[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. Thanks in advance, Nick ====================================================================== # 2.2.12: dovecot.conf protocols = imap pop3 login_greeting = Org POP/IMAP Srv XAPITI XPICTOY mail_location = maildir:~/Maildir/ mail_gid = 500 mail_uid = 500 auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_debug = no disable_plaintext_auth = no mail_plugins = quota notify replication protocol imap { imap_client_workarounds = "delay-newmail" mail_plugins = quota imap_quota notify replication } protocol pop3 { mail_max_userip_connections = 3 mail_plugins = quota notify replication pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = log_path = mail_plugins = quota notify replication postmaster_address = sysadmin(a)example.com sendmail_path = /usr/lib/sendmail } userdb { args = /etc/dovecot/dovecot-usrdb-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap.conf driver = ldap } dsync_remote_cmd = ssh -l root vmail1.example.com doveadm dsync-server -u%u plugin { mail_replica = remote:vmail@vmail1.example.com } plugin { quota = maildir:User quota quota_rule = *:storage=4G quota_rule2 = Trash:storage=+3%% quota_warning = storage=75%% quota-warning 75 %u quota_warning2 = storage=90%% quota-warning 90 %u } service quota-warning { executable = script /opt/mail1.sh user = vmail unix_listener quota-warning { user = vmail } } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { service_count = 1 vsz_limit = 64 M } service pop3-login { service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 } ssl_ca = </etc/pki/tls/certs/chain-1552.pem ssl_cert = </etc/pki/tls/certs/cert-1552.pem ssl_key = </etc/pki/tls/private/key-1552.pem syslog_facility = local1 ======================================================================

[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
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.

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.

[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] %{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

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

[Dovecot] mail-filter cannot work with large email about 700k
by boyd yang 25 Mar '14

25 Mar '14

Hi All I configured dovecot 2.1.7 with mail-filter plugin. It works well for small emails like server k big.(7k) But it failed with larger emails about 700k. The scripts hang out, and the mail-filter-out process does not exist and always in ps. It does not work even I use "cat" in mail-filter-out.sh. Where to set the size limit for mail-filter? Do you know how to fix this? This bug also exists in 2.2.12. Thanks!

[Dovecot] [LMTP] sieve filter does not drop privilleges?
by kjonca＠o2.pl 25 Mar '14

25 Mar '14

I have (user) sieve filter in my home dir. This filter uses "vnd.dovecot.filter" extension to call some shell scripts. These scrips creates some temporary files. Strange thing: whent sieve is called via dovecot-lda - these files are created by user "kjonca" when sieve is called via lmtp - these files are created by root. Is there any way to drop privilleges where lmtp passing messages to sieve? KJ -- http://wolnelektury.pl/wesprzyj/teraz/

[Dovecot] Weird Authentication behaviour

Hi guys, we use dovecot 2.0.9 and authentication against a mysql database. Everything works fine, but we found some weird behavior when the password is e.g. testpass you also authenticate successfully with testpass123 or testpassNOT. Whatever comes after the correct password doesnt matter, the authentication is still successful. Here are the used configs: // auth-sql.conf.ext passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/data/mail/%d/%n } // dovecot-sql.conf.ext driver = mysql connect = host=[IP] dbname=[DB] user=[USER] password=[PASS] default_pass_scheme = CRYPT password_query = SELECT `password`, `login` AS `user` FROM `v_email_accounts` WHERE `login`='%u' // 10-auth.conf disable_plaintext_auth = no auth_mechanisms = plain !include auth-sql.conf.ext // 10-master.conf default_process_limit = 1000 default_client_limit = 3003 default_vsz_limit = 1024M service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 vsz_limit = 1024M } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service lmtp { unix_listener lmtp { } } service imap { vsz_limit = 1024M process_limit = 2048 } service pop3 { process_limit = 2048 } service auth { unix_listener auth-userdb { user = vmail group = vmail } client_limit = 8096 } service auth-worker { } service dict { unix_listener dict { } } Thanks in advance for your help!

[Dovecot] imap: Error: mmap() failed with file ... dovecot.index.cache: Cannot allocate memory
by Urban Loesch 24 Mar '14

24 Mar '14

Hi, since some days (about 10) I get the following error in mail error log many, many times: ... dovecot: imap(user(a)domain.com pid:32769 session:<dszL7lX1xADD/uGI>): Error: mmap() failed with file /home/dovecotindex/domain.com/user/mailboxes/Trash /dovecot.index.cache: Cannot allocate memory .... 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. I checked the size of the index cache file and it seems very big: total 2,7G -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index.backup -rw------- 1 mailstore mailstore 2,7G Mär 24 14:19 dovecot.index.cache -rw------- 1 mailstore mailstore 140 Mär 24 14:45 dovecot.index.log -rw------- 1 mailstore mailstore 89K Mär 24 14:36 dovecot.index.log.2 About 2,7 GB? To solve the problem temporarily, I removed the index files from the index Trash folder and Dovecot initialized an index rebuild. Now the size of the index files are small: total 28K -rw------- 1 mailstore mailstore 512 Mär 24 14:47 dovecot.index -rw------- 1 mailstore mailstore 20K Mär 24 15:28 dovecot.index.cache -rw------- 1 mailstore mailstore 1,2K Mär 24 15:28 dovecot.index.log But why could the index cache file be so big? Many thanks Urban

[Dovecot] Dovecot/Django authentication
by Thomas Johnson 24 Mar '14

24 Mar '14

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. IMAP Request: A2 CREATE Inbox/63 IMAP Response: A2 NO [ALREADYEXISTS] Mailbox exists. If I login manually and do 'LIST "" INBOX/63' it works fine, but not with "Inbox/63". 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] 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?

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

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

19 Mar '14

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

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

18 Mar '14

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

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

15 Mar '14

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