[Dovecot] Dovecot, mysql, and quota
by David Mehler 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.2 and wanting to get quotas going. I've got the plugins loaded appropriately and am wanting to configure a dictionary backend to talk to my mysql database. I've got a single database called mail which has all the mail-related items in it. One table is for virtual users which postfix uses. It looks like this: CREATE TABLE `virtual_users` ( `id` int(11) NOT NULL auto_increment, `domain_id` int(11) NOT NULL, `password` varchar(128) NOT NULL, `email` varchar(100) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8; and a user looks like: INSERT INTO `mail`.`virtual_users` ( `id` , `domain_id` , `password` , `email` ) VALUES ( '1', '1', SHA2( 'PasswordGoesHere', 512) , 'username(a)domain.com' ); plugin { # SQL backend: quota = dict:User quota::proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Now when creating the quota table i'd like to have the username field linked to my virtual_users table username field, so I don't have to set up two tables both with the same username information in it. Can someone check me on this design so that if I delete a virtual user out of the virtual_users table the coresponding row in the quota table is also eliminated? My second question has to do with global and per user quotas. If I have something like this: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 262144, messages integer not null default 0, primary key (username) ); 256MB for all users by default, but then if I give a user a 100MB value in the bytes field of their quota entry would that be a per-user quota? Thanks. Dave.

[Dovecot] Index corruption with 2.2.12 when moving a message
by Bojan Smojver 19 Feb '14

19 Feb '14

Just bumped into this today, when I upgraded to a testing package in Fedora: https://admin.fedoraproject.org/updates/FEDORA-2014-2672/dovecot-2.2.12-1.f… For details, see this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1066709 Haven't seen this kind of thing before. Sure, it worked the second time I tried to move the message to another folder (I'm guessing index got rebuilt or something), but still, looks suspicious. Anyway, I'm using mbox format mailboxes, if it matters. Client was Gnome Evolution 3.10.4. -- Bojan

[Dovecot] Problems with dovecot 2.1.7, spamassassin 3.3.2 and antispam plugin
by Dean Carpenter 18 Feb '14

18 Feb '14

This might be a fairly long message, but I wanted to be sure to include as much information as possible. I'm having an issue with the dovecot-antispam plugin in that it seems to be unable to successfully run anything from the pipe backend. To qualify that, they run, but they fail ... Running /usr/bin/sa-learn directly always returns with an error code of 1, and the bayes DB isn't actually updated. Running the /usr/local/bin/sa-learn-pipe.sh script from the example will run sa-learn successfully, but sa-learn fails partway through, right on a sql DB access. I have both bayes and FuzzyOcr data stored in mysql, and the error occurs on accessing either one. That is, I've tested with FuzzyOcr enabled, and it fails on the db access to the FuzzyOcr DB, and I've tried it with FuzzyOcr disabled. In that case, it fails on the access to the bayes DB. The error line right there is : libgcc_s.so.1 must be installed for pthread_cancel to work Since sa-learn terminated prematurely, the bayes DB isn't updated at all. Running /usr/bin/sa-learn or the script /usr/local/bin/sa-learn-pipe.sh directly from cmdline works fine though - sa-learn completes correctly and updates the bayes DB properly, I can see the new tokens. $ sa-learn-pipe.sh --spam < /usr/share/doc/spamassassin/examples/sample-spam.txt $ sa-learn --spam /usr/share/doc/spamassassin/examples/sample-spam.txt I think it would be great to have a dedicated logfile for antispam, one that would capture both stdout as well as stderr. These tests are being done on a clean Ubuntu 13.04 system. I'm rebuilding the VM repeatedly as I configure the various pieces, and can test any changes or whatever you might suggest very easily. I've fully scripted the install and configuration of Exim4, Dovecot, Spamassassin, Clamav, Percona/Mysql, Roundcube, and can build a full VM under Virtualbox or any VPS in less than 10 minutes. Ubuntu 13.04 Dovecot 2.1.7 dovecot-antispam 2.0+20120225-3 Anyone else using the antispam plugin with spamassassin 3.3.2 ?

[Dovecot] SMTP configuration for director mail cluster
by Murray Trainer 18 Feb '14

18 Feb '14

HI All, I have setup my Dovecot director proxies and Dovecot backend mail stores. I intend setting up several incoming and outgoing Exim MTA's. I am a bit confused about what I need to run on the backend Dovecot MTA's to get the incoming mail delivered to them. Do I need to install Exim on them or use LMTP to receive mail from the MTA's? Also, can I directly deliver mail to the mailstores or do I have to go through the director proxies using lmtp? Note that I am using Director with the mailboxes on NFS backed storage. Thanks Murray

[Dovecot] PARTIAL results and UIDs
by Anders Thøgersen 18 Feb '14

Hi, I have had a look at dovecot 2.2.12 and think that I may have run into an issue with PARTIAL results. I have a mailbox with 9 emails having UIDs from 1 - 9. One of these emails contains the STRING "RFC" in the Subject header. The following SORT command with this mailbox selected does not return any emails: A4 UID SORT RETURN (COUNT PARTIAL 1:3) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:3 NIL) COUNT 1 A4 OK Sort completed (0.000 secs). Here COUNT is 1, but the result is NIL. Changing the partial range to 1:5 returns the expected result: A4 UID SORT RETURN (COUNT PARTIAL 1:5) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:5 5) COUNT 1 A4 OK Sort completed (0.000 secs). It may be that UIDs are used instead of sequence numbers. Regards Anders

[Dovecot] Possible error in function mailbox_autocreate
by Potapov Sergey 18 Feb '14

18 Feb '14

Hi! in mailbox_autocreate: if (mailbox_create(box, NULL, FALSE) < 0) { errstr = mailbox_get_last_error(box, &error); if (error != MAIL_ERROR_NOTFOUND) { <<< May be MAIL_ERROR_EXISTS should be here? mail_storage_set_critical(box->storage, "Failed to autocreate mailbox %s: %s", box->vname, errstr); return -1; } Some time I got this error when two connections tries to create INBOX at same time. ______ С уважением, Сергей Потапов

[Dovecot] Dsync crash (v2.2.10, sdbox+sis → mbox)

Hi, I'm trying to use dsync to convert sdbox + sis mailboxes to mbox (mbox is chosen here to "re-attach" the attachments to their original place) # dsync -Dv -u $LOGIN -o

[Dovecot] The submission server
by Peter Mogensen 18 Feb '14

18 Feb '14

Hi, As many others I'm looking forward to the submission server. But I have a question: A use-case with authenticated SMTP is to have the server restrict From/Sender headers based on the authenticated user. (and adding the actual authenticated user to the headers) Postfix supports this (AFAICS) and I can't imagine Exims doesn't either with it's elaborate config possibilities. But will that be possible with the Dovecot submission server? /Peter

[Dovecot] Master user ldap config
by Roman Gelfand 17 Feb '14

17 Feb '14

I am using outlook 2010 to login to pop3 mailbox as master user. The user name I provide is john@domain.tld*test@domain.tld. The password is that of test(a)domain.tld. I am not quite sure as to how to specify ACL. I guessed the ACL specs as per ldap config, below. But it is not working. The master password is stored in master-users file.

