A few new Pigeonhole features
by Stephan Bosch 14 Apr '16

14 Apr '16

Hi, A few new Pigeonhole features that enthusiasts can experiment with: - Recently, I implemented support for the "imapsieve" extension in Sieve and its IMAP counterpart (https://tools.ietf.org/html/rfc6785) This is now in the Pigeonhole master branch. This allows running Sieve scripts at IMAP activity, rather than at delivery. There are also facilities for the familiar sieve_before/sieve_after administrator scripts. The documentation is currently only in the sources and not on the wiki: https://raw.githubusercontent.com/dovecot/pigeonhole/master/doc/plugins/ima… - Yesterday, I implemented online trace debugging for Sieve scripts: i.e., directly during delivery rather than only using the sieve-test tool. This is also supported for the IMAPSIEVE feature discussed above. This is documented in the INSTALL file: https://github.com/dovecot/pigeonhole/blob/master/INSTALL#L522 In other news, I started a specification for a new Sieve feature that allows using the IMAP SPECIAL-USE attributes from Sieve scripts: https://tools.ietf.org/html/draft-bosch-sieve-special-use-00 There is no implementation yet. Any comments, suggestions or bug reports are welcome. Regards, Stephan.

Dovecot and Windows Live Mail 2012?
by David Mehler 14 Apr '16

14 Apr '16

Hello, I hope someone has this working, because I'm pulling my hair out at this one. I'm using well for this it's a win7 x64 machine running Windows Essentials 2012 and using the Windows Live mail component. I am trying to connect to my Dovecot server running 2.23 I believe. I keep getting the error "the imap command could not be sent to the server because of a non-network error" googling showed many with this, but no fix. In this account I'm trying to access port 143 which uses starttls. In Mail I've got the boxes for require a secure connection and authentication checked. I should note of course and with no surprise that Mail works oh just fine with the Hotmail account I've also got configured, it's only with the downloading of folders and sending of email to the dovecot server that mail has the issue. Please let me know if I can provide any additional information. Help appreciated. Thanks. Dave.

Best way to only replicate specific users
by Max 14 Apr '16

14 Apr '16

Hi, I was wondering about the best way to achieve this. Currently, the users I don't want replicated do not exist on the target system. The source tries to sync them but runs into an error. Technically, that works for me, but it doesn't seem like the right way to do it and clutters the log. Kind Regards, Max

antispam plugin, pipe backend, how to make it work?
by Johannes Rohr 13 Apr '16

13 Apr '16

Hi, my setup is a dovecot 2.0.19 IMAP server on Ubuntu Precise with the antispam plugin in version 2.0+20120225-2 and spamassassin at version 3.2.2 I have been trying and failed to get the pipe backend of the antispam plugin to work. Spamassin by itself works, a manual call of sa-learn works fine. Bayes data is stored in a mysql DB. I have the following configuration in /etc/dovecot/conf.d/90-plugin.conf plugin { #setting_name = value sieve=~/.dovecot.sieve sieve_dir=~/sieve antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_pipe_program = /usr/local/bin/sa-learn-pipe.sh antispam_pipe_program_args = --username=%u # % expansion done by dovecot antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_spam = SPAM;Junk antispam_backend = pipe antispam_verbose_debug = 1 antispam_debug_target = syslog antispam_pipe_tmpdir = /tmp } I have tried the following wrapper script: #!/bin/bash # set -x LOGFILE=/tmp/sa-learn-pipe.log echo "$$-start ($*)" >> $LOGFILE #echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt /usr/bin/sa-learn $* -D /tmp/sendmail-msg-$$.txt >> $LOGFILE 2>&1 && \ rm -f /tmp/sendmail-msg-$$.txt echo "$$-end" >> $LOGFILE exit 0 It somehow isn't working. I can call the wrapper script manually e.g. sudo -u vmail /usr/local/bin/sa-learn-pipe.sh --username=some(a)mail.user --ham \ < someham But it doesn't work from dovecot. It seems the script is called. but no new patterns show up in the bayes DB. Unfortunately, the plugin seems to be documented poorly. How does it call the programme it pipes to? Is it something like $programme --par1 --par2 < message ? Why can't / shouldn't I call sa-learn directly? All the instructions I found on the in internet contained a wrapper script, but none bothered to explain why you would actually need it. I would be very grateful, if someone could enlighten me on that... Cheers, Johannes

speedup doveadm
by Chris 13 Apr '16

13 Apr '16

All, I've to set ACLs in public namespace for more than 5000 folders. That takes some hours. I'm calling doveadm by a perl script. Is there any way to speedup doveadm? Is it possible to set ACLs for multiple folders or users in a single call? - Chris

Problem setting owner
by Luca Bertoncello 13 Apr '16

13 Apr '16

Hi list! I have a Dovecot 2.2.9 installed from Ubuntu-Repository. It uses LDAP to authenticate against an Active Directory controller. The authentication works, but it tries always to use the UID of the user for the mailbox... I already added: mail_uid = 1005 mail_gid = 8 in 10-mail.conf and: user_attrs = \ =user=exim, \ =uid=1005, \ =gid=8, \ =quota_rule=*:bytes=%{ldap:quotaBytes}, \ =home=/home/mailboxes/%{ldap:sAMAccountName}/Maildir, \ =mail=maildir:/home/mailboxes/%{ldap:sAMAccountName}/Maildir in the dovecot-ldap.conf.ext, but it seems to ignore them... Could someone help me? Thanks Luca Bertoncello (lucabert(a)lucabert.de)

fts-lucene with virtual folders
by Dmitry Nezhevenko 13 Apr '16

13 Apr '16

Hi, It looks like I've found something strange. It looks like dovecot updates fts-lucene index every time I'm opening virtual folder that contains FTS query: indexer-worker(dion): Warning: fts-lucene: Settings have changed, rebuilding index for mailbox dovecot-virtual is pretty simple: archive/INBOX BODY "test" first of all, I'm trying to perform FTS in archive/INBOX itself, then I'm trying to open virtual folder. both default namespace and 'archive' are private namespaces with mdbox storage. plugin { fts = lucene fts_lucene = whitespace_chars=@. fts_autoindex = no } Any suggestions? -- WBR, Dmitry

Hi, I´m using dovecot on debian jessie from the xi-rename-it repo (deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main). After upgrading to 2.2.23 I´ve got the following error for example if I delete a message: *Apr 13 15:14:10 mail dovecot: dict(18884): Error: Couldn't load plugin /usr/lib/dovecot/modules/dict/libdict_ldap.so: dlopen() failed: /usr/lib/dovecot/modules/dict/libdict_ldap.so: undefined symbol: ldap_search_start * But I can´t find any ldap settings in my config (doveconf -a). Are any changes that I overlook? Thanks, Michael

v2.3 development tree forked in git
by Timo Sirainen 13 Apr '16

13 Apr '16

The git master branch starts tracking Dovecot v2.3 development from now on. There are soon going to be several API changes there that might break plugins. If you wish to keep tracking latest v2.2.x development instead, switch to master-2.2 branch. The nightly releases at http://dovecot.org/nightly/ will also track v2.3 tree.

Warning: Global setting won't change the setting inside an earlier filter
by Oliver Riesen-Mallmann 13 Apr '16

Hi, I'm using the Dovecot Prebuilt Binary: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main I configured multiple SSL certificates with client TLS SNI (see http://wiki2.dovecot.org/SSL/DovecotConfiguration) Since my last update I get some warnings: doveconf: Warning: /etc/dovecot/conf.d/10-ssl.conf line 12: Global setting ssl_cert won't change the setting inside an earlier filter at /etc/dovecot/conf.d/10-ssl-langzeittest.de.conf line 4 doveconf: Warning: /etc/dovecot/conf.d/10-ssl.conf line 13: Global setting ssl_key won't change the setting inside an earlier filter at /etc/dovecot/conf.d/10-ssl-langzeittest.de.conf line 5 doveconf: Warning: /etc/dovecot/conf.d/10-ssl.conf line 12: Global setting ssl_cert won't change the setting inside an earlier filter at /etc/dovecot/conf.d/10-ssl-langzeittest.de.conf line 4 doveconf: Warning: /etc/dovecot/conf.d/10-ssl.conf line 13: Global setting ssl_key won't change the setting inside an earlier filter at /etc/dovecot/conf.d/10-ssl-langzeittest.de.conf line 5 The reason is this commit: doveconf: Log a warning if a global setting is updated after it was a… …lready set inside a filter https://github.com/dovecot/core/commit/87404eae4581d7ef834f490507503e59a500… My configuration is (shorted): # dovecot -n # 2.2.devel (87404ea): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (215349a) # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.10 [...] ssl_cert = </etc/letsencrypt/live/v083.violet.fastwebserver.de/fullchain.pem [...] ssl_key = </etc/letsencrypt/live/v083.violet.fastwebserver.de/privkey.pem [...] local_name imap.langzeittest.de { ssl_cert = </etc/letsencrypt/live/fahrerlager.langzeittest.de/fullchain.pem ssl_key = </etc/letsencrypt/live/fahrerlager.langzeittest.de/privkey.pem } local_name mail.langzeittest.de { ssl_cert = </etc/letsencrypt/live/fahrerlager.langzeittest.de/fullchain.pem ssl_key = </etc/letsencrypt/live/fahrerlager.langzeittest.de/privkey.pem } I understand, that the warning is correct.

Different usernames for different login method
by Luca Bertoncello 13 Apr '16

13 Apr '16

Hi again! With Dovecot 2.2.9 authenticating against the Active Directory I have following problem: - if I login using LOGIN, PLAIN or CRAM, the username is REALM\login (in my case: CCH\lucabert) - if I login using GSSAPI, the username is just login (in my case: lucabert) this makes the access to the mailbox very difficult, since I don't what can I write in mail_location... If I login with LOGIN, I can write: maildir:/home/mailboxes/%4.u/Maildir but of course it does not work if I login using GSSAPI... The mailboxes have just the login (in my case: lucabert). Can someone explain me why %u is different and how can I solve my problem? Thanks a lot Luca Bertoncello (lucabert(a)lucabert.de)

Slow reading of large dovecot-uidlist files
by Bostjan Skufca 13 Apr '16

13 Apr '16

Hi there, (context: I was optimizing Roundcube mailbox list server response, and in that 300-400ms response time, around 170ms is spent on single fgets() call which is waiting IMAP repsonse to "SELECT MyMailbox" command) I straced dovecot and of the whole request/response process, around 30ms is spent for everything else, and overwhelming majority of time (150-170ms) is spent for reading dovecot-uidlist file for given mailbox. I skimmed over src/lib-storage/index/maildir/maildir-uidlist.c and src/src/lib/istream.c, but I am out of ideas on how to optimize mentioned file reading elegantly to make it faster. Is there any way to cache parsed content of uidlist file(s) or some other obvious quicktrick I am missing to speed this process up? Does anyone have any other ideas, how to speed this up? b.

Dsync Header Hashing
by Richard Laager 13 Apr '16

13 Apr '16

Is there any way to disable the header hashing in dsync? I'm doing a one-time migration to Dovecot using imapc. The FETCHes for Date & Message-ID take a non-trivial amount of time and it's not clear to me if they have a function for a one-time migration. -- Richard

Fwd: Plus addressing on Sentora using Postfix

I am running Ubuntu 14.04.4 LTS “Trusty” and "postconf -d | grep mail_version” gives me “mail_version = 2.11.0”, with Dovecot 2.2.9 I have installed Sentora (http://sentora.org) which sets most of the configuration up for Postfix up, I have made some changes to allow me to use certificates for IMAP and SMTP SSL (https://skippy.org.uk/lets-encrypt-postfix-and-dovecot/) My Postfix main config file is http://pastebin.com/hdxdNK4d My Postfix master process configuration file is http://pastebin.com/YuCTq0JQ Dovecot -n gives me the following http://pastebin.com/05xixDtD I am trying to send an email to site(a)skippy.org.uk and site+test(a)skippy.org.uk (sending from an iCloud account), it works to site(a)skippy.org.uk (site(a)skippy.org.uk is a real email address), the lines from mail.log are as follows: > Mar 11 17:48:07 njoror postfix/smtpd[32706]: connect from mr11p26im-asmtp004.me.com[17.110.86.109] > Mar 11 17:48:07 njoror postfix/smtpd[32706]: Anonymous TLS connection established from mr11p26im-asmtp004.me.com[17.110.86.109]: TLSv1.2 with cipher DHE-RSA-AES128-GCM-SHA256 (128/128 bits) > Mar 11 17:48:08 njoror postfix/smtpd[32706]: 1BAF055AB6: client=mr11p26im-asmtp004.me.com[17.110.86.109] > Mar 11 17:48:08 njoror postfix/cleanup[32710]: 1BAF055AB6: message-id=<90594925-C294-4A38-8275-C23DA55A9308(a)icloud.com> > Mar 11 17:48:08 njoror postfix/qmgr[32599]: 1BAF055AB6: from=<philipmcgaw(a)icloud.com>, size=1513, nrcpt=1 (queue active) > Mar 11 17:48:08 njoror postfix/pipe[32605]: 1BAF055AB6: to=<site+test(a)skippy.org.uk>, relay=dovecot, delay=0.43, delays=0.34/0.01/0/0.09, dsn=4.1.1, status=SOFTBOUNCE (user unknown) > Mar 11 17:48:08 njoror postfix/smtpd[32706]: disconnect from mr11p26im-asmtp004.me.com[17.110.86.109] vs > Mar 11 17:49:23 njoror postfix/smtpd[32706]: connect from mr11p26im-asmtp004.me.com[17.110.86.109] > Mar 11 17:49:23 njoror postfix/smtpd[32706]: Anonymous TLS connection established from mr11p26im-asmtp004.me.com[17.110.86.109]: TLSv1.2 with cipher DHE-RSA-AES128-GCM-SHA256 (128/128 bits) > Mar 11 17:49:24 njoror postfix/smtpd[32706]: 33D2355AB9: client=mr11p26im-asmtp004.me.com[17.110.86.109] > Mar 11 17:49:24 njoror postfix/cleanup[32710]: 33D2355AB9: message-id=<2456DC97-4E3A-4A91-B3A0-CAFE056F116F(a)icloud.com> > Mar 11 17:49:24 njoror postfix/qmgr[32599]: 33D2355AB9: from=<philipmcgaw(a)icloud.com>, size=1249, nrcpt=1 (queue active) > Mar 11 17:49:25 njoror postfix/smtpd[32706]: disconnect from mr11p26im-asmtp004.me.com[17.110.86.109] > Mar 11 17:49:26 njoror postfix/pipe[32605]: 33D2355AB9: to=<site(a)skippy.org.uk>, relay=dovecot, delay=1.8, delays=0.63/0/0/1.2, dsn=2.0.0, status=sent (delivered via dovecot service) > Mar 11 17:49:26 njoror postfix/qmgr[32599]: 33D2355AB9: removed Looking at the lines from mail.log it looks like it thinks there should be a user called site+test(a)skippy.org.uk, this has been puzzling me for a while, I was wondering if any one on here could see what was wrong, and what I needed to change, Looking at a few examples and online guides I thought I had covered all the bases.

pop3 and dsync master-master replication issue causing duplicate delivery
by Burak Seydioglu 12 Apr '16

12 Apr '16

Hello, I am having an issue with a dsync master-master replication setup. Messages are not being marked current or deleted during the first session causing duplicate delivery when replication is running. It takes two logins and delete commands to get rid of the message. Topology: mda01.dcactive <---> mda01.dcpassive All interaction is happening on mda01.dcactive. I was running 2.2.13 and upgraded to 2.2.23 hoping it would help but I am still running into the same issue.

sis deduplication broken from 2.2.16 upwards

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, sis attachment deduplication is broken in 2.2.16 upwards. It is caused by this commit. https://github.com/dovecot/core/commit/664bf3e236c214aee86294483c379e4fa66c… in src/lib-fs/fs-sis.c function fs_sis_try_link() is comparation of inodes of hash files. Because fs_stat() after that commit use fstat() on open fd of temporary file instead of stat on filename. But that temporary file has differnt inode.

doveadm sync ignores -u option
by Max 12 Apr '16

12 Apr '16

Hi, Since I upgraded from 2.2.21 to 2.2.23, the user option -u seems to be ignored by doveadm sync, or at least it doesn't handle it correctly. If I run the following in the shell as user 'max': % doveadm sync -u foo(a)example.com -d doveadm(max): Error: User doesn't exist I get it to work if I set the USER environment variable to foo(a)example.com: % USER=foo(a)example.com doveadm sync -u foo(a)example.com -d # sync runs as expected. Kind Regards, Max

