Help with shared folder
by Gianluca Calloni 06 Oct '14

06 Oct '14

Hi dovecot guru.. I need some help configuring shared folder in my server.. This is the situation: DOVECOT 2.0.19 with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN This is the production server and sharing folder between user work.. But i need some explanation.. 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without share the main folder .INBOX? 2) Which is the best way (or best practice) to manage the dovecot-acl and dovecot-acl-list file?? Actually, i modifiy the dovecot-acl by hand (vi editor). but every time i modify it i need to restart the dovecot server to apply the configuration. And i need to reset the /var/run/dovecot/dict owner and group cause with dovecot restart the file go back in root:root owner - group Thank's in advance. Gianluca

v2.2.14.rc1 released
by Timo Sirainen 06 Oct '14

06 Oct '14

http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz.sig I've wanted to do this release for months now, but I keep being too busy all the time. This release fixes several important bugs and a lot of smaller ones. Because there are such a large number of changes I thought I'd make this release candidate release first and the final v2.2.14 early next week. I usually read through the Dovecot mailing list mails before making a new release to see if there are some (important) bugs reported, but I've been way too busy recently to read through everything. I still have over 250 unread mails and I don't think I'll have time to read them anytime soon. On the positive side the Dovecot company is now hiring more people. Especially having more Dovecot coders would reduce my work load and maybe allow me to go back to reading the Dovecot mailing list daily.. See: http://www.dovecot.fi/dovecot-is-hiring-software-engineer-helsinki/ (you can do this work anywhere - no need to live in Finland) http://www.dovecot.fi/dovecot-is-hiring-operations-and-support-engineer-hel… (this probably requires living in Finland) http://www.dovecot.fi/dovecot-is-hiring-technical-pre-sales-engineer-helsin… (probably no need to live in Finland) Here are some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

X-sieve-redirected-from
by Bob Miller 05 Oct '14

05 Oct '14

Hi, I am chasing a problem with sieve vacation messages. the sieve file looks like this: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["copy","vacation"]; # rule:[computerisms.ca] if anyof (address :contains "To" "bob.miller(a)ctfn.ca", address :contains "Cc" "bob.miller(a)ctfn.ca") { redirect :copy "bob(a)computerisms.ca"; vacation :days 66 :subject "autotest" "hello back"; } The mail is forwarded, but no vacation response is sent, and the mail is not forwarded. I find the lda error like this: _discarding_vacation_response_for_implicitly_delivered_message; _no_known_(envelope)_recipient_address_found_in_message_headers_ (recipient=<bob.miller(a)hostname.domain.tld>,_and_no_additional_ `:addresses'_are_specified) I am presuming this is the source of my problem. I am not sure why the domain is being modified to reflect the fqdn of the mail server host. When I look at the delivered mail, I find the following two headers: X-sieve-redirected-from: bob.miller(a)hostname.domain.tld Delivered-to: bob.miller(a)domain.tld I have been looking for a while now, and I can't figure out where it is picking up the hostname from. doveconf -a | grep hostname comes up empty. the hostname is not in any of the mta config files. Anyone got a hint? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot does not update maildirsize after expunge
by Király Balázs 04 Oct '14

04 Oct '14

Hello, At the first, sorry for my englishJ I have a problem with dovecot quota since i migrated from courier. Dovecot does not update the Maildirsize after expunge, and the user running out of his quota very quickly. I checked, the file is deleted from the filesystem. If i delete the Maildirsize file, dovecot regenerate it with the correct datas when a new mail arrive. Also tried to set mail_debug=yes, but it doesnt show anything in the log, when delete mails. Im using NFS as homedirs, i tried to turn off the releated options in configuration, but didnt help. Has anyone any idea how to fix this issue? Thank you!

Configure antispam plugin with private namespaces

When I use antispam plugin <http://wiki2.dovecot.org/Plugins/Antispam> with a folder that is outside a namespace, the plugin works great. But, if I configure it to watch a folder that is inside a namespace, the mailtrain backend does nothing. Does antispam plugin have support to namespaces? *This is my config:* namespace spam { type = private list = yes location = maildir:/var/mail.spam/%d/%n subscriptions = yes prefix = "SPAM." mailbox Filtrados { auto = subscribe } } plugin { antispam_backend = mailtrain antispam_verbose_debug = 1 antispam_debug_target = syslog # the above NOT works antispam_spam = SPAM.Filtrados # the above works #antispam_spam = Filtrados antispam_signature = X-VERTICAL-IP-Quarantine-ID antispam_mail_sendmail = /usr/local/bin/mail_spam.sh antispam_mail_spam = --spam antispam_mail_notspam = --notspam acl = vfile mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change save mailbox_create mail_log_fields = uid box msgid from subject size vsize quota = maildir:DefaultQuota quota_exceeded_message = O destinatario desta mensagem esta com a caixa postal cheia.

Thunderbird ignores some folders
by dovecot.pkoch＠dfgh.net 03 Oct '14

03 Oct '14

Dear readers we are using Dovecot 2.2.7 and all of our users are using Thunderbird as their mail client. Some of them additionally use their iPad/iPhone and a very few an Android Mail-Client. Now one user noticed that two of his mail folders disappeared. He first believed that he accidentally deleted those folders but then he realized that they are still visible from his iPad. I checked this users maildir and everything looks normal. Deleting the index-files made no difference: New index-files were created but those two folders are still invisable from Thunderbird. My main concern is to find the reason for this behaviour. Maybe folders of other users have disappeared and they have not yet noticed. A fresh installation of Thunderbird will most likely fix this single users problem, but I cannot do this for all of our users. So here's my question: How would I debug such a situation? Kind regards Peter Koch And here's our config file: # Dovecot configuration file default_process_limit = 2048 protocols = imap listen = * base_dir = /var/dovecot/ mail_location = maildir:/mail/%u:LAYOUT=fs ssl_cert = </etc/ssl/certs/naev+chain.crt ssl_key = </etc/ssl/private/naev.key ssl_ca = </etc/ssl/certs/naev-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier auth_ssl_username_from_cert = yes service imap-login { inet_listener imap { port = 0 } } service auth { client_limit = 4096 } service anvil { client_limit = 5000 } passdb { driver = checkpassword args = /usr/dovecot/bin/checkpassword } userdb { driver = passwd override_fields = home=/mail/%u } protocol imap { mail_max_userip_connections = 1000 }

LDA randomly failing to write email to disk
by Andy Dills 03 Oct '14

03 Oct '14

We're using 2.2.13 with pigeonhole 0.4.3, in a clustered environment (maildir on netapp, dual dovecot instances where each server is both a proxy and a backend). Every now and then (once a month per user, maybe?), users will see a blank email in their inbox. Investigating further, and we will see that the only information recorded in the maildir file for the message is the Return-Path, the Delivered-To, and the first Received line (the one generated by the local LDA via LMTP). For example, here is what I found in one such email today: Return-Path: <xxx(a)xecu.net> Delivered-To: <yyy(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail2.xecu.net (Dovecot) with LMTP idX86eBjgaI1RdyQAA3SxDBg for <yyy(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Everything past that is lost, as if the either the LDA on mail2 exited early or was never sent the information from the dovecot instance on mail5. Here is a little more detail from the header of the same email, different recipient (all other recipients received the email properly, only one failed to receive properly): Return-Path: <xxx(a)xecu.net> Delivered-To: <yyz(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail1.xecu.net (Dovecot) with LMTP id KPh8ItMXI1StBAAA/c3zFg for <yyz(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net by mail5.xecu.net (Dovecot) with LMTP id QsUBFoQZI1RjhgAAXyr1JQ ; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net (localhost [127.0.0.1]) by mail5.xecu.net (Postfix) with ESMTP id 30AAE323BB18; Wed, 24 Sep 2014 15:24:20 -0400 (EDT) ... This is what I see in the logs of mail2, which is where the failure happened: Sep 24 15:24:20 mail2 dovecot: lmtp(51549, yyy(a)xecu.net) X86eBjgaI1RdyQAA3SxDBg: sieve: msgid=unspecified: stored mail into mailbox 'INBOX' When I look at the logs of mail1, which is where the successful delivery happened: Sep 24 15:24:20 mail1 dovecot: lmtp(1197, yyz(a)xecu.net) KPh8ItMXI1StBAAA/c3zFg: sieve: msgid=<20140924192412.1435.qmail(a)xxx.xecu.net>: stored mail into mailbox 'INBOX' Nothing of note seems to be logged on mail5 (only a message from postfix, nothing from the proxy side of the lmtp). I do notice, when I check for the PID of 51549 in the logs, all of its other transactions seem to register with proper msgids and were delivered fine. Also, I notice plenty of other messages that have the msgid=unspecified error, but which were delivered with no problems and not truncated, so I'm suspecting what may be happening is that somehow the backend instance is not receiving the actual data portion, and only getting the envelope from proxy instance. How do I approach debugging this? It's very infrequent, but yet quite annoying. Seems to have started since we upgraded to 2.2.13 (from an older 2.1 build) earlier this year. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

GETMETADATA UTF8 encoding of folder names instead of UTF7

Hello, I have dovecot 2.2.13 instance and I found that (at least for polish language) folder names in GETMETADATA command response are encoded in UTF8. Shouldn't it be converted to UTF7?

home from SQL
by Ralf Hildebrandt 03 Oct '14

03 Oct '14

Currently I'm using user_query = SELECT 1000 AS uid, 1000 AS gid, '/srv/vmail/%2.256Hu/%Lu' AS home, ... so I'm hashing based on %u (basically). But in my SQL db I have a "unique_identifier" field, which never changes, even when the user is changing his/her email address (due to marriage or the like). What I'd really like to do is to use %u to find the value of the unique_identifier field, hash THAT value and use "AS home". But how? That way I can rename users without shuffling directories around the filesystem. -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Re: [Dovecot] quota using wrong limits in user shared mailboxes
by Bartłomiej Nogaś 03 Oct '14

03 Oct '14

Hi, I confirm this bug with LDAP userdb. The temporary workaround is to set quota ignore rule for Shared namespace or specific shared folder. This is obviously not secure workaround. Example: for a shared namespace: namespace ( .... prefix = Shared Folders/%%u/ ... } you have to set quota_rule4 = Shared Folders/*:ignore or quota_rule4 = Shared Folders/username/*:ignore - Bartlomiej Nogas

Hello, I'm attempting to install the listescape plugin so that IMAP users are able to include periods (.) and forward slashes (/) in IMAP directory names. I'm following the instructions at http://wiki2.dovecot.org/Plugins/Listescape , which imply that this can be accomplished by enabling the listescape plugin and using the dollar sign ($) as the separator. With regard to my dovecot configuration, first, I changed protocol imap { mail_plugins = quota imap_quota antispam } to protocol imap { mail_plugins = quota imap_quota antispam listescape namespace private { separator = $ inbox = yes } } When I start dovecot, I receive the following error: doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:102: namespace private {} has been replaced by namespace { type=private } Pretty straightforward; I made the required change to yield protocol imap { mail_plugins = quota imap_quota antispam listescape namespace { type = private separator = $ inbox = yes } } But now, when I attempt to start dovecot, I receive the following error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ Is it possible that the instructions at the Wiki 2 URL cited above are out-of-date? If I try to escape the $ with any other character (I'm just shooting in the dark regarding possible escape characters, as I cannot find definitive documentation that pertains to escaping $ in the dovecot configuration), I receive yet another error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long Ultimately, I have two questions: 1.) Is the nesting structure that I've employed correct? The Wiki 2 page is not clear with regard to the nesting; is it correct to put the "namespace" block inside the "protocol imap" block, as I demonstrated above? 2.) Is it possible to escape the dollar sign so that it can be used as the separator? Full "doveconf -n" output is included below.

auth with entire email addr instead of just username
by Cliff Hayes 02 Oct '14

02 Oct '14

I am trying to configure a new IMAP based mail server. I thought I had everything correct. I have dovecot logging turned up and see that dovecot is processing the entire email address as the username like this... Oct 2 14:52:20 servername dovecot: auth: Debug: pam(testuser(a)domain.com,1.2.3.4): lookup service=dovecot ... and of course pam is reporting that as an invalid user. Moments ago when all was mbox, authentication worked fine. I can see Thunderbird has the username correct (no domain). What is tacking on the domain and how do I fix? Thanks in advance.

two dovecot instances
by jjhoffart 02 Oct '14

02 Oct '14

Hello, I am currently trying to setup two invocations of dovecot to run on a debian based server. One for director and the other a stock debian instance. The issue I am having is when I go to start the director instance, I receive multiple errors telling me that the listening ports are already in use. I have change these ports in the 10-master.conf file but am still presented with the same errors when starting the second instance. Is this the only file in which the ports need to be changed (10-master.conf) or is there another file in which the ports need to be set?

Simply mysql quota check
by Alfredo Saldanha 02 Oct '14

02 Oct '14

Hi there, I'm setting up a new email server with Dovecot(2.2.9) and MySQL. My Dovecot configuration: #/etc/dovecot/conf.d/90-quota.conf service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = dovecot unix_listener quota-warning { user = vmail } } plugin { quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u@%d quota_warning2 = storage=80%% quota-warning 80 %u@%d args = /etc/dovecot/dovecot-sql.conf.ext } #/etc/dovecot/dovecot-sql.conf.ext password_query = \ SELECT username AS user, value AS password \ FROM mailboxes WHERE username = '%n@%d' user_query = \ SELECT username, domain, \ CONCAT('*:storage=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule \ FROM mailboxes, domains WHERE mailboxes.username = '%n@%d' \ AND domains.domain = '%d' My idea is when a message is delivered, the dovecot to check quota in the mysql according to the value received in the "user_query" but he does not. It shows a value of 2GB that I don't know where it gets. I execute a manual query in mysql to know the quota my test user and checked that are 5GB, but when I see the dovecot, it shows 2G. SELECT username, domain, CONCAT('*:bytes=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule FROM mailboxes, domains WHERE mailboxes.username = 'junix(a)domain.com' AND domains.domain = 'domain.com' +-------------------+----------------+--------------------+ | username | domain | userdb_quota_rule | +-------------------+----------------+--------------------+ | junix(a)domain.com | domain.com | *:bytes=5242880000 | +-------------------+----------------+--------------------+ $ sudo doveadm quota get -u junix Quota name Type Value Limit % User quota STORAGE 10 2097152 0 User quota MESSAGE 1 - How would the setting to simply verify the quota of users as userdb_quota_rule this query?

Master user and invalid credentials dovecot-2.2.13
by Götz Reinicke - IT Koordinator 30 Sep '14

30 Sep '14

Hi, I followed the docs from the dovecot wiki (http://wiki2.dovecot.org/Authentication/MasterUsers) and still have some problem: 1. uncommented "!include auth-ldap.conf.ext" in 10-auth.conf 2. htpasswd -b -c -s .... to create user/password for a masteruseruser 3. checked auth-master.conf.ext When I try to test the login, I always get an "invalid credentials" in the logs with auth_debug=yes set. dovecot can read /etc/dovecot/master-users The users are in ldap. The example wiki shows the passwords {SHA1}...., in my password file they are {SHA}.... The "master user" posting in september gave some clues what might be wrong, but did not help to solve my problem. Any suggestions are welcome! Thanks and regards.