Re: [Dovecot] Crash in pop3 with recent dovecot, backtrace

Hi, I have the same crashes in pop3 with the recent dovecot release 2.2.11 on Fedora 16 x86_64. The log file shows: dovecot: pop3(username(a)example.com): Fatal: master: service(pop3): child 26735 killed with signal 11 (core dumped) New mails will be successfully fetched by the client but all the dovecot files in the users maildir (dovecot.index.log, dovecot.index.cache, ...) are not being updated anymore.

[Dovecot] FTS question
by Peter Chiochetti 14 Feb '14

14 Feb '14

Please advise: Can I override the user parameter in solr indexing and searching? To understand, why I wish for that, please consider my setup: # Mail is fetched from a remote imap server # dovecot LDA stores into Maildir as system user # Several virtual users exist in a static userdb # They all share the system users Maildir # everybody can see, move, delete etc. all the mails # dovecot mail_log plugin is used for audit So it is like all/only shared folders, isn't it? A cheap groupware, maybe… This works exceptionally well (2.0 and 2.2.11 as of now). The problem: When e-mails are indexed by solr, the uid of the virtual user is passed on, and only this user will later find that mail in a server side body search. I tried and made "user" an ignored field in solr schema, but then nothing will ever be found, because it is dropped when indexing, but will be asked for in searching. So far, what I learned in a day. Maybe someone can help? Thank You in advance -- peter

Re: [Dovecot] Maildir format
by Roman Gelfand 14 Feb '14

I am not sure where I went wrong here. The wiki says... By default Dovecot uses Maildir++ directory layout for organizing mailbox directories. This means that all the folders are directly inside ~/Maildir directory: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX. The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. ~/Maildir/.folder/ is a mailbox folder ~/Maildir/.folder.subfolder/ is a subfolder of a folder (ie. "folder/subfolder") You can also optionally use the "fs" layout by appending :LAYOUT=fs to mail_location. This makes the folder structure look like: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX, just like with Maildir++. ~/Maildir/folder/ is a mailbox folder ~/Maildir/folder/subfolder/ is a subfolder of a folder Here is my folders. Though there are emails in the inbox, I am not seeing anything in new/ or cur/ folders. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.doe/Maildir/ drwx------ 5 999 mail 4096 Feb 14 10:06 . drwx------ 3 999 mail 4096 Feb 12 19:53 .. drwx------ 2 999 mail 4096 Feb 14 10:02 cur -rw------- 1 999 mail 17408 Feb 14 10:02 dovecot.index.cache -rw------- 1 999 mail 2896 Feb 14 10:06 dovecot.index.log -rw------- 1 999 mail 51 Feb 14 10:06 dovecot-uidlist -rw------- 1 999 mail 8 Feb 12 19:53 dovecot-uidvalidity -r--r--r-- 1 999 mail 0 Feb 12 19:53 dovecot-uidvalidity.52fc176c drwx------ 2 999 mail 4096 Feb 14 10:02 new drwx------ 2 999 mail 4096 Feb 14 09:59 tmp root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/new total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 .. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/cur total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 ..

[Dovecot] Hybrid of linux user accounts and virtual user accounts configuration
by Derek Winterstien 14 Feb '14

14 Feb '14

So some system users have their email forward to Maildir in their /home/user directory (virtual_alias_maps) for their domain . This I have working! And the rest are non-system users, ie virtual users listed in a plain text file and their MailDir will be in /home/vmial/domain.com/user/ The virtual user part is working 100% with postfix and dovecot accepting mail for each virtual alias and system account holders popping in to retrieve their mail. The second part is working 50%. I have email for virtual users going into /home/vmail/domain.com where they are supposed to go. Now, I am very confused on how to configure dovecot to allow folks without system accounts to login and retrieve their email. I have been going through one guide after another. When I start changing things I break the first working part, the system accounts being able to get their mail. Changes to dovecot.conf to get the second working negatively impact the first. Also, a lot of documentation is out of date, which further complicates matters. Postfix/Dovecot: Postfix version: 2.6.6 Dovecot version: 2.0.9

[Dovecot] Feature request about Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths)
by Steffen Kaiser 14 Feb '14

