by Lutz Preßler 20 Sep '11

Hello! I have problems recompiling the Debian squeeze auto build packages with "--with-lecene". Is the git (2.3) version of CLucene necessary? Debian includes 0.9.21b, which does not work. Lutz

[Dovecot] Default permissions on newly created maildir
by Alex 20 Sep '11

20 Sep '11

Hi Guys, I am setting up SQL auth for mail. Auth works fine, I notice that if no maildir exists for the authenticated user, it is created automatically (depending on the homedir specified in the sql table entry). The problem is that it creates the dir with "700" permissions which is causing grief for my MTA when it comes time for it to try and drop mail there. If I chmod the dir to 770 things work fine. How do I change the default permissions that dovecot uses whenever it creates a new mail account?

[Dovecot] Deleted mailboxes with lazy_expunge
by Angel L. Mateo 19 Sep '11

19 Sep '11

Hello, I'm trying to configure lazy_expunge plugin (as a way to provide easy backup for mails). This is my configuration (as explained in dovecot wiki): # Default namespace namespace { prefix = separator = / inbox = yes } # namespaces for lazy_expunge plugin: namespace { prefix = .EXPUNGED/ separator = / location = maildir:~/Maildir/expunged } namespace { prefix = .DELETED/ separator = / location = maildir:~/Maildir/deleted } namespace { prefix = .DELETED/.EXPUNGED/ separator = / location = maildir:~/Maildir/deleted/expunged lazy_expunge = .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/ I use just one namespace because I don't want to differentiate between deleting mails or deleting mailboxes, but I have the same problem using the 3 namespaces. With this configuration, when a user connects, if he doesn't have the expunged folder, dovecot logs: Sep 16 10:53:35 myotis30 dovecot: imap(angel.luis): Debug: Namespace : type=private, prefix=.EXPUNGED/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir/expunged Sep 16 10:53:35 myotis30 dovecot: imap(angel.luis): Debug: maildir++: root=/home/alumnos/46/113246/Maildir/expunged, index=, control=, inbox= Sep 16 10:53:35 myotis30 dovecot: imap(angel.luis): Debug: Namespace .EXPUNGED/: Permission lookup failed from /home/alumnos/46/113246/Maildir/expunged Sep 16 10:53:35 myotis30 dovecot: imap(angel.luis): Debug: Namespace .EXPUNGED/: Using permissions from /home/alumnos/46/113246/Maildir/expunged: mode=0700 gid=-1 and the expunged folder is created (without the cur, new neither tmp folders).

But when I try to delete a whole imap folder (in the example I delete it from trash folder because I use thunderbird and it previously move the folder to trash), dovecot logs: Sep 16 11:45:46 myotis30 dovecot: imap(angel.luis): Debug: Namespace .DELETED/: Using permissions from /home/alumnos/46/113246/Maildir/deleted: mode=0700 gid=-1 Sep 16 11:45:46 myotis30 dovecot: imap(angel.luis): Debug: Namespace .DELETED/: Permission lookup failed from /home/alumnos/46/113246/Maildir/deleted/.Trash.kk-20110916-114546 Sep 16 11:45:46 myotis30 dovecot: imap(angel.luis): Debug: Namespace .DELETED/: Using permissions from /home/alumnos/46/113246/Maildir/deleted: mode=0700 gid=-1 Sep 16 11:45:46 myotis30 dovecot: imap(angel.luis): Debug: Namespace .DELETED/: Permission lookup failed from /home/alumnos/46/113246/Maildir/deleted/.Trash.kk-20110916-114546 Sep 16 11:45:46 myotis30 dovecot: imap(angel.luis): Debug: Namespace .DELETED/: Using permissions from /home/alumnos/46/113246/Maildir/deleted: mode=0700 gid=-1 and my mail client reports the error "[CANNOT] Can't rename mailboxes accross specified storages" and the mail folder isn't created in the DELETED namespace.

