10.10.10.46,<9hzaYRllbsCTehgu>): User found from deny passdb only with auth_verbose=yes, sets global or defined in passdb block. But if I set auth_verbose=yes, for every user not present in passwd-file, Dovecot logs: Feb 13 16:09:57 server-02 dovecot: auth: passwd-file(USERNAME,10.10.10.46,<9hzaYRllbsCTehgu>): unknown user I know that if the account does not exist in the first passdb (deny passdb), then the error occur, even if it exists in the other passdb. This is normal, but auth_verbose shouldn't be used only to " Log unsuccessful authentication attempts and the reasons why they failed." ?? Again, I'm not a programmer, but 'auth_request_log_info' function in 'https://github.com/dovecot/core/blob/release-2.2.33/src/auth/auth-request.c' seems to log events only when 'auth_verbose=yes'. Is there another way to get deny passdb match messages, without enable verbose log ?

dovecot: master: Panic: kevent() failed: Invalid argument
by Adrian Gonzalez 13 Feb '18

13 Feb '18

Hello I've been seeing these panics with dovecot 2.2.31 (and older versions) under FreeBSD about once every 2-3 months or so. I know it's been discussed here in the list, but I didn't see a definitive fix. If it's been fixed, please ignore this post (sorry!). I finally managed to observe the bug on a server that has the patch that prints out the kevent() timespec values and got: Nov 29 16:46:27 mail dovecot: master: Panic: kevent(events=74, ts=59.1000000000) failed: Invalid argument Looking through the code, the panic is triggered in io_loop_handler_run_internal(). The timeout values for the kevent() call are obtained by calling io_loop_get_wait_time(), which in turn calls timeout_get_wait_time() (both in ioloop.c). The timeout is computed by subtracting the value returned by gettimeofday() from timeout->next_run, and it looks like in very rare cases the result in tv_r->tv_usec is 1000000uS (1 second). So, it seems that if gettimeofday() returns exactly 0 microseconds, and timeout->next_run has exactly 1000000 microseconds, the kevent() call will fail (1 in 1e12 chance?). I'm not entirely sure where timeout->next_run is computed, but looking at timeout_update_next(), it adjusts the seconds only if the microseconds are greater than 1000000: (ioloop.c, line 235) if (timeout->next_run.tv_usec > 1000000) { timeout->next_run.tv_sec++; timeout->next_run.tv_usec -= 1000000; } It seems like the comparison here should be greater or equal, but I'm not familiar enough with the code to say with absolute certainty. I added more debug error messages to the code in timeout_update_next(), and although I do see next_run->tv_usec at 1000000 several times a day, I haven't seen a panic since early December on any of our servers, so I decided to post this to see if this analysis makes sense.

Setting up sieve with spam learning

Cribbing from the dovecot site I recently added the following lines to my dovecot.conf: managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext imapsieve vnd.dovecot.imapsieve plugin { imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /usr/lib/dovecot/sieve sieve_plugins = sieve_imapsieve sieve_extprograms } protocol imap { mail_plugins = " virtual imap_sieve" } Now, should I see the report-spam or report-ham sieve's logged anywhere? Because I am not seeing them.

"search return (min)" is very inefficient
by Jesus Cea 13 Feb '18

13 Feb '18

RFC 4731: " IMAP4 Extension to SEARCH Command for Controlling What Kind of Information Is Returned" https://tools.ietf.org/html/rfc4731 I do this (telnet session): """ a select proveedores/TUHS * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 8330 EXISTS * 0 RECENT * OK [UNSEEN 6085] First unseen. * OK [UIDVALIDITY 1395814416] UIDs valid * OK [UIDNEXT 8358] Predicted next UID * OK [HIGHESTMODSEQ 3149] Highest a OK [READ-WRITE] Select completed (0.264 + 0.000 + 0.263 secs). a search return (min) since 01-Feb-2018 * ESEARCH (TAG "a") MIN 8156 a OK Search completed (59.451 + 0.000 + 59.450 secs). """ Note that it needs 59 seconds to locate the first message matching the "since" criteria. This is really slow and unusable in practice. Things are worse with bigger mailboxes, of course. Am I missing some performance trick?. I am trying to locate the first message received after a particular date. I don't use the "date" header because it can be falsified and because I care about the receiving date and not the actual sending date. I guess dovecot is scanning every message in the folder (mailbox). Wouldn't those messages be stored in ascending "received" order?. Could that be used for bisection search to locate the right message?. Could that break if I copy/move/edit messages?. Is that the reason for such a awful performance?. Suggestions?.

