[Dovecot] Public Folders for spam/nospam -> don't get it
by Denny Schierz 25 Oct '10

25 Oct '10

hi, Dovecot: 2.0.5 I want to use public folders (maildir), for my spam mails to feed spamassassin, but I don't get it working. My Evolution 2.28.3 (nothing else tested) can't subscribe the folders: namespace { hidden = no inbox = yes list = yes location = prefix = INBOX/ separator = / subscriptions = yes type = private } namespace { hidden = no inbox = no list = children location = maildir:/home/vmail/public:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } angelica:/etc/dovecot/conf.d# ls -l /home/vmail/public/ total 24 -rw-r--r-- 1 vmail vmail 11 Oct 23 14:14 dovecot-acl -rw------- 1 vmail vmail 45 Oct 23 13:56 dovecot-acl-list -rw------- 1 vmail vmail 48 Oct 24 19:22 dovecot.mailbox.log drwxr-xr-x 2 vmail vmail 4096 Oct 23 14:03 nospam drwxr-xr-x 2 vmail vmail 4096 Oct 23 14:03 spam -rw------- 1 vmail vmail 12 Oct 24 19:22 subscriptions # cat /home/vmail/public/dovecot-acl anyone lrp, also in subfolders spam/nospam I tested several configurations, but nothing works. Sometimes I can see the folders, but can't subscribe them (invalid/unknown namespace), sometime I don't see the folders ... does anyone has an answer for me ? cu denny

[Dovecot] Maildir filename extensions S=<size> and W=<vsize>
by Ralf Hildebrandt 25 Oct '10

25 Oct '10

I'd like to add S=<size> and W=<vsize> to the filenames in my Maildir storage for newly delivered mails. But I cannot find where I can make Dovecot's LDA add those. Anybody? http://wiki2.dovecot.org/MailboxFormat/Maildir says: A maildir filename with those fields would look something like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S which is exactly what I want, but it doesn't tell me how! -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] fallocate and glibc 2.10
by Paul Howarth 25 Oct '10

25 Oct '10

In glibc 2.10 (32 bit) fallocate() exists but fallocate64() doesn't. When _FILE_OFFSET_BITS==64, fallocate() is a redirect to fallocate64() and the program can't be linked (fails to find symbol fallocate64). See http://bugzilla.redhat.com/500487 Attached patch detects fallocate() more robustly to guard against this problem. Cheers, Paul.

[Dovecot] "Maintenance instance"

Does any of you have a "Maintenance instance" of dovecot? Something that will accept any user/pass combination (and thus doesn't make MUAs fail in utter unforeseen ways), and gives any user logging in a canned mail (e.g. "We're doing maintenance, go away") -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

24 Oct '10

Hi all, I have running dovecot-1.2.15 and I try whith dovecot-antispam-1.3 and 1.2-* if it's running for me. I use mailtrain backend to call a script when I move a mail to a specific folder. Then, I set allow_append_to_spam: yes At .config for Make dovecot-antispam. I set the plugin's name to: PLUGINNAME=isspam An then, I have another copy of the sources and .config with plugin's name set to: PLUGINNAME=nospam With this. If I put on dovecot.conf protocol imap { ... mail_plugins = isspam nospam ... } When I try to login, the connection is aborted and dovecot connection die with coredump Are there are any people with similar settings ?

[Dovecot] [stava@telcotec.se: [stava: antispam problem]]
by Lars Stavholm 24 Oct '10