No AUTH PLAIN with dovecot 2.0.19
by Michael Wechner 30 Sep '14

30 Sep '14

Hi I have installed the package dovecot-postfix on Ubuntu 12.04 LTS: dovecot --version: 2.0.19 postconf -d | grep version: 2.9.6 and receiving email works very fine, but relaying email does not work. I think the problem is that after STARTTLS the authentication is not being executed 250-AUTH PLAIN 250-AUTH=PLAIN which means using telnet returns telnet mx2.wyona.com 587 Trying 50.116.54.197... Connected to node3.wyona.com. Escape character is '^]'. 220 node3.members.linode.com ESMTP Postfix (Ubuntu) EHLO letscallitevil.com 250-node3.members.linode.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So far I have used dovecot version 1.2.9, which works very fine, but the configuration /etc/dovecot/dovecot.conf seems to be very different in the case of dovecot version 2.0.19. I have checked all kind of tutorials for several days now, like for example https://help.ubuntu.com/10.04/serverguide/postfix.html but nothing helped. Any pointers or help is very much appreciated. Thanks Michael

"doveadm backup/sync" are badly documented
by Jesus Cea 29 Sep '14

Most documents around there talk abour "dsync", but the modern way is "doveadm backup". This command is not documented in the wiki and there are a few details missing, like how to use it thru SSH. I am currently doing some tests about how to backup my mdbox. I can do tests in local using: $ doveadm backup -u jcea -m proveedores/dovecot mdbox:/tmp/aa/ This will "backup" this mailing list mailbox to "/tmp/aa". Good. Lets try thru SSH: $ doveadm backup -u jcea -m proveedores/dovecot ssh 127.0.0.1 dsync -u jcea mdbox:/tmp/aa/ jcea(a)127.0.0.1's password: Fatal: Invalid parameter: mdbox:/tmp/aa/ dsync-local(jcea): Error: read(remote) failed: EOF (version not received) How shoudl I do it?. $ doveadm backup -h backup: invalid option -- 'h' doveadm backup [-u <user>|-A] [-S <socket_path>] [-dfR] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] <dest> I can't find any explanation at all about the different parameters of "doveadm backup".

"doveadm backup/sync" don't follow message moving even with MDBOX
by Jesus Cea 29 Sep '14

29 Sep '14

Using mdbox as the storage backend, moving a message from a mailbox to another just update a reference. The message is not fisically moved on the disk. I would expect "dsync" to use this fact when source and destination are mdbox. But it doesn't. Anybody else can confirm?. Any plan to implement it?. Thanks!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

dsync full sync
by Atıf CEYLAN 29 Sep '14

29 Sep '14

Hi all, I have 2 question. First: I use dovecot (version 2.2.9) with mdbox mail format. When I run dsync tool with "mirror" or "backup" parameters my source and destination directory synchronize correctly but if I delete some messages in user mailbox, deleted messages does not synced to destination. For example : atif(a)domain.com path is /mail/domain.com/atif/ and its size is 1GB. after first running the "dsync -u atif(a)domain.com backup mdbox:/backup/domain.com/atif/" command, size of "/backup/domain.com/atif/" is 1GB I deleted 300mb messages in atif mailbox then /mail/domain.com/atif/ is decreased to 700MB and I launched dsync command again. But /backup/domain.com/atif/ is not decreased to 700Mb. My backup directory still 1GB . I tried dsync with "-f , backup, mirror" parameters. Second problem, the first time the backup atif's quota size is increasing to x2. before backup : atif(a)domain.com quota size 1GB after backup: atif(a)domain.com quota size 2GB so I must run "doveadm quota recalc" command. Why? What is correct usage of mdbox mail format and dsync tool? -- M.Atıf CEYLAN

dsync mirror does not maintain changes between mailboxes
by Alan McGinlay 28 Sep '14

28 Sep '14

Hi, running: dsync -D -v -o mail_fsync=never mirror -R -f -u user@domain imapc: Where "domain" is a cyrus imap server does not do what the documentation says it does, not even close. After the first run to an empty mailbox on the dovecot 2.2.13 server all the mails (1.1GB) seem to be correctly synced. I send a test email to the dovecot server and it shows up correctly. Second run of the above dsync command, first thing that happens is all mails are deleted from the dovecot mailbox (yet the storage used by output of "du -m" doesn't change) and the sync appears to happen again from scratch however the disk space increases again! Now up to about 2GB and another run will take it up a few hundred mb more! I have tried with multiple different mail storage formats, maildir++, mdbox sdbox, all show the same (except maildir which just complains that INBOX can't be deleted on the second dsync run). This is frustrating beyond belief, please please anyone who has any insight let me know, the dsync debug output is a little huge to sanitize and post to the list but i can send it individually if anyone has any ideas! I am ready to give up totally on dovecot but at the same time I just wish it would work! doveconf -n # 2.2.13 (6bb26098a45c): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-67-virtual x86_64 Ubuntu 14.04.1 LTS auth_debug = yes auth_master_user_separator = * default_vsz_limit = 512 M disable_plaintext_auth = yes imapc_features = rfc822.size imapc_host = oldmailhost.domain.com imapc_master_user = cyradmin imapc_password = xxxxxxxx imapc_user = %u mail_gid = vmail mail_home = /var/vmail/domains/%d/%1n/%n mail_location = sdbox:~/sdbox mail_plugins = zlib notify quota fts fts_solr mail_prefetch_count = 30 mail_uid = vmail mailbox_list_index = yes managesieve_sieve_capability = fileinto imapflags 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 = / } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ quota = dirsize:User quota quota_grace = 10%% quota_rule = *:storage=20G sieve = ~/.dovecot.sieve sieve_dir = /var/vmail/sieve/domain/%1d/%d/%1n/%n/ sieve_extensions = imapflags fileinto zlib_save = bz2 zlib_save_level = 5 } protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } 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 } vsz_limit = 512 M } service imap { process_limit = 1024 vsz_limit = 512 M } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = zlib notify quota fts fts_solr quota sieve } protocol imap { mail_plugins = zlib notify quota fts fts_solr imap_quota } protocol sieve { managesieve_implementation_string = Cyrus timsievd v2.2.13 }

Dovecot Sieve and Postfix header_checks Issue
by Klaipedaville on Google 27 Sep '14

27 Sep '14

Hello List, I tried to subscribe but it's taking forever for the confirmation email to arrive so I thought I would ask away by emailing directly. My apologies in advance should this question appear twice. It may seem real simple to experts but I cannot really figure it out. I'll try to be concise: Dovecot version is 2.1.7. Its dovecot –n is real short one and follows right after my question. I have my Postfix 2.9.6 properties set like this: header_checks = /etc/path/to/myfile. Then I have Dovecot Sieve also configured and working fine. Now the trouble is that these two cannot be combined together can they? Dovecot Sieve and Postfix's header_checks? If I turn off header_checks in Postfix then Dovecot Sieve is working fine. If I vise versa turn off Dovecot Sieve then Postfix's header-checks are also working fine. However, when I keep them both turned on it also works but only partially and in this case Dovecot Sieve never bounces back any rejected massages remotely, the bounce happens only locally. That is I can see it in my logs that it was rejected locally but the message is never sent back to the sender saying something like, "Spam is rejected here". Thus the reject turns into a silent discard without telling the sender anything at all. Any ideas, help, advices how do I fix that? Would be really grateful for any suggestions / assistance at all. Many thanks in advance! P.S. I would like to use both because Dovecot Sieve is a very powerful and great plugin that uses Spamassassin's added tags and headers based on which I create my rules. Postfix in its turn has a very neat feature of checking the headers via regexp but Postfix does not see / detect Spamassassin's added headers at all because I passed delivery and authentication (which is a way better than Postfix's) to dovecot deliver. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.6 ext4 auth_mechanisms = plain login cram-md5 scram-sha-1 auth_verbose = yes hostname = WindTalker info_log_path = /var/log/dovecot-sieve.log log_path = /var/log/dovecot-sieve-errors.log mail_location = maildir:/home/mvail/%d/%n 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 passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_default = /etc/dovecot/default.sieve sieve_dir = ~/sieve } pop3_uidl_format = %g postmaster_address = postmaster(a)example.com protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_ca = </etc/ssl/ca.crt ssl_cert = </etc/ssl//new.crt ssl_key = </etc/ssl/new.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { mail_debug = yes mail_plugins = sieve } Regards, Dennis.

Thanks for confirming what I suspected, Timo. The latter, if it is at all feasible, appears to be an "inside job" type of exploit, where the exploiter already has an account but can arbitrarily change their password. It's not as serious as the pre-login one, but worth addressing if the narrow circumstances of using post-login bash scripts apply. Joseph Tam <jtam.home(a)gmail.com>

Re: director
by Chris Lasater 26 Sep '14

26 Sep '14

The configuration and run/base_dir directories can be where ever you like. The locations Eduardo stated are the most appropriate for dovecot installed with an RPM. Mine were compiled and set in the home directory, so they are in a slightly different location. As long as you use the -c to point to the correct configuration file you should be good. For mine I kept my dovecot config file in the default location and put the director one elsewhere and created an alias, so that I can start the director by just typing director. This might make things easier for you to manage, then you can just stop it by running "doveadm -i <instance_name> stop" alias director="sudo -E PATH=${PATH} LD_LIBRARY_PATH=${LD_LIBRARY_PATH} /home/user/dovecot/sbin/dovecot -c /home/user/dovecot/etc/dovecot/director.conf" On 09/23/2014 05:00 PM, jjhoffart wrote: >> Thanks for the replies, >> I am still fairly new to dovecot and still learning.

The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot.

Backend is the same. >>> >>> In order to help more, provide us more details about your environment and doulbts. >>> >>> On 09/23/2014 03:57 PM, jjhoffart wrote: >>>> Hello, >>>> I am currently trying to setup a cluster of mail servers. I currently have two servers I am trying to cluster together. These servers will also have a shared NFS backend. I have read on the site that I will need to configure director since I am using NFS. I have read through all of the documentation on director but still need a little guidance to get things up and running. One of the questions I have is about the base_dir on the Multiple Invocations section of the wiki. It states that I will need to change the bas_dir to the new run directory, not sure what needs to happen here, can anyone help me out?

Namespace configuration over SQL

Hello! I had working setup, where namespace settings (including prefix) was queried over SQL. Now, after installing new Dovecot to new server (using same configuration), this is not working anymore.

Is dovecot vulnerable to the shellshock/CVE-2014-6271 exploit?
by Joseph Tam 26 Sep '14

26 Sep '14

I'm right now handling this beach-ball sized grenade, and trying to figure out which of our services need to be locked down right away. Since dovecot passes values via environment variables based on user input (e.g. username, password, mailbox?) to auxilliary executables (including possibly bash shell scripts), is dovecot vulnerable to this exploit? (This is not a fault of dovecot, but rather bash's inadequate handling of environment variables.) For example, injection of this sort 1 LOGIN (){x;}exploit-code whatever I guess auth_username_chars would mitigate this particular attempt (assuming it can work), but other values such as mailbox names could also be injected post authentication. Can someone with working knowlegde of dovecot's internals confirm/deny whether this is a something that needs to be addressed? Joseph Tam <jtam.home(a)gmail.com>

How to configure dovecot imap to listen on multiple ports?
by Rick Thomas 26 Sep '14

26 Sep '14

I need my dovecot imap server to listen on ports 143, 993, and also 30143 and 30993. What syntax do I use in (I presume) the /etc/dovecot/conf.d/10-master.conf file to do this? Thanks! Rick

Does dovecot work OK on *BSD?
by Steve Litt 26 Sep '14

26 Sep '14

Hi all, I have a dovecot server on my Debian Wheezy desktop computer. My days with Debian are limited, and I'm investigating several 'BSD's: OpenBSD FreeBSD PCBSD NetBSD DragonflyBSD etc Is there any reason Dovecot wouldn't work on any of those? Does anyone know if those OS's have packages for Dovecot, or do I need to compile it myself? Thanks, SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Confusing wording on the wiki
by Alan McGinlay 24 Sep '14

24 Sep '14

Hi, I am confused by the wording of this Wiki entry: sieve = ~/.dovecot.sieve The path to the user's main active Sieve script. When ManageSieve is used, this is a symbolic link pointing to the active script in the sieve_dir directory. Avoid placing the active Sieve script inside the sieve_dir directory. So this should be a link *to* the active script in the sieve_dir directory however the active script shouldn't actually be in that directory???? http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration Confused :S /A

Empty mailboxes
by Daniel Miller 24 Sep '14

24 Sep '14

This is driving me nuts. I need to rebuild a server - got a notification the main drive is failing, and it's been a year or two, so it's time. Got a new drive, fresh install of Ubuntu Tantric, started installing everything needed. Data stored on a RAID array - nicely available separate from the boot/operation drive. Did a fresh compile of Dovecot, copied over the configs from the old drive, mounted the RAID...and... Dovecot starts, authenticates users - and shows empty mailboxes. Nothing shown. Full panic - reboot on old drive. All mails present. Change back - no mail. Executing "doveadm user -u username" seems to give valid results. Mailbox location appears correct (using mdbox). I setup uid/gid the same - I thought it was a rights issue but everything looks correct. What can I do to try to find the stupid mistake I'm making? -- Daniel

quota recalc problem for big maildirs
by Dawid Stawiarski - nazwa.pl 24 Sep '14

24 Sep '14

hi, we use dovecot 2.2.13, and we've lately started using maildir quota (previously fs quota was used, right now it's "quota = maildir:User quota" changed from "quota = fs:User quota:user:inode_per_mail"). When the change was applied we didn't manually forced generating maildirsize files. So, when the first deliver happens (or the file grows larger then 5KB) it starts quota recalc. However for users with big maildirs, receiving email every couple of seconds, there are tens of delivery processes each doing its own recalc (as they open file for APPEND and there's no locking). What's even worse, after all the stats and getdents (it takes a lot of IO for 60GB account with 2M emails), deliver makes stat on 'new' dir and detects changes after which it unlinks freshly created maildirsize. So possibly this will never be finished as every process drops its own work. The same thing happened when we checked the native dovecot LMTP server (every connection has its own forked process - each running independently of the others). Is it a known unwanted "feature" of maildir quota (and we should use dict quota instead) or a bug that will be fixed? cheers, Dawid Stawiarski

Re: director
by Eduardo Ramos 23 Sep '14

23 Sep '14

The configuration use to be in /etc/dovecot, and the working dir is /var/run/dovecot. You should store your configuration file in the /etc/dovecot. The dovecot.conf file can be copied to dovecot-backend.conf and dovecot-director, for example, and you will use '-c' argument of dovecot binary to load on or another. If you do this, you will need create two separated working dir, that will be defined in base_dir on each configuration file.

This is a quick run down of my setup: 3 servers running iRedMail (this is a package that installs dovecot 2.1.7, postfix, and LDAP). All three servers share an NFS backend. The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot.

director
by jjhoffart 23 Sep '14

23 Sep '14

Hello, I am currently trying to setup a cluster of mail servers. I currently have two servers I am trying to cluster together. These servers will also have a shared NFS backend. I have read on the site that I will need to configure director since I am using NFS. I have read through all of the documentation on director but still need a little guidance to get things up and running. One of the questions I have is about the base_dir on the Multiple Invocations section of the wiki. It states that I will need to change the bas_dir to the new run directory, not sure what needs to happen here, can anyone help me out?

dsync error: Error: Can't delete mailbox INBOX: INBOX can't be deleted.

