[Dovecot] Plugin "lazy_expunge" and subfolder
by Andreas Kossack 28 Sep '12

28 Sep '12

Hi Timo, hi all, we want to use the "lazy_expunge" plugin (from dovecot 2.1.10) and had configured it in a test environemnt like described in "http://wiki2.dovecot.org/Plugins/Lazyexpunge" (1 namespace) There are some subfolders from "INBOX" (like "INBOX/SPAM") in a "maildir++" configuration. All actions on first level directories ".INBOX", ."Sent" or ".Archives" are working as expected. If there is an expunge activity on e.g. ".INBOX.SPAM" directory we get an error message in dovecot log: Sep 26 12:27:55 imap(testuser): Error: lazy_expunge: Couldn't open expunge mailbox: Character not allowed in mailbox name: '.' What can we do or change to make it work? -- Best regards A.

[Dovecot] sieve vacation
by Bob Miller 27 Sep '12

27 Sep '12

Hello, I set up pigeonhole on a server and am using roundcube's sieverules to create a set of rules. When using the vacation feature, I can see in the logs that dovecot is sending the vacation response, but the recipient never receives it. What method does dovecot use to send the response? Does it use the sendmail binary, does it use the mail command, does it connect to some smtp server somewhere, does it use qmail-inject if it finds it? I find no evidence it is using any of these methods on my server, but I am not sure if one of these methods is failing or if there is some place else I should be looking for the missing vacation response... Thank you for any suggestions... -- Computerisms Bob Miller 867-334-7117 / 867 633 3760 http://computerisms.ca

[Dovecot] with mbox format doveadm ignores subfolders of inbox
by Jürgen Obermann 27 Sep '12

27 Sep '12

Hello. After we switched the format from mbox to mdbox on our dovecot (version 2.1.9) servers last week, some of our users were missing the subfolders of their inboxes. So far we thought that with the mbox format it is not possible to have mail folders containing both messages and subfolders. Now we know that there is one exception from this rule: the inbox. With mbox format dovecot supports subfolders of the inbox, and a few of our users actually detected and used this feature! Internally the messages are stored in /var/mail/user or in a file named 'inbox' and the subfolders are in the directory 'INBOX'. (The OS is case sensitiv.) The problem was that doveadm and dsync do not support subfolders of the inbox and therefore these folders did not get synchronized from our old mbox server to the new mdbox dovecot server. The command doveadm -o mail_location=mbox:~user123/Mail mailbox list -u user123 '*' did not show any subfolder of INBOX, whereas the the following with a wrong mail_location showed that there are subfolders of INBOX doveadm -o mail_location=mbox:~user123 mailbox list -u user123 '*' Finally we could import the missing subfolders one after one in the mdbox server with commands like this: doveadm import -u user123 mbox:~user123/Mail "" mailbox INBOX/subfolder all It would be nice if doveadm could be changed to not overlook subfolders of the inbox with mbox format.

[Dovecot] Changing Quota downward for special Mailboxes? (2.1.6)
by Jost Krieger 27 Sep '12

27 Sep '12

It seems there is no way to correct te quota limit downward for some mailboxes, like: quota_rule9 = UCE-TMP:storage=-10%% The idea is to not eat up the users storage with spam, so that spam stays in the queue (for some time) while real mail gets delivered. There *is* a line } else if (*value != '-' && relative_rule) { in quota.c, but nothing else handles it, starting with quota_rule_parse_percentage.

[Dovecot] 76Gb to 146Gb
by Spyros Tsiolis 27 Sep '12

27 Sep '12

Hello all, I have a DL360 G4 1U server that does a wonderfull job with dovecot horde, Xmail and OpenLDAP for a company and serving about 40 acouunts. The machine is wonderful. I am very happy with it. However, I am running out of disk space. It has two times 76Gb Drives in RAID1 (disk mirroring) and the capacity has reached 82%. I am starting of getting nervous. Does anyone know of a painless way to migrate the entire contents directly to another pair of 146Gb SCSI RAID1 disks ? I thought of downtime and using clonezilla, but my last experience with it was questionable. I remember having problems declaring disk re-sizing from the smaller capacity drives to the larger ones.