New mail notification
by Matthew Allen 12 Feb '18

12 Feb '18

Hi, So I'm running dovecot 1.2.17 on Mac OSX using maildir in ~/Mail. After using getmail for a while to download my POP3 email and store it in the right place it started not working so I replaced it with a python script that I wrote. All was good for a while and then I stopped getting new mail notifications in my IMAP client. If I close the connection and restart the new mail shows up as !seen but no amount of re-selecting the folder will show the new mail while the connection is active. There is no untagged responses about new mail while the client is IDLEing. The client is InScribe (http://memecode.com/inscribe.php) but I doubt it's client specific. Seems to be server related. Now the python script in question just puts the .eml file in ~/Mail/tmp and then renames it to the ~/Mail/new folder. Does it need to do something else as well to make the notifications work? There aren't any error messages in the log. Just normal login history. If you can point me in the right direction that'd be appreciated. Regards

Best mail encryption solution for per-user
by tai74＠vfemail.net 11 Feb '18

11 Feb '18

Hai, Do you have advice about Dovecot plugins for mail encryption: https://wiki2.dovecot.org/Plugins/MailCrypt https://0xacab.org/riseuplabs/trees I like NaCL based encryption but the MailCrypt plugin is better because it's maintained by Dovecot developers (is this correct?) Hard to understand MailCrypt docs so may I ask, may I provide per user encryption? I don't like global because I want every user to have different encryption based on their password. But I don't see the useful of per-folder encryption. Docs for TREES are easier to understand it will work on a per-user encryption using the user password to decrypt the needed keys. How about indexing? Does native fast Dovecot indexing must be turned off for one of these or both? Is this a big performance hit? And how to turn off indexing on a per-user basis?

LDAP userdb and dovecot LDA/LMTP - different requirements
by Franta Hanzlík 10 Feb '18

10 Feb '18

Hi, I want to use Dovecot LDA (or rather LMTP) use as local deliver with Postfix MTA. Users are in LDAP DB with structure as: dn: cn=username, ou=rank, o=myorg cn: username objectClass: Person gidNumber: uNNN uidNumber: gNNN userPassword: (somehow hashed, can only bind verification) homeDirectory: /Home/$rank/$username mailActive: 0/1 mail: usera@OneDomain mail: userb@SecDomain (not all users have 2+ addresses] uid: username groupMembership: group DN (can be multiple times for different groups) ... where: - cn = uid = expected IMAP login username (which hasn't @domain part) - user1 (and user2) isn't always same as username Now I not know, how to solve IMO diferent requirements to userdb: - LDA/LMTP need LDAP userdb unit, that can retrieve the name from an email address (ie for "usera@myDomain" returns cn/uid (as dovecot "username"). - IMAP server need LDAP userdb unit, that will have the user login (username) as the input parameter, and which returns information whether or not the user exists. Can be these different requirements solved in one userdb unit? Or is it possible to have one userdb unit for LDA/LMTP, and another one for IMAP and other Dovecot components? I have also encountered entries getting the values from LDAP userdb in the form as: user_attrs = \ =user=%{ldap:uid}, \ @mail=base(%{ldap:mailDN}), \ =uid=%{ldap:uidNumber@mail}, \ =gid=%{ldap:gidNumber@mail}, \ =home=%{ldap:rootPath@mail}/%d/%n or user_attrs = \ =home=%{ldap:homeDirectory}, \ =uid=%{ldap:uidNumber}, =gid=%{ldap:gidNumber}, =quota_rule=*:bytes=%{ldap:quotaBytes}, =namespace/default/separator=%{ldap:mailSeparator} Can anyone explain how these constructions work? And what do mean attribute notations in the form '=attr=' or '@attr=' or 'quota_rule=*:storage=100M' ? Nowhere have I found a sufficiently comprehensible description of these constructions... Help very much appreciated. Thanks, Franta Hanzlik

Hi - Updated from 2.2.27 to 2.3.0 server is webmail (roundcube) Sending worked before after update. Now it receives, but trying to send - this is the bounce in the log Feb 9 01:37:45 {hostname} postfix/pipe[22891]: 931FD2577: to=<{user}(a){hostname}.{tld}>, relay=dovecot, delay=0.01, delays=0/0/0/0, dsn=5.3.0, status=bounced (command line usage error.