[Dovecot] Replication and public namespaces
by Markus Weippert 11 Apr '16

11 Apr '16

Hi, I'm having some issues with replicating public namespaces. Everything seems to work fine for private namespaces, but while importing some huge mailboxes (many small mails) into a public namespace via imapsync, something goes wrong. The expected mail flow is: old-server (imapsync)> new-server1 (replication)> new-server2 But then, dovecot seems to run into race conditions when the replications process tries to sync the same public mailbox under two or more different users at the same time. As a result, messages get duplicated, new-server2 sends those back to new-server1 which then starts to produce duplicates too. If I don't kill the processes in time and delete the faulty mailbox, they start to produce thousands of mails. In fact, server2 should not export messages at all, since it's not productive yet and does not get any mail except from the replication. The only thing getting logged (only few compared to the huge amount of duplicates produced): "dsync-server(user(a)example.com): Warning: Maildir /...: Expunged message reappeared, giving a new UID" Is there any way to fix this?

enable/disable shared namespace in passdb
by abi＠oleane.net 11 Apr '16

11 Apr '16

hello all i'm currently using passdb to enable and disable various namespaces conditionally : for example the following work namespace/inbox/inbox=no namespace/legacy_pfso/disabled=no namespace/legacy_pfso/inbox=no namespace/local_storage/disabled=no namespace/comboINBOX_local_pfso/disabled=no namespace/comboINBOX_local_pfso/inbox=yes but i can't get things like the following to work namespace/shared/disabled=yes -- the shared namespace is configured as shown below namespace shared { type = shared list = yes # children disabled = yes separator = / prefix = shared/%%u/ location = imapc:~/dovemail/shared/%%u/ } imapc_host = localhost imapc_port = 143 imapc_password = superpassword # either super or a dummy imapc_master_user = %u -- it seems the shared namespaces do not have names any more so they can't be modified dynamically is there a way to circumvent ? something i missed ? i'm running 2.2.22 but i can switch easily to 2.2.9 or any other version providing master_user or one of the variables that can let me know if a master login was performed is available in passdb the reason i'm doing this is so i can prevent long chains/loops from occuring : then accessed by imapc: , the passdb should disable the shared namespace so it does not produce (an)other imapc connection(s) thanks for your help alexis

Segfaults in indexer when after Maildir filename S value is updated
by Daniel Demus 10 Apr '16

10 Apr '16

Every now and then the S value in the Maildir filname is wrong, and is automaticcaly fixed by Dovecot while updating the index. It seems the indexer retains a handle pointing to the old filename and crashes immediately afterwards. The index is updated the next time the indexer is run, is this is only an annoyance and somethign that fills up the log. dovecot: indexer-worker(demus): Error: Maildir filename has wrong S value, renamed the file from /home/demus/Maildir/.INBOX.NYTimes/cur/1100506665.M177356P6525V0000000000000302I010100CD_0.server.demus.dk,S=12206:2,S to /home/demus/Maildir/.INBOX.NYTimes/cur/1100506665.M177356P6525V0000000000000302I010100CD_0.server.demus.dk,S=12658:2,S: 1 Time(s) dovecot: indexer-worker(demus): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x79988) [0xb6dc7988] -> /usr/lib/dovecot/libdovecot.so.0(i_warning+0) [0xb6dc7aa8] -> /usr/lib/dovecot/libdovecot.so.0(i_panic+0x64) [0xb6d6a948] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x9d27c) [0xb6ed627c] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x1c8) [0xb6ed67c0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x568a0) [0xb6e8f8a0] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_stream+0x68) [0xb6e5f3ac] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x56678) [0xb6e8f678] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_virtual_size+0x48) [0xb6e5efd4] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_precache+0x124) [0xb6ed7ee8] -> /usr/lib/dovecot/lib20_fts_plugin.so(+0xd5d4) [0xb6b6f5d4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_precache+0x40) [0xb6e5f804] -> dovecot/indexer-worker(+0x1ee8) [0x7f570ee8] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x68) [0xb6ddc5cc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x120) [0xb6dddd10] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x34) [0xb6ddc684] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x50) [0xb6ddc8b4] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x14) [0xb6d70c84] -> dovecot/indexer-worker(main+0xe8) [0x7f570880] -> /lib/libc.so.6(__libc_start_main+0x114) [0xb6bd2b54]: 1 Time(s) dovecot: indexer-worker(demus): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x79988) [0xb6e43988] -> /usr/lib/dovecot/libdovecot.so.0(i_warning+0) [0xb6e43aa8] -> /usr/lib/dovecot/libdovecot.so.0(i_panic+0x64) [0xb6de6948] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x9d27c) [0xb6f5227c] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x1c8) [0xb6f527c0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x568a0) [0xb6f0b8a0] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_stream+0x68) [0xb6edb3ac] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x56678) [0xb6f0b678] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_virtual_size+0x48) [0xb6edafd4] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_precache+0x124) [0xb6f53ee8] -> /usr/lib/dovecot/lib20_fts_plugin.so(+0xd5d4) [0xb6beb5d4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_precache+0x40) [0xb6edb804] -> dovecot/indexer-worker(+0x1ee8) [0x7f5eeee8] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x68) [0xb6e585cc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x120) [0xb6e59d10] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x34) [0xb6e58684] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x50) [0xb6e588b4] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x14) [0xb6decc84] -> dovecot/indexer-worker(main+0xe8) [0x7f5ee880] -> /lib/libc.so.6(__libc_start_main+0x114) [0xb6c4eb54]: 1 Time(s) Regards, Daniel Demus

mdbox and shared \Seen flag
by Dmitry Nezhevenko 09 Apr '16

09 Apr '16

Hi, I've just switched mail storage from maildir to mdbox and found it's very amazing. The only question I've is related to shared mailboxes. In the past I've had a few mailboxes that were shared between two users by just symlinking maildir. So everything was shared including flags and \Seen status. Now I want to get something like this. As far as I understand, "shared" namespace will keep \Seen flag private. So any suggestions how to make \Seen shared? My idea is to create some 'private' mdbox-based namespace that points to fixed location on server, that doesn't depends on username? Is it safe (in terms of locking, accessing indexes, etc)? I'm 100% sure that nobody except dovecot will access it. PS. It's latest version of dovecot. Thanks. -- WBR, Dmitry

Dovecot Proxy LTMP client connect to TCP port 0
by Wido den Hollander 09 Apr '16

09 Apr '16

Hi, I am trying to set up a Dovecot proxy which proxies through POP3, IMAP and LTMP towards a different Dovecot machine. On the proxy machine I use a MySQL database as a userdb and passwdb backend and it returns the proper information as described here: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy IMAP and POP3 works just fine, but with LMTP I run into a problem. On the 'proxy' machine Postfix is also running and it deliver locally to LTMP via Socket: virtual_transport = lmtp:unix:private/dovecot-lmtp Dovecot there is also configured to proxy LTMP: lmtp_proxy = yes service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } So far so good. A telnet to localhost 110 or 143 allows me to log in to the POP3/IMAP. When Postfix delivers the message locally to Dovecot through LTMP it tries to proxy it though. When doing so it tries to connect to TCP port 0 (zero). dovecot: lmtp(22580): Error: lmtp client: connect(mbox01.XXXX.nl, 0) failed: Connection refused I know I can return the 'port' field in the userdb query, but the same query is used for POP3, IMAP and LMTP. So that can't be hardcoded. I fixed it for now with a CASE statement in SQL: password_query = SELECT b.hostname AS host, NULL AS password, \ 'Y' AS nopassword, u.email AS destuser, 'Y' AS proxy, \ CASE '%s' WHEN 'lmtp' THEN 2525 WHEN 'pop3' THEN 110 WHEN 'imap' THEN 143 END AS port \ FROM User u, Backend b, Domain d \ WHERE u.domainID = d.domainID \ AND b.backendID = d.backendID \ AND u.email = '%u' %s is a variable containing the service Dovecot is trying to look up. This is however rather hacky. On my destination machine LMTP is listening on port 2525. Is there any way to tell the Dovecot LTMP client to connect to port 2525 by default? Thanks, Wido

Hi, the log file shows suspicious entries as follows: Apr 3 09:14:49 xxx dovecot: imap(user@domain): Error: fts_solr: Lookup failed: 400 Bad Request The tomcat7 log shows for this request: 10.0.0.234 - - [03/Apr/2016:09:14:49 +0200] "GET null null" 400 - Dovecot is latest 2.2.23 with a pretty standard FTS config copied from the wiki: mail_plugins = " acl fts fts_solr" fts = solr fts_solr = break-imap-search url=http://10.0.0.123:8080/solr/ Unfortunately I do not know (yet) which client action produces these log lines. "GET null null" seems not to be a sensible request in any case. Anyone seeing the same effect? Chris

Permissions for new folders
by David Cigánek 08 Apr '16

08 Apr '16

Hi, I have a problem with permissions for newly created folders in Dovecot. Everything worked fine until few days ago, when i did a little change in userdb lookup - but i don't know why it is causing problems. Server uses following directory structure: index - /data/mail/index mail - /data/mail/mail alt - /data/mail/archive all 3 on separate volumes, for performance reasons. Up until few days, i used following: # doveadm user dave(a)example.com field value user dave(a)example.com uid 13726 gid 1004 home /data/mail/mail/003/3726/da/dave mail mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/stub/index/data/mail/mail/003/3726/da/dave:ALT=/data/mail/stub/archive/data/mail/mail/003/3726/da/dave config is quite simple: mail_location = mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/stub/index%h:ALT=/data/mail/stub/archive%h passdb { driver = sql args = /data/mail/sql/dovecot-sql.conf.ext } userdb { driver = static args = gid=vmail } from SQL i get those fileds username domain password userdb_home userdb_uid userdb_quota_rule userdb_quota_over_flag For nicer paths, i created a symlinks /data/mail/stub/index/data/mail -> /data/mail/index /data/mail/stub/archive/data/mail -> /data/mail/archive so path /data/mail/stub/index/data/mail/mail/003/3726/da/dave is in fact in /data/mail/index/003/3726/da/dave In that setup, everything worked fine, but i didn't like those simlinks, so i altered the SQL query to return all paths in userdb_mail filed: # doveadm user dave(a)example.com field value user dave(a)example.com uid 13726 gid 1004 home /data/mail/mail/003/3726/da/dave mail mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/index/003/3726/da/dave:ALT=/data/mail/archive/003/3726/da/dave So everything is in fact the same but little nicer. But since then, newly created directories doesn't get the same permissions like parent folder as day should (2770), but instead they are created with 2700: # stat -c "%a (%A)" /data/mail/mail/ 2770 (drwxrws---) # stat -c "%a (%A)" /data/mail/mail/003 2700 (drwx--S---) I need to have there 2770 perms, especialy because when other user like this is created: user dave(a)example.com uid 13999 gid 1004 home /data/mail/mail/003/3999/da/dave Dovecot is unable to create directory /data/mail/mail/003/3999, because it doesn't have write permissions for group on /data/mail/mail/003. I can't find any reason for this behavior - is it something in Dovecot or am I doing something wrong?

Broken pipe with own dict server. Timing issue?
by martijn.list 08 Apr '16

08 Apr '16

Hi, I have created my own dict server (proxy:[<dict path>]:<destination dict>) to access a proprietary database. The dict server basically creates a listing socket on a separate thread and then waits for incoming requests with accept(handle, NULL, 0). When a request comes in (i.e., when accept returns the accepted socket fd), the request is handed over to a handler thread (from a thread pool). The handler thread then read from the input. The issue that I have is that if the read is done too fast after the accept, Dovecot reports a broken pipe: dovecot: auth-worker(19904): Error: write(/usr/share/test-server/tmp/test-dict) failed: Broken pipe This happens for almost all processes that try to access the dict server. However If I add some sort of delay between the accept call and read (for example a sleep), everything works. No broken pipe even after testing with a large number of parallel requests for a long time. Somehow it looks like if the first read is done too fast, it takes a long time to read the data. During this time it looks like all other Dovecot processes are no longer able to connect and report the broken pipe. With the artificial delay, everything works ok and I can see that multiple incoming request are handled by multiple threads so it looks like Dovecot uses multiple auth worker processes. If however one connection hangs on the read it looks like no Dovecot proccess is able to connect Any idea what might be causing the broken pipe in relation to timing of the read? Kind regards, Martijn

Own implementation of a dict server. Is dict lookup multi threaded or single threaded?
by martijn.list 08 Apr '16

08 Apr '16

Hi, I have created my own dict server (proxy:[<dict path>]:<destination dict>) to access a proprietary database. What happens if the dict server lookup is slow? for example because the lookup process takes some time? Does Dovecot access the dict proxy from multiple threads or is this a single threaded process? Kind regards, Martijn Brinkers

ETOOMANYREFS related errors
by Luis Ugalde 07 Apr '16

07 Apr '16

Hi, I'm starting to see, on a pretty standard Debian Jessie installation, some error messages that are apparently related to the ETOOMANYREFS errno. Firstly, the mail log shows this: dovecot: pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice And then the login process fails: dovecot: pop3-login: Internal login failure (pid=34388 id=1) (internal failure, 1 successful auths): user=<username>, method=PLAIN, rip=rip, lip=lip, session=<session> Is this something that Dovecot should be able to handle, or is it strictly Debian/libc/MySillyMistake related? #uname -a Linux server 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux #dovecot --version 2.2.13 #dpkg -l | grep -E 'dovecot-core|libc6|linux-image' ii dovecot-core 1:2.2.13-12~deb8u1 amd64 ii libc6:amd64 2.19-18+deb8u3 amd64 ii libc6-i386 2.19-18+deb8u3 amd64 ii linux-image-3.16.0-4-amd64 3.16.7-ckt20-1+deb8u3 amd64 Best Regards, Luis

lmtp_rcpt_check_quota = yes silently blocks mail if quota check fails
by Tom Sommer 07 Apr '16

07 Apr '16

I have a user which has a quota-check that fails with 'Internal error', if I enable lmtp_rcpt_check_quota, the mail is silently tempfailed. Actually it looks like lmtp_rcpt_check_quota=yes suppresses normal Info/Error logging, even on Director. The MTA just gets " 451 4.3.0 <xxxx(a)xxx.xxx> Temporary internal error (in reply to end of DATA command)" from the director, but nothing is logged with lmtp_rcpt_check_quota=yes, anywhere. -- Tom

doveadm sync -1 -R
by Lukas Kolbe 07 Apr '16

07 Apr '16

Hi, I’m migrating an old Zarafa-installation to a dovecot using mdbox and sis on Debian Jessie. To copy over the emails, I use doveadm backup on the new box - or more precisely: vmail# doveadm -v -o imapc_user=$user -o imapc_password=$pass -o imapc_host=$host -o imapc_features=rfc822.size -o imapc_port=993 -o mailbox_list_index=no -o imapc_ssl_verify=no backup -R -x "Public folders*" -x "Public folders/*" -u $user imapc: For each invoke of doveadm backup -R, the local (new) mailbox gets wiped and all mails are retransferred - so far, so good. I’d like to use "doveadm sync -1“ as per the manpage to keep the downtime short, however sync doesn’t like the -R option: sync: invalid option -- 'R' doveadm sync [-u <user>|-A] [-S <socket_path>] [-1fPU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> If I understand it correctly, without -R it would mean that doveadm sync would incorporate the changes from the local dovecot-mailbox into the remote imapc:-Mailbox, which is the opposite of what I want. Dovecot version is current head as of yesterday. Is what I’m trying to do even possible with doveadm sync? Kind regards, Lukas

What is dovecot.socket and do i need it?
by Hamy 07 Apr '16

07 Apr '16

Helloafter rebooting the server, i keep getting these errors in mail.err : Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 143, but it's not configured in Dovecot. Closing. Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 993, but it's not configured in Dovecot. Closing. Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 993, but it's not configured in Dovecot. Closing. And then dovecot refuses any connection. the problem is solved if i do a manual restart of dovecot.service. After some search, i found 2 different solutions, one suggesting disabling dovecot.socket completely, the other one adjusting its settings: https://sowhatisthesolution.wordpress.com/2015/04/27/upgrading-dovecot-debi… I also found an old thread in the mailing list that might be relevant: http://dovecot.org/list/dovecot/2012-March/134376.html The errors indeed seem to go away if i disable dovecot.socket . I would be grateful is someone could help me understand the role of dovecot.socket , and why that error happens and what is the right way to solve it? PS: I am using Ubuntu server 15.10 and dovecot package v2.2.18 Best Regards,

"Lost" e-mail after alternate partition offline
by Daniel van Ham Colchete 07 Apr '16

07 Apr '16

Hey guys! I've got a problem here and I wish you could help me. A drive failed here and went offline for some time. This was a alternate storage drive so it took a while (hours) for us to notice. There was a problem with DRBD also, so it didn't move to the redundancy, it just went offline. I was able to recover all the files there, but a few of my users still don't see their old e-mails, the ones that are supposed to be on the alternate storage. >From what I could troubleshoot here file are there, vmail user can access them, so it's not a permission issue, but a doveadm dump on the index file of each mail folder, won't show the e-mail at the alternate storage drive. So, they are there (at the filesystem), but they aren't (from a imap client). Is there a way to rebuild the dovecot.index file, re-adding everything back to each folder? Best, Daniel Colchete

namespace...mailbox doesn't exist

Hello list, I have a namespace called 'projects' which when clicked in Thunderbird (nonexistent in eM Client) yields the following error: "The current operation on 'projects' did not succeed.