[Dovecot] second dovecot imap server
by Spyros Tsiolis 27 Sep '12

27 Sep '12

Hello again all, I would like to thank everyone for rushing to help me with the dovecot migration issue. I am , currently, reading and studying what has been said by all the good and kind people who responded to this list. OK, on the same issue,I thought of adding a totally new server with dovecot acting as a secondary/backup server for the mail servicing. Would that be possible ? What if I manage to make it work; Can I retire the old(er) server ? I would think that this is more on-topic than my last post. If I am out of line again, please respond in private. Thank you all! spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] duplicate all emails for 'backup' after user deletes them?
by Voytek Eymont 26 Sep '12

26 Sep '12

I have a user who occasionally reads, then deletes emails using his phone, on his and others email accounts, causing emails deleted on mail server, then he says 'oops, can you recover emails I've deleted?' what's the best way to duplicate all emails to duplicate accounts ? backup folders ? so, next time he deletes emails they can be 'recovered' on the server ? I was thinking along the lines of duplicating ALL emails...? any tips and pointers appreciated -- Voytek

I'm going to bring it back on topic. To recap the issue: 1. 73GB volume, ~82% full. Volume contains OS, spool, and mailboxes 2. Two 146GB drives on hand that are impossible to employ in either a live or offline migration due to hardware limitations--drive slots (0.82*73GB=60GB)-5GB(OS)= ~55GB/40= ~1.375GB/user mailbox (This math assumes the box has already been scoured and things like source files and other temporary stuff has already been removed, along with anything and everything not necessary to the primary functions of this box) 1.375GB/user suggests these users seem to horde old emails, or simply don't keep their mailboxes tidy. Normally I'd guess that a lot of space in a situation like this is taken up by full text search indexes, but you don't appear to have these enabled. I notice in your 'dovecot -n' output that you are already employing zlib, but to what degree is currently unknown to the list. Are you compressing maildirs with a nightly script? If not, and you're compressing on an ad hoc basis, realtime compression during write could save you quite a bit of additional space, extending the operating life of your current drives. Of course a simple request to your users to clean up their mailboxes would surely help as well, if that's a possibility--some users would flog one for making such a suggestion. If you're not fully taking advantage of compression currently, you may want to consider upgrading to Dovecot 2.x which allows transparent compression to dbox and maildir storage. You may want to migrate to mdbox message store format while still using zlib, and enable single instance attachment storage (SIS). As the name suggests, SIS saves an attachment only once, regardless how many user emails in which it exists. See: http://wiki2.dovecot.org/Plugins/Zlib I'd point you to the docs for SIS but I'm unable to find them in the Wiki. Surely someone else can provide the settings and/or update the wiki. -- Stan

[Dovecot] Can`t get over 1024 processes on FreeBSD - possible bug?

Hello, I still cannot get dovecot running with more then 1000 processes, but hard limit is 8192 per user in box.

[Dovecot] Traffic Accounting
by M. Naumann 24 Sep '12

24 Sep '12

Hi, I'm trying to find out how to do traffic accounting with Dovecot 2.x, preferrably v2.0.9, preferrably on CentOS 6. I've previously asked on IRC, but there was little feedback, and my understanding is now this list is the preferred media for such inquiries. If I recall correctly, some weeks ago I was told that traffic accounting is not officially supported on Dovecot 2, but that there could still be ways to get it to work, but no details were provided. I can think of the following approaches: * rawlog, preferrably piped (if that's possible?) into something like wc to prevent privacy issues and to reduce the I/O overhead * maildrop filtering in front of dovecot LDA (for mail inbound to mail storage) * sieve filtering Unfortunately I have little experience with either so far, so it's hard to make a good choice. I would appreciate hints on these approaches, and on any other approaches you can think of, as well as any related documentation / how-to you could point me to. While I'm subscribed to the list (for mail authentication purposes), I've disabled receiving any e-mail form the list, so please CC me on any replies. Thanks in advance, Moritz

[Dovecot] Sieve as mail client?
by Tom Horsley 23 Sep '12

23 Sep '12

A slightly off topic question, but maybe someone here has seen something like this: I want a program that operates entirely on the client side of an IMAP server, and implements the sieve filtering language by doing the necessary client side operations to move mail on the IMAP server, expunge mail, etc. It would also act as a proxy between my real mail client and the IMAP server so I'd never see any mail that hasn't been filtered first. The benefits are obvious: I could finally get sieve filtering on my stupid corporate exchange mail server :-).