08 Feb '18

Hello, I've noticed an annoying problem. Trying to delete a folder that has been deleted on IMAP and is moved to trash has problems being deleted. Thunderbird reports: "Folder contains children" and stops there. Folder at first disappears. But after restarting Thunderbird they are still there and on Dovecot-Mailbox folder on the server the folders are also still present. I'm using Dovecot 2.2.18 + Thunderbird + FS-Layout. I already tried this workaround-mode: > /protocol imap { //imap_client_workarounds = tb-extra-mailbox-sep //}/ best regards Gabriel Kaufmann _____________________________ TYPOWORX ΝΞШ.ΜΞDIΑ Gabriel Kaufmann Siegfriedstraße 38 | 38106 Braunschweig USt.Id Nr.

I also deleted Trash.sdb and Trash.msf in ImapMail-Dir of given Mailbox (after closing Thunderbird of course and restart afterwards). I think the repair-button does more or less the same than deleting msf-files. Trash was rebuilding... but the Folders are still there. I was able to get rid of some other "Junk folders" (that not even where shown in my Thunderbird-Trash inside Trash.sdb folder). But the folders causing current issue are still present after sync! And on server-side (vmail Mailbox on imap-server) these folders are also there! I'm still not able to delete them in Thunderbird. Still getting error Folder contains children, delete them first". Obviously this isn't possible as those sub-folders are not shown in Thunderbird! On server-side of imap (vmail Mailbox) there are in fact sub-folders in those folders. Best regards Gabriel Kaufmann

2.3.1/0.5.1?
by Larry Rosenman 07 Feb '18

Timo & Company, There have been a ton of fixes since 2.3.0. Is there a 2.3.1 of Dovecot and 0.5.1 of pigeonhole on the near horizon? Thanks!

Segmentation fault in "make check" test_istream_multiplex for 2.3.0 on Solaris Sparc

New mail notification
by Matthew Allen 07 Feb '18

07 Feb '18

Hi, So I'm running dovecot 1.2.17 on Mac OSX using maildir in ~/Mail. After using getmail for a while to download my POP3 email and store it in the right place it started not working so I replaced it with a python script that I wrote. All was good for a while and then I stopped getting new mail notifications in my IMAP client. If I close the connection and restart the new mail shows up as !seen but no amount of re-selecting the folder will show the new mail while the connection is active. There is no untagged responses about new mail while the client is IDLEing. The client is InScribe (http://memecode.com/inscribe.php) but I doubt it's client specific. Seems to be server related. Now the python script in question just puts the .eml file in ~/Mail/tmp and then renames it to the ~/Mail/new folder. Does it need to do something else as well to make the notifications work? There aren't any error messages in the log. Just normal login history. If you can point me in the right direction that'd be appreciated. Regards Matthew Allen

