Newbie why is dovecot classified diff then sendmail or courier
by David Niklas 29 Sep '15

29 Sep '15

Hello, this is probably a dumb question, but I can't for the life of me figure out why sendmail and courier are classified universally as network-mail-mta whereas dovecot is in places like network-mail-general or some such place. I've used several Linux distros and have noted this keenly (they also normally classify photorec, the HD recovery tool as hardware-photography,so this may just be a mistake). I'm concerned that I'm looking into the wrong software for an mail transport/delivery agent. Thanks, David

doveadm fetch line wrapping
by Peter Chiochetti 28 Sep '15

28 Sep '15

The manual at http://wiki2.dovecot.org/Tools/Doveadm/Deduplicate tells how to estimate what will be expunged: > doveadm -f table fetch -u jane 'guid uid' mailbox a_Box | sort I wanted to learn the subjects: > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box In the output, long lines will be broken up, continuation lines starting with a blank (mostly), disabling the sort > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box \ > | sed -e :a -e '$!N;s/\n\s//;ta' -e 'P;D' | sort --stable Some (gnu) sed foo joins them back together, the sort works again :) -- peter

Hi, I have been using dovecot for multiple years, without a problem so far. I'm running version 2.0.19-0ubuntu2.2. A few weeks ago, the following problem started. When sending an e-mail with Thunderbird, the message is saved to the "Sent" IMAP folder after sending it out. Every few days, this

Sieve and forward
by Il Neofita 28 Sep '15

28 Sep '15

Hi I have already posted to the postfix group, however, I believe that sieve and dovecot should be able to fix this problem. When I receive a message from yahoo and the user forward it to a gmail or yahoo acount this email is considered as spam or rejected. >From yahoo is rejected since it seems that I am try to send spam since the email should be signed with dkim. Is there a way to encpuslated or sign in some way. Thank you

dovecot, fts, solr5 patch, fuzzy search
by Sergey Urushkin 28 Sep '15

28 Sep '15

Hi! I have a patch and several thoughts about FTS in dovecot. I. SOLR v5.1 and above doesn't allow GET /select queries with Content-Type header set, so, I just removed it from the code: --- dovecot-2.2.18/src/plugins/fts-solr/solr-connection.c 2015-05-13 17:14:45.000000000 +0300 +++ dovecot-2.2.18.patch/src/plugins/fts-solr/solr-connection.c 2015-09-27 19:47:40.363843359 +0300 @@ -432,7 +432,6 @@ solr_connection_select_response, conn); http_client_request_set_port(http_req, conn->http_port); http_client_request_set_ssl(http_req, conn->http_ssl); - http_client_request_add_header(http_req, "Content-Type", "text/xml"); http_client_request_submit(http_req); conn->request_status = 0; After that it works just fine. And it seems it doesn't hurt compatibility with older versions. Tested with 3.1, 3.6.2, 4.10.4, 5.3.1 So, I think this patch should be included. II. Fuzzy search. As I understand dovecot searches the same way despite FUZZY word is given or not. In my case I'd like to have an ability to make lookups like "domain.com usernamepart" (usernamepart - part of localpart). So, I use '<str name="defType">edismax</str><int name="qs">15</int>' inside requestHandler /select in solrconfig.xml. It's very convenient for users. Besides other things, this makes searches "abc@def" and "def@abc" identical to dovecot. But the problem is that sometimes the exact match is necessary. E.g. when using "doveadm expunge". For now I found a workaround - remove fts plugins while using doveadm with -o "`dovecot -n | sed -n 's/"//; s/ *= */=/; /^mail_plugins/s/$"\| fts\(\|_[^ ]\+$\)//gp'`". But I think users should have an ability to decide which search type to use. Here is what I'm suggesting: 1. Implement fts_fuzzy_default option (default - true, current behavior). false should disable fuzzy search by default. 2. Make a way for fts backend to choose which search type to use. For solr it would be an ability to specify: a) "handler" (default=select) and "handler_fuzzy" (default=select or handler's value) (the same as handler by default). After this you have to create second select-like handler with fuzzy capabilities in solrconfig.xml. Example: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ handler=select handler_fuzzy=select2 This method will use the same index for both search types. b) "url_fuzzy" URL (different solr core or even address/port), like this: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ url_fuzzy=http://127.0.0.1:8983/solr/dovecot_fuzzy/ This method will allow to have two completely different indexes. And according to RFC 6203 search query generally may be mixed (FUZZY/EXACT). Both options will be useful in different setups. Hope, these thoughts will help. -- Best regards, Sergey Urushkin

v2.2.19 release candidate released
by Greg Wildman 28 Sep '15

28 Sep '15

Hello, I am trying out 2.2.19.rc1 on a lightly loaded server with no problems so far. The reason I wanted to try 2.2.19.rc1 was to get access to the %{listener} variable in the auth phase so I can modify the SQL password_query according to which unix_listener is being queried. According to the docs, "These variables work only in Dovecot-auth and login_log_format_elements setting". I can confirm that %{listener} works in login_log_format_elements but it does not work if I use it in my SQL auth query. My logic is as follows: I create multiple listeners for different SASL authentications in 10 -master.conf service auth { unix_listener auth-userdb { mode = 0660 user = dovecot group = vmail } unix_listener exim-client { mode = 0660 user = dovecot group = exim } unix_listener xmpp-client { mode = 0660 user = dovecot group = mail } user = $default_internal_user } Now I want to use %{listener} in my SQL password_query in a case statement to auth according to which listener is being used. E.g. CASE '%{listener} ' \ WHEN 'exim-client' THEN ma.SMTPAUTH_allowed = 'YES' \ WHEN 'xmpp-client' THEN ma.XMPP_allowed = 'YES' \ ELSE ma.IMAP_allowed = 'YES' \ END Should the %{listener} variable work in this case ? -- Greg

modify message with doveadm?
by Frank-Ulrich Sommer 27 Sep '15

27 Sep '15

Hello, I'm using dovecot with getmail and spamassassin. To re-learn false detected mails I created two folders and use an external script that checks the corresponding maildir directories for changes (with inotifywait). The mails found in these directories are passed to sa-learn (to re-learn the correct classification) and then moved back to the inbox or the spam folder. To access the mail I use "doveadm search" (to find all mails in the two folders), "doveadm fetch" (to get the text and pass it to sa-learn) and "doveadm move" (to move the mail to the correct location. This works as desired, except that a mail once marked as spam will forever be marked as such. Spamassassin has the -d option to remove the markup, but I need to replace the original mail with the cleaned version. The only idea I got was deleting that mail and importing the cleaned one, but as I want to implement several "special" folders for further functionality with different IMAP clients I would prefer a "cleaner" solution. What would be the correct/best way to modify the mail body/header/text from an external tool? Kind regards, Frank