[Dovecot] Dovecot 1.2.11 panic in mail-transaction-log-view?
by Michael Durket 22 Sep '12

22 Sep '12

I'm seeing this periodically in my logs for a specific user (followed by a backtrace which I've deleted from this post): Panic: file dovecot-1.2.11/src/lib-index/mail-transaction-log-view.c: line 290 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || max_file_seq != view->head->hdr.file_seq || max_file_offset != (uoff_t)-1 || min_file_offset <= view->head->sync_offset) Is there something I can do to work around this problem for the user, or is this something new and I need to follow the instructions at http://dovecot.org/bugreport.html to send in a bug report?

[Dovecot] thunderbird does not copy a tree-structure to dovecot imap
by Anton 22 Sep '12

22 Sep '12

Hi, running in problems with KMail I decided to switch to dovecot-imap & thunderbird on my kubuntu 12.04 64 bit (so I can read my imap-folder-mails with KMail again if it gets more stable) What I did: - I wrote a python script to convert my KMail mails folder to a thunderbird mailfolder (directory tree containing mbox files and *.sbd folders) - I created a fake pop mail account in thunderbird and imported the whole mail-structure (i just copied it) - I create a local imap account ( so I have a ~/Maildir dovecot folder in my user dir) - In /etc/dovecot: 1. /etc/dovecot/10-mail.conf (line 10) I set: mail_location = maildir:~/Maildir:LAYOUT=fs 2. /etc/dovecot/20-imap.conf (line 57) I set: imap_client_workarounds = tb-extra-mailbox-sep Now I want to copy the whole mailstructure from my imported fake pop mailfolder to the dovecot imap folder. What happens: Lets say my source structure is mailfolder1 + mail1 + mail2 + subMailFolder2 + mail1-in-subMailFolder2 + mail2-in-subMailFolder2 + subSubMailFolder3 + mail1-in-subMailFolder3 + mail2-in-subMailFolder3 I thunderbird (version 15) I drag and drop my mailFolder1 to the imap folder and I get: mailfolder1 + mail1 + mail2 + subMailFolder2 + subSubMailFolder3 as you See only the mails of the *TOP* folder are copied. All subfolders are created but they contain NO MAILS. Did somebody experience the same problem??? Otherwise I will write a python script to do that (I dont hope to need to write a mailclient in python ;-) ) Any hint is greatly welcome. Anton

[Dovecot] key -> object mailstore
by Damien Churchill 21 Sep '12

21 Sep '12

Hi, I was wondering what would be entailed in modifying dovecot 2.2 to support storing mail in an object store. I've seen a few mails dotted around in the ML history about supporting such a thing and seen it's basically dependant upon some changes in lib-storage to support writing messages without locking. Is this still the case? Regards, Damien

[Dovecot] Trouble implementing Antispam plug-in for Dovecot
by Ben Johnson 21 Sep '12

21 Sep '12

Hello, I am attempting to use the Antispam plug-in for Dovecot and am having trouble with the implementation. My configuration is Dovecot (1.2.9) + Sieve + SpamAssassin on Ubuntu 10.04. Mail that SpamAssassin tags as SPAM is moved into the affected user's "Junk" folder (/var/vmail/example.com/user/Maildir/.Junk). I followed the Wiki article at http://wiki2.dovecot.org/Plugins/Antispam . After restarting Dovecot, my IMAP client (Thunderbird v15) reports the following whenever I attempt to move mail from Inbox to "Junk" directory: "[CANNOT] antispam plugin not configured" That exact phrase appears only once in a Google search ( http://dovecot-antispam.sourcearchive.com/documentation/1.1plus-p20090218.g… ): if (!hamaddr || !spamaddr) { mail_storage_set_error(t->box->storage, ME(NOTPOSSIBLE) "antispam plugin not configured"); return -1; } Based on the surrounding source code, which I realize may be old, it seems that Ham and Spam addresses are required, or similar. I am using the following configuration options: /etc/dovecot/dovecot.conf -------------------- ## IMAP specific settings protocol imap { mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_plugins = quota imap_quota antispam } # [...] plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_pipe_program = /usr/bin/sa-learn-pipe.sh antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_spam_pattern_ignorecase = spam;junk } -------------------- For what it's worth, the logging directives seem not to have any effect (and perhaps the rest of the directives do not, either, hence the problem I'm having). I tried changing the above directives to their older directive names (I also changed the order slightly, which may be irrelevant): -------------------- plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_mail_spam = --spam antispam_mail_notspam = --ham antispam_mail_sendmail = /usr/bin/sa-learn-pipe.sh antispam_spam_pattern_ignorecase = spam;junk } -------------------- This changed the message in my IMAP client, when attempting to move a message from my Inbox to the Junk folder, to: "[SERVERBUG] failed to send mail" Does this indicate a problem with the "/usr/bin/sa-learn-pipe.sh" script that is provided on the Wiki (cited above)? Also, it was not clear from the documentation ( http://johannes.sipsolutions.net/files/antispam.html ) whether or not the Pipe back-end requires the X-DSPAM-Signature header, and if so, to what value it should be set when using SpamAssassin. Thanks for any pointers, -Ben