Dovecot on GlusterFS via NFS is... strange.
by Frank Wall 06 Feb '18

06 Feb '18

Hi, I've discovered some interesting behaviour when running Dovecot on a GlusterFS volume (3.10) that is mounted via NFS 4.1 (ganesha NFS). First of all, using the usual settings for NFS storage seemed like an obvious choice for my setup (Dovecot 2.2.33.2, CentOS 7.4): mail_nfs_storage = yes mail_nfs_index = yes mail_fsync = always maildir_copy_with_hardlinks = yes mmap_disable = yes lock_method = dotlock (FWIW, I've been using these settings for many years on different NFS storages without any issues. Another instance of Dovecot 2.2.33 on FreeBSD 11.1 with a more traditional NFS storage is rock-solid.) SPOILER: These settings caused terrible issues. For example, when trying to clone a mailbox from an old server to this new Dovecot-on-GlusterFS setup (using imapsync), the following errors would show up frequently: Feb 6 16:44:53 dovecot: IMAP(user(a)example.com): Panic: file maildir-uidlist.c: line 1262 (maildir_uidlist_write_fd): assertion failed: (first_idx == 0) Feb 6 16:44:53 dovecot: IMAP(user(a)example.com): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9f3de) [0x7f7b6b44f3de] -> /usr/lib64/dovecot/libdovecot.so.0(+0x9f4be) [0x7f7b6b44f4be] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f7b6b3e077c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x79605) [0x7f7b6b75b605] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_uidlist_sync_finish+0x1ac) [0x7f7b6b75d61c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_uidlist_sync_deinit+0x98) [0x7f7b6b75da48] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_transaction_save_commit_pre+0x41f) [0x7f7b6b75483f] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xcccd0) [0x7f7b6b7aecd0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0x9d) [0x7f7b6b7cb3cd] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x107) [0x7f7b6b7af217] -> /usr/lib64/dovecot/lib10_quota_plugin.so(+0xe17c) [0x7f7b6a9ca17c] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xda0a) [0x7f7b6abe0a0a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_changes+0x51) [0x7f7b6b72c161] -> dovecot/imap [user(a)example.com 10.0.0.1 APPEND](+0xf255) [0x55ca8238f255] -> dovecot/imap [user(a)example.com 10.0.0.1 APPEND](command_exec+0x5c) [0x55ca8239cf0c] -> dovecot/imap [user(a)example.com 10.0.0.1 APPEND](+0xe771) [0x55ca8238e771] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7f7b6b464cd2] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10f) [0x7f7b6b4663bf] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7f7b6b464d6c] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f7b6b464f28] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f7b6b3eafa3] -> dovecot/imap [user(a)example.com 10.0.0.1 APPEND](main+0x333) [0x55ca8238e2e3] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f7b6b00ec05] -> dovecot/imap [user(a)example.com 10.0.0.1 APPEND](+0xe476) [0x55ca8238e476] Feb 6 16:44:53 dovecot: IMAP(user(a)example.com): Fatal: master: service(imap): child 84782 killed with signal 6 (core dumps disabled) Feb 6 16:44:56 dovecot: IMAP(user(a)example.com): Error: readdir(/data/mail/abc/default/.Foldername 01_ Foo 1234/new) failed: Unknown error 523 Yes, the folder name is "special" in this example. (I'm not sure if this readdir() error is actually related to the other issue.) So, this caused the imap process to die repeatedly and the user got disconnected many many times. In this state the mail services were not really usable. Side note: The NFS share was mounted by using the most conservative moint options I could think of: vers=4.1,rsize=131072,wsize=131072,nosharecache,noac,nordirplus,proto=tcp And if you're wondering: Yes, I'm using Dovecot director for IMAP and LMTP (currently running 3 VMs for Dovecot director and 3 VMs for Dovecot IMAP). Then the fun began... I've decided to change the following settings: mail_nfs_storage = no mail_nfs_index = no Re-created the maildir and restarted the imapsync copy process. Out of sudden the errors are gone! Now Dovecot is performing pretty well on my GlusterFS volume. Does this make any sense to anyone? Ciao - Frank

"make check" test-hash-method bus error (Sparc alignment)
by Rainer Jung 06 Feb '18

06 Feb '18

Hi there, when doing "make check" for a 2.3.0 build on Solaris Sparc I get a bus error due to an alignment issue. It seems the error is only happening during testing, because in the official API it was fixed in https://github.com/dovecot/core/commit/d8361cc8576d9ede93a037f9b96f2a3f9b7e… But the tests use hand written test vectors, that are not correctly aligned: ... hash method md4 (test vectors) ....................................... : ok hash method md5 (test vectors) ....................................... : ok /bin/ksh[2]: 24287 Bus Error(coredump) make[4]: *** [Makefile:2655: check-local] Error 1 gdb output: Program terminated with signal SIGBUS, Bus error. #0 sha1_loop (ctxt=0xffbff724, input=0x83908, len=3) at sha1.c:224 224 ctxt->c.b64[0] += copysiz * 8; (gdb) print &ctxt->c.b64[0] $1 = (uint64_t *) 0xffbff73c So the address of the 8 byte type is not divisible by 8 (Sparc alignment requirement).

Dovecot and /dev/rand
by Michael A. Peters 06 Feb '18

06 Feb '18

There's a (2014 I think) patch in dovecot rpm for Red Hat / Fedora ecosystem that was last update with 2.2.9 (patch last updated for that release) I want to know if the problem it solves still exists in 2.3.x branch. The patch is called "dovecot-2.2.9-nodevrand.patch" and is attached. It allegedly addresses an issue with installation in chroot that does not have /dev/random Red Hat bugzilla 1026790 I am apparently not authorized to see that bug so I don't know much about it, but with many code changes in 2.3.0 from 2.2.x I am wondering if the alleged issue was solved a different way or if the patch should be ported to 2.3.0 when packaged for people who might trigger it. Thanks.