Hi All! I'm also hitted by this problem. I'm trying to migrate emails from very old dbmail to dovecot (maildir). I read old threads with similar problem but I found only such solutions: - upgrade to 2.2.13 - workarround : use imapsync - no solution I'd like to not use imapsync, have you got an idea what should I

Sieve - multiple cores/CPUs
by Paweł Grzesik 25 Sep '15

25 Sep '15

Hi All, I have a quick question about the Sieve in Dovecot. I know that this is a plugin so probably it depends on the Dovecot itself but: is it able to use multiple cores/CPUs when doing the filtering? does the filtering for each mail user run on a separate core? Thanks, Pawel

Cyrus mailbox (plain files) to Dovecot
by Wolfgang Rosenauer 25 Sep '15

25 Sep '15

Hi, I'm migrating from a Cyrus to a Dovecot installation right now. As part of it I've got plain Cyrus mailboxes (w/o real metadata; so to say I've got the /var/spool/imap/user part but not the /var/lib/imap/user one)). Those former mailboxes I want to provide under a public namespace via ACLs. The question I cannot answer right now is: How can I convert these plain mailboxes on a FS level to maildir++ so I can provide them as public mailboxes on the new system? The tools I have found require a valid/complete cyrus mailbox. (I don't really care about message flags etc). Thanks, Wolfgang

v2.2.19 release candidate released
by Timo Sirainen 25 Sep '15

25 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz.sig A lot of changes since v2.2.18, so here's a release candidate first. If no bugs are reported, I'm planning on making the final release sometimes this week. The most interesting new features here are the imap-hibernate process, quota count backend and director/proxy improvements. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added support for imap-hiberanate processes. + Optimized tracking mailboxes' vsizes (= sum of all messages' size). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

dovecot --hostdomain issue
by dovecot＠outputservices.com 25 Sep '15

25 Sep '15

I am on a server I called "email. But dovecot says i am on sunfire.outputservices.com ------------------------------------ dovecot --hostdomain sunfire.outputservices.com ------------------------------------ I would like to at least get it to say email.outputservices.com.

Released Pigeonhole v0.4.9.rc1 for Dovecot v2.2.19.rc1
by Stephan Bosch 25 Sep '15

25 Sep '15

Hello Dovecot users, Here's the Pigeonhole RC that goes with the Dovecot RC. Changelog v0.4.9.rc1: * Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins. This will prevent plugin ABI mismatches. + Implemented a vnd.dovecot.environment extension. This builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox. It also creates a variables namespace so that environment items can be accessed directly. I am still thinking about more environment items that can be added. + Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable. This can be configured separately for each of the three extensions. + ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to pass client information to the back-end. - ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command. - doveadm sieve plugin: Fixed incorrect initialization of mail user. This caused a few memory leaks. - sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder. This caused message duplication. - lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the optimal line length caused empty lines in the output, which would break the resulting message header. This surfaced in References: headers with very long message IDs. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

24 Sep '15

Hello, Im getting problem on FTS on new created folders (mailboxes). How to simulate: - Enable FTS (solr on our case) - Create a new folder (mailbox) - Move some message to that mailbox - Try to search for the message contents *doveadm search -u user@domain text sometext* # Found nothing, but if i move the message to another mailbox, the search catch the message. # I tried doveadm index command but no response as well # This works only after a full fts rescan *doveadm fts rescan -u user@domain* # And now, works *doveadm search -u user@domain text sometext3c7b60241443ba55af680000cc4d0d4b 1* # My dovecot version = 2.2.18 (EE) # My fts config: fts = solr fts_autoindex = yes fts_autoindex_max_recent_msgs = 50 fts_solr = url=http://127.0.0.1:8080/solr/ Anyone got this problem?

dict lookup from quota plugin
by Bjørnar Ness 23 Sep '15

23 Sep '15

I am having trouble with using a custom daemon listening on a socket together with the quota plugin. My configuration is: quota = dict:User quota::dict:/tmp/dovecot-proxy-dict:: The problem is that dovecot sends keys without usernames, for example: priv/quota/storage Is it possible to get around this limitation without code modification? Also, is it planned to support the "new-style" userdb/passdb lookups from other plugins? -- Bj(/)rnar

bug - over system quota and dovecot-uidlist
by krzf83＠gmail.com 23 Sep '15

23 Sep '15

Ever since I've migraded from courier pop3 to dovecot pop3 I'm constantly getting complains from users that went over system quota for short while and then their pop3 client downloads all messages again. I never happened with courier pop3. I think that dovecot does not handle dovecot-uidlist file safely so it can withstand such situations. rsync and other similar programs always writes to a copy of the file like dovecot-uidlis.xcb453 and on success unlinks old file and renames new one. Dovecot should not assume that write operation on dovecot-uidlist will succeed. Yes, I know I can put metadata like dovecot-uidlist somewhere else, on another partition but that really splits mailbox into multiple locations making for example backups way harder to make, restore, share etc.

Dovecot proxy ignores trusted root certificate store
by Alex Bulan 22 Sep '15

22 Sep '15

Dovecot v2.2.18 OS: FreeBSD 10.1/amd64 Dovecot in proxy mode ignores the root certificate store and can't verify the backend's SSL certificate. I've pointed ssl_client_ca_file to my root certificate store, but I suspect ssl_client_ca_file is only used in imapc context. It seems to be ignored in proxy context. doveconf -n ssl_client_ca_file: ssl_client_ca_file = /usr/local/share/certs/ca-root-nss.crt In my password_query I return host set to the backend's IP address, starttls='yes', proxy='y'. The backend's certificate chain is correct and it verifies successfully with "openssl s_client -connect x.x.x.x:110 -starttls pop3 -CAfile /usr/local/share/certs/ca-root-nss.crt". But the Dovecot proxy fails to verify the intermediate certificate it receives from the backend. The inode atime of ca-root-nss.crt is never updated, either at Dovecot start or when it connects to the backend, so Dovecot (via the openssl library) never reads the file.