24 Oct '10

Hi All, I've built the dovecot-antispam-plugin from hg.dovecot.org and installed it. I've turned on debugging with "mail_debug = yes" in dovecot.conf and restarted dovecot. However, the antispam plugin module gets loaded by dovecot, but then nothing, i.e. when moving mail from Inbox to Spam and vice versa, I see nothing. How do I get debug messages from the dovecot-antispam-plugin? There's a few i_debug() statements in there (and I added a few myself), but I don't see any of these messages. # dovecot -n # 2.0.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.7-0.4-desktop x86_64 openSUSE 11.3 (x86_64) auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes base_dir = /var/run/dovecot disable_plaintext_auth = no dotlock_use_excl = yes listen = * mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Mail:LAYOUT=fs mail_plugins = autocreate quota zlib managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date passdb { args = /etc/dovecot/ldap.conf driver = ldap } plugin { antispam_backend = dspam antispam_dspam_binary = /usr/sbin/dspam antispam_signature = X-DSPAM-Signature antispam_spam = Spam antispam_trash = Trash autocreate = Spam autocreate2 = Sent autocreate3 = Trash autosubscribe = Spam autosubscribe2 = Sent autosubscribe3 = Trash quota = fs:disk quota quota2 = fs:user quota } protocols = imap ssl = no userdb { args = /etc/dovecot/ldap.conf driver = ldap } verbose_ssl = yes protocol imap { mail_plugins = autocreate quota zlib imap_quota imap_zlib antispam } Any help appreciated /Lars Stavholm

[Dovecot] minimize mbox mdbox fragmentation
by Stan Hoeppner 22 Oct '10

22 Oct '10

Hi Timo, Any chance the mbox/mdbox writer code could be modified to do physical preallocation on files to help avoid file(system) fragmentation? Constantly appending a file is the prime recipe for causing fragmentation, and mbox is notorious for this--not a fault of Dovecot but the nature of the mbox beast. Obviously maildir doesn't have such a problem, but some (many?) of us still prefer mbox for many reasons, fast full body search being one, portability being another. mdbox file fragmentation could benefit from such a change as well. I was having a discussion on the XFS list about this, trying to tweak XFS mount options to mitigate the fragmentation effects. Alas, there is no way to do this purely at the filesystem level. From Dave Chinner, one of the lead XFS devs: "What you want is _physical_ preallocation, not speculative preallocation. i.e. look up XFS_IOC_RESVSP or FIEMAP so your application does _permanent_ preallocate past EOF. Alternatively, the filesystem will avoid the truncation on close() if the file has the APPEND attribute set and the application is writing via O_APPEND... The filesystem cannot do everything for you. Sometimes the application has to help...." How great would the effort need to be to implement something like this? Would the return on investment be sufficient to justify doing this, in your eyes? -- Stan

[Dovecot] Question about Client Certificates
by William Gallafent 21 Oct '10

21 Oct '10

Hi, I have a simple dovecot installation, version 1.2.12 of ubuntu 10.10. I also have a straightforward newbie question! I've hunted in the wiki and on the wider web, but not yet found a solution. Current status: I have successfully configured imap with tls, accessed on port 993, and for security require a valid client certificate to be presented, using ssl_require_client_cert and ssl_verify_client_cert. This is all working fine! Now I want to add a SquirrelMail service to the same server. This will connect using IMAP over port 143, without TLS. My question is: how do I achieve this! At the moment, I simply get the following in the logs: Aborted login (cert required, client didn't start TLS): method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured If I comment out the "ssl_require_client_cert = yes" in the auth default section, SquirrelMail then works fine … but I can also connect remotely without presenting a valid certificate, which is no good! At the moment I have a single auth section in dovecot.conf, the "auth default { ... }" section. I wondered if I need a second section, which does not have the ssl requirement inside it. Is that right? If so, how do I link one auth section to the imaps service, and the other to the imap service (listening only on localhost)? In other words, I want "ssl_require_client_cert = yes" for remote connections (on port 993), but "ssl_require_client_cert = no" for local connections using non-tls imap on port 143. Is this possible? Hope that late-night explanation makes sense, and hope somebody can point me in the right direction, thanks in advance! -- Bill Gallafent.

