Hi everybody, I'm trying to backup a dovecot instance, and i'm looking for a method to "snapshot" dovecot maildir in a properly way, and backup whole snapshot in a second step (tar). I read about dsync, end, if i'm not going wrong, it dumps correctly also dovecot indexes; is it the tool i need? Thank you for any hint. Ramon

[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

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
by Spyros Tsiolis 28 Mar '14

28 Mar '14

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. It could happen when client and server disagree on using STARTTLS or SSL, so hardwiring your client to use whatever your server supports stops the client from fumbling around (and getting it wrong). > Given my experience with all this, I feel confident that Thunderbird is not > a factor in the problem.

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.

I have two users working fine. Tried to add a third and it refuses to accept log on details. I've stripped everything back to default config, and still only the first two users are accepted! Can't understand it and it's driving me crazy. I've deleted and created the user a thousand times, and opened the config up as wide as possible. I'm obviously doing something stupid but what! # OS: Linux 3.2.0-4-686-pae i686 Debian 7.2 auth_mechanisms = plain login digest-md5 rpa base_dir = /var/run/dovecot/ disable_plaintext_auth = no login_trusted_networks = 10.0.0.0/8 passdb { driver = pam } protocols = imap service auth { user = root } ssl_cert = </etc/ssl/certs/server.pem ssl_key = </etc/ssl/private/mail.key userdb { driver = passwd } -- View this message in context: http://dovecot.2317879.n4.nabble.com/Authentication-woes-passwd-standard-in… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot replication, no updates on message deposit
by Milan Cvetkovic 27 Mar '14

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] Help connecting from remote client (no auth attempts)
by Blake McBride 27 Mar '14

27 Mar '14

Greetings, I am running 64 bit Ubuntu server 10.04.04, postfix 2.7.0, and dovecot 1.2.9. I installed the dovecot-postfix package so the two would be configured to work together. >From localhost I can send and receive email to/from arbitrary remote sites without any problems. I wish to send & receive email from my (remote) desktop via Thunderbird through that sever. When I attempt to configure Thunderbird I get the following on mail.log: Mar 26 15:04:51 booklion dovecot: imap-login: Aborted login (no auth attempts): rip=74.179.230.177, lip=192.168.168.53 Mar 26 15:04:51 booklion dovecot: last message repeated 2 times Mar 26 15:04:51 booklion dovecot: pop3-login: Aborted login (no auth attempts): rip=74.179.230.177, lip=192.168.168.53 Mar 26 15:04:51 booklion dovecot: last message repeated 3 times Mar 26 15:04:51 booklion dovecot: imap-login: Aborted login (no auth attempts): rip=74.179.230.177, lip=192.168.168.53 ...

[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

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.

I was under the impression that INBOX was not case-sensitive. Is this a bug or is the client doing something silly?

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

24 Mar '14

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

[Dovecot] Where can I find a stable PPA?

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

Hello all, I was wondering which version is better for Centos v6.x. CentOS v6.5 comes with dovecot v2.0.9 as default. Should I go ahead with this or go for the latest ? (v2.2.10 / v2.211 / v2.2.12, btw what's the diferrence between the three ?) s.

[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

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

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.

[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] Patch & feature request: hide passwords in doveconf -n by default

[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

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?
by Tommy Berglund 12 Mar '14

12 Mar '14

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] Suppress IMAP Disconnection Messages
by Ron Scott-Adams 12 Mar '14

12 Mar '14

In syslog, I frequently see messages such as: "dovecot: imap(user): Disconnected for inactivity" I understand why these happen, but is there anyway to configure logging to suppress these messages?

[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

I am working on setting up dovecot 2.2.12 with an installed qmail + vpopmail 5.5.0 base. So far I have not had much luck getting the auth to work with vpopmail. Does dovecot 2.2.12 work with vpopmail 5.5.0? So far when I try to authenticate I always get back User Unknown in the log. Thanks

[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] BUG: segmentation fault in auth

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

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 ? Thanks, Regards, Stan. --------------------------------------------------------------- Stanislas SABATIER s.sabatier(a)pobox.com ---------------------------------------------------------------

[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
