[Dovecot] possible quota bug ?
by fernando.figaro＠uol.com.br 31 Mar '14

31 Mar '14

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] pop3 mailbox mirroring issues using dsync
by Nikolaos Milas 30 Mar '14

30 Mar '14

Hello, I have setup v2.2.12 to mirror mailboxes between our main mail server (vmail.example.com) and a failover server (vmail1.example.com) The problem I have is the behavior of mailboxes used on the main server (*vmail*) over POP3. I have setup an IMAP account on the failover server (*vmail1*) on such a mailbox: the mailbox is used on vmail using POP3 and the same is monitored on vmail1 using IMAP. It's mailbox *userx*(in Maildir format). I notice that all mail coming in userx mailbox on vmail, is correctly replicated on vmail1, but when it is downloaded from vmail over POP3 (and the mailbox there remains empty), the same mailbox on vmail1 is not updated to be emptied (automatically) as well, but it is accumulating mail forever (which is real problem on the mirror server). Is there a setting to enable correct mirroring of a POP3 mailbox (to empty the respective mailbox on the failover server) when mail is downloaded from it or something else should be done in this respect? Please explain. I quote below the full current config on the main server.

[Dovecot] basic dsync wrapper for migration from another server
by Alan McGinlay 29 Mar '14

29 Mar '14

Hi, I cobbled together this somewhat shoddy Bash script to migrate email accounts from our Cyrus server to a new dovecot system. Feel free to use, or laugh at it as you wish :) #!/bin/bash ## # Migrate email accounts via IMAP from one server to another ## trap "kill 0" SIGINT workdir=/root/migrate # Load list of users into array. The file "migration_map" should contain one user(a)domain.tld per line. mapfile userList < $workdir/migration_map # Number of symultanious migrations num=10 index=0 # Loop over the array of user accounts function process_userlist { procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) # Perform $num operations at a time for the length of the userList while [[ $procs -lt $num ]] && [[ ${#userList[@]} -gt $index ]]; do procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) dsync -o mail_fsync=never mirror -f -R -u ${userList[$index]} imapc:& echo "procs: $procs user: ${userList[$index]} index: $index" let index++ done } # Until the userList is empty, keep going until [ ${#userList[@]} -eq $index ]; do process_userlist done exit 0

[Dovecot] struggling with dovecot v2.2

Hello all, Long time, no write :-) I am building a spanking, wonderful new mail server. I am very excited about this, since I am going to use the new dovecot v2.2.12 !! However, last time I did this (and documented it), I was working with v1.2. I consulted my notes and it seems there are huge differences between v1.2 and v2.2. So my question is, would anyone know if there's a "quick start" guide for v2.2 ? tia, s.

That's usually the cause of many problems I see with log entries like yours.

I just want it to be reasonably secure > and simple. You'll need to know these things in order to understand the problem. The essential difference, as far as your concerned, is that TLS (or STARTTLS or SSLv(some-number-I-forget)) starts out in plain text, then the client issues a command (STARTTLS) to commence the secure (encrypted) communication handshake, whereas SSL dives right in and expects the client to negotiate SSL parameters immediately. These two variations of SSL listen on two distinct ports. If you get these cross up, you'll get the above error log. In my experiments: SSL client -> TLS server port: Aborted login (no auth attempts) TLS client -> SSL server port: client hangs, Disconnected: Inactivity (no auth attempts in 180 secs) SSL/TLS + clear-text password is secure. If you do not use SSL/TLS, you'll have to use CRAM-MD5 or some challenge-response authentication to defeat password snooping. You could use both, but that's overkill.

27 Mar '14

Hi, I am trying to setup dovecot replication based on: http://wiki2.dovecot.org/Replication All mailboxes share the same UNIX userid ('vmail'), and I setup ssh-key based login for this account in both directions. As LDA exim4 is configured to use dovecot deliver LDA. Here is the relevant config from exim: /usr/lib/dovecot/deliver -d $local_part -f $sender_address -a $original_local_part@$original_domain When a message is deposited to a mailbox, it does not get replicated. The log is silent: Mar 25 15:00:20 mx02 dovecot: master: Dovecot v2.2.9 starting up (core dumps disabled) Mar 25 15:01:05 mx02 dovecot: lda(user.name): msgid=unspecified: saved mail to INBOX The output from doveconf -n is attached. Any help is appreciated, Thanks, Milan.

[Dovecot] %{orig_user} missing in checkpassword-Script
by dovecot.pkoch＠dfgh.net 27 Mar '14

27 Mar '14

Hi everybody, I'm using SSL client certificates or checkpassword scripts to authenticate our users. If a user sent a client certificate from his smartcard my checkpasswort will ignore the password, if he does not sent a client certificate but uses his OTP-token then my checkwassword script will check wether the password is a correct one time password. My problem is: the AUTH_USER variable will either contain the username that was configured in the mailclient (if auth_ssl_username_from_cert=false) or the username from the certificate (if auth_ssl_username_from_cert=true). I would like to compare both values, i.e. the %{user} Dovecot-variable and the %{orig_user} Dovecot-variable. But the environment of a checkpassword-script has only one of them. Any ideas? I tried to change the source and found the routine where all the AUTH_xxx environment variables are created. But the %{orig_user] variable was empty at that point, so no AUTH_ORIG_USER variable is created. I'm afraight that whenever the %{user}-Variable is replaced by the UID from the client certificate (due to auth_ssl_username_from_cert=true), the original value of %{user} is NOT copied into %{orig_user} Can someone more familiar with the dovecot source check this please or give me a hint where to look further Kind regards Peter Koch

Re: [Dovecot] IMAP proxy with master user and CRAM-MD5 auth mechanism
by ML mail 26 Mar '14

26 Mar '14

Hi Trent, Thanks for your exhaustive explanation now it is clear. What was unclear to me was the fact that the IMAP proxy server has to take care of the authentication in this case of using a master user and therefore it needs access to the passwords (in my case stored in the mailbox table in PostgreSQL). I still have two open questions: 1) Do I really need the userdb on my IMAP proxy config as you mention in your mail? In my understanding the passdb should be enough (which in my case will use a SQL query joining the result of my proxy and mailbox tables). 2) Is this correct that the IMAP backend (the mailbox server) in this case scenario has to use PLAIN authentication and can NOT use CRAM-MD5? Regards,ML

[Dovecot] IMAP proxy with master user and CRAM-MD5 auth mechanism
by ML mail 26 Mar '14

26 Mar '14

Hello, I would like to know if it possible to have a dovecot IMAP proxy frontend where CRAM-MD5 can be used as auth mechanism (assuming I would be using a master user/password on the dovecot IMAP backend/mailbox)? I have read a few times the following http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy page but somehow it is still unclear to me if the IMAP proxy then needs to have all the users and passwords in its proxy table in the database? Unfortunately there are no examples for that case. Also with this case scenario is it possible to store the users' passwords in CRAM-MD5 format? Any pointers or documentation to such a scenario would be great. Thanks and regards M.L.

[Dovecot] Trying to get Centos5 set up with dovecot
by DCA 26 Mar '14

26 Mar '14

Greetings, It seems I'm having some trouble getting this message into the list. I have used this dovecot list before. I am trying to set up dovecot to replace an older POP3 server in an existing set up. Currently the server uses sendmail to handle incoming mail. users are in /etc/mail and their incoming eMail lands in the /var/mail/username in /var/mail the username file is owned by username:mail I have dovecot configured to create the imap folders in /home/username/mail/ on existing accounts login attempts fail with errors such as: chown /home/username/mail/.imap/INBOX failed: Operation not permitted egid=500(username), group based on /var/mail/username mkdir /home/username/mail/imap/INBOX failed: Operation not permitted. Everything seems to work as expected but only if I add "username" into the "mail" group OR if I have all mailboxes chowned to username:username Is there any way to tell dovecot to ignore the group ownership of /var/mail/username and focus instead on using username:username for everything in /home/username ? If I have to add every user to the mail group I can but this seems messy. Thanks!

[Dovecot] Direct groups of users to pairs of backend servers
by Murray Trainer 25 Mar '14

25 Mar '14

Hi All, I am using dovecot in the Director setup with multiple proxy and backend mailstores and user information stored in LDAP. I am aware users can be directed to a single backend server. It would be useful to be able to direct groups of users to pairs of backend servers to give some fault tolerance against NFS issues and make the whole thing more scalable. Otherwise each backend mailstore will need all the NFS mounts and the whole cluster will be affected if one NFS mount has an issue. I am not sure if this possible with the current dovecot implementation? If not it would be a great enhancement. Thanks Murray

[Dovecot] pb with setting quota_rule=backend quota=fs for quota-warning
by marion 25 Mar '14

25 Mar '14

Hello my config is debian wheezy with dovecot v.2.1.17-2., plugin quota /imap_quota is ok : I can read the real filesystem user quota for each different user with - doveadmin quota get - thunderbird - SOGo my problem is to configure quota-warning message : 1) if no quota_rule is defined then my dovecot-debug.log looks like Mar 25 18:28:02 imap(testuser): Debug:Quota warning: bytes=0 (80%) messages=0 ... 2) As soon as I set quota_rule = *:storage=1G , quota root is correctly defined, and quota-warning messages are sent according to the ratio I defined (cf below 90-quota.conf) with THIS limit (1G) , the same for all users and that’s not what I expect when I set individual quota... 3)And If define something like: quota_rule = * : backend (or backend=%q or …) dovecot definitively hangs with a) doveadm quota get -u testuser doveadm(testuser): Error: user testuser: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:backend: Unknown rule limit name: backend b) even my login in SOGo hangs /var/mail/mail.err Mar 25 21:56:22 biwa dovecot: imap(testuser): Error: user testuser: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:backend: Unknown rule limit name: backend Is there a way ( a variable ?) to link the real filesystem quota limit with the quota_warning process ? … something like quota_rule = *:storage=%VAR ? 90-quota.conf ------------------- plugin { quota_warning = storage=80%% quota-warning 80 %u quota_warning2 = storage=90%% quota-warning 90 %u } plugin { quota =fs } service quota-warning { executable = script /etc/dovecot/myconfig/quota-warning.sh unix_listener quota-warning { mode =0666 } } Thank you in advance best regards, Philippe ______________ Philippe Marion

[Dovecot] Getting second quota limit out of database
by dev＠stean.ch 25 Mar '14

25 Mar '14

Hello there, I am working with dovecot v2.2.12, and have setup a user and domain quota by using a quota/quota_rule for user and quota2/quota2_rule for the domain. This works fine when the limit configuration for both is stored inside dovecot configuration files. However, I would like to have the limits configurable on a user and domain base, and that data is stored inside my SQL database. Getting the user quota out of a database with SQL works fine, as documented with "SELECT whatever AS quota_rule FROM mytable", I extended my query to return quota2_rule too, but dovecot did not really do something with that value in the end, the domain limit was set to 0, as visible through the logs and with doveadm quota get ... Any idea or hint how I could get dovecot to read the limit for the domains out of my SQL database ? Thanks, Stephan

It's always the same "dovecot.index.cache" file and only for the same heavily used account. The account is currently used from about 10 different clients with imap at the sime time.

[Dovecot] Dovecot/Django authentication

We've got an application in django that has passwords stored in both sha1 and pbkdf2_sha256 form. We need dovecot to be able to authenticate against the django database (we can't modify django to store passwords in dovecot's form, I'm afraid). Has anyone done a dovecot authentication plugin to support these password forms (and/or any other forms that django supports)? Thanks- Tom

[Dovecot] Case-sensitive INBOX or client issue?
by SB Code Ninja 24 Mar '14

24 Mar '14

I am using dovecot as an IMAP server for a Cisco product (Cisco Agent Desktop by Calabrio) and noticed some odd behavior when trying to access emails. The mail is delivered to the main INBOX, then a Cisco server moves it to a directory within the INBOX based on the queue it is meant for. Here is the directory structure of the Maildir: Maildir/INBOX Maildir/INBOX/tmp Maildir/INBOX/63 Maildir/INBOX/63/tmp Maildir/INBOX/63/dovecot.index.cache Maildir/INBOX/63/cur Maildir/INBOX/63/cur/1395445673.M548066P32100.uc-util,S=6403:2, Maildir/INBOX/63/dovecot.index.log Maildir/INBOX/63/dovecot-uidlist Maildir/INBOX/63/maildirfolder Maildir/INBOX/63/new Maildir/INBOX/dovecot.index.cache Maildir/INBOX/cur Maildir/INBOX/dovecot.index.log Maildir/INBOX/dovecot-uidlist Maildir/INBOX/62 Maildir/INBOX/62/tmp Maildir/INBOX/62/dovecot.index.cache Maildir/INBOX/62/cur Maildir/INBOX/62/cur/1395445491.M591207P32114.uc-util,S=6380:2, Maildir/INBOX/62/dovecot.index.log Maildir/INBOX/62/dovecot-uidlist Maildir/INBOX/62/maildirfolder Maildir/INBOX/62/new Maildir/INBOX/new Email is delivered to INBOX then gets moved to INBOX/62 or INBOX/63. The desktop software is then supposed to read the email and process it. I did a packet capture of the conversation and saw the following: IMAP Response: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. IMAP Request: A0 AUTHENTICATE PLAIN IMAP Response: + IMAP Request: <redacted> IMAP Response: A0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in IMAP Request: A1 LIST "" Inbox/63 IMAP Response: A1 OK List completed.