14 Feb '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since some time I'm plagued by internal login failures. With v2.2.10 I got the some additional error, that I should raise the process_limit for the imap service, then I got the hint to raise vsz_limit for the lmtp and imap serverices. These hints are very helpful and are some sort of unique feature of Dovecot - descriptive error messages. Now I have upgraded a Webfrontend behind imapproxy -> Dovecot and get this during a phase in the day, several of messages go to large internal mailing lists and lots of users are connecting/disconnecting via IMAP, POP,& Web: <login success> imap: Error: Disconnected from auth server, aborting (client-pid=2296 client-id=17278) imap-login: Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths) .... . doveadm and to query the userdb [I have some processes that use Dovecot UserDB to query user data, which do not cache its information], & login into IMAP fail as well. Even connecting to the auth-userdb socket reveals no reaction - usually the VERSION prompts immediately. I now suppose that the deault auth_worker_max_count=30 is the culprit, because I query LDAP for passdb and userdb and client_count, but client_limit=0. Would it be possible to add a warning to all limits "that max out"? Or, if such "generic error" occurs, could Dovecot be enabled to dump a list of which limit is used up to which level? Or something like that. Also, I'm surprised to find that the "Internal login failure" is at "Info" level only. Also note: It is very possible that the problem is caused by a client that goes havoc. ====== Just to no trigger the "post your config" reply I give now and then myself: # 2.2.10 (5432b55a2b87): /usr/local/dovecot-2.2.10/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.8 auth_cache_size = 10 M auth_debug = yes auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot2.2/ default_vsz_limit = 512 M deliver_log_format = msgid=%m: %$ %p/%w "%f" "%s" dict { acl = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext quota = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext } instance_name = dovecot2.2 lda_mailbox_autocreate = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot/dovecot2.2.log log_timestamp = "%F %H:%M:%S " mail_debug = yes mail_gid = vmail mail_log_prefix = "%Us(%u) [%p]: " mail_max_userip_connections = 0 mail_plugins = " quota notify mail_log zlib acl" mail_shared_explicit_inbox = yes mail_uid = vmail 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 imapflags namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = users.%%u. separator = . type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = proxy::acl antispam_allow_append_to_spam = yes antispam_backend = spool2dir antispam_spam = SPAM+ReportAsSPAM antispam_spool2dir_notspam = /tmp/spamspool/%%020lu-%%05lu-%u-H antispam_spool2dir_spam = /tmp/spamspool/%%020lu-%%05lu-%u-S antispam_trash = trash;TRASH;Trash;spam;SPAM;Spam;junk;JUNK;Junk;Deleted Items;Deleted Messages;Gel&APY-schte Elemente;Gel&APY-schte Objekte;Junk E-mail;Junk-E-Mail;INBOX.Trash;INBOX.TRASH;INBOX.trash mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size vsize from subject quota = dict:User quota::proxy::quota quota_rule = *:storage=300MB quota_rule2 = Trash:storage=+30M recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags sieve_max_actions = 0 sieve_quota_max_storage = 3M } protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener auth-client { mode = 0766 } unix_listener auth-userdb { mode = 0766 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service doveadm { unix_listener doveadm-server { mode = 0666 } } service imap-login { process_min_avail = 4 service_count = 0 vsz_limit = 768 M } service imap { process_limit = 10000 vsz_limit = 768 M } service lmtp { vsz_limit = 768 M } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { process_min_avail = 5 service_count = 0 vsz_limit = 512 M } ssl_ca = </etc/ssl/certs/ca.crt ssl_cert = </etc/ssl/certs/imap.pem ssl_key = </etc/ssl/private/imap.key userdb { driver = prefetch } userdb { args = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext default_fields = home=/home/%u uid=vmail gid=vmail driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol lda { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol imap { mail_plugins = " quota notify mail_log zlib acl imap_quota imap_zlib imap_acl antispam" } - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUvjzZnD1/YhP6VMHAQKElQgAoBU3v5JD9kFNzan06UFG88sucvf6HZru gLF6l7IZSWiY/IwouTBoseJcrXmgVG9sCk12gxvonO3iT0KVu1PyJZeTMaKtY3hS I37J4iS88pmY3cGQNguYMSidrIvNOt6SW+Jv/9QxuYTJKYCqoEZRdP8yJ+dvrmQw zpZEzKqcV+x4ofDLcpRxLZtXwb+Bl5AA9hoe/Md/UqzUEa9CYyvANoX63/zY7WS5 1VpK+a80/L6ukJUt9tPQTWSe0ALYmL6Cd4tAdC2Bsq7rN+6SQIcjxxr/9v8Byj8Q BdtwUhpTazVm7CLOjnFiWxfXmHCL9BNrQUBBAd5docSydNDEUMmQng== =r9QR -----END PGP SIGNATURE-----

Hello, I have some Issues with Dovecots public folder. I only see the folder in users Mailbox but I cannot subscribe it or copy mails in it.

[Dovecot] Status
by Timo Sirainen 14 Feb '14

14 Feb '14

So, just some quick notes: - dovecot.org server was down a couple of days again, need to find time to move it to a VM.. - my tss(a)iki.fi emails were also broken for some hours at least and it was bouncing back all mails to it during the time - I fixed some bugs reported by people, but I did it in airplane so couldn't reply back with links to the fixes in hg repo. I'll probably do that tomorrow. But you can already check if your reported bug has been fixed in http://hg.dovecot.org/dovecot-2.2 - I'm planning on going through Dovecot list's mails this week and make v2.2.11 release - although it looks like I've a flu, so lets see how far I can get.. - hopefully by the beginning of March I'll have more time again

[Dovecot] Sieve is not getting the propper RCPT from the LMTP daemon
by klondike 14 Feb '14

14 Feb '14

Hi! Since the setup I use is a bit strange let's go for it first: * The system uses postfix as MTA and dovecot as LDA after alias translation by local via LMTP * The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1 * The SMTP server at gentoo.org is configured to send me a backup of my emails to klondike+gentoo (at) xiscosoft.es using sendmail * The email is received by the server and then (hopefully filtered). * The email comes with two Delivered-To: headers, the first one has the correct address, the second one has the gentoo address. The interesting part of the filter is this: if envelope :detail "to" "gentoo" { addflag "\\Seen"; fileinto "gentoo"; stop; } But this doesn't seem to work, I enable debugging with the following lines: require "vnd.dovecot.debug"; require "envelope"; require "variables"; if envelope :matches "to" "*" { debug_log "envelope to `${1}'"; } if envelope :matches "from" "*" { debug_log "envelope from `${1}'"; } The relevant lines for the test e-mail I sent are these: sieve: info: started log at Dec 24 13:37:23. main script: line 9: info: DEBUG: envelope to `klondike (at) gentoo.org'. main script: line 10: info: DEBUG: envelope from `klondike (at) gentoo.org'. info: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX'. The thing is that the to envelope should be instead klondike+gentoo (at) xiscosoft.es as show by the lmtp logs: Dec 24 13:37:23 localhost dovecot: lmtp(26249): Connect from local Dec 24 13:37:23 localhost dovecot: lmtp(26249, klondike): Cd6YHwOAuVKJZgAA0J78UA: sieve: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX' Dec 24 13:37:23 localhost dovecot: lmtp(26249): Disconnect from local: Successful quit Dec 24 13:37:23 localhost postfix/lmtp[26248]: 657D9101E5E: to=<klondike+gentoo (at) xiscosoft.es>, relay=xiscosoft.net[private/dovecot-lmtp], delay=0.29, delays=0.05/0.03/0.03/0.18, dsn=2.0.0, status=sent (250 2.0.0 <klondike+gentoo (at) xiscosoft.es> Cd6YHwOAuVKJZgAA0J78UA Saved) I really have no idea of why sieve is behaving like this as the evelope address is sent properly by postfix's lmtp according to the logs. Any ideas? klondike PS: please do CC me when answering this e-mail as I'm not subscribed to the list yet

[Dovecot] master user and ACL's
by Peter Mogensen 14 Feb '14

14 Feb '14

Hi, Quick question...I read in the docs that: "Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user." ... and that the standard workaround is to return master_user=%u from the userdb. But why is the master_user authn-id used in the ACLs and not the authz-id (requested-login-user) ? Isn't the whole point of SASL authz-id semantics to have authorization resolved based on the authz-id? /Peter

[Dovecot] Public folder doesn't work
by vupibi 14 Feb '14

14 Feb '14

Hey, I have some issues with dovecot, because the public folder won't show up in Mail accounts. Dovecot is installed via zentyal 3.3. I tried several settings, but I dont get it running. What I tried is adding this to my dovecot.conf file # User's private mail location mail_location = maildir:~/Maildir # When creating any namespaces, you must also have a private namespace: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/var/vmail/public subscriptions = no } But nothing happened. I tried it with # Umask for shared folders umask = 0007 with subscriptions = yes tried creating the folder first like this touch /var/vmail/public/dovecot-shared chown -R ebox /var/vmail/public find /var/vmail/public -type d -print0 | xargs -0 chmod 2770 find /var/vmail/public -type f -print0 | xargs -0 chmod 660 But i had no success. Any Ideas how to get it running?