Please let me know if any additional information is necessary. I'm thinking that the problem lies in lines 6/7 and 8/9 where Dovecot is looking for mdbox/sdbox. Eric

Migrating from Olde server to Dovecot
by Hendrik Velloen 06 Apr '16

06 Apr '16

Hi I am new to the mailing List, and was hoping to get some assistance migrating from an Old Cucipop + Sendmail server (running on a old Redhat v 7) to a new Dovecot setup. My new installation is Dovecot + Postfix. All is setup and working, however I want to trasnsfer the contents of the mailboxes from my old server to this new Dovecot setup.

Internal quota calculation error (redis), double mail delivery
by Tom Sommer 06 Apr '16

06 Apr '16

Sometimes my redis connection times out, both for pop3, imap and lmtp. I have no idea why, when I do a "doveadm quota recalc -u" it works just fine? I'm thinking the connection is lost somehow and not retried? Apr 06 15:42:00 lmtp(xxx(a)xxx.com): Error: redis: Lookup timed out in 30.000 secs Apr 06 15:42:00 lmtp(xxx(a)xxx.com): Error: Internal quota calculation error Apr 06 15:42:00 lmtp(xxx(a)xxx.com): Error: Internal quota calculation error Apr 06 15:42:00 lmtp(xxx(a)xxx.com): Info: xxxx: msgid=<xxxx(a)xxxx.com>: saved mail to INBOX Apr 06 15:49:23 lmtp(xxx(a)xxx.com): Info: xxxx: msgid=<xxxx(a)xxxx.com>: saved mail to INBOX <-- Same mail This happens a lot, and it's really bad, because the mail is actually saved correctly, but the error is reported back to the Director, causing the delivery to be retried by the MTA - so the mail actually lands *twice* in the user's inbox. Thanks -- Tom

LMTP with alias addresses
by davide marchi 06 Apr '16

06 Apr '16

Hi, my problem is this: if i use lmtp for delivery and lookup for real_virtual_user(a)mydomain.com all function perfectly and mails are delivered correctly (quota and presence of user also) but if i send an email to real_alias_address(a)mydomain.com LMTP service (it's an alias containing several users) dosen't find user. How can i resolve this problem? for completeness my system users is based on vpopmail userdb

Session ID separator change
by Timo Sirainen 06 Apr '16

06 Apr '16

LMTP is a but troublesome in that a single LMTP session can do multiple RCPT TOs, so the same session will end up delivering mails to multiple different users. This is causing trouble with stats process, because each delivery is using the same session ID for multiple different users, which causes errors about session ID duplication in stats process. So we'll need to make the session IDs unique, while still keeping it clear enough that they're part of the same original LMTP session (which is also visible in th Received: headers). I'm now thinking that the first recipient's delivery will have the original normal session ID (e.g. "ME3ZHCi+A1dUDQAAvAUe3g"), while the following recipients will have :2, :3, etc suffix (e.g. "ME3ZHCi+A1dUDQAAvAUe3g:2"). If somebody cares about parsing the original session ID from logs, they can just cut off the session ID from the first ':' character (because indexer-worker also adds its own :suffix). So now I'm mainly wondering if ':' is a good character? Has somebody already changed mail_log_prefix in a way that these additional ':' chars might break their log parsers (e.g. mail_log_prefix=%u:%s%{session}:%r).

Unable to login with iPhone?
by Jason Pruim 06 Apr '16

06 Apr '16

Hey Everyone, So I have my dovecot install up and running! I can receive mail from the outside, still dealing with a small issue with sending email, but I think that's an issue off needing to setup a relay... Right now though... My biggest issue is it won't connect to my iPhone... I can login with mail on my computer, and through round cube for webmail... But it gets stuck on "verifying"... I tried addingcram-md5 and digest-md5 to the auth_mechanisms but that didn't work... Any idea what I'm missing? Here is my doveconf -n: [ec2-user@ip-172-31-28-46 postfix]$ doveconf -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 4.4.5-15.26.amzn1.x86_64 x86_64 ext4 auth_mechanisms = plain login cram-md5 digest-md5 mail_location = maildir:/var/vmail/%d/%n/Maildir 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 ihave mbox_write_locks = fcntl namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl = required ssl_cert = </etc/ssl/certs/mailserver.pem ssl_key = </etc/ssl/private/mailserver.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } protocol lda { mail_plugins = " sieve" } [ec2-user@ip-172-31-28-46 postfix]$ If I try to telnet to port 993 from my local computer it connects, but won't let me login... Same on port 143... Any ideas? Thanks everyone for your help! I can't wait until I can actually help with the questions instead of just asking them!

dovecot squatter
by Gabriele Bulfon 05 Apr '16

05 Apr '16

Hi, on cyrus installations we have the squatter utility that can index full message bodies and headers incrementally, allowing to run the squatter from time to time to arrange for index changes. Is there anything similar in Dovecot? This is expecially useful for full searches in body message. Thanks for any help Gabriele ---------------------------------------------------------------------------------------- Sonicle S.r.l. : http://www.sonicle.com Music: http://www.gabrielebulfon.com Quantum Mechanics : http://www.cdbaby.com/cd/gabrielebulfon

New feature: HTTP API
by aki.tuomi＠dovecot.fi 05 Apr '16

05 Apr '16

Hi all! We are bringing out HTTP API for doveadm-server in master HEAD. This feature is experimental, and can be expected to have bugs in it and might not always work. If you feel like trying it out though, you can enable it in your configuration file: doveadm_api_key = some-string service doveadm { inet_listener http { port = 8080 } } To use the API, you can go to http://host:8080/doveadm. GET request will print out possible commands, along with their parameters. If you have set API KEY, you need to include it in the request as X-API-Key header. This API has been designed to resemble JMAP API since we are planning to implement it in future version. The rule of thumb is that all the commands work as they would on cli, so the parameters are more or less the same. There are few exceptions, like 'field' parameter in some mail/mailbox commands. Commands are executed by POSTin JSON to /doveadm. The JSON format is [ ["command",{"parameter":"value"},"opaque identifier"], ["command",{"parameter":"value"},"opaque identifier"], ["command",{"parameter":"value"},"opaque identifier"], ... ] Be warned though that even if it supports multiple commands, some commands still use i_fatal to terminate the server if they are unhappy. This will mean you will lose the whole result set, and get no output, so at this point it is safest option to run only one command at a time. If you run into problems or discover issues, please report them in the usual manner to us. Kind regards, Aki Tuomi Dovecot Oy

Environment Variable Expansion
by Tim Evers 04 Apr '16

04 Apr '16

System: Debian Jessie I'm trying to put an environment variable in the sql config like: password_query = SELECT userid AS user, crypt AS password, maildir as userdb_home, 500 as userdb_uid, 500 as userdb_gid FROM local_account WHERE userid = '%u' and mbox_host = '%{env:CLUSTERNAME}' \ and ( ( imap_aktiv='1' and '%s'='imap' ) or ( pop_aktiv='1' and '%s'='pop3' ) or ( sieve_aktiv='1' and '%s'='sieve' ) ) \ and aktiv_abruf='1' My variable is %{env:CLUSTERNAME} CLUSTERNAME is set through /etc/default/dovecot. I tried setting the import_environment config variable to TZ CLUSTERNAME but that changed nothing. When I execute this through a login attempt, I see the following in the tcpflow output: SELECT userid AS user, crypt AS password, maildir as userdb_home, 508 as userdb_uid, 503 as userdb_gid FROM local_account WHERE userid = 'te' and mbox_host = 'env:CLUSTERNAME}' and ( ( imap_aktiv='1' and 'pop3'='imap' ) or ( pop_aktiv='1' and 'pop3'='pop3' ) or ( sieve_aktiv='1' and 'pop3'='sieve' ) ) and aktiv_abruf='1' So %{env:CLUSTERNAME} was parsed to env:CLUSTERNAME} which is not what the doc (http://wiki.dovecot.org/Variables) says, and it also seems like the parser somehow sees this as a short variable (removing %+{). Any hints what might be happening here / how I can make it work. Regards, Tim

How to make quota_status policy to apply to postfix virtual aliases as well?
by Hamy 04 Apr '16

04 Apr '16

HelloI am setting up a postfix+dovecot setup and using quota-status service to reject mails for full mailboxes on smtp session, according to this: https://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ This is working fine and without any apparent issues. however, Postfix doesn't seem to consult the policy when you're using virtual alias addresses. a virtual alias, is the one that you usually define with virtual_alias_maps . what happens is that Postfix only verifies there is a corresponding value for the given email address and blindly accept it. And it seems smtpd_recipient_restrictions , only applies to the original email address and postfix does not consult that after applying virtual alias. Does any one have any idea how to solve this? is there a setting that i'm missing? or is there a better way to setup email aliases that solve this issue? Best Regards,

Problem with GSSAPI
by Luca Bertoncello 03 Apr '16

03 Apr '16

Hi list! I'm really puzzled... I have a Mailserver with Dovecot 2.2.9 (installed from Ubuntu 14.04-Repositories) and it works well with LDAP-Authentication agains the Active Directory. Now I want to use GSSAPI to allow the clients (with Thunderbird 38.7.1) to read E-Mails without giving a password. I configured Dovecot using these HowTos: http://mindref.blogspot.de/2011/02/dovecot-kerberos.html http://wiki.dovecot.org/Authentication/Kerberos But it does not work... In mail.log I can just see: Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libmech_gssapi.so Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Apr 3 09:52:26 mail dovecot: auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Apr 3 09:52:26 mail dovecot: auth: Debug: auth client connected (pid=2300) Apr 3 09:52:26 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.50.54, lip=192.168.50.3, session=<x8Sq5I8vsADAqDI2> and Thunderbird says that the Ticket was not accepted and I have to check if I'm logged into the Kerberos/GSSAPI subsystem. I checked with tcpdump and I see that Thunderbird does NOT send at all any request. Could someone help me? Thanks a lot! Luca Bertoncello (lucabert(a)lucabert.de)

Found 4 bugs in latest SquirrelMail related to IMAP and SMTP STARTTLS, Dovecot capabilities
by Tobias 03 Apr '16

03 Apr '16

This is a cross-post from the squirrelmail-devel list. It may be of interest if you want to run SquirrelMail and connect to Dovecot (and Postfix, possibly other servers) on a remote host using STARTTLS. BR Tobias -------- Forwarded Message -------- Subject: [SM-DEVEL] 4 bugs, IMAP and SMTP STARTTLS, Dovecot capabilities Date: Sun, 3 Apr 2016 04:27:56 +0200 From: Tobias <lists.zxinn(a)otaking.se> Reply-To: Squirrelmail Developers Mailing List <squirrelmail-devel(a)lists.sourceforge.net> To: squirrelmail-devel(a)lists.sourceforge.net Hello! I've looked for and have not seen any similar issues reported related to STARTTLS. Sourceforge wouldn't let me create an account or else I could have submitted bug reports directly. I'm using SquirrelMail 1.4.23 installed from latest FreeBSD Ports, together with PHP 5.6. I'm attempting to connect using STARTTLS to Dovecot 2.2.22 and Postfix 3.1.0. I've verified the code is not fixed for any of these four issues in the latest 1.5.2 SVN. Issue 2 is not as much of a problem in 1.5.2 as it is in 1.4.23 when using 'login' authentication. I connect to the IMAP and SMTP servers using their IP, but need to override the 'peer_name' to validate the certificate properly. New in PHP 5.6 is also that verify_peer defaults to TRUE, which means I need to either be able to set the peer_name, or disable verify_peer. I've found three issues in functions/imap_general.php, related to STARTTLS and Dovecot IMAP server, as well as one STARTTLS issue in class/deliver/Deliver_SMTP.class.php, class class Deliver_SMTP, function initStream. Issue 1: Stream options ($imap_stream_options) are not used with STARTTLS ($use_imap_tls = 2) in function sqimap_create_stream. The stream options are only used for $use_imap_tls = 1. How to fix: Add something like this: // set context options to allow for SSL option overrides @stream_context_set_option($imap_stream,$stream_options); Before trying to initiate the TLS session here: functions/imap_general.php :: function sqimap_create_stream 826: // start crypto on connection. suppress function errors. 827: if (@stream_socket_enable_crypto($imap_stream,true,STREAM_CRYPTO_METHOD_TLS_CLIENT)) { Issue 2: IMAP capabilities are only read once in function sqimap_create_stream (and subsequently used in sqimap_login to determine certain login options), however the capability list for Dovecot is not the same before and after STARTTLS. From Dovecot, before STARTTLS (telnet <local-ip> 143): * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready. From Dovecot, after successful STARTTLS (openssl s_client -starttls imap -connect <local-ip>:143): <SSL session info> --- . OK Pre-login capabilities listed, post-login capabilities have more. a capability * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN a OK Pre-login capabilities listed, post-login capabilities have more. How to fix: Issue "capability" command after successful STARTTLS to re-read the capabilities. Either as part of function sqimap_create_stream, or after call to sqimap_create_stream and before login options are checked in function sqimap_login. SquirrelMail 1.4.23 uses the return value with capabilities from function sqimap_create_stream to determine if 'login' is a viable option. Dovecot reports LOGINDISABLED prior to STARTTLS. (1.5.2 does not have this check for 'login'.) Issue 3: Multi-line response from the server to the AUTHENTICATE PLAIN (and likely cram/digest md5, possibly even login) are not accepted. The IMAP protocol allows the server to prefix responses which are incomplete with "*", and Dovecot uses this to report capabilities after successful login, but this is not handled by SquirrelMail's sqimap_login function. SquirrelMail reports: Unknown error: IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SEARCH=FUZZY SPECIAL-USE QUOTA The full output from Dovecot is: * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SEARCH=FUZZY SPECIAL-USE QUOTA A003 OK Logged in How to fix: Check if '*' is the first token in a response, and read another line from the stream. Possibly something similar to this: while (substr($read,0,1) == '*') { // OK so far.. $read = sqimap_fgets($imap_stream); } Issue 4: Identical to issue 1 but for SMTP. $use_smtp_tls = 2 and STARTTLS in class/deliver/Deliver_SMTP.class.php, class class Deliver_SMTP, function initStream, does not honor stream options.

SIS deduplication fails to create intermediate directories and funny permissions
by Jesus Cea 01 Apr '16

01 Apr '16

I have configured my system to use SIS, sharing the same same storage for all users, and offline deduplication. I have this in my "root" cron: """ 53 1 * * * /usr/local/bin/doveadm purge -A 16 * * * * /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue """ Yes, it is launched as "root" but I would expect doveadm drop privileges as soon as possible. This is working great, but from time to time I get this error message: """ Your "cron" job on babylon5 /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue produced the following output: Error: mkdir(/home/dovecot/buzones/attachments/dc/62/hashes) failed: No such file or directory """ Looks like doveadm is trying to create the "hashes" directory but the parent "62" doesn't exits yet. If I create that directory by hand and set permissions correctly, everything (seems to) work. Talking about this, I see something strange wit the permissions. All files and directories in SIS are created with "dovemail" user and group EXCEPT the "hashes" directory inside the newly created directory. That is: When I get the error message, I have this: """ drwx------ 7 dovemail dovemail 7 Apr 1 13:28 . drwx------ 237 dovemail dovemail 237 Mar 24 20:09 .. drwx------ 3 dovemail dovemail 3 Feb 29 02:30 1d drwx------ 3 dovemail dovemail 3 Mar 9 01:53 7f drwx------ 3 dovemail dovemail 3 Feb 29 02:30 88 drwx------ 3 dovemail dovemail 3 Feb 29 02:30 8d """ I create the missing directory by hand and change permissions.

"INBOX" a OK List completed. Then I add the namespaces: namespace inbox { separator = . prefix = inbox = yes hidden = no list = yes subscriptions = yes } namespace compat { separator = . prefix = INBOX. inbox = no hidden = yes list = no alias_for = } Then list output changes: a LIST "" "*" * LIST (\HasNoChildren) "."

