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
by Bernd Kuhls 29 Oct '14

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

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
by Hans Morten Kind 26 Oct '14

26 Oct '14

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

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 # internal names are: # uid - System UID # gid - System GID # home - Home directory # mail - Mail location # # There are also other special fields which can be returned, see # http://wiki.dovecot.org/UserDatabase/ExtraFields user_attrs = pager=home=/mailboxes/%$/%u,mobile=quota_rule=*:storage=%$M If the mail is sent to the Principal SMTP (user1(a)domain1.com) in which the user part (%u) is the same as sAMAccountName, it works. 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...

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.

Dovecot Auth Issue

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