[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

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

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

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.

[Dovecot] NFS not responding generates authantication crash
by bart 14 Mar '14

14 Mar '14

I am facing dovecot authentication problems caused by unresponding NFS server. If there is even short break in communication with NFS server keeping maildirs, the dovecot generates the avalanche of processes (dovecot/imap and dovecot/pop3). The real number of connections was about 50 and after the problems occurs it rises to 1000. After about 3 hours the limit of connections is filled up: dovecot: master: Warning: service(auth): client_limit (1000) reached, client connections are being dropped and next: imap-login: Warning: Auth process not responding, delayed sending greeting pop3-login: Warning: Error sending handshake to auth server: Broken pipe imap-login: Warning: Error sending handshake to auth server: Broken pipe When the mail storage was local there was no such problem. After moving to NFS storage the problem arised when trying to make backup with dump (we switched to rsync then) or now if NFS is not responding for a while. My dovecot conf for NFS is in accordane with: http://wiki2.dovecot.org/NFS mmap_disable = yes dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster mail_fsync = always mail_nfs_storage = no mail_nfs_index = no NFS shares are connected with no special parameters. Can something be done on dovecot configuration to prevent from generating those dovecot connections processes? Or is it the problem with NFS configuration? -- View this message in context: http://dovecot.2317879.n4.nabble.com/NFS-not-responding-generates-authantic… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] quota using wrong limits in user shared mailboxes
by Steffen Kaiser 13 Mar '14

13 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have setup a shared namespace to expose user's mailboxes to other users. That works well. Via ACLs users can access other users mailboxes. I have setup a quota for each user, that works well, too. The quota is tracked and new messages are denied, if the quota is exceeded. I do not find hints, if you need to setup something special for shared namespaces. http://wiki2.dovecot.org/Quota/Configuration shows how to track the quota and http://wiki2.dovecot.org/SharedMailboxes/Shared shows how to setup the namespace and ACL. If user1 shares "mailbox" to user2 and user2 copies a message there, the quota is tracked in the quota of user1 correctly. But to calculate if * LOGIN user2 ... * COPY 1 users.user1.mailbox fails with overquota or succeed, the quota limit of user2 is used instead of the quota of user1, whom "mailbox" belongs to. I have tested it with a. limit(user2) < limit(user1) b. quota(user1) + sizeof(message) < limit(user1) if quota(user1) + sizeof(message) > limit(user2), COPY fails with overquota. If I raise the quota of user2, the COPY succeeds. That means, although the target user's quota is not exceeded and won't after the copy, COPY fails. That seems to be wrong for me. The same will apply to the other way round, I guess: If the target user is over quota, but copying user's quota limit is greater than that, the COPY succeeds. [I have not tested it.] Hence, if you enable sharing, you undermine quota, because the other user can copy messages into a mailbox of an user overquota. Does other people see the same issue?

Hi There, Ive taken a look at this and cant quite figure out what is going on here. I have tested all the SQL permissions, and also changed the unix_listener auth-userdb mode to 0666 (as instructed elsewhere to try and solve this issue), but cannot seem to work out what the issue is. Would someone be able to please point me in the correct direction here?

[Dovecot] Turning on autocreate of maildirs - how?
by Graham Leggett 13 Mar '14

13 Mar '14

Hi all, I have a dovecot v2.2.7 installation, and I would like dovecot to autocreate the Maildir mailbox when those mailboxes don't exist. Following the instructions at http://wiki2.dovecot.org/MailboxSettings have had no effect, the errors below are reported. As soon as I create the Maildir manually with maildirmake fetching mail starts working fine, so all of the messages about the directory being ambiguous seem to be a red herring. Anyone know how to turn this on?

[Dovecot] Struggling with antispam
by Alan Chandler 13 Mar '14

13 Mar '14

I have a dovecot installation I am building on a raspberry pi for a mail server for the home. I am almost there, everything bar one thing is working. In simple terms dovecot is the authentication agent and the lda (using lmtp) for postfix. My maildir mailboxed at at /var/mail - location and accounts controlled by a small sqlite database. the uid for these mailboxes are 10001 and up and are not mapped to any account on the system. The sieve plugin is working and I have a default script which works to archive outgoing mail, returned via postfix sender_bcc_maps to user+saveout into a Sent subfolder organised by date. postfix also uses milters, to do spf, and dkim checking - and most importantly from this posts perspective passes all mail through dspam, adding an X-DSPAM-Signature header as it passes through. I plan to use another default sieve script to move mail based on the X-DPAM-Result header to move messages to the users Junk folder (when I can get antispam working). I want to use the antispam plugin to pick up users moving mail in and out of their Junk folder to train dspam. I initially tried using antispam's dspam backend. However I could not get it to work. I "think" the issue is that antispam is running with uid 10001 when it does this, and dspam will not process the message because it can't find this uid as a system user. But I am not sure. The approach I am trying now, is use the pipe backend to send mail to spam(a)chandlerfamily.org.uk or ham(a)chandlerfamily.org.uk - and via postfix manipulations get that to call dspam as user dspam. If I run as root and use sendmail -bv to check that it works I get a delivery report that shows that it would indeed arrive at dspam I have a file in /var/spool/dspam called group which has dpsam:shared:* In it so that all users share the same dictionary. However, when I try to make this work with anitspam, I keep getting failure, and I can't work out what is causing it. Maybe its again because I am running with uid 10001 when calling sendmail but I don't know. antispam config is plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash = Trash antispam_spam = Junk antispam_pipe_program=/usr/bin/sendmail antispam_pipe_program_args=-f;dspam(a)chandlerfamily.org.uk antispam_pipe_program_spam_args=spam(a)chandlerfamily.org.uk antispam_pipe_program_notspam_args=ham(a)chandlerfamily.org.uk } And what appears in syslog as a result of moving a mail from my INBOX to the Junk folder in thunderbird is ...

I would prefer to use dpsam backend directly if someone can tell me how to overcome the dspam rejection issues, but this alternative would also work (if a bit more convoluted to get mail to the correct place) if I could get antispam to call sendmail correctly.

[Dovecot] Disable/patch iOS7 Full Body Search
by Chris Laif 12 Mar '14

12 Mar '14

As mentioned in other posts [1], iOS7 Mail App uses a multi-folder full body search by default. As to my knowledge, this behavior cannot be disabled within the Mail App. Is there any way to disable/patch this behavior on the server side? My users complain that searching now takes 'forever'. They were happy with the old behavior (searching From/To/Subject only). I do NOT want to setup/maintain a dovecot FTS. I just want to have the 'old' behavior. Chris [1 ]http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body-searches-by-default/ ("Our plan at FastMail is to detect iOS clients, and convert all searches into FUZZY searches.")

[Dovecot] Finding memory leaks
by Philipp Brüll 12 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I try to find a memory leak in a dovecot plugin that I develop. In order to find it, it would be helpful to print the total amount of memory that is currently allocated. This print could than spread over the source code and the memory consumption can be tracked. I've tried i_debug("pool size %u", (unsigned int)pool_alloconly_get_total_alloc_size(system_pool)); But that failed. Does someone has a good advice? I would like to avoid complex solutions like valgrind.

[Dovecot] Doveadm?

I have a question? Is it possible that with doveadm delete all but the last x-number of messages in a folder. For example to retain the last 200 messages in the folder. If it is possible, how do you do it? Something like "doveadm expunge -u jane.doe(a)example.org mailbox xxx" Thank you! -- //Tommy

[Dovecot] Can I create multiple sockets and listen on them in parallel.
by Alan Chandler 11 Mar '14

11 Mar '14

I currently have a setup which is postfix -> dovecot via lmtp over a unix socket. The socket is located at /var/spool/postfix/private/dovecot-lmtp I am calling dspam as a milter from postfix. However I am struggling with getting dspam knowing the correct user for the incoming mail, because after its been through the milter, the virtual alias maps etc end up turning it into my "dovecot" user name, and the two are not easily comparable. So instead I want to try and set up postfix->dspam->dovecot But I want to take it in easy stages, and therefore ideally would like to set up dovecot to listen on two sockets simultenously = one for the existing connection from postfix, and one for the future connection from dspam - preferably in the context of the /var/spool/dspam or /var/lib/dovecot directories That way I can continue to receive existing mail whilst sending a few test mails through dspam. Does 10-master.conf config file work that way? (debian configuration) can I change something like this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } } into this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } unix_listener /var/spool/dspam/dovecot-lmtp { mode = 0600 group = dspam user = dspam } } and still have dovecot work? -- Alan Chandler http://www.chandlerfamily.org.uk

[Dovecot] POP3 and mail retention
by Roman Gelfand 11 Mar '14

11 Mar '14

Using outlook 2010 as mail client, I have noticed that once an email is moved from inbox, it is deleted from the cur/ directory on the server. Is there a pop3 setting on dovecot that would keep emails, with possible retention period, and recognize that this email has been moved from inbox, etc.. If all of this is doable, would setting outlook to delete the email after 14 days work? delete email from the server when emptying deleted folder? Thanks in advance

by Balamurugan Ramasamy 10 Mar '14

10 Mar '14

Hi All I follwed the steps in the below url to configure a dovecot proxy instance. http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I created a new file '95-test.conf' in /etc/dovecot/conf.d/ location. and put the below lines in that file. proxy=yes host=**** port=143 nopassword=yes However I am getting the following when starting the serice. I tried 'proxy' and 'proxy_maybe' entries, and they both failed. doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-auth.conf line 11: Unknown setting: proxy Could anyone help me how i can resolve this? Thanks Bala

[Dovecot] Sieve/autosubscribe subfolder
by Moritz Augsburger 09 Mar '14

09 Mar '14

Hi, I just ran across the annoying issue, that with lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes set, parent folders of newly created subfolders get subscribed without being existent. Let me give an example: In sieve I use fileinto "foo/bar"; but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets created, but without "foo/" being a Mailbox. Nevertheless gets "foo/" subscribed, so that I have a non-existing mailbox in my subscription list, what confuses thunderbird. So, to solve this problem, I would propose - either the implicit creation of foo/ as mailbox or - not subscribing foo/ Moritz

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file. If we manually remove the offending extra characters from the beginning of the file everything is working again, but often the same user will show the problem again tomorrow. However it's very rare and so far we haven't been able to reproduce the problem. After activating the mail_log plugin hoping it'll help us locate the problem we run across this case : The user (let's call him user(a)domain.gr) logs in via pop3 and deletes some mails but one of them fails: Jun 19 11:09:18 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.40, mpid=1389, secured, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:18 director5 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20670, msgid=<9f5b1a20a9428ed31a9e7e42ce4411f08d0.20130612070424(a)mail84.us2.rsgsv.net>, size=36526 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20671, msgid=<b27d72dc5a47a3235a232494c6fe8aa0(a)newsletter.stockout.gr>, size=4637 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20672, msgid=<1113670779560.1111910791405.1470.2.32032003(a)scheduler.constantcontact.com>, size=38655 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20673, msgid=<83600a274c1407c5aa4c263e2592cb54(a)debop.gr>, size=1181688 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20674, msgid=<F2A59BE7-007A-4567-9BA5-803446C3D7F8(a)bernier-eliades.gr>, size=61116 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Next message unexpectedly corrupted in mbox file /var/mail/K/Y/V/domain_gr_user_007 at 1 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Cached message offset 1 is invalid for mbox file /var/mail/K/Y/V/domain_gr_user_007 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=2/1502843, del=122/359, size=137448432 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Warning: Our dotlock file /var/mail/K/Y/V/domain_gr_user_007.lock was deleted (locked 9 secs ago, touched 9 secs ago) Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Error: file_dotlock_delete() failed with mbox file /var/mail/K/Y/V/domain_gr_user_007: No such file or directory Jun 19 11:09:27 director5 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 83.235.173.26 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> However he's still able to log in again : Jun 19 11:11:36 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.40, mpid=10094, secured, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:36 director3 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:51 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=0/0, del=0/237, size=75036938 Jun 19 11:11:51 director3 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 85.74.231.10 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> A few minutes later he receives another mail which is delivered with no problem : Jun 19 11:30:39 corvus amavis[546]: (00546-22) Passed CLEAN, [91.190.168.40] [91.190.168.40] <tk-14439(a)free.splio.com> -> <user(a)domain.gr>, Message-ID: <58175-bWFyaW5hQGJlcm5pZXItZWxpYWR lcy5ncg==(a)free.splio.com>, mail_id: J1P-0WpmQksJ, Hits: 1.412, size: 9025, queued_as: 02BA4AE00414, Tests: [DKIM_VALID=-0.1,DKIM_VERIFIED=-0.1,FREEMAIL_FROM=0.001,HTML_IMAGE_RATIO_04=0.61,INVALID_MSGID=1,URIBL_BLOCKED=0.001], autolearn=disabled, 1533 ms Jun 19 11:30:39 corvus smtp/smtpd[1283]: proxy-accept: END-OF-MESSAGE: 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 02BA4AE00414;

[Dovecot] Planning migration
by Alan Chandler 08 Mar '14

08 Mar '14

I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user. I looked at this page in the wiki http://wiki2.dovecot.org/Migration/Dsync but I am totally confused. 1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding 2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki

[Dovecot] How to run a program with mail_filter plugin
by Stanislas SABATIER 07 Mar '14

Hi, I'm using mail_filter plugin but I don't want it to launch a script but a program I wrote instead. In 10-master, if I put the absolute path to my program in the plugin settings ie : (…) service mail-filter { executable = /usr/local/bin/mail/my_email_filter (…) But I've got the following error from Dovecot : dovecot: master: Error: service(mail-filter): Initial status notification not received in 30 seconds, killing the process h ow do I need to configure the service to launch my program ?