Does Dovecot LDAP auth support LDAP referral
by Xuan Jia 06 Feb '18

06 Feb '18

We using Dovecot with LDAP. From the beginning, we using GC LDAP query with port 3268 for email accounts. For example, user1(a)our-organization.org (in the USA) with "base = dc=our-organization, dc=org" works fine. But refer to this document: https://wiki2.dovecot.org/AuthDatabase/LDAP When we change the LDAP from 3268 to 389 and with TLS, the base should be changed like this: "base = ou=usa, dc=our-organization, dc=org" But if the user (user2) located in United Kingdom (ou=gbr), the user can not login. When we debug with ldapsearch: ldapsearch -ZZ -v -h dc.our-organization.org -p 389 -D 'cn=auth_user,ou=usa,dc=our-organization,dc=org' -W -b 'dc=our-organization, dc=org' '(userPrincipalName=user2(a)our-organization.org)' It can return user2 information with some "numReferences". But in Dovecot, if "base = dc=our-organization, dc=org" it only reported auth error with timeout. Here are the config: # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 9.3 auth_verbose = yes dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} imap_id_send = imapc_user = %u import_environment = TZ listen = * login_log_format_elements = user=u> method=%m rip=%r lip=%l mpid=%e %c mail_shared_explicit_inbox = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve" service managesieve-login { inet_listener sieve { port = 4190 } service_count = 0 } ssl_ca = /etc/ssl/certs/ca.pem ssl_cert = </etc/ssl/gameloft/our-organization.org.crt ssl_key = # hidden, use -P to show it ssl_parameters_regenerate = 1 weeks userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } So my question is: does Dovecot LDAP auth support LDAP referral? If Dovecot relies on OpenLDAP, it should be support. If not, why and what is the walkthrough? Xuan Jia

Re: How to grant user access to his .dovecot.sieve.log?
by Sergey Ivanov 04 Feb '18

04 Feb '18

Hi Gabriel, I'm trying to implement what you suggested using apache mod_userdir with === UserDir /srv/dovecot <DirectoryMatch "^/srv/dovecot/(?<WHICHUSER>[^/]+)"> Require user %{env:MATCH_WHICHUSER} DirectoryIndex .dovecot.sieve.log ... </DirectoryMatch> === I still need to find how to set up right permissions for these logs without too much brute force. It looks like this way I can get what I want, but I really hoped to find some better way: my Roundcube installation is on the load-balanced web farm and there is no and should not be a file access to these logs. I think such a feature as Sieve compiler must have some standard way to say what is wrong to the author of the Sieve script. -- Sergey.

Dual Dovecot setup
by dovecot.dirk＠o.banes.ch 03 Feb '18

03 Feb '18

Hi all, I´m using dovecot successfully since some years. My current setup is postfix and dovecot on one vserver. This works great so far. +--------------------+ eMail in | VSERVER1 | +---------->+ MX 1 (Master) | | POSTFIX MTA | | DOVECOT ALL Folders| +-----^--------------+ | |eMail Backup | | +------+---------+ | VSERVER2 | eMail in | MX 2 (Backup) | Backup | POSTFIX MTA | +---------> | +----------------+ However now I want to change this setup to have on box in my home which holds all eMails and Folders which are not in the Inbox. This is due to disk space and privacy concerns. Even if the home connection is very very stable for the case something fails while on vacation the content of the inbox of every user should always stay on the VSERVER1 as well - until it is moved to one subfolder. +---------------+ +-------------+ eMail in | VSERVER1 | | HOMEBOX | +---------->+ MX 1 (Master) | ?SYNC? | DOVECOT | | POSTFIX MTA +--------------> ALL FOLDERS | | DOVECOT INBOX | | | +-----^---------+ +-------------+ | |eMail Backup | | +------+---------+ | VSERVER2 | eMail in | MX 2 (Backup) | Backup | POSTFIX MTA | +---------> | +----------------+ I read into documentation and also did a fair share of googeling but I could only identify possible solutions which I´m not sure they will work. a) dsync - Can dsync only sync the Inbox ? b) fetchmail - Unsure how an eMail moved from Inbox (Homebox) to another folder would get removed from the inbox of the vserver1 Therefore I hope maybe someone of you has an idea how this can be archived. Thank you best regards Dirk

dovecot-lda won't cause mail to be filtered by sieve
by Volker Wysk 03 Feb '18

03 Feb '18

Hi I'm changing from fetchmail to getmail, in order to fetch my mail from several mail servers and deliver it to my local dovecot server. Fetchmail supports LMTP, getmail doesn't. So I'm making getmail call dovecot-lda for delivering the mail. But now, the incoming mail doesn't get filtered through sieve any longer. However, this command works: sieve-filter -v -u v ~v/.dovecot.sieve INBOX -e -W expunge Any ideas? Greetings V.W.