2.2.18 Regression: Incorrect STATUS response for virtual mailboxes
by Guilhem Moulin 22 Sep '15

sieve_extprograms - run any individual script?
by Hajo Locke 22 Sep '15

22 Sep '15

Hello, i use sieve extension sieve_extprograms to send incoming mail to some script. For security reasons it is needed that script-paths etc. are registered in dovecot.conf This is my current dovecot.conf plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } .dovecot.sieve example: if address "to" "test(a)example.com" { filter "myfilter"; } This is all working without problems. Is there a possibility to allow users the execution of individual scripts in own homepath? Some people need to pipe mails to scripts for immediately processing (some ticketsystems need this). Is there a way to make this possible with sieve? Thanks, Hajo

Multiple passwords for a user (SQL)
by Marco Fretz 22 Sep '15

22 Sep '15

Hi everyone, I'm not sure if this has been discuessed already as I coun't find anything in the archives - maybe I'm looking for the wrong thing. I want to build something similar to googles "app passwords" where your use a different password (strong, auto generated) for each device / app. In general I think this is pretty easy on the database side as I just need a password table and link say the passwords with an user_id to the corresponding user in the users table - one use has many passwords (1:n). for dovecot this means that it will get multiple rows with passwords back from the "password_query". is there a way to tell dovecot to check all those returned passwords and "pass" the request if one of those passwords match? thank you, best regards Marco

[Dovecot] Pigeonhole sieve re-filter extension?
by T.B. 22 Sep '15

22 Sep '15

Dear Stephan Bosch, dear Dovecot community, "sieve-filter" re-filtering of existing mails is already a great progress for everyone using sieve! But as far as I know this functionality is just accessible by the server administrator. In the meanwhile everyone knows the comfort of re-executing filter scripts on his own existing mailboxes - triggered by himself! This service is already very widespread. Examples are MUA's like Outlook or Thunderbird which provide this service just on the client side. Or almost every web-mail provider offers this. Is there already an managesieve protocol extension that allows client triggered server side re-filtering? If not, maybe you could design a RFC for this? What do you think? Best regards. T.B.

ssl_key_password loaded from file: 'Couldn't parse private ssl_key'
by B. R. 22 Sep '15

22 Sep '15

As this is my first message to this ML: Hello! I am using a password-protected SSL key for my dovecot MDA. When I tried to use the ssl_key_password configuration directive as follow: ssl_key_password = </path/to/passfile it did not work as I logged the following: dovecot: imap-login: Error: SSL: Stacked error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt dovecot: imap-login: Fatal: Couldn't parse private ssl_key: error:0906A065:PEM routines:PEM_do_header:bad decrypt However, not using the fille inclusion but directly configuring as follow: ssl_key_password = mypass did work... I am loading my certificate & key with the file inclusion trick... How come cannot I use that for the password file? It would avoid input the password directly into the dovecot configuraiton files, forcing me to change permissions and duplicating it... When renewing the private key I will be force to edit the password at every location. Is it a bug? or a feature? :D --- *B. R.*

Messages lost from imap folders
by Nikolaos Milas 19 Sep '15

19 Sep '15

Hello, We have one user who is complaining that he has lost mails from 3 imap folders, administered through squirrelmail. The folders suddenly appeared unregistered, and once manually registered they were empty. Has anyone observed something like this? We are running two servers (as VMs) with Dovecot v2.2.18, synced (two-way) using dsync. The configurations follow. Can you please help me understand what may have gone wrong? Can I try to find actions regarding these folders in the logs? What should I search for? Could this be an issue involving dsync? How can I trace back dsync activity in detail? Server configs follow (I have only altered the real domain name and the login greeting.)

Is there a way to restrict my user logins from a set of IPs? For example, all my users are in the US so there shouldn't be any logins from other countries. Can I tell dovecot to restrict logins to a CIDR list of US IPs? Can someone point me to docs on how to set this up? I've searched but haven't found how to accomplish this. Thanks, -Terry Terry Barnum digital OutPost http://www.dop.com

New created users can not log in
by Ferdinand Gruber 17 Sep '15

17 Sep '15

Hi, I am using dovecot 2.2 for some time. All users on the system can log in using Horde Webmail. But now, after creating a new user on the server with <useradd -m username> this new user is not able to log in. Of course I have set a password for the new user. In the log file I can see: Sep 16 23:04:05 servername auth: gkr-pam: error looking up user information Sep 16 23:04:07 servername HORDE: [imp] [login] Authentication failed. [pid 1584 on line 730 of "/srv/www/htdocs/horde/imp/lib/Imap.php"] Sep 16 23:04:07 servername HORDE: [imp] FAILED LOGIN for calendar (93.82.157.132) to {imap://localhost/} [pid 1584 on line 157 of "/srv/www/htdocs/horde/imp/lib/Auth.php"] Sep 16 23:04:07 servername HORDE: [horde] FAILED LOGIN for calendar to horde (93.82.157.132) [pid 1584 on line 199 of "/srv/www/htdocs/horde/login.php"] Please give me a hint. -- Ferdinand

How to "Windows Authenticate"
by Mark Foley 17 Sep '15

17 Sep '15

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server. I have been using auth_mechanisms plain login, and passdb driver = shadow. What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients. If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful. Here is my current config: $ doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/c5fe0cc8242d6030.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/mail.ohprs.org.key userdb { driver = passwd } verbose_ssl = yes Thanks, Mark Foley