Hello, I'm aware of these two threads http://www.dovecot.org/pipermail/dovecot/2012-March/thread.html#134311 http://dovecot.org/pipermail/dovecot/2012-June/thread.html#136488 but unfortunately I wasn't successful with my dsync mailbox migration attempt despite the information I could find there. I'm using iRedMail setup for the dovecot server. I made sure that the dovecot mailbox for the mail import had been freshly created and untouched before I tried to run the following command.

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 23 Sep '14

23 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Announce: Plugin for iOS Push Email support
by Stefan Arentz 23 Sep '14

23 Sep '14

I’ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple’s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.

Re: [wishlist] testsuite for sieve scripts, libsievetest
by Phil Carmody 23 Sep '14

> BTW: It would be nice, if I could just 'git clone' dovecot. Hi, Thomas, I happily use Felipe Contreras' excellent git-hg bridge, as I am far happier in a GIT environment than an Hg one: https://github.com/felipec/git/wiki/git-remote-hg The workflow couldn't be much easier, in particular if you set up a few aliases for the common sequences of tasks. $ hg clone http://hg.dovecot.org/dovecot-2.2 $ git clone "hg::/home/phil/dovecot-2.2" dovecot-2.2-git $ cd dovecot-2.2-git $ git checkout -b hacking $ # work... $ cd ../dovecot-2.2 $ hg pull -u $ cd ../dovecot-2.2-git $ git checkout master $ git rebase master hacking $ # more work... (OK, my workflow includes pushing too ;-) ) Hope that helps. Cheers, Phil

dsync annoyances
by Alan McGinlay 23 Sep '14

23 Sep '14

Hi! Every time I run dsync for a user against an old Cyrus server, the users mailbox in Dovecot increases by several hundred MB, these are not new emails. So the first dsync run gets the whole mailbox and subsequent runs get a bunch of duplicates or what? doveadm purge clears them all out but why is dsync behaving like this? I didn't happen in previous versions (2.2.13)

[wishlist] testsuite for sieve scripts, libsievetest
by Thomas Koch 23 Sep '14

23 Sep '14

Hi, I'm writing a test suite with Haskell for my sieve script. - Just to learn Haskell. But it might become something usable. The test suite calls sieve-test and parses the output. So it would of course be much simpler for me if the output of sieve-test would be easier to parse and if I'd know what output to expect. And it would be nice, if there would be an easy way to embed libsievetest as a C library. I looked into the source and the sieve-test binary does quite a bit of setup. This might be a nice hacking project for a beginner... BTW: It would be nice, if I could just 'git clone' dovecot. Thank you for dovecot!

doveadm with multiple instances on same machine(s)
by Will Yardley 22 Sep '14

22 Sep '14

Couple questions about running doveadm with multiple instances... I have Dovecot 2.2.13 on RHEL6 running across 3 boxes, each with a director and main instance running. When I try to lookup something on the main instance (which is handling user auth) via its auth-userdb socket directly, I get an error: # doveadm auth lookup -a /var/run/dovecot-main/auth-userdb myuser doveadm(root): Error: passdb lookup failed for myuser: Configured passdbs don't support crentials lookups When I use the default lookup map, I just get the proxy settings that are configured in the director instance's authdb. # doveadm auth lookup myuser passdb: myuser user : myuser proxy : y nopassword: y In addition, "doveadm director map" can't map the username -I get the error: doveadm(root): Error: User listing returned failure doveadm(root): Error: user listing failed [then I get the whole list, but with <unknown> for each user] The director itself doesn't have the LDAP passdb that the main dovecot instance talks to, but I have, in the director config: service doveadm { inet_listener { port = 8889 } } director_doveadm_port = 8889 local 192.168.x.x/24 { doveadm_password = XXXXXX } doveadm_proxy_port = 8888 And in the main config: service doveadm { inet_listener { port = 8888 } } local 192.168.x.x/24 { doveadm_password = XXXXXXX ## same password as above }

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 22 Sep '14

22 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Authentication using AD : bug ?
by Nicolas Cauchie 22 Sep '14

22 Sep '14

Hello, I've setup a mail server (still in test) with Postfix and Dovecot, authentication made using Active Directory. I authenticate my test user in AD well in Dovecot. However, if I change this user's password in AD, the old password still works for authentication in Dovecot and the new is working too. Is there a time to make Dovecot don't "remember" the old password or is it a bug ? Restarting Dovecot don't solve the problem. Do you already heard about this ? Please tell me what conf files you maybe need. Thanks in advance Nicolas signature -----

Re: LDAP and dovecot
by dovecot＠outputservices.com 22 Sep '14

22 Sep '14

For the record. I compiled dovecot to use the openldap libraries my openldap server uses. My email server and ldap server are on two different machines. So I just copied over my ldap libraries and placed them in the correct place and then compiled dovecot. I saw this clue in a different web page. Something about Solaris ldap libraries being bad. CPPFLAGS=-I/usr/local/openldap/include \ > LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This now allows me to authenticate with my openldap server. I am NOW able to authenticate to my ldap server. So my final configuration is: dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } /dovecot/etc/dovecot/conf.d/ldap.settings hosts = ldap.outputservices.com tls = no auth_bind = yes ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com Thank you all.

X-DOVECOT capabilities
by Timo Sirainen 22 Sep '14

22 Sep '14

Dovecot has a few hidden features currenly, which I know some webmails have been hardcoded to use. Maybe it would be nice to have these available in a bit more globally usable way and advertise some kind of X-DOVECOT capability? I don't really like the idea of having a ton of separate X-DOVECOT-* capabilities. Maybe instead just have X-DOVECOT-1 for the current functionality and when more is added X-DOVECOT-2 etc? Then describe in Dovecot wiki page what they actually contain. Thoughts? The current list of features are at least: - STATUS (X-SIZE): Sum of all RFC822.SIZEs in a mailbox. (More efficient than FETCHing them.) - STATUS (X-GUID): Show mailbox's GUID. - SEARCH X-SAVEDBEFORE, X-SAVEDON, X-SAVEDSINCE: Search with message's saved-timestamp. - FETCH X-SAVEDATE: Fetch message's saved-timestamp. - SEARCH & FETCH X-GUID: Search/fetch message GUID - SEARCH X-MAILBOX, FETCH X-MAILBOX, FETCH X-REAL-UID: With virtual mailboxes search/fetch the mail's physical mailbox name and message UID. - X-CANCEL <tag>: Stop a (long-running) command, which once in a while goes back to the main loop. For example SEARCH or FETCH.

how to solve : Dovecot version mismatch: Master is v2.1.7, lmtp is v2.2.13
by Dave Myers 22 Sep '14

22 Sep '14

Hello again dovecot list ;) I've recently upgraded my dovecot version from 2.1.7 to 2.2.13. both versions where installed from source. I upgraded why attempting to get lmtp working. I ultimately just coped the executable lmtp to the location that dovecot was expecting it to be in. but then the above error appeared. However when I get the info from dovecot I get the following... $ dovecot -n # 2.2.13: /usr/local/etc/dovecot/dovecot.conf so there seems to be an issue somewhere. I should note that I had copied my previous /conf.d/ files and then copied them back after the update. I guess that I have missed a switch during the build, or need to modify a line in the config somewhere that tells what the version is, but that doesn't explain why the dovecot -n returns the correct info, but the error reports something different. I am considering inserting the version_ignore=yes config option, but where should I insert it ? Thanks in advance.

dovecot´s multiple quota roots
by Andreas Kasenides 22 Sep '14

22 Sep '14

I am trying to find out how Dovecot behaves when there are multiple quota roots. I could not find something authoritative on this. For example, on a nicely running server that used fs quota I now have in 90-quota.conf > plugin { > quota = fs:Mail Quota:user:mount=/Mail > quota2 = maildir:Mail User Quota > } When I do > > doveadm quota get -u atrige01 > Quota name Type Value Limit > % > Mail Quota STORAGE 80036 204800 > 39 > Mail User Quota STORAGE 79306 - > 0 > Mail User Quota MESSAGE 304 - > 0 Apparently both STORAGE quotas values are the same. The question is which of the two is being used by Dovecot. If I insert a limit on the maildir quota which of the two will be used? I am using Dovecot 2.2.12. thank you

Thank you all for your assistance. I was able to locate another web site that mentioned I needed to compile dovecot with my openldap libraries. I then compiled dovecot in the following manner: CPPFLAGS=-I/usr/local/openldap/include \ LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/tmp/tocevod --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This then included the openldap libraries. I tested access and now it works. ldd on /dovecot/libexec/dovecot/auth showed the openldap libraries. libdovecot.so.0 => /usr/local/tools/dovecot/lib/dovecot/libdovecot.so.0 libpam.so.1 => /usr/lib/libpam.so.1 libldap-2.4.so.2 => /usr/local/openldap/lib/libldap-2.4.so.2 libsasl.so.1 => /usr/lib/libsasl.so.1 libssl.so.0.9.7 => /usr/sfw/lib/libssl.so.0.9.7 libcrypto.so.0.9.7 => /usr/sfw/lib/libcrypto.so.0.9.7 liblber-2.4.so.2 => /usr/local/openldap/lib/liblber-2.4.so.2 libresolv.so.2 => /usr/lib/libresolv.so.2 libgen.so.1 => /usr/lib/libgen.so.1 librt.so.1 => /usr/lib/librt.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libsendfile.so.1 => /usr/lib/libsendfile.so.1 libc.so.1 => /usr/lib/libc.so.1 libgcc_s.so.1 => /usr/sfw/lib/libgcc_s.so.1 libcmd.so.1 => /usr/lib/libcmd.so.1 libmd.so.1 => /usr/lib/libmd.so.1 libaio.so.1 => /usr/lib/libaio.so.1 libmp.so.2 => /usr/lib/libmp.so.2 libscf.so.1 => /usr/lib/libscf.so.1 libdoor.so.1 => /usr/lib/libdoor.so.1 libuutil.so.1 => /usr/lib/libuutil.so.1 libssl_extra.so.0.9.7 => /usr/sfw/lib/libssl_extra.so.0.9.7 libcrypto_extra.so.0.9.7 => /usr/sfw/lib/libcrypto_extra.so.0.9.7 libm.so.2 => /usr/lib/libm.so.2 Thanks again.

I have an odd issue in that when I connect to my dovecot server from either a local or remote system I can't see my test emails (I have the impression that is is looking at the wrong location on disk). here are some details.... # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail/: mail_uid = 1002 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes when I connect (via openSSL from a remote system) openssl s_client -connect mail.exsportee.biz:993 CONNECTED(00000003) depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify error:num=18:self signed certificate verify return:1 depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify return:1 [.... security stuff removed....] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot ready. auth login "websales(a)exsportee.biz" "testPassword" auth OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in a list "" "*" * LIST (\HasNoChildren) "."

Support of unicode in then recipient names
by Александр Егоров 19 Sep '14

19 Sep '14

Hi Dovecot Community, We are using ltmp to deliver messages through postfix to dovecot. During testing we have found that dovecot does not understand recipient email address if it is composed from national symbols : e.g. ยจฆฟคฏข(a)xn--22cdfh1b8fsa.xn--22cdfh1b8fsa Question is are there any plans to either add native support for such email addresses or to translate it to punycode and then try to find such a recipient? -- Александр Егоров (Alexander Yegorov)

Syslog PID

Hi! How to write PIDs to syslog? Example: Sep 19 00:57:00 hostname dovecot: pop3-login: Login: user=< username(a)domainname.com >, method=PLAIN, rip=XXX.XXX.XXX.XXX, lip=XXX.XXX.XXX.XXX, mpid=14407, TLS, session=<6LYlcmYDAQC4reGs> Sep 19 00:57:00 hostname dovecot: pop3( username(a)domainname.com ): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Sep 19 00:57:09 hostname exim[14423]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front) Sep 19 00:57:09 hostname exim[14424]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front I need it because i write all logs to postgresql and analyze them with Adiscon LogAnalyzer. Perhaps, per-process logs entry with PID would be better.

unable to see mail when using telnet / open ssl
by Dave Myers 19 Sep '14

19 Sep '14

Dear dovecot list. I'm setting up my own VPS and working through getting mail to work. Here is my dovecot -n $dovecot -n maildir:%h/%d/%n/mail : layout=fs # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail: layout=fs mail_uid = 1002 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes I can successfully log into dovecot using telnet and open ssl from a remote terminal, so authentication and everything is working fine. From the above dovecot -n I asume that mails should be going to /var/mail/virtual/domain/user/mail However when I view this directory I can see a number of test mails that I have sent using echo "Hello me" | mail -s "Dovecot test" $USER (see http://wiki2.dovecot.org/FindMailLocation) Why am I not seeing them when I use telnet / openSSL to log in? All help is greately appreciated. -- Tel: + 33 6 50 14 39 34 email: david.myers.24j74(a)gmail.com Addres: 22 Rue de L'Eglise 77700 Coupvray. 77700 France

negative auth cache?
by Will Yardley 19 Sep '14

19 Sep '14

I am using Dovecot 2.2.13, which doesn't yet seem to have the $auth_cache_negative parameter. Should the negative cache value honor $auth_cache_ttl then? I had a problem where some of our ldap systems were reinitialized. Some users, presumably those who tried to login while their records were returning a failure, became unable to login after the records were once again returning normally. I currently have: auth_cache_size = 5 M auth_cache_ttl = 5 mins # Not yet implemented #auth_cache_negative = 2 mins yet the problem seemed to persist for more than an hour. Also, how can I flush the cache for a non-default instance's cache using doveadm -- "doveadm auth cache flush" doesn't seem to have an '-a' option AFAICT. # doveadm auth usage: doveadm [-Dv] [-f <formatter>] auth <command> [<args>] cache flush w

LDAP and dovecot
by dovecot＠outputservices.com 19 Sep '14

19 Sep '14

At my company I have users who are now becoming remote and using their mobile devices for email. I use Solaris 10 10/09 s10x_u8wos_08a X86 as an operating system and I now need a more secure email solution than the generic sendmail / imap solution. I want to use dovecot and postfix because I have read good reports on these products for ease of setup and use. I need to use both with SSL certificates and username / passwords for both receiving and sending emails. I am having difficulty getting dovecot to work with my ldap password solution. I have read all the documentation, there is a lot of it, and find it confusing. But I have tried very hard to get the solution to work. I have not compiled postfix because I want to use the dovecot authentication solution it mentions. Therefore I need to get dovecot to work first. I have dovecot 2.2.10 & postfix 2.11.1 with openldap 2.4.33. I have tested dovecot with /etc/passwd /etc/shadow password authentication and password flat files. Those work, but not what I need. I need to use ldap so the users only have to set one password. Below is the information I have. I have created self signed SSL certificates for testing purposes. We will get real SSL certificates once everything is operational. ********* I compiled dovecot with the following command: ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes ------------------------------------------- dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } ------------------------------------------- /dovecot/etc/dovecot/tests/ldap.settings hosts = ldap.outputservices.com tls = no ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com ------------------------------------------- If I use ldap for passwords: 2014-09-18 09:44:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:44:33 auth: Fatal: LDAP: Buggy LDAP library returned wrong fd: 1 2014-09-18 09:44:33 master: Error: service(auth): command startup failed, throttling for 2 secs 2014-09-18 09:44:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<> , rip=137.106.101.127, lip=137.106.76.215, TLS handshaking, session=<d1Nt3FgD1wCJamV/> 2014-09-18 09:44:48 master: Warning: Killed with signal 15 (by pid=18992 uid=0 code=kill) ------------------------------------------- If I use a flat file for passwords: 2014-09-18 09:42:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:43:05 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=16769, TLS, se ssion=<vAny1VgDywCJamV/> 2014-09-18 09:43:05 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:43:05 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:43:10 imap(dave): Info: Disconnected: Logged out in=223 out=1122 2014-09-18 09:43:22 master: Warning: Killed with signal 15 (by pid=17115 uid=0 code=kill) ------------------------------------------- If I use /etc/passwd /etc/shadow for passwords: 2014-09-18 09:39:56 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:40:14 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=13053, TLS, se ssion=<uaT5zFgDwACJamV/> 2014-09-18 09:40:14 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:40:14 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:41:01 imap(dave): Info: Disconnected: Logged out in=219 out=1118 2014-09-18 09:41:33 master: Warning: Killed with signal 15 (by pid=14765 uid=0 code=kill) ------------------------------------------- I am using openldap 2.4.33.

