[Dovecot] dsync in a cronjob to replace offlineimap
by Guilhem Moulin 24 Mar '14

24 Mar '14

Hi list, Replacing offlineimap with dsync for IMAP-to-IMAP synchronization (using dovecot 2.1.7) is working great, but now that I upgraded to 2.2.9 I'd like to take advantage of the incremental replication [1]. I don't think having a separate replicator process & notifications suits my configuration, as I want to sync my server with my laptop which is not always on or might be behind a firewall. After reading ‘replication/replicator/dsync-client.c’ I was thinking of writing a small wrapper around dsync performing a daily full replication and updating the state otherwise. The following works great in a cronjob doveadm sync -l30 imap.example.org but when I try to get the current state doveadm sync -l30 -fs '' imap.example.org >~/mail/dsync.state and later use incremental replication state=$(< ~/mail/dsync.state) doveadm sync -l30 -s "$state" imap.example.org >~/mail/dsync.state the state seems to somehow quickly become "stale" and messages stop being retrieved from the server. I understand that dsync's incremental replication is mostly intended to be used by the replicator process, but I'm wondering whether it's also possible to use it manually ;-) If so, how to keep a sane state? Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/Replication

[Dovecot] Where can I find a stable PPA?
by Daniel Reynolds 22 Mar '14

22 Mar '14

Hello, As the subject says, where can I find a stable PPA of Dovecot v2.2 for Ubuntu 12.04? I found this <https://launchpad.net/~kokelnet/+archive/dovecot22>, but the description says, "...I declare them as unstable." For obvious reasons, I don't want to use this. What should I do? Thanks, Daniel

[Dovecot] Debian Wheezy Dovecot Replication no updates on message deposit
by Milan Cvetkovic 21 Mar '14

21 Mar '14

Hi, I am trying to setup dovecot replication based on: http://wiki2.dovecot.org/Replication http://www.dovecot.org/list/dovecot/2013-January/087674.html I know that 2.1.7 is dated, but I would refrain from upgrading, if not necessary. The problem I have is pretty much same as the one described in http://www.dovecot.org/list/dovecot/2013-January/087674.html: I have vmail user on both systems, setup with ssh public key logins with empty passphrase. Apparently, dsync happens only on periodic updates. If a message is deposited on one server, it will only propagate to the other once a while. Thanks, Milan. Here is doveconf -n output: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 auth_mechanisms = plain login mail_location = maildir:~/Maildir mail_plugins = " notify replication" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace 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 = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_replica = remote:vmail@192.168.108.138 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve pop3" replication_full_sync_interval = 1 hours service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service auth { unix_listener auth-client { mode = 0660 user = Debian-exim } } service config { unix_listener config { user = vmail } } service doveadm { user = vmail } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/exim4/exim.crt ssl_key = </etc/exim4/exim.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " sieve" }

[Dovecot] Dovecot + roundcube -- Password Change
by Vijay Rajah 21 Mar '14

21 Mar '14

Hello, I'm using Postfix + Dovecot (2.2.6) + roundcube 0.8.x + mysql. The roundcube webserver is hosted on a different server than the Dovecot. The dovecot itself is a replicated 2 node configuration. I would like to allow users to change the password from roundcube interface. All the examples I have seen, assume that roundcube runs in the same server as dovecot. Is there an example / documentation to enable this to work, applying reasonable security measures. -Thanks Vijay

[Dovecot] Password hashing issue
by Daniel Reynolds 20 Mar '14

20 Mar '14

Hello, First off, thanks in advance for all of your help. Now to my issue: I am setting up my first email server. It will be for just me and a few other people. I am using an Amazon EC2 server running Ubuntu 12.04. My MTA is postfix. As I said, this is my first time setting up an email server, so I am following a guide that Arstechnia has published (link<http://arstechnica.com/information-technology/2014/03/taking-e-mail-back-pa…> ). My issue comes when I try to create a hashed of my passwords. I have tried entering the command, "doveadm pw -s SSHA512". When I do this, I get the error message, "doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/99-mail-stack-delivery.conf line 6: Unknown setting: ssl_client_ca_dir". I have tried running that command with sudo and as root, but I still get the exact same error message. I had configured /etc/dovecot/conf.d/99-mail-stack-delivery.conf earlier on, and line 6 of that document says, "ssl_client_ca_dir = /etc/ssl/certs" which is exactly what the ars guide told me it should say. What have I done wrong? Thanks again, Daniel

Re: [Dovecot] versioning of mailbox index files
by morrison 19 Mar '14

19 Mar '14

My current approach is to introduce a index version file .dovecot.index.version in each mailbox and hooks mailbox_allocated event via my own plugin. If the version file does not exist or exist but with version number which need to be upgraded, index files in that mailbox are removed. I also tried to hook mailbox_opened() event and found that event was too late (index was loaded already). The side effect of hooking mailbox_allocated is that the event fires not only by 'select' command. 'list' command can also trigger a lot of mailbox_allocated events. Are there any better hook points I can use for this purpose? Thanks,