[Dovecot] no sieve with lmtp_save_to_detail_mailbox=yes
by Dennis Kuhn 06 Mar '14

06 Mar '14

i have a problem with sieve and lmtp_save_to_detail_mailbox = yes. If the mailbox "detail" exists everything works fine, but if the mailbox detail does not exist then sieve does not work. The .dovecot.sieve.log file says sieve: info: started log at Mar 06 14:28:47. error: msgid=<531877EE.7070806(a)heinlein-support.de>: failed to store into mailbox 'test2': Mailbox doesn't exist: test2. I think this is the reason why no sieve script is executed, but why is sieve here involved? Is there any relation between lmtp_save_to_detail_mailbox=yes and sieve or is this a bug? The same sieve file works with the same mailaddress without mailextension, so the sieve script is not the reason for the failure.

[Dovecot] Still no emails since Feb. 6
by Steve Campbell 06 Mar '14

06 Mar '14

I checked my settings on the dovecot mailman page, and although my account was set to "disable" email, after changing it and attempting to have the list resend my password, I'm still not seeing emails. The last time I received emails, the outgoing server for the list was sent from the IP 193.210.130.67. Is that still correct? I've checked my logs to see if there's anything blocked, and I don't see anything. I've checked my access file and firewall, and nothing is blocked there. I'm not sure why my account settings showed "disabled", but it sounds like email was either bounced back to the list or my server is in some type of outgoing list to prevent sending to me. I'm at a loss. Is there any way an admin can check for me, please, to see if there's a problem they might spot? Thanks, steve

[Dovecot] Pigeonhole Sieve Extprograms Plugin
by dovecot＠voidptr.de 06 Mar '14

06 Mar '14

Hi, I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which should contain the "sieve_extprograms" plugin and thus also the vnd.dovecot.{pipe,filter,execute} capabilities. However when I add require "vnd.dovecot.filter"; to my sieve script via managesieve, the server reports error: require command: unknown Sieve capability: 'vnd.dovecot.filter' What am I missing and what should I do to get pipe/filter/execute to work? postconf -n attached.

[Dovecot] whole user mailbox read only
by Francesco 06 Mar '14

06 Mar '14

Hello, i was browsing the dovecot wiki for some documentation related to the use of ACLs but i couldn't find an answer. i'm in the need to prevent users from deleting emails, yet being able to add new content via imap, what i mean is that a user should be able to create an email in its mailbox (maildir actually is used), but once the email is there the user shouldn't be able to delete it. do you know if there is a way to accomplish this for each subfolder on a Maildir environment? Thanks in advance Francesco

[Dovecot] Shared Namespace and correct location
by Dieter Knopf 05 Mar '14

05 Mar '14

Hello again, i still have problems using a Shared Namespace in my configuration. I'm using Dovecot 2.2.9. mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INDEX=/home/vmail/%d/%n/INDEX/ namespace inbox { type = private separator = / prefix = inbox = yes } This works create. But: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/vmail/%%d/%%u/MAILDIR/shared:INDEX=/home/vmail/%d/%u/INDEXS/%%u subscriptions = no list = children } I'm still not sure how i can see a shared mailbox on a different account. I can add ACL rules and dovecot is adding SQL-Entries to the user-shares table. The dovecot-acl-list file is created too, hope this is okay (vfile + SQL) But i can't see the shared folder on the target account. I tried many location-pathes, but not sure how i can add the right folder. There must be a problem with %%d and %%u. Thank you very much, Dieter

[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext
by Traiano Welcome 05 Mar '14

05 Mar '14

Hi List I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes). I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration. My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time? Dovecot version: 1.0.7 (from dovecot-1.0.7-7.el5_7.1 rpm) The output of dovecot -n is: --- # 1.0.7: /etc/dovecot.conf info_log_path: /var/log/dovecot.debug verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~:INBOX=~/Mailbox mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 --- My dovecot.conf is as follows: ------ info_log_path = /var/log/dovecot.debug verbose_ssl = yes mail_location = mbox:~:INBOX=~/Mailbox mail_debug = yes protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } } dict { } plugin { } --- Many thanks in advance!

[Dovecot] Using AD, one more try - "successfol auth" and crashing auth process
by Jeroen Scheerder 05 Mar '14

05 Mar '14

Hi, I have no success in using AD with dovecot. The little checkpassword script I cooked up that uses ldapsearch to lookup a user DN (with an authenticated bind) and then ldapsearch with an authenticated bind for that DN again works well. * Approach 1: use a service account to bind to AD, lookup the user DN, and bind to that DN. It fails. The LDAP config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes dn = CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net dnpass = suppressed pass_attrs = sAMAccountName=user pass_filter = (&(objectClass=person)(sAMAccountName=%u)) user_attrs = sAMAccountName=user user_filter = (&(objectClass=person)(sAMAccountName=%u)) What happens in this case is best shown in the packet capture as displayed by tshark: $ tshark -o tcp.check_checksum:FALSE -tr -r dc2.pcap 1 0.000000 172.17.50.13 -> 172.17.10.2 LDAP 197 bindRequest(7) "CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net" simple 2 0.001879 172.17.10.2 -> 172.17.50.13 LDAP 88 bindResponse(7) success Yay! The service account binds just fine. 3 0.001967 172.17.50.13 -> 172.17.10.2 LDAP 180 searchRequest(8) "dc=office,dc=on2it,dc=net" wholeSubtree 4 0.002772 172.17.10.2 -> 172.17.50.13 LDAP 502 searchResEntry(8) "CN=Jeroen Scheerder,OU=Users,DC=office,DC=on2it,DC=net" \ | searchResRef(8) | searchResRef(8) | searchResRef(8) | searchResDone(8) success 5 0.098367 172.17.50.13 -> 172.17.10.2 TCP 66 49416 > 389 [ACK] Seq=246 Ack=459 Win=1037 Len=0 TSval=602425599 TSecr=124473537 Yay!

The user DN bind works. But wait, why is it taking dovecot 225 seconds to get around to trying it? The auth process has already given up. * Approach 2: A template defines the user DN. Bind to that DN. AD DNs don't contain usernames, but AD allows all kinds of non-LDAP shorthands for DNs, inclusing %user%@domain. I've verified this to work using ldapsearch: $ ldapsearch -o ldif-wrap=no -x -LLL -E pr=200/noprompt -H ldap://dc2.office.on2it.net \ -b dc=office,dc=on2it,dc=net -s sub \ -D js(a)office.on2it.net -W \ '(&(ObjectClass=person)(sAMAccountName=js))' DN Enter LDAP Password: dn: CN=Jeroen Scheerder,DC=office,DC=on2it,DC=net The config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes auth_bind_userdn = "%u(a)office.on2it.net" pass_attrs = sAMAccountName=user user_attrs = sAMAccountName=user What happens in this case is best shown by a snippet of dovecot logging: Mar 5 09:57:36 <mail.err> ponyboy dovecot: auth: Error: ldap(js,127.0.0.1,<z1dLNtjzJwB/AAAB>): ldap_search(base=dc=office,dc=on2it,dc=net filter=(&(objectClass=posixAccount)(uid=js))) failed: Operations error Mar 5 09:57:36 <mail.err> ponyboy dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=7247 client-id=1) Mar 5 09:57:36 <mail.crit> ponyboy dovecot: auth: Fatal: master: service(auth): child 7245 killed with signal 11 (core not dumped - set service auth { drop_priv_before_exec=yes }) Mar 5 09:57:36 <mail.info> ponyboy dovecot: imap-login: Internal login failure (pid=7247 id=1) (internal failure, 1 successful auths): user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=7248, secured, session=<z1dLNtjzJwB/AAAB> I find this intriguing -- "1 successful auths", so says imap-login, with auth dying horribly. I smell a rat. Something's wrong here...

[Dovecot] Send and Bounced mail not appearing, depending on mail client
by Dominique 05 Mar '14

05 Mar '14

Hi, I just installed Dovecot2 on Ubuntu 12.04 server with postfix and postfixadmin. I am using virtual users and virutal domains. When using Thunderbird, Roundcubemail,iOS mail application on an iPad2 or Kmail n Android, all mail sent and bounce shows up. However, when using vTigerCRM to send mails, nothing shows up - anywhere. I know the mail are being send - as per the mail.log and the various postfix log lines. But none of that is being captured by Dovecot... What am I missing? Thanks for any hints you can provide.

This does not test what you want, which is trying to authenticate the master user, not the regular user. From what I remember of your config, you have another passdb which holds the credentials of your master user: you need to check that file to make sure the master user's password (hash) matches what you think the master password ought to be.

[Dovecot] Hidden virtual folder
by Moritz Augsburger 04 Mar '14

04 Mar '14

Hi, I wanted to create a virtual folder containing all unread messages and the threads they belong to, and this config works really fine: > dovecot.conf: namespace { type = private prefix = virtual/ separator = / location = virtual:~/Maildir/virtual:INDEX=MEMORY list = children subscriptions = no } > virtual/All/dovecot-virtual: * -Trash -Trash/* -Junk -Junk/* -Drafts -Drafts/* -virtual -virtual/* all > virtual/New/dovecot-virtual: virtual/All inthread refs or unseen recent The only problem I got is that scanning all files for the virtual/All mailbox takes too long, and I would like to keep them cached (no INDEX=MEMORY), so I thought I'll just put virtual/All inside a second virtual namespace. As it's a bad idea to open the All directory manually, I could also hide the complete namespace to the user. So I added the following to my config: namespace { type = private prefix = virtual-all/ separator = / location = virtual:~/Maildir/virtual-all/ hidden = yes list = no subscriptions = no } But sadly it didn't work, a directory virtual-all/ pops up inside my client (thunderbird/icedove). Is hidden=yes/list=no unsupported for virtual locations, or is it me misconfiguring dovecot? If it should matter, it's version 2.2.9, or more specific debian 1:2.2.9-1~bpo70+1. Thanks Moritz

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings. Refer to server log for more information. There is a homedirectory and the permissions are set like on all other accounts.

