Re: [Dovecot] Virtual folder for selected users only? (1.2.15)
by Sebastian Schäfer 19 Feb '14

> thats very outdated, you should upgrade 2.1.x / 2.2.x latest I would like to avoid this, because the 1.2.15 is running extremely stable for a long time. (also it's the most recent version on this old squeeze-machine if not using backports) As far as I see, the virtual folders are fully supported since 1.2.x - am I wrong? What are the advantages of upgrading to 2.x? Are there security issues? Thanks! best, sebastian

[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

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

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.

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.