[Dovecot] Exclude Users from replication/sync
by Daniel Stoye 14 Feb '14

14 Feb '14

Hi All, i'm searching for a way to exclude certain users from dovecots replication mechanism. I can't use the first_valid_uid setting, because the uid of my pam (ldap) users und my system users are mixed up. So, is there a way to limit my users i currently have in my userdb or somehow exclude specific uids from replication? Thanks, Daniel

[Dovecot] v2.2.12 released
by Timo Sirainen 14 Feb '14

14 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz.sig POP3 server code changes rarely, so I haven't spent time adding automated testing for it. So of course now that it changed in v2.1.11 there was a bug that caused it to crash most of the time (except for the test case I was using while developing it). This release fixes it, no other changes.

[Dovecot] Dovecot 2.2.10 crash / infinite loop bug
by Jani Hast 14 Feb '14

14 Feb '14

Hello, I though this bug should be reported, although there is workaround already made and in use. Dovecot 2.2.10 crashes into out of memory error when there is defined system users (userdb+passdb) and own virtual users (userdb+passdb). Removing either one solves the issue and Dovecot is working as it should. When memory leak (I replaced pw_init and gr_init with the version that is found from 2.1.17) is fixed from lib/ipwd.c source, the auth worker gets to infinite loop and authentication timeouts(timeout was increased, but worker does not end what ever it's doing). This far I got chance to debug this before other passdb was removed due lack of time.

[Dovecot] sqlite queries for master user
by Alan Chandler 14 Feb '14

14 Feb '14

Hi I am trying to achieve the following functionality "usera" can't login because his account is set non active. there is a deny query that checks this. a master user ("masteruser") should be able login using "usera*masteruser" syntax to this disabled account I just tried it with auth_debug set on, but the deny query is being run for usera, presumably because my master definition is passdb { driver = sql master = yes args = /etc/dovecot/sqlite-master.conf # Unless you're using PAM, you probably still want the destination user to # be looked up from passdb that it really exists. pass=yes does that. pass = yes } with pass=yes, and that causes usera to be validated through both the deny and accept phase of authorisation. In the password_query defined in sqlite-master.conf I user '%u' to locate my master user. Is there any variable I could use to (in that query) to also check that "usera" exists? I could then remove the pass = yes, both to avoid two more queries and to avoid the trap that this account is locked out. Alternatively some other parameter in the passdb segment above to tell the other login to miss the deny stage.

http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz.sig I haven't had time to read through the Dovecot mailing list yet, so there are likely some reported bugs that haven't been fixed yet. I'll try to get to them next week in San Francisco. (Probably can't get much done this week in Tokyo.) In the mean time here's v2.2.11 with some new features. + acl plugin: Added an alternative global ACL file that can contain mailbox patterns. See http://wiki2.dovecot.org/ACL for details. + imap proxy: Added proxy_nopipelining passdb setting to work around other IMAP servers' bugs (MS Exchange 2013 especially). + Added %{auth_user}, %{auth_username} and %{auth_domain} variables. See http://wiki2.dovecot.org/Variables for details. + Added support for LZ4 compression. + stats: Track also wall clock time for commands. + pop3_migration plugin improvements to try harder to match the UIDLs correctly. - imap: SEARCH/SORT PARTIAL reponses may have been too large. - doveadm backup: Fixed assert-crash when syncing mailbox deletion.

Murry my mail delivery is working fine. The first message even automatically creates the Maildir structure like it should, all permissions correct. Steffen Kaiser I will place the output of dovecot n at the bottom of this message. I've configured checkpassword which should be a script that comes with dovecot.

[Dovecot] Getting Director Proxy Working

Hi All, I can't get directory proxying of pop3 and imap working. The director stuff appears to be OK - see below. The ldap authentication is working on the backend mail server. I just get connection refused when I telnet to the proxy on the pop3 and imap ports. Nothing appears to be running on the pop3 and imap ports despite the lines in the config below.

[Dovecot] can not see public mailbox
by David Mehler 13 Feb '14

Hello, I'm running Dovecot2 and trying to set up public mailboxes. I've got a virtual user system set up with postfix and using MySQL authentication. I'm wanting to create several public mailboxes for shared messages. I've followed the wiki and have the public folder created. I've got a folder /home/vmail/public/public1 public1 being the maildir of the public mailbox. I can see in my folder list of my webmail client the root public folder but I can't change in to it and I can not see the public1 public mailbox. I'm using one user vmail set up for this setup, permissions on the public1 folder allow the vmail user to read and execute. In public1 I have a file dovecot-acl which has the user attempting to access the public folder with the flags l and r. Below is my config with doveconf -n. I'd appreciate any suggestions. Thanks.

[Dovecot] Order of istream and ostream chains
by Philipp Brüll 12 Feb '14

12 Feb '14

Hi, I'm creating a scrambler plugin, that adds an istream and an ostream to the stream-chain for the mail input/output. It works well until the zlib plugin is added to the configuration. The scrambler should run before the zlib and encrypt the mail before it's compressed. Since, the plugin is named lib18_scrambler_... (and the other lib20_zlib....), that works well when a mail is received. When a mail is read via IMAP, the plugins should handle the mail in the reverse order. So first, the zlib should decompress it and afterwards the scrambler should decrypt it. But it seems, that they work the other way around. The scrambler istream gets compressed data as input. It's hooked in the chain of istream as the following... static int scrambler_istream_opened(struct mail *_mail, struct istream **stream) { struct mail_private *mail = (struct mail_private *)_mail; union mail_module_context *mmail = SCRAMBLER_MAIL_CONTEXT(mail); struct istream *input, *inputs[2]; input = *stream; *stream = scrambler_istream_create(input); i_stream_unref(&input); return mmail->super.istream_opened(_mail, stream); } static void scrambler_mail_allocated(struct mail *_mail) { struct mail_private *mail = (struct mail_private *)_mail; struct mail_vfuncs *v = mail->vlast; union mail_module_context *mmail; mmail = p_new(mail->pool, union mail_module_context, 1); mmail->super = *v; mail->vlast = &mmail->super; v->istream_opened = scrambler_istream_opened; MODULE_CONTEXT_SET_SELF(mail, scrambler_mail_module, mmail); } How can I reverse the order of istreams? Should I use another hook or vfuns? I'm stuck in the problem for a while now, so any help would be very welcome. Best regards, Philipp

[Dovecot] personal sieve script not included
by Thomas Krause 12 Feb '14

12 Feb '14

Hello, I'm using dovecot 2.2.10 and roundcube (with managesieve enabled). Sieve filtering works well, as long the rule is written into ~/.dovecot.sieve (which is a link to ~/sieve/managesieve.sieve) When adding a new filter set (in roundcube) the script is written to ~/sieve/newfilterset.sieve. This script will not be executed. How can I solve this? I set sieve_dir = ~/sieve This should work, except I misunderstand the doc. # ls -l ./sieve total 6 -rw------- 1 vmail mail 105 Feb 5 09:24 managesieve.sieve -rw------- 1 vmail mail 113 Feb 4 16:30 test.sieve drwx------ 2 vmail mail 512 Feb 5 09:24 tmp Regards, Thomas.