I want to stop solaris versions of sendmail and use dovecot & postfix. I am also a little confused on the mail_location setting. We use thunderbird as an email client and it sets the "local folders" just fine. But with imap it puts the Sent, Trash, Draft folders in the users "home" directory. With dovecot I have to put them in a different folder, I called it posta for now. It then makes them . Files. (.Sent, .Trash ?)

If you only want to dump a few auth cache entries, you can just authenticate with a bad password. When a different (and possibly correct password) is supplied, there will be a cache miss and the new credentials will be cached. echo "1 login someuser badpassword\n2 logout" | netcat --ssl your-imap-server:993 Joseph Tam <jtam.home(a)gmail.com>

migration from cyrus with dsync sieve problem

Exit status code 134; what is it, in the context of Dovecot Antispam plug-in?
by Ben Johnson 17 Sep '14

17 Sep '14

Hello! I just migrated from Ubuntu 12.04 LTS to 14.04 LTS and thereby from Dovecot 2.0.19 to 2.2.9. I've been using dovecot-antispam plugin with great success for the past year with 2.0.19, but after this migration, I've been seeing the exit status code 134 in the syslog when attempting to debug the Dovecot Antispam plugin not working after the migration. I have some debugging output in my pipe script; the output looks something like this: Copying message contents to temporary file for debugging purposes; file is: /tmp/sendmail-msg-7662.txt Checking if the command-line input argument string (--spam) contains the string "ham" or "spam" Mode is "SPAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-7662.txt"' Exit status was 134 Yet, I'm able to copy the above command and execute it manually, via the command-line, and it works (and by "works", I mean to say that the behavior is correct and exactly as expected; I receive the "Spam" email at the designated mailbox). Here's how I'm calling it when it works perfectly well (as "root"): # su -c '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-7460.txt"' vmail Any idea what status 134 might be or how to work around it?

replicator only starts for users who log in at least once
by Alan McGinlay 17 Sep '14

17 Sep '14

Hi! I recently setup a second with replication to the other. Both machines run ubuntu 12.04 with dovecot 2.2.13 (6bb26098a45c). All users mail accounts are currently synced manually to the first (mb1) using a dsync script, they are synchronised from a cyrus imap server. Users are still logging into the cyrus server. It appears that the only accounts that are replicated are ones who have logged into either of the dovecot servers at least once, is this how it is supposed to work? I was hoping to get full replication of all mail accounts before starting to move users into the new system. Thanks, Alan

Case sensitivity
by John Oliver 15 Sep '14

15 Sep '14

I think I've answered my last question by changing mail_location But I'm still getting duplicate mailboxes: [joliver@localhost ~]$ sudo ls -l /var/vmail/ total 8 drwx------. 3 vmail vmail 4096 Sep 11 10:30 testuser1 drwx------. 3 vmail vmail 4096 Sep 11 10:36 testUser1 The cn for my user is 'testUser1', and that's where postfix writes mail. But dovecot wants to use 'testuser1', even if I log in as 'testUser1' I suppose one answer may be to try to get postfix to always use lower-case, but in case that can't happen, how can I get dovecot to ignore case when looking for mailboxes? -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Per-folder (per-mailbox) message expiration with control from client side — is it possible?
by Lev Serebryakov 15 Sep '14

15 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I'm migrating from «old skool» solution with one mail client (MUA) on one computer, which retrieves mail via POP3, sorts it and manages it locally to installation when there are several MUAs on different devices, accessing mail via IMAP4, and all sorting and management should be server-side. Sorting is “easy”: sieve. Here are some nuisance (like, if I want to rename folder/mailbox I need to edit script manually. BTW, it looks like that such thing could be done automagically, as language is very simple and find all references to mailboxes is not too hard task), but it works. But is here good solution for expiration? I have abut 50 folders (mailboxes) and rules are very different for them. They are mostly time-based (like "last 30 days"), but some folders are count-limited ("last 2000 messages") and some folders should have time limit but non-read messages could not be deleted at all. Ok, Thunderbird almost could do it (it doesn't have “don't remove unread messages” option), but I don't want to have any meaningful configuration in MUAs, as each of it could be non-active for long time. Only thing I could find about expiration in dovecot documentation is "doveadm expunge" and helper "Expire" plugin, but it looks like very low-level solution for admins, it could not be managed from client side without direct ssh access to server and it is, in general, very inconvenient. Is here any better solution, maybe, 3rd party one? - -- // Black Lion AKA Lev Serebryakov -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUFf2BXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRGOTZEMUNBMEI1RjQzMThCNjc0QjMzMEFF QUIwM0M1OEJGREM0NzhGAAoJEOqwPFi/3EePphIQAJUlYIFgXWBcWcrejcbOFgYf op+g35YF4wfwboPkgb/mKk46V3lcjmQImcHir2fci0SCsSSfARcU1a8y4iaeSkPU l949PaMYD8stfukfCbXjoY5pD5FIpj1Os7dDtgdoygp0tfsA4mDg1O0exZoduR9s q4NNPlsnlKOjX2KMOdcWI2AR8/xiFi4zvDTB/vibQPMy8kXVB8ld4Mk0BF1TUyOv 80KKOKzFDxQeLzvoEiNm6FDAqYGEYmpECUaFGXyKG1a7wslhEmEeShJUH5lsj3Oz niMxoO/KTEW0U9QucHQogFJzrcsKkJiOByjqQovWKgZziJll38lCN0O1murMmRBC bDLmN9t53JC7Ef88AbKsaFeULy/AxriohdGU6ePb8j/4W9KlERSJyvgxFkcMxHTg 9mSPiYAHaPr+Ycrzs9SOqhki5b6tI8Q39W/etRorb2us9FS1JE7ib4XLk5ufiUje XOLc4TACUh1qnd/5UUgcIuUrg/akSJgJLZoXg36LqUF/1OeMJHec4RMJresvewAZ RwseWHH/KpD7KxOWlO2Zw1ceHlVFDLWOO/4KWoy/XwZ66fQxEAkLO8ZVyeKMh5Nh dYL+yLQKZdgNWAjalK4lFmwz3u/9jNITwtP5GYLbYnP28EcbDfiN/w9oKGOI8fsD ulD+ca3vx29qdmGGYcKt =9+bG -----END PGP SIGNATURE-----

sieve: is it possible to filter ALL mailing lists (with header List-Id) to their folders with ONE rule?
by Lev Serebryakov 15 Sep '14

15 Sep '14

Hello, Dovecot. Is it possible to write one rule in sieve, which will: (1) Trigger on any message with "List-Id" header AND (2) Put this message to folder with name build from content of "List-Id" header, in such way, that message with List-Id List-Id: This is decription of list <list-name.host.org> will be put into folder "org.host.list-name" where "." is namespace separator (so, such folders will be shown as hierarchy in mail client)? I don't want to write ~50 rules by hands and add new ones from time to time. I'm speaking about dovecot/pigeonhole sieve implementation, of course. All examples on net shows only manual one-rule-per-list approach :( -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

Migration - Getting it right the first time.
by Dan Carroll 15 Sep '14

15 Sep '14

Hello All, I’m currently in the process of migrating a very old imap installation to a new server. I think I have everything in place now but I’ve not yet written the procedure on how to do it. The outline will be as follows: put MTA-OLD into store mode where it holds the incoming emails for an indefinite period. Copy all IMAP data across to the new server. Process the IMAP data, converting it from courier to dovecot. put MTA-OLD into forward mode, sending all mail to MTA-NEW Adjust MX records accordingly so MTA-OLD is no longer used. The “process” part is where I need to take some care. I am aware of the migration tool available for moving the data, but I’m not confidant that my courier databases are in a healthy state. Does anyone have any idea how I can verify that this is the case? I’m happy to do it either before, or after the migration to dovecot, but I’d probably prefer to do it beforehand on the old server. The biggest thing I am concerned about is losing the order of mail messages. It’s not always enough to trust the “received date” for sorting mail, I’d rather my imap clients trust the imap server to send them the correct order. A second question. Is there a possibility to make the MTA switch, and migrate the messages across in an orderly fashion at a later date? Again, I’d like to ensure that older migrated messages appear further down the “order” than new messages coming into the MTA. Lastly, thanks for an awesome piece of software. My limited experience so far has been refreshing! -Dan

Dovecot HA
by Hoggins! 12 Sep '14

12 Sep '14

Hello everyone, Following my previous message about replication (I'm still stuck), I was wondering in a more general way how to achieve high availability with Dovecot, and how to store the mail data. Do you have some thoughts about this ? Maybe one or two links leading to people who already have ideas or experience ? I don't host a big e-mail service, nor have a lot of clients connecting. I just need to ensure that data is always available, from the storage to the actual service. Thanks in advance.

charset-specific searches, and continuation lines
by Eric Abrahamsen 12 Sep '14

12 Sep '14

Hi there, I'm looking into improving IMAP search support for the Gnus Emacs mail client, and trying to add the ability to search non-ascii characters. So far as I know, I start this invocation with something like: . UID SEARCH CHARSET UTF-8 TEXT {NNN} Where NNN is the number of bytes in my search string. Dovecot then responds with: + OK So... what do I do then? I don't actually know what the next statement is, to provide the actual search string itself. Googling has proved unhelpful, as most of the examples online don't actually show this "+ OK" response. Can someone just briefly outline what's meant to happen next? I've tried including the search string immediately after the byte-size, separated by various combinations of \n\r, but that always gives me a "Missing LF after literal size" error. I'm using the Archlinux dovecot package, which reports version 2.2.13-1. Thanks! Eric

Problem with virtual folders
by Urban Loesch 11 Sep '14

11 Sep '14

Hi, I'm trying to activate some virtual folders on a new installed dovecot server. My plan is to have two virtual folders like "All" and perhaps "Unseen", like Gmail style for the first step. - All: lists me all messages in the users mailbox - Unseen: all unseen messages in the users mailbox I'm using dovecot EE Release: ii dovecot-ee-core 1:2.2.13.8-1 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-imapd 1:2.2.13.8-1 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-lmtpd 1:2.2.13.8-1 amd64 secure LMTP server for Dovecot ii dovecot-ee-managesieved 0.4.3-1 amd64 secure ManageSieve server for Dovecot ii dovecot-ee-mysql 1:2.2.13.8-1 amd64 MySQL support for Dovecot ii dovecot-ee-sieve 0.4.3-1 amd64 sieve filters support for Dovecot But I can't get it to work. I can see the virtual folders in my Thunderbird, but the folders are empty and can't find any errors in mail log. I also tried it with "mail_debug = yes".

I copied the configuration from this server. The only three differences between the two servers are: - Server version is different. - The prefix of the default namespace on the new server is "prefix = INBOX/" and not "prefix =" - Mail storage and index files are seperated in different folders on the new server. Here are the relveant namespace configuraiton from the server where it ist working fine: ... namespace { list = children location = mdbox:/home/vmail/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=~/virtual prefix = [rolmail]/ separator = / subscriptions = yes type = private } 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 = separator = / type = private } ... Have you any hint for me how I can fix my problem. Thanks and regards Urban Loesch

minimal configuration for lucene fts
by Eric Abrahamsen 11 Sep '14

11 Sep '14

Hi, I'm using dovecot (version 2.2.13 on archlinux) in the simplest, no-brainer way possible. It sits between mbsync, which I use to fetch mail from servers, and Gnus, my MUA. Both mbsync and Gnus connect to dovecot with an invocation like this: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/ea/ I have three different mail accounts, all that changes is the final directory on the mail_location path above. I haven't touched anything else: there's no running daemon, no configuration, no user database, no PAM, no nothing. Now I'm trying to set up text searching via lucene, but all the examples I've seen online assume a full running daemon and user accounts. I tried to fake it by running: doveadm index -u eric@localhost -q INBOX -o mail_location-maildir:/home/eric/.mail/ea but it was clearly expecting a user database. Is there any way to create text indexes for my three different accounts, in their respective directories, without fully setting up a running dovecot? I'll do that if I have to, but my current setup works great, and is very simple, and I'd like to keep it simple if I can. Thanks! Eric

Just a wild-ass guess, but shouldn't "master_user=%u" be something like "master_user=muser" where "muser" is the master user as defined in your master password file?

outlook 2013
by Bob Miller 10 Sep '14

10 Sep '14

I am trying really hard to wrap my head around why people insist on using this program... Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program. recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too. On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook. I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant. The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order. Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot replication
by Hoggins! 10 Sep '14

10 Sep '14

Hello list, I'm trying to achieve very simple replication, but I'm not sure if I'm starting the good way. I have two Dovecot servers that use the same GlusterFS storage. Of course, the indexes get corrupted eventually, even if I apply an "NFS-like" configuration. So I'd like to synchronize my two servers with each other. I'm trying to follow this page : http://wiki2.dovecot.org/Replication, but I have to admit that it's not really self-explanatory. I got several errors, so I decided to start fresh, and that is why I'm not giving you any configuration, but I prefer asking if I have the prerequisites. The page states that my userdb should have "user listing", and that you can check it by issuing `doveadm user '*'`. But I don't know what it's supposed to produce, apart from my userlist (my userdb is the system passwd file). As my servers are located on the same private LAN, I decided I would not go with the SSH replication solution, but with the simple mutual TCP connection... Maybe this is a wrong start. Any help will be appreciated. Thanks in advance !

dovecot 2.2.13: LMTP delivery with multiple recipients incorrectly mixes users
by Arkadiusz Miśkiewicz 10 Sep '14

10 Sep '14

Hi. I'm using exim that delivers email over LMTP to dovecot 2.2.13. I noticed that dovecot LMTP service is sometimes (reare but repeats) mixing users. Example below. There is one mail (msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>) that is going to be delivered to multiple local recipients. Some recipients are delivered properly: Sep 1 05:40:33 host dovecot: lmtp(3176): Connect from local Sep 1 05:40:34 host dovecot: lmtp(3176, gbuser1): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, jpuser2): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, rkuser3): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, gbruser4): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, pbauser5): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, mwauser6): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, mdyuser7): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX but some are not: Sep 1 05:40:34 host dovecot: lmtp(3176, lkrzyuser8): Error: lstat(/var/lib/dovecot/control/gbuser1/.INBOX/dovecot-uidlist.lock) failed: Permission denied Sep 1 05:40:34 host dovecot: lmtp(3176, lkrzyuser8): Error: file_dotlock_create(/var/lib/dovecot/control/gbuser1/.INBOX/dovecot-uidlist) failed: Permission denied (euid=28371(<unknown>) egid=17373(<unknown>) missing +x perm: /var/lib/dovecot/control/gbuser1, dir owned by 67593:17373 mode=0700) Notice it was trying to deliver to user "lkrzyuser8" but it tries to access some other user files (dovecot-uidlist). euid=28371 is indeed "lkrzyuser8" but why it tries to access "gbuser1" files?