FreeBSD 10 & default_vsz_limit causing reboots?
by Rick Romero 15 Sep '15

15 Sep '15

Ok, So this is really more of an observation than anything else. I had a FreeBSD 10.1 server that was running great. Some SSL issue came up, or I upgrade Dovecot in ports - something occurred and the machine started rebooting randomly. It would run for 2 weeks, then reboot. It might run for 5 days and then reboot. So I started doing more FreeBSD upgrades, thinking it was a kernel issue. The reboots only increased. This weekend I started thinking I might actually be having hardware issues. But, since I don't have easy physical access to the box and it's REALLY under loaded, I figured what the hell and upraded to 10.2 on Sunday. I think it rebooted 4 times after that on Sunday, and then another 2 times Monday morning. Its worth noting that while I have crash dumps enabled, they don't seem to be occurring. So hardware is still a possibility. After the 2nd Monday morning reboot, I started to wonder if there was some sort of process issue. Besides the OS upgrades - I had been monitoring the Dovecot logs for when the process limits are reached, and increasing them. It's a 'big' box, and load is typically between .30 and .50. CPUs aren't overtaxed, and most of the memory is dedicated to ZFS. The reboots are so short, I've only received one 'down' alert due to them. So it's a conerning issue, but not really impacting production. On a whim I changed my default_vsz_limit (as I had been increasing every other limit but that) from 384M to 512M. The system hasn't rebooted in 24hours. Now that could be a coincidence, but I thought I'd at least put it out there. If you see anything weird in my dovecot config, let me know - My config was originally vpopmail, but over time I've migrated to SQL-only. root@romulus:/usr/local/etc/dovecot # dovecot -n # 2.2.18: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.2-RELEASE amd64 auth_master_user_separator = * auth_mechanisms = plain login auth_username_translation = %@ auth_verbose = yes default_login_user = dovecot default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 log_path = /dev/stderr login_greeting = Ready. login_trusted_networks = 172.16.100.0/24 mail_fsync = never mail_plugins = " quota zlib stats" mail_privileged_group = mail namespace compat { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-master-sql.conf driver = sql master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=+10%% stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service anvil { client_limit = 3175 } service auth { client_limit = 3684 unix_listener auth-master { mode = 0600 } } service imap-login { process_limit = 1536 process_min_avail = 25 service_count = 1 } service imap-postlogin { executable = script-login rawlog /usr/local/etc/dovecot/lastauth-imap.sh user = vpopmail } service imap { executable = /usr/local/libexec/dovecot/imap imap-postlogin process_limit = 1536 } service pop-postlogin { executable = script-login /usr/local/etc/dovecot/lastauth-pop.sh user = vpopmail } service pop3-login { process_limit = 1536 process_min_avail = 15 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 pop-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } shutdown_clients = no ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/mail.key ssl_key_password = na userdb { driver = prefetch } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_max_userip_connections = 100 mail_plugins = " quota zlib stats imap_zlib quota imap_quota" } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Dovecot does not accept new connection with error "imap-login: Error: read(anvil) failed: EOF"
by Julien Fastré 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, First of all, thank you for the work the contributors are doing with Dovecot ! Dovecot is doing a great job ! I am encountering a problem with a configuration and, despite my search on the web, I do not find any solution for this problem. Dovecot seems to stop accepting new connection. The users : - - can not save sent messages to "Sent" folder (using Thunderbird) ; - - can not connect or retrieve message from webmail (using sogo or roundcube) In the log, I see this error : > Jun 30 13:54:53 mail dovecot: imap-login: Error: read(anvil) > failed: EOF Jun 30 13:54:53 mail dovecot: message repeated 2 times: > [ imap-login: Error: read(anvil) failed: EOF] (the message may be repeated more than 2 times) It happens... sometimes. Manually restarting the dovecot service make the software working again. By searching on the web, I regularly see this statement in logs : > dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF like here : http://www.dovecot.org/list/dovecot/2010-November/054694.htm l But it doesn't seem to be the same problem as mine (anvil / anvil-auth-penalty). The problem happens during peak load. Sometimes it happens twice a week, sometimes it may spent two month without any problem (during holidays, I did not had any problem). My configuration : > # doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux > 3.13.0-49-generic x86_64 Ubuntu 14.04.3 LTS login_trusted_networks > = 10.0.3.0/24 mail_location = mbox:~/mail:INBOX=/var/mail/%u > mail_plugins = quota acl 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 { list = children location > = maildir:/var/mail-data/vhosts/%%u:INDEX=~/shared/%%u prefix = > shared/%%u/ separator = / subscriptions = no type = shared } > namespace inbox { inbox = yes location = mailbox Drafts { > special_use = \Drafts } mailbox Junk { special_use = \Junk } > mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { > special_use = \Sent } mailbox Trash { special_use = \Trash } prefix > = separator = / type = private } passdb { driver = pam } passdb { > args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { > acl = vfile acl_shared_dict = > file:/var/mail-data/acl_db/shared-mailboxes quota = maildir:User > quota quota_grace = 10%% quota_rule = *:storage=2G quota_rule2 = > Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } > postmaster_address = julienfastre(a)cvfe.be protocols = " imap lmtp > sieve" service auth { unix_listener > /var/spool/postfix/private/dovecot-auth { group = postfix mode = > 0660 user = postfix } } service lmtp { unix_listener > /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = > 0600 user = postfix } } ssl_ca = </etc/dovecot/certificates/ca.pem > ssl_cert = </etc/dovecot/certificates/mail.cert.pem ssl_key = > </etc/dovecot/certificates/mail.key.nopass.pem userdb { driver = > passwd } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver > = ldap } protocol lmtp { mail_plugins = quota acl sieve } protocol > imap { mail_max_userip_connections = 30 mail_plugins = quota acl > imap_quota imap_acl } As somes answer about anvil-auth-penalty may suggest it is linked with proc capabilities, this is the limitation of the /proc > root@mail:/home/ubuntu# ps -aux | grep anvil postfix 4568 0.0 > 0.0 27404 1596 ?

Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain). This is using "hosts = dc03.domain:3268": ------------------------------------------------ [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 0 0 <dovecotServer_IP>:58485

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo

Problems setting up SIS (duplicate files with same hash)
by Joe Beaubien 09 Sep '15

09 Sep '15

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the emails I sent with the same attachment, I got 3 seperate files with the same hash name but a different string following the dash: -rw------- 1 info info 2.6M Sep 5 11:14 e35083e3280a21c6aaabbae8cb23d54493f514a5-6a22711a7b05eb5509480000045c9bf4 -rw------- 1 info info 2.6M Sep 5 11:16 e35083e3280a21c6aaabbae8cb23d54493f514a5-6c22711a7b05eb5509480000045c9bf4 -rw------- 2 info info 2.6M Sep 5 11:18 e35083e3280a21c6aaabbae8cb23d54493f514a5-6e22711a7b05eb5509480000045c9bf4 drwx------ 2 info info 4.0K Sep 5 11:18 hashes For the record, the "hashes" subfolder has only 1 hash (e35083e3280a21c6aaabbae8cb23d54493f514a5) which perfectly matches the first part of the 3 filenames. *2) Saving attachments under a generic name or more flexible permissions?* It seems that dovecot saves the attachment with the username and group of the user who has received the email. Is it possible to have dovecot save the attachments as a generic user (like dovecot or dovenull) so that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

Dovecot and IPA
by Kanwar Ranbir Sandhu 08 Sep '15

08 Sep '15

Hello, I'm trying to get Dovecot to use GSSAPI for authentication. I have an IPA server on CentOS 7 with a bunch of my servers attached to the IPA domain, including the server running Dovecot. I've followed official documentation from Red Hat and read numerous wiki articles on how to configure Dovecot to get it to use GSSAPI correctly. I don't think I've done anything incorrectly, but it refuses to work. This is the error I'm seeing: mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM> I don't understand why no username is being passed. My mail client is Evolution 3.10.4. FYI, Dovecot does work fine using a user/password file. I'm just trying to switch it over to GSSAPI so that I can manage passwords from one system. Any help would be appreciated. Regards, Ranbir -- Kanwar R.S. Sandhu

Multiple vacation
by Michele Locati 08 Sep '15

08 Sep '15

Hi all I'm using Dovecot 2.2.9 and I'm having problems configuring multiple vacation actions. The problem is that I'd like to have two different senders and two different messages, selecting the correct case by the recipient email address. I mean, if someone writes me to my email address "to-address1(a)example.com" I'd like to answer from "from-address1(a)example.com" with the message "TEST 1". If someone writes me to my email address "to-address2(a)example.com" I'd like to answer from "from-address2(a)example.com" with the message "TEST 2". Here's my script: require ["fileinto","vacation"]; vacation :addresses ["to-address1(a)example.com"] :from " from-address1(a)example.com" text: TEST 1 . ; } vacation :addresses ["to-address2(a)example.com"] :from " from-address2(a)example.com" text: TEST 2 . ; But the vacation filter doesn't work, and I see this message in the log file: main script: line X: error: duplicate vacation action not allowed (previously triggered one was here: main script: line Y). Is there a way to allow multiple vacation actions? Thank you Michele