[Dovecot] Problem rebuilding Centos 5/6 pigeonhole RPM from mercurial version
by Juan C. Blanco 12 Feb '14

12 Feb '14

Hi Stephan, I'm traying to rebuild the RH (Centos) EL5 and EL6 RPM with the last mercurial pigeonhole 0.4.2 version, but I'm having problems with the build. I think that I've isolated the problem outside rpmbuild context. I've downloaded dovecot and pigeonhole mercurial versions and built dovecot with the commands: dovecot-2.2.10$ ./autogen.sh dovecot-2.2.10$ ./configure INSTALL_DATA="install -c -p -m644" --enable-header-install --disable-static --with-nss --with-shadow --with-pam --with-gssapi=plugin --with-ldap=plugin --with-sql=plugin --with-mysql --with-zlib --with-sql-drivers --with-libcap --with-db --with-ssl=openssl --with-ssldir=/etc/pki/dovecot --with-notify=inotify --with-solr --with-docs dovecot-2.2.10$ make dovecot-2.2.10$ make install DESTDIR=/var/tmp/dovecot after that, building pigeonhole with the commands pigeonhole-0.4.2$ ./autogen.sh pigeonhole-0.4.2$ ./configure INSTALL_DATA="install -c -p -m644" --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --target=x86_64-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --with-dovecot=/var/tmp/dovecot --with-managesieve=yes pigeonhole-0.4.2$ make pigeonhole-0.4.2$ make install DESTDIR=/var/tmp/dovecot works fine, but if I install pigeonhole in a different path, i.e. pigeonhole-0.4.2$ make install DESTDIR=/var/tmp/pigeonhole I get the following error make[4]: Entering directory `/home/jc/pigeonhole-0.4.2/src/lib-sieve' make[4]: Nothing to be done for `install-exec-am'. test -z

[Dovecot] RFC 5267 Contexts for IMAP4 PARTIAL results
by Anders Thøgersen 11 Feb '14

11 Feb '14

Hello, I am looking at PARTIAL responses using a dovecot version 2.2.5 and am running into an inconsistency with the RFC which I would like to ask about. The following section http://tools.ietf.org/html/rfc5267#section-4.4 lists client requests and server responses which I have tried running against a folder, specifying the ranges that fit the contents of the folder I have selected. The Last of the listed client requests returns a response that is not as I would expect: C: A04 UID SEARCH RETURN (PARTIAL 24000:24500) UNDELETED UNKEYWORD $Junk should return S: * ESEARCH (TAG "A04") UID PARTIAL (24000:24500 NIL) // No results are present, this is beyond the end of the results. S: A04 OK Completed. according to the RFC, but instead of NIL in the PARTIAL result I see the full range of UIDs that are in the folder, as in: C: A02 UID SEARCH RETURN (PARTIAL 23500:24000) UNDELETED S: * ESEARCH (TAG "A02") UID PARTIAL (23500:24000 1:9) S: A02 OK Search completed (0.000 secs). The folder that is selected contains 9 emails with the UIDs 1-9. Should the server return NIL Instead of returning 1:9? Thanks! Anders

[Dovecot] Undertanding what the lmtp_save_to_detail_mailbox actually does
by Alan Chandler 11 Feb '14

11 Feb '14

Hi I am just learning to setup dovecot as part of a project to move my home mail serving from a large and complex linux computer which is acting as internet router/nat gateway to the internet (this leaving me exposed without internet connection when it goes down) to a raspberry pi - which will be port-forwarded to, when I turn my internet cable modem back into a router/modem. I have chosen to try and do this with a Postfix/Dovecot combination with some key user information coming from an sqlite database. Postfix will use Dovecot for authentication (where needed) and use its lmtp service for local delivery. I have so far got Dovecot working fine for the basic stuff, including using rsync to copy each of my users entire maildir from the old machine to the new to prove that it can be accessed. but I have one last specific piece of functionality I want to achieve that the old system does (and has been doing) for at least 5 years (that is what is still online - I think I have "archived" some older stuff). The existing environment uses a Exim4/Cyrus IMAP combination and with Exim I have managed to develop the rules so that all outgoing mail from my internal clients is copied into a subdirectory of their sent mail folder. The format of the folder is Sent.yyyy.mm where yyyy and mm are computed on the fly from todays date. (the .separator defining a subfolder in the hierarchy) I now have several years of saved messages in my existing system. Postfix has nowhere near the flexibility of Exim to develop rules like that, but I think I could potentially use an sql query on my user database to set up a sender_bcc_map that addressed the result to <sender local part>+Sent.<yyyy>.<mm> (or maybe<senderlocalpart>+Sent/<yyyy>/<mm> and then send that to dovecot. I have then to decide how to handle it. The problem I am facing is I can find no documentation about what lmtp_save_to_detail_mailbox actually causes lmtp to actually do. Searching the wiki refers to it only in the LMTP page. How should the detail of the address be formatted to specify a subdirectory - can it be specified even? Should I be using it? I have seen comments in the past about people recommending using sieve for this sort of thing. and indeed it might be better if I could figure it out, in that 1) I could then send to something more simple like <senderlocalpart>+saveoutgoing and use the "date" extension of sieve to generate the split. 2) Users could ultimately decide what to do them selves with this tag (and I could define a global "after_sieve" to throw it away. Unfortunately my reading of the fileinto extension is that the destination can only be a literal string and not a "computed" value based on the date. UNLESS anyone knows different? I would welcome any advice anyone could give me Thanks Alan Chandler

[Dovecot] Sieve - Not showing new emails in Thunderbird?
by craig.dovecot＠noboost.org 11 Feb '14

11 Feb '14

Hi, Issue: Sieve works perfectly and does deliver the mail to the correct mail directories. However Thunderbird doesn't detect the new email, until the user clicks on the folder and then all of a sudden it shows the newly detected emails. Perhaps this is a task for the Thunderbird forums? (Thunderbird 24.2.0) Server Side: * CentOS release 6.3 (Final) * dovecot-2.0.9-7.el6.x86_64 * dovecot-pigeonhole-2.0.9-7.el6.x86_64 * postfix-2.6.6-2.2.el6_1.x86_64 * Server Sieve Settings: mail_location = maildir:~/Maildir plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_vacation_default_period = 10d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1h } * Client App: - Thunderbird 24.2.0 * Userlevel config; File: ~/.dovecot.sieve require "fileinto"; if address :is "to" "sysadmin(a)example.com" { fileinto "sysadmin"; } elsif address :is "to" "root@" { fileinto "sysadmin"; } elsif address :is "from" "root@" { fileinto "sysadmin"; } cya Craig

[Dovecot] Looking for HowTo Postifx, Dovecot and PostgreSQL
by Frank Lanitz 10 Feb '14

10 Feb '14

Hi folks, I know it's a bit a n00bish question, but I'm a little confused about this many different ways on setting up dovecot with postfix and using a PostgreSQL backend for virtual hosts. I've found this one quiet helpful: http://wiki2.dovecot.org/HowTo/DovecotPostgresql even it seems to be little outdated for recent versions of dovecot (the auth part of dovecot.conf). Also its lagging some inforamtions I wasn't able to find on my own (e.g. how to set password for a imap account). Can somebody give me a hint for a up-2-date howto for some noob as I am? Cheers, Frank

[Dovecot] Dsync Errors

Greetings, I've seen something like this in another thread, about a month ago, but we're running into this error pretty frequently when we run dsync backup.