Replication problem
by Ve (HOME) 10 Sep '14

10 Sep '14

Hi, I'm using mdbox and replication. Due to configuration error synchronization was not able to be done last week. Since then the problem has been corrected but synchronisation for some mailbox always failed in I/O stalled timeout for 600 seconds. The link between the two servers is quite slow and multiple sync are done in parallel leading to congested link. I can't replicate with rsync as change in the mdbox has been done on the two servers to get back to a working state. What do you think could be done to resynchronized the two dovecot server. Another question is what is this timeout ? Timeout of communication i.e no data received during 600 seconds ( to me that looks unlikely ) or 600 seconds for doing the full sync or 600 seconds for one mail sync. Thanks for any help. Regards, Vincent

preserving flags for shared mailbox when migrating from cyrus to dovecot
by Jogi Hofmüller 10 Sep '14

10 Sep '14

Dear all, Despite all the progress we are making in our attempt to make the migration as smooth and transparent for our users there are still some important unsolved issues. One thing that I can't figure out is how to preserve a user's flags that s/he has for mail in a shared mailbox. So far we tried 'doveadm backup -R' as well as the cyrus2dovecot script from here [1]. Both work well for individual mailboxes but do not migrate subscriptions for shared mailboxes and -- more importantly -- flags for mail in a shared mailbox. Reconstructing subscriptions is quite easy but I have no clue on how to reconstruct a user's flags. Any hint is greatly appreciated!

master user in ldap?
by Francesco 10 Sep '14

10 Sep '14

Hello everyone, i was wondering if it was possible to add master user criteria in ldap backends. the idea is that the users, members of a specific group, should be able to login with their own credentials on behalf of other users. i've tried setting it up like this: hosts = localhost dn = CN=ldapuser,OU=someldapou,DC=domain,DC=tld dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=domain,DC=tld user_attrs = sAMAccountName=home=/var/vmail/% $,skip=found,maxStorage=quota_rule=*:storage=% $M,quota_rule2=Trash:storage=+100M user_filter = (&(ObjectClass=person)(sAMAccountName=% u)(memberOf=CN=Domain Admins,CN=Users,DC=domain,DC=tld)) then i added a passdb as follows passdb { driver = ldap master = yes args = /etc/dovecot/dovecot-ldap-masteruser.conf.ext } and of course the separator. but when i try to login with realuser*userinadministratorsgroup passwordofuserinadministratorsgroup i get authentication failed. am i missing something? is it even possible to accomplish such thing? because i didn't see any example in the wiki, only plain passdb and sql. thanks in advance Francesco

Escape comma in the LDAP passdb subquery configuration
by Francesco Fiore 10 Sep '14

10 Sep '14

Hi I have to configure the LDAP passdb to execute a subquery defining dinamically the new DN to use. For example: pass_attrs = @mail=mail=%{login_user},dc=%{login_domain},dc=example,dc=com,\ =proxy=y,\ =host=%{ldap:mailHost@mail} In the previous example, the problem is the use of "," for DN representation, which is also the separator for the attribute template in the pass_attr parameter value. I tried to escape it with '\' or '%' but it doesn't work. Dovecot version is 2.2.13. How can I resolve this issue? Thanks in advance

ACL with Public Namespace
by Bruno Galindro da Costa 09 Sep '14

09 Sep '14

I've configured a namespace like this: namespace avisos { type = public list = yes location = maildir:/var/mail.avisos:INDEXPVT=~/Maildir/avisos subscriptions = yes prefix = "AVISOS." mailbox DIVULGA { auto = subscribe } } This is the namespace representation in filesystem: root@imap:~# ls -lha /var/mail.avisos/ total 44K drwxr-xr-x 7 vmail mail 4,0K Set 9 18:21 . drwxr-xr-x 16 root root 4,0K Set 9 17:08 .. drwxr-xr-x 5 vmail mail 4,0K Set 9 16:49 .DIVULGA -rw-r--r-- 1 root root 17 Set 9 18:21 dovecot-acl -rw-r--r-- 1 vmail mail 0 Set 9 18:11 dovecot-acl-list -rw-r--r-- 1 vmail mail 360 Set 9 18:11 dovecot.mailbox.log -rw-r--r-- 1 vmail mail 8 Set 9 18:02 dovecot-uidvalidity -r--r--r-- 1 vmail mail 0 Set 9 14:57 dovecot-uidvalidity.540f3f88 -rw-r--r-- 1 vmail mail 249 Set 9 18:11 subscriptions This is the content of dovecot-acl file located at namespace's root level: root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rs After reload dovecot service, it trows this error message in log: Sep 9 18:14:13 imap dovecot: imap(user@mydomain): Error: Failed to autocreate mailbox AVISOS.DIVULGA: Permission denied So, I've changed the dovecot-acl file to this one and the problem was solved. root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rsk But that change created another problem: dovecot-acl file is copied into AVISOS.DIVULGA. So, the user can create a maildir inside it. This behaviour is bad because "invalid" maildirs are created under the filesystem. My intention is to don't permit the user to create any maildir inside any location of that namespace. But, I want to make possible to the administrator to edit the dovecot.conf, insert a new mailbox into namespace avisos and reload dovecot service to create new maildirs automatically. How can I solve this problem? -- Att. Bruno Galindro da Costa

Dovecot + Postfix postmulti SASL
by Nerijus Kislauskas 09 Sep '14

09 Sep '14

Hello, Our Postfix setup uses multi-instance feature. I would like to enable dovecot SASL mechanisms in postfix. Open two unix sockets is not a problem for us: service auth { unix_listener /var/spool/postfix-instance1/private/auth { mode = 0660 user = postfix group = postfix } unix_listener /var/spool/postfix-instance2/private/auth { mode = 0660 user = postfix group = postfix } } Lets assume, that postfix-instance1 uses LDAP1, and postfix-instance2 uses LDAP2. How can I use different userdb and passdb databases for those sockets? -- Sincerely, Nerijus Kislauskas

Panic/backtrace in dovecot 2.2.13
by Ed W 07 Sep '14

07 Sep '14

Hi I'm running into regular problems with dovecot choking on "corrupted" index files. The main problem is that it doesn't sort itself out and recover. This message below is repeated regularly in the log files (until I delete the index files) I *think* the trigger to get into this situation might be a files being delivered with incorrect S= values in the filename? Which is to say I am using maildrop to deliver messages and occasionally maildrop seems to write files with incorrect S= names (anyone know why or how to fix it?). The error logged regarding incorrect S= values is obviously completely different, but I speculate that it could be the earlier cause that gets the index file out of shape as shown in the problem here Thanks for any help?

lmtp memory usage problem - Fatal: pool_system_realloc(268435456): Out of memory
by Arkadiusz Miśkiewicz 05 Sep '14

05 Sep '14

Hi. In my setup exim delivers mails to dovecot using LMTP. In one LMTP session exim can deliver up to 200 recipients (batch_max set to that value). Now the problem is that sometimes 256MB is not enoug for dovecot lmtp to handle incoming emails. My questions: - how big memory limit should be for lmtp? I was thinking that lmtp (more or less) simply reads from one descriptor and writes to file, then does rename() (maildir used here) and that's all. That shouldn't require big number of memory. So how to determine correct memory limit and what affects this limit? - is number of recipients in one LMTP session important here? Not sure, maybe dovecot stores email in memory first and then writes to the user maildirs? Setting (batch) limit to 1 could reduce memory usage then (since no need to store anything in memory) ? Thanks, Log: Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: pool_system_realloc(268435456): Out of memory Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x682a0) [0x7fe327e632a0] -> /usr/lib64/dovecot/libd ovecot.so.0(+0x6837e) [0x7fe327e6337e] -> /usr/lib64/dovecot/libdovecot.so.0(i_error+0) [0x7fe327e1dbf8] -> /usr/lib64/dovecot/libdovecot.so.0(+0x7d6a3) [0x7fe327e786a3] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_grow_buffer+0x8f) [0x7fe327e6c4cf] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_try_alloc+0x82) [0x7fe327e6c592] -> /usr/lib6 4/dovecot/libdovecot.so.0(+0x73b9b) [0x7fe327e6eb9b] -> /usr/lib64/dovecot/libdovecot.so.0(+0x73c36) [0x7fe327e6ec36] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x 53) [0x7fe327e6bad3] -> /usr/lib64/dovecot/libdovecot.so.0(+0x77391) [0x7fe327e72391] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x53) [0x7fe327e6bad3] -> /usr/lib 64/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7fe327e6c2fd] -> /usr/lib64/dovecot/libdovecot.so.0(io_stream_copy+0x7f) [0x7fe327e7cacf] -> /usr/lib64/dovecot/libdo vecot.so.0(+0x83310) [0x7fe327e7e310] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_send_istream+0x4d) [0x7fe327e7c92d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maild ir_save_continue+0x5a) [0x7fe32811b14a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0x88) [0x7fe328145328] -> /usr/lib64/dovecot/libdovecot-storage.so.0 (maildir_copy+0x42) [0x7fe3281179c2] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0xb52b) [0x7fe32764352b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_cop y+0x6d) [0x7fe32814d29d] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver_save+0x185) [0x7fe3283f1765] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver+0xeb) [0 x7fe3283f1b6b] -> dovecot/lmtp() [0x405d80] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x3f) [0x7fe327e7398f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handl er_run_internal+0xd7) [0x7fe327e74897] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fe327e739f9] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x3 8) [0x7fe327e73a78] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fe327e22ca3] Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: master: service(lmtp): child 21383 returned error 83 (Out of memory (service lmtp { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) -- Arkadiusz Miśkiewicz, arekm / maven.pl

stemmer or no-stemmer..
by Akash 05 Sep '14

05 Sep '14

Hi, In the documentation of FTS lucene, I need little more clarification about this section: -------------------------------------------------- --with-lucene --with-stemmer The second switch is only required if you have compiled libstemmer yourself or if it's included in the CLucene you are using. -------------------------------------------------- I am totally unsure but as I understand, on Debian testing, the stemmer support for libclucene comes as part of libclucene-contribs1 package (which isn't a required dependency and doesn't get installed if I install dovecot from repos). Please correct me if I am wrong. When I install dovecot-lucene from repos, libclucene-core1 and libstemmer install with it (but no libclucene-contribs1). Does that mean dovecot search has stemmer support? Now I am compiling dovecot and libclucene for Debian stable (which doesn't have latest libs in repos). If I don't compile the contribs part in clucene package but compile dovecot with --with-stemmer, do I get the stemmer support? If I totally opt of this stemmer thing, do I lose anything on search performance? And when you have a no_snowball option, what is the need of libstemmer altogether? Please help me through these confusions.. -Regards, Akash

Migrating from 2.0.x to 2.2
by Jens Dueholm Christensen 05 Sep '14

05 Sep '14

Hi I'm about to migrate a setup with <20 IMAP (but with a few million mails in all) accounts that belong to the same system-user on an older machine running Dovecot 2.0.13 to a new machine running Dovecot 2.2.13 (or possibly newer..). Mails are stored in Maildirs with no special or advanced features (like alternate storage etc etc). Filesystems are prepared for the expected amount of inodes required, and for the time beeing a change to mdbox is seen as an added complexity. One requirement of the migration is that messageID is not changed - mails are referenced by other systems that expect to find individual mails by the ID. Since dsync is incompatible between 2.0<->2.1<->2.2 what is the best way to perform this migration? I was hoping of rsync'ing all Maildirs from the old machine to the new one (including indexes etc etc) and power up Dovecot 2.2.x and see what happens, but is that possible or is there another (and better) way short of installing 2.0.x on the new machine, rsync everything and then upgrade to 2.2.x? Regards, Jens Dueholm Christensen

Hi, I want to profile runtime performance of imap and pop3 processes. There processes are forked by dovecot master process. I am wondering if there is a way I can profile these processes with valgrind. I tried "service = /bin/valgrind /bin/imap" but this did not work. Thanks,

Hi All, I have a problem with SASL authentification from postfix when more than 10 mails is sent from the same user simultaneously Postfix abort connection ( Connection lost to authentication server ).

Trying Dovecot Replication with dsync
by Listas＠Adminlinux 04 Sep '14

04 Sep '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Is it possible to log a message custom header through Mail logger plugin or other method? It seems that there are a fixed number of info that is configurable via mail_log_fields (http://wiki2.dovecot.org/Plugins/MailLog) .. My custom header is X-VERTICAL-IP-Quarantine-ID and I want a log event like this one: Aug 27 09:48:13 imap dovecot: imap(user@domain): copy from INBOX: box=SPAM, uid=213, *X-VERTICAL-IP-Quarantine-ID=u7cnUqYDPA9a*, msgid=< 0.0.D7.290.1CFC155CE887302.0(a)etm2.com>, size=26481, vsize=26949, from==?UTF-8?Q?Dafiti=20-=20Parceiros?= <aaa@domain>, subject==?UTF-8?Q?Sapatos=20com=2040%OFF?==?UTF-8?Q?!=20Apro?=? =?UTF-8?Q?veite!?= -- Att.

Setup sieve failed
by Christian Vielhauer 03 Sep '14

03 Sep '14

Hi, I try to setup sieve but I have some trouble. Using dovecot 2.2.9 on Ubuntu 14.04.1 LTS. I replaced my correct domain with „domain.tld“. I am able to create sieve scripts using SOGo. The scripts are created in my mailbox. For example in /var/www/kunden/mail/domain.tld/testuser/sieve/sogo.sieve I have the following script and in same ~/sieve folder is a subdirectory available that’s called "tmp“: ~/sieve ~/sieve/tmp require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses [„testuser(a)domain.tld"] text: This is a vacation test message.

quota for subfolder with prefix=INBOX.
by Jogi Hofmüller 03 Sep '14

03 Sep '14

Hi all, We use prefix=INBOX. in order to keep things as they were on the old server. Now I started playing with quota and have trouble getting the additional quota for Trash and/or Junk working. My expectation was that once a user is over quota and moves email to trash sh/e should be able to receive new email again. That's what I cannot get to work with our setup. Attached you find the config that I thought should be working. The numbers are ridiculously low but that's just for testing. Here is some output from doveadm doveadm quota get -u user Quota name Type Value Limit % User quota STORAGE 5422 5120 105 User quota MESSAGE 18 - 0 doveadm mailbox status -u user "messages vsize" "*" INBOX messages=13 vsize=3147033 doveadm mailbox status -u user "messages vsize" "INBOX.*" INBOX.Drafts messages=0 vsize=0 INBOX.Sent messages=0 vsize=0 INBOX.Trash messages=5 vsize=2475790 INBOX.Junk messages=0 vsize=0 Regards, -- j.hofmüller We are all idiots with deadlines. - Mike West

Trouble viewing Inbox via IMAP Client

dsync-server couldn't create .dovecot-sync.lock file

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>.

mail_location hashing & lowercasing?
by Ralf Hildebrandt 31 Aug '14

31 Aug '14

Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax: mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that. %2NLn 2 Characters of the %N hash of %Ln (the lowercase username) But this gives me a verbatim "Ln" on the path! -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Need help to compile and install a minimal dovecot imap plugin
by Stefan Arentz 31 Aug '14

31 Aug '14

I am trying to create a plugin that adds a new IMAP capability. So far I have this: const char *foo_plugin_version = DOVECOT_ABI_VERSION; static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created; static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO"); if (next_hook_client_created != NULL) { next_hook_client_created(client); } } void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); } void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); } const char foo_plugin_binary_dependency[] = "imap”; On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with: cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c And then install with: sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/ (I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf) I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with: protocol imap { mail_plugins = $mail_plugins foo } But … nothing happens. No warnings, no errors, no crashes. How do I debug this? Am I missing something obvious? Does the naming of the plugin matter? S.

Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.
by Info Akra 30 Aug '14

30 Aug '14

Hi, Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files? I found that out the hard way (i.e. a week of debugging)!! in /etc/dovecot/conf.d/10-master.conf, the line: unix_listener /var/spool/postOut/auth/dovecot-auth { creates a: Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory but unix_listener /var/spool/postout/auth/dovecot-auth { works just fine (with matching case changes on the directory names themselves). That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9. — Hugo

Dsync setup... help needed
by Sinergizmas Sin ergizmas 30 Aug '14

30 Aug '14

Hello, I tried to implement Dsync (doveadm version 2.2.10) following https://www.evilcoder.org/2014/08/22/automatic-replication-with-dovecot/ but had no luck. SSH commands working quite well, but I need to respond more quickly. So TCP looks promising. I have Centos 6, Dovecot 2.2.10. I did everything that is written there, but after I restart dovecot doesn't sync. Then i ran netstat command but no service listen to port 12345 also. Iptables service are of in testing scenario...

Migrating courier to dovecot
by Patrick Lion 29 Aug '14

29 Aug '14

Hi, i want to migrate the following setup: postfix / courier-{imap/s,pop3/s,authlib} / maildrop / mysql I´m using the maildir format and quotas as well. My target is the following setup: postfix / dovecot / some sort of quota respecting lda / mysql What i`ve done already: SQL-Implementation for dovecot, login process and also sending mails via auth-userdb is already working. Quotas are read out from database and working. Before i mention my problems while implementing, here is the config im using at this time: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.14-gentoo x86_64 Gentoo Base System release 2.2 auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no info_log_path = syslog login_log_format_elements = user=<%u> method=%m ip=%r mpid=%e mail_debug = yes mail_location = maildir:.maildir mail_plugins = quota namespace inbox { inbox = yes location = .maildir 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 = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { args = /etc/dovecot/dovecot-sql.conf.ext quota = maildir:User quota quota_rule = %u quota_rule2 = trash:storage=+150M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=127.0.0.1 dbname=postfix user=postfix password=thereisone default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT concat('/', home, user, '/', destinationname) AS home, uid, gid, \ concat('*:storage=', round(quota / 1000 * 1.024)) AS quota_rule \ FROM mailbox WHERE username = '%u' Where user is the row where the admin-panel user is stored and username is the mbox-user. My problem is the LDA, with dovecot-lda im having the uid / gid trouble and i really dont want to suid oder sudo it. dovecot-lmtp just gives me status=deferred (host xx.xx[/var/run/dovecot/lmtp] said: 451 4.3.0 <box(a)xx.xx> Temporary internal error (in reply to end of DATA command)) Postfix virtual is working as well as maildrop, but no dovecot-implementation wants to, i also didnt find anything about the error above, except a bug in v2.2.2 and a google groups thread where users are just blaming each others for nothing .. I want to use a dovecot lda/lmtp because the quota settings for trash-folders are very nice and reducing my support times but im stuck at getting one of the dovecot-LDAs to work. Let me know if you need any additional information. Any help is greatly appreciated! -- Viele Grüße / Best regards Patrick

Multiple A Records for IMAP service
by Vijay Rajah 29 Aug '14

29 Aug '14

Hello All, I have a quick question. I have 2 MX servers each with a Dovecot Instances (2.2.6). These 2 Dovecot Instances are replicated by using Dsync... All works well. The questions is, Can I have 2 A records for my imap.mydomain.tld? The Idea being, if for any reason, one of the Dovecot IMAP instances are unreachable, the client can connect to the other Instance. (this is purely a fail over scenario). If it matters, The clients are Thunderbird, Android Native (default) Mail client, iOS Mail Client. -Thanks in advance Vijay

Documentation for /usr/lib/dovecot/imap executable
by Christoph Groth 29 Aug '14

29 Aug '14

Dear Dovecot experts, I'm in the process of setting up dovecot with mbsync as a local cache for remote IMAP servers. One recipe that I found involves using the /usr/lib/dovecot/imap (This is with Debian's dovecot package). For example, in .mbsyncrc I have IMAPAccount cwg-wf-local RequireSSL no Tunnel "/usr/lib/dovecot/imap -o mail_location=maildir:/home/cwg/.mail/cwg-wf" This works, but I wonder: is there any documentation for the /usr/lib/dovecot/imap executable? What options does it take? If there's no documentation: where can I find this command in dovecot's sources? Thank you, Christoph

Postfix + dovecot setup
by Timothy Murphy 29 Aug '14

29 Aug '14

I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks. As far as I can see there are 3 standard ways of setting this up: 1. Use amavisd 2. Use dovecot + pigeonhole/sieve 3. Use spamass-milter At present I'm following (2), but am thinking of going over to (1), since this seems simpler. (Amavisd wasn't available when I set up CentOS-7, so I didn't consider it then.) It seems to me that (2) is using dovecot in a slightly odd way, since as far as I can see dovecot normally takes email from ~/Maildir/cur/ and then moves marked spam. I'm not quite sure if (3) is a genuine alternative, or if it is why it is not the standard? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Hi all! Does dovecot cluster (with Proxy/Director) work only distributed filesystems (like NFS) ? Is Dovecot-replication + Ext4 recommended for production environments? Thanks! -- Thiago Henrique

Dovecot Master User

Hi, I'm trying to use imapsync to migrate my accounts and mailbox (mbox) of an server A (Postfix + Dovecot) to a Server B (Zimbra), without having to change user passwords on the server A, using a master user account. I'm using this paper http://wiki2.dovecot.org/Authentication/MasterUsers as guidance. The Dovecot server A, is not letting me authenticate.

POP/IMAP HA solution for 5k users
by Sinergizmas Sin ergizmas 28 Aug '14

28 Aug '14

Hello, I want to build simple, cheap HA solution for 5000 users with postfix/dovecot. Each user will have 1.3 GB mailbox (maildir) storage quota. All of the users will use POP and also plus half of them will use IMAP from smart phones. Sometimes they will hit webmail (squirrelmail). I plan that every user will send 20 and receive 20 mails per day. I have 3 locations, but electricity are not very stable there. We have outages for couple of hours 3-4 times per year. So I plan distribute all servers (it's more like good PC's) across locations. I'm very tied on budget also. Or maybe I could say I don't have it and I'm forced to use hardware equipment which is given. We are talking about quite pour HA solution here. Don't judge me please. I start to plan architecture and I would be very thankful for all your thoughts. I'm not expert in this area, but I need to learn, fire up email system and manage it. I will have SMTP server (smtp.example.com) which will filter mail with Clam, Spamassasin, Greylisting and forward emails to IMAP/ POP3/webmail server (mail.example.com) Mail.example.com will sync all user and mail changes to the third server mail2.example.com. Mail2.example.com server is just stand by, hot backup server in cases if main mail server or smtp will not be reachable. Locations of servers are in different cities: Locations #1 - SMTP servers as virtual machines (vmware server or virtualbox), with CPU i3, 6GB RAM, SSD, Centos 6, Virtualmin Location #2 - Dovecot/webmail server: CPU i5, 16GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2TBx4 LVM (total 8TB) for Maildir's, Centos 6, Virtualmin Location #3 HOT BACKUP (always online) server in case of mail.example.com or smtp.example.com failure, electricity outage and etc. It contains Dovecot/webmail server: CPU i3, 8GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2x4TB LVM (total 8TB), Centos 6, Virtualmin DNS configuration (and location number): IN MX 10 smpt.example.com. (#1) IN MX 20 mail.example.com. (#2) IN MX 30 mail2.example.com. (#3) .... smtp IN A aa.aa.aa.aa mail IN A bb.bb.bb.bb mail2 IN A cc.cc.cc.cc So I need to solve SMTP, POP, IMAP high availability tasks. SMTP I think will be ok for external users. SMTP feature has all three servers. If smtp.example.com server is offline mail is sent to mail.example.com If mail.example.com is offline, then mail is sent to mail2.example.com If mail2.example.com is offline, the senders SMTP server will hold an email in a queue by default for 3 days (in most cases) and will try to deliver in some intervals. Local (users of domain example.com) SMTP/POP/IMAP users will have problems, because their domain server will be dead. This means that connections from user MTA agents (outlook POP) could not be delivered because DNS A type record pointing to a degraded server. When problem with server mail.example.com (POP/IMAP/webmail) connectivity will happen, I think to login to DNS server and point record (A type) to a working server. So if server in location #2 mail.example.com is dead, I will change mail IN A bb.bb.bb.bb ----> cc.cc.cc.cc The same with the server smtp.example.com. If it's down, I will change mail IN A aa.aa.aa.aa ----> cc.cc.cc.cc I know that this method is not perfect because of ISP DNS caching around the globe, but this the only option I have. Most of my users use ISP that refresh DNS in a period of 30 minutes so it won't be very terrible to half of hour to wait for the connection. My questions: 1. Is this infrastructure is ok for 5000 users? If you think it's not, please write how many users it will serve "normally"? Or maybe I it could handle and 10 000 users load? 2. Is the logic of all setup is right in such situation like mine? What other problems could arise? 3. I prefer to create users from one server. So the LDAP option is the best for me? In case of LDAP it will be on server #2 and I need to replicate it to #3. Is it rigth? Then server #2 will be offline does #3 LDAP will take place? Or should I better use batch command to create user in each server per single command? Actually I do not want to manage and LDAP as extra service. I don't have experience with it. 4. The main problem is to synchronize maildir of POP/IMAP/webmail servers. Because of distance I do not want to use DRBD. It's not suitable for WAN connections. GlusterFS seems an option but.. I saw on internet users also having problems with it performance. Sometimes gluster hang and all cluster must be restarted. Maybe I can sync /home with gluster where maildir resides, but we need to take care of dovecot index and control files synchronization also. The performance of retrieving index'es by several thousands users every 2-5 minutes must be excellent. The only option I found is Dovecot Dsync (or newer Doveadm) command. I made initial tests on two servers, but only to get work with SSH command. The method using TCP connection doesn't work for me. So question, if I use SSH method in several thousand user system does it cause me trouble? SSH adds some overhead comparing to TCP. But could make a permament tunnel and TCP also would be quite secure. So please tell me what methods are you using to sync two mail servers (especially for POP accounts) in different locations? 5. File system. Is it ok to use EXT4 file system? I know that XFS is better in performance working with small files (maildir = a lot of small files), but in power outage it can become corrupted without journal. Thanks.

Moving from one Dovecot server to another Dovecot server
by Michael 28 Aug '14

28 Aug '14

Hi, I'm planning to move all mailboxes from a Dovecot 2.2.10 server to a Dovecot 2.2.9 server. Dovecot is serving virtual users only. I'm not sure if I can use dsync for that. According to the Wiki [1] the command to mirror my own mailbox should look like dsync -u mine(a)michi.su mirror ssh -i my_ssh_key vmail(a)my-mailserver.com dsync -u mine(a)michi.su Where vmail is the user that is used by Dovecot to access mail_location. I assume the above command will only mirror the mailbox of user mine(a)michi.su, right? Is it possible to sync all mailboxes with just one single command? Is it possible to sync also all ACL lists and sieve scripts? Is using dsync the right way for my purpose? Thanks, Michael [1] http://wiki2.dovecot.org/Tools/Dsync

At using virtual folder with fts, the dovecot crashes with following panic: Aug 20 10:49:43 imap(...): Panic: file fts-search-serialize.c: line 63 (fts_search_deserialize_add_idx): assertion failed: (*idx < buf->used) Aug 20 10:49:43 imap(test4(a)india.com): Error: Raw backtrace: /opt/dovecot2/lib/dovecot/libdovecot.so.0(+0x6c6ca) [0x7f93de51c6ca] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(+0x6c746) [0x7f93de51c746] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(+0x2542a) [0x7f93de4d542a] -> /opt/dovecot2/modules/lib20_fts_plugin.so(+0xc757) [0x7f93dd4e1757] -> /opt/dovecot2/modules/lib20_fts_plugin.so(fts_search_deserialize_add_nonmatches+0x1c) [0x7f93dd4e177c] -> /opt/dovecot2/modules/lib20_fts_plugin.so(+0xdafe) [0x7f93dd4e2afe] -> /opt/dovecot2/modules/lib20_fts_plugin.so(+0xdcd2) [0x7f93dd4e2cd2] -> /opt/dovecot2/lib/dovecot/libdovecot-storage.so.0(+0xa96da) [0x7f93de82b6da] -> /opt/dovecot2/lib/dovecot/libdovecot-storage.so.0(index_storage_search_next_nonblock+0x48) [0x7f93de82bd28] -> /opt/dovecot2/modules/lib20_virtual_plugin.so(virtual_search_next_nonblock+0x13e) [0x7f93dd2cd73e] -> /opt/dovecot2/modules/lib20_virtual_plugin.so(virtual_search_next_nonblock+0x7e) [0x7f93dd2cd67e] -> /opt/dovecot2/lib/dovecot/libdovecot-storage.so.0(mailbox_search_next_nonblock+0x27) [0x7f93de803f17] -> dovecot/imap() [0x41dddf] -> dovecot/imap() [0x41e462] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xbb) [0x7f93de52d23b] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x61) [0x7f93de52df81] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7f93de52ce89] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f93de52cf18] -> /opt/dovecot2/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f93de4d9f33] -> dovecot/imap(main+0x2a8) [0x421278] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f93de145cad] -> dovecot/imap() [0x40bda9] Aug 20 10:49:43 imap(...): Fatal: master: service(imap): child 7254 killed with signal 6 (core dumps disabled) imap-commands: telnet localhost imap ... 3 select virtual/all 4 search text searchtext - > panic crash (see above) So I do nothing special, I just do fts in the virtual folder.

