Question wrt. dovecot replicator
by Remko Lodder 30 Oct '14

30 Oct '14

Hi People, I recently setup a replication service within dovecot between two machines in different datacenters, which has the following configuration; (yes it is hashed out, because I needed to) #service replicator { # unix_listener replicator-doveadm { # mode = 0666 # } # process_min_avail = 1 #} # #service aggregator { # fifo_listener replication-notify-fifo { # mode = 0666 # #user = vmail # } # unix_listener replication-notify { # mode = 0666 # #user = vmail # } #} # #service doveadm { # inet_listener { # port = 12346 # } #} # ##doveadm_port = 12346 #doveadm_password = XXXXXXX #replication_max_conns = 30 # and a mail_replica = tcp:host{a,b}:12346 configuration on each host so that they are pointing to eachother; This seems to work fine for most accounts, for example: I never experienced issues with this. However, several other accounts (with a large variety of clients) got duplicated emails. Looking with doveadm I only noticed that the numbers of the messages are closely related to eachother but one number incremented. So they cannot be deleted with the deduplicator function. The replication is provided over TCP only, the connection streams over an OpenVPN tunnel so that the contents are protected, the machines are located in different Datacenters but close to eachother. How can I determine why there are duplicated emails? What kind of messages should I specifically look for? Can I set this up for a few selected accounts instead of all accounts like it was currently? To make sure I do not make things worse for others then needs to be :-) The service had been disabled for the time being to prevent the other users from getting duplicated emails. Thanks for the advice in advance!

different mail location in different namespace
by Héctor Moreno Blanco 30 Oct '14

30 Oct '14

Hello everyone, We have Dovecot 2.1.6. With different Namespaces: ... mail_location = maildir:%h/Maildir ... namespace { separator = . prefix = inbox = yes type = private } namespace { inbox = no location = prefix = INBOX. separator = . hidden = yes type = private list = no } namespace { location = maildir:/buzon/archivo/%u/_ARCHIVO prefix = _ARCHIVO. hidden = yes separator = . type = private } We take the attribute "home directory" from the LDAP in the userdb attributes. We would like to modify this attribute for the Namespace ARCHIVO. For example, if a home directory is /buzon/buzon1/11111111, the mail location for ARCHIVO would be /buzon/archivo1/11111111. Is this modification possible without adding another attribute at the LDAP (just editing the attribute)? Thank you very much in advanced. Kind regards. Héctor Moreno.

Bug in the combination of Lazy_expunge and acl plugin
by Philipp Faeustlin 30 Oct '14

30 Oct '14

Hello Timo, Hello Dovecot Developers, Hello everyone on the list, I think I have some bug, because I haven't found a working configuration till now. I use latest dovecot 2.2.13 from the dovecot-ee repository, with acl and the lazy_expunge plugin. My configuration for shared folders work fine with lazy_expunge disabled. If I enable lazy_expunge and the user (named userA), which I'm testing with, got no shared folders, then lazy_expunge is working as supposed. Now I add some shared folder for example per doveadm: doveadm acl set -u userB(a)domain.de INBOX user=userA(a)domain.de lookup read write write-seen write-deleted insert expunge create After that every list command fails with: Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' '.EXPUNGED/' is the name for the namespace of lazy_expunge. Easiest way for me to reproduce the error is: doveadm mailbox list -u userA(a)domain.de which results in: ----------------- Trash Drafts Sent doveadm(userA(a)domian.de): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' ------------------ I hope someone can confirm this behavior and or give me some hints to get rid of it. Regards Philipp Fäustlin

Bug in fts (solr?, Maildir?) incorrect last_indexed_uid
by Karl O. Pinc 30 Oct '14

30 Oct '14

Hi, I thought I should document this. (Dovecot 2.2.9, see config at bottom.) I installed dovecot and then converted a number of mbox mailboxes to Maildir, and had a number of pre-existing Maildir mailboxes. I then installed the debian (wheezy) fts-solar and jetty packages, and tested my inbox using the "telnet localhost imap ... 3 SEARCH text "test" method as described on the dovecot wiki. Everything seemed to work. But when I used balsa to search a mailbox other than my inbox, I got no results. "doveadm dump" on the searched mailbox showed that "last_indexed_uid" to be the last uid of my inbox. Stopping dovecot, deleting out the dovecot-index* files, starting dovecot, and re-running "doveadm dump" showed a non-existant last_indexed_uid -- that is, last_indexed_uid did not show up in the dump output. Using the telnet method above to attempt to search again yielded no results, but this time (I think, I also tried various times with balsa) the last_indexed_uid value was that of the last uid in my trash mailbox. I don't believe I'd yet tried fts on my trash. Using balsa as an imap client the results were very consistent; every Maildir where "doveadm dump" returned no last_indexed_uid value had the last_indexed_uid set to that of the inbox's largest uid. Running "doveadm fts rescan -u foo" fixed the problem. (FWIW, now all the Maildirs seem to have a last_indexed_uid=0.)

Quota reporting
by Hanns Mattes 30 Oct '14

30 Oct '14

Hi, my main server will be upgraded from Dovecot 1.2something to 2.2. For testing I've installed a setup with postfix, handing malis as a relay via lmtp. So far it's up and running - really nice. AFAICS there's one issue left: Thunderbird and Kmail don't show the quota status. Using doveadm quota the information is shown correctly, even the user-specific values (coming from openldap) are set correctly. I think, I miss something obvious ...

Renaming not supported across conflicting directory - why?
by Arkadiusz Miśkiewicz 30 Oct '14

30 Oct '14

I wonder what is point of checkign file/dir create mode like this? Here it makes problems since some folders have different permissions than others but both are accessible/writable by user. So renaming is possible (as renaming according to unix permissions). Yet dovecot artificially prevents this. /* if we're renaming under another mailbox, require its permissions to be same as ours. */ if (strchr(newname, mailbox_list_get_hierarchy_sep(newlist)) != NULL) { struct mailbox_permissions old_perm, new_perm; mailbox_list_get_permissions(oldlist, oldname, &old_perm); mailbox_list_get_permissions(newlist, newname, &new_perm); if ((new_perm.file_create_mode != old_perm.file_create_mode || new_perm.dir_create_mode != old_perm.dir_create_mode || new_perm.file_create_gid != old_perm.file_create_gid)) { mailbox_list_set_error(oldlist, MAIL_ERROR_NOTPOSSIBLE, "Renaming not supported across conflicting " "directory permissions"); return -1; } } -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Sieve plus addressed mail filtering
by Peter Chiochetti 30 Oct '14

30 Oct '14

Today I learned, that to filter incoming plus addressed mail (user+tag@…) I had to deviate from the documentation. There it reads: if envelope :detail "to" "spam"{ fileinto "Spam"; } Instead I had to write: if address :is :detail "To" "tag"{ fileinto "Tagged"; } Dovecot version is 2.2.13-1+bigmichi1~precise+1 -- peter

Released Pigeonhole v0.4.4 for Dovecot v2.2.15.
by Stephan Bosch 30 Oct '14

30 Oct '14

Hello Dovecot users, It's been about 5 months since the last Pigeonhole release, so it is high time for a new one. However, the main reason to make a release now is the fact that Dovecot v2.2.15 has one change that causes problems with the previous release of Pigeonhole. Unlike recent earlier releases, this release has a few big new features. Most notably, I implemented a generic Sieve script storage framework. This means that it is now relatively easy to implement a storage driver to retrieve Sieve scripts from a location other than the file system. An important effect of this new implementation is that these alternative storage locations can also be used with sieve_before/sieve_after. Also, storing Sieve scripts there using ManageSieve is also possible, provided that the driver provides an implementation. I used the new framework to implement an LDAP storage driver. However, it is read-only, which means that it doesn't currently provide ManageSieve support. Several bugs were fixed. The most nasty ones were related to the doveadm-sieve plugin (which is one of the reasons why this release took so long). The new script storage driver framework entailed large changes in this plugin, so many of these problems were addressed implicitly. Hopefully, all problems are solved now. Changelog v0.4.4: * Added support for Japanese mail addresses with dots at non-standard places in localpart. * Changed handling of ENOSPACE into a normal temporary failure and added handling of ENOQUOTA as a user error. * Restructured result execution, so that all actions which involve mail storage are always committed before all others. + Implemented support for generic Sieve storages. Using alternative storages now also possible for sieve_before/sieve_after. + Implemented storage driver for retrieving Sieve scripts from LDAP. This currently cannot be used with ManageSieve. + Implemented sieve_redirect_envelope_from setting, which allows configuring the envelope sender of redirected messages. - Fixed handling of mail storage errors occurring while evaluating the input message. - managesieve-login: - Removed bogus ALERT response code returned for AUTHENTICATE command. - Fixed handling of invalid initial response argument to AUTHENTICATE command. - Fixed handling of stream errors in lexical scanner. - Fixed handling of SMTP errors. Permanent and temporary errors were mixed up. - Fixed several problems reported by CLang 3.4. - duplicate extension: Fixed erroneous compile error about conflicting tags when `:handle' argument was used last. - relational extension: Fixed error handling of `:value' match. - editheader extension: Fixed header unfolding and header iteration. - mailbox extension: Fixed the `:create' tag, which erroneously subscribed an existing folder. - extprograms plugin: Fixed handling of error codes. - doveadm-sieve plugin: Fixed several bugs. Synchronization of symbolic link in the file storage should now also work properly. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.4.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.4.tar… 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

v2.2.15 released
by Timo Sirainen 30 Oct '14

30 Oct '14

http://dovecot.org/releases/2.2/dovecot-2.2.15.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.15.tar.gz.sig Some small fixes and changes to v2.2.14. This release is mainly in the hope that it could still make it into the next Debian stable instead of v2.2.14 - mainly because of a couple of new assert crashes that started happening in v2.2.14 and should be fixed now. * Plugins can now print a banner comment in doveconf output (typically the plugin version) * Replication plugin now triggers low (instead of high) priority for mail copying operations. * IMAP/POP3/ManageSieve proxy: If destination server can't be connected to, retry connecting once per second up to the value of proxy_timeout. This allows quick restarts/upgrades on the backend server without returning login failures. * Internal passdb lookups (e.g. done by lmtp/doveadm proxy) wasn't returning failure in some situations where it should have (e.g. allow_nets mismatch) * LMTP uses mail_log_prefix now for logging mail deliveries instead of a hardcoded prefix. The non-delivery log prefix is still hardcoded though. + passdb allow_nets=local matches lookups that don't contain an IP address (internally done by Dovecot services) + Various debug logging and error logging improvements - Various race condition fixes to LAYOUT=index - v2.2.14 virtual plugin crashed in some situations

smtp lastlogin
by Eduardo Ramos 30 Oct '14

30 Oct '14

Hey guys! I've been googling without success. Do anyone know if there is a way to track last login of a smtp authentication? I've tried without success using: service auth { executable = auth lastlogin unix_listener auth-userdb { } unix_listener /var/spool/postfix/private/auth { mode = 0660 group = postfix } } service lastlogin { executable = script-login -d /usr/local/bin/lastlogin.sh unix_listener lastlogin { user = $default_internal_user mode = 0666 } }

[Pigeonhole] Problem compiling latest snapshot

29 Oct '14

Hi, http://hg.rename-it.nl/dovecot-2.2-pigeonhole/rev/a1e57385b267 added the use of update-version.sh, but this file and is-tagged.py are not included in Pigeonhole, only in Dovecot sourcecode. Therefore pigeonhole- version.h is not generated during compilation leading to a compile error: ../../../../src/lib-sieve/sieve-config.h:8:32: fatal error: pigeonhole- version.h: No such file or directory #include "pigeonhole-version.h" Regards, Bernd

Pigeonhole 0.4.4 error with no sieve rules
by James 29 Oct '14

29 Oct '14

I have built and installed Pigeonhole 0.4.4 with Dovecot 2.2.15. For users with no sieve at all I am getting an error on delivery. Delivery is from exim via lmtp. Syslog: Oct 28 11:03:50 mailhost dovecot: [ID 583609 mail.crit] lmtp(18915): Fatal: master: service(lmtp): child 18915 killed with signal 11 (core not dumped - set service lmtp { drop_priv_before_exec=yes }) There is no global sieve script because there is no global sieve rule. Where an account has sieve rules delivery works as expected. To make it work again I've gone back to 2.2.15 with 0.4.3. James.

Dovecot 2.2.14 and per user \Seen flags
by Thomas Robers 29 Oct '14

29 Oct '14

Hello, I have a Dovecot Installation Version 2.2.14 on CentOS 6.5 with shared folder. UserA shares his INBOX to user UserB. I activated "per user \Seen flags" with location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared I think the INDEXPVT setting activates this setting, right? I activated this setting when there were already several accounts in use. Before we used shared \Seen flags. But this setting doesn't work on my system. For example UserB marks several Messages as read in a shared INBOX from UserA and erverything seems alright but then suddenly all seen Messages are marked as unread again and I see the following error message in the log file: Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Error: /export/home/imap/UserB(a)tutech.de /shared/.INBOX/dovecot.index.pvt reset, view is now inconsistent Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Disconnected: BUG: Unknown internal error in=1020 out=2757 My Dovecot configuration is: root@mail:~# doveconf -n # 2.2.14: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/export/home/imap/%Lu/Maildir mail_plugins = acl zlib 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 duplicate mbox_write_locks = fcntl namespace { hidden = no ignore_on_failure = no inbox = no list = children location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes list = 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 = INBOX/ separator = / type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/export/home/shared-db/shared-mailboxes mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size zlib_save = gz zlib_save_level = 6 } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 process_min_avail = 20 } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } } ssl = required ssl_cert = </etc/pki/dovecot/certs/mail.tutech.de.crt_chain ssl_key = </etc/pki/dovecot/private/mail.tutech.de.key ssl_protocols = !SSLv3 !SSLv2 syslog_facility = local6 userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = acl zlib sieve } protocol imap { mail_plugins = acl zlib imap_zlib imap_acl } I don't know, is there something wrong with my configuration, am I missing sonething?

maildir++ quota support on dovecot
by Mirko ML 28 Oct '14

28 Oct '14

Some information about maildir++ that I have read: http://www.inter7.com/courierimap/README.maildirquota.html http://wiki2.dovecot.org/Quota/Maildir When I have to deliver a message with an MDA I can use dovecot-lda. If I have enabled "quota = maildir:User quota" I am pretty sure that in the mailbox on file system I find a file named "maildirsize" maildirsize on top contain something like this "xxxxxxxxxxS" that specifies the SIZE quota in bytes. LDA could delivery the message only when the SIZE written in mailbox is less than the SIZE defined by mail admin. "Each member of the list consists of an integer followed by a letter, specifying the nature of the quota. Currently defined quota types are 'S' - total size of all messages, and 'C' - the maximum count of messages in the maildir. For example, 10000000S,1000C specifies a quota of 10,000,000 bytes or 1,000 messages, whichever comes first." For this reason the value in bytes defined for the user must have S at the end. At the moment quota-maildir.c contains a control for S or C so I can find this in log: Quota rule: root=User quota mailbox=* bytes=20971520 messages=0 But quota-util.c do not contains a control for C and S, so probably the support of maildir++ format is not complete. Please let me know if I am wrong. -- Ciao Mirko

Namespaces (or another way) to put messages in a different drive
by Paulino Michelazzo 28 Oct '14

28 Oct '14

Hello people, I have a situation where I need to create a mailbox for clients where they put old messages (> 1year) but I would like to create this mailbox in a different disk. I have a server with the mailboxes and a storage mapped using NFS just to create those mailboxes for old messages. I was trying to namespaces but every time that I make the configurations, the authentication system stop and the clients can’t log in. I really don’t know if this is the best approach for my situation (mailbox with old emails in a storage) and, if namespaces can solve it. The infos that I have are: Dovecot version 2.1.7 mailboxes: Namespace configs: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = private separator / prefix = storage/ location = /mnt/exibstor/%u inbox = no hidden = no list = yes } If someone knows how can I do that, I really appreciate it. Best regards, Paulino Michelazzo

Sieve: carry global variables from sieve_before to user sieve scripts
by Alexander 'Leo' Bergolth 26 Oct '14

Hi! Is there a way to initialize global variables with default values in sieve_before scripts that can be used in the sieve_default script or in user scripts? I've tried the following code but this doesn't work.. before.d/10-set-defaults.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; set "global.S_TESTVAR leo"; debug_log "LEO SIEVE: in before.d/10-set-defaults, S_TESTVAR: ${global.S_TESTVAR}"; -------------------- 8< -------------------- default.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; global "S_TESTVAR"; debug_log "LEO SIEVE: in default.sieve: S_TESTVAR: ${global.S_TESTVAR}, ${S_TESTVAR}"; -------------------- 8< -------------------- Is there any other way to set up defaults in a global sieve script?

imap-postlogin and doveadm

We are configuring location= running a bash-script during imap-postlogin setting $MAIL in $USERDB_KEYS, as described in wiki/PostLoginScripting.txt This works fine. However, running a command like 'dovadm index [-u user] folder' only works for users with settings that match the default in mail_location= Would it be possible to make the location available for doveadm in a similar way, either with command line arguments or in the enviroment? hmk