Public folder subscriptions with Outlook
by Paul Tansom 08 Sep '15

08 Sep '15

This is more an Outlook issue than Dovecot, but given that it is connected to Dovecot I figured there would be a good pool of knowledge here that increases the likelihood that somebody knows the answer :) I have a Dovecot server setup with a public folder and keep getting complaints that Outlook users don't see new folders created by other people. In Thunderbird it is simply a case of unchecking the box to only show subscribed folders, but I can't find a way to do this in Outlook. The only thing I can think of is putting a script on the server to check for new folders and update each users subcriptions file, but I'm not completely happy with that solution! Any suggestions welcome. -- Paul Tansom | Aptanet Ltd. | https://www.aptanet.com/ | 023 9238 0001 Vice Chair, FSB Portsmouth & SE Hampshire Branch | http://www.fsb.org.uk/ ============================================================================= Registered in England | Company No: 4905028 | Registered Office: Ralls House, Parklands Business Park, Forrest Road, Denmead, Waterlooville, Hants, PO7 6XP

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Fetch command response questions
by Vlad Pop 08 Sep '15

08 Sep '15

Hello, I have the following issue: When using command FETCH 2 (BODY.PEEK[HEADER] UID INTERNALDATE FLAGS BODYSTRUCTURE) on 2 different emails, we get 2 different response structure. First response structure contains the BODYSTRUCTURE in a single line, while in the second response, the BODYSTRUCTURE is divided into multiple lines with "{61}" character at the end of each line. The difference between those 2 emails is the name of some attachments. The attachment is an .eml file named "Re: [SR-Users] Keep-Alive in dialog "freeing a free fragment"" Is this a sort of bug or is it correct to receive the BODYSTRUCTURE on multiple lines? Vlad Pop

segfault when using zlib module with glibc 2.22
by Florian Pritz 08 Sep '15

08 Sep '15

Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear to be fixed yet. The segfault also happens with other commands like `doveadm purge`. Do you need any more information to reproduce and fix this?

File permissions: system groups for do not work for group/shared mailboxes
by Jens Kirchner 08 Sep '15

08 Sep '15

Hello! I am struggling to set up a group mailbox for users of a certain system group. I want to grant access to the mailbox on a filesystem mode by using the system groups. The problem, the set up works fine and when I use setfacl and grant permissions too each user manually, it works fine. However, I want to use a system user's group membership in order to grant access to these mailboxes insted of manually granting for each user. dovecot version: 2.2.9 This is the config part: namespace { location = maildir:/data/mail/public:LAYOUT=fs prefix = GROUP-MAILBOXES/ separator = / subscriptions = no type = public } ... passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ... userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } filesystem permissions (getfacl): # file: GroupboxA/ # owner: root # group: root user::rwx user:user1:rwx group::rwx mask::rwx other::--- default:user::rwx default:user:user1:rwx default:group::rwx default:mask::rwx default:other::--- # file: GroupboxB/ # owner: root # group: root user::rwx group::rwx group:group1:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:group1:rwx default:mask::rwx default:other::--- user1 is in roup1 When setting username-based permissions (GroupboxA), the mailbox is usable and subsribable; when setting groupname-based permissions (GroupboxB) it is not subscribable/usable. Thanks for your help in advance and best regards, Jens

bug in acl_defaults_from_inbox option
by Marco Giunta 08 Sep '15

08 Sep '15

Hi at all, there is a bug in in acl_defaults_from_inbox option: if you define it with ANY value ('yes', 'no', 'whatyouwant', 'xxx') it acts like the value is ALWAYS 'yes', and Dovecot enable it; the only way to disable it, is comment it or delete from configuration file. With 'acl_defaults_from_inbox = no', or 'acl_defaults_from_inbox = whatyouwant', all my folders get ACLs from INBOX; in my case I want to only share INBOX, but also all other folders were shared. When you comment 'acl_defaults_from_inbox', Dovecot works like expected.

Patch for "doveadm -f table" nit (was Re: Dovecot current number of connections being used.)
by Joseph Tam 08 Sep '15

08 Sep '15

> doveadm who -1 2>/dev/null | wc -l You have to redirect stderr to /dev/null because that's where the first header line is written to. The default format style (table) is inconsistent with the other formats (flow,pager,tab) that write headers and data to stdout. The following patch will pick this nit. This patch will require modifications to scripts that rely on doveadm writing headers to stderr.

Dear, use our static analysis tools, I find some bugs (Null deference pointer) for dovecot-2.2.18. Null deference pointer bugs often make program crashes, Please confim them, Thanks! 1. dovecot-2.2.18/src/config/config-request.c 332 'setting_export_section_name(ctx->prefix, def, children[i], i);', pointer 'children' in line 202 assigned NULL and if branch 'case SET_DEFLIST_UNIQUE' not execute, so pointer 'children' is always NULL. It load to a bug of null deference pointer In line 332.

RFC 5465 (NOTIFY) violation: missing HIGHESTMODSEQ in initial STATUS responses
by Guilhem Moulin 08 Sep '15

08 Sep '15

Quoting RFC 5465 (NOTIFY): “If the NOTIFY command enables MessageNew, MessageExpunge, AnnotationChange, or FlagChange notifications for a mailbox other than the currently selected mailbox, and the client has specified the STATUS indicator parameter, then the server MUST send a STATUS response for that mailbox before NOTIFY's tagged OK. […] If either AnnotationChange or FlagChange are included and the server also supports the CONDSTORE [RFC4551] and/or QRESYNC [RFC5162] extensions, the STATUS response MUST contain UIDVALIDITY and HIGHESTMODSEQ.” — https://tools.ietf.org/html/rfc5465#section-3.1 While unsolicited STATUS responses include HIGHESTMODSEQ indeed, the initial STATUS responses (caused by the presence of the STATUS indicator) do not: ~$ /usr/lib/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 … CONDSTORE QRESYNC … NOTIFY SPECIAL-USE] Logged in as guilhem a ENABLE QRESYNC * ENABLED QRESYNC a OK Enabled (0.000 secs). b NOTIFY SET STATUS (SUBSCRIBED (MessageNew MessageExpunge FlagChange)) * STATUS INBOX (MESSAGES 9069 UIDNEXT 109398 UIDVALIDITY 1312585007 UNSEEN 0) […] b OK NOTIFY completed (0.008 secs). [time passes… a new message is delivered to INBOX] * STATUS INBOX (MESSAGES 9070 UIDNEXT 109399 UNSEEN 1 HIGHESTMODSEQ 22216) This defeats the purpose of the STATUS indicator for disconnected clients since they have to issue separate STATUS commands (or a LIST command if LIST-{EXTENDED,STATUS} have been advertized) to find out which mailboxes have got a new HIGHESTMODSEQ. Cheers, -- Guilhem.

