changed behavior for dovecot-lda in 2.3.x
by Martin Waschbüsch 08 Apr '18

08 Apr '18

Hi all, Hey all, I upgraded to dovecot 2.3.1 (from 2.2.34) and noticed that the behavior for dovecot-lda changed. Apparently it no longer accepts -f "" or -f "<>? With 2.2.34, both were accepted now I get: root@mail:~# /usr/local/libexec/dovecot/dovecot-lda -f "<>" lda(root): Fatal: Invalid -f parameter: Null path not allowed or root@mail:~# /usr/local/libexec/dovecot/dovecot-lda -f "" lda(root): Fatal: Invalid -f parameter: Path is empty string I guess this must be a bug? I mean, envelope sender *must* be empty for bounces. Thanks, Martin

I’m in the process of upgrading an old server from Fedora 21 to something more modern. Now, Dovecot won’t let any client login to get their email.

sharing a folder with all users in a domain
by David Mehler 07 Apr '18

07 Apr '18

Hello, I'm wanting to make a shared folder that anyone in a domain can get to, but not anyone in any other domain. Here's my dovecot shared namespace: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h:INDEX=~/shared/%%u subscriptions = no list = yes } The dovecot-dict-sql.conf.ext file has: map { pattern = shared/shared-boxes/user/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = anyone_shares value_field = dummy fields { from_user = $from } } and in my global acl file I have: shared/office@ user(a)domain.com lrwstipekxa shared/office@ user2(a)domain.com lrwstipekxa Thanks. Dave.

Dsync from multiple IMAPs -- personal/local dovecot setup
by Kim ALLAMANDOLA 06 Apr '18

06 Apr '18

Hello list, new aspiring user here, if I'm not in the wright place sorry, I do not fund any other option for now... As from subject I'm looking for a *personal* *standalone* dovecot setup, especially I'm looking for a DSync from multiple IMAP accounts to a local maildir (to being compatible with notmuch). My actual mail setup is: OfflineIMAP that sync different mailboxes in a personal taxonomy ~/mail/$mailboxName/... and notmuch-emacs + various scripts as MUA. Local postfix just to avoid emacs freeze during send, muchsync to support It does work but is slow, buggy and sometime complicated to kept up to date (I have many homegrow spaghetti-code scripts and snippets in zsh, elisp, python etc stratified in years). My dream is switch to a local Dovecot that DSync from multiple IMAPs instead of OfflineIMAP, with sieve filters instead of homegrow scripts that wrap notmuch search --output=files | xargs ... For the MUA part I'd like to stick with notmuch. So my questions are: is possible to dsync from multiple IMAPS to a maildir? if yes does dovecot accept physical messages moves if I refile (archive etc) them via notmuch? Thanks! -- Kim ALLAMANDOLA

Re: 2.3.1 Replication is throwing scary errors

I am following git master-2.3 . Here's a last known reasonably good point in the tree where things worked quite well: EGIT_REPO_URI="https://github.com/dovecot/core.git" EGIT_BRANCH="master-2.3" EGIT_COMMIT="d9a1a7cbec19f4c6a47add47688351f8c3a0e372" So something after that (which could have gone into 2.3.1) has caused this. There is also a second issue of a long standing race with replication occurring somewhere whereby if a mail comes in, is written to disk, is replicated and then deleted in short succession, it will reappear again to the MUA. I suspect the mail is being replicated back from the remote. A few people have reported it over the years but it's not reliable or consistent, so it has never been fixed. And lastly there has been an ongoing but seemingly minor issue relating to locking timing out after 30s particularly on the remote host that is being replicated to. I rarely see the problem on my local disk where almost all of the mail comes in, it's almost always occurring on the replicate/remote system. For me it seems very unlikely that on an unloaded/idle VPS there are legitimate problems obtaining a lock in under 30s. This is with the default locking configuration. This problem started happening a lot more after the breakage in (1) above. These replication issues are similar, and could possibly be related. My system is Gentoo Linux keeping up with the latest kernels, and on an EXT4 FS. I am using TCPS based replication. My remote replicate is also on Gentoo Linux with EXT4 but on a Linode VPS (around 250ms latency away). I know in a later post you've said that you don't think it has anything to do with dovecot-2.3.1, so I'd be interested to know what really is the cause in that case. Reuben

Compatibility of Submission in 2.3.1
by Paul Hecker 06 Apr '18

06 Apr '18

Hi, Dovecot 2.3.1 (8e2f634). When using submission one client of mine can not send messages. Directly sending through exim works. Seems that dovecot is too picky or follow the RFC too precise here to be compatible. Here is the debug log (note the space between “From:" and "<user2(a)host.com>”): Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Received new command: MAIL From: <user(a)host.com> Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Submitted Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL: Ready to reply Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Trigger output Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Timeout stop Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Sending replies Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Sent: 501 5.5.4 Invalid FROM: Missing '<' at beginning of path Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL: Destroy Apr 6 12:02:08 mail dovecot: submission(user(a)host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Destroy Is there a chance that you will incorporate a fix (be more compatible but less stringent)?

dovecot welcome scripts for multiple domains
by David Mehler 06 Apr '18

06 Apr '18

Hello, I've got dovecot 2.3 going, and it uses welcome scripts successfully. My question is does anyone have a script that is multi-domain capable? Currently mine sends it's welcome message from say postmaster(a)domain1.com, well I've got five domains, can I set this script up so that it's smart about them? If user(a)domain3.com logs in it would send a message from postmaster(a)domain3.com? If anyone has any welcome scripts i'm curious to take a look. Thanks. Dave.

issue with sieve forwarding after upgrade to 0.5.1
by Christos Chatzaras 05 Apr '18

05 Apr '18

Finally I found a workaround to not depend on sendmail to forward messages using sieve: In postfix main.cf I have: authorized_submit_users = root, filter (I want only root and filter to use sendmail and block other users to send e-mails from system accounts. Only allow users to send e-mails from virtual accounts and after smtp authentication. Username filter is used for bogofilter and needs access to sendmail) And in dovecot.conf: submission_host = 138.201.248.xxx The same workaround maybe works for NoNewPrivileges too as the authorized_submit_users setting in postfix has similar result.