[Dovecot] default_pass_scheme = PLAIN and blank password
by Gary V 18 Sep '11

18 Sep '11

I'm using Dovecot 1.2.15 on Ubuntu, but I think this applies to other versions as well. I store user info and passwords in MySQL. It appears 'default_pass_scheme = PLAIN' allows blank passwords. My question is: Is this a bug or is this by design? If it is by design, is there a setting that I'm not aware of that changes this behavior? Of course let me know if you need additional info on the setup I'm using. Thank you, Gary V

[Dovecot] Auth protocol and XMPP
by Kim Alvefur 17 Sep '11

17 Sep '11

Hello. I've written an authentication backend for the XMPP server Prosody, which makes it use Dovecots auth socket and protocol, and letting the client use any SASL mechanism Dovecot offers. However, setups using the full user@domain as authnid won't work, due to most XMPP clients assuming that the authnid is the localpart. I want to avoid hardcoding it to PLAIN, or otherwise doing MITM/rewrites if possible. (There exists an older auth backend that does just that already) Ideas? -- Kim Alvefur <zash(a)zash.se>

[Dovecot] Detecting duplicate messages with sieve
by Aleksandar Lazic 17 Sep '11

17 Sep '11

Dear Listmember, I use http://www.courier-mta.org/reformail.html for "Detecting duplicate messages" ### The -D option implements a simple way to delete duplicate messages in incoming mail. filename is a file that will be approximately 'len' bytes long. This file will be used by reformail to save message IDs seen in recent mail. reformail reads the message on standard input. If the message has a Message-ID: header that's already in the cache file, reformail terminates with the exit code set to 0. Otherwise, reformail terminates with the exit code set to 1. ### ### my entry in mailfilter `reformail -D 8192 $HOME/.msg.cache` if ($RETURNCODE == 0) { /^From: *!.*/ FROM1=${MATCH2} /^Subject: *!.*/ log "$FROM (${FROM1}) => Not Delivered duplicate MSG-ID. Subject ${MATCH2}\n" exit } ### Is there a similar feature in sieve or can I still use the upper setup? Another question is about to add this header line in every mail. xfilter "${REFORMAIL} -a\"Lines: $LINES\"" Thanks for your help. BR Aleks

Ok, I thought I tested accessing the mailbox afterwards, too - but I probably had not. I have a more general problem now: shared mailboxes from any "non-INBOX" namespace are not available to other users. That's not only with virtual or imapc namespaces, but also tested with two Maildir ones: namespace personal { inbox = yes location = maildir:~/Maildir prefix = INBOX. type = private } namespace second { inbox = no location = maildir:~/Maildir2 prefix = INBOX.second. type = private } namespace others { type = shared separator = . prefix = INBOX.shared.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u #location = maildir:/home/%%n/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } [...] I can as user1 SETACL INBOX.second.box ~user1/Maildir2/dovecot-acl-list contains "1316082286 box" ~user1/Maildir2/.box/dovecot-acl contains "user=testuser lrs" (as does ~user1/Maildir/.in2007/dovecot-acl) The shared mailboxes dict contains shared/shared-boxes/user/testuser/user1 1 But - as testuser - 0 list "" "*" * LIST (\HasChildren) "."

[Dovecot] Shared folder not listing
by Tom Clark 16 Sep '11

16 Sep '11

Hi Timo, I've got a weird problem on our dovecot. We're trying to setup private shared folder access. I have 2 users. tom(a)mailbox.com and system(a)mailbox.com. I have set the ACL's on all the folders (and subfolders) on system(a)mailbox.com. However, I'm not getting any of them listed when I check tom(a)mailbox.com <mailto:tom@mailbox.com's> 's IMAP folders. Our configuration is below (we're migrating from Courier hence the INBOX.): In 10-mail.conf: namespace { type = private prefix = INBOX. separator = . inbox = yes list = yes hidden = yes } namespace { type = shared separator = . prefix = INBOX.Shared.%%u location = maildir:%%h/Maildir:INDEX=~/Maildir/Shared/%%u subscriptions = no list = children } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins imap_acl } In 90-acl.conf: plugin { #acl = vfile:/etc/dovecot/acls:cache_secs=300 acl = vfile } # To let users LIST mailboxes shared by other users, Dovecot needs a # shared mailbox dictionary. For example: plugin { acl_shared_dict = file:/var/vpopmail/domains/%d/shared-mailboxes } Have I missed anthing!?!? Thanks in advance! Tom

[Dovecot] Maildir "locking"
by Attila Nagy 15 Sep '11

15 Sep '11

Hello, I'm looking for the alternative of qmail's chmod -t (sticky bit on the maildir root) for Dovecot. What I'm trying to achieve with this lock: - Dovecot lmtp should give back a temporary error (so the email will be deferred and re-delivered later) - all other Dovecot daemons (pop, imap) should work as usual, but should not alter maildir contents (they can modify their own files, like indexes, logs etc) What is the best way to do this? If there is no such thing currently, would it be hard to implement the sticky bit checking on the root? Thanks,

[Dovecot] Which dovecot-antispam with dovecot 2?
by Svoop 14 Sep '11

14 Sep '11

Hi I'm a little confused as there are two repos for the dovecot-antispam plugin. Eugene's hg repo is explicitly labeled "for Dovecot 2", but the Johannes' git repo has commits later in date: hg: http://wiki2.dovecot.org/Plugins/Antispam git: http://git.sipsolutions.net/?p=dovecot-antispam.git I guess the unrelease hg code ist the one for Dovecot 2, but what is Eugene's 1.4 code for? Thanks!