LMTP and passdb deny=yes not working
by Jogi Hofmüller 27 Aug '14

27 Aug '14

Hi all, I start this on in a new thread. I setup the deny-user setting to temporarily prevent users from logging in and (that would be great) also stop mail delivery for said user. All this is because of our upcoming migration. Now it seems that lmtp is ignoring this setting. This is from the logfile: Aug 21 13:01:00 klee dovecot: lmtp(pid): Connect from IP Aug 21 13:01:00 klee dovecot: auth: passwd-file(fischer,IP): User found from deny passdb Aug 21 13:01:00 klee dovecot: lmtp(pid, fischer): 2UErAGzR9VMBPQAAGyzfLQ: sieve: msgid=unspecified: stored mail into mailbox 'INBOX' Aug 21 13:01:00 klee dovecot: lmtp(pid): Disconnect from 172.16.16.205: Successful quit So lmtp seems to find the user and correctly states the fact but then stores the email anyhow. Is this intended or did I hit a bug? Or do I have an error in my config? Cheers, -- j.hofmüller mur.sat -- a space art project http://sat.mur.at/

multiple IMAP sessions when connecting from one client
by Martin Vegter 27 Aug '14

27 Aug '14

Hello, I am using Postfix/Dovecot/IMAP. Everything is working fine, but I have noticed that every time I connect with Thunderbird to my server via IMAP, not one but 4 connections are being logged into /var/log/mail/mail.log: 2014-08-27 09:17:46 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12519, TLS, session=<uyb/N5cB+gBUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12521, TLS, session=<jioqN5cB/ABUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12523, TLS, session=<pqwwN5cB/QBUDFRB> 2014-08-27 09:17:54 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12525, TLS, session=<cffremmc/gBUDFRB> This looks like 4 separate sessions are created when I log in from one client. Is this normal behavior? Can somebody please explain why this is so? My Dovecot version is 2.1.7 regards, Martin

LMTP during dsync migration
by Jogi Hofmüller 27 Aug '14

27 Aug '14

Hi all, Another question regarding migration. While migrating a mailbox with dsync is it safe to deliver mail via LMTP to the new (target) mailbox or is it wiser to deactivate LMTP delivery to this mailbox until it's fully migrated? And what methods could I use to stop delivery to a mailbox during migration? Our user data is stored on an LDAP server. Cheers, -- j.hofmüller http://thesix.mur.at/

Special-Use Mailboxes ?
by Per Jessen 27 Aug '14

27 Aug '14

Lots of people must have had this issue before me - users using different devices&software (pc, smartphone, tablet, thunderbird, outlook, webmail) and languages (e.g. English on the PC, German on the iPhone), some folders end of with different names - e.g. "Sent" and "Gesendete Elemente" - meaning the same thing, namely "sent mails". How do you map these to just one folder such that it shows up correctly independently of what the user happens to be using? It sounds like something for the mailbox "Sent" { special_use = \Drafts } config directive? Is that what it might be used for? mailbox "Sent" { special_use = \Sent } mailbox "Gesendete Elemente" { special_use = \Sent } -- Per Jessen, Zürich (12.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.

Object storage
by List 26 Aug '14

26 Aug '14

Timo, We are contemplating building an S3 compatible cluster of storage servers using Pithos <https://github.com/exoscale/pithos> and Cassandra to get multi data center redundancy and availability. Would it be possible to have multiple Dovecot servers in disparate geographical locations all talking to the same object storage, assuming it's consistent between sites? From what I remember about obox the dovecot servers all keep a copy of the index locally and merge it with a file in the object storage at intervals, is this an issue with our concept? Also does your team have any performance analysis data on the obox plugin, or data on it's use in production?

OS X 10.6 Server - Dovecot Issue
by Ian Baker 25 Aug '14

25 Aug '14

I've just taken over support for an OS X Server (v10.6.8) box, and am a bit new at Postfix & Dovecot. We're having an problem where, intermittently, dovecot seems to be bouncing messages inbound for some of my existing users. Here is the mail.log entry for a successful delivery: Aug 21 16:58:45 mail postfix/pipe[64094]: D68783AE0F75: to=<sblondin(a)eem.ca>, relay=dovecot, delay=0.08, delays=0/0.01/0/0.07, dsn=2.0.0, status=sent (delivered via dovecot service) And here is what a bounce looks like Aug 22 07:29:28 mail postfix/local[93916]: error: od[getpwnam_ext]: No record for user sblondin Aug 22 07:29:28 mail postfix/pipe[93944]: 852C43AE7ACC: to=<sblondin(a)eem.ca>, relay=dovecot, delay=15, delays=0.14/0.05/0/15, dsn=5.1.1, status=bounced (user unknown) And a bit later another succcessful delivery.

dict SQL : HA / RR load-balancing ?
by Florent Bautista 25 Aug '14

25 Aug '14

Hi everyone, I am using Dovecot 2.2 with dict SQL. My config is using : connect = host=10.111.5.1X host=10.111.5.1Y host=10.111.5.1Z dbname=mail user=quota_updater password=xxxxxxxx But when an SQL server is down, I have these messages in logs : dict: Error: mysql(10.111.5.1Y): Connect failed to database (mail): Can't connect to MySQL server on '10.111.5.1Y' (111) - waiting for 125 seconds before retry Does Dovecot support HA / RR load-balancing in dict SQL, as in passdb/userdb ? Thank you.

does dovecot assume ~ = /home/userid ?
by Per Jessen 22 Aug '14

22 Aug '14

See $SUBJ - or is there a setting somewhere to control this? I have a userid = user(a)example.com with homedir (from /etc/shadow) = /home/example.com/user, but when dovecot wants to find e.g. ~/.dovecot.sieve , it looks in /home/user(a)example.com .... Doing "su - user(a)example.com" puts me in the correct directory. -- Per Jessen, Zürich (22.3°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland.

Dovecot authentication LDAP SSL-TLS againts SAMBA4
by Lista de Dovecot 22 Aug '14

22 Aug '14

Hi, i would like to know if anybody have implemented the authentication of dovecot against samba4 via secure ldap (SSL/TLS). I made it but in plain text through dovecot´s offical page: http://wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds http://wiki2.dovecot.org/AuthDatabase/LDAP But when i try to do it in a secure way i can´t make it work. Samba4 is listening by port 636 and dovecot is speaking by 389 or 636, but they can´t comunicate themself. I´m wondering if any of you have done this before or have any clue that might help me. Thanks.

Avoid "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)"
by Florent Bautista 22 Aug '14

22 Aug '14

Hi all, I have a Dovecot setup (2.1, I will switch to 2.2 soon) with one Director and 2 backend servers. When my MX server (Postfix) tries to deliver mail to Dovecot via LMTP, it often gets an error "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)" from the Director. Service LMTP is configured with "client_limit = 1" on Director en backends (others limits are default ones). Postfix is using "lmtp_destination_recipient_limit = 1" and "lmtp_destination_concurrency_limit = 1". I want that incoming messages are stored one after one per recipient (have a queue per recipient). I does not seem to be done actually. I think Postfix is sending too many messages at a time to Director. How do you do to handle that ? I already applied the 3 patches available on the list for 2.1, but it does not seem to solve my problem... Thank you a lot. Florent

Folders don't show up
by Christian Hudon 22 Aug '14

Hello, I've upgraded to the new LTS version of Ubuntu. With that comes a new dovecot version. I think I've migrated my dovecot configuration correctly to the new version. Everything works, except that the mailboxes don't show up in the list of mailboxes in my mail clients. Trying to issue a LIST command, I see the following: CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot (Ubuntu) ready. 1 login USERNAME_HERE PASSWORD_HERE 1 OK [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 SPECIAL-USE BINARY MOVE] Logged in 2 LIST "" "*" * LIST (\HasNoChildren) " * LIST (\HasNoChildren) " [SNIP...

I'm not an IMAP protocol expert, but those answers to the list command don't quite look like valid IMAP to me. My imapdir has a bunch of maildir directories in it, like a normal imapdir should. Everything worked fine with the previous version of dovecot (1.2?). Maybe a dovecot bug? At least I don't see how my config could cause this. Any help would be appreciated.

Thunderbird not able to edit sieve Message Filters
by Peter Bell 22 Aug '14

22 Aug '14

I'm not sure when this problem first occurred - it is many months since I last editted a sieve filter. I am certainly several versions of Thunderbird and, probably, a few versions of Dovecot on from when I last editted a sieve filter. However, I do know that I have done so in the past. I have just built Dovecot 2.2.13 and Pigeonhole 0.4.3, installed and running on Slackware 14.1 x64. I am running an up-to-date version of Thunderbird (31.0) on Arch Linux x64. The sieve filters are definitely being applied to incoming mail, and working perfectly well. However, when I attempt to edit the Sieve Filters (from Thunderbird Tools->Sieve Message Filters...), the Sieve Filters tab is displayed, but not populated (eg, the Server Sieve Capabilities are not displayed, and there is an endless 'hourglass' displayed in the main mailfilters pane. Does anyone recognise the symptoms and can advise how to resolve the problem, or suggest what logs I should examine/post in order to identify the cause? -- ------------------------------------------------------------------- Peter Bell Mob: +63 (0) 9287 340 343 Tagum City, Philippines.

Assertion in istream.c::167 in POP3 mode when maildir content has wrong S value (using 2.2.13)
by Rolf Eike Beer 21 Aug '14

21 Aug '14

Hi, the affected machine is running 2.2.13 on Gentoo x86_64. For me it looks like the old size is still in some struct or whereever even after the file has been renamed. I see that there are many commits following 2.2.13, is that possibly already fixed or do I need to dig in the code? The original problem seems to be that maildrop uses the file size before piping the mail into spamassassin even if the mail is bigger afterwards. Not relevant here, but in case anyone wonders how this happens. Greetings, Eike Error: Cached message size smaller than expected (81118 < 81308) Error: Maildir filename has wrong S value, renamed the file from /var/vpopmail/domains/example.org/user/.maildir/cur/1408452738.16341.mail,S=81118:2, to /var/vpopmail/domains/example.org/user/.maildir/cur/1408452738.16341.mail,S=81308:2, Error: Corrupted index cache file /var/vpopmail/domains/example.org/user/.maildir/dovecot.index.cache: Broken physical size for mail UID 65 Panic: file istream.c: line 167 (i_stream_read): assertion failed: (old_size <= _stream->pos - _stream->skip) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x6bbef) [0x7f50652a4bef] -> /usr/lib64/dovecot/libdovecot.so.0(+0x6bc4e) [0x7f50652a4c4e] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f506525e2be] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x214) [0x7f50652ad904] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7f50652adfed] -> /usr/lib64/dovecot/libdovecot.so.0(message_get_body_size+0x9d) [0x7f5065299b3d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x200) [0x7f506556f700] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x2dd0f) [0x7f506553cd0f] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_get_stream+0x4b) [0x7f506554915b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x2dae7) [0x7f506553cae7] -> dovecot/pop3(client_create+0x56d) [0x40622d] -> dovecot/pop3() [0x404ea3] -> dovecot/pop3() [0x40508f] -> /usr/lib64/dovecot/libdovecot.so.0(+0x28346) [0x7f5065261346] -> /usr/lib64/dovecot/libdovecot.so.0(+0x28841) [0x7f5065261841] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x4e) [0x7f50652b58de] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xd7) [0x7f50652b68b7] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7f50652b5969] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f50652b59e8] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f50652635a3] -> dovecot/pop3(main+0x233) [0x404bf3] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5064eb6db5] -> dovecot/pop3() [0x404d49]

About network throughput between Director and backends
by Listas＠Adminlinux 21 Aug '14

21 Aug '14

I plan to migrate my Dovecot IMAP servers to a clustered structure. I'm planning a cluster with high availability and load balancing. I know I need instances of Dovecot Proxy / Director. But these instances can be on another network? There is need for high network throughput between the Director and the backends? For me it would be cheaper to run Director in VM's at Amazon AWS for example. Thanks! -- Thiago Henrique

doveadm proxy list
by Claus 21 Aug '14

21 Aug '14

Hi, i have configured my dovecot-proxy with "shutdown_clients = no" and "service_count = 1" for a "default_process_limit = 5000" and "default_client_limit = 25000". I don't know if this is a prefered setup for so many users/concurrent sessions but so i can reload my dovecot without disconnecting all sessions. The main problem are pop3 sessions - if i kill them, the mailbox remains locked and the client gets an error. Back to my problem: If i reload dovecot the "doveadm proxy list" shows me the list of the new processes. Is there any possibility to see the stats of the old sessions (user,source,destination) ? greet's Claus PS.: Could someone explain me why i have to set default_client_limit to 5x default_process_limit?

rebuilding indexes for dovecot pop3
by Arkadiusz Miśkiewicz 21 Aug '14

21 Aug '14

Hi. doveadm -D fetch -u login \ 'imap.envelope imap.bodystructure size.virtual date.received' '*' according to mail archives allows to regenerate indexes and precache specified headers for imap usage. What headers are needed for dovecot pop3 daemon? I have one server where dovecot works for imap only. For pop3 there is different software being used. I want to migrate to dovecot pop3 but I need to precache and regenerate indexes for dovecot pop3. Note, some users used pop3 only, so dovecot imap had no chance to generate any indexes.

Hi Gedalya, I am very sorry for not having replied on-list. That was not my intention!

Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/'
by Philipp Faeustlin 21 Aug '14

21 Aug '14

Hello List, with dovecot version 2.2.13.9, I actually have a problem using lazy_expunge and acl together. Shared/Public Folders work fine with lazy_expunge disabled. If lazy_expunge is enabled and userA got a shared folder form userB, then there is the error shown in subject. My test case to reproduce the error. doveadm mailbox list -u userA@domain --> Output Fine. doveadm acl set -u userB@domain INBOX user=userA@domain lookup read write write-seen write-deleted insert expunge create --> Fine. doveadm mailbox list -u userA@domain --> Some output and then: --> doveadm(userA@domain): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' I think this is a bug in dovecot, can someone of the dovecot developers or someone else confirm this? If it is not please show me the fault in my configuration.

New user mailbox permission
by Gionatan Danti 21 Aug '14

21 Aug '14

Hi all, I have a problem with my Dovecot installation. First, some informations: - OS: CentOS 6.5 x86_64 - Dovecot: dovecot-2.0.9-7.el6.x86_64 Config: mail_location = sdbox:~/dbox user_query = SELECT username, password, 'vmail' as uid, 'vmail' as gid, '/var/vmail/%d/%n' as home, CONCAT('*:storage=', (quota DIV 1000)) as quota_rule FROM mailbox WHERE username='%u' What I want to do is to create a backup user to rsync the mailstore to a remote location. If possible, I don't want to use the root user for this operation. I already added the backup user to "vmail" group. The problem is that when a new user is created, it's base directory permission are 0700 (vmail:vmail). From what I read here (http://wiki2.dovecot.org/SharedMailboxes/Permissions, "Permissions to new /domain/user directories"), simply using the setgid bit is not sufficient because I am not using an absolute path for mail_location. My questions are: 1) all I need to do is to switch to an absolute mail_location? 2) it is possibile to solve my problem _without_ altering mail_location?