Multiple IMAP Mailboxes and one collection folder
by Dieter Knopf 31 Mar '16

31 Mar '16

Hello, we use many IMAP folders and now we are searching for a way to display all mails inside this folders in one collecting folder. The advantage for us would be the possibility to view all new incoming mails in one folder. It would be possible to use the standard MAIL App on the iOS without problems. I could simply make a copy of all mails in one folder with Sieve, but then the Per-user Seen Flag would be useless, because the mail inside the folder is still unread. Is there a way to show some way of collecting folder for every user? Thanks Dieter

Dovecot plugin pthread issue
by qmail＠top-consulting.net 31 Mar '16

31 Mar '16

I am using FreeBSD 10.1 and Dovecot 2.2.22 with the Openchange plugin - https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu… (https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu…) The plugin compiles just fine and works up until when it tries to create a socket using nanomsg, which uses a pthread_create() call. At that point dovecot-lda just hangs indefinitely. I've read that -pthread must be included in all the components that might end up using it. So checking with ldd: nanomsg does include libthr ( pthread equivalent in FreeBSD ) openchange plugin also includes libthr dovecot-lda doesn't include libthr Would dovecot-lda also need to be compiled with -pthread ? Is it safe ? How can it be done ? Thank you!

Dovecot-LMTP and LDAP: passdb doesn't support credential lookups
by Niols 30 Mar '16

30 Mar '16

Hello, Sorry, this might be a newbish question, but I really can't get the answer by myself. I'm trying to setup a mail server using LDAP to authenticate users, and I keep receiving the errors: passdb doesn't support credential lookups passdb doesn't support lookups, can't verify user's existence when I send test mails to (existing) users. I'm already using the LDAP server for other purposes, and it's working fine. I can't (or I don't want to) give read access to the userPassword attribute, so I want to use a authentication bind: http://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds I've already managed to have postfix working with this LDAP server, the users (and their aliases) are correctly recognized. Postfix then sends the mails to Dovecot (2.2.13, Debian Jessie's version) with dovecot-lmtp. Here is my /etc/dovecot/conf.d/auth-ldap.conf.ext. I use the static driver for userdb, and the LDAP driver for passdb. passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=mail gid=mail home=/var/mail/%u } Here is my /etc/dovecot/dovecot-ldap.conf.ext file. hosts = localhost ldap_version = 3 dn = cn=dovecot,ou=services,dc=niols,dc=fr dnpass = a-random-password auth_bind = yes base = ou=people,dc=niols,dc=fr pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) I haven't set the user_filter and user_attrs values, since I thought these would only be usefull for userdb. I haven't set the pass_attrs value, since I don't see why it would be needed (I just need to be able to bind my user, right?). I can't auth_bind_userdn since the e-mail address aren't necessarily related in any way to the user dn. I assumed %u was going to be replaced by the user's full e-mail address. I tried to play a bit with these values to find a working configuration, without success. I tried to search myself on the LDAP server, using the provided dn and dnpass, and I succeeded. I tried to activate debug logs, but that didn't give me much more information (full debug log at the end of this e-mail). I think the problem is that passdb cannot find the user on the LDAP server, but I don't know why. I believe the problem is lying in my non-comprehension of what userdb and passdb actually do. I tried to find out by myself, and I'm here because I didn't manage to do so. I'm sorry if this post looks stupid. Any help and any comments of any kind would be greatly appreciated. Regards, Niols PS: Here is the full debug log that I get after sending a test message to test(a)niols.net (.net vs. .fr: this is not a mistake, I use my .net domain for testing purposes while I use my .fr domain for eveyday life) with swaks: lmtp(3208): Connect from local auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat auth: Debug: LDAP initialization took 0 msecs auth: Debug: master in: USER 1 test(a)niols.net service=lmtp auth: Debug: ldap(test(a)niols.net): passdb doesn't support credential lookups auth: Error: static(test(a)niols.net): passdb doesn't support lookups, can't verify user's existence auth: Debug: userdb out: FAIL 1 lmtp(3208): Error: user test(a)niols.net: Auth USER lookup failed lmtp(3208): Disconnect from local: Successful quit

CentOS RPM updates?

Has CentOS stopped distributing dovecot updates via yum? The current version there is 2.2.10 - which is now over two years old. The link on: http://dovecot.org/download.html <http://dovecot.org/download.html> to “RPMs for Fedora and RHEL/CentOS” http://packages.atrpms.net/dist/el6/dovecot/ <http://packages.atrpms.net/dist/el6/dovecot/> is also broken. Would be great if someone could please point me to alternative locations for authentic RPMs

talloc access after free error ntlmssp_server.c:457
by J Landwehr 30 Mar '16

30 Mar '16

Our new/fresh dovecot imap installation on CentOS (latest from yum repository, which is 2.2.10) is locking up with a panic on a consistent basis and denying service to subsequent clients. The behavior is repeatable. Have spent weeks debugging and trying different configurations with no success. Specific /var/log/maillog error messages are: 12:06:54 dovecot: auth: Error: talloc: access after free error - first free may be at ../auth/ntlmssp/ntlmssp_server.c:457 12:06:54 dovecot: auth: Error: Bad talloc magic value - access after free 12:06:54 dovecot: auth: Error: PANIC (pid 2570): Bad talloc magic value - access after free Our configuration is based on the instructions for NTLM authentication with our Windows 2012R2 AD/Domain server: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm <http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm> Here are the steps to reproduce: 1. Fresh boot of CentOS server, only configured for postfix/dovecot 2. Connect with Outlook 2016 12.0.4312.1000 32bit on Win7 via IMAP to this dovecot server 3. Any existing and new mail loads in OK to inbox - so authentication is working OK to AD domain server 4. Send an email to someone from Outlook 5. SMTP process completes, message is delivered - 6. dovecot immediately panics on servers, Authentication to dovecot no longer works 7. <systemctl restart dovecot> will hang until a <kill -9> on the “dovecot/auth” PID is performed The issue is with steps 6/7 immediately after 4/5- and is intermittent. Steps 1-3 always work OK, as do 4-5. Further, inbound emails received on this server when no IMAP client is running are always received just fine and dovecot doesn’t hang. Sometimes I have to send a few email messages with steps 4/5 before the issue with 6/7 happens. If I tail -f /var/log/maillog on the server, I can usually determine when 6/7 will fail because there is a line or two with: "dovecot: map: Disconnected: logged out message” being shown, even though the Outlook client is still open. After I see that Outlook closed an IMAP session, even though outlook is still running, I can send a message from Outlook and after it appears in my inbox, dovecot panics/hangs immediately Authentication is otherwise working, e.g. test with: /usr/bin/ntlm_auth —username=alice occasionally takes several seconds to respond, but is usually immediate response is always NT_STATUS_OK: Success (0x0) (I welcome tips to make ntlm_auth always respond more quickly!) I have tried adding lines to smb.conf like: win bind cache time = 300 win bind offline login = true No success I have also looked further into the detailed debugging logs and there is: dovecot: auth: Error: Go user=[alice] domain=[OFFICE] workstation=[pc1] len1=24 len2=290 dovecot: auth: error: login for user [OFFICE]\[alice]@[pc1] failed due to [Wrong Password] dovecot: auth: Error: GENSEC login failed: NT_STATUS_LOGON_FAILURE dovecot: auth: winbind(?,x.x.x.x,<XXX>): user not authetnicated: NT_STATUS_LOGON_FAILURE But I am not sure why there would be that error, since earlier IMAP sessions are working just fine with the same exact domain/username and password. It seems to be something about Outlook quickly opening up new simultaneous IMAP sessions with a CONT command, and NTLM authentication somehow fails with one of them, and panics. It always seems to be when sending an email. Like the process of either receiving a new msg in the inbox and/or also posting the just sent message into the Sent Items folder via IMAP (perhaps when it happens simultaneously, as in a message you cc yourself on) is somehow triggering this.

Dumb question: dovecot include file
by Jerry 29 Mar '16

29 Mar '16

Dovecot has an include file option. What I am not sure of is why those files use both a *.conf and *.conf.ext extension. I assume both types are included by using the !include <FILE>.conf or !include <FILE>.conf.ext syntax. -- Jerry

mailbox prefix

dovecot version 2.2.13 hello, I try to make a new server just for me after having old one working for ages with Dovecot, Fetchmail, Squirrelmail, Procmail making new one with above plus Postfix using Maildir structure. I am having a bit of trouble understanding exactly what the namespace and prefix are. Is the "private/" prefix an internal thing with Dovecot ? Or is it supposed to be a real directory ? I'm not quite sure how to properly address the INBOX in Procmail, Squirrelmail, Postfix config. for example am I supposed to say inbox is ".private/.INBOX" cheers zemlik

Migrating to dovecot from gmail apps
by Phil Lello 28 Mar '16

28 Mar '16

Hi, I'm considering migrating away from gmail for my (one-man) company, and I'm trying to decide if dovecot is the right option (I'm committed to self-hosting). I'm a developer, so happy to do my own tooling if needed. *Is there currently a good webmail interface to dovecot, or work-in progress?* If not, would a web interface be out-of-scope for dovecot? I want to use SAML for authentication, so a solution that relies on POP/IMAP doesn't meet my needs - unless I add Kerberos into the mix, which is an additional learning curve, and possibly not widely supported. *Is there currently a good web admin interface to dovecot, or work-in-progress?* If not, would a web interface be out-of-scope? Since I prefer using password-protected SSH keys for shell access, and don't want to tie myself to a laptop (and would hate to use vim on a 3G/4G tablet), I'd like to be able to add/remove aliases and play with SIEVE and ACLs through any available browser. *How's the work on sharing messages between folders progressing?* Finally, and I hope you don't mind me asking, are you aware of a good JAVA based alternative to dovecot? I quite like the idea of using lucene indexing on mailboxes, so reducing the number of dependencies has a certain appeal. Best wishes, Phil Lello

Enabling tcpwrappers
by kepa 28 Mar '16

28 Mar '16

Hi all, I would like use Dovecot with tcpwrappers enabled to control remote access using hosts.deny and hosts.allow. A google search gave this response from the listserve, but it is several years ago: http://www.dovecot.org/list/dovecot/2013-April/089455.html Are these instructions for configuring the conf files still valid? Mainly: /etc/dovecot/dovecot.conf login_access_sockets = tcpwrap conf.d/10-master.conf: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Also: Which version of Dovecot at least is needed to enable tcpwrappers? Does the tcpwrap option need to be enabled during configure and build or is it already (and enabled in any distro binary repositories)? And is it dovecot, imap, or imaps in the hosts.allow/deny file as the service name? Thanks! Kepa

I am not the only one. You can google around and find many run into this situation and no one could help. Most just delete the dovecot and postfix and start over again. However, I cannot afford that because it took me at least 3 months to setup dovecot correctly with postfix to use virtual users. I don't have the time to spend another 3 months to set it up. The problem lies with auth and I think this is the only issue and it has to be that something is missing either in the configs or a file was deleted or link to it was broken.

Hmm. I can't think of why dovecot wouldn't time out. I think maybe the problem is with your webmail system -- it's not detecting when a client connection goes away and releasing all the resources associated with that user. This is not a typical problem though -- most webmail software do not keep persistent IMAP connections open during a session unless they use some IMAP proxy. Are your IMAP connections connected to the webmail server or an IMAP proxy, and is that connection active (despite webmail user disappearing)? Joseph Tam <jtam.home(a)gmail.com>

Need help solving issue

Hi, I am using Dovecot 2.2.18 and have migrated from a 1.x versions. After this migration I had several errors and obsolete errors in logs. I fixed them and after all that I finally was able to run postfix and dovecot again. The problem I have facing right now is that in the mail logs and in the dovecot logs. I am getting auth errors. In mail log the postfix is spitting out: " fatal: no SASL authentication mechanisms" Dovecot is spitting this out "imap-login : Auth process broken (disconnected before auth was ready, waited 0 secs): ,user<>, the shows client ip, my server ip and then the 0 seconds connection etc. Error: auth: environment corrupt; missing value for DOVECOT_" That is what it spits out. I asked for help and many threads.I am using freebsd 10.2. I do use mysql for database. I need someone to explain what the error means and how I can fix it? Thank you for your time!

Re: Reappearing emails - IMAP trace
by Ron Cleven 26 Mar '16

26 Mar '16

>> > >> >A few days back, I sent an overview of this problem, but received no responses. Since then, I have run dozens of traces to isolate the problem, difficult because there are timing issues involved. I have finally nailed it down. If this is not the proper place to report such bugs or if someone knows that this bug has been fixed, please let me know. As I noted in my earlier post, we have been running Dovecot 2.2.10 with a pair of CentOS 7 boxes with replications for the past year. We have been quite happy with the performance and reliability. >> > >> >Recently we received a report that emails could reappear in the INBOX after being deleted. After running a pile of traces, I determined that the problem was strangely related to replications. For the purposes of this discussion, I will refer to the two symmetric replicating servers as A and B. Further, let us assume that during "normal" operation, all the emails are delivered to A via SMTP and are replicated to B. Under those assumptions, if the IMAP user connects to A (where the messages were originally delivered), there is no problem, at least no problem I was able to find. The problem I am describing only arises if the IMAP user connects to B. Connecting to B has never presented any other problems that I am aware of. >> > >> >The test for which I have provided the trace starts with a test mailbox containing only 3 unread messages in the INBOX. Moving 1 of the unread messages to Trash is all that is needed to reproduce the problem. Remember this is ONLY a problem if the IMAP sessions do not connect to the server to which the messages were originally delivered. Also, I found that there is a timing window. The critical IMAP commands are: >> > >> > UID STORE xxx +FLAGS.SILENT (\Seen) >> > UID MOVE xxx Trash >> > >> >If you introduce a large enough delay (I arbitrarily chose 5 seconds) between those two commands, there is no problem. Presumably this has to do with the two boxes syncing up some critical data structure. > What mailbox format do you use?

Would be a good idea to try anyway with v2.2.22.rc1 (which seems to be stable enough that I'll make v2.2.22 release soon). > > Anyway, I attempted a few times to reproduce it with your test but wasn't able to. I was out when you were kind enough to reply. To answer your question, we are using Maildir format. The trace I provided was based upon IMAP interactions with Roundcube (though the problem was reproducable with several mail clients). I left in a few more steps to make the trace look less contrived. However, I reduced it further to just a couple of connection sessions. What I found in that exercise that was not apparent to me in my prior posting was that the "STATUS INBOX" command that ultimately reveals the problem (it shows the message reappearing) only becomes "wrong" when it is done in a subsequent session. That is, even if I inject an artificially large delay after the "UID STORE" / "UID MOVE" commands before the "STATUS INBOX" command in the same session, that result is never "wrong". But, as soon as I open a subsequent IMAP session, the "STATUS INBOX" command then shows the problematic results. I have never dug into the Dovecot code base, but I assume this relates to how the session data is cached and how the replications update it. None of this is relevant if the problem has already been fixed, so I will endeavor to set up a couple of test boxes with the current version to verify. The link you provided does look quite hopeful. Thanks so much.

I had much the same situation where a user signed up with a roaming wireless carrier that assigned a new IP to the client whenever it got passed from one access point to another. Good fun when this person took a bus ride through the city, leaving orphaned connections in its wake. The IDLE disconnection timeout is hardwired in the Dovecot code http://wiki.dovecot.org/Timeouts It's set to the RFC minimum of 30min. You'll have to recompile Dovecot to lower this to a non-RFC compliant value. I'm not sure how this this will affect clients, but 30min seems to be overly generous. Joseph Tam <jtam.home(a)gmail.com>

NetApp NFS vs. ZFS and NFS for Maildir
by Alessio Cecchi 26 Mar '16

26 Mar '16

Hi, I'm evaluating to switch from NetApp to a ZFS appliance (like Qsan). Our setup is Dovecot, Maildir for email storage and NFS to share mailboxes (more than 30k users) across POP/IMAP and MX servers. NetApp NFS works fine also under high load but have some limitation for inode numbers per Volume and is expensive (but recently their prices have dropped). ZFS, I read, suggest to create many small Raid Group to increase IOPS, but this configuration (N Raid instead of one RAID-DP like NetApp) is more complex to manage, or not? Someone has experiences with ZFS and NFS(v3) in high load environments? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Hi guys, We have implement imap idle in web mail built by us to have push mail feature. IMAP idle working perfectly with browser notification and we are happy with it but having one issue with users who close the browser directly and never logout in that case there are number of idle connection which are not in use and users are unable to login once IP wise connection limit is reached. Dovecot is not closing connection which are not in use, is there any setting available which can help me to resolve this issue.