[Dovecot] Shredding instead of deleting
by Mike Cardwell 14 Sep '11

14 Sep '11

Hi, I have a wishlist item. Is there an appropriate place for me to post it? Basically, I would like to know that my email isn't recoverable from the local disk on the mail server after I delete it. So instead of just deleting the file from my Maildir, I'd like the option to exist for Dovecot to shred it.. Ie, overwrite the file with random data and/or null bytes before deletion. In the same way that GNU shred behaves: https://www.gnu.org/software/coreutils/manual/html_node/shred-invocation.ht… -- Mike Cardwell https://grepular.com/ https://twitter.com/mickeyc Professional http://cardwellit.com/ http://linkedin.com/in/mikecardwell PGP.mit.edu 0018461F/35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F

You mean downloading the entire data of the messages from the POP3 server? This is expected behavior when using a stateless (e.g. webmail) client. Kind of the whole reason you don't use POP3 in the first place.

We need to grab all headers so we can build the envelope information (needed to produce the mailbox listing). And the LIST command grabs the size information (also used in the mailbox listing). But remember that the full headers will need to be redownloaded *EVERY* time you reload the page unless some sort of caching is enabled in the client. That's just the nature of POP3. (IMAP has the same sort of issues - if the stateless client does not cache, the envelope information must be downloaded on every access. However, with IMAP, the network traffic is reduced - you can download only the needed information, not all header text - and IMAP servers have the ability to cache this information behind the scenes due to the abstraction of the API.). This is where caching is pretty much essential on the webmail side. If caching is enabled, the best-case scenario is that the the webmail server only needs to grab the list of UIDLs on every POP3 server access going forward - if the UIDL list has not changed, we know the mailbox hasn't changed and the cached information is still valid. (CONDSTORE/QRESYNC extensions for IMAP make this synchronization check even more efficient in IMAP) michael

[Dovecot] General IMAP Question
by Gerald LaMontagne 14 Sep '11

14 Sep '11

Hi- I'm developing an IMAP client library in lua and tried using a literal form of the STATUS command. Dovecot rejected the command. I was successfully able to use a literal form of the LOGIN command, so I have some confidence in my code working properly. Is this correct and, if so, is there a list of IMAP commands that don't support the literal form? I searched hi and lo for something, but have been unable to find an answer. Thanks for your time. Regards- Gerry LaMontagne

[Dovecot] New plugin for Pigeonhole Sieve: sieve_pipe
by Stephan Bosch 14 Sep '11

14 Sep '11

Hello, I've finished up work on a new plugin for Pigeonhole Sieve: sieve_pipe. It adds a new Sieve extension (vnd.dovecot.pipe) providing a new action command that provides the possibility to pipe messages to external programs (e.g. shell scripts). The programs available to this command are explicitly limited and subject to administrator configuration. The plugin can currently only be downloaded from the Mercurial repository: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe Check the README/INSTALL files in the repository or the new wiki page for more information: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/README http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/INSTALL http://master.wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe The specification of the vnd.dovecot.pipe extension can be found here: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/doc/rfc/spec-… I'd still call this thing very much experimental, so be sure to test it extensively first. Don't hesitate to notify me when there are any problems. Regards, Stephan.