Hi, we found a serious bug while testing our migration scripts. in Solaris (or other system 5) the user variable is not always set. Dsync is not very happy about that and crashes with an segmentation fault. After hours of debugging and TWOE simple lines # USER=$LOGNAME # export USER the problem was solved! The null pointer was found - so i will go home now an drink a bottle of "Erdinger"... hope this hint helps for development - and we hope that we don't find more of these bugs :) bye Tobi -- Dr. Nagler & Company GmbH Hauptstraße 9 92253 Schnaittenbach Tel : 09622-7197-38 Fax : 09622-7197-50 Web : http://www.nagler-company.com E-Mail : tobias.daucher(a)nagler-company.com Hauptsitz: Schnaittenbach Handelregister: Amberg HRB 4653 Gerichtsstand: Amberg Steuernummer: 201/118/51825 USt.-ID-Nummer: DE 273143997 Geschäftsführer: Dr. Martin Nagler, Dr. Dr. Karl-Kuno Kunze

[Dovecot] allow_nets and local sockets
by Oliver Eales 21 Oct '10

21 Oct '10

Hello, i am running dovevot 2.0.5 using ldap authentication with the allow_nets paramter to limit access to some local networks. The problem is, when i want to use the local lmtp socket from postfix *virtual_transport = lmtp:unix:private/dovecot-lmtp * i get the follwing error: *Oct 21 15:48:03 auth: Info: passdb(username): allow_nets check failed: Remote IP not known *When using the TCP socket with postfix *virtual_transport = lmtp:localhost:30025 *it is working. (i have 127.0.0.0/8 in the allow_nets list) Is there a way, other than using two different config sets to get this working together ? Something like disabling the address lookup on local passdb sockets ? Regards, Oliver

[Dovecot] Director and CRAM-MD5

Hello, i have a setup with two director servers pointing to two backends. I don't care that much for load balancing, my main goal is high availability.

[Dovecot] Campo de quota en LDAP
by Antonio Perez-Aranda 20 Oct '10

20 Oct '10

En un principio, en los ldif que tenemos de los usuarios de prueba, tenemos el campo mailQuota. Sin embargo, si nos vamos a los schemas de qmail medianamente, con algo más de 3 años, se cambió mailQuota por mailQuotaSize y mailQuoatCount. Esto se debe entre otras cosas a que en la cabecera del fichero maildirsize del buzón, tenemos esta información, es decir, máximo tamaño ocupado y máximo número de mensajes. En el ldap de producción se sigue usando mailQuota? En el courier que tenemos montados aquí, misma versión y misma configuración que la existente en desbuz03, cuando no existe la quota del maildir directamente no da información sobre quota. ¿Estamos usando la quota de ldap? O al entregar un correo mediante Exim, se actualiza el fichero maildirsize con los valores de mailQuota. En este caso, podemos seguir con este comportamiento, o podemos utilizar la información que viene de ldap si no hay nada en el maildirsize.

We have custom plugins for squirrelmail which use thread orderedsubject, but according to capabilities dovecot only support thread by references algorithm. At present, we are using Courier with this capabilities (two algorithms are implemented). Could we use orderedsubject in dovecot?

[Dovecot] Outlook problem when deleting mails
by Ulf Jaenicke-Rößler 20 Oct '10

20 Oct '10

Hi, I'm seeking advice to solve the following "mystery": I set up an IMAP server on Ubuntu 10.04 (dovecot 1.2.9). It appears to work fine apart from one problem. A colleague is running Outlook 2007 on Vista and sometimes (sometimes very often, sometimes only occasionally) when he wants to delete mails, Outlook hangs for some time (he says about 1, 2 or 3 minutes) until it finally puts out a message box: "The server did not respond to this IMAP command before the connection was terminated" I have activated the outlook-idle workaround, but I learned that this doesn't do anything anymore, right? There's no error message in dovecot's logs. Nevertheless, today I found this around the time the error happened: 2010-10-12 17:13:02 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:13:03 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:15:07 IMAP(user): Info: Disconnected in IDLE bytes=272298/631645 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=63/539 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=462/47082 What exactly does "Disconnected in IDLE" mean? Could the error be related to the same time stamp? (I'm not yet sure, if it always happens this way if the error occurs) I also found "Disconnected in IDLE" for other users at other times, but no one other complained so far. Maybe, that's because most of the other users use Thunderbird ;-) Is this problem known? What could I do? Best regards Ulf

[Dovecot] (Single instance) attachment storage with single-dbox
by Timo Sirainen 19 Oct '10

19 Oct '10

Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this: With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. ..until someone goes and starts manually copying files or maybe restoring from backups or whatever, causing the hard links to be replaced with separate files having link count=1, even when there are other files pointing to the same attachment file. Now deleting this one mail will delete the attachment too early. I can't think of any other reasonable way to handle this though, so unless someon has some great ideas, I think the solution is to simply add enough warnings that message store shouldn't be accessed directly. Maybe add some import/export commands to doveadm which can be used to add a bunch of mails to storage without doing it directly on filesystem.