[Dovecot] Dovecot, AD and authenticated binds...
by Jeroen Scheerder 03 Mar '14

03 Mar '14

I posted earlier with reports of less than stellar success in using Active Directory for dovecot authentication. My approach is to using the two-step approach of - obtaining the user DN by a search using an authenticated bind (using a service account) - then binding as that DN, and returning the relevant user attributes This hasn't been succesful. Dovecot's authentication process does perform the (first) authenticated bind successfully, it does obtain the right DN, than just sits there doing nothing as far as I can tell, and after a long delay concludes authentication failure - shortly before deciding to perform the bind with the user-supplied credentials, successfully. Source inspection has not resulted in a glorious eureka yet. So I thought, why not handle it myself? And I wrote a little script, using the checkpassword interface. I've enclosed it. The script is based on <http://wiki2.dovecot.org/AuthDatabase/CheckPassword>, but somehow the userdb_uid and userdb_gid I've passed back in the "EXTRA" environment variable get lost along the way. It syslogs, and the syslogs show that the LDAP parts working as expected: Mar 3 14:49:09 <mail.info> ponyboy checkpassword: successful authenticated bind and DN(js) lookup Mar 3 14:49:09 <mail.info> ponyboy checkpassword: DN(js) is CN=Jeroen Scheerder,OU=Users,OU=Netherlands,OU=ON2IT,DC=office,DC=on2it,DC=net Mar 3 14:49:09 <mail.info> ponyboy checkpassword: js authenticated In dovecot's log, simultaneously, I see basically a successful login, except that the (user_)uid and (userdb_)gid work - unless I disable prefetch, and use a static userdb: Mar 03 14:49:04 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Mar 03 14:49:04 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 03 14:49:04 auth: Debug: auth client connected (pid=90856) Mar 03 14:49:09 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=+qFODbTzDgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=63246 resp=<hidden> Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): execute: /usr/local/etc/dovecot/checkpassword-on2it /usr/local/libexec/dovecot/checkpassword-reply Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): Received input: userdb_uid=143 userdb_gid=143 Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): exit_status=0 Mar 03 14:49:09 auth: Debug: client passdb out: OK 1 user=js Mar 03 14:49:09 auth: Debug: master in: REQUEST 4007395329 90856 1 29571963894e557ab643d2e51872ba55 session_pid=90899 request_auth_token Mar 03 14:49:09 auth: Debug: prefetch(js,127.0.0.1,<+qFODbTzDgB/AAAB>): success Mar 03 14:49:09 auth: Debug: master userdb out: USER 4007395329 js uid=143 gid=143 auth_token=e2d7c2463dd4c039010e904afb4ea45214cb7de5 Mar 03 14:49:09 imap-login: Info: Login: user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=90899, secured, session=<+qFODbTzDgB/AAAB> Mar 03 14:49:09 imap: Error: user js: Mail access for users with UID 143 not permitted (see first_valid_uid in config file, uid from userdb lookup).

[Dovecot] Tracking logins
by Alex 03 Mar '14

03 Mar '14

Hi, I'm using dovecot-2.1.17 on fc18 and wondered if there is some mechanism, perhaps a database, that can store the logins/logouts for each user? I realize there's something already logged to syslog, but I'd like more of a history. While lastlog is great for users that actually login, my dovecot users don't login, just check email via pop and imap. Any ideas greatly appreciated. Thanks, Alex

[Dovecot] maildir quota divergence
by Juan Carlos Sanchez 03 Mar '14

03 Mar '14

Hello; We are using maildir quotas and have found differences in many users in respect to what system command are showing and doveadm quotas. For example, four user test, we have: doveadm quota get -u test Quota name Type Value Limit % STORAGE 98066 102400 95 MESSAGE 883 - 0 But if we check user mail_location with "du" system command we get he is using 70458 Kb. We are running dovecot 2.1.17 ¿any clue? Thanks in advance.

[Dovecot] No speed improvement with FTS for iOS 7?
by Nicholas Riley 02 Mar '14

02 Mar '14

Hi, I recompiled Dovecot with Lucene FTS to try to improve iOS 7 IMAP search speed. Unfortunately this does not seem to help. I have 60 mailboxes, totaling 300 MB; lucene-indexes is 30 MB in size. % doveadm mailbox status -t all '*' messages=16335 recent=0 unseen=1736 vsize=280049586 Searching for a single word which is present in two messages of one mailbox takes 40 seconds to return. This is true whether or not fts is enabled. doveadm search takes much less than 1 second to do the same search. % time doveadm search BODY cython d8f09230c97af952b60c0000c1443b93 1 d8f09230c97af952b60c0000c1443b93 2 doveadm search BODY cython 0.18s user 0.05s system 99% cpu 0.230 total With fts disabled, it takes about 6.5 seconds. This is still a long way from 40 seconds. Is there any way I can make dovecot perform better here? Thanks, -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] + prefix in dovecot-virtual
by Nicholas Riley 01 Mar '14

01 Mar '14

Hi, The "+" prefix in dovecot-virtual does not seem to be documented. only discovered it because I tried to include a mailbox whose name began with + and Dovecot gave me an error when I tried to copy to it. I see it was added here: http://hg.dovecot.org/dovecot-2.2/rev/be0f0de75e34 My dovecot-virtual file looked like this: !+/2014-03 +/2014-02 all I just added another + to the second line and it seems to work. I don't care about \Recent thankfully but is there a better way to specify a mailbox whose name begins with +? Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Force SSL authentication per user basis
by Urban Loesch 28 Feb '14

28 Feb '14

Hi, I'm searching a way to force encrypted connections for POP3/IMAP on a per user basis. To not break clients which still connect in plaintext (there are still many of it) I must implement a mechanism to force encrypted connections on a per user basis. The users and passwords are stored in a mysql database. So there would be no problem to expand the database with a column like "ssl_tls" -> yes/no. The problem now: how can I get dovecot to process this field in the right way? I searched the list and googled about such a way, but I can't find any solution. My Dovecot version is 2.2.12. Many thanks and regards Urban Loesch

[Dovecot] Logging authentication failures when Dovecot's auth service used to authenticate postfix smtpd
by MV 28 Feb '14

28 Feb '14

Hello, tl;dr: Is there a way to get dovecot's auth to log failed smtp authentications without having to switch on "auth_verbose"? postfix version 2.11.0 and dovecot version 2.2.12 I'm currently migrating my postfix+courier to postfix+dovecot and so far it's working as expected. Except for logging smtp login failures. Despite Postfix logging successful authentications (see sample below), it doesn't log failed smtp logins. Feb 25 22:28:53 mailer2 postfix/submission[20274]: C981B20198: client=A-B-C-D.*****.net[A.B.C.D]:63107, sasl_method=PLAIN, sasl_username=joe(a)example.net And since my postfix setup authenticates virtual users through Dovecot's auth, I thought maybe dovecot could report smtp login failures the same way it reports imap and pop3 login failures. Below is a sample extracted from "info_log_path" after several imap and pop3 login failures. (Obviously the IP 255.... is made up and irrelevant for this mater). # begin extract "/var/log/dovecot-info.log" 2014-02-27 21:14:26 auth: Info: passwd-file(joe(a)example.net,255.255.255.255,<Y0lbzmnzfwAuQV80>): Password mismatch 2014-02-27 21:16:46 auth: Info: passwd-file(foobar,255.255.255.255,<Y0lbzmnzfwAuQV80>): unknown user 2014-02-27 21:52:00 auth: Info: passwd-file(foo(a)example.net,255.255.255.255,<0Su6VGrzGwAuQV80>): unknown user 2014-02-27 21:53:35 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Empty username 2014-02-27 21:53:55 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Username character disallowed by auth_username_chars: 0x5c (username: \0) 2014-02-27 22:08:05 auth: Info: plain(?,255.255.255.255): invalid input 2014-02-27 22:09:36 auth: Info: passwd-file(joe(a)example.net,255.255.255.255): Password mismatch 2014-02-27 22:09:53 auth: Info: login(?,255.255.255.255): Empty username # end extract I've tried adding "-L -o info_log_path=/var/log/dovecot-info.log" to the both auth and auth-worker services but that yield nothing. ----------------------%<-------------------------------- auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/virtual_users driver = passwd-file } userdb { args = username_format=%u /etc/dovecot/virtual_users default_fields = uid=vmail gid=vmail driver = passwd-file override_fields = home=/home/vmail/%d/%u result_failure = return-fail result_internalfail = return-fail } service auth-worker { executable = auth -w -L -o info_log_path=/var/log/dovecot-info.log } service auth { executable = auth -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix user = postfix mode = 0660 } } service lmtp { executable = lmtp -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix mode = 0660 } } ---------------------->%-------------------------------- The relevant postfix config is ... smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth virtual_transport = lmtp:unix:private/dovecot-lmtp

[Dovecot] Dovecot2 vs. AD, "Inactivity during authentication"
by Jeroen Scheerder 28 Feb '14

28 Feb '14

Hi, I'm trying to setup Dovecot2 for o IMAP client access o LDA for postfix mail delivery (with SIEVE) ... on a FreeBSD host. The FreeBSD server has no users (by intention), so I've set up a virtual mail domain, using LDAP lookups in Postfix. So far so good. Mail delivers into the proper mailbox. But I'm stuck getting Dovecot to authenticate. User- and passwd DB's are set up for LDAP lookups to AD, using an authenticated bind (the AD server offers no anonymous binds, yet). I've enabled all the debugging I can find, but my logs have little information to offer. Any help in getting me a step further would be much appreciated. In particular, I'd like to learn how do diagnose these userdb/passdb issues properly. Here's what I see in the logs: Feb 27 12:25:49 <mail.info> ponyboy dovecot: imap-login: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 172 secs): user=<>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<r/ERi2HzQAB/AAAB> Feb 27 12:26:42 <mail.err> ponyboy dovecot: auth: Error: PLAIN(js,127.0.0.1,<r/ERi2HzQAB/AAAB>): Request 74099.1 timed out after 225 secs, state=1 This logging is related to the folloging IMAP session: ponyboy% telnet localhost 143 Trying 127.0.0.1...

Following this guide: http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ I can't seem to get it to work, as soon as I add the smtpd_recipient_restrictions setting to postfix I can no longer send mail at all. I get the message SMTP Error (450): Failed to add recipient "postmaster(a)example.com" (4.7.1 : Recipient address rejected: Internal error occurred. Refer to server log for more information.). I googled around and found this command to test the quota-status service: printf "recipient=postmaster at example.com\nsize=1234\n\n" | nc 127.0.0.1 12340 It seems to always return the quota_status_nouser message. I'm really stumped here. What logs do I need to check for errors and does anyone have any experience with this? I'm running Dovect 2.2.10 with Postfix 2.6.6 Here's my dovecot -n result: # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.5.1.el6.x86_64 x86_64 CentOS release 6.5 (Final) auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf } first_valid_uid = 2000 last_valid_uid = 2000 listen = * log_path = /var/log/dovecot.log mail_gid = 2000 mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_plugins = quota mail_uid = 2000 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 = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/%%Lh/Maildir/:INDEX=/%%Lh/Maildir/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } passdb { args = /etc/dovecot/dovecot-master-users-password driver = passwd-file master = yes } plugin { acl = vfile acl_shared_dict = proxy::acl auth_socket_path = /var/run/dovecot/auth-master autocreate = INBOX autocreate2 = Sent autocreate3 = Trash autocreate4 = Drafts autocreate5 = Junk autosubscribe = INBOX autosubscribe2 = Sent autosubscribe3 = Trash autosubscribe4 = Drafts autosubscribe5 = Junk quota = dict:user::proxy::quotadict quota_grace = 10%% quota_rule = *:storage=1G quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=85%% quota-warning 85 %u quota_warning2 = storage=90%% quota-warning 90 %u quota_warning3 = storage=95%% quota-warning 95 %u sieve = /%Lh/sieve/dovecot.sieve sieve_dir = /%Lh/sieve sieve_global_dir = /var/vmail/sieve sieve_global_path = /var/vmail/sieve/dovecot.sieve } protocols = pop3 imap sieve service auth { unix_listener /var/spool/postfix/dovecot-auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = vmail mode = 0666 user = vmail } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 service_count = 1 } service pop3-login { service_count = 1 } service quota-status { client_limit = 1 executable = quota-status -p postfix inet_listener { port = 12340 } } service quota-warning { executable = script /usr/local/bin/dovecot-quota-warning.sh unix_listener quota-warning { group = vmail mode = 0660 user = vmail } } ssl = required ssl_cert = </etc/pki/tls/certs/iRedMail_CA.pem ssl_key = </etc/pki/tls/private/iRedMail.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { auth_socket_path = /var/run/dovecot/auth-master lda_mailbox_autocreate = yes log_path = /var/log/sieve.log mail_plugins = quota sieve autocreate postmaster_address = root } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } For my postfix/main.cf I have this relevant setting: smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unlisted_recipient, check_policy_service inet:127.0.0.1:7777, check_policy_service inet:127.0.0.1:10031, check_policy_service inet:127.0.0.1:12340, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination

[Dovecot] dsync mirror to mailstores in director setup

27 Feb '14

Hi All, I have dsync mirror command working between a standalone dovecot server and a backend mailstore in a Dovecot Director setup. Is it safe to do the dsync directly to the backend mailstore in this setup? It doesn't seem to work via the director proxy. Thanks Murray

[Dovecot] 2 users database on same LDAP with different mail location
by Francesco 26 Feb '14

26 Feb '14

Hello, i know i know, i'm getting annoying but appearently i always come up with weird ideas and i cant seem to accomplish such a task. the scenario is that i have an LDAP server with a bunch of users. some of them are in a specific OU, and i'd like to define for all these users belonging to this OU an alternative mail location/storage. in details for all the users i'd like to use maildir storage in a directory, while for the users belonging to a specific OU i'd like to use dbox with an alternative storage attached. so i created 2 userdb like this: userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-maildir.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-dbox.conf.ext } and then defined these 2 args files: maildir: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/vmail/%$ dbox: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = OU=dboxusers,OU=lowpriority,DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/local_dbox/%$, =mail=dbox:/var/local_dbox/%$:ALT=/var/iscsi_dbox/%$ user_filter = (&(ObjectClass=person)(mail=%u)) yet it doesn't matter how hard i try if i send an email to a user belonging to the dboxusers OU i still have the user to be addressed to the maildir storage in /var/vmail am i missing something? Thanks Francesco

[Dovecot] Dovecot upgrade 1 to 2 on Debian Squeeze : broken /var/run/dovecot

Hi, I just upgraded from version 1 to version on Debian Squeeze using their backports. Like I expected my dovecot1 config had to be converted using doveconf and this I did. However, I see problems with files inside directory: drwxr-xr-x 4 dovenull root 4096 Feb 25 20:35 /var/run/dovecot All of them were created owned by root:root rw. I tried to changed, for example : chown postfix:dovecot /var/run/dovecot/auth-master but noticed when I restarted dovecot it reset the permissions back to root:root rw.