[Dovecot] quota percents
by Micah Anderson 13 Sep '11

13 Sep '11

I've noticed that http://wiki2.dovecot.org/Quota/Configuration is out of date, it says: plugin { quota = maildir:User quota quota_rule = *:storage=1GB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=10%% # 20% of 1GB = 200MB quota_rule3 = Spam:storage=20%% } but if you use the '10%%' notation, dovecot complains, and *also* incorrectly: dovecot: imap(test(a)example.net): Warning: quota root mail quota rule Trash:bytes=10%: obsolete configuration for rule 'bytes=10%' should be changed to 'bytes=+10%' its incorrect because if you change it to what it suggests ('+10%') it wont work because that wont be 10% more, rather, it is set to bytes=+10: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+10 messages=0 clearly, that isn't right... so I guess it needs to be changed to '+10%%', setting that provides: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=* bytes=2211724 messages=0 dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+221172 (10%) messages=0 that seems ok, its saying the Trash mailbox is set to have 221172bytes (215 kilobytes) of quota. So, clearly http://wiki2.dovecot.org/Quota/Configuration needs to be updated. However, it doesn't seem to work in practice, because I have a user that is at 99% of quota, with nothing in the Trash who cannot move a 77KB message into the Trash without getting the quota_exceeded message and refusing to move it. so... how do I get this to work? thanks! micah --

[Dovecot] Migrating a dovecot setup from one server to another
by James Carr 13 Sep '11

13 Sep '11

Hi All, I have a server with a dovecot + postfix setup and unfortunately the server is EOL'd. I have built a new ubuntu server out and I'm in the process of migrating everything over. In migrating the dovecot setup over, this is the list of items I have done: install dovecot, postfix, etc on the new server copy configuration files over copy /var/spool and /var/mail over Is there anything else I need to consider before switching MX records to point to the new server? Thanks, James

Hello (Timo), yes, I know... maybe it's a bit far fetched, but I do have a use case. Would it be (reasonably easily) possible to implement IMAP ACL support for "imported" imapc namespaces/mailboxes?

Hello, Right now, I'm using Exim and a customized version of an old (10 years old) Atmail POP3 server written in Perl, with ~10000 mailboxes located on a Lustre file system. So far so good. Though, I plan to migrate from Atmail to Dovecot, to provide our customers with IMAP support. Has anyone any experience with Dovecot on Lustre FS ? Thanks Christian

[Dovecot] Problem with configuring dovecot to take namespaces from database
by Marcin Mirosław 13 Sep '11

13 Sep '11

Hello! I'd like to set up dovecot to keep namespaces in database, keep more than one namespace per user. I try to create the simplest rule (even without tuple in db table) to get new namespace, unfortunately it doesn't work. My user_query is: SELECT '/dane/domeny/%d/mail/%n/' as home, dovecot_typ_skrzynki ||':'|| '/dane/domeny/%d/mail/%n/' ||'.'|| dovecot_typ_skrzynki as mail_location, '*:bytes='||quota_mb||'M' as quota_rule , 'test33/location=mdbox:~/.mdbox/test33/' as "namespace/test3/prefix" In debug log i'm getting: Debug: master out: USER#0111#011user@examle.com#011home=/dane/domeny/mejor.pl/mail/marcin/#011mail_location=maildir:/dane/domeny/mejor.pl/mail/marcin/.maildir#011quota_rule=*:bytes=0M#011namespace/test3/prefix=test33/location=mdbox:~/.mdbox/test33/ If i knew how it should look like the line in auth debug log for working configuration it could be easier for me to write correct sql query. May i please for advice?

[Dovecot] MySQL, map files
by Steve Fatula 13 Sep '11

13 Sep '11

I'll try and break up my questions the other day about extdata that went unanswered into pieces in the hopes it will be more specific and clear. In general, I am trying to figure out the syntax of the map statement and what is allowed in that statement. So, by map statement, I mean for example perhaps the dovecot-dict-expire.conf.ext file as shown in the doc. Is the syntax the same for the various types of files (quota vs expire)? Is there syntax to allow the specification of a different key? If so, where is this documented. I have an existing table I want to use, not the table shown in the doc. The reason I am asking is I have seen web pages that reference all sorts of statements within the map statement, and I have no idea where they are documented. Specifically, I see an example here (which is LDAP), look in section 3: http://dovecot.org/patches/1.2/ldap/HOWTO_dictldap+extdata.txt You will see lots of statements, not sure which ones can be used for MySQL (instead of LDAP). So, would like to find a list of ALL valid syntax within the map.