Dynamic tags in email address
by Felix Gustavsson 25 Oct '14

25 Oct '14

I'm trying to get dynamic tagging (user+sometag(a)example.com) to work on a mail server I'm setting up, however it only works as long as it's sent to the main user and not to aliases. virtual-alias-maps query: SELECT get_email_alias_dyn('%s') virtual-mailbox-domains query: SELECT 1 FROM domain WHERE name='%s' virtual-mailbox-maps query: SELECT 1 FROM user_alias INNER JOIN domain ON user_alias.domainID = domain.id WHERE user_alias.primary = 1 AND CONCAT(user_alias.name, '@', domain.name)='%s' "get_email_alias_dyn()" is a stored function which returns the destination email, so alias+tag(a)example.com returns user(a)example.com, alias(a)example.com returns user(a)example.com and so on. It works perfectly fine when the mail does not contain any tags (alias(a)example.com or user(a)example.com) or if it's the primary email which contains tags (user+sometag(a)example.com) but when it's tags on an alias the mail is bounced due to "user unknown". I tried modifying the dovecot service in master.cf so the addresses can be filtered with Sieve (http://wiki2.dovecot.org/LDA/Postfix) but that did not solve the issue either, so I have not idea where it goes wrong or how to solve it. I have included the logs from when I sent to alias+tag(a)example.com below: Oct 25 19:54:20 xx postfix/smtpd[10987]: connect from mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:21 xx postfix/smtpd[10987]: 10585DFA63: client=mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:21 xx postfix/cleanup[10995]: 10585DFA63: message-id=<CAGPeO-YcJwbRJb-Gfga+G_vKqj9cm80rMZf9LAfENRCFfxLVAg(a)mail.gmail.com> Oct 25 19:54:25 xx postfix/qmgr[9945]: 10585DFA63: from=<xx(a)gmail.com>, size=1743, nrcpt=1 (queue active) Oct 25 19:54:25 xx postfix/smtpd[10987]: disconnect from mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:25 xx dovecot: auth-worker(11000): mysql(127.0.0.1): Connected to database mailcp Oct 25 19:54:25 xx postfix/pipe[10998]: 10585DFA63: to=<xx+test(a)xx.com>, relay=dovecot, delay=5.4, delays=5.4/0/0/0.03, dsn=5.1.1, status=bounced (user unknown) Oct 25 19:54:25 xx postfix/cleanup[10995]: D39B2DFC7D: message-id=<20141025175425.D39B2DFC7D(a)xx.com> Oct 25 19:54:25 xx postfix/bounce[11002]: 10585DFA63: sender non-delivery notification: D39B2DFC7D Oct 25 19:54:25 xx postfix/qmgr[9945]: D39B2DFC7D: from=<>, size=3937, nrcpt=1 (queue active) Oct 25 19:54:25 xx postfix/qmgr[9945]: 10585DFA63: removed Oct 25 19:54:26 xx postfix/smtp[11004]: D39B2DFC7D: to=<xx(a)gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.195.27]:25, delay=0.24, delays=0/0/0.16/0.07, dsn=2.0.0, status=sent (250 2.0.0 OK 1414259666 d8si5463492wiv.41 - gsmtp) Oct 25 19:54:26 xx postfix/qmgr[9945]: D39B2DFC7D: removed The dovecot-sql.conf.ext file looks like this: driver = mysql connect = host=127.0.0.1 dbname=mailcp user=mailcp password=xxx default_pass_scheme = SHA512-CRYPT password_query = SELECT CONCAT(user_alias.name, '@', domain.name) as user, user.password as password, concat('*:bytes=', (CASE WHEN user.quota -1 THEN user.quota ELSE domain.quota END)*1000000) AS userdb_quota_rule FROM user INNER JOIN user_alias ON user.id = user_alias.userID AND user_alias.primary = 1 INNER JOIN domain ON user_alias.domainID = domain.id WHERE CONCAT(user_alias.name, '@', domain.name) ='%u' AND user.status = 1 user_query = SELECT CONCAT('/var/mail/vmail/', domain.name, '/', user_alias.name) as home, 5000 AS uid, 5000 AS gid, concat('*:bytes=', (CASE WHEN user.quota != -1 THEN user.quota ELSE domain.quota END)*1000000) AS userdb_quota_rule FROM user INNER JOIN user_alias ON user.id = user_alias.userID AND user_alias.primary = 1 INNER JOIN domain ON user_alias.domainID = domain.id WHERE CONCAT(user_alias.name, '@', domain.name) ='%u' AND user.status = 1

Sieve duplicate detection
by Bruce Bodger 25 Oct '14

25 Oct '14

Good day, Gents. We are running: dovecot 1.2.17 dovecot-1.2-sieve-0.1.19 dovecot-1.2-managesieve-0.11.13 postfix 2.4.3 on OS X 10.5.8 server. Only about 15 users access the server. No problems. My question is... what would I have to upgrade, and to what version, in order to take advantage of pigeonhole sieve's duplicate detection (vnd.dovecot.duplicate) functionality? Thank you very much.

Invoking the spam checker on the sieve script
by Alejandro Exojo 25 Oct '14

25 Oct '14

Hi. TL/DR version: Is it advisable to invoke an spam checker from the sieve script, and then, once the message is filtered, decide if should be moved to a certain spam folder? A bit more context on why I'm considering this: I'm just a geek who wants to handle his own mail, but not a great experience as a system administrator. I don't have any corporate setup, just a simple VPS with me as the only user. Previously I fetched all my mail through POP, and in the client of my PC I moved (lots of) mailing list traffic to its folders. Then, for those remaining messages (and only those remaining) I passed the spam filter and moved to spam folder. That's a significant saving since I have many mailing list subscriptions, and now I'm even using rss2email, so I have lots of email that is not spam. I moved to IMAP and my filters are server side with sieve, but I don't have spam filtering yet. I thought I could replicate the setup easily, but it seems nobody is doing that, and everyone has the mail already scored when it reaches sieve. Seems like the "extprograms" extension would be a fit, but again, nobody seems to mention on documentation, so I'm fearing I'm probably wrong. Suggestions? Thank you very much! -- Alex (a.k.a. suy) | GPG ID 0x0B8B0BC2 http://barnacity.net/ | http://disperso.net

I searched for them and haven't come across them yet. Could any point me in the right direction? Specifically the Ubuntu 12.04 package notes if they're split out. Thanks!

Properly "locking" a useraccount (on a proxy)
by Ralf Hildebrandt 25 Oct '14

25 Oct '14

I'm preparing a migration of several mailboxes to another machine. The different useraccounts are distributed to different backend machines by means of a dovecot LMTP/IMAP/POP proxy. Proxying is working really well (now that the kernel does as it should). But how can I "lock" a user during migration? The plan is: ============ * lock the user * kick the user (doveadm kick) * migrate mailbox (some rsync magic) * unlock the user again But how would I lock the user? What locking needs to achieve: 1) Disallow IMAP/POP login (that's easy!) 2) defer LMTP delivery somehow (Postfix is talking to dovecot's LMTP server) Because currently, we're seeing dovecot trying local delivery on the proxy machine once an account is locked (probably because LMTP proxying uses passdb lookups, and since that one is failing it's using the userdb lookup?): Oct 21 20:15:27 lmtp(87892): Error: user sys4(a)test.invalid: Initialization failed: Namespace '': mkdir(/var/mail/test.invalid/sys4/mdbox/mailboxes) failed: Permission denied (euid=10000(vmail) egid=10000(vmail) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0775) Admittedly, this is somehow working. But it's not very elegant to use a side-effect. Is the a reserved userdb/passwd return value which will let dovecot "tempfail" in a n elegant fashion? -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Dovecot Master/Master Replication Problem
by Felix Amler 25 Oct '14

25 Oct '14

Hi, I've set up 2 servers with dovecot 2.2.9 using maildir using structure: /var/maildir/domain/localpart Server A: mx1.xxx.de Server B: mx2.xxx.de Mails are delivered to dovecot only on server A by exim4/dovecot deliver replication to Server B works immediatelly: mark mail as read on server A, mail is marked as read on server B. BUT: when i mark a mail as read on Server B, noting happens. On Server A I get messages like this in dovecot-error.log: 2014-10-22 22:35:05 dsync-server(localpart(a)domain.de): Error: stat(/var/maildir/domain.de/localpart/.dovecot-sync.lock/tmp) failed: Not a directory 2014-10-22 22:35:05 dsync-server(localpart(a)domain.de): Error: Failed to access mailbox dovecot-sync.lock: Internal error occurred. Refer to server log for more information. [2014-10-22 22:35:05] I googled a bit, this could habben if there is a file ".dovecot-sync.lock" in the maildir, but I've double checked that, there is no such file... Why does it work in one direction, but not in the other? Please help best regards Felix

Replication .dovecot-sync.lock
by Hans-Werner Paulsen 25 Oct '14

25 Oct '14

Hello all, I have set up two servers with dovecot and replication. The mail location is mail_location = sdbox:/var/spool/mail/%u Everything works fine when I override the homedirectories userdb { driver = passwd override_fields = home=/var/spool/mail/%u } But, when I do not override the homedirectories, replication does not work, and the following error is logged: Oct 24 14:40:45 dsync-local(hans): Error: Couldn't create lock /afs/mpa/home/hans/.dovecot-sync.lock: Permission denied With a self-written module an IMAP user can get access to his homedirectory: protocol imap { mail_plugins = afsToken } The user has to type in his password. Obviously this does not work for replication. Is there a way to specify a different location for the lockfile? Isn't better to use the maildirectory but the homedirectory? Is there a way to set the homedirectory differently for replication? Thank you for any help.

Replication only sporadic
by Lucas Rothamel - Eye Catching Webdesign 24 Oct '14

24 Oct '14

Hello dear Dovecot Gurus, I am setting up two servers with Dovecot replication as hot-standby servers for a small high availability cluster, switch-over through DNS-redirect. For testing purposes, both servers are generating a small test mail every few minutes and delivering to the local dovecot each. In my mail client, I added both servers through IMAP to watch how the replication is working. However, I noted that replication is very sporadic: sometimes a new email is received "instantaneous" by both servers, then no replication updates are visible for hours, and suddenly all missing mail appear in the other server. Why is this? Can this be changed to be more realtime? Thank you!

Sieve Advice Needed, Please
by Casey Bralla 24 Oct '14

24 Oct '14

Anybody here familiar with the Sieve language? I'm rebuilding my mail server, and I am working with the sieve language to automatically filter spam into a separate account. However, I've hit a snag that I can't get around. BTW, I'm using a clean install of dovecot, postfix, spamassassin on Debian 7.5. I want to do server-side spam filtering, so I've got spamasassin identifying spam, and then have sieve sorting the mail to a special spam folder. I can easily send spam to special folder in the inbox for each mail user, but I wanted to have a single mail account for spam. I can use the "redirect" sieve command to send anything with the X-spam-flag set, but this triggers an error and bounces the offending mail. The bounce message is: From: MAILER-DAEMON(a)NerdWorld.org (Mail Delivery System) To: casey(a)vmailservertest.nerdworld.org Subject: Undelivered Mail Returned to Sender Date: Sun, 19 Oct 2014 16:41:49 -0400 (EDT) This is the mail system at host VMailServerTest.NerdWorld.org. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.

I tried to get clever and prevent the recursion, but I'm not clever enough. Here is my sieve rule file. # # # A rule to move spam to the spam user # based on spamassassin setting the spam flag # # # require ["redirect"]; (Not needed, since it is part of the basis sieve spec) # # rule:[SPAM] if header :contains "X-Spam-Flag" ["YES"] { if address :is "to" "Spam(a)VMailServerTest.NerdWorld.org" { keep; } else { redirect "spam(a)VMailServerTest.NerdWorld.org"; } } # # # Anybody able to give me any advice?

Been there, done that (for a different problem). Not all mail readers will show you banners; to make this really work, you have to implement USER and PASS (accepts anything), STAT and LIST (one message available), RETR (dump your informational message payload), QUIT (disconnect), maybe TOP, and everything else is an +OK no-op.

Hello, I like to enable the allow_nets Feature (http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets) for my customers. To help them knowing there own IP I imagine a special mailbox/loginuser at the pop3 server. That user could give a valid pop3 answer from a dummy pop3 server or simply throw a login error with customised answer containing the IP information. Has anybody done something similar or ideas to build such a system? Thanks for ideas Andreas

What is the correct way to configure the mail_location option for Mailidr format?
by deoren 23 Oct '14

23 Oct '14

Short version: What is the correct way to configure the mail_location option for Mailidr format? I've long had it setup this way: mail_location = maildir:/var/vmail/%d/%n based on this guide: https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-my… Is that correct? Longer version: After upgrading from Dovecot v2.0.x to v2.2.x yesterday I'm coming to the conclusion that I've got it configured wrong. This is probably compounded by my bright idea of explicitly setting the path separator prior to the upgrade like so: separator = . Because we're using Maildir I thought it would be useful to explicitly set the separator value to what the default is for Maildir. I figured this would be a good way to remind myself what the separator is by default. I also figured while I was merging the conf changes between v2.0 and v2.2 I could roll that additional change in also. Looks like that was a bad idea to include unnecessary changes until things had stabilized. I should know better; I was too optimistic for my own good. Here is an example error message I ran into: stat(/var/vmail/example.com/username/.dovecot.lda-dupes/tmp) failed: Not a directory which is nearly identical (other than leading path) to what is shown here: http://www.dovecot.org/list/dovecot/2010-April/048227.html Steffen Kaiser responded with, "You should not (must not) have home == maildir root." That is when I double-checked the guide that I mentioned above and found that I had followed their directions exactly for that conf setting. Looking at some other guides/tutorials shows something more like: mail_location = maildir:/var/vmail/%d/%n/Maildir I assume the latter is how it's supposed to be done? If so, that would explain the problems I've had with Sieve scripts in the past until I explicitly set 'sieve_dir' like so: sieve_dir = /var/vmail/sieve/%d/%n/sieve_dir I did review the official docs here: http://wiki2.dovecot.org/MailLocation/Maildir but I didn't find where it explicitly warns against setting home == maildir root. It should probably be apparent, but it wasn't to me when I first configured that setting. Thanks in advance for your help. If it turns out that the linode.com guide is wrong I'll create a Pull request to have that guide updated.

An attacker can get around this by running a botnet against you or opening up many concurrent connections (I think the latter can be capped), but I've rarely seen this. A botnet attack will defeat IP based blocking anyways. > Is it per user or per IP? Irrelevant -- there is no tracking. It's simply pauses the reply to bad auth attempts and tarpits the session. auth_failure_delay does not block BFD attacks, but makes it infeasable for reasonable strength passwords. It's simpler to implement, robust, and fault tolerant (e.g. a user cannot accidentally lock themselves out requiring administrative intervention to restore immediate access, or repeated failures from a NAT'd network does not DoS everything within the NAT'd network).

How to configure read-only access during a migration?
by Jeffrey Tunison 22 Oct '14

22 Oct '14

Hi. I would appreciate your advice about this PROBLEM: ======================================================= Find the simplest way to configure a Dovecot 2.2.10 IMAP server to access existing email users' (mbox-format) mail folders via a master_user ****in read-only mode.**** (I've got the master_user access working.) Simplest because while I'm proficient at UNIX systems administration, I'm under time pressure and dovecot has a lot of configuration flexibility. Identifying the right way to do this is proving time- consuming. Namespaces? ACL's? Passdb's? Mounting the mail-containing file systems in read-only mode did not work. (Would it have worked if I had disabled all file-locking rules (if so, how?)?) I thought it was time to bring in the dovecot wizards. You! GOAL: ======================================================= Without knowing or changing users' passwords, migrate several hundred users of dovecot IMAP to MS Exchange using the commercial product Transend. I'm manging the dovecot side, someone else is doing the Transend/Exchange piece. Migration would occur in batches due to slowness of the Transend side when dealing with users with email collections over a few gigabytes. I have a production IMAP server (dovecot 1.0.13 on 32-bit RHEL 4.9). Let's call it PROD for short. Users INBOXes are stored locally on PROD. Their other mail folders are stored on a second machine and accessed via NFS. Those other folders contain the great majority of the email to be migrated. Let's call the NFS server MIGR for short. On MIGR, I've set up a migration IMAP server (dovecot 2.2.10 on 64-bit RHEL 5.10). MIGR is a dedicated NFS server with newer hardware than PROD. It has an unused Ethernet NIC I can tell Transend to use. Both PROD and MIGR use NIS for authentication. Therefore PAM is consulted for passdb information, normally. No SQL db's used. I set up the second server (MIGR) for several reasons: 1) there are some users mail folders larger than the 32-bit file size limit found on the PROD server. 2) the bulk of the email is stored locally on the MIGR server. 3) the version of dovecot is much newer and therefore more likely to have fewer bugs and more configuration options. 4) I don't want to modify the production environment except where really necessary. Pointing Transend at MIGR instead of PROD seems like it will be faster and better. Telling end-users to use MIGR instead of PROD would allow them to verify that their email came across okay (into MS Exchange) without being able to modify the original copy of email (in Dovecot). In the days and weeks after migration. I'd like to disable access ***for a batch of users*** on the PROD server at the time the migration begins for that batch. I may need to re-enable access on PROD for certain users if the migration does not succeed. Transend has been dying on a number of test users despite tweaking its parameters in consultation with the vendor. "Corrupt" messages seem to be the issue. Users (or sysadmins) might be required to identify and delete the offending messages before we retry their migration. (Which folders and which messages are causing problems will hopefully be discernible in Transend logs.) Ha! If you've read this far, then I'd also say that I welcome any advice on changes to increase performance on MIGR, such as whether trying to minimize indexing as I've done is useful. Current configurations of the two servers follow. =========================================================================== PRODUCTION: =========================================================================== # 1.0.13: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log protocols: imaps imap listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_processes_count: 20 login_max_processes_count: 500 max_mail_processes: 1524 first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot-indexes/%u/ mbox_read_locks: dotlock mbox_write_locks: dotlock mbox_dotlock_change_timeout: 60 mbox_min_index_size: 2048 namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: Mail/ hidden: yes namespace: type: private separator: / prefix: ~/Mail/ hidden: yes namespace: type: private separator: / prefix: mail/ hidden: yes namespace: type: private separator: / prefix: ~/mail/ hidden: yes auth default: master_user_separator: * verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot.deny deny: yes passdb: driver: passwd-file args: /etc/dovecot.transend master: yes passdb: driver: shadow passdb: driver: pam userdb: driver: passwd =========================================================================== MIGRATION: =========================================================================== # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.18.1.el5 x86_64 Scientific Linux release 5.10 (Boron) auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no first_valid_uid = 100 log_path = /var/log/dovecot.log mail_debug = yes mail_location = mbox:~/Mail:INBOX=/var/spool/concmail/%u:INDEX=MEMORY mbox_min_index_size = 50048 B mbox_write_locks = fcntl 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 = } namespace one { hidden = yes location = prefix = Mail/ separator = / } namespace three { hidden = yes location = prefix = mail/ separator = / } passdb { args = /etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { args = /etc/dovecot/dovecot.transend driver = passwd-file master = yes } passdb { driver = pam } protocols = imap service imap-login { process_min_avail = 15 service_count = 10 } service imap { executable = imap postlogin process_limit = 2048 } service postlogin { executable = script-login -d rawlog } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } deny = yes driver = passwd-file } passdb { args = /etc/dovecot/dovecot.transend driver = passwd-file master = yes } passdb { driver = pam } protocols = imap service imap-login { process_min_avail = 15 service_count = 10 } service imap { executable = imap postlogin process_limit = 2048 } service postlogin { executable = script-login -d rawlog } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 1000 }

dictionary attack defense
by Cliff Hayes 22 Oct '14

22 Oct '14

Does dovecot have any dictionary attack defenses yet? In the past I have had to implement defense from outside dovecot, but since dovecot is at the front lines and therefore is the first to know I'm hoping by now there is something we can set. For example, a limit on access failures per minut/hour/day or some such. If not why not?