[Dovecot] gssapi problems (postfix sasl through dovecot, dovecot imap working fine)
by Trever L. Adams 19 Oct '10

19 Oct '10

Thanks to Timo, I have solved all but one of my problems. For back ground, I am using Samba4 as an AD. I have the userdb working from LDAP just fine and kerberos authenetication for dovecot's IMAP server working fine. The problem is using dovecot's SASL with postfix. I also have plain/login working in imap and smtp. Both use pam_krb5 through pam to authenticate clients that don't have kerberos, and for now smtp. When trying to do smtp kerberos, I get the following: postfix/smtpd[6197]: warning: CLIENT_FQDN[CLIENT_IP]: request longer than 2048: AUTH GSSAPI ... dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=SERVER_IP#011rip=CLIENT_IP#011secured#011resp=<hidden> dovecot: auth: Debug: gssapi(?,CLIENT_IP): Obtaining credentials for smtp@MAILSERVER_FQDN dovecot: auth: gssapi(?,CLIENT_IP): While processing incoming data: Unspecified GSS failure.

Any help would be greatly appreciated. I have made sure that the file has proper permissions. I have regenerated the smtp cert making suer the password is accurate. I have done everything I know to try. The only thing that I am guess remains is something is broken with Thunderbird's kerberos setup for smtp. Thank you very much, Trever

He all, I'm migrating a big system from Courier to Dovecot and we have a custom analyzer logger system to Courier logs. We have got the very similar specs on IMAP LOGIN log, but I can't get the Logout format. Courier write like that: ... imapd: LOGOUT, user=luism.martinez, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=131, sent=632, time=0 ¿Is there any Variables on imap_logout_format to get headers, body and time vars?

Hello Dovecot v2.0.5 zlib_save_level = 6 # 1..9 zlib_save = gz # or bz2 Is there a config option to disable zlib, even if above config are in place? If so please provide an example. If no, would it be possible to add one? Like if zlib_save_level = 0 disable zlib. So one can configure per mailbox compression level via sql database. KuiZ Thanks

Hello, another problem with changed separator (2.0.5-0~auto+23 (b8803a1e2dc2)).

As "user": 0 getacl "INBOX.test" * ACL "INBOX.test" "testuser" lrs "user" lrwstipekxacd 0 getacl "INBOX.test.test2" * ACL "INBOX.test.test2" "testuser" lrs "user" lrwstipekxacd (but also tested with more rights for testuser) As testuser with unchanged separator: 0 list "" "*" [includes:] * LIST (\Noselect \HasChildren) "." "INBOX.shared.user" * LIST (\HasChildren) "." "INBOX.shared.user.test" * LIST (\HasNoChildren) "." "INBOX.shared.user.test.test2" and 0 select INBOX.shared.lpmail.test.test2 works. As testuser with separator=^: 0 list "" "*" [includes:] * LIST (\Noselect \HasChildren) "^" "INBOX^shared^lpmail" * LIST (\HasNoChildren) "^" "INBOX^shared^lpmail^test" INBOX^shared^lpmail^test^test2 is missing. 0 select INBOX^shared^lpmail^test2 0 NO Mailbox doesn't exist: INBOX^shared^lpmail^test2 (also tested without having everything under INBOX).