How to configure read-only access during a migration?
by Jeffrey Tunison 20 Aug '14

20 Aug '14

Hi. I would appreciate your advice about these TWO PROBLEMS: ======================================================= Find the simplest way to A) configure a Dovecot 2.2.10 IMAP server to access (existing) email users' (mbox-format) mail folders ****in read-only mode.**** B) Do the above while allowing a master_user to access mail on behalf of real users. (I've got master_user access working in read-write mode.) Simplest because while I'm proficient at UNIX systems administration, I'm under time pressure and dovecot has a lot of configuration flexibility. Identifying the right way to do this is proving time- consuming. Namespaces? ACL's? passdb's? I thought it was time to bring in the dovecot wizards. You! GOAL: ======================================================= Without knowing or changing users' passwords, migrate several hundred users of dovecot IMAP to MS Exchange using the commercial product Transend. I'm manging the dovecot side, someone else is doing the Transend/Exchange piece. Migration would occur in batches due to slowness of the Transend side when dealing with users with email collections over a few gigabytes. I have a production IMAP server (dovecot 1.0.13 on 32-bit RHEL 4.9). Let's call it PROD for short. Users INBOXes are stored locally on PROD. Their other mail folders are stored on a second machine and accessed via NFS. Those other folders contain the great majority of the email to be migrated. Let's call the NFS server MIGR for short. On MIGR, I've set up a migration IMAP server (dovecot 2.2.10 on 64-bit RHEL 5.10). MIGR is a dedicated NFS server with newer hardware than PROD. It has an unused Ethernet NIC I can tell Transend to use. Both PROD and MIGR use NIS for authentication. Therefore PAM is consulted for passdb information, normally. No SQL db's used. I set up the second server (MIGR) for several reasons: 1) there are some users mail folders larger than the 32-bit file size limit found on the PROD server. 2) the bulk of the email is stored locally on the MIGR server. 3) the version of dovecot is much newer and therefore more likely to have fewer bugs and more configuration options. 4) I don't want to modify the production environment except where really necessary. Pointing Transend at MIGR instead of PROD seems like it will be faster and better. Telling end-users to use MIGR instead of PROD would allow them to verify that their email came across okay (into MS Exchange) without being able to modify the original copy of email (in Dovecot). In the days and weeks after migration. I may need to re-enable write access on PROD for certain users if the migration does not succeed. Transend has been dying on a number of test users despite tweaking its parameters in consultation with the vendor. "Corrupt" messages seem to be the issue. Users (or sysadmins) might be required to identify and delete the offending messages before we retry their migration. (Which folders and which messages are causing problems will hopefully be discernible in Transend logs.) Ha! If you've read this far, then I'd also say that I welcome any advice on changes to increase performance on MIGR, such as whether trying to minimize indexing as I've done is useful. Current configurations of the two servers follow. =========================================================================== PRODUCTION: =========================================================================== # 1.0.13: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log protocols: imaps imap listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_processes_count: 20 login_max_processes_count: 500 max_mail_processes: 1524 first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot-indexes/%u/ mbox_read_locks: dotlock mbox_write_locks: dotlock mbox_dotlock_change_timeout: 60 mbox_min_index_size: 2048 namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: Mail/ hidden: yes namespace: type: private separator: / prefix: ~/Mail/ hidden: yes namespace: type: private separator: / prefix: mail/ hidden: yes namespace: type: private separator: / prefix: ~/mail/ hidden: yes auth default: master_user_separator: * verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot.transend master: yes passdb: driver: shadow passdb: driver: pam userdb: driver: passwd =========================================================================== MIGRATION: =========================================================================== # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.18.1.el5 x86_64 Scientific Linux release 5.10 (Boron) auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_verbose = yes auth_verbose_passwords = plain first_valid_uid = 100 log_path = /var/log/dovecot.log mail_debug = yes mail_location = mbox:~/Mail:INBOX=/var/spool/concmail/%u:INDEX=MEMORY mbox_min_index_size = 50048 B mbox_write_locks = fcntl namespace four { hidden = yes location = prefix = ~/mail/ separator = / } 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 = } namespace one { hidden = yes location = prefix = Mail/ separator = / } namespace three { hidden = yes location = prefix = mail/ separator = / } namespace two { hidden = yes location = prefix = ~/Mail/ separator = / } passdb { args = /etc/dovecot/dovecot.transend driver = passwd-file master = yes } passdb { driver = pam } protocols = imap service imap-login { process_min_avail = 15 service_count = 10 } service imap { process_limit = 2048 } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 1000 }

LMTP re-reading all messages
by Florent Bautista 20 Aug '14

20 Aug '14

Hi all, I have a little problem with Dovecot 2.1.17 and MailDir accounts. I was using a shared file system (MooseFS), and all was pretty stable. Now I'm switching to CephFS, and Dovecot LMTP have problem to deliver mails. Very often, on large accounts, LMTP processes are running for a few hours before delivering the message. When I strace it, I can see that they are reading (open and stat operations) ALL the messages of the account. I was thinking to an index problem, but I think that after hundreds of delivered mails, indexes are rebuilded and problem should be solved. But not. The same way, If user connects to IMAP, a lot of IMAP processes get stuck on "getquotaroot" command (multiple processes for a single account). The previous FS didn't support mmap, so I disabled it. The new one supports it, so I enabled it, but it does not solve the problem. Do you have an idea of why Dovecot (LMTP or IMAP) spend a lot of time on large accounts ? Thank you a lot. Florent

Dovecot v2.2 FTS is not indexing "text/html" emails...
by Akash 20 Aug '14

20 Aug '14

Hi, I am not sure its intended or a fault in the newest Dovecot versions. I have been using Dovecot v1.2.15 on Debian squeeze and FTS is working as expected. When I search a quoted string "very good", I get 107 results including plain and HTML emails which have this phrase. In order to compare the benefits of lucene over squat, I recently started testing dovecot v2.2.13 on Debian Sid with the same maildir content. But now the same search "very good" yielded just 8 results. I thought it could be some problem with lucene so I tried switching to squat and got 107 results again. After this I deleted the old squat search index files created by v1.2.15 and re-indexed the mail-box by using doveadm index command. Now the same squat search is giving 8 results just as lucene. So I have realized that its not a problem with just lucene but FTS in newer dovecot isn't indexing those emails which have Content-type as text/html. Thus if a mail is like this: Content-Type: text/html <b>He is very good.</b> It isn't shown in search by the squat indexes created using dovecot v2.2.13. I have done further testing on some sample emails which confirmed this behavior. Why is this so? -Regards, Akash

auth_username_translation and LTMP problem
by Arkadiusz Miśkiewicz 20 Aug '14

20 Aug '14

auth_username_translation seems to be appliet on RCPT TO address of LTMP transport. Why dovecot is doing that? And better question - is there a way to disable auth_username_translation for LTMP but leave enabled for the rest (imap, pop3 etc) ? Background: I'm doing auth_username_translation = @= to allow logins like aaa(a)bbb.pl to be internally translated to aaa=bbb.pl. That works fine. Now my exim delivers mail to dovecot using LTMP and it does translation or it own, so it does: RCPT TO: <aaa=bbb.pl(a)mymbox.pl> Unfortunately looks like dovecot it doing translation one more time and looking in user database for aaa=bbb.pl=mymbox.pl where such user doesn't exist. Only aaa=bbb.pl user exists. Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

Mail Archiving/Lucene Indexes/mbox
by Larry Rosenman 20 Aug '14

20 Aug '14

I have a script (available on demand) that moves all my mail for a given month to a separate NAMESPACE (#ARCHIVE). When I do that, the lucene-indexes folder in the PRIMARY namespace seems to get cleaned out, and NOTHING gets put in the lucene-indexes folder (although it gets created) in the #ARCHIVE namespace. Is this to spec? the archiving is done via doveadm move commands.

Segfault with indexer-worker using Tika/Solr
by G H 20 Aug '14

20 Aug '14

Using Dovecot 2.2.13 with Tika 1.5 on Centos 5 64bit Tika is throwing an exception for some reason, which seems to be causing Dovecot's indexer to segfault. I'm using mdbox/gzipped compressed mail and private indexes for the shared folder. I'm importing mail via formail/dovecot-lda: formail -s /usr/libexec/dovecot/dovecot-lda -d admin -m Public/TestSubFolder < /tmp/Inbox.mbox dovecot -n and the GDB backtrace are attached. # find /var/mail/ -maxdepth 2 /var/mail/_public /var/mail/_public/dovecot.mailbox.log /var/mail/_public/dovecot-uidvalidity /var/mail/_public/dovecot-uidvalidity.53ecade1 /var/mail/_public/storage /var/mail/_public/subscriptions /var/mail/_public/mailboxes /var/mail/admin /var/mail/admin/dovecot-uidvalidity.53ecade2 /var/mail/admin/dovecot.mailbox.log /var/mail/admin/public /var/mail/admin/dovecot-uidvalidity /var/mail/admin/storage /var/mail/admin/subscriptions /var/mail/admin/mailboxes

BUG: Solr FTS engine appends domain name to index records
by G H 20 Aug '14

20 Aug '14

The Solr FTS engine appends domain names to the "user" and "id" fields inside Solr when indexing. However, when an IMAP search is performed, the domain name is not appended, resulting in 0 results, 100% of the time. You can reproduce this by setting up dovecot to have user names like "admin", "james", etc (as opposed to admin(a)example.com) Then import some mail (ie: "dovecot-lda -d admin < /tmp/mymail.txt"). Now attempt to search for that mail and it will not be returned as a result. You can see in the Solr GUI (http://xxxx:8983/solr/) that record is indexed as: { "uid": 1, "box": "7dff0b0d4f84df53f25300003d823887", "user": "admin(a)example.com", "id": "1/7dff0b0d4f84df53f25300003d823887/admin(a)example.com", "_version_": 1475511406809841700 } However, the IMAP search is sent to Solr performed with user:"admin" instead of user:"admin(a)example.com". Either the Solr FTS plugin needs to not append the domain name or the search does need to do so.

Trouble getting public folders working
by Bjarne Mark Kondrup 20 Aug '14

Hi i have trouble getting my public folders working properly. I have a few issues atm with them. First off i'm using version 2.0.9 as it came with CentOS and would greatly prefer to keep this version. Here is my dovecot.conf file # dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.23.3.el6.centos.plus.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no first_valid_uid = 101 last_valid_uid = 101 login_greeting = Dovecot ready.

I cannot get shared folders to work with pr. user settings. What i want is a public folder that all my users can see but each user marks mail as read individually. Atm no matter how i set it up if user1 marks a mail as read, then user2 will also see that mail as read :( 2. ACL to control the permissions. Right now all users can move mail and remove mail from the shared folders. I want people (except a few specific users) to be read only on this public folders. 3. Need to know if i'm creating the folders correctly. Right now i'm under my shared folder directory creating shared_folder and 3 subfolders beneath it (cur, new and tmp). After this it shows up in eg. roundcube and i can subscribe to it. I have read all the documentation and tried all the solutions i can. Mostly moving the index and/or config files to seperate dirs and from my understanding that should give each user their own index file marking what mails have been read ect. But this doesn't happen. Hope you guys are able to help me out a little here. -Bjarne

Huge difference between the lucene index size created by v2.1 and v2.2
by Akash 20 Aug '14

20 Aug '14

Hi everyone, While examining dovecot versions v2.1 and v2.2 for their lucene search performances, I have noticed a huge difference in the index sizes created by them. Both versions were compiled on same system, against same libclucene, same configure options and were used with same dovecot.conf during run-time. I deleted the lucene-indexes folder and dovecot* files in the Maildir prior to indexing with both versions. The tests were performed on a untouched mail archive folder containing 300000 mails without any dovecot* files in it: root@server:/home/admin/mails/.Archive# ls -l total 78640 drwx------ 2 2500 2500 14098432 Aug 17 22:16 cur drwx------ 2 2500 2500 12435456 Jul 30 09:46 new drwx------ 2 2500 2500 4096 Aug 2 13:02 tmp The command used was: doveadm -v index -u admin Archive After search indexing on v2.1 resulted in: root@server:/home/admin/mails# ls -lh lucene-indexes total 390M -rw------- 1 2500 2500 390M Aug 18 07:03 _25.cfs -rw------- 1 2500 2500 20 Aug 18 07:03 segments.gen -rw------- 1 2500 2500 46 Aug 18 07:03 segments_4d Whereas dovecot v2.2 resulted in: root@server:/home/admin/mails# ls -lh lucene-indexes total 1.5G -rw------- 1 2500 2500 1.5G Aug 18 06:41 _5g.cfs -rw------- 1 2500 2500 20 Aug 18 06:41 segments.gen -rw------- 1 2500 2500 46 Aug 18 06:41 segments_az 390M vs 1.5G. That is a huge difference in size. Why is that? Thanks in advance. -Regards, Akash

Problems with dovecot 2.2.13 and monit
by Hanno Böck 20 Aug '14

20 Aug '14

Hello, When I upgraded my servers to dovecot 2.2.13 the monitoring tool monit started to send out warnings that it couldn't reach my imap/pop3 servers through ssl any more. The same problem didn't happen on non-ssl-connections. According to people on the monit list this is likely a dovecot issue: https://lists.gnu.org/archive/html/monit-general/2014-06/msg00031.html Let me quote: > the root cause of the error is, that dovecot 2.2.13 closes the > connection if SSL is used in response to LOGOUT command instead of > sending usual response. When no SSL is enabled, dovecot responses to > LOGOUT command normally. [...] > According to RFC 3501 (http://tools.ietf.org/html/rfc3501) LOGOUT is > any-state command, where the server MUST send response before closing > the connection: http://tools.ietf.org/html/rfc3501#section-3.4 > > => the problem is caused by dovecot 2.2.13 bug ... its behaviour is > inconsistent (LOGOUT in non-authenticated state works per RFC > requirement if no SSL is used and doesn't conform to RFC if SSL is > used). It is possible that the problem is related to their DoS-attack > modification, which has most probably unexpected side-effect. Maybe this is related to the DDoS-protection measures that have been added in dovecot 2.2.13. Would apprechiate if someone could have a look. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

IMAP on 993/SSL or 143/STARTTLS?
by Alex 18 Aug '14

18 Aug '14

Hi, I have a postfix+dovecot-2.2.13 system and have configured it to support IMAPS on 993 with SSL/TLS. I'm noticing with users using Thunderbird, the autodetect defaults to IMAPS on 143 with STARTTLS. Which is preferred? Which is more secure? Which is more common? Why would someone choose one over the other? Can I ask the same question about SMTP and submission? Why would one choose 587 with STARTTLS versus 465 with SSL/TLS? Thanks, Alex

Hi, I am having the same issue as: http://www.dovecot.org/list/dovecot/2014-April/095681.html although I am using the latest dovecot-core and dovecot-lucene packages from the debian sid repo which already has the patch (http://hg.dovecot.org/dovecot-2.2/rev/5e42a8c18b51) mentioned in the above thread implemented. doveadm(admin): Info: Old.All: Caching mails seq=1..300332 9400/300332 Program received signal SIGSEGV, Segmentation fault.

Dovecot failing with exit code 19200 in cron job
by Murray Trainer 18 Aug '14

Hi All, I am synchronizing a few hundred dovecot mailboxes with a perl script via a crontab. It works for a while (ie exit status=0) but the rest then start failing with exit code 19200. I tried redirecting STDERR but showed nothing. I suspect the cron job is hitting some sort of resource limit? If I run the perl script from the command line it appears to dsync all the accounts OK. The relevant part of my Perl code is below. Any ideas? Thanks, Murray foreach (@userlist) { my $email = $_; chomp ($email); # get rid of CR logit("Started sync of mailbox $email") if $debug; my $dsync_command="dsync -v -D -u $email mirror ssh -C root@$mailstore dsync -u $email"; logit("dsync_command=$dsync_command"); # Run dsync of mailbox logit("Started secondary sync of $mailbox to $mailstore") if $debug; my $exit_status = system ( $dsync_command ); logit("Dsync exit status: $exit_status") if $debug; logit("Finished secondary sync of $mailbox to $mailstore") if $debug; }