authenticate plain, and virtual users
by Eric Abrahamsen 22 Oct '14

22 Oct '14

I'm running dovecot 2.2.14 on Archlinux. I've been using it with the isync syncing utility for quite some time with no problems, using the LOGIN authentication mechanism. Recently Isync was updated to support PLAIN, and I'm having trouble moving to that. The authenticate string that isync is sending is not the one that dovecot is expecting. I suspect this is because of how I have virtual users set up on my machine. This is a personal laptop, no other users, and so I didn't want to go through the rigmarole of creating more system users just for mail accounts. I also wanted everything stored under my home directory. So my dovecot config looks like this: # 2.2.14: /etc/dovecot/dovecot.conf # OS: Linux 3.16.4-1-ARCH i686 auth_verbose = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_plugins = " fts fts_lucene" passdb { args = username_format=%u /etc/dovecot/passwd driver = passwd-file } plugin { fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. } protocols = imap ssl = no userdb { args = uid=eric gid=users home=/home/eric/.mail/%d/%n username_format=%u default_fields = mail=maildir:/home/eric/.mail/%d/%n/mail driver = static } My /etc/dovecot/passwd looks like this: eric@ericabrahamsen.net:{PLAIN}password1 eric@paper-republic.org:{PLAIN}password2 When isync tries to log into the local dovecot using PLAIN, it sends the base64-encoded version of this string: eric(a)paper-republic.org\0eric\0password2 With my current dovecot config, telnet experimentation shows that dovecot will accept either of these two: \0eric(a)paper-republic.org\0password2 eric@paper-republic.org\0eric@paper-republic.org\0password2 Ie, either with or without the authorization ID, just like it says at http://wiki2.dovecot.org/Debugging/Authentication Given that I'm unlikely to be able to change how isync sends the string (and that it's really doing the right thing), are there alterations I can make to my dovecot config to get it to accept the authenticate string that isync is sending? Ideally, can I do that without having to set up system users? I've already tried using the other fields in the passwd file, putting "eric" and "eric(a)paper-republic.org" into the UID fields, just in case. No dice. Thanks in advance for any advice! Eric

Multiple user attributes in LDAP userdb query strings
by BINOTTO Luis SIDOR 21 Oct '14

21 Oct '14

Hello list, I have an issue with dovecot and Ldap... Any help will be grateful... I have my virtual users stored in an Active Directory database. I am using 2 attributes in AD to locate the user account: mail (their primary email address) and proxyAddresses (a multivalue attribute containing their mail aliases). I also control the mount point in which the mail is located with another attribute in AD, in this case I used "pager". I have dovecot 1.2.15 and there are no immediate plans to upgrade it. I configured Dovecot's deliver process in order to integrate sieve capability. I have configured userdb ldap and passdb ldap in Dovecot and have set up master and client sockets. I am using maildir format for directory layout. The problem is to set the variables home and mail that will define the mail location. The format must be like this: home: /Mailboxes/<mount point>/<user login>/ mail: /Mailboxes/<mount point>/<user login>/Maildir So, for a particular user (Login: user1, smtp: user1(a)domain1.com, alias smtp: user1_alias(a)domain1.com) the variables will be: home: /Mailboxes/AdmUsers/user1/ mail: /Mailboxes/AdmUsers/user1/Maildir Active Directory has the values in: mail:(user1@domain1.com), proxyAddresses:(user1_alias@domain1.com), sAMAaccountName(user1). I have defined home and mail in dovecot-ldap.conf. # User attributes are given in LDAP-name=dovecot-internal-name list.

The variable home is set correctly (home: /Mailboxes/AdmUsers/user1/). The problem is when the mail is sent to the smtp alias, in which the variable home is set incorrectly (home: /Mailboxes/AdmUsers/user1_alias/). There is a way to set two values to user_attrs?, in this case I would need to set pager and sAMAccountName (instead of %u), to it. Thanking you in anticipation...

Proxy problem: "imap-login: Error: proxy(USERNAME): connect(10.x.x.178, 993) failed: Cannot assign requested address (after 0 secs, local=10.x.x.104)"
by Ralf Hildebrandt 21 Oct '14

After fixing the "duplicate compression" problem, we're now encountering "imap-login: Error: proxy(USERNAME): connect(10.x.x.178, 993) failed: Cannot assign requested address (after 0 secs, local=10.x.x.100)" in the logs. We already tried raising the ulimit, the max number of open files. Once we reach about 25k connections, we're getting the error above... for all local addresses. It seems as if the system cannot create any more outgoing connections.

Hello, after courier-dovecot-migrate.pl, the only folder appears in webmail menu is "Inbox". The others still are in Maildir "Maildir/.myfolder" and contains its "dovecot-uidlist" and "dovecot-keywords" files. May I need to edit some file? -- Saludos!!

Dovecot Auth Issue
by Austin Einter 21 Oct '14

21 Oct '14

Dear All I have been able to setup postfix and dovecot. Through command line, I can send mail out. Now I have installed roundcube in mail server side, and I am able to access like https://mydomain/webmail.com Login was failing. Then I debugged and modified settings in dovecot and using PAM for authentication. Now I trying to login to email server. I am not sure if authentication by dovecot and pam is successful. I enabled logging for dovecot. The below logs I get when a user "try" logs in.

SMTP authentication setup
by Brian 21 Oct '14

21 Oct '14

At my company we've had a longstanding problem of not being able to send email from devices outside of our internal network and any specific IP address that we open the relay to. As it turns out, SASL has never been set up. I need to set up SASL ASAP but none of the guides I've found seem to work. This is the latest guide I tried: http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL I did everything on here minus the last part because it's on the same server. Also, instead of submission inet n - - - - smtpd I did: 127.0.0.1:1025 inet n - - - - smtpd After all is done, however, I'm unable to send any mail. Thunderbird just says sending message but doesn't send and I don't even get an error. I end up having to disable SASL again before I can send mail. Dovecot version 2.0.9 Postfix version 2.6.6 CentOS 6 I have Postfix, Dovecot, and ASSP on the same server. Thanks everyone. -- This email was Virus checked by Astaro Security Gateway. http://www.sophos.com

90-sieve.conf syntax - moving from v2.0.x to v2.2.x
by deoren 21 Oct '14

21 Oct '14

Hi, I'm currently running version v2.0.x in production (using Maildir storage) and it's been working well. I'm interested in moving to version 2.2.x and am preparing a test server to do so. As I have been merging the conf file changes between the two versions I noticed syntax changes for the 90-sieve.conf file. There are now 'locations' and presumably to keep referring to local content I'll need to use the 'file:' location type. On my production box (v2.0.x) I have 90-sieve.conf configured like so: sieve = /var/vmail/sieve/%d/%n/.dovecot.sieve sieve_default = /var/vmail/sieve/global.sieve sieve_dir = /var/vmail/sieve/%d/%n/sieve_dir Inside of the /var/vmail/sieve/%d/%n/ directory (i.e., /var/vmail/sieve/example.com/testuser/) I find: drwxr-xr-x 3 vmail vmail 64 Oct 19 12:07 . drwxr-xr-x 9 vmail vmail 101 Jun 21 10:47 .. lrwxrwxrwx 1 vmail vmail 25 Jun 21 11:10 .dovecot.sieve -> sieve_dir/roundcube.sieve -rw------- 1 vmail vmail 3694 Oct 19 12:07 .dovecot.svbin drwx------ 3 vmail vmail 38 Oct 19 11:58 sieve_dir and that works well. I look at the current wiki documentation: http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration and I find that the 'seive_dir' conf option is still listed, but the comments for it appear very similar to the comments that precede the 'sieve' conf option in the stock 90-sieve.conf file: # The location of the user's main Sieve script or script storage. The LDA # Sieve plugin uses this to find the active script for Sieve filtering at # delivery. The "include" extension uses this location for retrieving # :personal" scripts. This is also where the ManageSieve service will store # the user's scripts, if supported. Assuming that the 'sieve' and 'sieve_dir' conf settings have not been merged into just 'sieve' (and that I need to use the 'file:' location specifier), is this how I would configure the two settings for Dovecot 2.2.x? sieve = file:/var/vmail/sieve/%d/%n;active=~/.dovecot.sieve sieve_dir = file:/var/vmail/sieve/%d/%n/sieve_dir If the two have been merged, how would I go about configuring the 90-sieve.conf file to get the same results? Thanks for your help.

replication sieve settings
by Martin Schmidt 20 Oct '14

20 Oct '14

Hello, can someone give me a hint, where to find an info, how to setup dovecote replication with sieve? On my active.active setup, it replicates the user mdboxes and sieve works also, on the active destination fileserver. Client changes the sieve, tests work fine. But the sieve file won't get replicated to the replica server. As i've researched, it was introduced in dovecot v2.2.rc3 Is it default, that doveadm replicator replicate '*' includes the sieve and i made a config error? Or is there an option to set for the replication service? On dovecot director server, i've set director in conf.d/20-managesieve.conf service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } } and added sieve to plugins in conf.d/20-lmtp.conf protocol lmtp { mail_plugins = $mail_plugins sieve } doveconf -n ... director_mail_servers = 192.168.200.10 192.168.200.11 director_servers = 192.168.200.1:9090 192.168.200.2:9090 disable_plaintext_auth = no doveadm_port = 24245 lmtp_proxy = yes 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 duplicate plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = " imap lmtp sieve pop3" ... service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } } ... protocol lmtp { auth_socket_path = director-userdb mail_plugins = " sieve" } ...

fixes for quota support on NetBSD
by Thomas Klausner 20 Oct '14

20 Oct '14

Hi! dovecot-2.2.13 already has quota support for NetBSD, but it's buggy. The attached patches by Manuel Bouyer <bouyer(a)NetBSD.org> fix the issues. There is one thing that's not nice in them: one include is now for "/usr/include/quota.h" since dovecot comes with its own file "quota.h" which is earlier in the search path. Perhaps dovecot's copy can be renamed to dovecot-quota.h or to some other non-conflicting name? Cheers, Thomas

last_login plugin with MySQL
by Luigi Rosa 20 Oct '14

20 Oct '14

Hi, I have a Dovecot test installation with MySQL userbase and authentication where I am trying to setup last_login plugin with SQL dictionary I read http://wiki2.dovecot.org/Plugins/LastLogin and I addes this to my configuration plugin { last_login_dict = sql:/etc/dovecot/dovecot-sql.conf.ext } mail_plugins = $mail_plugins stats protocol imap { mail_plugins = $mail_plugins imap_stats last_login } When I log in with IMAP I get this error: Error: last_login_dict: dict_init(sql:/etc/dovecot/dovecot-sql.conf.ext) failed: Unknown dict module: sql /etc/dovecot/dovecot-sql.conf.ext is the file taht contains the SQL configuration.

Maybe I'm able to reproduce the problem. :-) It's Solaris10 nroff, and GNU groff 1.19.1. Ancient stuff so I wouldn't spend too much time looking at it.

Just re-tried this, and it doesn't seem to fire getmail on access for me. My incrontab is as follows: /home/user/Maildir/cur/ IN_ALL_EVENTS,IN_ONESHOT /home/user/bin/mvmail.sh The incrontab rule does work, but only if I make a physical change in /home/user/Maildir/cur/ e.g. by moving a mail from another folder in there.

sieve folder separator
by Thomas Koch 19 Oct '14

19 Oct '14

Hi, I'm moving from one email provider (me) to another (mailbox.org) and observed that the new provider uses "/" instead of "." as a folder separator. Now I need to adapt my sieve script. It's not too much work and I can even just define a variable at the beginning of my script: set "SEP" "/" But it would be great, if SIEVE would come with a predefined constant for the folder separator. Or does this already exists and I didn't find it? Thank you, Thomas Koch

Hi, I'm currently running getmail in a cron job every 2 minutes, so I was quite intrigued by this on the wiki: http://wiki2.dovecot.org/HowTo/TriggerGetmailOnIMAPAccess Thing is - I couldn't see how it would work and, when I tried it, it didn't work (at least not for me). It details using incrontab to monitor /home/username/.maildir/cur in order to trigger getmail. However, "cur" won't change unless populated with mail...as an initial result of actually running getmail? Seems like a chicken and egg situation. I reckon I'm missing something fundamental :-), but what is it? Ta.

[Dovecot] Disk Encryption
by Simon Brereton 17 Oct '14

17 Oct '14

Hi As I understand it email headers need to be unencrypted (otherwise DKIM doesn't work). From the MUA to either Postfix, or Dovecot the connection is (or can/should be) secured with TLS/SSL. What I would like to know is if it is possible to encrypt the mailstore? Postfix is using Dovecot for delivery so it's only Dovecot that would need to encrypt/decrypt the mailstore. Is this possible? Is there a terrible reason to do it even if it is possible? I realise that from MTA to MTA there's no guarantee of encryption (and in fact it's very unlikely unless keys have been exchanged), but my primary goal is supplement the physical security of the mail store of mails we already have or have sent. Mostly just idle curiosity as to what has been done, or what could be done. What is worth doing is a separate thread entirely. Thanks. Simon

High memory usage
by Hanna Ruotsalainen 17 Oct '14

17 Oct '14

Hi I recently (about 2 weeks ago) moved over my users over to a new version of dovecot (2.0.9) and now the memory usage on the new server seems much higher than it was before. The new server is a CentOS 6 VM with 4 GB of RAM and 4 CPUs and according to top, it's used up all of the RAM and all of the Swap. Here's a sample of the output from top (sorted by allocated memory). top - 10:42:36 up 22 days, 21:57, 1 user, load average: 1.04, 1.40, 1.52 Tasks: 1643 total, 1 running, 1642 sleeping, 0 stopped, 0 zombie Cpu(s): 0.7%us, 0.7%sy, 0.0%ni, 93.3%id, 5.1%wa, 0.0%hi, 0.1%si, 0.0%st Mem: 3924432k total, 3779236k used, 145196k free, 23740k buffers Swap: 4063228k total, 3181164k used, 882064k free, 156420k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 16738 root 20 0 399m 182m 436 S 0.0 4.8 5:50.58 config 18790 dovenull 20 0 54528 11m 2036 S 0.0 0.3 0:00.05 imap-login 22277 dovenull 20 0 54528 11m 2156 S 0.0 0.3 0:00.04 imap-login 22796 dovenull 20 0 54528 11m 2140 S 0.0 0.3 0:00.03 imap-login 22749 dovenull 20 0 54528 11m 2148 S 0.0 0.3 0:00.03 imap-login 22825 dovenull 20 0 54528 11m 2156 S 0.0 0.3 0:00.03 imap-login This is with 1015 imap processes and 484 imap-login processes. The old version was 1.0.rc15 and running on a CentOS 4 box with 2GB of RAM. It was overloaded but the RAM usage wasn't maxed out like this one is (not much swap usage and a large amount of cached memory). Is this amount of memory usage normal? What could be causing it, if it isn't?

User logs into managesieve on node1 and uploads a script. The %n/.sieve/managesieve.sieve and the symlink .dovecot.sieve -> .sieve/managesieve.sieve is created as expected.