[Dovecot] cmusieve and logging
by cool.chris65＠web.de 18 Oct '10

18 Oct '10

Hello, is there a way to write a logfile during sieve-actions? At least, I have trouble in reading sieve-scripts with tools from kmail ("connection refused) or thunderbird (timed out: server does not answer). There is no problem with the mailbox itself in reading or writing in it. The config for Sieve: dovecot.conf: ## ## LDA specific settings ## protocol lda { # Address to use when sending rejection mails. postmaster_address = christoph@localhost # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. #auth_socket_path = /var/run/dovecot/auth-master debug = yes log_path = /var/log/dovecot/dovecot-deliver-errors.log info_log_path = /var/log/dovecot/dovecot-deliver.log # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } plugin { # Here you can give some extra environment variables to mail processes. # This is mostly meant for passing parameters to plugins. %variable # expansion is done for all values. #sieve = /var/sieve-scripts/%u/sieve sieve=~/.dovecot.sieve # Quota plugin.

SQL) # maildir: Maildir++ quota # fs: Read-only support for filesystem quota #quota = maildir # ACL plugin. vfile backend reads ACLs from "dovecot-acl" file from maildir # directory. You can also optionally give a global ACL directory path where # ACLs are applied to all users' mailboxes. The global ACL directory contains # one file for each mailbox, eg. INBOX or sub.mailbox. #acl = vfile:/etc/dovecot-acls # Convert plugin. If set, specifies the source storage path which is # converted to destination storage (mail_location) when the user logs in. # The existing mail directory is renamed to <dir>-converted. #convert_mail = mbox:%h/mail # Skip mailboxes which we can't open successfully instead of aborting. #convert_skip_broken_mailboxes = no # Trash plugin.

Currently works only with maildirs. When a user # expunges mails, the mails are moved to a mailbox in another namespace # (1st).

[Dovecot] After Upgrade to Dovecot 2.0.5 SSL problems
by derunfehlbare＠freenet.de 18 Oct '10

18 Oct '10

Hi, I've upgraded my Dovecot from 1.2 to 2.0.5. Everything is working fine on my Gentoo, also login with imaps and pop3s. But: I have in my config autocreate folders for new users. After creating a new user (with PostfixAdmin) I see in my logfile with SSL enabled this: imap-login: Warning: SSL alert: where=0x4004, ret=560: fatal unknown CA [127.0.0.1] With SSL-disable, autocreation folders for new users is no problem. I've searched a fiew days for a solution, but I did not find anything. Also dovecot-page what describes running SSL does not help me. Here are the relevant config-sniplets: plugin { autocreate = Trash autocreate2 = Sent autocreate3 = Junk autocreate4 = Drafts autosubscribe = Trash autosubscribe2 = Sent autosubscribe3 = Junk autosubscribe4 = Drafts } service imap-login { inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } } ssl = yes ssl = yes ssl_cert =

[Dovecot] Backup recovery with mdbox
by Andre Nathan 18 Oct '10

18 Oct '10

Hello I'm using mdbox for mail storage. I'd like to give users an option to recover backups into a new folder, say, Backup-$date. Is there a simple way to do this? I was looking at tools like dsync and doveadm-altmove but apparently they're not intended for this kind of stuff. Thanks in advance, Andre

I'm concerned with the very same question. I currently have 1.2.12 running very well and I see risk in an upgrade to ver 2.x. Unless of course the benefits outweigh the risks. I have been carefully watching the ver 2.x tree rev from week to week and I await the defacto signal from people that it is in fact at least as solid at 1.2.12, that signal being adoption by people in busy mail servers. So therefore I await ver 2.0.6 with a mix of conflicting anticipation and trepidation. :-) -- Dennis Clarke dclarke(a)opensolaris.ca <- Email related to the open source Solaris dclarke(a)blastwave.org <- Email related to open source for Solaris

There is still a rather large number of Solaris 8 Sparc servers out there running in production and based on the conversations I have had with some sysadmins they will upgrade them when the smoke comes out. That could be another five years. So, before you say "stability has less to do with that" you should see the horrendous work it takes to port an app from the open source world ( usually Linux people with tons of Linux-isms/GCC-isms in it ) over to an old POSIX/XPG4 ( POSIX.1-1990, POSIX.2-1992, POSIX.1b-1993, POSIX.1c-1996 etc ) compliant UNIX.