When I set the default_pass_scheme to MD5-CRYPT in my sql config file, and store an MD5-CRYPT password in the sql database, I invariably get password mismatch errors on login: Mar 24 19:40:30 server1 dovecot: auth: Debug: client in: AUTH#0113#011PLAIN#011service=imap#011secured#011session=25HcztQuwQBHCDBi#011lip=xx.x.xx.xxx#011rip=71.8.48.98#011lport=993#011rport=60609#011resp=<hidden> Mar 24 19:40:34 server1 dovecot: auth-worker(9443): Debug: sql(test1(a)xxxxxx.com,xx.x.xx.xx): query: SELECT email as user, password FROM virtual_users WHERE email='test1(a)xxxxxx.com'; Mar 24 19:40:34 server1 dovecot: auth-worker(9443): sql(test1(a)xxxxxx,xx.x.xx.xx): Password mismatch Mar 24 19:40:36 server1 dovecot: auth: Debug: client passdb out: FAIL#0113#011user=test1(a)xxxxxx.com The password in the database was created using doveadm pw command and is stored as: {MD5-CRYPT}$1$5QAeG70c$dP8y7XJVd.VxZBF/DvcAa0 I tried removing the {MD5-CRYPT} from the password string, but that didn't help. I have to be doing something stupid because this should just work! Any ideas from anyone? Thanks much, Dan

Replication issues master <-> master nfs backend
by William L. Thomson Jr. 24 Mar '16

24 Mar '16

I keep having some replication issues and not sure what can be done to resolve or correct. It does not seem to happen all the time, though for the last ~30 or so minutes and many messages seems to be happening consistent for me. I have 2 mail servers, basically clones, and thus master master replication. Most of the time things work fine. But many times an email or several will arrive on one, and never replicate to the other. I am not as concerned on the never replicating, as I am that the user never gets notified. Mail arrives on say server 1, users are checking mail on server 2, and they never see the email on server 2. This is not always the case, but its happening enough daily. I then log into one and run sync manually. Which usually syncs the mail on both servers, and then it arrives in the inbox. Here is an example, mail is on mail2, but not mail1. I am checking email on mail1 so I am not seeing the 1 email. Mail1 /home/wlt-ml/.maildir/new: total 0 Mail2 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673024.7643.mail2 Then I manually log into mail2 and run this command, though usually I can run it from either side, and just change the name to the other server. doveadm sync -u "*" remote:mail1 And then I end up with the missing email on mail1, and it arrives in my email client shortly there after Mail1 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673051.M838843P26735.mail1,S=8502,W=8678:2,T I have no idea why it does this. It seems to happen when when a full sync has taken place per doveadm replicator status wlt-ml. There does not seem to be any settings to force a full vs fast sync more often. No clue if this is even a full vs fast issue or other. I think it tends to happen more when people stay connected to the imap server. I had a theory that closing the email client and opening it again will get dovecot to sync. I believe this is still the case, but not able to confirm 100%. Also users are reporting closing Thunderbird. I can see them logging out and back in in the logs, but email does not replicate or show till I run doveadm sync manually. Tempted to have cron invoke that on the regular, but seems very hackish and likely will have its own issues doing that. Since its not the right way or how things were designed. Not sure if this is a bug or what. Hopefully miss-configuration on my end. Open to any feedback, advice, etc. I can provide replicator configuration but its pretty straight forward and mostly copy/paste from the replication page. Replication works, just seems it is not triggered to replicate at times or something. dovecot --version 2.2.22 (fe789d2) -- William L.

Allowing for multiple recipient_delimiter characters?
by Aaron Lindsay 23 Mar '16

23 Mar '16

Postfix allows the recipient_delimiter configuration parameter to contain multiple characters, splitting on the first such character it encounters. For example, if using 'recipient_delimiter=+-' both aaron+foo(a)example.com and aaron-bar(a)example.com would be delivered to aaron(a)example.com. Is anyone opposed to changing dovecot's handling of recipient_delimiter so that it's the same as that of postfix? If not, I am willing to rebase/merge/address review comments on Lennart Weller's patch[1] to get this functionality upstream. While I think aligning with postfix' behaviour would be convenient for those of us who run a server using both dovecot and postfix, would this break any other common use cases I'm not aware of? Thanks! -Aaron [1] - http://dovecot.org/pipermail/dovecot/2015-February/099660.html (I've talked with Lennart off-list, and he's OK with me working to get his patch merged, as long as I attribute his work to him, but doesn't have the time to work on it himself right now)

protocols.d/ dir empty?

22 Mar '16

(I hope I'm doing this right) Hey there. I have a problem with the dovecot protocols. When I do /telnet 127.0.0.1 143/ it gives me a connection refused error. I looked in the wiki and then after trying /doveconf protocols listen /I realized that I don't have any protocols.//I went in //usr/share/dovecot/protocols.d/ and it's empty. How can I fix that?

multiple imapc settings in different namespaces
by abi＠oleane.net 22 Mar '16

22 Mar '16

hello all i assume this question must have already been asked, but i'm looking for a way to circumvent which might work specifically on my system. the version can be any available version between 2.2.9 and 2.2.22 (i'm testing with both of the above and no other ) i'm using imapc in 2 different namespaces. in both cases, the imapc_host is local, and a custom passdb program is expected to handle proxying to different servers. one of the case should proxy to a different legacy platform, and the other is used for shared mailboxes. is there any way at all to be able to tell which is which in passdb ? i don't care about the password, i can use a login prefix or suffix, different ports, different master passwords, ssl, maybe a different protocol name or auth method... somehow i've seen in the source code there is a namespace "owner" but did not manage to change this parameter. i guess it is used internally. anything else ? thanks a lot for any help you can provide best regards @abi

sieve - editheader - edit in place
by Hajo Locke 22 Mar '16

22 Mar '16

Hello, i do some tests with sieve editheader extensions. deleteheader and addheader are working, but i noticed that new headerlines are always prepended to current header. So new lines can be found always on top. I am looking for a possibility to edit a headerline in place, without moving the new line to top of stack(replaceheader?). It is not looking good if a Subject-Line suddenly moves to top of header. Is there a possibility for me? Thanks, Hajo

doveadm sync/backup doesn't sync the metadata?
by Heiko Schlittermann 21 Mar '16

21 Mar '16

Hello, in a current migration project we want to migrate from Cyrus to Dovecot. The Cyrus server stores expiry information as ANNOTATIONS. On the Dovecot side I've set up the metadata/annotations plugin and it is working. But 'dovecot backup …' doesn't seem to sync these metadata? Did I miss something here? Shouldn't the metadata be part of the backup? (I'm using the latest 2.2.22 for sync purposes, as the stock dovecot just crashed when used as 'doveadm backup …') Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Understand the UID value in mailbox debug
by Tobi 21 Mar '16

21 Mar '16

Hi list we have a client who complains that mails from a certain sender are always put into his spamfolder. Our strong guess is that this is an issue with the webmail (Roundcube), but I need some help in understanding the output from dovecot's mailbox-debug. In order to narrow down the source of the problem we activated the mailbox-debug from Dovecot. Now we can see that the mail is moved into the spamfolder. But the strange thing is that a UID is logged which does not exist on the mailserver The following log is the "move" of the mail into the spamfolder Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW copy from INBOX: box=INBOX.Spam, uid=58, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW delete: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imapREMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW expunge: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 I do not understand whose UID this is, as it does not exist on the server. Does dovecot create temporary UID or something like that? Or is it more a process ID? Thanks and regards tobi

Re: Setting up public mailboxes - user not found
by Marti Markov 20 Mar '16

20 Mar '16

Hey, I actually went with the method suggested by Steffen Kaiser of creating a separate userdb because I use LDAP and I have an OU which contains all the public mailboxes and was just easier. I setup the userdb like so: userdb { args = /etc/dovecot/dovecot-ldap-shared_mailboxes.conf.ext driver = ldap override_fields = mail=maildir:/home/vmail/Public/.%n } Now when I send an email to office3(a)xxx.com I don’t get any errors and it delivers the message to the office3(a)xxx.com: root@mail:~# ls /home/vmail/Public/.office3/new/ 1458427035.M781836P21781.mail.xxx.com,S=2571,W=2630 1458427705.M750112P23338.mail.xxx.com,S=2501,W=2559 But from any mail client I try I don’t seem to be able to list anything in the Public directory. Am I missing something in the configuration?

http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz.sig + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+. - Single instance storage support wasn't really working in v2.2.16+ - dbox: POP3 message ordering wasn't working correctly. - virtual plugin: Fixed crashes related to backend mailbox deletions.

TLS handshake issue
by John Oliver 18 Mar '16

18 Mar '16

dovecot-2.0.9 on CentOS 6.7 The system in question is not connected to the Internet, so I can't copy-and-paste. I have to type anything required :-( Brand-new out-of-the-box install with a really minimal dovecot.conf including: service imap-login { inet_listener imaps { address = 192.168.1.10 port = 143 ssl = yes } } ssl_cert=</etc/pki/tls/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_key =</etc/pki/tls/private/dovecot.pem That's very, very similar to an existing dovecot server on an old VM I need to replace. Certs are self-signed, I know that's a horrible thing to do, but right now we don't have any choice. I'm connecting with Apple Mail 8.2 running on OS X 10.10.5, another thing we have no choice about :-/ The Apple Mail just sits there stupidly. It's "Connection Doctor" just helpfully reports that it can't establish a connection. I can use 'openssl s_client -showcerts -connect mail:143' and see what I expect to see. The dovecot log with lots of verbosity enabled tells me: imap-login: Info: Disconnected (no auth attempts): rip=192.168.1.200, lip=192.168.1.10, TLS handshaking: Disconnected auth: Debug: auth client connected (pid=21006) imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2002, ret=1: SSLv2/v3 read client hello A [192.168.1.200] And that's it... those lines get repeated every minute that Mail is running. I'm not seeing anything in any logs that even hints at what it's unhappy about, or any way to increase verbosity any more. Any hints appreciated! -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Released Pigeonhole v0.4.13 for Dovecot v2.2.22.
by Stephan Bosch 18 Mar '16

18 Mar '16

Hello Dovecot users, Here is the final v0.4.13 release of Pigeonhole for Dovecot v2.2.22. Nothing changed since the RC. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.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

Trouble getting vnd.dovecot.filter and filter visible/usable...
by Tolbert, Joshua P 17 Mar '16

17 Mar '16

Hello, I’m trying to make vnd.dovecot.filter available both globally and for users through sieve, but I haven’t had much luck getting things to work right. Sieve scripts won’t validate and vnd.dovecot.filter never shows up in the managesieve capability list. I’ve spent lots of time looking for where problems could be, but I’m out of ideas…So I’m asking you guys. In the protocol lmtp section, I’m defining mail_plugins = $mail_plugins sieve, however I’ve tried it without $mail_plugins too…No luck that way either. Any help/advice would be much appreciated. Thanks! Cheers, Josh

Looking for way to monitor dsync, confirm it is or isn't running
by Rich Wales 17 Mar '16

17 Mar '16

I am syncing two Dovecot sites using the dsync function. I would like to be able to run some sort of periodic health check to confirm that dsync is (or is not) running properly between the two sites, and alert me if dsync is failing or lagging excessively. Does anyone know of a tool to do this? (If possible, something I can set up to run periodically in Nagios?) Thanks for any suggestions. Rich Wales richw(a)richw.org

Xi has a new home
by Stephan Bosch 17 Mar '16

17 Mar '16

Hi, The automatic package builder Xi has moved to system within the Dovecot infrastructure. This also means that the repositories are available at a new host name: xi.dovecot.fi. The old host name still works and is a CNAME pointing to the new venue. I expect the old domain to be active for years to come. So, there is no need to update your /etc/apt/sources.list right away. Still, it is a good idea to do so. I've updated the wiki accordingly. Regards, Stephan.

Re: spamc during dovecot-smtp delivery?

[cc'ing the list for posterity] also sprach Tolbert, Joshua P <jtolbert(a)illinois.edu> [2016-03-16 21:46 +0100]: > I’ve been working on a Postfix/Dovecot/sieve mail server migration > (from Sendmail/Dovecot/procmail) and ran in to a similar problem > to one you talked about a while ago on the dovecot mailing lists. > Did you ever find a good solution for running spamc as the > destination user in sieve? If you did, mind sharing? Thanks! I've never had a problem again since upgrading to Debian jessie, but I also think that the problem's solution was installing a NSS cache, because the deadlocks seemed to take place between Spamassassin and libnss-pgsql2. Transport from Postfix to Dovecot is lmtp:unix:private/dovecot-lmtp (no idea how to do that with Sendmail or why you'd want to use Sendmail) and then Dovecot's sieve is configured to run a filter using /etc/dovecot/sieve.before.d: require [ "vnd.dovecot.filter"]; filter "spamc" [ "--no-safe-fallback" ]; which is enabled in conf.d/90-sieve.conf with sieve_before = /etc/dovecot/sieve.before.d sieve_global_extensions = +vnd.dovecot.filter sieve_plugins = sieve_extprograms and in conf.d/90-sieve-extprograms.conf sieve_filter_bin_dir = /etc/dovecot/sieve-filter and then I made a simple symlink from /etc/dovecot/sieve-filter → /usr/bin/spamc Spamassassin starts with --create-prefs --helper-home-dir --allow-tell and the final step is to integrate the mail user database (vmm in my case) with libnss to provide spamassassin with a way to identify home directories. I use libnss-pgsql2. The /etc/nss-pgsql.conf file I use is available here: http://bugs.debian.org/818465 A successful delivery then looks like this: postfix/smtpd[29778]: connect from mail1.smtp.mailserver4.de[62.216.179.241] postfix/smtpd[29778]: 6D2F74024E: client=mail1.smtp.mailserver4.de[62.216.179.241] postfix/cleanup[32593]: 6D2F74024E: message-id=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> postfix/smtpd[29778]: disconnect from mail1.smtp.mailserver4.de[62.216.179.241] dovecot: lmtp(3570): Connect from local spamd[2140]: spamd: connection from localhost [::1]:57032 to port 783, fd 6 spamd[2140]: spamd: setuid to xxxxxxx%yyyyyyyyyy.zz succeeded spamd[2140]: spamd: processing message <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> for xxxxxxx%yyyyyyyy.zz:70032 spamd[2140]: spamd: clean message (-1.9/5.0) for xxxxxxx%yyyyyyyy.zz:70032 in 3.0 seconds, 10222 bytes. spamd[2140]: spamd: result: . -1 - BAYES_00,DKIM_SIGNED,DKIM_VALID,HEADER_FROM_DIFFERENT_DOMAINS,HTML_MESSAGE,RCVD_IN_DNSWL_NONE scantime=3.0,size=10222,user=xxxxxxx%yyyyyyyy.zz,uid=70032,required_score=5.0,rhost=localhost,raddr=::1,rport=57032,mid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>,bayes=0.000000,autolearn=ham autolearn_force=no dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) copy from (file): box=INBOX, uid=30613, msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>, size=10945 dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) QLZ6IoJ/6lbyDQAARsnb6w: sieve: msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>: stored mail into mailbox 'INBOX' postfix/lmtp[3569]: 6D2F74024E: to=<xxxxxxx(a)yyyyyyyy.zz>, orig_to=<aaaaaa(a)bbbbbbb.zz>, relay=ambassador.madduck.net[private/dovecot-lmtp], delay=5, delays=2/0.02/0.01/3, dsn=2.0.0, status=sent (250 2.0.0 <xxxxxxx(a)yyyyyyyy.zz> QLZ6IoJ/6lbyDQAARsnb6w Saved) dovecot: lmtp(3570): Disconnect from local: Successful quit Hope this helps… -- @martinkrafft | http://madduck.net/ | http://two.sentenc.es/ "the public is wonderfully tolerant. it forgives everything except genius." -- oscar wilde spamtraps: madduck.bogus(a)madduck.net

Hi all, I got a question if its possible to subscribe a mailbox from another user, who contains non mutf7 valid chars in his mailbox path.

Plugin "last-login" - Log SMTP-AUTH information
by Benjamin Hück 16 Mar '16

16 Mar '16

Hello all, we are using the Plugin "last-login" [1] to update user's last-login timestamp or the timestamp of the last incoming message in a MySQL backend. Would it be possible to expand the plugin to also log the timestamp of the last smtp-auth attempt/successful process? Currently in our settings, a smtp-auth request (port 587) is forwarded by postfix to a dovecot backend server for authentication. I couldn`t find out the developer of the plugin otherwise I had contact them immediatly.

New dovecot user needs installation help
by Jason Pruim 16 Mar '16

16 Mar '16

Hey Everyone, So I just setup my first dovecot install with postfix running for the mail server… I can telnet into my dovecot install and login just fine with my user locally… But when I try to add the account from my phone, computer, or telnetting from my local computer, it just hangs and eventually kicks back a generic error saying it can’t be added… Where can I start looking? I’m hosted with amazon web services and I’m waiting on them to approve my request to white list my IP on my instance, but that should only restrict my ability to send email out on port 25… I should still be able to operate locally… According to the firewall on amazon port 143 and 993 are both allowed from any IP address into the server (All outbound traffic is currently open until I get it working) I’m thinking it’s something easy, and I can handle pointers! I don’t necessarily need my hand held the entire way… At least not yet… Here is the output of my dovecot -n: [ec2-user@ip-172-31-22-222 log]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 3.14.48-33.39.amzn1.x86_64 x86_64 mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [ec2-user@ip-172-31-22-222 log]$ Let me know if there is anything else you need, or where to go from here!