[Dovecot] Using a Sieve script to handle delivery to public mailboxes
by Alessandro Menti 19 Mar '14

19 Mar '14

Hello everyone, I'm setting up a Postfix+Dovecot stack with virtual domains and public mailboxes. I set up a shared mailbox "office(a)mydomain.com" as described in the Dovecot Wiki [1], that is: - I created the directory "/var/mail/mydomain.com/public/" and inside it I created the ".office" mailbox; - I added an appropriate ACL to allow the account "president(a)mydomain.com" to read and edit that mailbox under a public namespace; - I added a Sieve script to handle delivery to the public mailbox (its location is /var/mail/mydomain.com/public/.office/.dovecot.sieve). Some other relevant details about my configuration: - The backend used by Postfix and Dovecot to handle virtual aliases/domains/maps is a MySQL database. Since the virtual user table is used by other applications as well, I decided to keep it "clean" and to make use of another "virtual mailboxes" table (see /etc/dovecot/dovecot-sql.conf.ext below). The password_query setting returns only results from the virtual user table (so that only real users can authenticate on the IMAP server), while the user_query setting returns results from both the virtual user and the virtual mailbox table (so that dovecot-lda can choose the correct mailbox). - The queries saved in password_query and user_query return the correct results when executed manually: the home directory for the "office(a)mydomain.com" virtual mailbox is set to /var/mail/mydomain.com /public/.office. - Delivery from and to the "president(a)mydomain.com" account is regular, and that account is able to access the "office(a)mydomain.com" virtual mailbox (I have tested this by speaking IMAP to the server and by performing a manual check using Thunderbird). I encountered a problem with this setup: when I send a message to the "office(a)mydomain.com" account, the Postfix logs say it is correctly delivered via Dovecot, but the Sieve script says it can not find the folder "Public/.office". As a consequence, Dovecot creates a new Maildir in /var/mail/mydomain.com/office and delivers the mail there instead of saving it in the correct directory (/var/mail/mydomain.com/public/.office). Is there something I set incorrectly in my configuration? What is causing Dovecot not to recognize the correct mailbox during delivery? Is there a way to list all mailboxes seen by dovecot-lda itself?

Allowing a sender control over both the recipient (via spoofing), and the content seems like perfect recipe to turn your mail server into a spam relay cannon. If you do do this, you should hedge this by only allowing it from known trusted senders (e.g. local network). Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Dovecot crashes on large search result sets in virtual folders when using fts-solr
by Steffen Templin 19 Mar '14

19 Mar '14

Hi Devs, I experience reproducible crashes when searching in a virtual folder with fts-solr activated. The crashes occur only, if the folder contains a large number of mails and the result set of the search is also large. If the result set is small, no crash occurs. This happens on Debian Wheezy with versions 2.1.7 and 2.2.9. My goal was it to setup the possibility for cross-folder fulltext search. Therefore dovecot was setup with fts-solr, which seems to work fine in most cases. A virtual folder "test" in a namespace "virtual" was created and configured to return all mails from all mailboxes in the default namespace (with empty prefix). It was configured like this: /etc/dovecot/virtual/test/dovecot-virtual: * all It's also reproducible with: INBOX all The test user only has the standard mail folders (Sent, Drafts, Trash) beside the INBOX and of course the folder "virtual.test". INBOX contains about 10.000 mails, the other folders are empty. "virtual.test" correctly referrs to all mails of the INBOX. Searching within the INBOX returns the desired results without any problems. Performing the same search within "virtual.test" fails and dovecot crashes. However, if the result set is small, no crash occurs. My test mails are imported from the ubuntu mailing list. Therefore the term "ubuntu" produces a large result set. See attachments for further details, they all refer to the same crash, reproduced with version 2.2.9 (from the Debian Backports repository): - config.txt: dovecot -n - gdb_backtrace.txt: The gdb backtrace of the attached core dump - log.txt: A logfile extract from the crash - protocol_output.txt: The telnet session that caused the crash Don't hesitate to ask for further details. Thanks and best regards, Steffen

[Dovecot] versioning of mailbox index files
by morrison 18 Mar '14

18 Mar '14

Hi, I am wondering if dovecot assigns version information in mailbox index files so that by which version of dovecot the index files are created can be determined. Our existing mail service used dovecot 2.2.4 with lots of active mail users. When upgraded to 2.2.10, imap processes aborted all the time due to the corrupted index files (the problem was fixed in dovecot 2.2.5). After investigation, I found that this annoying problem could be avoid by deleting index files before opening a mailbox. Now the problem is how I could know if the index files are created by a version newer than 2.2.4. Thanks, Morrison