[Dovecot] Wrong quota calculation
by Cibest ML 20 Sep '12

20 Sep '12

Hi, We've a strange quota behavior on our dovecot servers. It seems that it's somehow doubling the real used storage (or could be something like twice the inbox size + size of other folders, hard to know for sure). It was initial setup with the maildir++ system. Now it's been configured with dict and mysql table but the result is the same. Dovecot version : 2.1.7 (from squeeze-backports). Maildir format is used As example, let's use mailbox(a)domain.com. If I check in the quota table, I'll find : - size : 697151354 - number of files : 1510 Now if I check the Maildir folder on the filesystem, I'll find : - size : 347960000 - number of files : 824 (using find . -type f|grep -v dovecot|wc -l, not 100% accurate) Another mail box Reported by dovecot : 503446986 1081 Filesystem : 248592000 598 Does anyone has an idea of what could be possibly wrong. We've checked & double-checked everything and nothing seems to be wrong (no dsync used). -- Regards Sébastien

[Dovecot] v2.1.10 released
by Timo Sirainen 20 Sep '12

20 Sep '12

http://dovecot.org/releases/2.1/dovecot-2.1.10.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.10.tar.gz.sig The director bugfix is pretty important at least when running in two director setups, since it can break the directors until both of them are manually shut down. I'm not entirely sure if the same happens in >2 director setups, but I'd think so (although I do wonder why I haven't seen it happen in them). BTW. I'm hoping for v2.2.alpha1 release within a week or two and to get it stabilized rather quickly. + imap: Implemented THREAD=ORDEREDSUBJECT extension. + Added "doveadm exec" command to easily execute commands from libexec_dir, e.g. "doveadm exec imap -u user@domain" + Added "doveadm copy" command. + doveadm copy/move: Added optional user parameter to specify the source username. This allows easily copying mails between different users. + Added namespace { disabled } setting to quickly enable/disable namespaces. This is especially useful when its value is returned by userdb. + Added mailbox_alias plugin. It allows creating mailbox aliases using symlinks. + imapc storage: Added imapc_max_idle_time setting to force activity on connection. + fts-solr: Expunging multiple messages is now faster. - director: In some conditions director may have disconnected from another director (without logging about it), thinking it was sending invalid data. - imap: Various fixes to listing mailboxes. - pop3-migration plugin: Avoid disconnection from POP3 server due to idling. - login processes crashed if there were a lot of local {} or remote {} settings blocks.

Re: [Dovecot] Prevent Download messages from server
by Peter Mogensen 20 Sep '12

20 Sep '12

> we have no problem, just i want to learn how can i do that. i think > it's clear . Well... I'm pretty sure most others don't. But anyway. As in ALL Internet protocols (IMAP being no exception), letting the client read data on the server requires it to download the data. Preventing download will prevent reading the mail. Period. So if you're fine with that and just want to learn how to do it, then just disable the account in the user database. /Peter

It uses the variant defining the largest allowed content size. I choose 1024 bit (128 Byte), since that is what most of the SHA-3 candidates use, so it's hopefully somewhat future proof. It's also rebased to the current head and switches the hmac uses added since the last version over to the changed API. It also fixes an "interesting" compiler warning I got with clang, which complained about the fact that struct hmac_context* was (re)declared in the prototype of hmac_md5_get_cram_context() and therefore separate from the one declared in hmac.h.