[Dovecot] Upgrading from 1.2.x -> 2.2.x in one step possible
by Götz Reinicke - IT Koordinator 26 Feb '14

26 Feb '14

Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it possible to do such a big step form 1.2 to 2.2? Thanks for comments and suggestions .

[Dovecot] Removing Mount Points
by Jeff Geiger 26 Feb '14

26 Feb '14

Dovecot version 2.1.7 If a dovecot mount point (drive) dies, and the data is restored into the same path that's no longer a mount point (subfolder), dovecot complains about a missing mount point. Is it safe to do a `doveadm mount remove {path}` to fix the error since it's no longer a legit mount point? Example: We were storing indexes on an SSD drive mounted at /mnt/ssd. That drive died. I was able to put everything back into the /mnt/ssd folder (no longer mounted, just a folder). Everything seems to be working as expected. But, when I just went to dsync an account from another server to this one, I got the following error: dsync(sales(a)foo.com): Error: Couldn't create index dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Can't create mailbox root dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Mountpoint /mnt/ssd isn't mounted. Mount it or remove it with doveadm mount remove Would doing a `doveadm mount remove /mnt/ssd` fix my issue, or cause some type of catastrophe? Thanks, Jeff Geiger jeff.geiger(a)firespring.com

Re: [Dovecot] AUTH_USER variable has invalid value in checkpassword Script

26 Feb '14

answering my own questions: > This has somehow changed and now AUTH_USER always > contains the username. This has fatal consequences as no > every owner of a valid certificate can logon as any user. I now use auth_ssl_username_from_cert = yes and this temporarily fixes my problem. Now if user A authenticates with his certificate and claims to be user B he will be logged on as user A. With ssl_username_from_cert = no (default) he was logged in as User B. > I'm absolutely sure that the value of the x500UniqueIdentifier > was stored into the AUTH_USER when I tested my setup > last year. If one looks at the source code, in particular routine env_put_auth_vars() in src/auth/db-checkpassword.c and routine auth_request_get_var_expand_table() in src/auth/auth-request.c it is clear, that this has never worked. The environemnt variable AUTH_USER always contais the username (in all Dovecot versions). It dows NOT contain the Dovecot auth_user-variable. Comparing AUTH_USER with the username makes no sense in a checkpassword-script So here's my next question: How do I find out the original username from within a chackpassword script after it has been replaced by the x500UniqueIdentifier value from a client certificate? Why is request->requested_login_user == NULL in env_put_auth_vars(). request->user contains the x500UniqueIdentifier value from the clients certificate so the original username was replaced and therefore should have been moved into request->requested_login_user. Kind regards Peter Koch

Hi, we still run dovecot 1.2.17 and upgrading is not planed for some time. But I'm asked to install a sieve system to be used with SOGo soon. What do I have to install / configure? Is installing/configuring the dovecot-sieve-0.1.19 and dovecot-managesieve-0.11.13 enough? We still use mostly the default settings for imaps/pop3s. And of course configure SOGo.

[Dovecot] AUTH_USER variable has invalid value in checkpassword Script
by dovecot.pkoch＠dfgh.net 25 Feb '14

25 Feb '14

Dear dovecot experts: We are using client certificates to authenthicate against a Dovecot server. Our certificates contain a x500UniqueIdentifier. I'm absolutely sure that the value of the x500UniqueIdentifier was stored into the AUTH_USER when I tested my setup last year. This has somehow changed and now AUTH_USER always contains the username. This has fatal consequences as now every owner of a valid certificate can logon as any user. Here are some more details of our setup: We are using a checkpassword-Script that does the following: 1. Read Username and Password from file descriptor 3 2. If (AUTH_CERT=="valid") and (AUTH_USER==Username) then user is authenticated 3 If (AUTH_CERT=="valid") and (AUTH_USER<>Username) then authentication is rejected (User a tries to logon as User B) 4 If (AUTH_CERT<>"valid) we calculate the current OATH value for Usernames TOTP-token and compare that with the provided password. The last step is the reason why we are using a checkpassword script. Our smartphone users cannot use a smartcard but enter a password that was created by an OTP generator, so programming my own checkpassword script was my only option. AUTH_USER contains the username even if the x500UniqueIdentifier from the users certificate does not, so step 2 happens when step 3 should happen. I did the initial testing with Dovecot 2.2.6. At that time we were using both port 143 and 993. We now use Dovecot 2.2.7 and port 993 only. This should not make a difference but I will recompile 2.2.6 right after sending this posting. Kind regards and thank you very much for this wonderful IMAP server Peter Koch current dovecot.conf: --------------------------------------------------------- # 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/imap.crt ssl_key = </etc/ssl/private/imap.key ssl_ca = </etc/ssl/certs/imap-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier 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 }

[Dovecot] A question regarding doveadm replicator status
by XarHs 25 Feb '14

25 Feb '14

Hello, I am using Dovecot version 2.2.10. I am quite familiar with ssh replication and I managed to set it up correctly. The only problem I see is that when i run the command: doveadm replicator status I get a wrong "Total number of known users" which is a) is different between the two (2) replicated dovecot servers, i.e. in mail1 I get a total of 21 users and in mail2 I get a total of 20 users (it should be the same, correct?) b) is not matching the total number of users I have in each server (mail1, mail2) which I am also getting when counting the total users with "doveadm" service enabled. (the command doveadm user '*' | wc lists a total of 16 users for both mail1, mail2 servers, which is also the total number of users that exist indeed in the LDAP structure with the doveadm service enabled. Is there any way to reset the value of "Total number of known users"? Do I have to delete a file in /var/run/dovecot or something in order to do it? The only way I tried (not successfully though) to reset it is by executing the command: for i in `doveadm user '*'` ;do doveadm replicator remove $i ; done which does empties all existing users (16), but leaves me with Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 5 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 4 in mail2 server, i.e. the value is 5 (21-16) for mail1 and 4 (20-16) for mail2 server. After seeing that I tried to restart dovecot service, which again ended in the following numbers: Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 21 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 20 in mail2 server thus their values augmented back to +16, meaning dovecot read succesfully my 16 users. I have not found a way to successfully reset the "Total number of known users" numbers back to the valid 16 users, which is also returned by running the command: doveadm user '*' | wc Why do I have those differences? How is the "Total number of known users" being calculated? What should I do to effectively reset to to the normal value (which in my case is 16)? Thanks in advance.

[Dovecot] tests with metadata module
by Mihai Badici 25 Feb '14

25 Feb '14

--Repost after subscription as list member --- I made some tests with metadata support in dovecot 2.2.10. Previously I had dovecot 2.2.4 with external metadata plugin who work well. I use dovecot with roundcube and roundcube plugins from kolab project . First, the feature activation was tricky and rather undocumented. I spent about half hour googling, after that I set: imap_metadata = yes and mail_attribute_dict = file:%h/shared_metadata I think you cold put those lines in the 20-imap.conf example file commented; that way will be easy for us to activate. Because I changed the location of shared_metadata, all folders was unannotated . I went in folder manager in roundcube and set folder "calendar" as calendar type and so on.

[Dovecot] Detail improvement: %c variable
by Hadmut Danisch 25 Feb '14

25 Feb '14

Hi, although dovecot is great and almost exactly solving my problems and fitting my requirements, there is an odd detail that causes me problems: The %c variable. (See http://wiki2.dovecot.org/Variables ) I'm managing an IMAP server for an association, which is connected to an LDAP server. Users can connect in three ways: IMAPS from the internet, IMAP from local acccounts, and IMAP through a Web->IMAP interface, which is protected through additional one-time-passwords. The web gateway is intended to be used from untrusted computers as well, so the IMAP password entered through the Web site must not be the same as the password used on IMAPS. I have solved this problem by using %s%c as part of the LDAP user_filter. When people connect over IMAPS, this becomes imapsecured (%s=imap, %c=secured), while an unencrypted connect becomes imap (%s=imap, %c=) Unfortunately, this works only, if the web interface and the IMAP server are located on different (virtual) machines. But if the web gateway and dovecot are no the /same/ machine, this does not work anymore, since %c becomes "secured" on localhost, even if unencrypted. It causes a lot of trouble and headache. Please add a configuration variable to configure, whether %c should become "secured" for unencrypted traffic on the loopback device (localhost). regards Hadmut

[Dovecot] realtime backup with LDA?
by Francesco 25 Feb '14

25 Feb '14

Hello everyone, i was reading the dovecot-lda documentation as i'm using LDA as a delivery agent on my current mailserver configuration. I was curious to know if there are some options for having a message to be delivered to a "twin mailbox" upon delivery. this twin mailbox would work as a backup archive for recovering emails in case the user accidentally deletes them. so if i have a user which is alice i would create a second mailbox named backup_alice or whatever respecting a predictable schema and then every mail delivered to alice would also be delivered to backup_alice. do you know if this can be done? have any example? i was also planning to use shared folders + ACLS to have backup_alice accessible as a read only mailbox directly from the alice imap account. thanks in advance Francesco

[Dovecot] Why are ACLs for non-existent mailboxes accepted?
by Boris 25 Feb '14

25 Feb '14

Dovecot 2.2.9-1 accepts SETACL commands that share mailboxes to non-existent mailboxes. There is no error message. Is this intended behavior? I think it's bad because clients present a success message when indeed the intent of the user failed. Typos are hard to catch.

[Dovecot] dsync, a zero-way synchronisation tool?
by Fabiano Sidler 24 Feb '14

24 Feb '14

Hi folks! I have set up dsync replication with SSH according to http://wiki2.dovecot.org/Replication with the exception of having system users and calling doveadm dsync-server directly from authorized_keys, because the wrapper script posted on the above site is needless (at least in 2.2.10). However, while the two instances connect well to each other, no synchronisation is performed at all, the mailboxes happily remain untouched. I've then temporarily replaced SSH with socat and captured the traffic. Any hints what goes wrong? Unfortunately there are no logs to provide... Greetings, Fabiano

[Dovecot] doveadm mailbox command in multi instance setup
by Peer Heinlein 22 Feb '14

22 Feb '14

We're running Dovecot in a multipe instance cluster with individual userdb-querys to different LDAP-Servers. As far as I can see there's no way to use the doveadm mailbox command with different Auth-Sockets or different configurations. While root@dobby4:/etc/dovecot# doveadm user -a /var/run/dovecot-xy/auth-master p.heinlein(a)example.com field value uid 10000 gid 10000 home /mail/example.com/123456/ mail mdbox:~/mdbox quota_rule2 *:storage=50G is working, using doveadm -c /etc/dovecot/dovecot-xy.conf mailbox list -u p.heinlein(a)example.com does NOT an (user unknown). How can use a different auth socket with "doveadm mailbox" commands? (Maybe using the network socket could be a working way, but what about normal way on the command line?)

Dovecot Version: 2.2.12 Postfix Version: 2.9.6 Hello I've configured the quota-status service (socket and port).

How it's possible to debug the quota-status for understand why to postfix the service return DUNNO and not 552 ?