NOTIFY regression: 2.18 no longer notifies of events in INBOX
by Guilhem Moulin 08 Sep '15

08 Sep '15

Here is an example with APPEND $ /usr/lib/dovecot/imap S1: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C1: a1 NOTIFY SET (INBOXES (MessageNew MessageExpunge FlagChange)) S1: a1 OK NOTIFY completed (0.000 secs) $ /usr/lib/dovecot/imap S2: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C2: a2 APPEND INBOX {1+} C2: x S2: a2 OK [APPENDUID 1384472528 26085] Append completed (0.229 secs). With 2.13 from Debian Jessie, S1 sends a notification for the new message in INBOX, as expected: S1: * STATUS INBOX (MESSAGES 4333 UIDNEXT 26086 UNSEEN 1) However it doesn't with 2.18 from Debian Sid, as if ‘INBOX’ was excluded from the mailbox filter ‘INBOXES’. It does send a notification for ‘virtual/unseen’ instead (as expected), but nothing for ‘INBOX’. S1: * STATUS virtual/unseen (MESSAGES 3 UIDNEXT 15186 UNSEEN 3) This is INBOX-specific because APPENDING the message to another mailbox triggers the notification on both 2.13 and 2.18 as expected: S1: * STATUS test (MESSAGES 2 UIDNEXT 3 UNSEEN 2) S1: * STATUS virtual/unseen (MESSAGES 2 UIDNEXT 15195 UNSEEN 2) I attach the ‘dovecot -n’ output for both 2.13 and 2.18. -- Guilhem.

question on autch cache parameters
by matthias lay 07 Sep '15

07 Sep '15

Hi list, I have a question on auth caching in 2.2.18. I am using acl_groups for a master user, appended in a static userdb file # snip ############################### master@uma:{SHA}XXXX=::::::userdb_acl_groups=umareadmaster allow_nets=127.0.0.1 # snap ############################### and use this group in a global ACL file. I discovered this only works on first NOT-cached login environment in imap-postlogin script on first login: AUTH_TOKEN=e96b5a32ceb2cafc4460c210ad2e92e3d7ab388c MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=ACL_GROUPS HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf ACL_GROUPS=umareadmaster IP=127.0.0.1 _=/usr/bin/env on the second cached login it looks like this AUTH_TOKEN=12703b11932f233520f6d4b33559c33aeb1cfc7f MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf IP=127.0.0.1 _=/usr/bin/env so the ACL_GROUPS is gone. is this intended to be like that. so groups not included in cache and I have to find another approach? anybody else encountered similar problems with some auth Variables and caching?

doveadm quota recalc problem for domain
by Samuel 06 Sep '15

06 Sep '15

Hello, I've set up user quota and domain quota for dict SQL and all seems OK. New mail for user increase the user quota and the domain quota. Deleting email count down user quota and domain quota. But in case of SQL failure, I'm trying to rebuild the user quota and domain quota with doveadm quota recalc. The problem is that the command : 'doveadm quota recalc -u foo@bar' sets the domain quota only with user foo@bar even when I try a domain quota recalc : doveadm quota recalc -A or doveadm quota recalc -u *@bar (only one user is taken in account for the domain quota and not all the user). The domain SQL database is broken with value of only one user for the whole domain quota. So how to achieve rebuild domain quota correctly with doveadm ? Thanks a lot. Samuel.

Considerations for a not so simple set-up ...
by Lars Hanke 05 Sep '15

05 Sep '15

I want to set up a new IMAP server with Dovecot, so far I've been running Cyrus. I'm running dovecot on Debian Jessie. The general idea of the system would be: 1) Virtual users, i.e. login users are disjoint from any mail accounts. 2) Real-Users authenticate using their kerberos tickets. 3) There is a n-to-n mapping of real to virtual users. 4) Maildirs shall be stored on glusterfs. 5) Fallback passwords for cloud access Concerning 1) and 2) I keep reading that this is possible, but I could not find any concise and current description. I'd welcome pointers to howtos. Concerning 3) this should be a matter of ACL, e.g. a single real user (kerberos pricipal) may have several mail-boxes (virtual users), and groups of real users may share the same mail-box. I have a faint idea, how this could be done in Cyrus (but never did that), but I read that these features should exist in Dovecot as well. But I'm completely lost to even figure out a starting point. I appreciate any keywords for further reading. Concerning 4) I read that there are some issues using NFS. Are there any caveats when using gluster? Concerning 5) Users logging in from outside may not have TGT on their notebooks, which by design should run as stand-alone. They should nevertheless be able to access their mail. I currently think of another set of real users, but anything less messy is welcome. Did someone try something similar, already? Thanks for your help, - lars.

'doveadm expunge' with -A and userdb { driver = passwd }
by Grant 05 Sep '15

05 Sep '15

I'm expunging mail in my crontab like this: doveadm search -u user1 mailbox INBOX.Trash savedbefore 30d doveadm search -u user2 mailbox INBOX.Trash savedbefore 30d doveadm search -u user3 mailbox INBOX.Trash savedbefore 30d ... I'd rather do this: doveadm search -A mailbox INBOX.Trash savedbefore 30d but I'm told not to: "If the -A option is present, the command will be performed for all users. Using this option in combination with system users from userdb { driver = passwd } is not recommended, because it contains also users with a lower UID than the one configured with the first_valid_uid setting." I'm using userdb { driver = passwd-file } but I'm guessing that's the same thing. Am I understanding this correctly? - Grant

Hi (New to dovecot) I am experiencing intermittent connection failures with both apple mail and ios mail. No specific errors and I cannot find relevant information on the mac logs or on my server. It spontaneously corrects. restarting dovecot - no dice It just happened now (again), this time there might have been a reason, I just dovecot-lda'd some large mailboxes from mbox to Maildir. But as I said, it spontaneously corrects, so is downloading now. While this connection error is occurring, then I can connect to dovecot via a remote mutt session, via web imap client and via outlook. Is this a known issue? FWIW: % doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.19.0-26-generic i686 Ubuntu 15.04 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes 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 } mailbox virtual/All { special_use = \All } prefix = } passdb { driver = pam } postmaster_address = postmaster(a)biovolt.nl protocols = " imap lmtp" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /tmp/dovecot-deliver.log log_path = /tmp/dovecot-deliver-errors.log } Thanks Eric

Reviving an old thread: "requiring client certificates for external connections"
by Robert Giles 03 Sep '15