Hi all, Is possible to split dovecot.conf with a very very big plugin {} section? Maybe, some like apache with sites-enabled.d Then, we could have a file per plugin.

[Dovecot] Version checks and API/ABI/sonames
by Axel Thimm 18 Oct '10

18 Oct '10

Hi, pigeonhole/sieve check against dovecot's version comparing to what they have been built against. This means that whenever there is a minor version of dovecot released pigeonhole/sieve need to be rebuilt and then redistributed to users even if there is no need for it (I'm thinking of packaged versions of dovecot and dovecot-pigeonhole). Could the checks become ABI-version aware, so that rebuilds and redistribution are kept to a minimum? Maybe Timo is already keeping API/ABI stability between minor updates, so the version checks should be against the first two version components only. Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] Retrieving unread message count
by Brandon Davidson 18 Oct '10

18 Oct '10

Timo, I'm working with a webmail client that periodically polls unread message counts for a list of folders. It currently does this by doing a LIST or LSUB and then iterating across all of the folders, running a SEARCH ALL UNSEEN, and counting the resulting UID list. Eventually I'd like to see it using RFC5819 LIST-EXTENDED, but that requires a fair bit of work. In the mean time I'm trying to speed up the existing iteration. I've got it working using 'STATUS "mailbox" (UNSEEN)', but the language in RFC3501 suggest that this may be slow. There is a counterproposal to use RFC4731 ESEARCH and do 'SELECT "MAILBOX"'; 'SEARCH RETURN (COUNT) UNSEEN'. >From an IMAP server perspective, which do you anticipate would be faster? >From a client perspective it seems like STATUS would be better since it involves less round-trips to the server and less output parsing, but given the warnings in the RFCs there is concern that it is in fact be more expensive. -Brad

Huh? What are you talking about? If dovecot has tcpwrapper support and is compiled -DTCPWRAP then it can run as a standalone daemon and will consult the hosts.allow/deny files, no need for inetd of any type. man 3 hosts_access man 5 hosts_access for details on tuning. Tcpwrapper tuning is far more powerful than people realise.

[Dovecot] strange behavior with virtual accounts and imap
by vladi 18 Oct '10

18 Oct '10

hi, I've recently setup new mailserver with dovecot and postfix. They use mysql and virtual accounts. All works perfectly except.. There is one group account named info, all the mail is forwarded to every other account. Users download their mail via Outlook (2003, 2007) with imap. If someone downloads email send to info and delete it after that. Outlook stoke the message and doesn't delete it immediately, thats normal. But if later someone else downloads his mail and it have received the same letter to info. The message appear as if it's already deleted by that user. But is supposed to be unreaded. I cant find any info why is this happening. Please help

[Dovecot] quota sql dict permissions dilemma
by LEVAI Daniel 18 Oct '10

18 Oct '10

Hi! I'm trying to set up SQL based dict quota. The quota is working, gets updated but I had to configure really loose file permission to make it work: dovecot.conf: dict { quota = pgsql:/etc/dovecot/dovecot_dict-sql.conf } service dict { unix_listener dict { mode = 0660 group = vmail # sidenote: I noticed that writing the number equivalent # of 'vmail' here does not work. Why? } } # ~ls -la /etc/dovecot/dovecot_dict-sql.conf -rw-r----- root vmail dovecot_dict-sql.conf # ~ls -la /var/dovecot/dict srw-rw---- root vmail /var/dovecot/dict= Every virtual user lookup returns a 'gid' field, and it is always 'vmail' (actually it is the number equivalent of 'vmail'). Despite that the imap process should run as the 'uid' and 'gid' values returned from the userdb, it can not read the dict config file: dovecot.log: dict: Error: Can't open configuration file /etc/dovecot/dovecot_dict-sql.conf: Permission denied dict: Error: Failed to initialize dictionary 'quota' lda(<username>): Error: read(/var/dovecot//dict) failed: Remote disconnected Now I must set o+r to the config file, which I really don't want to, given that it contains the db username and password. Strange thing is that the group r/w permission is enough for the dict= socket, and it doesn't need world-wide permissions at all.