It seems that dovecot is using the current time, not a maildir file's mtime for INTERNALDATE when a message is re-indexed: $ cd Index $ rm -rf .INBOX $ cd ../Maildir/cur $ stat * File: `1392914632.P54451Q0M08633.smtpin01,S=2215,W=2249:2,' Size: 960 Blocks: 8 IO Block: 1048576 regular file Device: 36h/54d Inode: 11132959 Links: 1 Access: (0600/-rw-------) Uid: ( 8/ mail) Gid: ( 8/ mail) Access: 2012-01-01 00:00:00.000000000 +0000 Modify: 2012-01-01 00:00:00.000000000 +0000 Change: 2014-02-20 16:46:20.000000000 +0000 Birth: - $ telnet imap01 143 Trying 10.5.45.1...

[Dovecot] Syntax of pattern in map section
by da-dovecotlist-15＠abelonline.de 20 Feb '14

20 Feb '14

I can't seem to find any documentation on the meaning/syntax of the "pattern" variable in map sections that are found in dovecot-dict-sql.conf.ext for example. I am trying to setup shared folders. The only thing[1] I found is: >>First you'll need to know what kind of dict paths the code uses. ACL >>plugin uses these paths: >> >>shared/shared-boxes/anyone/$owner >>shared/shared-boxes/user/$user/$owner >>shared/shared-boxes/group/$group/$owner What is a "dict path"? Is this some kind of hard coded identifier in the Dovecot code? I need to understand how they work because I can't use the example in http://wiki2.dovecot.org/SharedMailboxes/Shared. This is because in my PostreSQL table users are not a single column but two columns with the local and domain part[2]: Table "public.shared_mailboxes" Column | Type -----------------------+------------------------ shared_mailbox_local | character varying(64) shared_mailbox_domain | character varying(253) shared_to_local | character varying(64) shared_to_domain | character varying(253) How should a map section look in this case? [1]http://www.dovecot.org/list/dovecot/2009-April/038922.html [2]I did this in order to use REFERENCES to ensure the user exist. Kind regards

[Dovecot] Warning: mysql: Query failed, retrying: Unknown column 'filter' in 'where clause'

Hi List, I have a problem with dovecot 2.2.12 and sieve-filter call: su -c 'sieve-filter -D -v -W -C -u account(a)domain.tld /var/vmail/domain.tld/account/.sieve INBOX.Refilter' vmail gives me sieve-filter(vmail): Error: user account(a)domain.tld: Auth USER lookup failed sieve-filter(vmail): Fatal: Internal error occurred. Refer to server log for more information. on log file I see this: Feb 17 16:21:34 mail1 dovecot: auth-worker(8430): Warning: mysql: Query failed, retrying: Unknown column 'filter' in 'where clause' Feb 17 16:21:34 mail1 dovecot: auth-worker(8430): Error: sql(account(a)domain.tld): User query failed: Unknown column 'filter' in 'where clause' but I never used filter in dovecot: grep -iR filter /etc/dovecot/ gives me no result (and yes the dir is right). Any Idea whats wrong? I know it tells me, that the column is missing in the Database - but why I need it? I also never see it documented somewhere: http://wiki2.dovecot.org/AuthDatabase/SQL http://wiki2.dovecot.org/PasswordDatabase/ExtraFields Thomas

[Dovecot] virtualfolders all mails minus duplicates
by Francesco 19 Feb '14

19 Feb '14

Hello everyone, i'm trying to mess up a bit with virtual folders and i'm trying to perform something like this: i'd like to create an IMAP virtual folder which shows me all the emails in in INBOX and subfolders but by removing "duplicates" what i mean as duplicates? simply i can recognize duplicate emails as the ones with the same message-id in the header (this was just an idea). in that way if i have a message which is present in more then one folder then it's displayed only once. i considered the idea of using message-id in the header as a criteria, but i don't know if this can be done in this way or in any way at all. any suggestion is really welcome. i'm using dovecot 1.2.15. this is a namespace example just for reference: for INBOX: namespace private { separator = . prefix = INBOX. #subscriptions = yes #list = no inbox = yes } for virtuals: namespace private { prefix = v. separator = . location = virtual:/var/utenti/%Ld/%n/VirtualFolders list = yes inbox = no subscriptions = yes hidden = no } as of now i'm running a virtualfolder which shows messages flagged as important which is done like this: INBOX INBOX.* all flagged hope you can provide me with some hints. Thanks very much Francesco

Hi, i want use dovecot and plugin quota to inform users about exceeded space. I also configure postfix to rewrite envelope_sender so envelope_sender<>header: from. Dovecot sent mail with information about exceeded space to email in envelope_sender. It is possible to configure that dovecot sent mail to header from address? I need use sender_canonical_maps in postfix because i want also relay mail outgoing.

[Dovecot] Filtering spam in an offlineimap + dovecot setup
by Alan Schmitt 19 Feb '14

19 Feb '14

Hello, To easily access my mail both offline on my computer and on my phone, I am synchronizing a local copy on my computer using offlineimap. As the spam filtering options provided on the server are not sufficient, I am now looking into client-side spam filtering. My current setup is as follows. Mail is synchronized using offlineimap, and delivered to a local dovecot server: --8<---------------cut here---------------start------------->8--- [Repository LocalIMAP] type = IMAP preauthtunnel = /usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap -c ~/.dovecotzimbra.rc --8<---------------cut here---------------end--------------->8--- The configuration of the local server is simply: --8<---------------cut here---------------start------------->8--- protocols = imap mail_location = maildir:~/.Maildir/zimbra:INBOX=~/.Maildir/zimbra/.INBOX --8<---------------cut here---------------end--------------->8--- I then read my mail using gnus, and index it using notmuch. A suggestion I've been considering is use the pigeonhole sieve extprograms plugin (http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms) to call the spam filter (I've been looking at dspam at the moment). However, I could not find how to configure the use of sieves in the context of offlineimap. Hence my questions: Is it possible to use dovecot sieves in such a setting? Is there a howto that explains how to do it? Should I try to do things in a different way? (I'm ready to change my setup, as long as I can keep an offline copy of my email in sync with a server copy.) Thanks a lot for any suggestion, Alan PS: I used to use SpamSieve (http://c-command.com/spamsieve/) on a Mac Mini that was running continuously as a spam filter drone. This machine has been retired and I'm basically looking for leaner ways to do a similar thing.

[Dovecot] dovecot antispam plugin not found
by Alan Schmitt 19 Feb '14

19 Feb '14

Hello, I'm trying to setup dovecot-antispam, and even though the configuration and the installation seem to have gone well, dovecot is telling me it's not finding it. Here is the symptom: schmitta@top-wifi ~> /usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap -c ~/.dovecotzimbra.rc Fatal: Plugin 'antispam' not found from directory /usr/local/Cellar/dovecot/2.2.10/lib/dovecot However there seems to be a plugin there: schmitta@top-wifi ~> ls -al /usr/local/Cellar/dovecot/2.2.10/lib/dovecot/ | grep antispam -rwxr-xr-x 1 schmitta admin 38460 18 fév 22:40 lib90_antispam_plugin.bundle I note that it is the only plugin with the ".bundle" extension, if it's important.

[Dovecot] Virtual folder for selected users only? (1.2.15)
by Sebastian Schäfer 19 Feb '14

19 Feb '14

hi, i want to set up virtual folders just for some users on our mailserver. the server is set up with a virtual system-user for each of our clients having multiple mailboxes/users (provided by dovecot-mysql). mailboxes are located: /var/mails/SYSUSER/MAILBOX f.e. my mailbox-folder is set to /var/mails/bergschaf/sebastian[at]bergschaf.net {homedir} = /var/mails {maildir} = bergschaf/sebastian[at]bergschaf.net user_query = SELECT homedir AS home, concat('maildir:', maildir) AS mail, uid, gid, concat('maildir:storage=', (quota*1024)) as quota FROM mail_users WHERE username = '%u' now i want to add virtual folders to my mailbox without affecting any other client/mailbox on the server. i already tried to add a namespace "virtual" like mentioned in the wiki and in some other hotwo-guides, but this points to the need to create a "virtual"-folder for each mailbox what i would like to avoid. (f.e. location = %h/%u/virtual => /var/mails/sebastian[at]bergschaf.net). is it possible to enable a namespace just for some selected users on the server? if that's not possible - i'm not sure how to set the location-directive correctly, because i can't find a variable pointing to the maildir: %u => sebastian[at]bergschaf.net %h => /var/mails ...but how should i point the location to {homedir}/{maildir}/virtual? thanks! sebastian dovecot --version 1.2.15

[Dovecot] failed: Message has been copied too many times
by Angel L. Mateo 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.1.16 in a ubuntu 12.04 server, with lazy_expunge, SiS and mdbox format. The problem I'm having is that the index for one the mailboxes of one of my users is growing too much. This is not the first time of this problem. In previous cases, is because a message is duplicated thousand of times (I haven't found any reason for this). In these cases, moving messages to other folder and moving again to this same folder fixes the problem. So I have tried this, and I have moved all messages from this folder to another one. But this time, after this, indexes directory is still using a lot of space. And the folder seems to have more serious problems: amateo_adm@myotis51:~$ sudo doveadm search -u vlo mailbox BORRADOS.INBOX.MNCS doveadm(vlo): Error: Syncing mailbox BORRADOS.INBOX.MNCS failed: Message has been copied too many times (59306 + -1) I have tried to delete the folder, with the same result: amateo_adm@myotis51:~$ sudo doveadm mailbox delete -u vlo BORRADOS.INBOX.MNCS doveadm(vlo): Error: Can't delete mailbox BORRADOS.INBOX.MNCS: Message has been copied too many times (59306 + -1) And to purge user's mailbox, but it didn't fix the problem. PS: If this could help, BORRADOS. is the namespace used by lazy_expunge plugin. -- Angel L.

Re: [Dovecot] Virtual folder for selected users only? (1.2.15)
by Sebastian Schäfer 19 Feb '14

19 Feb '14

> thats very outdated, you should upgrade 2.1.x / 2.2.x latest I would like to avoid this, because the 1.2.15 is running extremely stable for a long time. (also it's the most recent version on this old squeeze-machine if not using backports) As far as I see, the virtual folders are fully supported since 1.2.x - am I wrong? What are the advantages of upgrading to 2.x? Are there security issues? Thanks! best, sebastian

[Dovecot] Dovecot, mysql, and quota
by David Mehler 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.2 and wanting to get quotas going. I've got the plugins loaded appropriately and am wanting to configure a dictionary backend to talk to my mysql database. I've got a single database called mail which has all the mail-related items in it. One table is for virtual users which postfix uses. It looks like this: CREATE TABLE `virtual_users` ( `id` int(11) NOT NULL auto_increment, `domain_id` int(11) NOT NULL, `password` varchar(128) NOT NULL, `email` varchar(100) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8; and a user looks like: INSERT INTO `mail`.`virtual_users` ( `id` , `domain_id` , `password` , `email` ) VALUES ( '1', '1', SHA2( 'PasswordGoesHere', 512) , 'username(a)domain.com' ); plugin { # SQL backend: quota = dict:User quota::proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Now when creating the quota table i'd like to have the username field linked to my virtual_users table username field, so I don't have to set up two tables both with the same username information in it. Can someone check me on this design so that if I delete a virtual user out of the virtual_users table the coresponding row in the quota table is also eliminated? My second question has to do with global and per user quotas. If I have something like this: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 262144, messages integer not null default 0, primary key (username) ); 256MB for all users by default, but then if I give a user a 100MB value in the bytes field of their quota entry would that be a per-user quota? Thanks. Dave.