I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it. We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24. But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on. Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving. Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this. Regards

issue with sieve forwarding after upgrade to 0.5.1
by Christos Chatzaras 04 Apr '18

04 Apr '18

Hello, After I upgrade dovecot 2.2.35 to 2.3.1 and pigeonhole 0.4.23 to 0.5.1 when I use sieve to forward a message to other address using "redirect :copy" I get this: (host server1.myserver.com <http://server1.myserver.com/>[private/dovecot-lmtp] said: 451 4.2.0 <chris(a)mydomain.com <mailto:chris@mydomain.com>> Execution of Sieve filters was aborted due to temporary failure (in reply to end of DATA command)) And in sieve log I see: failed to redirect message to <chris(a)mydomain.com <mailto:chris@mydomain.com>>: Sendmail program returned error (temporary failure). Any idea what is wrong? Kind regards, Christos Chatzaras

Saving Drafts with Roundcube marks old Mails in INBOX as unread.
by sk＠tyrion.de 04 Apr '18

04 Apr '18

Hello List, I have a problem with the client Roundcube. Whenever I save a draft to the Folder INBOX.Drafts a old mail in my INBOX will be marked as unread. Here are the IMAP Logs from Roundcube and Dovecot debug logs. I have no idea why it happens. The IMAP protocol looks normal to me but as you can see in the second to last line in the Dovecot log Dovecot is changing the flag of an old E-Mail in INBOX that has the same UID as the Mail that was just created in INBOX.Drafts.

Use of separate storage for mail delivery
by SAAHIL IFTEKHAR 04 Apr '18

04 Apr '18

Hi I am facing one issue which is mostly about concepts. I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it. We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24. But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on. Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving. Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this. Regards

2.3.1 Replication is throwing scary errors
by Michael Grimm 03 Apr '18

03 Apr '18

Hi [This is Dovecot 2.3.1 at FreeBSD STABLE-11.1 running in two jails at distinct servers.] I did upgrade from 2.2.35 to 2.3.1 today, and I do become pounded by error messages at server1 (and vice versa at server2) as follows: | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail_change, last recv=mail_change (EOL)) | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=changes recv=mail_requests) […] | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail, last recv=mail (EOL)) | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=mails recv=recv_last_common) I cannot see in my personal account any missing replications, *but* I haven't tested this thoroughly enough. I do have customers being serviced at these productive servers, *thus* I'm back to 2.2.35 until I do understand or have learned what is going on. Any ideas/feedback? FYI: I haven't seen such errors before. Replication has been working for years now, without any glitches at all. Regards, Michael

dovecot auth error: Illegal seek

Hi, I recently configured dovecot to manage auth for both local and virtual user. When i login as a virtual user (claudio.panetta) I get the following message: dovecot: auth: Error: passwd(claudio.panetta,160.97.62.1,<WLjlnZ9oRACgYT4B>): getpwnam() failed: Illegal seek but login is ok and sending/receiving email is ok, how can, if possible, I suppress this error message?

multi-site SSL certificates
by Jeff Abrahamson 03 Apr '18

03 Apr '18

I'm handling mail for several domains, let's call them a.com, b.com, and c.com. I have certificates for each of these domains individually via certbot (letsencrypt) and nginx is happy with all of that. Since I initially configured the site to handle mail only for a.com, my /etc/postfix/main.cf file currently has these two lines: smtpd_tls_cert_file = /etc/letsencrypt/live/mail.a.com/fullchain.pem smtpd_tls_key_file = /etc/letsencrypt/live/mail.a.com/privkey.pem But I see that mail test tools are reporting that MX for b.com and c.com are misconfigured due to an SSL name mismatch. Indeed, this is true! So I believe I should generate a multi-site SSL cert. I try this: sudo certbot certonly --cert-name postfix --webroot \ --webroot-path /var/www/a-com -d www.a.com -d a.com -d mail.a.com \ --webroot-path /var/www/b-com -d www.b.com -d b.com \ --webroot-path /var/www/c-com -d www.c.com -d c.com And that fails with a bunch of errors like this: Domain: www.a.com Type: unauthorized Detail: Invalid response from http://www.a.com/.well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ…: "<html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>" I see that the file .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg is being created (and one other file, too) but that nginx reports that the _directory_ .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg doesn't exist. Multi-site + letsencrypt + postfix is a subject that has recently changed quite a bit, so I'm suspecting my web reading is merely leading me astray. It is also entirely possible I've misunderstood things about SSL certificates. Any pointers how to generate (or point to) the certificates that I need to make those who contact my postfix instance happy with their SSL conversation? Thanks!

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 27 Mar '18

27 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 other compilers, such as GCC, might generate a warning about the "return" statement, but Solaris Studio compiler is being more strict about it... 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

Hello, I'm running a virtual mail hosting system with MySQL as a backend for dovecot to do it's authentication against. I am getting intermediant failures when users attempt mail-related tasks such as checking their inbox or setting up an alias. The error is to many connections. Any ideas? Thanks. Dave.