[Dovecot] Proxy connection timeouts

[Dovecot] Mailbox aliases
by Timo Sirainen 18 Sep '12

18 Sep '12

I've been wondering about ways to handle all the various different Sent/Sent Messages/Sent Items/etc mailboxes that different clients create and if there could be a way to make them work at least somewhat better. I'm mainly thinking about ISP-like installations where users are using tons of different clients and there's no way to get everyone configured properly. Of course the eventual solution is hopefully that all the clients will support SPECIAL-USE extension, but while waiting for that maybe mailbox aliases could help some. So one possibility would be to force autocreation of wanted specific mailbox names, and create aliases for the other commonly used mailboxes. The main difference here for the current behavior is that all of the mailboxes would contain the same mails, instead of different mails going to different mailboxes with different clients. So for example: .. mailbox Sent { auto = create special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent alias_for = Sent } .. If "Sent Messages" doesn't exist: - DELETE Sent works as usual - RENAME Sent works as usual If "Sent Messages" is created: - it's symlinked to Sent - DELETE "Sent messages" deletes the symlink, not the contents - RENAME "Sent messages" isn't allowed - DELETE/RENAME Sent fails with message: Delete/Rename for Sent not allowed before "Sent Messages" is deleted. Thoughts? The main disadvantage is that clients would still see two different mailboxes, and some would download contents from both of them. I was thinking about creating some wiki page which could list the best working configurations and also a client list, which would specify if it supports SPECIAL-USE and what the default mailbox names it uses are.

[Dovecot] Released Pigeonhole v0.3.2 for Dovecot v2.1.9
by Stephan Bosch 18 Sep '12

18 Sep '12

Hello Dovecot users, I've been busy recently with some wholly unrelated Dovecot IMAP patches, so Sieve development moved a bit into the background. This release therefore consists mostly of small bugfixes. The most important change is the fix of a bug in ManageSieve's CHECKSCRIPT command that causes a segfault. Quite a few people have encountered this problem recently, so it is about time I release this now. Changelog v0.3.2: + sieve-refilter tool: improved man page documentation by explicitly specifying the syntax used for mailbox arguments. + Sieve: spamtest and virustest extensions: improved trace debugging of score calculation. + Sieve: made error messages about exceeding the maximum number of actions more verbose. - Sieve tools: fixed problems with running as root: sievec and sieve-dump now ignore mail_uid and mail_gid settings when run as root. - Sieve: fixed bug in action accounting (for limit checking): increase action instance count only when an action is actually created. - Sieve: include extension: fixed namespace separation of :global and :personal scripts. - ManageSieve: fixed segfault bug triggered by CHECKSCRIPT command. - Fixed linking with ld.gold. - Fixed several Clang compile warnings and a few potential bugs. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.2.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] trash plugin together with sieve_before ?
by Jan-Frode Myklebust 18 Sep '12

18 Sep '12

We have a sieve script doing sieve_before to sort spam to spam-folders. Now I'm trying to configure the "Trash" plugin, but it doesn't seem to work.. I noticed my config file says: # Space separated list of plugins to load (none known to be useful so far). Do NOT # try to load IMAP plugins here. #mail_plugins = and that doveconf doesn't list any plugins loaded for "protocol sieve". Should we load quota and trash here ? -jf

[Dovecot] Shared Mailboxes in a multi domain environment
by Alessio Cecchi 18 Sep '12

18 Sep '12

Hi, I would like to enable mailbox sharing for my users. I'm using dovecot 2.1.9 with vpopmail authentication. For security reason shared mailboxes should be available only for users of the same domain. Dovecot's wiki suggest to enable acl like this: plugin { # assumes mailboxes are in /var/mail/%d/%n: acl_shared_dict = file:/var/mail/%d/shared-mailboxes.db } but in vpopmail, and also in many others configuration, mailboxes are, for example, in /var/mail/nas1/%d, /var/mail/nas2/%d and so on, so it's difficult to restrict shared mailboxes available only for the same domain. A trick could be set acl_shared_dict to /var/mail/%d-shared-mailboxes.db, but I don't know if it's safe on an NFS environment. So, why don't provide a way to restrict shared mailboxes also for dict in SQL? One way could be to add to "user_shares" table a column "domains" which is the same domain of the mailbox'owner and a config option, for acl, like acl_only_for_same_domain =yes/no so dovecot can add a "WHERE %n = domain" for the SELECT. Are there other possible solutions?