[Dovecot] Index corruption with 2.2.12 when moving a message
by Bojan Smojver 19 Feb '14

19 Feb '14

Just bumped into this today, when I upgraded to a testing package in Fedora: https://admin.fedoraproject.org/updates/FEDORA-2014-2672/dovecot-2.2.12-1.f… For details, see this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1066709 Haven't seen this kind of thing before. Sure, it worked the second time I tried to move the message to another folder (I'm guessing index got rebuilt or something), but still, looks suspicious. Anyway, I'm using mbox format mailboxes, if it matters. Client was Gnome Evolution 3.10.4. -- Bojan

[Dovecot] Problems with dovecot 2.1.7, spamassassin 3.3.2 and antispam plugin
by Dean Carpenter 18 Feb '14

18 Feb '14

This might be a fairly long message, but I wanted to be sure to include as much information as possible. I'm having an issue with the dovecot-antispam plugin in that it seems to be unable to successfully run anything from the pipe backend. To qualify that, they run, but they fail ... Running /usr/bin/sa-learn directly always returns with an error code of 1, and the bayes DB isn't actually updated. Running the /usr/local/bin/sa-learn-pipe.sh script from the example will run sa-learn successfully, but sa-learn fails partway through, right on a sql DB access. I have both bayes and FuzzyOcr data stored in mysql, and the error occurs on accessing either one. That is, I've tested with FuzzyOcr enabled, and it fails on the db access to the FuzzyOcr DB, and I've tried it with FuzzyOcr disabled. In that case, it fails on the access to the bayes DB. The error line right there is : libgcc_s.so.1 must be installed for pthread_cancel to work Since sa-learn terminated prematurely, the bayes DB isn't updated at all. Running /usr/bin/sa-learn or the script /usr/local/bin/sa-learn-pipe.sh directly from cmdline works fine though - sa-learn completes correctly and updates the bayes DB properly, I can see the new tokens. $ sa-learn-pipe.sh --spam < /usr/share/doc/spamassassin/examples/sample-spam.txt $ sa-learn --spam /usr/share/doc/spamassassin/examples/sample-spam.txt I think it would be great to have a dedicated logfile for antispam, one that would capture both stdout as well as stderr. These tests are being done on a clean Ubuntu 13.04 system. I'm rebuilding the VM repeatedly as I configure the various pieces, and can test any changes or whatever you might suggest very easily. I've fully scripted the install and configuration of Exim4, Dovecot, Spamassassin, Clamav, Percona/Mysql, Roundcube, and can build a full VM under Virtualbox or any VPS in less than 10 minutes. Ubuntu 13.04 Dovecot 2.1.7 dovecot-antispam 2.0+20120225-3 Anyone else using the antispam plugin with spamassassin 3.3.2 ?

[Dovecot] SMTP configuration for director mail cluster
by Murray Trainer 18 Feb '14

18 Feb '14

HI All, I have setup my Dovecot director proxies and Dovecot backend mail stores. I intend setting up several incoming and outgoing Exim MTA's. I am a bit confused about what I need to run on the backend Dovecot MTA's to get the incoming mail delivered to them. Do I need to install Exim on them or use LMTP to receive mail from the MTA's? Also, can I directly deliver mail to the mailstores or do I have to go through the director proxies using lmtp? Note that I am using Director with the mailboxes on NFS backed storage. Thanks Murray

[Dovecot] PARTIAL results and UIDs
by Anders Thøgersen 18 Feb '14

18 Feb '14

Hi, I have had a look at dovecot 2.2.12 and think that I may have run into an issue with PARTIAL results. I have a mailbox with 9 emails having UIDs from 1 - 9. One of these emails contains the STRING "RFC" in the Subject header. The following SORT command with this mailbox selected does not return any emails: A4 UID SORT RETURN (COUNT PARTIAL 1:3) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:3 NIL) COUNT 1 A4 OK Sort completed (0.000 secs). Here COUNT is 1, but the result is NIL. Changing the partial range to 1:5 returns the expected result: A4 UID SORT RETURN (COUNT PARTIAL 1:5) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:5 5) COUNT 1 A4 OK Sort completed (0.000 secs). It may be that UIDs are used instead of sequence numbers. Regards Anders

[Dovecot] Possible error in function mailbox_autocreate
by Potapov Sergey 18 Feb '14

18 Feb '14

Hi! in mailbox_autocreate: if (mailbox_create(box, NULL, FALSE) < 0) { errstr = mailbox_get_last_error(box, &error); if (error != MAIL_ERROR_NOTFOUND) { <<< May be MAIL_ERROR_EXISTS should be here? mail_storage_set_critical(box->storage, "Failed to autocreate mailbox %s: %s", box->vname, errstr); return -1; } Some time I got this error when two connections tries to create INBOX at same time. ______ С уважением, Сергей Потапов

[Dovecot] The submission server
by Peter Mogensen 18 Feb '14

18 Feb '14

Hi, As many others I'm looking forward to the submission server. But I have a question: A use-case with authenticated SMTP is to have the server restrict From/Sender headers based on the authenticated user. (and adding the actual authenticated user to the headers) Postfix supports this (AFAICS) and I can't imagine Exims doesn't either with it's elaborate config possibilities. But will that be possible with the Dovecot submission server? /Peter

[Dovecot] Master user ldap config
by Roman Gelfand 17 Feb '14

17 Feb '14

I am using outlook 2010 to login to pop3 mailbox as master user. The user name I provide is john@domain.tld*test@domain.tld. The password is that of test(a)domain.tld. I am not quite sure as to how to specify ACL. I guessed the ACL specs as per ldap config, below. But it is not working. The master password is stored in master-users file. The ldap config is # debug_level = 9 hosts = 192.168.0.22:389 ldap_version = 3 auth_bind = yes dn = dlookup(a)domain.local dnpass = password base = OU=Test Users,DC=domain,DC=local scope = subtree deref = never user_filter = (&(Mail=%u)(objectClass=person)(!(userAccountControl=514))) pass_filter = (&(Mail=%u)(objectClass=person)(!(userAccountControl=514))) pass_attrs = uid=user, userPassword=password, =proxy=y, =destuser=%u*masteruser, =pass=mastpass default_pass_scheme = CRYPT user_attrs = =uid=999,=gid=8,=home=/vmail/%Ld/%Ln/home/,=mail=maildir:/vmail/%Ld/%Ln/Maildir/ The dovecot.conf is auth_mechanisms = plain login disable_plaintext_auth = no base_dir = /var/run/dovecot/ log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info.log mail_debug = no auth_debug = no auth_verbose = no auth_debug_passwords = no first_valid_gid = 8 instance_name = test last_valid_gid = 8 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail passdb { args = /etc/dovecot/conf.d/users.conf driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap-test.conf driver = ldap } auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/master-users master = yes pass = yes } service auth { inet_listener { port = 10305 } unix_listener auth-master { group = mail mode = 0600 user = mail } } userdb { args = /etc/dovecot/conf.d/users.conf driver = passwd-file } userdb { args = /etc/dovecot/master-users driver = passwd-file } userdb { args = /etc/dovecot/dovecot-ldap-test.conf driver = ldap } protocol lmtp { postmaster_address = postmaster(a)domain.tld mail_plugins = sieve } protocol lda { postmaster_address = postmaster(a)domain.tld hostname = server.domain.tld # Sieve plugin for local delivery agent mail_plugins = cmusieve log_path = /var/log/dovecot-local-deliver.log }

[Dovecot] FTS question
by Peter Chiochetti 14 Feb '14

14 Feb '14

Please advise: Can I override the user parameter in solr indexing and searching? To understand, why I wish for that, please consider my setup: # Mail is fetched from a remote imap server # dovecot LDA stores into Maildir as system user # Several virtual users exist in a static userdb # They all share the system users Maildir # everybody can see, move, delete etc. all the mails # dovecot mail_log plugin is used for audit So it is like all/only shared folders, isn't it? A cheap groupware, maybe… This works exceptionally well (2.0 and 2.2.11 as of now). The problem: When e-mails are indexed by solr, the uid of the virtual user is passed on, and only this user will later find that mail in a server side body search. I tried and made "user" an ignored field in solr schema, but then nothing will ever be found, because it is dropped when indexing, but will be asked for in searching. So far, what I learned in a day. Maybe someone can help? Thank You in advance -- peter

Re: [Dovecot] Maildir format
by Roman Gelfand 14 Feb '14

I am not sure where I went wrong here. The wiki says... By default Dovecot uses Maildir++ directory layout for organizing mailbox directories. This means that all the folders are directly inside ~/Maildir directory: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX. The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. ~/Maildir/.folder/ is a mailbox folder ~/Maildir/.folder.subfolder/ is a subfolder of a folder (ie. "folder/subfolder") You can also optionally use the "fs" layout by appending :LAYOUT=fs to mail_location. This makes the folder structure look like: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX, just like with Maildir++. ~/Maildir/folder/ is a mailbox folder ~/Maildir/folder/subfolder/ is a subfolder of a folder Here is my folders. Though there are emails in the inbox, I am not seeing anything in new/ or cur/ folders. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.doe/Maildir/ drwx------ 5 999 mail 4096 Feb 14 10:06 . drwx------ 3 999 mail 4096 Feb 12 19:53 .. drwx------ 2 999 mail 4096 Feb 14 10:02 cur -rw------- 1 999 mail 17408 Feb 14 10:02 dovecot.index.cache -rw------- 1 999 mail 2896 Feb 14 10:06 dovecot.index.log -rw------- 1 999 mail 51 Feb 14 10:06 dovecot-uidlist -rw------- 1 999 mail 8 Feb 12 19:53 dovecot-uidvalidity -r--r--r-- 1 999 mail 0 Feb 12 19:53 dovecot-uidvalidity.52fc176c drwx------ 2 999 mail 4096 Feb 14 10:02 new drwx------ 2 999 mail 4096 Feb 14 09:59 tmp root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/new total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 .. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/cur total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 ..

I see where the mail box meta data is kept. But don't the actual emails. I was under the impression the impression the email was kept, on the server, as .eml. Thanks in advance

[Dovecot] Hybrid of linux user accounts and virtual user accounts configuration
by Derek Winterstien 14 Feb '14

14 Feb '14

So some system users have their email forward to Maildir in their /home/user directory (virtual_alias_maps) for their domain . This I have working! And the rest are non-system users, ie virtual users listed in a plain text file and their MailDir will be in /home/vmial/domain.com/user/ The virtual user part is working 100% with postfix and dovecot accepting mail for each virtual alias and system account holders popping in to retrieve their mail. The second part is working 50%. I have email for virtual users going into /home/vmail/domain.com where they are supposed to go. Now, I am very confused on how to configure dovecot to allow folks without system accounts to login and retrieve their email. I have been going through one guide after another. When I start changing things I break the first working part, the system accounts being able to get their mail. Changes to dovecot.conf to get the second working negatively impact the first. Also, a lot of documentation is out of date, which further complicates matters. Postfix/Dovecot: Postfix version: 2.6.6 Dovecot version: 2.0.9

[Dovecot] Feature request about Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths)
by Steffen Kaiser 14 Feb '14

14 Feb '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since some time I'm plagued by internal login failures. With v2.2.10 I got the some additional error, that I should raise the process_limit for the imap service, then I got the hint to raise vsz_limit for the lmtp and imap serverices. These hints are very helpful and are some sort of unique feature of Dovecot - descriptive error messages. Now I have upgraded a Webfrontend behind imapproxy -> Dovecot and get this during a phase in the day, several of messages go to large internal mailing lists and lots of users are connecting/disconnecting via IMAP, POP,& Web: <login success> imap: Error: Disconnected from auth server, aborting (client-pid=2296 client-id=17278) imap-login: Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths) .... . doveadm and to query the userdb [I have some processes that use Dovecot UserDB to query user data, which do not cache its information], & login into IMAP fail as well. Even connecting to the auth-userdb socket reveals no reaction - usually the VERSION prompts immediately. I now suppose that the deault auth_worker_max_count=30 is the culprit, because I query LDAP for passdb and userdb and client_count, but client_limit=0. Would it be possible to add a warning to all limits "that max out"? Or, if such "generic error" occurs, could Dovecot be enabled to dump a list of which limit is used up to which level? Or something like that. Also, I'm surprised to find that the "Internal login failure" is at "Info" level only. Also note: It is very possible that the problem is caused by a client that goes havoc. ====== Just to no trigger the "post your config" reply I give now and then myself: # 2.2.10 (5432b55a2b87): /usr/local/dovecot-2.2.10/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.8 auth_cache_size = 10 M auth_debug = yes auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot2.2/ default_vsz_limit = 512 M deliver_log_format = msgid=%m: %$ %p/%w "%f" "%s" dict { acl = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext quota = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext } instance_name = dovecot2.2 lda_mailbox_autocreate = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot/dovecot2.2.log log_timestamp = "%F %H:%M:%S " mail_debug = yes mail_gid = vmail mail_log_prefix = "%Us(%u) [%p]: " mail_max_userip_connections = 0 mail_plugins = " quota notify mail_log zlib acl" mail_shared_explicit_inbox = yes mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = users.%%u. separator = . type = shared } 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 = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = proxy::acl antispam_allow_append_to_spam = yes antispam_backend = spool2dir antispam_spam = SPAM+ReportAsSPAM antispam_spool2dir_notspam = /tmp/spamspool/%%020lu-%%05lu-%u-H antispam_spool2dir_spam = /tmp/spamspool/%%020lu-%%05lu-%u-S antispam_trash = trash;TRASH;Trash;spam;SPAM;Spam;junk;JUNK;Junk;Deleted Items;Deleted Messages;Gel&APY-schte Elemente;Gel&APY-schte Objekte;Junk E-mail;Junk-E-Mail;INBOX.Trash;INBOX.TRASH;INBOX.trash mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size vsize from subject quota = dict:User quota::proxy::quota quota_rule = *:storage=300MB quota_rule2 = Trash:storage=+30M recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags sieve_max_actions = 0 sieve_quota_max_storage = 3M } protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener auth-client { mode = 0766 } unix_listener auth-userdb { mode = 0766 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service doveadm { unix_listener doveadm-server { mode = 0666 } } service imap-login { process_min_avail = 4 service_count = 0 vsz_limit = 768 M } service imap { process_limit = 10000 vsz_limit = 768 M } service lmtp { vsz_limit = 768 M } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { process_min_avail = 5 service_count = 0 vsz_limit = 512 M } ssl_ca = </etc/ssl/certs/ca.crt ssl_cert = </etc/ssl/certs/imap.pem ssl_key = </etc/ssl/private/imap.key userdb { driver = prefetch } userdb { args = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext default_fields = home=/home/%u uid=vmail gid=vmail driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol lda { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol imap { mail_plugins = " quota notify mail_log zlib acl imap_quota imap_zlib imap_acl antispam" } - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUvjzZnD1/YhP6VMHAQKElQgAoBU3v5JD9kFNzan06UFG88sucvf6HZru gLF6l7IZSWiY/IwouTBoseJcrXmgVG9sCk12gxvonO3iT0KVu1PyJZeTMaKtY3hS I37J4iS88pmY3cGQNguYMSidrIvNOt6SW+Jv/9QxuYTJKYCqoEZRdP8yJ+dvrmQw zpZEzKqcV+x4ofDLcpRxLZtXwb+Bl5AA9hoe/Md/UqzUEa9CYyvANoX63/zY7WS5 1VpK+a80/L6ukJUt9tPQTWSe0ALYmL6Cd4tAdC2Bsq7rN+6SQIcjxxr/9v8Byj8Q BdtwUhpTazVm7CLOjnFiWxfXmHCL9BNrQUBBAd5docSydNDEUMmQng== =r9QR -----END PGP SIGNATURE-----