Can you point me in the right direction to start troubleshooting this? Thanks. -- --Asai

[Dovecot] Auth socket can't listen using ssl
by Anthony Bourguignon 07 Feb '14

07 Feb '14

Hi, I'm using Dovecot 2.2.9 (debian package on testing). It seems that it's not possible to open an auth socket using ssl. I'm using this configuration : service auth { [...] inet_listener authxmpp-client { address = [ips] port = 5220 } inet_listener genericauth-client { ssl = yes address = [ips] port = 5221 } [...] } Both ports are running fine. But the 5221, which should listen in ssl (because of the "ssl = yes" as written in the documentation here : http://wiki2.dovecot.org/Services ) is using plaintext. If I telnet directly to it, the content is delivered on an unsecured socket. Is there a way to make ssl works on this kind of socket ? Thanks a lot

[Dovecot] Multiple ssl-certs on different ports with the same protocol
by myleetlist＠gmx.de 07 Feb '14

07 Feb '14

Hi, is it possible to use multiple ssl-certs on different _ports_ with the same protocol? I know I can configure multiple certs with the "local <ip>" setting*. But how is this (or similar) possible in v2.2.10: local :100 { protocol imap { ... } } local :101 { protocol imap { ... } } This would be useful in a loadbalancing setup, you don't waste IPs and the config files on different servers stay the same. * [http://wiki2.dovecot.org/SSL/DovecotConfiguration]

[Dovecot] Plugin architecture
by Philipp Brüll 06 Feb '14

06 Feb '14

Hi, I'm currently developing a scrambler plugin which should be used to store the mails encrypted on the disk. It uses a special ostream for encryption and an istream for decryption. The idea is, that if a mail arrives via LMTP it goes through the ostream and is written encrypted to disk. If an mail is accessed via IMAP, the istream is used to decrypt the data from disk. That all works fine, but if I add the zlib plugin it all gets mixed up. For some reason, the lmtp process tries to read something from disk using the chain of istreams. That behaviour is a little bit bizzare to me, because my understanding is, that the zlib plugin at this point should only write (compressed) data to disk. Why is the istream used here? And what is read? If I remove zlib from the configuration again, it all works as expected. The dovecot version is 2.1.17. Best regards, Philipp

[Dovecot] Trying to get Dovecot Director Proxying working
by Murray Trainer 06 Feb '14

06 Feb '14

Hi All, Firstly, thanks for all the really helpful responses to my previous questions "Architecture for large Dovecot cluster" and "Sizing MTA servers". I am now trying to get a Dovecot director proxy working with a single backend mail server. When I try to connect to the dovecot proxy on the pop3 and imap ports I get connection refused. I want the authentication to be on the backend mail server initially. I am not sure if I am missing something? More info below... Thanks Murray # doveadm director status mail server ip vhosts users 27.54.95.41 100 0 # doveadm director map doveadm(root): Error: userdb list: Disconnected unexpectedly doveadm(root): Error: user listing failed user mail server ip expire time # doveadm fetch -A user ALL doveadm(root): Error: userdb list: Disconnected unexpectedly doveadm: Error: Failed to iterate through some users # doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 auth_cache_size = 32 M auth_cache_ttl = 2 hours auth_debug = yes auth_verbose = yes base_dir = /var/run/dovecot/ director_mail_servers = 27.54.95.41 director_servers = 27.54.95.37 disable_plaintext_auth = no mail_debug = yes passdb { args = nopassword=y proxy=y driver = static } service auth { unix_listener auth-userdb { mode = 0666 user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director } service ipc { unix_listener ipc { user = dovecot } } service pop3-login { executable = pop3-login director } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=dovenull gid=dovenull home=/var/run/dovecot/empty driver = static }

[Dovecot] LMTP troubles
by Phillip Odam 06 Feb '14

06 Feb '14

Background: Dovecot: v 2.0.9 OS: AWS Linux (derived from CentOS) At this stage I've avoided upgrading to a newer version of Dovecot as version 2.0.9 is what AWS Linux provides and I'd like to be able to run a regular AWS Linux installation if I can. As opposed to pulling newer versions of dovecot from other repositories or building from source, since the odds are this issue is not a bug in dovecot. I've just tried setting up the LMTP service and eventually uncovered that that the greeting the server responds with straight after connecting isn't being returned. This must be a configuration mistake on my behalf but I just haven't been able to figure it out yet. I haven't had LMTP configured for awhile but I'm sure I've had it all in place and don't recall any issue like this. I've followed the detail here http://wiki2.dovecot.org/LMTP, in particular # add lmtp to protocols, otherwise its listeners are ignored protocols = imap pop3 lmtp service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } unix_listener lmtp { #mode = 0666 } } What's also interesting, using telnet my first attempt to connect results in the server closing the connection immediately and then a second attempt to connect results in an established connection but no response from the server so that then the LMTP client knows it's all good to begin issuing commands. I have no idea about the architecture of dovecot and the LMTP service but it's as if dovecot has successfully bound to the port allocated for LMTP* but the the LMTP service has either not started or dovecot doesn't know which service to pass the connection on to. * - dovecot has definitely bound to the port (localhost:24) as netstat clearly shows this. I've tried enabling debug logging per the details here http://wiki2.dovecot.org/Logging and checked that I'm looking at all the logs I need to be using doveadm log find but not seeing any information that helps. At the moment I know I'm light on necessary detail for anyone to help but I thought I'd try in case anyone has seen this before and is able to tell me I've missed X and Y. I'm planning on setting up a clean environment to sort this issue out and if needed will follow up here with more detail and the final solution/s. Thanks Phillip

[Dovecot] mime support for pigeonhole
by Tim Dickson 06 Feb '14

06 Feb '14

is there any chance of rfc5703 (mime support/extension) being added to pigeonhole? I am trying to filter mail with .exe and .zip attachments, to no success. I have tried *header :contains "x-attached" [".zip", ".exe"] *but emails i'm getting don't have x-attached. a sample snippet is below. Subject: testa1 Content-Type: multipart/mixed; boundary="------------020304040002050407030900" This is a multi-part message in MIME format. --------------020304040002050407030900 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit this has a compressed file added a1 --------------020304040002050407030900 Content-Type: application/x-zip-compressed; name="pinglog.zip" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="pinglog.zip" I have tried *header :contains ["Content-Type","name","filename"] ["application/x-zip-compressed",".zip",".exe"]* but that doesn't work either. I can't use body because that doesn't include the mime headers, so the only way I can see is to use mime (aka rfc5703) I am using dovecot 2.1.8 with pigeonhole 0.3.3 (and am about to use dovecot 2.2.9 with pigeonhole 0.4.2 on another server) If I'm just missing the point, or there is already support, please point me in the right direction.