[Dovecot] director ignoring director_mail_servers for lmtp connections

Hello, Following Jan-Frode's advise I am trying this configuration: {postfix} ---lmtp---> {director} ---lmtp---> {dovecot} so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively. whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

[Dovecot] signal 11 crash, sometimes, during mbox bz2 decompression
by Mike Brown 13 Sep '11

13 Sep '11

Hello again, I'm running dovecot 1.2.16 from the ports collection on FreeBSD 8.1-STABLE, amd64. To enable IMAP read-only access to gzip or bzip2 compressed mbox files, I added the following to my dovecot.conf, in the protocol imap { ... } section: mail_plugins = zlib My compressed mbox files are all .bz2 files in an 'old' subdirectory of my main mail directory. I am trying to access them with Thunderbird. I 'subscribed' to them just fine, and at first I thought it was working, but I just got lucky on the first couple I accessed. Dovecot actually fails to decompress them about 90% of the time, seemingly at random; the same box will not work a bunch of times, then work once, then not work again and again. When it works, sometimes only some of the messages get transmitted. Most of the failures are accompanied by this pair of messages in my log: Aug 16 00:25:33 myhost dovecot: dovecot: child 943 (imap) killed with signal 11 (core not dumped - set mail_drop_priv_before_exec=yes) Aug 16 00:25:33 myhost kernel: pid 943 (imap), uid 1001: exited on signal 11 Some of the failures have only the "exited on signal 11" message. The very first failure had this: Aug 16 00:22:47 myhost dovecot: IMAP(mike): Next message unexpectedly lost from mbox file (read-only mbox stream) at 2761 (cached) Aug 16 00:22:47 myhost dovecot: IMAP(mike): read(mail, uid=2) failed: Invalid argument Is this a problem with dovecot? Let me know if/how I can help, or what other info you need. Thanks, Mike

[Dovecot] Custom error messages.
by Lauro C. 12 Sep '11

12 Sep '11

I am using Dovecot 1.2.9. Is it possible to have custom error messages? I want to translate some of the messages (for instance mailbox full), so it can be more user friendly. I already use the quota warning feature. But I need to translate the messages anyways, is it possible? Lauro

[Dovecot] Possible to Customize File Naming Scheme?
by Dave Stubbs 12 Sep '11

12 Sep '11

Hello all, [Sorry if this has been covered already - I searched back a little way in the archive and didn't find anything recent on the topic.] I'm wondering if it is possible to customize the way dovecot creates or modifies filenames in the maildir directories? I'm watching how my mail system works, and I see that procmail creates a new file in the <folder>/new directory, each time an email is received. This file is some complex combination of UIDs and things, suffixed by the server name. So far, the filename has alphanumerics, a couple underscores, and a dot or two only. But once dovecot gets it's hands on the file and moves it to the <folder>/cur directory, it starts doing "terrible" things to the file name. Now, the filename starts to have "evil" things in it, like colons and commas. Is there a way to change this? I'm asking this primarily because I use dovecot as a massive long-term email archiving system. One of the things one needs to be able to do when running a long-term archive like this is keep things as simple and accessible as possible. The reason I use maildir is that I totally buy into the "one email, one file" idea - it means I don't have to store messages in big consolidated database files that are changeable with each new version of the vendor's software release (such as exchange DBs or Outlook PST files) or that are horrible performers (such as mbox). One of the nice things about the maildir "each email is a separate file" idea is that you are not limited to maildir or dovecot or any other piece of software to handle, read, and process the files. For instance, I would like to backup my maildir by using rsync to synchronize my dovecot-managed maildir to a Windows server running NFS. From there the files are synchronized via Windows DFS ( to which there is no open source solution that is even close) to several other servers around the continent. Only thing: The evil commas and colons in the filenames are anathema to Windows. So instead I tar the maildir folders to tgz files on the windows server, and the tgz's are synchronized to other DR sites. If I could do without the need for tar (mandated solely because of the colons and commas in the dovecot filename scheme) I could minimize the time to backup (only synchronizing changes) and suddenly I would have a lot of other benefits opened up. One simple one would be that if I could configure dovecot to append the .eml extension to the end of every file (technically each file in a maildir is an eml file regardless of the extension being present or not - eml is just a raw mail file just like what you'd find in a maildir) I would have instant access to them using Search Server Express, which can read eml files but strongly prefers to use extentions to recognize files as such. To be clear: I'm not requesting that dovecot's file naming convention be changed to match my quirky requirements - I'm just asking if it could be made configurable, so I could change it to match my needs and others could change it to match theirs. In the interests of REALLY being able to use the elegantly simple idea of each mail being a separate file, I'm trying to get more out of that great pile of folders and files I'm amassing in my mail archive server. The more use I can make of them with other software other than dovecot (i.e. data crawling, indexing, easy recovery in a catastrophe, etc) the more valuable this format is. Is this possible?