Reappearing emails - IMAP trace
by Ron Cleven 16 Mar '16

16 Mar '16

A few days back, I sent an overview of this problem, but received no responses. Since then, I have run dozens of traces to isolate the problem, difficult because there are timing issues involved. I have finally nailed it down. If this is not the proper place to report such bugs or if someone knows that this bug has been fixed, please let me know. As I noted in my earlier post, we have been running Dovecot 2.2.10 with a pair of CentOS 7 boxes with replications for the past year. We have been quite happy with the performance and reliability. Recently we received a report that emails could reappear in the INBOX after being deleted. After running a pile of traces, I determined that the problem was strangely related to replications. For the purposes of this discussion, I will refer to the two symmetric replicating servers as A and B. Further, let us assume that during "normal" operation, all the emails are delivered to A via SMTP and are replicated to B. Under those assumptions, if the IMAP user connects to A (where the messages were originally delivered), there is no problem, at least no problem I was able to find. The problem I am describing only arises if the IMAP user connects to B. Connecting to B has never presented any other problems that I am aware of. The test for which I have provided the trace starts with a test mailbox containing only 3 unread messages in the INBOX. Moving 1 of the unread messages to Trash is all that is needed to reproduce the problem. Remember this is ONLY a problem if the IMAP sessions do not connect to the server to which the messages were originally delivered. Also, I found that there is a timing window. The critical IMAP commands are: UID STORE xxx +FLAGS.SILENT (\Seen) UID MOVE xxx Trash If you introduce a large enough delay (I arbitrarily chose 5 seconds) between those two commands, there is no problem. Presumably this has to do with the two boxes syncing up some critical data structure. It takes a short time for the message that was moved to Trash to reappear in the INBOX. The trace initially shows the number of messages going from 3 to 2 when the message is moved to Trash, but a second or so later, the message count goes back up to 3. Interestingly, the reappearing message shows back up as Unseen in the INBOX but a duplicate copy of it stays in Trash as Seen. Dragging unread messages to Trash may not be polite, but it is technically acceptable. Regarding the trace below , CR's show up as \r, LF's show up as \n, and each line starts with S or C depending upon whether it is from the Server or Client.

syncing mailboxes with dsync after switchover
by Sergey Schwartz 16 Mar '16

16 Mar '16

Gents, I'm relocating mailboxes to a new server. Before switching over to a new server I ran syncing a few times without any issues first I sync files with rsync from the old server to have a local copy, then I sync mailboxes with dsync /usr/bin/doveadm -Dv sync -u $MBOX -R "sdbox:/srv/vmail/temp/srv/srv.bgoperator.ru/${MBOX}:DIRNAME=DbOx-mAiLs" After switching over smtp transport and running dsync as above a few mailboxes were deleted dsync(xxx): Warning: Deleting mailbox 'INBOX': UID=1 already exists locally for a different mail: GUIDs don't match (c005a206e1c6e756f02700003a8929e2 vs 0ba1c03796f5dc524c6d0000b4ca29ec) dsync(xxxx): Warning: Deleting mailbox 'INBOX': UID=8855 GUID=80d5841f0fe2e35677630000b4ca29ec is missing locally dsync(xxxxx): Warning: Deleting mailbox 'INBOX': UID=7508 already exists locally for a different mail: GUIDs don't match (1e03d72074d8e756403700003a8929e2 vs 1dc47a3ac5c4e7562a290000b4ca29ec) dsync(xxxxxx): Warning: Deleting mailbox 'INBOX': UID=8238 GUID=2a6a803bd33fe156f85e0000b4ca29ec is missing locally and a few other mailboxes seemed to fail to sync dsync(xxxxxxx): Warning: Mailbox changes caused a desync.

VS: New dovecot user needs installation help
by Aki Tuomi 15 Mar '16

15 Mar '16

Can yoi run doveadm log errors too? ---Aki TuomiDovecot oy -------- Alkuperäinen viesti --------Lähettäjä: Jason Pruim <pruimj(a)gmail.com> Päivämäärä: 15.3.2016 4.50 (GMT+02:00) Saaja: dovecot(a)dovecot.org Aihe: New dovecot user needs installation help Hey Everyone, So I just setup my first dovecot install with postfix running for the mail server… I can telnet into my dovecot install and login just fine with my user locally… But when I try to add the account from my phone, computer, or telnetting from my local computer, it just hangs and eventually kicks back a generic error saying it can’t be added… Where can I start looking? I’m hosted with amazon web services and I’m waiting on them to approve my request to white list my IP on my instance, but that should only restrict my ability to send email out on port 25… I should still be able to operate locally… According to the firewall on amazon port 143 and 993 are both allowed from any IP address into the server (All outbound traffic is currently open until I get it working) I’m thinking it’s something easy, and I can handle pointers! I don’t necessarily need my hand held the entire way… At least not yet… Here is the output of my dovecot -n: [ec2-user@ip-172-31-22-222 log]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 3.14.48-33.39.amzn1.x86_64 x86_64 mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [ec2-user@ip-172-31-22-222 log]$ Let me know if there is anything else you need, or where to go from here!

dovecot wiki...
by Andrew McGlashan 15 Mar '16

15 Mar '16

Hi, Just want to know if this is a problem at my end (in my browser), or if it is something else. When I copy text from the wiki, the page changes to an edit one; that is very, very annoying. How can I stop this if it is normal dovecot wiki behaviour and what do you think I might look at in my browser if it isn't? I'm never likely to want to edit the wiki any time soon. Thanks AndrewM

Logging the TLS cipher suite

Hi, could it be possible to log the TLS cipher suite as Postfix does? This is a typical TLS Dovecot log line: imap-login: Login: user=<user(a)acme.com>, method=DIGEST-MD5, rip=1.2.3.4, lip=4.3.2.1, mpid=19671, TLS, session=<Jsvr46wt2c1ScQfY> This is the Postfix equivalent postfix/smtp[59723]: Anonymous TLS connection established to mail.acmne.com[1.2.3.4]:25: TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits) -- Ciao, luigi / +--[Luigi Rosa]-- \ We're not surrounded, we're in a target-rich environment!

Timout for LDAP connection
by Gordon Grubert 11 Mar '16

11 Mar '16

Hi, we are using a round robin dns record for connections to our ldap system. This works fine for almost all cases. In particular, for dovecot does this mean, when an ldap server is stopped, dovecot instantly reconnects to another ldap server. But when the network connection to the active ldap server is broken, dovecot sticks to the failed ldap server. Is there any possibility to define a connection timeout? This is our current configuration for the ldap connection: # 2.2.devel (2d8f665): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (0de2a19) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.3 uris = ldaps://LDAP-SERVER dn = BINDDN dnpass = BINDPASS auth_bind = yes ldap_version = 3 base = BASEDN scope = subtree user_attrs= ATTRIBUTES user_filter = USERFILTER pass_filter = PASSFILTER iterate_filter = ITERATEFILTER Best regards, Gordon -- Technischer Leiter & stellv.

Troubleshooting mailbox problems
by Nick Bright 11 Mar '16

11 Mar '16

Greetings, I'm running Dovecot 2.0.9 on my CentOS 6 server, for several thousand mailboxes. Recently, I've had several reports of "my mailbox is suddenly empty, where'd my mail go?" I've enabled debug logging, but I'd like to make sure I have the best level of debug to see things like "delete message" commands? I've configured in logging: auth_debug = yes auth_debug_passwords = no mail_debug = yes plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_group_events = yes mail_log_fields = uid box msgid size } Does this look like a good start? I really think it's a client side problem, but sometimes end users always want to blame the server; and proof must be shown e.g. "Look, here's the log, you're sending delete commands." At which point, we can proceed with dealing with their software problem.

Setting up public mailboxes - user not found
by Marti Markov 10 Mar '16

10 Mar '16

Hi all, This is the first time I use the dovecot mail list so I’m sorry if I forget something. My problem is that for some reason I can get public mailboxes to work. I have setup the directory Public, the folders and the cur,tmp and new folder in them: Public | |- .office3 | |- cur |- tmp |- new |- dovecot-acl Here is my dovecot conf: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.32-xxxx-grs-ipv6-64 x86_64 auth_default_realm = xxx.com auth_mechanisms = plain login mail_gid = vmail mail_home = /home/vmail/%d/%n mail_location = maildir:~/Maildir mail_plugins = acl mail_uid = vmail 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 ihave namespace { list = yes location = maildir:/home/vmail/xxx.com/Public:INDEXPVT=~/Maildir/Public prefix = Public/ separator = / subscriptions = yes type = public } 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 = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile sieve = ~/.dovecot.sieve sieve_before = /etc/dovecot/sieve/dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)xxx.com protocols = " imap lmtp sieve" service auth { unix_listener auth-client { group = Debian-exim mode = 0660 user = Debian-exim } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener lmtp { mode = 0666 } } ssl = required ssl_cert = </etc/dovecot/xxx.com.pem ssl_key = </etc/dovecot/private/xxx.private.pem ssl_key_password = yyyyyyy userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = acl sieve } protocol imap { mail_plugins = acl imap_acl } The error I’m getting is that LMTP can’t deliver to office3(a)xxx.com because the user could not be found.

I’m not sure but should Dovecot skip this and check the Public folder first before checking LDAP? Another part of my setup is Exim4. Here is the transport part: dovecot_lmtp: driver = lmtp socket = /var/run/dovecot/lmtp return_path_add #maximum number of deliveries per batch, default 1 batch_max = 200 And here is the auth part: dovecot_login: driver = dovecot public_name = LOGIN server_socket = /var/run/dovecot/auth-client # setting server_set_id might break several headers in mails sent by authenticated smtp. So be careful. server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif So any tips on how to fix this would be great.

zlib plugin doesn't add "Z" flag to Maildir filename
by Tom Sommer 10 Mar '16

10 Mar '16

I enabled zlib compression, so new mails are saved compressed. Now I want to convert the old mails to gzip with the find and gzip command, but now I don't know which files are already gzip compressed by dovecot. Shouldn't zlib_save itself add Z to the Maildir flags? As suggested in the compress guide on http://wiki2.dovecot.org/Plugins/Zlib ? -- Tom

v2.2.22 release candidate released
by Timo Sirainen 10 Mar '16

10 Mar '16

http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz.sig There are some larger changes here, especially to doveadm to make it support HTTP API. There's still time to do smaller tweaks to the API, so let us know if you have some improvement ideas. Note that the API was designed to look mostly like JMAP, which we're planning to implement also for v2.3. The plan is to fork v2.3 development tree soon. + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+.

Using dsync to synchronize laptop against remote server
by Dato Simó 10 Mar '16

10 Mar '16

Hello! I’m thinking of changing the way I sync mail to my laptop, and I have a couple questions about my intended setup. In brief, my plan is: instead of running offlineimap against various IMAP accounts (my personal one included), I will run fetchmail on my private server, and classify mail with Sieve there. Then I’ll run a local Dovecot on my laptop, and do a master/master replication from my personal server/account with dsync. I have two quick questions about this (I have never used dsync before): 1. Reading the manual page, it seems that I probably want stateful synchronization (-s flag). Not having used it before, I’m curious about what lag I can expect. Does it compare to an IMAP IDLE/IMAP NOTIFY connection? Or is it asynchronous / with a timer? 2. I assume modifying my local Maildirs with e.g. Mutt is... a big no-no? Instead, should I always force Mutt to go through the local IMAP server? Many thanks in advance, -d

Re: Dovecot stops responding when I update SSL certificate
by HotSlots Webmaster 10 Mar '16

10 Mar '16

Time to put an end to this saga... I had an issue that Dovecot refused to serve an updated SSL certificate - one that Postfix had no issue with. Though I quadruple-checked that the cert file and private key file were correct, in the end I simply directed both cert and key files to the file I was using for Postfix (which had both the cert and private key). That worked. Darned if I know what it didn't like about the other files, but I'm back in business with the new cert. Thanks for the responsiveness from Aki. Steve L

Replication not working
by Simon Pierre Desrosiers 10 Mar '16

10 Mar '16

Hello, I am trying to setup replication between two Mac OS X El Capitan Server. I have added the field as I could understand from the replication page of dovecot and from a few poste in the mailing list. The mac uses the system user _dovecot as main system account. I have setup ssh keys between the two systems for the two _dovecot servers. SSh works fine from the terminal. But yet, I get these messages in the log file : Mar 09 20:18:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:18:44 doveadm: Error: Host key verification failed. Mar 09 20:18:44 dsync-local(submit): Error: read(_dovecot(a)laposte.mycompagny.com) failed: EOF Mar 09 20:18:44 dsync-local(submit): Error: Remote command returned error 255 Mar 09 20:23:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:23:44 doveadm: Error: Host key verification failed.

I have a few things about which I am not sure. We configure port 12345, but nothing listen on that port. The doveadm_password, what is it exactly ? Should I use a distinct account than _dovecot for synchronisation (all the fields that need to be added for replication) ? Here is my configuration, any help would be appreciated : # 2.2.5: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 15.3.0 x86_64 hfs auth_mechanisms = cram-md5 digest-md5 gssapi

Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.
by Stephan Bosch 10 Mar '16

10 Mar '16

Hello Dovecot users, Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only with warnings. That is the primary reason for this new release. However, there are also a few significant changes as listed below. When no significant problems are reported, a definitive release will follow closely after Dovecot v2.2.22 is released. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

segfault in imap and doveadm
by Joe Beaubien 07 Mar '16

07 Mar '16

Hi everyone, Dovecot keeps on segfaulting on me and I am unsure why. This setup has been running for 5 years and has given me very little trouble. I am running Dovecot 2.1.7, setup with mdbox. The imap process keeps on segfaulting for the same account (makes me think maybe an email or folder of that account is problematic). My big issue is that force-resync also causes doveadm to segfault. Here is the mail.err file I am getting: Mar 7 12:34:36 mba kernel: [ 1955.486324] imap[5663]: segfault at 0 ip 00007ff1c1bd0b5e sp 00007fffd8599a40 error 4 in libdovecot-storage.so.0.0.0[7ff1c1b51000+fb000] Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Sara/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:37 mba dovecot: imap(document): Error: mdbox map /mba_data/emails/document/storage/dovecot.map.index corrupted: map_uid=284393 refcount too low Mar 7 12:34:37 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:39 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:42 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/_EE - a verifier/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:43 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:48 mba kernel: [ 1967.972883] imap[5688]: segfault at 0 ip 00007f058ebc9b5e sp 00007fff9baa7c00 error 4 in libdovecot-storage.so.0.0.0[7f058eb4a000+fb000] Mar 7 12:34:49 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:43:44 mba dovecot: imap(document): Error: indexer disconnected unexpectedly Mar 7 12:43:44 mba dovecot: indexer: Error: Indexer worker disconnected, discarding 119 requests for document Mar 7 12:48:31 mba kernel: [ 2790.363755] doveadm[6586]: segfault at 0 ip 00007f1b2023fb5e sp 00007fff4e8ce200 error 4 in libdovecot-storage.so.0.0.0[7f1b201c0000+fb000] Mar 7 12:49:10 mba kernel: [ 2829.203900] doveadm[6604]: segfault at 0 ip 00007fa0d16e4b5e sp 00007fff1b89f480 error 4 in libdovecot-storage.so.0.0.0[7fa0d1665000+fb000] First line is imap segfaulting.

questions regarding zlib plugin
by Götz Reinicke - IT Koordinator 07 Mar '16

Hi, faced with a current space problem on our dovecot 2.2.18 server, I thought about using the zlib plugin. My questions: - is it really as simple as adding the options to the conf files as described in the docs :) ? http://wiki2.dovecot.org/Plugins/Zlib - As this just compresses new messages; dose anybody has a sort of simple cron or whatever script or best practice how to compress existing maildir mails? The doc is a bit complicated to me at that point... Thanks a lot and regards . Götz

It's possible it's generating ephemeral DH keys. In a previous post to this list, I note that the run time to generate these keys can vary wildly, and gets worse with longer keys. Sometimes you get lucky, and you'll generate then quickly, sometimes it takes a long while (minutes). http://dovecot.org/pipermail/dovecot/2015-November/102447.html Try running openssl dhparam -noout 2048 to see how it varies for you. If what I suspect is true, you can try using shorter keys. A followup post suggest a way you can precompute the key Joseph Tam <jtam.home(a)gmail.com>

Thank you for your suggestion! As much as I hate Outlook (Look Out!), there are loads of people using really old versions; 2003 is no longer supported, but loads of people use 2007. Thunderbird can be expected to be far more up to date. Implementing features to work with older clients will always be a problem. Just a simple example, almost unrelated here, but this is either wrong by TB or wrong by Outlook (versions 2007, 2010 and 2013 that I know of). When the IMAP server sends a message, OL will pop up a window that requires the user to acknowledge the message via a popup. TB just pops up the message in the normal 'new mail' notify if that is configured and it might be lost if notify isn't set to show. Either way, the implementation is different b/w the two client products. Is OL right or is TB right... IMAP doco says that the message should be made to be acknowledged by the client; OL's version can't easily be ignored or missed, but TB's can easily be missed. But TB's implementation is more user friendly if the server wants to keep sending messages from time to time. I considered using this for MOTD type stuff and maybe random inspirational or motivational messages; even to remind or inform users to do certain things [one example in the dovecot wiki is to advise that the vacation message is still active]. A TB notification is next to harmless, but an OL one needs to be acknowledged every time, which would be very painful. Anyway, the point is that if a feature is added for OCSP stabling support, you couldn't really expect older versions of Look Out to comply with it (even though M$ could patch it easily, they care less about older versions than getting people to subscribe to Office 365 these days).