AuthDatabase CheckPassword broken?
by Mark Foley 02 Feb '18

02 Feb '18

I had been using the CheckPassword authentication interface with dovecot 2.2.15, https://wiki2.dovecot.org/AuthDatabase/CheckPassword, and it was working. After upgrading to 2.2.33.2 CheckPassword no longer works. The referenced wiki page says, Checkpassword Interface Read <username> NUL <password> NUL from fd 3. I've checked the information read from fd 3 with 2.2.33.2 and I get <username> followed by 3 nulls. I'm guessing the 2nd null is supposed to be the password. Why is this no longer working? How can I fix it? THX --Mark

lda: Warning: Failed to parse return-path header: Invalid character in localpart
by Christian Authmann 01 Feb '18

01 Feb '18

Hello, Sometimes, when delivering mails, this warning appears in my syslog: > lda(...): Warning: Failed to parse return-path header: Invalid character in localpart dovecot-lda still exits with 0 and the mail is inserted into my inbox. Looking at the mails in question, I determined that the error is caused by a multiline Return-Path header. Here's a testcase: --- snip --- Return-Path: <nowhere(a)example.com> From: "Nowhere" <nowhere(a)example.com> To: redacted(a)example.com Subject: Testcase for lda warnings Date: Wed, 31 Jan 2018 12:00:00 +0000 This is a message body. --- snap --- Copy into a file, with \r\n line endings, then run something like this: > cat testcase.txt | /usr/lib/dovecot/dovecot-lda -e -d '<username>' with a username recognized by your running dovecot installation. The header is 'Return-Path:', \r\n, two spaces, '<...>', \r\n According to rfc2822 folding rules, that should be valid - the Return-Path header allows CFWS at that location. The error message originates in lib-lda/mail-deliver.c in mail_deliver_get_return_address(), while the invalid character message seems to originate from one of several places in lib-lda/mail-deliver.c Ciao, Christian Authmann

Error in virtual mailbox dovecot 2.3-devel maybe in mailcount
by Jakobus Schürz 01 Feb '18

01 Feb '18

Hi there! I splitted my Mailarchiv to an extra namespace. Because i have some Problems with the Archiv. I can open all Folders from Mailarchiv with dovecot. But i want to have a "all archives" Mailbox to search in all messages in only one virtual mailbox. Trying to open this virtual folder from thunderbird, I get in a big archiv this error in logs from dovecot: Jän 12 10:54:41 aldebaran dovecot[839]: imap(jakob)<11302><9ILYQJFipPlcPAkS>: Error: virtual index /var/mail/virtual/ARCHIV: Broken mailbox_count header Jän 12 10:54:41 aldebaran dovecot[839]: imap(jakob)<11302><9ILYQJFipPlcPAkS>: Error: virtual index /var/mail/virtual/ARCHIV: Broken mailbox_count header Jän 12 10:54:41 aldebaran dovecot[839]: imap(jakob)<11302><9ILYQJFipPlcPAkS>: Panic: Leaked view for index /var/lib/dovecot/db/indexes/archiv/jakob/Archiv/2016/Mailinglisten/stvkr-a/dovecot.index: Opened in index-storage.c:336 Jän 12 10:54:41 aldebaran dovecot[839]: imap(jakob)<11302><9ILYQJFipPlcPAkS>: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0xc6021) [0x7f391bf02021] -> /usr/local/lib/dovecot/libdovecot.so.0(+0xc60ed) [0x7f391bf020ed] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f391be74481] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0xf3942) [0x7f391c2a1942] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_mailbox_close+0x72) [0x7f391c278ec2] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_close+0x1a) [0x7f391c1f8c0a] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(+0xa7e0) [0x7f39174637e0] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(virtual_backend_box_open+0x2b) [0x7f391746397b] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(virtual_storage_sync_init+0x1026) [0x7f3917466926] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x4d) [0x7f391c1fb05d] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_sync+0x37) [0x7f391c1fb117] -> dovecot/imap [jakob 92.60.9.18 select](cmd_select_full+0x171) [0x55759e0911a1] -> dovecot/imap [jakob 92.60.9.18 select](command_exec+0x64) [0x55759e098ca4] -> dovecot/imap [jakob 92.60.9.18 select](+0x1b0b2) [0x55759e0970b2] -> dovecot/imap [jakob 92.60.9.18 select](+0x1b13c) [0x55759e09713c] -> dovecot/imap [jakob 92.60.9.18 select](client_handle_input+0x1a5) [0x55759e097565] -> dovecot/imap [jakob 92.60.9.18 select](client_input+0x82) [0x55759e097be2] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7f391bf19c09] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x109) [0x7f391bf1b4a9] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x52) [0x7f391bf19d12] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f391bf19f28] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f391be971e3] -> dovecot/imap [jakob 92.60.9.18 select](main+0x328) [0x55759e089768] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf1) [0x7f391babd2b1] -> dovecot/imap [jakob 92.60.9.18 select](_start+0x2a) [0x55759e08994a] Jän 12 10:54:41 aldebaran dovecot[839]: imap(jakob)<11302><9ILYQJFipPlcPAkS>: Fatal: master: service(imap): child 11302 killed with signal 6 (core not dumped) and if i search the virtual mailbox with doveadm i get almost the same error.