[Dovecot] Mail location security
by Roman Gelfand 06 Feb '14

06 Feb '14

I am not sure I understood this issue correctly... When using maildir with ie ldap. Suppose ldap attribute settings say gid 8 and uid 999, Those are the permissions for every email address. If so, someone who has access to one email user on the server, has access to all. If this is so, is using mailbox instead of maildir resolve this problem? Thanks in advance

[Dovecot] userdb section not recognized in dovecot.conf. Help?
by CypherPunk 06 Feb '14

06 Feb '14

I'm following a tutorial[1] on how to configure dovecot and the tutorial says to insert the following configuration options into the dovecot.conf file: disable_plaintext_auth = no mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u userdb { driver = passwd } This seems to have worked for a lot of others using this tutorial but not for me. When I try to start dovecot, I am told that the section at userdb is an unknown section type. I've spent the last few hours on Google searching this out and I've gotten conflicting answers that don't make sense. Is this the proper way to use the userdb directive? For information, I've also tried userdb{ driver = passwd-file } and that didn't work either. So I'm assuming that perhaps userdb is deprecated somehow but I don't know what to replace it with. Can someone point me in the right direction? Many Thanks! CypherPunk [1] https://www.digitalocean.com/community/articles/how-to-set-up-a-postfix-e-m…

[Dovecot] Debian Wheezy-Backports - Dovecot (1:2.2.9-1~bpo70+1) missing xz compression support?
by T.B. 05 Feb '14

05 Feb '14

Hallo Everyone, since some days a new dovecot version is available in Debian "wheezy-backports": (1:2.2.9-1~bpo70+1) wheezy-backports As described in http://wiki2.dovecot.org/Plugins/Zlib and http://www.dovecot.org/doc/NEWS-2.2 "xz"-compression is available since Dovecot version 2.2.9. Today I tried to convert my mailboxes with the new xz compression. Therfore I changed my config as follows: /etc/dovecot/conf.d/10-mail.conf: # Space separated list of plugins to load for all services. Plugins specific to IMAP, LDA, etc. are added to this list in their own .conf files. mail_plugins = zlib acl fts fts_solr /etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz # gz or bz2 or xy Now I tried to convert my mailboxes - but somehow, something goes wrong: root@SERVER:/# dovecot --version 2.2.9 root@SERVER:/# dsync mirror mdbox:/srv/converted_vmail/ doveadm(root): Error: zlib_save: Support not compiled in for handler: xz dsync(root): Error: zlib_save: Support not compiled in for handler: xz Where is the failure? Did the packet maintainer forget to activate xz? I can't find anything xz related in the debian package changelog: http://metadata.ftp-master.debian.org/changelogs//main/d/dovecot/dovecot_2.… Should I contact the Debian packet maintainer? http://packages.qa.debian.org/d/dovecot.html Best regards T.B.

[Dovecot] How to archive mails on different server
by Anant Saraswat 05 Feb '14

05 Feb '14

Hi Guys, I want to make some new changes to my exim mail server So if any user archive his/her mail they will save on any other server not on Exim server , and whenever user want to search for any old mail he will go to archive folder and can search it from there.... So basically i want to setup a diffrent server for archiving and want to connect it to my Exim server. So whevever user archive his/her mail it will autometically save to diffrent server. So is it possible using any plugin , or something else . I am using Roundcube,Exim 4.72, Dovecot(LMTP). Regards, Anant Saraswat

Hi there, I've started work on a side project that I've been long wanting to do; better HTML archives of email. https://github.com/kaihendry/imap2json I'm just designing the JSON schema atm, and I thought it would be good to get your feedback (Esp Timo) before I make a horrible mistake. https://github.com/kaihendry/imap2json/blob/master/JSON-design.mdwn Is it a good idea to base the id of a converation by the sha1sum of the first message for example? Any other tips or words of encouragement would be great. Kind regards,

[Dovecot] Applying a DNS RBL to deny authentication?
by Marc Perkel 05 Feb '14

05 Feb '14

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication. We do front end spam filtering for thousands of domains and I decided to advertize authentication where there is none and I accept and blackhole all authenticated email to those servers. I have harvested the IP addresses in this list that is available through an RBL. It seems to me that a nice dovecot feature would be the ability to do a black list check against IP addresses connecting and deny access if listed. Thoughts?

[Dovecot] dsync backup; compressed to uncompressed
by Michael Smith (DF) 05 Feb '14

05 Feb '14

I need to backup some of the mailboxes on our system. We are currently using mdbox with zlib compression plugin. The backups need to be maildir without compression. How can I accomplish this using dsync? The following just causes each msg file in maildir to be compressed as well. dsync -f -u user1 backup maildir:/var/tmp/user1 While this just causes the dsync to fail while spewing a bunch of errors because it can no longer read the compressed mdbox files. dsync -f -u user1 -o mail_plugins= backup maildir:/var/tmp/user1 # doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_debug_passwords = yes auth_default_realm = domain1.net auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot-debug.log disable_plaintext_auth = no dotlock_use_excl = no lda_mailbox_autocreate = yes lock_method = dotlock mail_access_groups = mail mail_debug = yes mail_fsync = always mail_location = mdbox:~/mail:INDEX=~/index mail_plugins = quota zlib mail_privileged_group = mail 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 mbox_read_locks = dotlock mbox_write_locks = dotlock mdbox_rotate_interval = 1 weeks mdbox_rotate_size = 20 M mmap_disable = yes namespace { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Drafts autosubscribe4 = Sent autosubscribe5 = INBOX mail_max_userip_connections = 10 managesieve_max_line_length = 65536 quota = dict:User quota::file:%h/dovecot.quota quota2_rule = Trash:storage=+10%% quota3_rule = Junk:storage=+20%% quota_rule = *:storage=100M:messages=100000 recipient_delimiter = + sieve_before = /var/opt/mail/global.sieve/ zlib_save = gz zlib_save_level = 9 } pop3_reuse_xuidl = yes protocols = imap pop3 sieve lmtp service auth { inet_listener auth { port = 113 } unix_listener auth-userdb { user = nobody } } service lmtp { inet_listener lmtp { port = 24 } process_min_avail = 10 service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota zlib sieve } protocol imap { mail_plugins = quota zlib imap_quota } protocol sieve { mail_max_userip_connections = 10 mail_plugins = quota zlib managesieve_max_line_length = 65536 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 } protocol lmtp { mail_plugins = quota zlib sieve }