Re: Unable to get virtual users set up with database auth
by Gedalya 17 Oct '14

17 Oct '14

When you reply, try to make sure you reply to the list (dovecot(a)dovecot.org) in Thunderbird you should have a Reply List button, or just use reply to all. btw I meant: the output of the 'dovecot -n' command, sorry :D OK so, first of all, lda doesn't do any passdb lookup at all, only userdb. It doesn't have any password to check. Just as a comment, your password query could just as well be: password_query = SELECT uPass as password FROM users WHERE uName = '%n' AND uDomain = '%d' auth_username_format = %Lu -- which I believe is set by default, would lowercase the username for you on the way in from the client, so if all your usernames are meant to be purely lowercase, there is no need to return these fields from the database. Set it explicitly just to be sure. You're using a somewhat old version, I'm not sure how it was back then. Either way, this shouldn't be affecting lda. Now, this seems to be wrong. mail_location = mbox:/var/spool/mail/%u:INBOX=/var/spool/mail/%u You probably want it more like: mbox:~/mail:INBOX=/var/spool/mail/%u The first value, ~/mail, will be a /mail directory under the 'home' directory set in your static userdb, and that's where mailboxes (folders) other than INBOX will be stored. It must be a directory, not a file! I'm a little confused about some of the other details in your log. Let's try to correct your mail_location first and see where that takes us. Also, under namespace, you might as well comment out the 'location = ' and 'prefix = ' lines, though I'm not sure it matters.

dsync duplicating identical messages
by Bruno Viaris 16 Oct '14

16 Oct '14

Dear list, I’m trying to setup dovecot/postfix/getmail for a single user application: I have 3 email accounts and 2 main computers (home and work). I want to have an imap server on each machine with sync/replication so that read/reply/delete status and sorting into folders are identical. This part is achieved via dsync and seems to work. Messages are fetched from my ISPs with getmail on both machines. The problem I have is that dsync does not see that a message already fetched on both sides is identical, and duplicates it. I use sdbox (because I like the compression option and the separate storage of attachments). The content of the messages (headers and body) are identical, but the sdbox files have differences in the header and/or trailer. In fact, for each incoming message, I get 4 slightly different files (2 on each machine). Do you know where I could find documentation on how dsync compares messages, and also on sdbox file format ? If you explain me that there is no way to prevent this duplication and that anyway dsync does the right thing, I will probably use getmail only on one machine and let dsync propagate the messages to the other site, but I will miss the redundancy (and some speed) of my wished setup... Thanks -- Bruno P.S. : Background: Home has DSL with 10 MBit/s down and 1 MBit/s up, and full control over NAT / firewall Work internet access is limited by the 100 MBit LAN and has strict firewall and complicated VPN. So it is not easy for my home email client to access the imap server of my work machine, and it is slow for my work email client to access my home imap server. I don’t trust any company for archiving my emails.

Unable to get virtual users set up with database auth
by Cliff Hayes 16 Oct '14

16 Oct '14

I can't seem to get imap virtual users to work with database authentication on new Scientific Linux 6.5 server with Sendmail 8.14.4 & Dovecot 2.0.9 Apparently I have to also create system users because sendmail/procmail/dovecot want to check directory ownership. So I created a database, made entry for the user, created the user chayes on the system. But %u always contains just chayes instead of chayes(a)domain.tld even though I tried different select statements to put the entire username in the username field. This causes the following errors: Oct 16 00:10:26 avalon sendmail[2536]: s9G5APo9002535: forward /var/spool/mail/chayes(a)domain.tld/chayes/.forward.avalon: Group writable directory Oct 16 00:10:26 avalon sendmail[2536]: s9G5APo9002535: forward /var/spool/mail/chayes(a)domain.tld/chayes/.forward: Group writable directory Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Effective uid=497, gid=497, home=/var/spool/mail/chayes(a)domain.tld/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Home dir not found: /var/spool/mail/chayes(a)domain.tld/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Namespace : type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:/var/spool/mail/chayes:INBOX=/var/spool/mail/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: fs: root=/var/spool/mail/chayes, index=, control=, inbox=/var/spool/mail/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Error: user chayes: Initialization failed: Namespace '': mbox: mbox root directory can't be a file: /var/spool/mail/chayes (http://wiki.dovecot.org/MailLocation/Mbox) Oct 16 00:10:26 avalon dovecot: lda(chayes): Fatal: Invalid user settings.

[Dovecot/VirtualUsers/VirtualMailBoxes] No mails into mua
by aleskandro 16 Oct '14

16 Oct '14

Hi all, I've configured postfix with multiple host and virtual mailboxes (main.cf is here: http://pastebin.com/798VVxbv) So I can receive email to vuser(a)mydomain.tld into /var/mail/vhosts/mydomain.tld/vuser file. Now I'm configuring dovecot 2.2.13-r1; this is my dovecot -n and /etc/dovecot/passwddir/mydomain.tld/passwd: http://pastebin.com/b4xcjj7t - The auth and server subscribe from a mua is ok and in the vuser file there are some mails but I can't see them in my mua. mail.log doesn't report any error. Where I'm wrong? Aleskandro

Strange quota warning behavior
by Gordon Grubert 16 Oct '14

16 Oct '14

Hi, we are using dovecot 2.2.14. So far, we used the following quota warning configuration quota_rule = *:storage=10G quota_warning = storage=90%% quota-warning 90 %n quota_warning2 = storage=80%% quota-warning 80 %n quota_warning3 = storage=70%% quota-warning 70 %n This works fine. Now, we wanted to add the all clear feature for the quota warning by adding this line: quota_warning4 = -storage=70%% quota-warning 70 %n below The result is really strange. Test 1: 70% exceeded: warning3 executed => OK fall below 70%: quota_warning2 executed => NOT OK quota_warning4 executed => OK Test 2: 70% exceeded: warning3 executed => OK 80% exceeded: warning2 executed => OK fall below 80% (but still more than 70%): quota_warning executed => NOT OK fall below 70%: quota_warning2 executed => NOT OK quota_warning4 executed => OK At the moment, we are running the minimal configuration quota_warning = storage=70%% quota-warning 70 %n quota_warning2 = -storage=70%% quota-warning 70 %n below working like expected (warning when exceeding 70% and all clear when falling below 70%). Does anybody know if there is an error in our configuration or maybe, could this be a bug in dovecot? Best regards, Gordon -- Technischer Leiter & stellv.

index problem with only 1 folder of 1 box
by Guillaume 16 Oct '14

16 Oct '14

Hello, First of all, sorry for my poor english level. I pass to solr indexing. All is OK, except for the inbox of one of the mailboxes. For this inbox (other folders of the same mailbox have no problems), when i do text search, there is always no response. Others mailboxes have no problems. If i do a : "doveadm -Dv fts rescan -u mybox(a)domain.tld", i can do one and only one search with the correct response. It index the folder, take a few seconds and give me the good answer. If i redo the same search, it's extremly quick with no answers. It's like a cache problem but i don't know where and why... Logs are not very verbose...

pop3-login segfaulting

I upgraded dovecot from v1 to v2 as part of a CentOS upgrade (5.6->6.5) and am now running on 2.0.9. Any time I connect to the pop or imap ports however I get "master: Error: service(imap-login): child 2860 killed with signal 11 (core not dumped - add -D parameter to service imap-login { executable }" after following the core dump instructions at http://www.dovecot.org/bugreport.html. The problem is that I'm not sure how these processes are spawned in order to add the switch. Can I spawn them directly? If so, I ought to be able to do an strace to track down the issue as well.

mmap_disable=yes not honored always
by Peter Benko 15 Oct '14

15 Oct '14

Hi all, I'm experimenting with having the mail store on a 9p file system that lacks mmap() functionality. So I disabled it in dovecot: mmap_disable = yes However, I keep getting the following error messages in my log: Oct 15 16:55:00 computer-name dovecot: imap user(a)domain.com[192.168.1.3] Error: mmap() failed with file /mail/mailboxes/domain.com/user/indexpvt-accounts/other-user/mailboxes/INBOX/dovecot.index.pvt.log: Invalid argument I only get those messages for the shared folder's private indexes. This setup works perfectly on an ext2/3/4 fs. Any opinions, is this a bug? Is mmap_disable not mandatory for all operations? Best regards, Peter

permissions when moving mails
by Alexander 'Leo' Bergolth 15 Oct '14

15 Oct '14

Hi! I am using Unix groups to control access to shared mailboxes. This works fine as long as files are not moved between mailboxes that are owned by different groups. The move operation doesn't change group ownership of the mail. Is there a way to force dovecot to e.g. inherit the ownership from the parent folder, not only for new messages bot also for messages moved from one folder to another? The wiki says: http://wiki2.dovecot.org/SharedMailboxes/Permissions -------------------- 8< -------------------- When mails are copied between Maildirs, it's usually done by hard linking. If the source and destination directory permissions are different, Dovecot create a new file and copies data the slow way so that it can assign the wanted destination permissions. The source and destination permission lookups are done only by looking at the mailbox root directories' permissions, not individual mail files. This may become a problem if the mail files' permissions aren't as Dovecot expects. -------------------- 8< -------------------- Does dovecot only look at the permissions or does it also take user/group ownership into account? The behavior I experience is that even though the mailbox directories are owned by different groups, dovecot doesn't copy the mails. (See my example below.) Setting maildir_copy_with_hardlinks = no seems to fix the problem but maybe this behavior should be considered as a bug? I am using dovecot 2.2.14 and maildir mailboxes.

Dbox and Exim
by C Peters 15 Oct '14

15 Oct '14

The Dovecot wiki [1] doesn't list either Exim, Postfix or anything else as supporting the dbox. I did some searching in the Exim archives and have found only one message mentioning dbox, sdbox or mdbox. [2] I think an RFC would go a long way towards getting the format supported. Has Timo, or anyone else, considered submitting an RFC to the IETF? My question was how are we going to use it if Exim doesn't support it. It looks like we can filter it and convert it with dovecot-lda. [3] I have generally avoided using Procmail for a few years because of various problems and it's a dead software project that hasn't been developed in what 15 to 20 years. I am thinking about trying it with Exim's built in Maildrop filtering support. Has anybody tried that? What else are people using to enable dbox? The more specific question on the problem I am trying to solve. I have been using mbox for years, and I can't even get Dovecot, IMAP and Thunderbird working on the LAN because it can't handle the GB's of old mail. Mutt works on the local machine, but I want something that works while I am using something other than ssh and mutt. For example I want to try Mailpile and K9. I would like to try dbox, but given it's lack of support in Exim or Postfix, I'll probably convert to maildir.

Proxy problem: "[COMPRESSIONACTIVE] TLS compression already enabled"

bandwidth shaping
by Alan Bailward 14 Oct '14

14 Oct '14

Hey all, sorry if this has been asked before, but I haven’t really found a good solution. I have a mac at home and randomly, maybe once a week or once a month, Mail.app will go crazy and use as much bandwidth as I have to pull down mail. I’m not home so I can’t tell what it’s done or why, and sometimes it stops after an hour, sometimes it goes all night, leaving me with a potentially big bandwidth bill for my colo’d server which hosts my mail (dovecot 1.2.9, postfix 2.7.0 on Ubuntu LTS 10.04). I’m wondering if there’s a way to restrict bandwidth that’s the “accepted” and proper way with dovecot? There isn’t anything (AFAICT) built into dovecot, and the alternative seems to be setting up bandwidth shaping with ‘ip’, but that is a pretty horrible nest of ugliness. Is there a fairly simple setup to set it so imap/pop traffic can only ever use 1mb/s (or some arbitrary number)? I’m not looking for a one liner, but each time this happens I say “I’m going to figure this out and fix this”, then get lost in ip and shaping queues and give up in frustration until the next time it happens, when I say “I’m *really* going to figure this out this time…”. Anyone have any pointers? TIA Alan

auth-worker goes wild
by Hans Morten Kind 14 Oct '14

14 Oct '14

dovecot-2.2.13 running on Solaris-10, app 5000 concurrent connections, and a pretty standard config where passdb is set up with driver = pam. We have had some situations where an auth-worker gets into a loop, the load on the server rises and the auth-master seems blocked untill finally no new imap nor pop session are accepted. A 'doveadm reload' restores normal operations. With debug logging enabled we are observing this: auth: Debug: pam(,10.10.30.33,<7WMu3UkEGQCBsR4h>): cache miss auth-worker(24556): Debug: pam(,10.10.30.33): lookup service=dovecot auth-worker(24556): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: ... auth-worker(24556): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: etc etc After some time dovecot only logs Warning: Auth process not responding, delayed sending initial response (greeting) Disconnected: Auth process broken (disconnected before auth was ready, waited 26 secs) 'truss -wall -aep PID' on the looping auth-worker shows the loop: 0.0757 write(2, 0x080AE0C0, 71) = 71 0101 2 4 5 5 6 p a m ( , 1 0 . 1 0 . 3 0 . 3 3 ) : # 1 / 1 s t y l e = 2 m s g = P l e a s e e n t e r u s e r n a m e : \n 0.0826 write(2, 0x080AE0C0, 71) = 71 0101 2 4 5 5 6 p a m ( , 1 0 . 1 0 . 3 0 . 3 3 ) : # 1 / 1 s t y l e = 2 m s g = P l e a s e e n t e r u s e r n a m e : \n The host at 10.10.30.33 is running RoundCube for app 1000 concurrent users. This problem started after we provided our users RoundCube, and every time we end up in this stuck situation, it is the RoundCube-server making the connections where the username has zero length. I am unable to reproduce how RoundCube puts dovecot into this mess. With the enclosed patch installed, the loop terminates and normal operation are restored immediately: auth: Debug: pam(,10.10.30.33,<Q8kV6AEFYwCBsR4h>): cache miss auth-worker(18658): Debug: pam(,10.10.30.33): lookup service=dovecot auth-worker(18658): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: auth-worker(18658): Fatal: NO USER? auth-worker(18658): Error: Raw backtrace: 0xfef0798c -> 0xfef06d3b -> 0x807ca6e -> 0xfecc460e -> 0xfecc1d1e -> 0xfe3c0af4 -> 0xfecc2608 -> 0xfecc27f1 -> 0x807cc5e -> 0x807d162 -> 0x807d310 -> 0x8069ca1 -> 0x806ab72 -> 0x806aeec -> 0xfef1e866 -> 0xfef2001c -> 0xfef1e9ff -> 0xfef1e956 -> 0xfeeb0172 -> 0x8071bf2 -> 0x805a650 auth: Error: auth worker: Aborted PASSV request for : Worker process died unexpectedly I think however, that the pam driver should not have been initiated when the username has zero length, definitely there is nobody around to answer the prompt for a username ... hmk

Doveadm quota recalc sets quota for wrong quota root
by Rick van den Hof 14 Oct '14

14 Oct '14

Hi, In our setup, we use two quota roots. One for user quota and one for domain quota. If a user has no quota, then the domain quota is applied. For a user with user quota this is how it looks: # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 0 102400 0 User quota MESSAGE 0 - 0 In this case, the whole domain contains 21257 messages but the account itself contains 0. For a user with only domain quota, this is how it looks: # doveadm quota get -u rick(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 693299 - 0 User quota MESSAGE 12876 - 0 So far so good. My account contains 12876 messages. Now I've sent a message containing a 1mb.bin as attachment to test(a)shellz.nl: # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1440540 2560000 56 Domain quota MESSAGE 21258 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0 Seems to be fine, the message on disk is indeed 1.4MB and this has been added to both domain and user quota. Now see what happens when I run the following command: # doveadm quota recalc -u test(a)shellz.nl # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1384 2560000 0 Domain quota MESSAGE 1 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0 The recalc action has updated the domain usage to reflect the specific user's usage (my 12876 messages are no longer counted). We log domain usage (usage_domain) in a seperate table from mailbox usage (usage_mailbox). These are the queries that set the usage: 256 Query BEGIN 256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl' 256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl' 256 Query INSERT INTO usage_domain (bytes,domain) VALUES ('1418118','shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118' 256 Query INSERT INTO usage_domain (messages,domain) VALUES ('1','shellz.nl') ON DUPLICATE KEY UPDATE messages='1' 256 Query COMMIT 257 Query BEGIN 257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test(a)shellz.nl' 257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test(a)shellz.nl' 257 Query INSERT INTO usage_mailbox (bytes,userdomain) VALUES ('1418118','test(a)shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118' 257 Query INSERT INTO usage_mailbox (messages,userdomain) VALUES ('1','test(a)shellz.nl') ON DUPLICATE KEY UPDATE messages='1' 257 Query COMMIT How do I prevent this from happening? It should only update the usage_mailbox table when I run the recalc command. Could this be because we use seperate tables for domain and user usage? dovecot -n: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-37-generic x86_64 Ubuntu 14.04.1 LTS auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890+=_.-@& dict { expire = mysql:/etc/dovecot/dovecot-sql-expire.conf quotadomaindict = mysql:/etc/dovecot/dovecot-sql-quota-domain.conf quotauserdict = mysql:/etc/dovecot/dovecot-sql-quota-user.conf } disable_plaintext_auth = no listen = *,[::] mail_fsync = never mail_location = maildir:~/Maildir mail_plugins = quota expire 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 passdb { args = /etc/dovecot/dovecot-sql-user.conf driver = sql } plugin { expire = Trash expire2 = Spam expire_dict = proxy::expire mail_log_events = delete copy save expunge mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:Domain quota:%d:proxy::quotadomaindict quota_rule2 = Trash:ignore quota_warning = storage=99%% doquotawarning 99 %u quota_warning2 = storage=95%% doquotawarning 95 %u quota_warning3 = storage=75%% doquotawarning 75 %u quota2 = dict:User quota::proxy::quotauserdict quota2_rule2 = Trash:ignore quota2_warning = storage=99%% doquotawarning 99 %u quota2_warning2 = storage=95%% doquotawarning 95 %u quota2_warning3 = storage=75%% doquotawarning 75 %u } protocols = imap pop3 service auth-worker { unix_listener auth-worker { mode = 0600 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } unix_listener auth-userdb { mode = 0600 user = vmail } user = vmail } service dict { unix_listener dict { mode = 0600 user = vmail } } service doquotawarning { executable = script /usr/bin/doquotawarning.py unix_listener doquotawarning { user = vmail } user = vmail } service imap-login { chroot = process_limit = 200 process_min_avail = 2 } service imap { executable = imap postlogin } service managesieve-login { chroot = } service pop3-login { chroot = process_limit = 50 process_min_avail = 2 } service pop3 { executable = pop3 postlogin } service postlogin { executable = script-login /usr/local/postfixint/dolastlogin.py user = $default_internal_user } ssl_cert = </etc/ssl/certs/wild.totaal.net/wild.totaal.net.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/certs/wild.totaal.net/wild.totaal.net.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql-user.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_logout_format = bytes=%i/%o mail_max_userip_connections = 50 mail_plugins = quota imap_quota mail_log notify expire } protocol pop3 { mail_max_userip_connections = 50 mail_plugins = quota expire pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s, bytes=%i/%o pop3_uidl_format = %f } protocol lda { deliver_log_format = msgid=%m: %$ mail_fsync = optimized mail_plugins = quota sieve expire postmaster_address = hostmaster(a)vps04.totaal.net rejection_reason = Your message to <%t>' was automatically rejected:%n%r } dovecot-sql-quota-domain.conf: connect = xxx map { pattern = priv/quota/storage table = usage_domain username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = usage_domain username_field = domain value_field = messages } dovecot-sql-quota-user.conf: connect = xxx map { pattern = priv/quota/storage table = usage_mailbox username_field = userdomain value_field = bytes } map { pattern = priv/quota/messages table = usage_mailbox username_field = userdomain value_field = messages } Thanks in advance to anyone who might be able to shed some light in this situation :).