Why does dovecot reject password when authorizing by a certificate?
by yuryb 01 Feb '18

01 Feb '18

We have FreeBSD-server with dovecot installed on it as IMAP-server. My user and password database is a text file with plaintext passwords. Clients connect to imap-server via TLS protocol and plaintext password. All works fine. But I want to configure ability to authorize with a client certificates. I have generated a client certificate and imported it to email-client. Also I have configured dovecot to verify client certificates. But email-client cannot authorize: Password mismatch. Why dovecot reject my password in this case? Please help!

send specific NDR message for users in certain OU
by lists 30 Jan '18

30 Jan '18

Hi, The question can perhaps be made more generic like this: Can dovecot generate a *specific* NDR (or an autoreply) for accounts that meet a specific criterium, such as: - user account was found under OU=to-delete,CN=company... contrary to the regular location CN=Users,CN=company... We would like to move to-be-deleted users to this container, before actually deleting them. That gives us an easy way to revert, if the deletion turns out to be erroneous. We could do that with via a sieve config for those accounts, but if dovecot could send a "delivery failure"-type specific for those accounts (with instructions who to contact to revert the situation) it would be very easy: only move the user to the specific OU, and have the system do the rest. Can this be done? (dovecot 2.1.17 on wheezy, yes we know we should upgrade, and we also will, but it runs rock solid...) MJ

2 panics, 1 segmentation fault in dovecot 2.3.0 (fts)
by Infoomatic 30 Jan '18

30 Jan '18

Hi, While testing our migration to dovecot 2.3.0, we encountered 2 panics, 1 segmentation fault while we wanted to rebuild the solr indizes. Problem [1] was encountered while rebuilding the indizes, and now I don't know how many mails/documents are indexed or where it got stuck. [2] and [3] encountered while just playing around, since I did not know of "tokenize" and did not find a lot of information about it. This is a ubuntu 16.04 machine, dovecot 2.3.0 compiled from source ( + the patch for the recent zlib problem). "doveadm index" runs on a ~ 4GB mdbox-zipped-mailbox for about 3-4 minutes before aborting with the message above, beforehand I did a "/opt/dovecot/bin/doveadm fts rescan -A". When I repeat "doveadm index" it aborts after about 4 seconds, after a "/opt/dovecot/bin/doveadm fts rescan -A" it runs again for 3-4 minutes. Apache tika logs, but those are probably not related to the problem, however, the devs might want investigate the last line: WARN Parse exception Expected ';', got "," determining content disposition javax.mail.internet.ParseException: Expected ';', got "," and org.apache.tika.exception.ZeroByteFileException: InputStream must have > 0 bytes I would be happy if you could have a look at this, please, and of course just tell me what further information you need.

problem with lda
by Infoomatic 27 Jan '18

27 Jan '18

Hello, I am currently testing the upgrade from our dovecot v2.2.23 to 2.3.0. I have a strange problem with lda. We use bounce mails for internal users if they try to send virus/spammails. The exact same config works with 2.2.23, but not with 2.3.0. The relevant postfix/master.cf part: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/opt/dovecot/libexec/dovecot/deliver -d ${recipient} -f ${sender} On the same machine, with 2.2.23 I get a bounce mail when trying to send a virus, with the subject "VIRUS in message apparently from you (Eicar-Test-Signature)", to both the users inbox as well as to the mailbox of virusalert(a)ourdomain.internal With 2.3.0, in the logs I get an error: relay=dovecot, delay=0.01, delays=0/0/0/0, dsn=5.3.0, status=bounced (command line usage error. Command output: lda: Fatal: Invalid -f parameter: Missing domain and the alert message is only sent to virusalert(a)ourdomain.internal, but not to the user who tried to send the mail. The relevant part of our dovecot.conf: protocol lda { mail_plugins = " quota zlib sieve acl mail_log notify" postmaster_address = postmaster(a)ourdomain.internal } Does anyone know how to solve this problem? Or is there a workaround via postfix/amavis/spamassassin? Any hints are highly appreciated, thanks! Regards, infoomatic