[Dovecot] FTS solr : body search gives mysql error
by Alexandre Ellert 15 Mar '14

15 Mar '14

Hello, I've recently setup FTS solr plugin, following http://wiki2.dovecot.org/Plugins/FTS/Solr, and I have this error in logs when I do a body search : Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Warning: mysql: Query failed, retrying: Unknown column 'disableindexer' in 'where clause' Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Error: sql(user(a)domain.com): User query failed: Unknown column 'disableindexer' in 'where clause' Mar 13 01:46:40 mut-mx-1 dovecot: indexer-worker: Error: user user(a)domain.com: Auth USER lookup failed Mar 13 01:46:40 mut-mx-1 dovecot: indexer-worker: Error: User user(a)domain.com lookup failed: Internal error occurred. Refer to server log for more information. Mar 13 01:46:40 mut-mx-1 dovecot: imap(user(a)domain.com): Error: indexer failed to index mailbox INBOX Anyway, the search result seems good. Should I worry about this error or is there other thing I should do (i.e modify mysql schema) ? I'm using mysql as a backend to store users and password. According to the documentation, I just added this block of configuration (please tell me if need full doveconf -n) : mail_plugins = fts fts_solr [ my other plugins ] plugin { fts = solr fts_solr = url=http://127.0.0.1:8080/solr/ } Versions : OS : Debian 7 dovecot : 2.2.12 (from dovecot-ee repo) solr : 3.6.0 (from distrib repo) Other recommendations and feedback about using solr FTS in production would be greatly appreciated. Many thanks. Alexandre

[Dovecot] Strange difference between mails delivered with dovecot-lda and lmtp
by kjonca＠o2.pl 15 Mar '14

15 Mar '14

For a long time I have had configuration where mails were fetched by fetchmail then passed to exim and then passed to dovecot via lmtp. Recently I remove dovecot module and mails are passed from exim to dovecot via dovecot-lda Yesterday I have some kind of accident and lost my .fetchids file so a lot of mails were fetched again. During duplicate hunting I found something strange: messages fetched yesterday (passed to dovecot with lda have additional line) have additional line at the end: for example --8<---------------cut here---------------start------------->8--- diff cur/1392241092.M478532P15313.alfa,S=13668,W=13925:2,a cur/1394814438.M978438P14745.alfa,S=13567,W=13823:2,a 1,6c1,4 < Return-Path: <system(a)przelewy24.pl> < Delivered-To: <kjonca@localhost> < Received: from alfa.kjonca < by alfa.kjonca (Dovecot) with LMTP id p94PDcTp+1LROwAApvcrCQ < for <kjonca@localhost>; Wed, 12 Feb 2014 22:38:12 +0100 < Received: from [127.0.0.1] (port=60632 helo=alfa.kjonca) --- > Return-path: <system(a)przelewy24.pl> > Envelope-to: kjonca@localhost > Delivery-date: Fri, 14 Mar 2014 17:27:18 +0100 > Received: from [127.0.0.1] (port=45527 helo=alfa.kjonca) 9,10c7,8 < id 1WDhVU-0003ys-75 < for kjonca@localhost; Wed, 12 Feb 2014 22:38:12 +0100 --- > id 1WOUgz-00015z-L0 > for kjonca@localhost; Fri, 14 Mar 2014 17:10:41 +0100 13c11 < for <kjonca@localhost> (single-drop); Wed, 12 Feb 2014 22:38:12 +0100 (CET) --- > for <kjonca@localhost> (single-drop); Fri, 14 Mar 2014 17:10:41 +0100 (CET) 30c28 < Message-Id: <E1WDhVU-0003ys-75(a)alfa.kjonca> --- > Message-Id: <E1WOUgz-00015z-L0(a)alfa.kjonca> 256a255 > --8<---------------cut here---------------end--------------->8--- I'm somewhat confused with this.

[Dovecot] Problem with trying to use dsync with ldap userdb
by Frédéric Goudal 14 Mar '14

14 Mar '14

Hello, I'm trying to use dsync on a dovecot 2.2.12 I'm using an ldap database as a user database with the following configuration : auth_bind = yes ldap_version = 3 auth_bind_userdn = uid=%u,ou=People,dc=ipb,dc=fr user_attrs = uidNumber=uid,gidNumber=gid But I keet having the following errors : 2014-03-14 17:53:37 doveadm(XXX): Debug: user XXX: Auth PASS lookup returned temporary failure: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Debug: auth input: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Error: sync: /usr/local/var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set) I have been hunting through the doc for the last hours and I don't find what to change. I found something about adding set INSECURE_SETUID=1 export INSECUURE_SETUID before checkpassword-reply launch, but it does not change anything... Btw my two server have use the users uid from the ldap, but don't allow user login on the servers where only admin can log in. Does somebody has an idea where to dig ? f.g.