Sorry for the replay to sender instead of the list. As I originally wrote, my need is script or a command like the old Expire_mail.pl that parse a local mbox folder and move/copy mail older than NN days to another local mbox folder. Probably for a Perl programmer is only matter of modify this script or something similar. I searched in docs, wiki, ... but not noticied something that can simply be inserted in a cron job to do the work. Only migration tools or complex (for me), library that can be used to manipulate folders :-) Thanks, F.

[Pigeonhole Sieve interpreter] :create argument and lda_mailbox_autosubscribe setting
by Vivien Lacourba 14 Oct '14

14 Oct '14

Hi, I am using dovecot and dovecot-sieve packages from Debian Wheezy (2.1.7-7+deb7u1). I noticed that while using ":create" (from the mailbox extension) in my Sieve filter and "lda_mailbox_autosubscribe = yes" in Dovecot's LDA config it automatically subscribes to the destination mailbox even if that mailbox already existed. Reading Dovecot's documentation and the mailbox extension RFC it seems subscription should happen only if it is a newly created mailbox and should not happen if the mailbox already existed. http://tools.ietf.org/html/rfc5490#section-3.2 [[ 3.2. ":create" Argument to "fileinto" Command (...) If the mailbox already exists, this argument is ignored. (...) ]] /etc/dovecot/conf.d/15-lda.conf [[ # Should automatically created mailboxes be also automatically subscribed? lda_mailbox_autosubscribe = yes ]] Also I noticed that if I don't use ":create" in my filters and instead set "lda_mailbox_autocreate = yes" in Dovecot's LDA config, then this time the behavior looks correct as the automatic subscription will only happen for a newly created mailbox.

Larry & Pascal, Thanks for the reply.

To dovecot-ee or not to dovecot-ee
by Jens Dueholm Christensen 13 Oct '14

13 Oct '14

Hi At the moment I'm running an ageing 2.0.13 install that need to be upgraded and moved to new HW. I was looking around, and saw that dovecot-ee is listed as a "free" (ie. 0$) product on dovecot.fi. Apart from the need to register an account in order to "purchase" an -ee license, are there any cavats by switching to the -ee version compared to compiling and running the regular releases? I've got no problems with downloading, building and installing the normal releases and I have no need for object storage, so will the -ee version give me anything else but access to a YUM repo and RPM packages? Regards, Jens Dueholm Christensen Survey IT

Dovecot domain quota
by Filip Bartmann 13 Oct '14

13 Oct '14

I have dovecot version 2.1.7 and I have quota configured as: ----------------------------------- dict { quota_domain = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } mail_plugins = quota protocol imap { mail_plugins = quota quota imap_quota } plugin { quota = dict:domain:%d:proxy::quota_domain quota_rule = *:storage=1M quota_rule2 = Trash:storage=+100M } ----------------------------------- /etc/dovecot/dovecot-dict-sql.conf.ext: ----------------------------------- map { pattern = priv/quota/storage table = quota_dict username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = quota_dict username_field = domain value_field = messages } map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } ----------------------------------- But the problem is that quota table created as: ----------------------------------- CREATE TABLE `quota_dict` ( `domain` varchar(255) NOT NULL, `bytes` bigint(20) NOT NULL DEFAULT '0', `messages` int(5) NOT NULL DEFAULT '0', PRIMARY KEY (`domain`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ----------------------------------- counts quota only for last user as defined /etc/dovecot/users or in database table. So if I have in /etc/dovecot/users (the contents is from testing VPS): ----------------------------------- test@debian.jd:{plain}radegast:8:8::/srv/mail/debian.jd/::userdb_quota_rule=*:storage=500k bartmann@debian.jd:{plain}radegast:8:8::/srv/mail/debian.jd/::userdb_quota_rule=*:storage=500k ----------------------------------- After running `doveadm quota recalc -A` I have in my db: ----------------------------------- +-----------+--------+----------+ | domain | bytes | messages | +-----------+--------+----------+ | debian.jd | 505758 | 81 | +-----------+--------+----------+ ----------------------------------- whith is from account bartmann(a)debian.jd not both accounts at testing VPS domain debian.jd. The same is with quota enforcing - quota if enforced on the latter of the accounts in /etc/dovecot/users on testing machine or database in production machine. What I do wrong? Thanks Filip Bartmann

delete/archive old mail
by sottilette＠rfx.it 13 Oct '14

13 Oct '14

Hi everybody, I store user's mail in the old mbox format. I have many scripts to manage users that works fine with mbox. I use the very old Expire_mail.pl script to delete mail older than NN days for selected users (nightly cron job). Still works fine with my CentOS dovecot-2.0.16. Now I want move the mail to a sort of archive folder instead of simply deleting it from the inbox for some users. Is there a similar script or some simple triks? Thanks, F.

2.2.14rc1 - dsync in backup mode still changes source permissions
by Peter Mogensen 13 Oct '14

13 Oct '14

Hi, It seems we are still able to reproduce this: http://www.dovecot.org/list/dovecot/2014-May/096367.html However... there's no longer any error-messages. It just silently changes permissions on some dovecot files in the source maildir. (most often dovecot-uidlist) We're running dsync as root, with hardwired userdb values for other reasons. So it has the OS permissions to change source. But still, running in "backup" shouldn't change source ever, should it? The command line is of this format - running on destination-host: # dsync -R -o mail_home=/users/user/maildir backup ssh -c arcfour -o StrictHostKeyChecking=no -i /root/.ssh/id-rsa-dsync source-host "dsync -o mail_home=/users/user/maildir" /Peter

Permissions for shared mail don't work
by Damien Desfontaines 12 Oct '14

12 Oct '14

Good morning, I'm using dovecot v.2.1.7 on Debian Sid, and the output of dovecot -n is available here: http://paste.fulltxt.net/C-O I'm trying to make the mailbox of (system) user "spam" available to user "ted". I followed these instructions: http://wiki2.dovecot.org/SharedMailboxes/Permissions and it doesn't seem to work. To be more precise: - I manually (and recursively) changed the permissions of all files in ~spam/Mail to 660 (and 770 for the directories); - I manually (and recursively) changed the group owner of everything in ~spam/Mail to "mailperso", where "mailperso" is a group whose users are spam and ted; - I added « mail_access_groups=mailperso » into my dovecot config; - and I restarted dovecot. But still, when I send a new email to spam, it appears as being owned by group "spam" and having permissions set to 600, so I can't access it with user "ted". I also tried to set the setgid bit for ~spam/Mail, it didn't change anything, and when I recursively set the setgid for all subdirectories of ~spam/Mail, it gives new mails the correct group (mailperso) but not the correct permissions. Have I missed something, or is this a bug? Thanks in advance and best regards, Damien

Hi, I'm new to dovecot, and I was reading the manual, to use SQL auth along with virtual domains. So far, it's perfect and does what I need, except for one thing. For each new user, does the directories on the filesystem will be auto-created on 1st login? Thanks in advanced,

dovecot replication (active-active) - server specs
by Martin Schmidt 11 Oct '14

11 Oct '14

Hello, i have some questions about the new dovecot replication and mdbox format. my company has currently 3 old dovecot 2.0.x fileserver/backend with ca. 120k mailboxes and ca. 6 TB data used. They are synchronised per drbd/corosync. Each fileserver/backend have ca. 40k mailboxes im Maildir format. Our MX server is delivering ca. 30 GB new mails per day. Two IMAP proxy server get the connections from the users. Atm. without dovecot director. We've got around 700k connections per day (imap 200k / pop3 500k) The system is getting issues because the fileserver still have old slow HDDs. Users sometime get connection timeouts, because the fileserver can not answer fast enough due to I/O waiting lag. So we want to make a new system. We desire the new system to use mdbox format ( bigger files, less I/O) and replication through dovecot replication (active/active) instead of drbd. Each fileserver should know every mailbox/user and for the time being 2 dovecot proxies for the user connections (IMAP/POP). (later after the migration from the old system to the new, dovecot director instead of proxies, for caching reasons). we've got 2 new fileservers, they have each SSD HDDs for "new-storage" and 7200rpm SATA HDDs on RAID 5 with 10 TB for "alt-storage" 32 GB RAM per Server Do you have some tips for the system? Do you believe 32 GB RAM are enough for one fileserver each and have you experience with the I/O Waiting problem with huge amounts of Data on the alt-storage? Could there be issues with the RAM, if one fileserver has a downtime, so the second one has to take over all mailboxes for a short amount of time? In general are only 2 new fileserver enough or should we think in bigger dimensions, like 4 fileserver Storage expansion in the new servers should not be a problem (bigger HDDs and a few slots free, so we can expand the raid 5). thank you kind regards Martin Schmidt

Dear Mailing List, (version and dovecot -n at the bottom) (Sorry for the bad English in this mail :) ) I'm new to dovecot and wanted to build my own mailserver using dovecot+postfix. I currently have a Problem with Permissions with my mailfolder. I could solve it easily if i set it with chmod to 777. but thats no real solution. While reading my log files i see a lot messages like: Oct 10 05:19:52 lda(owncloud): Error: user owncloud: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/home/vmail/example.com/owncloud/mail) failed: Permission denied (euid=100(owncloud) egid=1004(owncloud) missing +x perm: /home/vmail, dir owned by 5000:5000 mode=0700) Oct 10 05:19:52 lda(owncloud): Fatal: Invalid user settings. Refer to server log for more information. So Currently two Users need to acces the mail-folder: 1. The user itself (here: owncloud) 2. The vmail user I want to use dovecot with virtual users. Now the question is: shouldn't the directory be accessed only by the vmail user? and not by the owncloud user? Second Quest: If it's correct that the access is made by 2 users: what rights do they need? I Cant add all users to the group vmail and set g+rwx Permissions (every user could read mails from other users, and even edit them!) Thanks a Lot.

]UG] Dovecot 2.2.9 SSL client cert verification fails: openssl verify: OK
by Daniel Dickinson 11 Oct '14

11 Oct '14

Greetings all, I have verified a bug that has long been attributed to lack of knowledge on the part of the user. Dovecot rejects StartSSL client certificates due to reject StartSSL root CA when doing client verification even though the appropriately constructed ca-bundle.pem has been created and applied vi ssl_ca = </etc/dovecot/ca-bundle.pem. openssl verify -CAfile ca-bundle.pem -crl_check_all -policy_check -x509_strict -verbose client-cert.pem returns: client-cert.pem: OK However dovecot reports the following: Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: unable to get local issuer certificate: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: certificate not trusted: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Valid certificate: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Client CA Also reports the client certificate as valid. The certificate bundle was created as follows: openssl x509 -in sub.class1.client.pem -subject -issuer >ca-bundle.pem cat class1-client-crl.pem >>ca-bundle.pem openssl x509 -in startcom-root-ca.pem -subject -issuer >>ca-bundle.pem cat startcom-root-ca-crl.pem >>ca-bundle.pem Furthermore exim, Thunderbird, and Firefox are all perfectly happy with the certificates (and exim has no problem verifying the client certificates). Further, there are many more messages regarding issues with users of dovecot having issues with StartCom client certificates who have reported following all the steps than with Cyrus or Courier. Oh, and client verification of server-side certificate works fine with server-side certificate bundle (cat server.pem startcom-intermediate.pem startcom-root-ca.pem >dovecot.pem) Relevant dovecot -n included below: auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 otp auth_ssl_require_client_cert = yes auth_verbose = yes ssl = required ssl_ca = </etc/dovecot/ca-bundle.pem ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem ssl_verify_client_cert = yes verbose_ssl = yes OS is Debian Wheezy with latest updates and (just today in hopes it had been fixed, same error occurs with Wheezy's dovecot = 2.1.7) dovecot 2.2.9 from backports. amd64 architecture.

Migrating to Dovecot EE

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone! I am currently running dovecot 2.2.9 on my Debian Wheezy system. As this version is a bit outdated and I'm not too keen on compiling Dovecot myself I was thinking about moving to the Dovecot EE repository. I already have access to the repository, and now before I starting "apt-getting" all kinds of packages: What would be the best way on moving to the Dovecot EE repository? Just doing an apt-get install dovecot-ee? Will it replace the current version? Or should the old version be removed before installing the new one?

Second Quest: If it's correct that the access is made by 2 users: what rights do they need? I Cant add all users to the group vmail and set g+rwx Permissions (every user could read mails from other users, and even edit them!) Thanks a Lot.

Keywords & sync
by Ralf Hildebrandt 10 Oct '14

10 Oct '14

We're using keywords within Thunderbird, and we're syncing those using IMAP. When using more than 5 keywords, we're envcountering problems - they're only partially being synced (between two clients, but not all clients). Any idea why this could be happening? The introduction of tagging in Thunderbird is described here: <https://bugzilla.mozilla.org/show_bug.cgi?id=114656> -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Send an alert on master user login
by Andre Rodier 09 Oct '14

09 Oct '14

Hello, I want to know if there is an option in Dovecot to send an alert, or run a script when someone is using the master user facility. I can do something myself with fail2ban, but maybe there is an option in Dovecot? Thanks. André.