Send full X.509 client certificate to custom authentication policy server
by Jaime Hablutzel Egoavil 26 Jan '18

26 Jan '18

I'm working with Dovecot 2.3 and I'm wondering if I could send the full X.509 client certificate to my custom authentication policy server. I'm actually aware that I can send the client certificate validity status with something like: auth_policy_request_attributes = ... cert=%{cert} But I want the full X.509 certificate to be able to decide over the basis of certificate extensions, e.g. Certificate Policies extension. Is it currently possible?, what about Lua based authentication?, does Lua currently receive the full client certificate?. -- Jaime Hablutzel - RPC 994690880

Quota plugin creates IMAP folder
by Thorsten Hater 25 Jan '18

25 Jan '18

Hi everyone, I have noticed recently that Dovecot creates lock directories under users' Maildirs which look like IMAP folders. This is bad since users will see IMAP folders that are not supposed to be there. In my logs I see dovecot: imap(...): Error: file_create_locked(/.../Maildir/.vsize.lock) failed: Is a directory The directory in question # ls /.../Maildir/.vsize.lock/ cur/ dovecot.index.log dovecot-uidlist maildirfolder new/ tmp/ so Dovecot seems to think this to be an IMAP folder. I am using Dovecot 2.2.27 under Debian, built from source, the lock_method is set to fnctl, and the quota plugin uses the maildir method. Can somebody advice me on how to fix this? Best regards, Thorsten

Single mailbox optimizations
by Alex Shishkin 25 Jan '18

25 Jan '18

Hello, I have unconventional load profile for my email server and I would like to ask if someone can suggest optimizations in my case. I have only one mailbox on the server for collecting emails from variety of external mail servers. I use Postfix for collecting emails and Dovecot to provide IMAP for downloading emails from this mailbox. Currently Postfix configured to use LMTP for transferring emails to Dovecot. Dovecot mail storage format is mdbox. Everything was in order (no incoming and active queues in Postfix) when daily incoming email count was up to 1 million emails. But now I have to process up to 2 million incoming emails and I faced bottleneck of 10 emails per second for saving emails from Postfix active queue to mdbox using LMTP. Currently Postfix receives about 20 emails per second, incoming and active queues in Postfix are growing and I have to find the way to speed up transferring process from Postfix to mdbox. This setup is running on the virtual machine with 8 CPU and 8 GB RAM. CPU loaded only by dovecot/lmtp process but not more than 20% per core. I/O wait is 2-3%. Disk load is about 200 wMB/sec and 300 rKB/sec (and this sounds quite a bit for our storage capacity) . Postfix has destination concurrency limit 20 for default and virtual transport (I’m using virtual transport due to virtual domains configuration). Strace showed up that dovecot/lmtp processes have some delays only on waiting for write lock on truncation log file dovecot.index.log. I have temporary moved all index files including truncation log to tmpfs, but this did not help. The only thing that helped me to increase speed up to 20 emails per second is removing almost all emails from the mailbox (with empty Inbox I got even 30 emails per second). But I have to keep all incoming emails in the mailbox at least for one week so this way is unacceptable. So I would like to ask for suggestions, because I can’t find the root cause of this bottleneck.

No reason to tell me about security, I just need chmod for my tests. Where to change it ?

Questions about SPECIAL-USE IMAP extension
by Joseph Tam 24 Jan '18

24 Jan '18

I'd like to configure my dovecot service to use the IMAP SPECIAL-USE extension, but have a few questions for those who have used them, or are knowledgable about its use. Using this configuration as an example, namespace { ... mailbox xxx { special_use = \Sent } } Q1) Am I correct that mail client that don't understand SPECIAL-USE extentions will behave the same way with repect to outgoing mailbox storage? Q2) Will SPECIAL-USE enabled mail clients switch the mailbox used for outgoing mail from whatever it was using (e.g. "Sent Mail") to the (new) special-use mailbox "xxx"? Q3) Will SPECIAL-USE enabled mail clients connecting for the first time use "xxx" for outgoing mail, auto-creating it if necessary? Or will "xxx" be used only if the user does not manually configure a mailbox for this purpose? Q4) If I have an additional configuration mailbox yyy { special_use = \Sent } how does it affect Q2, Q3? Thanks to any who can provide clarity on this. Joseph Tam <jtam.home(a)gmail.com>