03 Sep '15

Hi folks - reviving an old thread from 2010: http://www.dovecot.org/list/dovecot/2010-December/055837.html We're basically looking to do the same thing: require client certificates for external connections, while preserving certificate-less username/password authentication for internal connections. Any tips on the best way to accomplish this? 'ssl_verify_client_cert = yes' can go within a local {} block, but it doesn't seem to force the client to submit a certificate. Thanks in advance - Robert Giles

new server
by Franc 03 Sep '15

03 Sep '15

I am going to build a new box (2-3.000 users, 4-500 domains name (50-100 real, remaining used as redirect on the main (.it,.eu,.com,...)) . Is there any how-to or similar to follow for build an updated system? (My current boxes are based on CentoOS 6.x using included Dovecot + PostFix .rpms) I am thinking to CentOS 7.x + Dovecot + PostFix + RoundCube + Squirrel + procmail with unix users and virtual users. But I admit that systemd isn't still my best friend ... :-) In CentOS 7.x there is a default dovecot-2.2.10. Is it enough Ok or better use different rpms source? Any hints is welcomed :-) Thanks, F.

sieve filtering utf 8 strings
by Sergey Schwartz 03 Sep '15

03 Sep '15

Guys, I'm completely stuck, so asking for advice. My user has a sieve script which checks message header if it contains words in russian like 'Лист бронирования отправлен'. Pritty simple script # rule:[Отправлено] if allof (header :contains "subject" "LDS (robot): Лист бронирования отправлен", header :contains "from" "noreply(a)bgoperator.com") { fileinto "Отправлено"; } I don't have errors compiling the script or executing it via LMTP, but it doesn't work. Normally user receives messages from robot with subject encoded as quoted-printable Subject: =?UTF-8?Q?LDS_(robot):_=D0=9B=D0=B8=D1=81=D1=82?= =?UTF-8?Q?_=D0=B1=D1=80=D0=BE=D0=BD=D0=B8=D1=80=D0=BE=D0=B2=D0=B0=D0=BD?= =?UTF-8?Q?=D0=B8=D1=8F__=D0=BE=D1=82=D0=BF=D1=80=D0=B0=D0=B2=D0=BB=D0=B5?= When I send a test message via Thunderbird with required words - sieve works fine and subject is encoded in base64 Subject: =?UTF-8?B?0JvQuNGB0YIg0LHRgNC+0L3QuNGA0L7QstCw0L3QuNGPINC+0YLQv9GA?= =?UTF-8?B?0LDQstC70LXQvQ==?= It is the same text, but encodind is different - base 64 works fine and quoted-printable does not. Is it possible to have both supported for sieve ? -- Best regards, Sergey Schwartz Senior System Administrator Biblio Globus Tour Operator www.bgoperator.ru T: +7 495 5042500 ext 1532 E: sergey.schwartz(a)bgoperator.com

Hi, I'm using Dovecot 2.2.13-11 (Debian Jessie) and shared namespace (to be old Cyrus compatible setting): namespace { list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } My account: milo Other account: peter After subscription, I have: /vmail/user/milo/Maildir/Shared/peter/.INBOX/dovecot.index.pvt.log After unsubscribe, file and folder still exists. Where Dovecot stores the information, that I had unsubscribed from this folder? I need this to analyze subscriptions over all mail acounts. Thank you, Miloslav

Is there anyway of replicating between more than one other instance of Dovecot. I have bidirectional replication working successfully and it seems to be reliable. I would like to replicate from one or more of these instances to one other. Is this possible? Dirk

I put up a question on serverfault first, which has the details, including a stack trace: http://serverfault.com/questions/713687/dovecot-antispam-error-storing-mail . Details also copied below. Is this a known bug? If I built dovecot from source rather than using the Ubuntu 14.04 packages, would I expect that to help? Are there any configuration details that might be relevant?

doveadm-server hangs with 100% cpu usage
by Dennis Kuhn 02 Sep '15

02 Sep '15

we have some replication issues. From time to time a doveadm-server process takes 100% cpu in the state recv_mailbox_tree_deletes on the replica. The process runs forever until it is manually killed. Strace on this process doesn't show anything. Sometimes we have several doveadm-server processes in this state, all for the same account, all with 100% CPU Load. The logfile on the master says: Error: Timeout during state=recv_mailbox_tree Error: dsync(dobby5.heinlein-support.de): I/O has stalled, no activity for 600 seconds My workaround is to delete the user directory on the replica so that the whole account is replicated again. This solves the problem for this specific account. The dovecot version is 2.2.15 on the master and 2.2.16 on the replica.

Single Instance Storage after the fact
by Joe Beaubien 02 Sep '15

02 Sep '15

Hi everyone, I tried to find info about this online, but I couldn't find anything talking specifically about what I am trying to accomplish. I am sending and receiving the same attachments pretty often and as a result my email accounts are growing much more rapidly than I would like. *My goal* is to set up a second instance of Dovecot with SIS enabled and transfer everything over to this new Dovecot setup. I was thinking of simply running a dsync backup from the old instance and then a dsync backup -R on the new instance with SIS. Would this effectively create a new set of mailboxes without attachments (and a new folder full of attachments)? If not, can someone point me to information on how to accomplish this? Best regards, Joe B.

Post-migration questions
by Grant 29 Aug '15

29 Aug '15

I just migrated from courier-imap to dovecot and dovecot is a lot faster. My only client is webmail on the same server as dovecot. Max ~10 users. Should I still run imapproxy like I did with courier? Does dovecot periodically empty the trash folder like courier does? I reduced the number of processes courier was running to save RAM and improve performance. Are there any performance tweaks I should consider for dovecot? - Grant

IMAP hibernate feature committed
by Timo Sirainen 29 Aug '15

29 Aug '15

http://hg.dovecot.org/dovecot-2.2/rev/64c73e6bd397 Today I finally committed the "imap-hibernate" feature that I first started developing about a year ago (and had been thinking about for several years before that). The main purpose here is to reduce the number of imap processes and the amount of memory they use by moving IDLEing connections into imap-hibernate processes where they are waiting for something to happen (changes to the mailbox or IMAP client to do something). Mailbox changes are noticed only if inotify/kqueue is enabled, so without them the hibernation feature won't work well. For now only the IMAP connections that are in IDLE can be hibernated. In theory non-IDLEing connections could also be hibernated, but the main problem here is that if EXPUNGEs can't be sent at the time the hibernation is over, the current code can't handle it. They would require recreating a view that contains such expunged messages, which could be possible with some extra work. Some IMAP extensions aren't supported yet: - NOTIFY: This would just need to import/export the NOTIFY state. Also hibernation could be done at any time if VANISHED replies could be sent to the selected mailbox. - SEARCH=CONTEXT: A bit more troublesome extension to support. I'm not sure how big the trouble would be. It's rarely used though. - COMPRESS: The [de]compression code would need to be moved to login process instead of being done in imap-compress plugin. This would be a larger change, although it's also useful for various other purposes. The hibernation can be enabled for now simply by setting imap_hibernate_timeout setting to non-zero, which controls how long to wait after client has issued IDLE (and nothing happens) until the process hibernates. Some future work might include: - Moving the hibernation all the way to the first Dovecot proxy layer to avoid the need for imap-hibernate process at all. (Also moving the COMPRESS handling all the way there.) - Dynamically adjusting when the client should be hibernated instead of just a fixed imap_hibernate_timeout setting. Especially try to avoid such a situation where the hibernation is almost always terminated soon after it started. Although that probably is unlikely, so maybe not worth the trouble to prevent.. - Hibernation could be used to control the load of the server. If it's running too slow or if there are already too many imap processes, some of the connections could be moved to hibernation stage. Or just kept in hibernation for a while longer even after the imap process would normally be recreated (e.g. wait for several minutes before reporting new emails, or several seconds before replying to DONE). - The EXPUNGE/VANISHED and FETCH FLAGS replies aren't sent asynchronously, but instead fully buffered to the output buffer. This works as long as the list of changes after hibernation isn't huge, but otherwise it's wasting a lot of memory. - Maybe support non-inotify/kqueue change notifications from lib-storage. This could be complicated though to do efficiently. Or a simple way would be to just send a UDP or UNIX datagram packet on all changes to all the imap-hibernate processes and see if anybody cares about those. I'm not sure how efficient that would be.