Sieve filter extracting wrong header value on certain mail messages
by gowen (dovecot) 09 Oct '14

09 Oct '14

# 2.2.12: /etc/dovecot/dovecot.conf # OS: Linux 3.15.4-x86_64-linode45 x86_64 openSUSE 12.3 (x86_64) Short version: 1) I filter out spam by using a dovecot sieve filter to act based on a header inserted by bogofilter 2) In some cases, sieve fails to correctly file based on this header 3) Testing with sieve-test indicates that it's testing the wrong header 4) Suggestions? Am I doing something wrong? Is there a problem with these headers that bends test-sieve out of shape? 5) Test files from below are also available via http://www.swynwyr.com/sieve-test/ Any help is appreciated!!! Long version with full details: Here is the simple sieve filter I'm using to test, and two different variants of an email which triggers this problem. I basically deleted things one by one from an original email (1) to get minimal testcases that triggered (2) or did not trigger (3) the problem. The filter: === begin test.sieve === require ["fileinto", "body", "regex"]; if header :contains "X-Bogosity" "Spam," { fileinto "SPAM.SPAM"; stop; } elsif header :contains "X-Bogosity" "Unsure," { fileinto "SPAM.UNSURE"; stop; } keep; stop; === end test.sieve === Here is an example email that will cause this filter to not function as expected: === begin message.2 === Return-Path: <alora(a)promosforusio.org> Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.2 === If I run test-sieve on this, we can clearly see in the trace log that when it's supposed to test for header "X-Bogosity" it in fact looks at one of the multiple "Subject" headers. Note that the result is storing in INBOX rather than SPAM.SPAM, and that the "matching value" for "X-Bogosity headers" is actually the contents of the final "Subject" header in the test on line 3. In the second test, on line 6, it uses a different and correct value for the same header! But too late to help as the first test was the one it should have had a match on. === begin session === $ sieve-test -t trace2.log -Tlevel=matching test.sieve message.2 Performed actions: * store message in folder: INBOX Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace2.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `AHS Kitchen Makeover Giveaway' 3: with key `Spam,' => 0 3: finishing match with result: not matched 3: jump if result is false 3: jumping to line 6 6: header test 6: starting `:contains' match with `i;ascii-casemap' comparator: 6: extracting `X-Bogosity' headers from message 6: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 6: with key `Unsure,' => 0 6: finishing match with result: not matched 6: jump if result is false 6: jumping to line 11 11: keep action; store message in default mailbox 12: stop command; end all script execution ## Finished executing script 'test' $ === end session === Now lets remove the "Return-Path" from that message. (Of the original 26 headers, all but the 7 shown in message.2 could be removed and still have this message break the filter). This alters thing enough that sieve starts working as expected (in fact, removing any one of the 6 non-X-Bogosity headers will cause this to start working). === begin message.3 === Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.3 === Now when we run test-sieve it works as expected, filing into SPAM.SPAM and showing the correct matching value for line 3: === begin session === $ sieve-test -t trace3.log -Tlevel=matching test.sieve message.3 Performed actions: * store message in folder: SPAM.SPAM Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace3.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 3: with key `Spam,' => 1 3: finishing match with result: matched 3: jump if result is false 3: not jumping 4: fileinto action 4: store message in mailbox `SPAM.SPAM' 5: stop command; end all script execution ## Finished executing script 'test' $ === end session ===

mailbox in different filesystem
by Héctor Moreno Blanco 08 Oct '14

Hello everyone, We have Dovecot 2.1.6 with Maildir. We would like to perform some kind of mail archiving with a mailbox in a different storage, for example a mailbox called ARCHIVED, with different disks (slower...). Is possible to locate this mailbox in other storage (SAS, Fiber...) and how can we do it? Thank you very much in advanced. Kind regards.

dovecot 2.1 new imap folder permissions
by Stefanos Gerangelos 07 Oct '14

07 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I hope this is the appropriate place to ask. I am migrating an old mail (postfix/dovecot) server to a new one. Everything works much as expected. I have a small obstacle though. I use mbox format and the setup is pretty much simple. Suppose a user's home directory is the following: # ls -ld /home/foo drwxr-xr-x 3 foo users 4096 Oct 4 13:28 foo and the respective /var/mail: # ls -ld /var/mail/foo - -rw------- 1 foo mail 0 Oct 4 23:45 /var/mail/foo In the old server when the user tried to create a new test imap folder (from an imap client), then the newly created file would be: # ls -l /home/foo/ - -rw------- 1 foo users 0 Oct 2 02:08 test This is the desired behavior. In the new dovecot 2.1 server the following file permissions will apply: # ls -l /home/foo/ - -rw-r--r-- 1 foo users 0 Oct 2 02:08 test I finally noticed that if I chmod the /home/foo to 711, then the new file will have the desired (600) permissions. So, I can make a umask for the new users (login.defs), but that doesn't sound a pretty solution. Do you have anything else to suggest? If you need any .conf file, let me know.

Dovecot writing to mailbox user@domain
by John Oliver 06 Oct '14

centOS 6.5, dovecot-2.0.9-7.el6_5.1.x86_64 This is frustrating, because I had it working before... I could deliver an email to a user user@domain, then connect to dovecot IMAP and see the mail, no problem! Then I was told we had to use cyrus, and I was dealing with it for a few weeks. Now we're back to dovecot, and the last backup I had of that config has postfix delivering mail to /var/vmail/username as I want and expect, but dovecot looks for and creates /var/vmail/user@domain which I DON'T want [joliver@test ~]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_username_format = %Lu mail_access_groups = mail mail_location = maildir:/var/vmail/%u/Maildir mail_privileged_group = mail mbox_write_locks = fcntl passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } userdb { args = uid=504 gid=505 home=/var/vmail/%u driver = static } [joliver@test ~]$ cat /etc/dovecot/dovecot-ldap.conf.ext hosts = localhost auth_bind = no ldap_version = 3 debug_level = 0 default_pass_scheme = SSHA base = ou=Users,dc=test,dc=com scope = subtree pass_filter = (&(objectClass=user)(uid=%u)) pass_attrs = mail=user,userPassword=password -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

How best to confirm that dovecot LDA logging is working correctly?
by Ben Johnson 06 Oct '14

06 Oct '14

Hello! I've posted to the list several times about a strange issue I'm having with dovecot LDA. When dovecot-lda is called in the context of a pipe script that is executed as the "vmail" user via the Dovecot Antispam plugin, dovecot-lda exits prematurely with status code 134. The dovecot deliver manual at http://wiki2.dovecot.org/LDA#logging states very clearly, "If dovecot-lda fails to write to log files it exits with temporary failure." That's a curious note, because I believe that a "temporary failure" exit code may be what I'm dealing with here. When I drag an email from Inbox to SPAM to trigger Antispam, I see only this (and no further output beyond the last line) in syslog, which is the configured logging destination for LDA: imap: antispam: mailbox_is_unsure(Junk): 0 imap: antispam: mailbox_is_trash(INBOX): 0 imap: antispam: mailbox_is_trash(Junk): 0 imap: antispam: mail copy: from trash: 0, to trash: 0 imap: antispam: mailbox_is_spam(INBOX): 0 imap: antispam: mailbox_is_spam(Junk): 1 imap: antispam: mailbox_is_unsure(INBOX): 0 imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh imap: antispam: running mailtrain backend program parameter 2 --spam By contrast, if I "su" to the "vmail" user and call the LDA executable with the same arguments that my pipe script does, I see all of the expected output in syslog, AND the message is delivered successfully: /usr/lib/dovecot/deliver -d "sa-training(a)localhost.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-25169.txt" lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so lda: Debug: auth input: sa-training(a)localhost.com home=/var/vmail/localhost.com/sa-training mail=maildir:/var/vmail/localhost.com/sa-training/Maildir uid=5000 gid=5000 quota_rule=*:storage=0B sieve=/var/vmail/localhost.com/sa-training/.sieve lda: Debug: Added userdb setting: mail=maildir:/var/vmail/localhost.com/sa-training/Maildir lda: Debug: Added userdb setting: plugin/quota_rule=*:storage=0B lda: Debug: Added userdb setting: plugin/sieve=/var/vmail/localhost.com/sa-training/.sieve lda(sa-training(a)localhost.com): Debug: Effective uid=5000, gid=5000, home=/var/vmail/localhost.com/sa-training lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail/localhost.com/sa-training/.quotausage lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=* bytes=0 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Trash bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Junk ignored lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=INBOX bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=sa-training(a)localhost.com, uri=file:/var/vmail/localhost.com/sa-training/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: maildir++: root=/var/vmail/localhost.com/sa-training/Maildir, index=, indexpvt=, control=, inbox=/var/vmail/localhost.com/sa-training/Maildir, alt= lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail//raw mail user/.quotausage lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below raw mail user lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=raw mail user, uri=file:/var/vmail//raw mail user/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= lda(sa-training(a)localhost.com): Debug: Destination address: sa-training(a)localhost.com (source: user@hostname) lda(sa-training(a)localhost.com): Debug: sieve: Pigeonhole version 0.4.2 initializing lda(sa-training(a)localhost.com): Debug: sieve: include: sieve_global_dir is not set;

the implication seems to be that dovecot-lda is crashes immediately, before it can log anything, when it's triggered via Antispam. Is there some way to determine what's happening? I've posted coredump and trace information previously, and nobody replied. Thanks for any help! -Ben

Hi dovecot guru.. I need some help configuring shared folder in my server.. This is the situation: DOVECOT 2.0.19 with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN This is the production server and sharing folder between user work.. But i need some explanation.. 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without share the main folder .INBOX? 2) Which is the best way (or best practice) to manage the dovecot-acl and dovecot-acl-list file?? Actually, i modifiy the dovecot-acl by hand (vi editor). but every time i modify it i need to restart the dovecot server to apply the configuration. And i need to reset the /var/run/dovecot/dict owner and group cause with dovecot restart the file go back in root:root owner - group Thank's in advance. Gianluca

v2.2.14.rc1 released
by Timo Sirainen 06 Oct '14

06 Oct '14

http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz.sig I've wanted to do this release for months now, but I keep being too busy all the time. This release fixes several important bugs and a lot of smaller ones. Because there are such a large number of changes I thought I'd make this release candidate release first and the final v2.2.14 early next week. I usually read through the Dovecot mailing list mails before making a new release to see if there are some (important) bugs reported, but I've been way too busy recently to read through everything. I still have over 250 unread mails and I don't think I'll have time to read them anytime soon. On the positive side the Dovecot company is now hiring more people. Especially having more Dovecot coders would reduce my work load and maybe allow me to go back to reading the Dovecot mailing list daily.. See: http://www.dovecot.fi/dovecot-is-hiring-software-engineer-helsinki/ (you can do this work anywhere - no need to live in Finland) http://www.dovecot.fi/dovecot-is-hiring-operations-and-support-engineer-hel… (this probably requires living in Finland) http://www.dovecot.fi/dovecot-is-hiring-technical-pre-sales-engineer-helsin… (probably no need to live in Finland) Here are some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

X-sieve-redirected-from
by Bob Miller 05 Oct '14

Hi, I am chasing a problem with sieve vacation messages. the sieve file looks like this: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["copy","vacation"]; # rule:[computerisms.ca] if anyof (address :contains "To" "bob.miller(a)ctfn.ca", address :contains "Cc" "bob.miller(a)ctfn.ca") { redirect :copy "bob(a)computerisms.ca"; vacation :days 66 :subject "autotest" "hello back"; } The mail is forwarded, but no vacation response is sent, and the mail is not forwarded. I find the lda error like this: _discarding_vacation_response_for_implicitly_delivered_message; _no_known_(envelope)_recipient_address_found_in_message_headers_ (recipient=<bob.miller(a)hostname.domain.tld>,_and_no_additional_ `:addresses'_are_specified) I am presuming this is the source of my problem. I am not sure why the domain is being modified to reflect the fqdn of the mail server host. When I look at the delivered mail, I find the following two headers: X-sieve-redirected-from: bob.miller(a)hostname.domain.tld Delivered-to: bob.miller(a)domain.tld I have been looking for a while now, and I can't figure out where it is picking up the hostname from. doveconf -a | grep hostname comes up empty. the hostname is not in any of the mta config files. Anyone got a hint? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot does not update maildirsize after expunge
by Király Balázs 04 Oct '14

Hello, At the first, sorry for my englishJ I have a problem with dovecot quota since i migrated from courier. Dovecot does not update the Maildirsize after expunge, and the user running out of his quota very quickly. I checked, the file is deleted from the filesystem. If i delete the Maildirsize file, dovecot regenerate it with the correct datas when a new mail arrive. Also tried to set mail_debug=yes, but it doesnt show anything in the log, when delete mails. Im using NFS as homedirs, i tried to turn off the releated options in configuration, but didnt help. Has anyone any idea how to fix this issue? Thank you!

Configure antispam plugin with private namespaces

When I use antispam plugin <http://wiki2.dovecot.org/Plugins/Antispam> with a folder that is outside a namespace, the plugin works great.

Thunderbird ignores some folders
by dovecot.pkoch＠dfgh.net 03 Oct '14

03 Oct '14

Dear readers we are using Dovecot 2.2.7 and all of our users are using Thunderbird as their mail client. Some of them additionally use their iPad/iPhone and a very few an Android Mail-Client. Now one user noticed that two of his mail folders disappeared. He first believed that he accidentally deleted those folders but then he realized that they are still visible from his iPad. I checked this users maildir and everything looks normal. Deleting the index-files made no difference: New index-files were created but those two folders are still invisable from Thunderbird. My main concern is to find the reason for this behaviour. Maybe folders of other users have disappeared and they have not yet noticed. A fresh installation of Thunderbird will most likely fix this single users problem, but I cannot do this for all of our users. So here's my question: How would I debug such a situation? Kind regards Peter Koch And here's our config file: # Dovecot configuration file default_process_limit = 2048 protocols = imap listen = * base_dir = /var/dovecot/ mail_location = maildir:/mail/%u:LAYOUT=fs ssl_cert = </etc/ssl/certs/naev+chain.crt ssl_key = </etc/ssl/private/naev.key ssl_ca = </etc/ssl/certs/naev-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier auth_ssl_username_from_cert = yes service imap-login { inet_listener imap { port = 0 } } service auth { client_limit = 4096 } service anvil { client_limit = 5000 } passdb { driver = checkpassword args = /usr/dovecot/bin/checkpassword } userdb { driver = passwd override_fields = home=/mail/%u } protocol imap { mail_max_userip_connections = 1000 }

LDA randomly failing to write email to disk
by Andy Dills 03 Oct '14

03 Oct '14

We're using 2.2.13 with pigeonhole 0.4.3, in a clustered environment (maildir on netapp, dual dovecot instances where each server is both a proxy and a backend). Every now and then (once a month per user, maybe?), users will see a blank email in their inbox. Investigating further, and we will see that the only information recorded in the maildir file for the message is the Return-Path, the Delivered-To, and the first Received line (the one generated by the local LDA via LMTP). For example, here is what I found in one such email today: Return-Path: <xxx(a)xecu.net> Delivered-To: <yyy(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail2.xecu.net (Dovecot) with LMTP idX86eBjgaI1RdyQAA3SxDBg for <yyy(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Everything past that is lost, as if the either the LDA on mail2 exited early or was never sent the information from the dovecot instance on mail5. Here is a little more detail from the header of the same email, different recipient (all other recipients received the email properly, only one failed to receive properly): Return-Path: <xxx(a)xecu.net> Delivered-To: <yyz(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail1.xecu.net (Dovecot) with LMTP id KPh8ItMXI1StBAAA/c3zFg for <yyz(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net by mail5.xecu.net (Dovecot) with LMTP id QsUBFoQZI1RjhgAAXyr1JQ ; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net (localhost [127.0.0.1]) by mail5.xecu.net (Postfix) with ESMTP id 30AAE323BB18; Wed, 24 Sep 2014 15:24:20 -0400 (EDT) ... This is what I see in the logs of mail2, which is where the failure happened: Sep 24 15:24:20 mail2 dovecot: lmtp(51549, yyy(a)xecu.net) X86eBjgaI1RdyQAA3SxDBg: sieve: msgid=unspecified: stored mail into mailbox 'INBOX' When I look at the logs of mail1, which is where the successful delivery happened: Sep 24 15:24:20 mail1 dovecot: lmtp(1197, yyz(a)xecu.net) KPh8ItMXI1StBAAA/c3zFg: sieve: msgid=<20140924192412.1435.qmail(a)xxx.xecu.net>: stored mail into mailbox 'INBOX' Nothing of note seems to be logged on mail5 (only a message from postfix, nothing from the proxy side of the lmtp). I do notice, when I check for the PID of 51549 in the logs, all of its other transactions seem to register with proper msgids and were delivered fine. Also, I notice plenty of other messages that have the msgid=unspecified error, but which were delivered with no problems and not truncated, so I'm suspecting what may be happening is that somehow the backend instance is not receiving the actual data portion, and only getting the envelope from proxy instance. How do I approach debugging this? It's very infrequent, but yet quite annoying. Seems to have started since we upgraded to 2.2.13 (from an older 2.1 build) earlier this year. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

GETMETADATA UTF8 encoding of folder names instead of UTF7

home from SQL
by Ralf Hildebrandt 03 Oct '14

03 Oct '14

Currently I'm using user_query = SELECT 1000 AS uid, 1000 AS gid, '/srv/vmail/%2.256Hu/%Lu' AS home, ... so I'm hashing based on %u (basically). But in my SQL db I have a "unique_identifier" field, which never changes, even when the user is changing his/her email address (due to marriage or the like). What I'd really like to do is to use %u to find the value of the unique_identifier field, hash THAT value and use "AS home". But how? That way I can rename users without shuffling directories around the filesystem. -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Re: [Dovecot] quota using wrong limits in user shared mailboxes
by Bartłomiej Nogaś 03 Oct '14

03 Oct '14

Hi, I confirm this bug with LDAP userdb. The temporary workaround is to set quota ignore rule for Shared namespace or specific shared folder. This is obviously not secure workaround. Example: for a shared namespace: namespace ( .... prefix = Shared Folders/%%u/ ... } you have to set quota_rule4 = Shared Folders/*:ignore or quota_rule4 = Shared Folders/username/*:ignore - Bartlomiej Nogas

Trouble getting listescape plugin to work with "$" separator (as demonstrated in Wiki) in Dovecot 2.2.9
by Ben Johnson 03 Oct '14

03 Oct '14

Hello, I'm attempting to install the listescape plugin so that IMAP users are able to include periods (.) and forward slashes (/) in IMAP directory names. I'm following the instructions at http://wiki2.dovecot.org/Plugins/Listescape , which imply that this can be accomplished by enabling the listescape plugin and using the dollar sign ($) as the separator. With regard to my dovecot configuration, first, I changed protocol imap { mail_plugins = quota imap_quota antispam } to protocol imap { mail_plugins = quota imap_quota antispam listescape namespace private { separator = $ inbox = yes } } When I start dovecot, I receive the following error: doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:102: namespace private {} has been replaced by namespace { type=private } Pretty straightforward; I made the required change to yield protocol imap { mail_plugins = quota imap_quota antispam listescape namespace { type = private separator = $ inbox = yes } } But now, when I attempt to start dovecot, I receive the following error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ Is it possible that the instructions at the Wiki 2 URL cited above are out-of-date? If I try to escape the $ with any other character (I'm just shooting in the dark regarding possible escape characters, as I cannot find definitive documentation that pertains to escaping $ in the dovecot configuration), I receive yet another error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long Ultimately, I have two questions: 1.) Is the nesting structure that I've employed correct?

auth with entire email addr instead of just username
by Cliff Hayes 03 Oct '14

03 Oct '14

I am trying to configure a new IMAP based mail server. I thought I had everything correct. I have dovecot logging turned up and see that dovecot is processing the entire email address as the username like this... Oct 2 14:52:20 servername dovecot: auth: Debug: pam(testuser(a)domain.com,1.2.3.4): lookup service=dovecot ... and of course pam is reporting that as an invalid user. Moments ago when all was mbox, authentication worked fine. I can see Thunderbird has the username correct (no domain). What is tacking on the domain and how do I fix? Thanks in advance.

two dovecot instances
by jjhoffart 02 Oct '14

02 Oct '14

Hello, I am currently trying to setup two invocations of dovecot to run on a debian based server. One for director and the other a stock debian instance. The issue I am having is when I go to start the director instance, I receive multiple errors telling me that the listening ports are already in use. I have change these ports in the 10-master.conf file but am still presented with the same errors when starting the second instance. Is this the only file in which the ports need to be changed (10-master.conf) or is there another file in which the ports need to be set?