[Dovecot] Status
by Timo Sirainen 14 Feb '14

14 Feb '14

So, just some quick notes: - dovecot.org server was down a couple of days again, need to find time to move it to a VM.. - my tss(a)iki.fi emails were also broken for some hours at least and it was bouncing back all mails to it during the time - I fixed some bugs reported by people, but I did it in airplane so couldn't reply back with links to the fixes in hg repo. I'll probably do that tomorrow. But you can already check if your reported bug has been fixed in http://hg.dovecot.org/dovecot-2.2 - I'm planning on going through Dovecot list's mails this week and make v2.2.11 release - although it looks like I've a flu, so lets see how far I can get.. - hopefully by the beginning of March I'll have more time again

[Dovecot] Sieve is not getting the propper RCPT from the LMTP daemon
by klondike 14 Feb '14

14 Feb '14

Hi! Since the setup I use is a bit strange let's go for it first: * The system uses postfix as MTA and dovecot as LDA after alias translation by local via LMTP * The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1 * The SMTP server at gentoo.org is configured to send me a backup of my emails to klondike+gentoo (at) xiscosoft.es using sendmail * The email is received by the server and then (hopefully filtered). * The email comes with two Delivered-To: headers, the first one has the correct address, the second one has the gentoo address. The interesting part of the filter is this: if envelope :detail "to" "gentoo" { addflag "\\Seen"; fileinto "gentoo"; stop; } But this doesn't seem to work, I enable debugging with the following lines: require "vnd.dovecot.debug"; require "envelope"; require "variables"; if envelope :matches "to" "*" { debug_log "envelope to `${1}'"; } if envelope :matches "from" "*" { debug_log "envelope from `${1}'"; } The relevant lines for the test e-mail I sent are these: sieve: info: started log at Dec 24 13:37:23. main script: line 9: info: DEBUG: envelope to `klondike (at) gentoo.org'. main script: line 10: info: DEBUG: envelope from `klondike (at) gentoo.org'. info: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX'. The thing is that the to envelope should be instead klondike+gentoo (at) xiscosoft.es as show by the lmtp logs: Dec 24 13:37:23 localhost dovecot: lmtp(26249): Connect from local Dec 24 13:37:23 localhost dovecot: lmtp(26249, klondike): Cd6YHwOAuVKJZgAA0J78UA: sieve: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX' Dec 24 13:37:23 localhost dovecot: lmtp(26249): Disconnect from local: Successful quit Dec 24 13:37:23 localhost postfix/lmtp[26248]: 657D9101E5E: to=<klondike+gentoo (at) xiscosoft.es>, relay=xiscosoft.net[private/dovecot-lmtp], delay=0.29, delays=0.05/0.03/0.03/0.18, dsn=2.0.0, status=sent (250 2.0.0 <klondike+gentoo (at) xiscosoft.es> Cd6YHwOAuVKJZgAA0J78UA Saved) I really have no idea of why sieve is behaving like this as the evelope address is sent properly by postfix's lmtp according to the logs. Any ideas? klondike PS: please do CC me when answering this e-mail as I'm not subscribed to the list yet

[Dovecot] master user and ACL's
by Peter Mogensen 14 Feb '14

Hi, Quick question...I read in the docs that: "Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user." ... and that the standard workaround is to return master_user=%u from the userdb. But why is the master_user authn-id used in the ACLs and not the authz-id (requested-login-user) ? Isn't the whole point of SASL authz-id semantics to have authorization resolved based on the authz-id? /Peter

[Dovecot] Public folder doesn't work
by vupibi 14 Feb '14

14 Feb '14

Hey, I have some issues with dovecot, because the public folder won't show up in Mail accounts. Dovecot is installed via zentyal 3.3. I tried several settings, but I dont get it running. What I tried is adding this to my dovecot.conf file # User's private mail location mail_location = maildir:~/Maildir # When creating any namespaces, you must also have a private namespace: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/var/vmail/public subscriptions = no } But nothing happened. I tried it with # Umask for shared folders umask = 0007 with subscriptions = yes tried creating the folder first like this touch /var/vmail/public/dovecot-shared chown -R ebox /var/vmail/public find /var/vmail/public -type d -print0 | xargs -0 chmod 2770 find /var/vmail/public -type f -print0 | xargs -0 chmod 660 But i had no success. Any Ideas how to get it running?

[Dovecot] Exclude Users from replication/sync
by Daniel Stoye 14 Feb '14

14 Feb '14

Hi All, i'm searching for a way to exclude certain users from dovecots replication mechanism. I can't use the first_valid_uid setting, because the uid of my pam (ldap) users und my system users are mixed up. So, is there a way to limit my users i currently have in my userdb or somehow exclude specific uids from replication? Thanks, Daniel

[Dovecot] v2.2.12 released
by Timo Sirainen 14 Feb '14

14 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz.sig POP3 server code changes rarely, so I haven't spent time adding automated testing for it. So of course now that it changed in v2.1.11 there was a bug that caused it to crash most of the time (except for the test case I was using while developing it). This release fixes it, no other changes.

[Dovecot] Dovecot 2.2.10 crash / infinite loop bug
by Jani Hast 14 Feb '14

14 Feb '14

Hello, I though this bug should be reported, although there is workaround already made and in use. Dovecot 2.2.10 crashes into out of memory error when there is defined system users (userdb+passdb) and own virtual users (userdb+passdb). Removing either one solves the issue and Dovecot is working as it should. When memory leak (I replaced pw_init and gr_init with the version that is found from 2.1.17) is fixed from lib/ipwd.c source, the auth worker gets to infinite loop and authentication timeouts(timeout was increased, but worker does not end what ever it's doing). This far I got chance to debug this before other passdb was removed due lack of time. Here's logs, configs and backtrace: Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: pool_system_realloc(268435456): Out of memory Feb 1 07:39:19 openbsd dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: master: service(auth-worker): child 30906 returned error 83 (Out of memory (service auth-worker { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) Feb 1 07:39:19 openbsd dovecot: auth: Error: static(email@localhost): passdb doesn't support lookups, can't verify user's existence Feb 1 07:39:19 openbsd dovecot: lda: Error: user email@localhost: Auth USER lookup failed Feb 1 07:39:19 openbsd dovecot: lda: Fatal: Internal error occurred.

[Dovecot] sqlite queries for master user
by Alan Chandler 14 Feb '14

14 Feb '14

Hi I am trying to achieve the following functionality "usera" can't login because his account is set non active. there is a deny query that checks this. a master user ("masteruser") should be able login using "usera*masteruser" syntax to this disabled account I just tried it with auth_debug set on, but the deny query is being run for usera, presumably because my master definition is passdb { driver = sql master = yes args = /etc/dovecot/sqlite-master.conf # Unless you're using PAM, you probably still want the destination user to # be looked up from passdb that it really exists. pass=yes does that. pass = yes } with pass=yes, and that causes usera to be validated through both the deny and accept phase of authorisation. In the password_query defined in sqlite-master.conf I user '%u' to locate my master user. Is there any variable I could use to (in that query) to also check that "usera" exists? I could then remove the pass = yes, both to avoid two more queries and to avoid the trap that this account is locked out. Alternatively some other parameter in the passdb segment above to tell the other login to miss the deny stage.

[Dovecot] v2.2.11 released

13 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz.sig I haven't had time to read through the Dovecot mailing list yet, so there are likely some reported bugs that haven't been fixed yet. I'll try to get to them next week in San Francisco. (Probably can't get much done this week in Tokyo.) In the mean time here's v2.2.11 with some new features. + acl plugin: Added an alternative global ACL file that can contain mailbox patterns. See http://wiki2.dovecot.org/ACL for details. + imap proxy: Added proxy_nopipelining passdb setting to work around other IMAP servers' bugs (MS Exchange 2013 especially). + Added %{auth_user}, %{auth_username} and %{auth_domain} variables. See http://wiki2.dovecot.org/Variables for details. + Added support for LZ4 compression. + stats: Track also wall clock time for commands. + pop3_migration plugin improvements to try harder to match the UIDLs correctly. - imap: SEARCH/SORT PARTIAL reponses may have been too large. - doveadm backup: Fixed assert-crash when syncing mailbox deletion.

[Dovecot] can not see public mailbox
by David Mehler 13 Feb '14

Hello, I'm running Dovecot2 and trying to set up public mailboxes. I've got a virtual user system set up with postfix and using MySQL authentication. I'm wanting to create several public mailboxes for shared messages. I've followed the wiki and have the public folder created. I've got a folder /home/vmail/public/public1 public1 being the maildir of the public mailbox. I can see in my folder list of my webmail client the root public folder but I can't change in to it and I can not see the public1 public mailbox. I'm using one user vmail set up for this setup, permissions on the public1 folder allow the vmail user to read and execute. In public1 I have a file dovecot-acl which has the user attempting to access the public folder with the flags l and r. Below is my config with doveconf -n. I'd appreciate any suggestions. Thanks.

[Dovecot] one 2.2.11 POP3 thread is enough
by Reindl Harald 12 Feb '14

why are people starting now every minute a new thread about the same problem already reported as reply of the release announce? -------- Original-Nachricht -------- Betreff: Re: [Dovecot] v2.2.11 released Datum: Wed, 12 Feb 2014 10:05:17 +0100 Von: Ralf Hildebrandt <Ralf.Hildebrandt(a)charite.de> Antwort an: dovecot(a)dovecot.org An: Dovecot Mailing List <dovecot(a)dovecot.org> * Timo Sirainen <tss(a)iki.fi>: > http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz > http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz.sig > > I haven't had time to read through the Dovecot mailing list yet, so there are likely some reported bugs that haven't been fixed yet. I'll try to get to them next week in San Francisco. (Probably can't get much done this week in Tokyo.) In the mean time here's v2.2.11 with some new features. > > + acl plugin: Added an alternative global ACL file that can contain > mailbox patterns. See http://wiki2.dovecot.org/ACL for details. > + imap proxy: Added proxy_nopipelining passdb setting to work around > other IMAP servers' bugs (MS Exchange 2013 especially). > + Added %{auth_user}, %{auth_username} and %{auth_domain} variables. > See http://wiki2.dovecot.org/Variables for details. > + Added support for LZ4 compression. > + stats: Track also wall clock time for commands. > + pop3_migration plugin improvements to try harder to match the UIDLs > correctly. > - imap: SEARCH/SORT PARTIAL reponses may have been too large. > - doveadm backup: Fixed assert-crash when syncing mailbox deletion. pop3 keeps crashing with a sigsegv in that version. Gotta go back.