28 Aug '15

Hello, I run a dovecot proxy (which is doing authentification itself) and a dovecot backend on separate boxes. I want to change the actual password scheme. Since postlogin scripting is not supported by proxies and %w variable is not forwaded to dovecot backend is there any way that I can update the password scheme with my current setup ? Thanks in advance.

Allow delivery to existing accounts only with LDAP and static
by Miloslav Hůla 28 Aug '15

28 Aug '15

Hi, we are using LDAP binding as a passdb, and static with allow_all_users=yes as an userdb. Works fine, but problem is, Maildirs are created for non-existent accounts too. We would like to prevent it. The LDAP binding does not supporta user lookups. Is the correct way to use checkpassword as a passdb before LDAP, check for account existency here and: result_success=continue result_failure=return-fail ? Thank you, regards, Miloslav

Long version: I've been using dovecot/postfix for a 12 user environment for several years, and today was the first time I ran into an issue I could not solve from reading the documentation. The server is gentoo running on esxi. A few times a year I've made a snapshot of the server and copied the files to my home esxi server as a full system backup. 5 days ago the internet connection at the office broke, and I decided to power on the last copy of the server at my home and change public dns so that users could access their new mails via webmail from this spare server. (I didn't allow imap through firewall.) Now the network at the office is back. DNS is updated so that mails are delivered to the office server again. But all the mails sent / received during those 5 days is only at my house. How can I merge those into the office server?I'd like to do this as a server administrator. I do not want to have each user forward the mails to them self from the temporarily webmail. I tried to just copy the mail files on my own account - like I did once when I used courier-imap, but that did not work with dovecot. I hope someone has an idea of how to solve this.

Hello, I'm using the Debian builds of dovecot-2.2 by S[r]us.

mailbox deletion is not replicated correctly
by Dennis Kuhn 27 Aug '15

27 Aug '15

i can't delete several folders at once. I have a folder structure like folder1/folder2/folder3 (we use slash as hierarchy separator). When i delete folder1 server1 executes the command correctly Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2/folder3 Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2 Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1 but the replica server2 reverses the order: Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1 Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2 Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2/folder3 This creates the folder INBOX/Trash/folder1/folder2 on server2 again which replicates back to server1.

mail_log proposal: recipient
by Peter Chiochetti 27 Aug '15

27 Aug '15

As Timo seems to be on a committing spree; I'd like to propose that in the mail_log_fields the recipient would be available. Like probably many dovecot users, my MUAs save to Sent; so when grepping the log to learn etc. that would just be useful Kind regards -- peter

Duplicate folder names
by Paulo Matos 26 Aug '15

26 Aug '15

Hi, I have setup message filtering and for example, I might move a message which a given sender to folder special/. This folder is created and shows up twice in INBOX/special/ and special/. They are however exactly the same folder. If I subscribe to one I am automatically subscribed to the other and viceversa. Not too happy with this configuration. I have a feeling this is related to namespaces but I am not sure in which way to configure things in order to have only INBOX/special but not special/. How can I set this up. My current configuration is: $ dovecot -n # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.1.0-x86_64-linode59 x86_64 Fedora release 22 (Twenty Two) ext4 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes auth_verbose_passwords = yes default_internal_user = root imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir maildir_very_dirty_syncs = yes mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace inbox { 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 } postmaster_address = pmatos protocols = imap quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = $default_internal_user } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ log_path = /home/vmail/dovecot-deliver.log } protocol imap { mail_max_userip_connections = 100 } Regards, Paulo Matos

Hello folks, Any plans on implementing the PROXY protocol to allow Dovecot being behind a TCP proxy, and still logging the real IP address of the users ? See : http://blog.haproxy.com/haproxy/proxy-protocol/ Thanks !

Shared Mailboxes Not Visible

OK, gurus, I've spent the last 2 days crawling through all of the posts and web postings regarding shared folders, and I simply cannot get it to work.

sieve and managesieve are both working fine, have been for years. Now I want to add a sieve_after script: /etc/dovecot/conf.d/90-sieve.conf : plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = sieve_after = ~/sieve/personal.sieve sieve_subaddress_sep = + } I have compiled ~/sieve/personal.sieve to ~/sieve/personal.svbin, but it doesn't seem to be read. Any hints? thanks Per Jessen -- Per Jessen, Zürich (17.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.

Store ACL files within shared mailbox / rename shared folder problem
by Chris Laif 24 Aug '15

24 Aug '15

Hi. If $otheruser shares a mailbox to $myuser, my private index is stored in *my* Maildir, according to this template (from the dovecot docs): mail_location = maildir:%%h/Maildir:INDEXPVT=%h/Maildir/shared/%%u If $otheruser renames the shared mailbox, all my private mail flags (Seen) are lost because my mailclient couldn't find the private index anymore. Is there any way to store the private index within the shared mailbox? If $otheruser renames the mailbox, the index will be 'migrated' as well. Something like this: /data/mails/$otheruser/Maildir/.MagicSharedFolder/shared/$myuser.dovecot.index.pvt.log I see no way on how to do craft a INDEXPVT for this. Kind regards, Chris

plugin antispam sa-learn run program failed with exit code -1
by Guillaume Lakano - DOVECOT 24 Aug '15

Hello ! I've installed iRedMail on an Ubuntu Server 14.04.1 I'm not the only one on the iRedMail forum to have the problem, but the developpers of iRedMail doesn't found the problem and advice me to ask you directly. When I want to move an email directly to /Junk/ this not works. In Thunderbird, the error is : "[SERVERBUG] failed to send mail" In RoundCube, the error is : "Server Error: UID MOVE: failed to send mail ." But, if we firstly delete the email, then move the email from /Trash/ to /Junk/ this works.