Simply mysql quota check
by Alfredo Saldanha 02 Oct '14

02 Oct '14

Hi there, I'm setting up a new email server with Dovecot(2.2.9) and MySQL. My Dovecot configuration: #/etc/dovecot/conf.d/90-quota.conf service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = dovecot unix_listener quota-warning { user = vmail } } plugin { quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u@%d quota_warning2 = storage=80%% quota-warning 80 %u@%d args = /etc/dovecot/dovecot-sql.conf.ext } #/etc/dovecot/dovecot-sql.conf.ext password_query = \ SELECT username AS user, value AS password \ FROM mailboxes WHERE username = '%n@%d' user_query = \ SELECT username, domain, \ CONCAT('*:storage=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule \ FROM mailboxes, domains WHERE mailboxes.username = '%n@%d' \ AND domains.domain = '%d' My idea is when a message is delivered, the dovecot to check quota in the mysql according to the value received in the "user_query" but he does not. It shows a value of 2GB that I don't know where it gets. I execute a manual query in mysql to know the quota my test user and checked that are 5GB, but when I see the dovecot, it shows 2G. SELECT username, domain, CONCAT('*:bytes=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule FROM mailboxes, domains WHERE mailboxes.username = 'junix(a)domain.com' AND domains.domain = 'domain.com' +-------------------+----------------+--------------------+ | username | domain | userdb_quota_rule | +-------------------+----------------+--------------------+ | junix(a)domain.com | domain.com | *:bytes=5242880000 | +-------------------+----------------+--------------------+ $ sudo doveadm quota get -u junix Quota name Type Value Limit % User quota STORAGE 10 2097152 0 User quota MESSAGE 1 - How would the setting to simply verify the quota of users as userdb_quota_rule this query?

Master user and invalid credentials dovecot-2.2.13
by Götz Reinicke - IT Koordinator 30 Sep '14

30 Sep '14

Hi, I followed the docs from the dovecot wiki (http://wiki2.dovecot.org/Authentication/MasterUsers) and still have some problem: 1. uncommented "!include auth-ldap.conf.ext" in 10-auth.conf 2. htpasswd -b -c -s .... to create user/password for a masteruseruser 3. checked auth-master.conf.ext When I try to test the login, I always get an "invalid credentials" in the logs with auth_debug=yes set. dovecot can read /etc/dovecot/master-users The users are in ldap. The example wiki shows the passwords {SHA1}...., in my password file they are {SHA}.... The "master user" posting in september gave some clues what might be wrong, but did not help to solve my problem. Any suggestions are welcome! Thanks and regards.

No AUTH PLAIN with dovecot 2.0.19
by Michael Wechner 30 Sep '14

30 Sep '14

Hi I have installed the package dovecot-postfix on Ubuntu 12.04 LTS: dovecot --version: 2.0.19 postconf -d | grep version: 2.9.6 and receiving email works very fine, but relaying email does not work. I think the problem is that after STARTTLS the authentication is not being executed 250-AUTH PLAIN 250-AUTH=PLAIN which means using telnet returns telnet mx2.wyona.com 587 Trying 50.116.54.197... Connected to node3.wyona.com. Escape character is '^]'. 220 node3.members.linode.com ESMTP Postfix (Ubuntu) EHLO letscallitevil.com 250-node3.members.linode.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So far I have used dovecot version 1.2.9, which works very fine, but the configuration /etc/dovecot/dovecot.conf seems to be very different in the case of dovecot version 2.0.19. I have checked all kind of tutorials for several days now, like for example https://help.ubuntu.com/10.04/serverguide/postfix.html but nothing helped. Any pointers or help is very much appreciated. Thanks Michael

"doveadm sync/backup" and SSH should use "ssh-agent" if available
by Jesus Cea 30 Sep '14

I use SSH-AGENT in my system, to cache SSH credentials and avoid typing my key every time I connect to a remoto host.

"doveadm backup/sync" are badly documented
by Jesus Cea 29 Sep '14

29 Sep '14

Most documents around there talk abour "dsync", but the modern way is "doveadm backup". This command is not documented in the wiki and there are a few details missing, like how to use it thru SSH. I am currently doing some tests about how to backup my mdbox. I can do tests in local using: $ doveadm backup -u jcea -m proveedores/dovecot mdbox:/tmp/aa/ This will "backup" this mailing list mailbox to "/tmp/aa". Good. Lets try thru SSH: $ doveadm backup -u jcea -m proveedores/dovecot ssh 127.0.0.1 dsync -u jcea mdbox:/tmp/aa/ jcea(a)127.0.0.1's password: Fatal: Invalid parameter: mdbox:/tmp/aa/ dsync-local(jcea): Error: read(remote) failed: EOF (version not received) How shoudl I do it?. $ doveadm backup -h backup: invalid option -- 'h' doveadm backup [-u <user>|-A] [-S <socket_path>] [-dfR] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] <dest> I can't find any explanation at all about the different parameters of "doveadm backup".

"doveadm backup/sync" don't follow message moving even with MDBOX
by Jesus Cea 29 Sep '14

29 Sep '14

Using mdbox as the storage backend, moving a message from a mailbox to another just update a reference. The message is not fisically moved on the disk. I would expect "dsync" to use this fact when source and destination are mdbox. But it doesn't. Anybody else can confirm?. Any plan to implement it?. Thanks!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

dsync full sync
by Atıf CEYLAN 29 Sep '14

29 Sep '14

Hi all, I have 2 question. First: I use dovecot (version 2.2.9) with mdbox mail format. When I run dsync tool with "mirror" or "backup" parameters my source and destination directory synchronize correctly but if I delete some messages in user mailbox, deleted messages does not synced to destination. For example : atif(a)domain.com path is /mail/domain.com/atif/ and its size is 1GB. after first running the "dsync -u atif(a)domain.com backup mdbox:/backup/domain.com/atif/" command, size of "/backup/domain.com/atif/" is 1GB I deleted 300mb messages in atif mailbox then /mail/domain.com/atif/ is decreased to 700MB and I launched dsync command again. But /backup/domain.com/atif/ is not decreased to 700Mb. My backup directory still 1GB . I tried dsync with "-f , backup, mirror" parameters. Second problem, the first time the backup atif's quota size is increasing to x2. before backup : atif(a)domain.com quota size 1GB after backup: atif(a)domain.com quota size 2GB so I must run "doveadm quota recalc" command. Why? What is correct usage of mdbox mail format and dsync tool? -- M.Atıf CEYLAN

dsync mirror does not maintain changes between mailboxes
by Alan McGinlay 28 Sep '14

28 Sep '14

Hi, running: dsync -D -v -o mail_fsync=never mirror -R -f -u user@domain imapc: Where "domain" is a cyrus imap server does not do what the documentation says it does, not even close. After the first run to an empty mailbox on the dovecot 2.2.13 server all the mails (1.1GB) seem to be correctly synced. I send a test email to the dovecot server and it shows up correctly. Second run of the above dsync command, first thing that happens is all mails are deleted from the dovecot mailbox (yet the storage used by output of "du -m" doesn't change) and the sync appears to happen again from scratch however the disk space increases again! Now up to about 2GB and another run will take it up a few hundred mb more! I have tried with multiple different mail storage formats, maildir++, mdbox sdbox, all show the same (except maildir which just complains that INBOX can't be deleted on the second dsync run). This is frustrating beyond belief, please please anyone who has any insight let me know, the dsync debug output is a little huge to sanitize and post to the list but i can send it individually if anyone has any ideas! I am ready to give up totally on dovecot but at the same time I just wish it would work! doveconf -n # 2.2.13 (6bb26098a45c): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-67-virtual x86_64 Ubuntu 14.04.1 LTS auth_debug = yes auth_master_user_separator = * default_vsz_limit = 512 M disable_plaintext_auth = yes imapc_features = rfc822.size imapc_host = oldmailhost.domain.com imapc_master_user = cyradmin imapc_password = xxxxxxxx imapc_user = %u mail_gid = vmail mail_home = /var/vmail/domains/%d/%1n/%n mail_location = sdbox:~/sdbox mail_plugins = zlib notify quota fts fts_solr mail_prefetch_count = 30 mail_uid = vmail mailbox_list_index = yes managesieve_sieve_capability = fileinto imapflags 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 = / } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ quota = dirsize:User quota quota_grace = 10%% quota_rule = *:storage=20G sieve = ~/.dovecot.sieve sieve_dir = /var/vmail/sieve/domain/%1d/%d/%1n/%n/ sieve_extensions = imapflags fileinto zlib_save = bz2 zlib_save_level = 5 } protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } vsz_limit = 512 M } service imap { process_limit = 1024 vsz_limit = 512 M } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = zlib notify quota fts fts_solr quota sieve } protocol imap { mail_plugins = zlib notify quota fts fts_solr imap_quota } protocol sieve { managesieve_implementation_string = Cyrus timsievd v2.2.13 }

Dovecot Sieve and Postfix header_checks Issue
by Klaipedaville on Google 27 Sep '14

27 Sep '14

Hello List, I tried to subscribe but it's taking forever for the confirmation email to arrive so I thought I would ask away by emailing directly. My apologies in advance should this question appear twice. It may seem real simple to experts but I cannot really figure it out. I'll try to be concise: Dovecot version is 2.1.7. Its dovecot –n is real short one and follows right after my question. I have my Postfix 2.9.6 properties set like this: header_checks = /etc/path/to/myfile. Then I have Dovecot Sieve also configured and working fine. Now the trouble is that these two cannot be combined together can they? Dovecot Sieve and Postfix's header_checks? If I turn off header_checks in Postfix then Dovecot Sieve is working fine. If I vise versa turn off Dovecot Sieve then Postfix's header-checks are also working fine. However, when I keep them both turned on it also works but only partially and in this case Dovecot Sieve never bounces back any rejected massages remotely, the bounce happens only locally. That is I can see it in my logs that it was rejected locally but the message is never sent back to the sender saying something like, "Spam is rejected here". Thus the reject turns into a silent discard without telling the sender anything at all. Any ideas, help, advices how do I fix that? Would be really grateful for any suggestions / assistance at all. Many thanks in advance! P.S. I would like to use both because Dovecot Sieve is a very powerful and great plugin that uses Spamassassin's added tags and headers based on which I create my rules. Postfix in its turn has a very neat feature of checking the headers via regexp but Postfix does not see / detect Spamassassin's added headers at all because I passed delivery and authentication (which is a way better than Postfix's) to dovecot deliver. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.6 ext4 auth_mechanisms = plain login cram-md5 scram-sha-1 auth_verbose = yes hostname = WindTalker info_log_path = /var/log/dovecot-sieve.log log_path = /var/log/dovecot-sieve-errors.log mail_location = maildir:/home/mvail/%d/%n 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 passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_default = /etc/dovecot/default.sieve sieve_dir = ~/sieve } pop3_uidl_format = %g postmaster_address = postmaster(a)example.com protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_ca = </etc/ssl/ca.crt ssl_cert = </etc/ssl//new.crt ssl_key = </etc/ssl/new.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { mail_debug = yes mail_plugins = sieve } Regards, Dennis.

ALT storage question

I want to migrate from a non-hashed storage to a hashed storage. So I set this up: mail_location = mdbox:/srv/vmail/%2.256Hu/%Lu/mdbox:ALT=/srv/vmail/%Ld/%Ln/mdbox I rsynced the "old" mdbox-style mailbox from another machine to to /srv/vmail/%Ld/%Ln/mdbox (/srv/vmail/charite.de/ralf.hildebrandt/mdbox in my case) The mail_location /srv/vmail/c5/ralf.hildebrandt(a)charite.de was non-existing.

Thanks for confirming what I suspected, Timo. The latter, if it is at all feasible, appears to be an "inside job" type of exploit, where the exploiter already has an account but can arbitrarily change their password. It's not as serious as the pre-login one, but worth addressing if the narrow circumstances of using post-login bash scripts apply. Joseph Tam <jtam.home(a)gmail.com>

Re: director
by Chris Lasater 26 Sep '14

26 Sep '14

The configuration and run/base_dir directories can be where ever you like. The locations Eduardo stated are the most appropriate for dovecot installed with an RPM. Mine were compiled and set in the home directory, so they are in a slightly different location. As long as you use the -c to point to the correct configuration file you should be good. For mine I kept my dovecot config file in the default location and put the director one elsewhere and created an alias, so that I can start the director by just typing director. This might make things easier for you to manage, then you can just stop it by running "doveadm -i <instance_name> stop" alias director="sudo -E PATH=${PATH} LD_LIBRARY_PATH=${LD_LIBRARY_PATH} /home/user/dovecot/sbin/dovecot -c /home/user/dovecot/etc/dovecot/director.conf" On 09/23/2014 05:00 PM, jjhoffart wrote: >> Thanks for the replies, >> I am still fairly new to dovecot and still learning.

Is dovecot vulnerable to the shellshock/CVE-2014-6271 exploit?
by Joseph Tam 26 Sep '14

26 Sep '14

I'm right now handling this beach-ball sized grenade, and trying to figure out which of our services need to be locked down right away. Since dovecot passes values via environment variables based on user input (e.g. username, password, mailbox?) to auxilliary executables (including possibly bash shell scripts), is dovecot vulnerable to this exploit? (This is not a fault of dovecot, but rather bash's inadequate handling of environment variables.) For example, injection of this sort 1 LOGIN (){x;}exploit-code whatever I guess auth_username_chars would mitigate this particular attempt (assuming it can work), but other values such as mailbox names could also be injected post authentication. Can someone with working knowlegde of dovecot's internals confirm/deny whether this is a something that needs to be addressed? Joseph Tam <jtam.home(a)gmail.com>

How to configure dovecot imap to listen on multiple ports?
by Rick Thomas 26 Sep '14

26 Sep '14

I need my dovecot imap server to listen on ports 143, 993, and also 30143 and 30993. What syntax do I use in (I presume) the /etc/dovecot/conf.d/10-master.conf file to do this? Thanks! Rick

Does dovecot work OK on *BSD?
by Steve Litt 26 Sep '14

26 Sep '14

Hi all, I have a dovecot server on my Debian Wheezy desktop computer. My days with Debian are limited, and I'm investigating several 'BSD's: OpenBSD FreeBSD PCBSD NetBSD DragonflyBSD etc Is there any reason Dovecot wouldn't work on any of those? Does anyone know if those OS's have packages for Dovecot, or do I need to compile it myself? Thanks, SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Confusing wording on the wiki
by Alan McGinlay 24 Sep '14

24 Sep '14

Hi, I am confused by the wording of this Wiki entry: sieve = ~/.dovecot.sieve The path to the user's main active Sieve script. When ManageSieve is used, this is a symbolic link pointing to the active script in the sieve_dir directory. Avoid placing the active Sieve script inside the sieve_dir directory. So this should be a link *to* the active script in the sieve_dir directory however the active script shouldn't actually be in that directory???? http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration Confused :S /A

Empty mailboxes
by Daniel Miller 24 Sep '14

24 Sep '14

This is driving me nuts. I need to rebuild a server - got a notification the main drive is failing, and it's been a year or two, so it's time. Got a new drive, fresh install of Ubuntu Tantric, started installing everything needed. Data stored on a RAID array - nicely available separate from the boot/operation drive. Did a fresh compile of Dovecot, copied over the configs from the old drive, mounted the RAID...and... Dovecot starts, authenticates users - and shows empty mailboxes. Nothing shown. Full panic - reboot on old drive. All mails present. Change back - no mail. Executing "doveadm user -u username" seems to give valid results. Mailbox location appears correct (using mdbox). I setup uid/gid the same - I thought it was a rights issue but everything looks correct. What can I do to try to find the stupid mistake I'm making? -- Daniel

quota recalc problem for big maildirs
by Dawid Stawiarski - nazwa.pl 24 Sep '14

24 Sep '14

hi, we use dovecot 2.2.13, and we've lately started using maildir quota (previously fs quota was used, right now it's "quota = maildir:User quota" changed from "quota = fs:User quota:user:inode_per_mail"). When the change was applied we didn't manually forced generating maildirsize files. So, when the first deliver happens (or the file grows larger then 5KB) it starts quota recalc. However for users with big maildirs, receiving email every couple of seconds, there are tens of delivery processes each doing its own recalc (as they open file for APPEND and there's no locking). What's even worse, after all the stats and getdents (it takes a lot of IO for 60GB account with 2M emails), deliver makes stat on 'new' dir and detects changes after which it unlinks freshly created maildirsize. So possibly this will never be finished as every process drops its own work. The same thing happened when we checked the native dovecot LMTP server (every connection has its own forked process - each running independently of the others). Is it a known unwanted "feature" of maildir quota (and we should use dict quota instead) or a bug that will be fixed? cheers, Dawid Stawiarski

Re: director
by Eduardo Ramos 23 Sep '14

23 Sep '14

The configuration use to be in /etc/dovecot, and the working dir is /var/run/dovecot. You should store your configuration file in the /etc/dovecot. The dovecot.conf file can be copied to dovecot-backend.conf and dovecot-director, for example, and you will use '-c' argument of dovecot binary to load on or another. If you do this, you will need create two separated working dir, that will be defined in base_dir on each configuration file.