Implementation of TLS OCSP Stapling
by dovecot＠flut.demon.nl 06 Mar '16

06 Mar '16

Hi all, About a year ago, Torsten already asked for OCSP stapling (http://dovecot.org/pipermail/dovecot/2015-April/100632.html) Unfortunately, there was no answer to his question. Now RFC 7633 ("TLS Feature Extension", https://tools.ietf.org/html/rfc7633, a.k.a. "Must Staple") has landed, revocation is getting serious! I personally would like to embed all my TLS certificates with the must-staple extension. The great project Let's Encrypt already supports it: https://github.com/letsencrypt/boulder/pull/1224 I'm aware most MTAs don't really care about the certificate, but big players as Google take TLS encryption very seriously: https://googleblog.blogspot.nl/2016/02/building-safer-web-for-everyone.html So I would like to know if Dovecot is planning to feature OCSP stapling. That way I know for sure my "must staple" certificates can be used by Dovecot. And in my opinion, every TLS offering daemon should be up to par to the capabilities of TLS.. Not lag behind :) What's your opinion on this matter? Thanks in advance for any anwser! Greets, Osiris

dovecot local indexes and multiple servers
by alex 05 Mar '16

05 Mar '16

Hi, I've been testing mdbox with local indexes on our nfs based directors + multiple imap/lda/pop3 server setup. The performance is noticeably better than maildir with indexes on nfs, so I'd like to make this work. About the possible direction to other servers the wiki says that it will create a new index 'on the fly'. That is true, but after the index is recreated, Thunderbird (imap) re-downloads all the messages and sees all those messages as unread again! This is probably quite logical as the message status is only kept in the indexes, but this is not very customer friendly. Is there a way to avoid this problem? I'd rather not manually sync those local indexes between our servers. In fact, I was planning on deleting (old) indexes when a user moved to another server or even if they haven't checked their mail for XX days. with up to 10Gb mailboxes the indexes themselves can get up to 20-40Mb for a mailbox. that amounts to quite a lot of storage for 200k+ users. Thanks, Alex.

It's time to renew the SSL certificate, so I did (same CA). The new certificate works fine in Apache and Postfix. But when I update Dovecot to use the same certificate, and restart the server, Dovecot stops responding to connects. I have triple-checked that the ssl_cert and ssl_key files are correct - all I did was change the names in the conf file. There's nothing in the log. I have tried various SSL tests but either they don't work (unspecific error) or they tell me nothing is wrong (and show the correct certificate.)

Dovecot stops responding when I update SSL certificate
by HotSlots Webmaster 05 Mar '16

05 Mar '16

Dovecot 2.2.18 CentOS 6.7 (x86_64) Plesk 12.5.30 I have had Dovecot working fine with SSL for nearly two years now. It's time to renew the SSL certificate, so I did (same CA). The new certificate works fine in Apache and Postfix. But when I update Dovecot to use the same certificate, and restart the server, Dovecot stops responding to connects. I have triple-checked that the ssl_cert and ssl_key files are correct - all I did was change the names in the conf file. There's nothing in the log. I have tried various SSL tests but either they don't work (unspecific error) or they tell me nothing is wrong (and show the correct certificate.) I am running out of time to find a solution to this - what else can I look for? The one difference for the certificates is that I opted for one with a SHA256 root rather than SHA1 root. I have separately used a tool to verify that the certificate and private key match.

Dear All, I'd like dovecot-lda (deliver) to post a message to a public mailbox. It doesn't seem to work when I just use the -m parameter with the IMAP-Mailbox path, e.g. Public/info . What parameters are required? Do I have to change the headers with formail in any way? TIA! - Chris

Found bug in quota-status + patch
by Thierry Coppey 03 Mar '16

03 Mar '16

Hello, I've found a bug in the quota-status util (Dovecot 2.2.21, and probably below): it always return OK (sufficient quota) because it fails to load the user properly. More specifically, the branch " if (quser == NULL) return 1; " in src/plugins/quota/quota-status.c:59 is always taken. (at least with postgresql backend, test your config with the (adapted) command below: printf "recipient=mailbox(a)example.com\nsize=10000000000\n\n" | nc inet:mailstore.example.com 12340 it should reject, unless you have no quota, or more than 10G). Therefore it is pointless to configure the quota-status service as described in http://wiki2.dovecot.org/Quota because of that bug: the mail would be always accepted from the client and rejected at the end of the (Postfix) processing by lda. It is possible to reject directly at SMTP level when the mailbox is full using Postfix and main.cf: smtpd_recipient_restrictions = ... reject_unauth_destination, ... check_policy_service inet:mailstore.example.com:12340 smtpd_end_of_data_restrictions = check_policy_service inet:mailstore.example.com:12340 However there remain a *small inconsistency* as lda will count the size of message including headers whereas smtpd_end_of_data_restrictions seems not to count them towards the message size (or additional headers might be added by other preprocessing e.g. antispam etc...) I propose the patch below to fix quota-status. Could an expert double-check that it doesn't have memory leaks? (it shouldn't but I'm not yet comfortable enough with Dovecot memory management). Best regards, Thierry C.

Dual certificate
by Jean-Baptiste Vignaud 03 Mar '16

03 Mar '16

Hello all; Is anyone knows if it's possible to have a dual certificate setup on dovecot like in postfix or apache ? i tried to add several crts in local name section : local_name imap.server.tdl { ssl_cert = <server_rsa_crt.pem ssl_key = <server_rsa_key.pem ssl_cert = <server_ecdsa_crt.pem ssl_key = <server_ecdsa_key.pem } but it seems that dovecot takes the last one (ecdsa) and that rsa cert is not used. to check if booth are working, i check with openssl: openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-RSA-AES128-GCM-SHA256 for rsa and openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-ECDSA-AES128-GCM-SHA256 for ecdsa In apache we have to duplicate the cert / key lines one for rsa, one for edcda. In postfix, we have some specific ecdsa conf keys. So is there a way to do the same in dovecot ?

user configuration question
by Eric Abrahamsen 02 Mar '16

02 Mar '16

I've been using mbsync to sync this email account to a local Dovecot installation. I used to use Gmail, through Google Apps, and a while ago switched the account to self-hosting. I didn't want to upload years' worth of old email to my old server, so I've had two accounts in my MUA: one talking to the local Dovecot account for the old emails, and a second talking directly to the server for the new emails. I'd like to sync the new account to Dovecot as well, and I'm having trouble wrapping my brain around how to configure the two side-by-side accounts in Dovecot (I know there are other solutions to this, but I'm also just trying to figure out how this works). What I don't grok is the exact effect of the different username fields in the passdb file, and how they combine with username_format. Right now my dovecot.conf has this: passdb { driver = passwd-file args = username_format=%u /etc/dovecot/passwd } userdb { driver = static args = uid=eric gid=users home=/home/eric/.mail/%d/%n username_format=%u default_fields = mail=maildir:/home/eric/.mail/%d/%n/mail } And /etc/dovecot/passwd: eric@ericabrahamsen.net:{PLAIN}password:eric@ericabrahamsen.net Say I want to keep my existing mail where it is, and have all the new mail go into ~/.mail/ericabrahamsen.net/eric-new/mail. Ie, when mbsync connects to the local Dovecot, it does so with the username eric-new(a)ericabrahamsen.net. Now, in Dovecot's conf, do I change the email address in the first field of /etc/dovecot/passwd, or the third field, or both? And, if it isn't too much trouble, what is the difference between the two? Thanks! Eric

Dsync induces redundant mail after rapid append/expunge repeatedly
by 潘信傑 02 Mar '16

02 Mar '16

I meet the problem about dsync with expunge. The problems is expunged mail would reappear after dsyncing and it is easily to reproduce. Environment Settings: - Two servers(serverA, serverB) both enabled plugin "*replication"* - And more detail get by "dovecot -n" show below Reproduce flow: - Run two processes pA and pB both would run in while loop - pA(All behavior is on Draft mailbox and all on serverA): - Clean "Draft" mailbox of userA - Run the following imap command of userA - imap save (save new mail to Draft) - imap delete (delete old mail on Draft) - imap expunge * - Check if draft only have one email (it would be failed in about 50 loops)* - pB(Send mail to serverB): - Send new mail to userA (which would be save in INBOX) It would be easier reproduce by increasing server loading. I have found something - T he expunge changes from server A in dsync connection don't send immediately, these expunge changes appear after 1~2 dsync connection over. - The replicated mail is generated from serverB and sync back to serverA so expunged mail reappeared. dovecot -n (ServerA) #

Setup changes 1.x to 2.x -- custom POP3 account handling required.
by Andrew McGlashan 02 Mar '16

02 Mar '16

Hi, Previously I did /special/ processing for some email accounts; if a particular file existed in the user's home directory, then I caused the account to use /var/mail/$USER file for POP -- otherwise it used IMAP. Now, because I adjusted the setup for POP only, IMAP still worked perfectly well. Some users have both POP and IMAP access for various reasons. The special POP processing was done using a shell script [1] in place of: /usr/lib/dovecot/pop3 - which in turn called the normal binary once setting up the environment. Now, I have been forced to upgrade my Debian from squeeze-lts to wheezy and the dovecot setup is quite different. How can I implement my /wrapper/ script for POP handling now? Here is my current setup with dovecot -n ... # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 7.9 mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" service imap-login { inet_listener imap { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } } ssl = required ssl_cert = </etc/exim4/exim.crt ssl_key = </etc/exim4/exim.key userdb { driver = passwd } [1] This is the content of the original wrapper script: #!/bin/sh if [ -f $HOME/.use-mbox-for-pop3s ]; then export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER export USER_INBOX=/var/mail/$USER if [ -f $USER_INBOX ] then export USER_INBOX_GROUP=$(stat -c %G $USER_INBOX) if [ $USER_INBOX_GROUP != $USER ] then ( date ls -l $USER_INBOX chown Debian-exim:$USER $USER_INBOX ls -l $USER_INBOX ) >> /var/log/usr-lib-dovecot--pop3-affinity.log fi fi else if [ -d $HOME/Maildir ]; then export MAIL=Maildir:$HOME/Maildir else export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER fi fi # Finally execute the imap/pop3.

dsync issues due to Prefix difference?
by Mark Little 02 Mar '16

02 Mar '16

Hi everyone, I'm hoping I am just missing something obvious - but I cannot seem to get a one-way migration dsync working between two Dovecot servers because the Prefix configuration is different. I am doing a migration from our old Dovecot servers to some new cPanel based ones. Source: 2.2.15 Dest: 2.2.21 Here is the debug output for the sync: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_sieve_plugin.so doveadm(testuser(a)example.ca): Debug: Effective uid=1322, gid=1322, home=/khstor3/khmail-mailboxes/l/li/example.ca/testuser doveadm(testuser(a)example.ca): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir doveadm(testuser(a)example.ca): Debug: maildir++: root=/khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir, index=, indexpvt=, control=, inbox=/khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir, alt= doveadm(testuser(a)example.ca): Debug: Namespace : Using permissions from /khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir: mode=0777 gid=default stdin: is not a tty dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: INBOX guid=f055ac07d79cad508a7a000075e38adc uid_validity=1353555159 uid_next=2085 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Junk guid=703a8b1d51ceab56f91e0000667eee40 uid_validity=1391566942 uid_next=1 subs=yes last_change=0 last_subs=1454100049 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Trash guid=9bee9f0f2aacb65039260000b171e44d uid_validity=1353555163 uid_next=25 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Drafts guid=4d03661058a0f1524f240000e9d81ad0 uid_validity=1391566936 uid_next=1 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Sent guid=99ee9f0f2aacb65039260000b171e44d uid_validity=1353555161 uid_next=4 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX guid=6460141741cfab5643470000afb0d608 uid_validity=1454100291 uid_next=2064 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX.Trash guid=6360141741cfab5643470000afb0d608 uid_validity=1454100290 uid_next=12 subs=yes last_change=0 last_subs=1454100289 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX.Sent guid=6260141741cfab5643470000afb0d608 uid_validity=1454100289 uid_next=2 subs=yes last_change=0 last_subs=1454100289 dsync-remote(testuser(a)example.ca): Error: Couldn't find namespace for mailbox Junk I believe the problem is because on the source we have no prefix set, but on the destination it has INBOX as the prefix.

Alternative storage backend for Dovecot
by Oleksandr Natalenko 01 Mar '16

01 Mar '16

Hi. We have corporate Dovecot setup with GlusterFS as file storage. We store maildirs on GlueterFS share, mounting it via NFS. Mounting share via native GlusterFS FUSE client introduces visible performance overhead. Also, NFS mount does not provide us with HA. That's why I have an idea to use GlusterFS C API to access maildirs share. I'd like to preserve maildir structure, but get access to it not via FS mount point but with GlusterFS C API calls. I've discovered that Dovecot source tree has src/lib-fs infrastructure with fs-posix implemented on top of it. Is that the right place to start from? GlusterFS C API calls are POSIX-like, so they could be easily used as substitutions for VFS ops. Could such a backend be implemented as separate plugin? Are there any examples of alternative storage backend to look at? Thanks. Regards, Oleksandr.

Inconsistent mdbox index while running doveadm altmove
by Ricardo Machini Barbosa 01 Mar '16

01 Mar '16

Hello, I was performing doveadm altmove for one account while this mailbox was being accessed. Dovecot version: 2.2.21 Mailbox format: mdbox Command: doveadm altmove -u user1(a)domain.com.br before 360d This command took about 5 minutes to finish and during the execution I found some log messages: Feb 25 19:57:51 dovecot: imap(user1(a)domain.com.br): Error: mdbox map /var/mail/user1/mdbox/storage/dovecot.map.index corrupted: Unexpectedly lost INBOX uid=77 map_uid=76 Feb 25 19:57:51 dovecot: imap(user1(a)domain.com.br): Internal error occurred. Refer to server log for more information.