[Dovecot] BLF-CRYPT passwords
by KT Walrus 04 Feb '14

04 Feb '14

I’m using the Dovecot Enterprise Edition on Centos 6.5, but Blowfish password hashes don’t seem to work. What can I do to enable Blowfish hashes for passwords? Maybe I don’t have my installation configured properly? Note that I really want to use the existing Blowfish hashes in my MySQL database for Dovecot Authentication. The hashes are generated by PHP crypt() that has Blowfish support built-in. I looked at PHP’s sources, and PHP uses crypt_blowfish.c from http://www.openwall.com/crypt/. This code is in the public domain and could easily be used by Dovecot to support Blowfish passwords on all platforms (if Dovecot doesn’t already support Blowfish on all platforms). Kevin

Hello, i try to run the mail system which explain dovecot in the wiki. http://wiki2.dovecot.org/HowTo/VirtualUserFlatFilesPostfix I have that complete write in the config, only the domain and user settings i changed.

[Dovecot] mail_log_events, but who exactly triggered events?
by Arkadiusz Miśkiewicz 04 Feb '14

04 Feb '14

Hi. mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox. One of them deletes email and I'm logging delete related events. The only logged thing is: dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230 which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time) How to solve this problem? Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

[Dovecot] zlib unexpected EOF
by Anand Kumria 04 Feb '14

04 Feb '14

Hi, I am seeing occasional log entries like: Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Error: read(<imap client>) failed: zlib.read(<imap client>): unexpected EOF at 894774 Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Disconnected in APPEND (1 msgs, 201 secs, 0/5180550 bytes) in=894774 out=643701 I've been able to correlate this to users - using Thunderbird - complaining that they have been unable to "send email". Is the problem on the Dovecot side, their side or something else? If on the Dovecot any pointers and what I should look at? Thanks, Anand

Hello! I need to configure Quota on Roundcubemail with Dovecot2. So, I did: 90-quota.conf: # SQL backend: quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=20M:messages=1000 } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } OK, works! but, My webmail shows me 20M of quota. But on my Postfixadmin I configured 200M. How can I fix this? Att; *Lucas Possamai* http://about.me/lucaspossamai https://www.digitalocean.com/?refcode=25021cb7dbdf

[Dovecot] Assertion failed with imapc after upgrading Dovecot from 2.1.7 to 2.2.9
by Sylvain 29 Jan '14

29 Jan '14

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with Dovecot/imapc. I use Debian Wheezy (stable) which package Dovecot in version 2.1.7. I have tested the upgrade to Debian Jessie (testing) which package Dovecot in version 2.2.9 but an assertion is thrown : dovecot: imap(xxx): Panic: file imapc-list.c: line 499 (imapc_list_delete_unused_indexes): assertion failed: (strncmp(vname, fs_list->ns->prefix, fs_list->ns->prefix_len) == 0) I have checked source code and have seen that if *imapc_list_prefix* is not set, assertion will not be "walked". It's works but special inbox aren't detected correctly in email clients. If I understand the meaning of *vname* variable, it is because our Courier IMAP send us "INBOX" which is the value of my *imapc_list_prefix* and thus, assertion is thrown.

[Dovecot] Shared mailbox ACL
by Alex Ferrara 29 Jan '14

29 Jan '14

Hi everyone, I am having some trouble with shared folders in trying to replicate how we use them with a Cyrus backend. The auth database is Samba4 active directory, so I am using an LDAP lookup to authenticate and forcing the UID and GID to be all the same. I have a post-login script that sets the group ACL, and this seems to be working fine. /mnt/mail is an NFS mount to a FreeNAS machine, and there is only one Dovecot server connecting to that NFS share. I have been able to get the inbox of the shared mailbox to appear in Thunderbird, but I would like to allow all subfolders to have the same ACLs. Is there a way to do this without having an ACL entry for each folder in the dovecot-acl file? I also cannot seem to create folders under the shared inbox. Thanks. Below is the output of /mnt/mail/acl/shared-mailboxes shared/shared-boxes/group/accounting/accounting 1 shared/shared-boxes/group/team1/team1 1 shared/shared-boxes/group/team2/team2 1 Below is the output of dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-22-pve x86_64 Debian 7.3 nfs auth_mechanisms = plain login auth_username_format = %n mail_debug = yes mail_location = maildir:/mnt/mail/mailboxes/%n/Maildir:INDEX=/var/local/dovecot-indexes/%n mail_plugins = acl mail_shared_explicit_inbox = no managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { list = yes location = maildir:/mnt/mail/mailboxes/%%n/Maildir:INDEX=/var/local/dovecot-shared/%%n prefix = ZGroup/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_defaults_from_inbox = yes acl_shared_dict = file:/mnt/mail/acl/shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-postlogin { executable = script-login /usr/local/bin/postlogin.py user = vmail } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = acl imap_acl }

Oh yes, that's right. I confused maildir format with sendmail queue files that separates header and body. There is still some similarlity for mass mailouts to the same mail domain: they will have almost identical headers +/- message IDs and a few bytes here and there, but as you say, SiS is the way to go for deduping bulky message attachments.

[Dovecot] recipient_delimiter -- feature request
by Andrew Ray 29 Jan '14

29 Jan '14

Hi, It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension(a)sample.com and test+extension(a)sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension(a)sample.com is valid. Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did).

[Dovecot] post-login scripting failing with "denied access to user" v2.1.7
by Frank 29 Jan '14

I am trying to have a default sieve rule for new mailboxes that can be edited by users using the round cube sieve plugin. It would actually be better executed when a new user is created but my postfixadmin runs on a separate machine so that's a bit tricky. The "sieve-default =" setting won't quite achieve what I want as I want users to be able to edit the default rule (to adjust SPAM level) Mail works fine before I add my post-login script to 10-master.conf ---------------------- service imap { # tell imap to do post-login lookup using a socket called "imap-postlogin" executable = imap imap-postlogin } service imap-postlogin { # all post-login scripts are executed via script-login binary executable = script-login /etc/dovecot/custom_sieve/postlogin.sh # the script process runs as the user specified here (v2.0.14+): user = mail # also tried $default_internal_user and root # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } After adding this setting, login fails and gives the error below. It certainly looks like a permission issue, but I have checked my script is executable and owned by vmail:vmail. The bash script executes fine as the mail user. The other possibility is that dovecot is denying access to the $HOME variable, but that seems unlikely. Nevertheless, I am stuck!