This is a quick run down of my setup: 3 servers running iRedMail (this is a package that installs dovecot 2.1.7, postfix, and LDAP). All three servers share an NFS backend. The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot.

Hello, I'm aware of these two threads http://www.dovecot.org/pipermail/dovecot/2012-March/thread.html#134311 http://dovecot.org/pipermail/dovecot/2012-June/thread.html#136488 but unfortunately I wasn't successful with my dsync mailbox migration attempt despite the information I could find there. I'm using iRedMail setup for the dovecot server. I made sure that the dovecot mailbox for the mail import had been freshly created and untouched before I tried to run the following command. Running this command: sudo doveadm -vvv -o imapc_host=s04.srv-net.de -o imapc_user=username -o imapc_password=password -o mail_fsync=never -o mail_prefetch_count=20 -o imapc_features=rfc822.size -o

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 23 Sep '14

23 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Announce: Plugin for iOS Push Email support
by Stefan Arentz 23 Sep '14

23 Sep '14

I’ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple’s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.

> BTW: It would be nice, if I could just 'git clone' dovecot. Hi, Thomas, I happily use Felipe Contreras' excellent git-hg bridge, as I am far happier in a GIT environment than an Hg one: https://github.com/felipec/git/wiki/git-remote-hg The workflow couldn't be much easier, in particular if you set up a few aliases for the common sequences of tasks. $ hg clone http://hg.dovecot.org/dovecot-2.2 $ git clone "hg::/home/phil/dovecot-2.2" dovecot-2.2-git $ cd dovecot-2.2-git $ git checkout -b hacking $ # work... $ cd ../dovecot-2.2 $ hg pull -u $ cd ../dovecot-2.2-git $ git checkout master $ git rebase master hacking $ # more work... (OK, my workflow includes pushing too ;-) ) Hope that helps. Cheers, Phil

dsync annoyances
by Alan McGinlay 23 Sep '14

23 Sep '14

Hi! Every time I run dsync for a user against an old Cyrus server, the users mailbox in Dovecot increases by several hundred MB, these are not new emails. So the first dsync run gets the whole mailbox and subsequent runs get a bunch of duplicates or what? doveadm purge clears them all out but why is dsync behaving like this? I didn't happen in previous versions (2.2.13)

Hi, I'm writing a test suite with Haskell for my sieve script. - Just to learn Haskell. But it might become something usable. The test suite calls sieve-test and parses the output. So it would of course be much simpler for me if the output of sieve-test would be easier to parse and if I'd know what output to expect. And it would be nice, if there would be an easy way to embed libsievetest as a C library. I looked into the source and the sieve-test binary does quite a bit of setup. This might be a nice hacking project for a beginner... BTW: It would be nice, if I could just 'git clone' dovecot. Thank you for dovecot!

doveadm with multiple instances on same machine(s)
by Will Yardley 22 Sep '14

22 Sep '14

Couple questions about running doveadm with multiple instances... I have Dovecot 2.2.13 on RHEL6 running across 3 boxes, each with a director and main instance running. When I try to lookup something on the main instance (which is handling user auth) via its auth-userdb socket directly, I get an error: # doveadm auth lookup -a /var/run/dovecot-main/auth-userdb myuser doveadm(root): Error: passdb lookup failed for myuser: Configured passdbs don't support crentials lookups When I use the default lookup map, I just get the proxy settings that are configured in the director instance's authdb. # doveadm auth lookup myuser passdb: myuser user : myuser proxy : y nopassword: y In addition, "doveadm director map" can't map the username -I get the error: doveadm(root): Error: User listing returned failure doveadm(root): Error: user listing failed [then I get the whole list, but with <unknown> for each user] The director itself doesn't have the LDAP passdb that the main dovecot instance talks to, but I have, in the director config: service doveadm { inet_listener { port = 8889 } } director_doveadm_port = 8889 local 192.168.x.x/24 { doveadm_password = XXXXXX } doveadm_proxy_port = 8888 And in the main config: service doveadm { inet_listener { port = 8888 } } local 192.168.x.x/24 { doveadm_password = XXXXXXX ## same password as above }

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 22 Sep '14

22 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Authentication using AD : bug ?
by Nicolas Cauchie 22 Sep '14

22 Sep '14

Hello, I've setup a mail server (still in test) with Postfix and Dovecot, authentication made using Active Directory. I authenticate my test user in AD well in Dovecot. However, if I change this user's password in AD, the old password still works for authentication in Dovecot and the new is working too. Is there a time to make Dovecot don't "remember" the old password or is it a bug ? Restarting Dovecot don't solve the problem. Do you already heard about this ? Please tell me what conf files you maybe need. Thanks in advance Nicolas signature -----

Re: LDAP and dovecot
by dovecot＠outputservices.com 22 Sep '14

22 Sep '14

For the record. I compiled dovecot to use the openldap libraries my openldap server uses. My email server and ldap server are on two different machines. So I just copied over my ldap libraries and placed them in the correct place and then compiled dovecot. I saw this clue in a different web page. Something about Solaris ldap libraries being bad. CPPFLAGS=-I/usr/local/openldap/include \ > LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This now allows me to authenticate with my openldap server. I am NOW able to authenticate to my ldap server. So my final configuration is: dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } /dovecot/etc/dovecot/conf.d/ldap.settings hosts = ldap.outputservices.com tls = no auth_bind = yes ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com Thank you all.

X-DOVECOT capabilities
by Timo Sirainen 22 Sep '14

22 Sep '14

Dovecot has a few hidden features currenly, which I know some webmails have been hardcoded to use. Maybe it would be nice to have these available in a bit more globally usable way and advertise some kind of X-DOVECOT capability? I don't really like the idea of having a ton of separate X-DOVECOT-* capabilities. Maybe instead just have X-DOVECOT-1 for the current functionality and when more is added X-DOVECOT-2 etc? Then describe in Dovecot wiki page what they actually contain. Thoughts? The current list of features are at least: - STATUS (X-SIZE): Sum of all RFC822.SIZEs in a mailbox. (More efficient than FETCHing them.) - STATUS (X-GUID): Show mailbox's GUID. - SEARCH X-SAVEDBEFORE, X-SAVEDON, X-SAVEDSINCE: Search with message's saved-timestamp. - FETCH X-SAVEDATE: Fetch message's saved-timestamp. - SEARCH & FETCH X-GUID: Search/fetch message GUID - SEARCH X-MAILBOX, FETCH X-MAILBOX, FETCH X-REAL-UID: With virtual mailboxes search/fetch the mail's physical mailbox name and message UID. - X-CANCEL <tag>: Stop a (long-running) command, which once in a while goes back to the main loop. For example SEARCH or FETCH.

how to solve : Dovecot version mismatch: Master is v2.1.7, lmtp is v2.2.13
by Dave Myers 22 Sep '14

22 Sep '14

Hello again dovecot list ;) I've recently upgraded my dovecot version from 2.1.7 to 2.2.13. both versions where installed from source. I upgraded why attempting to get lmtp working. I ultimately just coped the executable lmtp to the location that dovecot was expecting it to be in. but then the above error appeared. However when I get the info from dovecot I get the following... $ dovecot -n # 2.2.13: /usr/local/etc/dovecot/dovecot.conf so there seems to be an issue somewhere. I should note that I had copied my previous /conf.d/ files and then copied them back after the update. I guess that I have missed a switch during the build, or need to modify a line in the config somewhere that tells what the version is, but that doesn't explain why the dovecot -n returns the correct info, but the error reports something different. I am considering inserting the version_ignore=yes config option, but where should I insert it ? Thanks in advance.

dovecot´s multiple quota roots
by Andreas Kasenides 22 Sep '14

22 Sep '14

I am trying to find out how Dovecot behaves when there are multiple quota roots. I could not find something authoritative on this. For example, on a nicely running server that used fs quota I now have in 90-quota.conf > plugin { > quota = fs:Mail Quota:user:mount=/Mail > quota2 = maildir:Mail User Quota > } When I do > > doveadm quota get -u atrige01 > Quota name Type Value Limit > % > Mail Quota STORAGE 80036 204800 > 39 > Mail User Quota STORAGE 79306 - > 0 > Mail User Quota MESSAGE 304 - > 0 Apparently both STORAGE quotas values are the same. The question is which of the two is being used by Dovecot. If I insert a limit on the maildir quota which of the two will be used? I am using Dovecot 2.2.12. thank you

Thank you all for your assistance. I was able to locate another web site that mentioned I needed to compile dovecot with my openldap libraries. I then compiled dovecot in the following manner: CPPFLAGS=-I/usr/local/openldap/include \ LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/tmp/tocevod --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This then included the openldap libraries. I tested access and now it works. ldd on /dovecot/libexec/dovecot/auth showed the openldap libraries. libdovecot.so.0 => /usr/local/tools/dovecot/lib/dovecot/libdovecot.so.0 libpam.so.1 => /usr/lib/libpam.so.1 libldap-2.4.so.2 => /usr/local/openldap/lib/libldap-2.4.so.2 libsasl.so.1 => /usr/lib/libsasl.so.1 libssl.so.0.9.7 => /usr/sfw/lib/libssl.so.0.9.7 libcrypto.so.0.9.7 => /usr/sfw/lib/libcrypto.so.0.9.7 liblber-2.4.so.2 => /usr/local/openldap/lib/liblber-2.4.so.2 libresolv.so.2 => /usr/lib/libresolv.so.2 libgen.so.1 => /usr/lib/libgen.so.1 librt.so.1 => /usr/lib/librt.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libsendfile.so.1 => /usr/lib/libsendfile.so.1 libc.so.1 => /usr/lib/libc.so.1 libgcc_s.so.1 => /usr/sfw/lib/libgcc_s.so.1 libcmd.so.1 => /usr/lib/libcmd.so.1 libmd.so.1 => /usr/lib/libmd.so.1 libaio.so.1 => /usr/lib/libaio.so.1 libmp.so.2 => /usr/lib/libmp.so.2 libscf.so.1 => /usr/lib/libscf.so.1 libdoor.so.1 => /usr/lib/libdoor.so.1 libuutil.so.1 => /usr/lib/libuutil.so.1 libssl_extra.so.0.9.7 => /usr/sfw/lib/libssl_extra.so.0.9.7 libcrypto_extra.so.0.9.7 => /usr/sfw/lib/libcrypto_extra.so.0.9.7 libm.so.2 => /usr/lib/libm.so.2 Thanks again.

Support of unicode in then recipient names
by Александр Егоров 19 Sep '14

19 Sep '14

Hi Dovecot Community, We are using ltmp to deliver messages through postfix to dovecot. During testing we have found that dovecot does not understand recipient email address if it is composed from national symbols : e.g. ยจฆฟคฏข(a)xn--22cdfh1b8fsa.xn--22cdfh1b8fsa Question is are there any plans to either add native support for such email addresses or to translate it to punycode and then try to find such a recipient? -- Александр Егоров (Alexander Yegorov)

Syslog PID

Hi! How to write PIDs to syslog? Example: Sep 19 00:57:00 hostname dovecot: pop3-login: Login: user=< username(a)domainname.com >, method=PLAIN, rip=XXX.XXX.XXX.XXX, lip=XXX.XXX.XXX.XXX, mpid=14407, TLS, session=<6LYlcmYDAQC4reGs> Sep 19 00:57:00 hostname dovecot: pop3( username(a)domainname.com ): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Sep 19 00:57:09 hostname exim[14423]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front) Sep 19 00:57:09 hostname exim[14424]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front I need it because i write all logs to postgresql and analyze them with Adiscon LogAnalyzer. Perhaps, per-process logs entry with PID would be better.

unable to see mail when using telnet / open ssl

Dear dovecot list. I'm setting up my own VPS and working through getting mail to work. Here is my dovecot -n $dovecot -n maildir:%h/%d/%n/mail : layout=fs # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail: layout=fs mail_uid = 1002 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 = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes I can successfully log into dovecot using telnet and open ssl from a remote terminal, so authentication and everything is working fine. From the above dovecot -n I asume that mails should be going to /var/mail/virtual/domain/user/mail However when I view this directory I can see a number of test mails that I have sent using echo "Hello me" | mail -s "Dovecot test" $USER (see http://wiki2.dovecot.org/FindMailLocation) Why am I not seeing them when I use telnet / openSSL to log in? All help is greately appreciated. -- Tel: + 33 6 50 14 39 34 email: david.myers.24j74(a)gmail.com Addres: 22 Rue de L'Eglise 77700 Coupvray. 77700 France

negative auth cache?
by Will Yardley 19 Sep '14

19 Sep '14

I am using Dovecot 2.2.13, which doesn't yet seem to have the $auth_cache_negative parameter. Should the negative cache value honor $auth_cache_ttl then? I had a problem where some of our ldap systems were reinitialized. Some users, presumably those who tried to login while their records were returning a failure, became unable to login after the records were once again returning normally. I currently have: auth_cache_size = 5 M auth_cache_ttl = 5 mins # Not yet implemented #auth_cache_negative = 2 mins yet the problem seemed to persist for more than an hour. Also, how can I flush the cache for a non-default instance's cache using doveadm -- "doveadm auth cache flush" doesn't seem to have an '-a' option AFAICT. # doveadm auth usage: doveadm [-Dv] [-f <formatter>] auth <command> [<args>] cache flush w

LDAP and dovecot
by dovecot＠outputservices.com 19 Sep '14

19 Sep '14

At my company I have users who are now becoming remote and using their mobile devices for email. I use Solaris 10 10/09 s10x_u8wos_08a X86 as an operating system and I now need a more secure email solution than the generic sendmail / imap solution. I want to use dovecot and postfix because I have read good reports on these products for ease of setup and use. I need to use both with SSL certificates and username / passwords for both receiving and sending emails. I am having difficulty getting dovecot to work with my ldap password solution. I have read all the documentation, there is a lot of it, and find it confusing. But I have tried very hard to get the solution to work. I have not compiled postfix because I want to use the dovecot authentication solution it mentions. Therefore I need to get dovecot to work first. I have dovecot 2.2.10 & postfix 2.11.1 with openldap 2.4.33. I have tested dovecot with /etc/passwd /etc/shadow password authentication and password flat files. Those work, but not what I need. I need to use ldap so the users only have to set one password. Below is the information I have. I have created self signed SSL certificates for testing purposes. We will get real SSL certificates once everything is operational. ********* I compiled dovecot with the following command: ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes ------------------------------------------- dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } ------------------------------------------- /dovecot/etc/dovecot/tests/ldap.settings hosts = ldap.outputservices.com tls = no ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com ------------------------------------------- If I use ldap for passwords: 2014-09-18 09:44:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:44:33 auth: Fatal: LDAP: Buggy LDAP library returned wrong fd: 1 2014-09-18 09:44:33 master: Error: service(auth): command startup failed, throttling for 2 secs 2014-09-18 09:44:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<> , rip=137.106.101.127, lip=137.106.76.215, TLS handshaking, session=<d1Nt3FgD1wCJamV/> 2014-09-18 09:44:48 master: Warning: Killed with signal 15 (by pid=18992 uid=0 code=kill) ------------------------------------------- If I use a flat file for passwords: 2014-09-18 09:42:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:43:05 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=16769, TLS, se ssion=<vAny1VgDywCJamV/> 2014-09-18 09:43:05 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:43:05 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:43:10 imap(dave): Info: Disconnected: Logged out in=223 out=1122 2014-09-18 09:43:22 master: Warning: Killed with signal 15 (by pid=17115 uid=0 code=kill) ------------------------------------------- If I use /etc/passwd /etc/shadow for passwords: 2014-09-18 09:39:56 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:40:14 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=13053, TLS, se ssion=<uaT5zFgDwACJamV/> 2014-09-18 09:40:14 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:40:14 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:41:01 imap(dave): Info: Disconnected: Logged out in=219 out=1118 2014-09-18 09:41:33 master: Warning: Killed with signal 15 (by pid=14765 uid=0 code=kill) ------------------------------------------- I am using openldap 2.4.33.

I want to stop solaris versions of sendmail and use dovecot & postfix. I am also a little confused on the mail_location setting. We use thunderbird as an email client and it sets the "local folders" just fine. But with imap it puts the Sent, Trash, Draft folders in the users "home" directory. With dovecot I have to put them in a different folder, I called it posta for now. It then makes them . Files. (.Sent, .Trash ?)