I had to execute doveadm force-resync -u user1(a)domain.com.br INBOX to recovery this mailbox, but losing all e-mail's flags. I should do some kind of lock before running the command altmove ? Regards, Ricardo

severe fork() problems with new dovecot server
by J. Niklas 01 Mar '16

01 Mar '16

Hi all, I am getting to you because I am pretty desperate by now. Please read this and share your ideas. I set up a new Mail server with roughly 750 active accounts on it, based on the usual dovecot+postfix+amavis+sql based vmail setup. This is not the first time I did something like this, but admittedly my largest setup so far. I took my time to setup everything pretty straight and stable and migrated all accounts in time with almost no glitches using imapc and pop3c. Things started out smoothly - until the first business morning when the log suddenly began to pop messages like these: dovecot: master: Error: service(imap): fork() failed: Resource temporarily unavailable dovecot: master: Error: service(pop3): fork() failed: Resource temporarily unavailable The error is not confined to a certain service. There are no other messages in dmesg or syslog which could help in closing in on the root cause. The server always runs at load around 0.4 to 0.5 and has plenty of RAM and Disk, too. Of course I checked resource limits and cranked up everything I could possibly think of to numbers that should easily suffice: /etc/security/limits.conf: daemon soft nproc 2048 daemon hard nproc 3128 dovecot soft nproc 2048 dovecot hard nproc 3128 vmail soft nproc 2048 vmail hard nproc 3128 vmail soft nofile 32768 vmail hard nofile 49152 /etc/systemd/system/dovecot.service.d/ulimits.conf: [Service] LimitNOFILE=65534 However, all my attempts on resolving the problem were futile so far. To work around the problem I implemented a log watcher which constantly looks for the fork failure and dumps some debug info before restarting dovecot to make the problem "go away" - until dovecot hits whatever barrier there is again. Here are today's numbers I gathered from this: > forkdump_03-01_09-42: pop=3, imap=446, all=503, postfix:22, sys: 716 > forkdump_03-01_10-09: pop=9, imap=444, all=510, postfix:28, sys: 741 > forkdump_03-01_10-42: pop=5, imap=450, all=507, postfix:25, sys: 748 > forkdump_03-01_11-18: pop=5, imap=451, all=512, postfix:29, sys: 757 > forkdump_03-01_11-48: pop=3, imap=474, all=511, postfix:37, sys: 765 > forkdump_03-01_12-23: pop=7, imap=444, all=511, postfix:22, sys: 752 > forkdump_03-01_12-53: pop=3, imap=444, all=503, postfix:24, sys: 747 > forkdump_03-01_13-21: pop=3, imap=458, all=504, postfix:31, sys: 766 > forkdump_03-01_13-41: pop=4, imap=451, all=505, postfix:23, sys: 755 > forkdump_03-01_14-35: pop=5, imap=436, all=502, postfix:31, sys: 768 > forkdump_03-01_14-59: pop=3, imap=445, all=501, postfix:27, sys: 764 > forkdump_03-01_15-28: pop=6, imap=452, all=507, postfix:25, sys: 769 There you see the number of pop3 and imap childs in the process list as well as the total number of all dovecot processes and all postfix processes, summarized directly after the fork problem appears in the log. The last column is the sum of all processes in the system. Here is a run where the numbers are measured as the server approaches the last entry in the list above. > 15:26:15: pop=3, imap=432, all=485, VSZ: 14353k, postfix:30, sys: 749 > 15:26:30: pop=4, imap=435, all=490, VSZ: 14497k, postfix:30, sys: 754 > 15:26:45: pop=3, imap=439, all=492, VSZ: 14560k, postfix:28, sys: 754 > 15:27:00: pop=3, imap=444, all=497, VSZ: 14711k, postfix:28, sys: 760 > 15:27:15: pop=4, imap=442, all=496, VSZ: 14673k, postfix:25, sys: 756 > 15:27:30: pop=4, imap=444, all=497, VSZ: 14721k, postfix:25, sys: 757 > 15:27:46: pop=3, imap=446, all=498, VSZ: 14756k, postfix:25, sys: 758 > 15:28:01: pop=3, imap=446, all=497, VSZ: 14718k, postfix:24, sys: 756 > 15:28:16: pop=3, imap=455, all=507, VSZ: 15018k, postfix:25, sys: 767 > 15:28:18: pop=3, imap=455, all=507, VSZ: 15018k, postfix:25, sys: 767 > 15:28:20: pop=3, imap=452, all=504, VSZ: 14931k, postfix:25, sys: 764 ---- service(pop3): fork() failed: Resource temporarily unavailable ---- > 15:28:22: pop=4, imap=452, all=505, VSZ: 14954k, postfix:25, sys: 770 > 15:28:24: pop=4, imap=452, all=505, VSZ: 14954k, postfix:25, sys: 770 > 15:28:26: pop=4, imap=451, all=504, VSZ: 14925k, postfix:25, sys: 769 > 15:28:28: pop=5, imap=451, all=506, VSZ: 14980k, postfix:25, sys: 771 ---- dovecot restart complete ---- > 15:28:30: pop=3, imap=11, all=22, VSZ: 485k, postfix:25, sys: 282 > 15:29:00: pop=4, imap=65, all=83, VSZ: 2293k, postfix:26, sys: 344 > 15:29:31: pop=3, imap=91, all=111, VSZ: 3129k, postfix:27, sys: 373 It always seems to happen shortly after the number of dovecot processes goes beyond 500.

Returning custom autoexpunge for user's INBOX

I want to be able to have custom autoexpunge settings for different users. I have it working for various folders (draft, junk, trash), but I can't seem to get it working for the user's primary inbox. In my user_query (I'm using mysql), I'm returning entries like this in the userdb_import field: namespace/inbox/mailbox/autoexpunge=5d namespace/inbox/mailbox/Drafts/autoexpunge=5d namespace/inbox/mailbox/Junk/autoexpunge=5d namespace/inbox/mailbox/Trash/autoexpunge=5d And everything works fine for Drafts, Junk, and Trash, but not for the main inbox. The logs show: Debug: Unknown userdb setting: plugin/namespace/inbox/mailbox/autoexpunge=5d I've also tried variations, trying to get the namespace correct for the main inbox, but they all get the same "Unknown userdb setting" error: namespace/inbox/mailbox/autoexpunge=5d namespace/inbox/mailbox/inbox/autoexpunge=5d namespace/inbox/mailbox/Inbox/autoexpunge=5d namespace/inbox/mailbox/INBOX/autoexpunge=5d I suspect I'm just giving the wrong namespace for the primary inbox. What's the right way to do this? Tom

Hey guys, there seem to be a problem with wget and/or the unicode webserver. During the make process there are several files wich are download from the unicode server. I can access them manually but both curl and wget failing to get it. Are they any other mirrors or anyone else expiring this bug? Greetings

Unfortunately i have to continue this issue. During my last updates this problem is occured again.

Queries are not being sent to solr when search on server issued via imap client.
by ralph.jones＠modolingo.de 29 Feb '16

29 Feb '16

I traced the network communication with the solr server with tcpdump: sudo tcpdump -i any -A -vvv port 8080 I logged into the imap server via telnet (actually openssl) and issued the command ". search body <string>". About 20 results were returned within about half a second. Nothing was seen in tcpdump. When I issue "doveadm search box <string>", I can see the search string in the output of tcpdump and also in the solr logs. Solr seems to have been initialized correctly, in that when I issue a query via curl, I receive the correct results. I am using: dovecot 2.2.13 (debian jessie) libsolr-java 3.6.2+dfsg-5 relevant config: mail_plugins = fts fts_solr acl virtual plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ debug ... }

Dovecot sieve - How to check which username a mail is being delivered to?
by Yannik Sembritzki 27 Feb '16

27 Feb '16

Hi everyone, I am looking for a way to check which mailbox an email is being delivered to in a global sieve filter. After not being able to find some kind of variable that is populated by dovecot automatically, I tried to use the `Delivered-To` header. I tried a check like this: header :is "delivered-to" "<user(a)domain.org>" Unfortunately, this does not only match the first occurence of the header (which can be assumed is added by dovecot), but any occurence of this header in the email, which could be added due to previous deliveries and forwards, or just cause of malice. Is there any way to achieve this? Best regards, Yannik

Assertion crash: (idx * array->element_size < array->buffer->used)
by Joseph Tam 27 Feb '16

27 Feb '16

Log message: Traceback is hex gibberish: if symbolic traceback is needed, I'll recompile with "cc -g" and retest. Panic: file ../../../src/lib/array.h: line 219 (array_idx_i): assertion failed : (idx * array->element_size < array->buffer->used) (Similar to http://dovecot.org/pipermail/dovecot/2015-February/099771.html) IMAP command that provoked the crash: x1 FETCH 3 (BODY) Dovecot version: 2.2.19, Solaris10 (I don't think doveconf -n is relevant, but willing to provide if needed). It seems like a mailbox index issue. Removing, then recreating the indices gets rid of the crash. I saved these indices if it will help. Joseph Tam <jtam.home(a)gmail.com>

Different Quotas For Public Namespace

Dear All, are different quotas for public namespace folders possible? They're in the same namespace. If I got it right, the wiki says there's one quota per namespace only? - Chris

Block public namespace mail when quota exceeded
by Chris 26 Feb '16

26 Feb '16

Dear All, is it possible to temporarily reject mails, when quota of public namespace subfolder is exceeded? I'd check folder size with a cronjob. Dovecot is using a system user, so I guess blocking post and insert in ACL isn't a solution? I don't want to set the folder to read-only, that users can still delete mails. Thank you in advance. - Chris

Question: Directory hashing to support large domains | Dovecot & MySQL
by Altin Ukshini 26 Feb '16

26 Feb '16

Hello there, I have a postfix + dovecot + mysql installation in an ubuntu server. Virtual users and domains in a small mysql db that I manage via a web based mailadmin I wrote myself. The mysql db I'm talking about has a qmail structure that used to be managed by qmailadmin and worked with vpopmail. As for information, I cannot move to a different structure (exc postfixadmin/postfix) for many reasons, so I was forced to stick with it and configure postfix and dovecot to read that structure... If you may know, qmail (depends on the configuration) uses a directory hashing like /home/vpopmail/DOMAIN/P/7/USERNAME (something similar) in order to manage large domains, and this is handled by vpopmail. Please refer to these two links for details: - http://free.acrconsulting.co.uk/email/qmh.html - https://sourceforge.net/p/vpopmail/mailman/message/2710408/ I saw that dovecot uses something similar which I found in dovecot documentation : http://wiki2.dovecot.org/MailLocation#Directory_hashing Unfortunately, I cannot find more details, so I'd be thankful if you help me out with the following: By reading the documentation, I can tell that I can use the dir hashing variables in my dovecot configuration. But, in my case, I get the directory path from my mysql db via dovecot sql user_query - not from mail_location variable in 10-mail.conf Therefore if in case of a first received email for a user: dovecot checks in the db, gets the path and creates the maildir from the given path. In case the maildir column is empty, it fails, and it also fails to authenticate... So, can dovecot write to mysql? I would like to use directory hashing of dovecot, but from what I can find: If dovecot has mail_location variable set to do the dir hashing, it will not then go and add the created path in my mysql db. While if I try to implement something similar from my web gui application, I'd probably have to rewrite the algorithm that does this!? Can anyone help me figure out what's the best way to implement this? Thank you very much in advance for your help! Best, Altin Ukshini

[Feature Request] doveadm option to return number of messages acted upon
by Haravikk 26 Feb '16

26 Feb '16

So I have a script for handling my specific archive and expunge needs, but it’d be nice to be able to track how many messages are being affected. Currently I’m doing it by firing the same search queries into doveadm search and counting the lines of the result with wc -l, but that’s not a very pretty solution. While I’m mostly doing it out of interest on a personal server, I can’t imagine it’s a very scalable way to do it if you wanted to gather some kind of metrics for example. What I think would make sense would be for relevant doveadm commands such as move, expunge (probably purge too) and others I haven’t thought of to have a new option that, if enabled, will cause the command to output the number of messages affected as the final line of output (most of these commands don’t have any output anyway). A doveadm count command could also be a convenient, more efficient, alternative to doveadm search | wc -l.

Replication between two ISPCOnfig servers
by Otto Saayman 26 Feb '16

26 Feb '16

Hello I have set up two servers, one master and one slave, using ISPConfig. I have been using rsync to synchronise mails between the two machines, but this has some unstable results. I had a look at setting up replication: http://wiki.dovecot.org/Replication When I run the command, doveadm user '*', only two users are returned. So when I run this command: doveadm replicator replicate \* I get: 2 users updated I run this command: doveadm sync -u [e-mail address] tcp:[2nd/ slave dovecot server IP address] Here I can input any valid e-mail address in the ISPConfig MySQL database and it works. How do I tell the dovecote server to replicate all the users configured in the MySQL database it uses when it handles logins via POP/ IMAP, all of which is working fine? Is there a command I need to run at a set interval via cron to synchronise the two machines' mailboxes, which are identical in every way except the mails the users' mailboxes contain? OR Is there a way that I can instruct the two machines to keep each other's user mailbox contents "up to date"? The main idea is to have a hot backup of my "main" dovecot server and also to enable a lower mail priority for the second server so that mails are still received when the main server becomes busy, or is taken offline for some reason. Any help, or link to a HOWTO would be appreciated. -- Best Regards Otto Saayman

Checking index sanity
by Emmanuel Dreyfus 25 Feb '16

25 Feb '16

Hello We experienced corrupted dovecot indexes, probably caused by a server crash. This does not cause a lot of harm, just annoyance. For instance, LMTP raises an assertion during delivery, which causes mail to multiple recipients e-mail to remain in the queue if a single of them hits a corrupted index. The workaround for now is to detect the situation in the logs and to remove corrupted indexes when the problem arise. A better fix would be to sanity check all user's index on startup. Is there a command line tool to do this? -- Emmanuel Dreyfus manu(a)netbsd.org

SQLite driver and auth-worker credentials
by Lev Serebryakov 24 Feb '16

24 Feb '16

I want to use SQLite database as storage for auth and user databases. I've encountered two problems here: (1) There is no way to open SQLite database read-only (via sqlite3_open_v2() call with SQLITE_OPEN_READONLY flag). It looks bad. I don't need (and want) to give dovecot rights to write to this database. (2) I've created system group "hostingdb", added "dovecot" user to it and gives 660 rights to database file, but still "auth-worker" could not open database and complains to log file. Now I'm set "user = root" for auth-worker, but I don't like it! Why auth-worker doesn't belong to "hostingdb" group? -- // Black Lion AKA Lev Serebryakov

Script dovecot ACLs, Quota and doveadm
by Chris 24 Feb '16

24 Feb '16

Dear All, I'd like to set a) Quota for mailboxes in private and public namespace b) ACLs for both. What's the easiest way to do this? Do I have to call doveadm for every mailbox (private and public)? Is it required to provide a username to doveadm? Can I use the same user for all if it is defined in global ACLs? For Cyrus there are perl modules which have the same functions as cyradm. Is there something like this for dovecot? Are there any modules available? Haven't found anything in CPAN. - Chris

Streaming MOVE commands

Dear Dovecot devs, is streaming multiple MOVE commands by clients allowed? I am getting duplicated messages with the GNUS mail client, the interchange looks like this: *stream two moves to different folders* > 9019 UID MOVE 4062,4066,4068 "folder0" > 9020 UID MOVE 4063:4064,4067,4069:4072 "folder1" *the messages are copied* > * OK [COPYUID 1424475218 4062,4066,4068 376:378] Moved UIDs. > * OK [COPYUID 1424475231 4063:4064,4067,4069:4072 26:32] Moved UIDs. *however expunge fails to clean 4063, 4064, and 4067* > * VANISHED 4062,4066,4068:4072 thus 4063, 4064, and 4067 end both in inbox and folder1 producing duplicate messages (more details at [1]).

Automatically inferring %d on multi-domain virtual install ?
by Gabriel L. Somlo 24 Feb '16

24 Feb '16

Hi, I'm trying to allow domain-less logins for a multi-domain virtual IMAP server, and wondering if I can automatically infer the domain (value of variable %d) from the local IP (%l) or the hostname used by the client when connecting to my server. Let's say I have two host names: mail.foo.org (10.0.0.100) and mail.bar.com (10.0.0.200), with forward and reverse DNS configured to resolve A and PTR records in either direction. Let's also say I have 10.0.0.100 and 10.0.0.200 set up as secondaries on my server's loopback interface, and routing is set up to bring client traffic to me for both of those IP addresses. The relevant bits of my dovecot.conf are: ---%<------------------------------------------------------------------ mail_location = maildir:/var/lib/vmail/%d/%n passdb { driver = passwd-file args = /var/lib/vmail/etc/postfix/userdb } userdb { driver = static args = uid=dovenull gid=dovenull home=/var/lib/vmail/%d/%n } ---%<------------------------------------------------------------------ And my userdb passwd-file right now includes: ---%<------------------------------------------------------------------ user1@foo.org:{PLAIN}user1foo user2@foo.org:{PLAIN}user2foo user1@bar.com:{PLAIN}user1bar user2@bar.com:{PLAIN}user2bar ---%<------------------------------------------------------------------ Right now, user1(a)foo.org must configure their imap client like so: IMAP server: mail.foo.org username: user1(a)foo.org password: user1foo I would like to require this (and other) users to only have to set: IMAP server: mail.foo.org username: user1 password: ... and have dovecot somehow infer the "@foo.org" domain based on the fact that the connection was made to 10.0.0.100, which is mail.foo.org, and therefore the domain can *only* be "@foo.org". I could start out by splitting my user database into two files: userdb.foo.org ---%<------------------------------------------------------------------ user1:{PLAIN}user1foo user2:{PLAIN}user2foo ---%<------------------------------------------------------------------ userdb.bar.com ---%<------------------------------------------------------------------ user1:{PLAIN}user1bar user2:{PLAIN}user2bar ---%<------------------------------------------------------------------ ... then modify dovecot.conf's passdb setup like so: ---%<------------------------------------------------------------------ passdb { driver = passwd-file args = /var/lib/vmail/etc/postfix/userdb.%d } ---%<------------------------------------------------------------------ ... but how would I insure that %d is set to the proper value based on e.g. a reverse lookup of %l, which, in foo.org's case would be 10.0.0.100, and resolve to mail.foo.org, and *somehow* that would match %d == "@foo.org" ? Is this even possible in the first place, or am I just being too fussy about the aesthetics of my users' imap client config files ? :) :) Thanks much, --Gabriel