[Dovecot] dovecot 1.x: problem with quota
by Toni Mueller 17 Sep '12

17 Sep '12

Hi, I have now verified that there is a problem with quota (and sieve?). Summary: If the "maildirsize" file gets garbled (= every once in a while), mail is getting lost randomly. Details: I have a Debian box (6.0.5/amd64) with a Postfix server (2.7.1), which delivers email via Dovecot (1.2.15) to local disk (ext3). My email is filtered via a sieve script (wish I could have something better, eg. procmail). The account data is fetched from an SQL database, and I have a default quota set in dovecot.conf (200MB). My own mailbox has no quota (*:storage=0, mentioned in the database). A client sent an email to me, which is logged as being delivered like normal to my mailbox, but doesn't show up there. After poking around, I decided to simply delete the maildirsize file and have the client send that email again, and voila, it shows up in my mailbox. At the same time, however, other emails get delivered just fine, so the heinous thing is that you don't immediately notice that something fishy is going on - only when the client actually calls you (sort of defeats some uses of email)... The problem is worsened by the fact that you can't tell *which* emails get lost - you only end up with a random subset of "your" messages. The problem occurred now after running for a few months. FWIW, the problem with the garbled maildirsize file resulted in a different user's email getting bounced due to "mailbox full", when it wasn't. Questions: * Is this a known problem (Google was unhelpful/unwieldy)? * How can I prevent the problem, short of setting up a cron job to delete that file every week? * How can I log the delivery of messages in dovecot's log, not only the POP3/IMAP activity when people fetch their email? TIA! Kind regards, --Toni++

[Dovecot] clucene build warnings?
by Charles Marcus 17 Sep '12

17 Sep '12

Hi all/Timo, Is clucene still the best/recommended method for enabling full text search? Although I haven't enabled FTS yet, I plan on doing sometime in the future, and was going to be using clucene, but before I do, I'd like to see if I need to worry about an issue I've been seeing ever since I first installed clucene (and still get every time it is upgraded)... I run gentoo linux on an amd64 server, and have always gotten this warning whenever it is updated (and also got it when I first installed it): QA Notice: Package triggers severe warnings which indicate that it may exhibit random runtime failures. /var/tmp/portage/dev-cpp/clucene-2.3.3.4-r4/work/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:129:33: warning: passing NULL to non-pointer argument 2 of ‘void* memset(void*, int, size_t)’ Please do not file a Gentoo bug and instead report the above QA issues directly to the upstream developers of this software. Homepage:http://clucene.sourceforge.net/ Has anyone else ever seen similar warnings when building clucene? Is the gentoo ebuild output correct that this is not a gentoo bug, but is in fact a problem with upstream? If so, is it harmless? Or should I try to get upstream to fix it? That said, being that ianap, I probably wouldn't be much help to them, so, Timo, any chance you can see if this is a problem that needs to be addressed with them? Thanks, -- Best regards, Charles

[Dovecot] Mailbox directory permissions (LDA, 0600 -> 0660, virtual users)
by Marcin Hłybin 17 Sep '12

17 Sep '12

Hello, I have a quite common dovecot configuration with virtual users support: 1. User configuration is stored in MySQL database. 2. Mailboxes are owned by vmail:vmail with permission 0600 or drwx------. Is it possible to change mailbox mode to 0660? Dovecot version is 2.1.7 Part of SQL configuration: user_query = \ SELECT \ CONCAT_WS('/', home, u.uid, d.domain_name, u.user_name) AS home, \ 500 AS uid, \ 500 AS gid \ FROM users u \ LEFT JOIN domains d ON u.domain_id = d.id \ WHERE \ u.user_name = '%n' AND \ d.domain_name = '%d' AND \ u.active = 1 Regards. -- M.

Hi, the Drafts special folder is called "Entwürfe" in German locale. How should the special_use entry in the config file look like? Would you recommended to use the encoded folder name... mailbox "Entw&APw-rfe" { special_use = \Drafts } ...or rather the utf-8 Encoding in the dovecot config file? mailbox "Entwürfe" { special_use = \Drafts } Regards Daniel -- https://plus.google.com/103021802792276734820
