[Dovecot] (2.1 recent:) fts_decoder
by Lutz Preßler 23 Sep '11

23 Sep '11

Hello again, test setup as in previous messages. With fts = lucene, I enabled the adapted decode2text.sh (at least I tried...) as suggested in the comment section. On dovecot-start /var/run/dovecot/decode2text socket is created with sufficiant permissions (rw for anybody), but decode2text.sh is not started (it's rx for anybody). When creating lucene indexes, I cannot see it executed either (and no attachment-only content is findable afterwards). No errors with mail_debug - if I change fts_decoder to a nonexistant value, that's logged. Lutz

It is a great tool. Unfortunately dovecot allows infinate incorrect logins during a single session. When fail2ban has firewalled the ip its pointless as the rule only affects new sessions, not established ones. I am disappointed that the author of dovecot has no interest in adding a feature that closes the session after x auth failures. It would certainly make tools like fail2ban more effective. ----- Reply message ----- From: "John Alexander" <john.alexander(a)preachain.org> Date: Fri, Sep 23, 2011 00:13 Subject: [Dovecot] 64.31.19.48 attempt to break into my computer To: <dovecot(a)dovecot.org> Fail2Ban is an excellent tool to deal with this sort of thing.

[Dovecot] Dovecot 1.x vs 2.x
by Lee Standen 22 Sep '11

22 Sep '11

Hi All, I'm currently in the planning stages for a technology refresh for a very large mail installation, and looking at using Dovecot with LDA/Sieve/FTS_Solr and a number of other plugins to give our users some great features. Currently, our standard distribution is Ubuntu Lucid, which has Dovecot 1.x included with it in pre-built packages, and Dovecot 2.x is in the upcoming Oneiric beta coming out next month. My question is, are there any compelling reasons why we should gravitate towards running Dovecot 2.x beyond the fact it's the "latest and greatest" version? What features would we miss that we're likely to want or need on a very large installation (i'm talking dozens of VM's, over 1 million mailboxes). Thanks

[Dovecot] Dovecot 1.2, problem with SQL quota and mail aliases
by Jacek Osiecki 22 Sep '11

22 Sep '11

Hello, I have a small server running dovecot 1.2 (still not balsy enough to switch to 2.0 - virtual sql accounts, managesieve etc.). There are no local users - only ones defined in the SQL database, and everything else (including quota) is defined in SQL db too. Dovecot is used as IMAP daemon, and dovecot-lda is responsible for delivery (in order to make use of sieve and managesieve). I know that my configuration might be a bit ancient, but this is not referring to any bug (at least I think so) and rather to errors I've made in configuration. Several users have reported, that they are running out of quota even though their mailboxes are empty. I thought these were some single cases, but recently I discovered that this situation occurs when: - user john(a)domain.com has a mail alias, eg. john.smith(a)domain.com - he logs in to the imap account (using MUA or webmail) using his alias (john.smith(a)domain.com) In effect, all incoming emails for john(a)domain.com are increasing the counters (both "bytes" and "messages"), but since user logs in using john.smith(a)domain.com - anything he deletes from the mailbox decreases the records for john.smith(a)domain.com. Finally, John has two records: +---------------------------+-----------+----------+ | username | bytes | messages | +---------------------------+-----------+----------+ | john.smith(a)domain.com | -5488133 | -13 | | john(a)domain.com | 341411029 | 1111 | +---------------------------+-----------+----------+ The record for john(a)domain.com finaly reaches the quota limit - and even removing all emails does not help. My /etc/dovecot/dovecot-dict-quota.conf looks like this: map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } And my question is: what is used as "username"? Always the username given wher user logs in? Is there a way to provide some dictionary to translate all aliases to the real username?

[Dovecot] Trouble getting lda to gzip incomming mails (zlib plugin)
by Helge Milde 22 Sep '11

22 Sep '11

Hi! I've followed the guide at http://wiki2.dovecot.org/Plugins/Zlib to try to make Dovecot gzip incomming mails, but it doesn't seem to work. I've made pop/imap read gzipped files, and this seems to work perfectly, but LDA is still saving incomming mails in plain text. There's not too much information out there regarding the zlib module, so I'm not sure where to start debugging the problem, and was hoping someone could point me in the right direction. The only mention of zlib when LDA is delivering a file: Sep 20 15:51:19 mail dovecot: deliver(helgemil): Module loaded: /usr/lib/dovecot/modules/lda/lib20_zlib_plugin.so The most relevant lines from dovecot.conf: mail_debug = yes protocols = imap pop3 imaps pop3s mail_location = maildir:~/Maildir mail_privileged_group = mail max_mail_processes = 1024 mail_process_size = 512 protocol imap { mail_max_userip_connections = 50 mail_plugins = fts fts_squat zlib } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_max_userip_connections = 50 mail_plugins = zlib } protocol lda { postmaster_address = postmaster(a)monsternett.no mail_plugins = sieve zlib mail_plugin_dir = /usr/lib/dovecot/modules/lda sieve_global_dir = /etc/dovecot/sieve/ sieve_global_path = /etc/dovecot/sieve/default.sieve } plugin { zlib_save_level = 6 zlib_save = gz fts = squat sieve = ~/dovecot.sieve sieve_dir = ~/ } -- Helge Milde, 69701808 www.monsternett.no

[Dovecot] Create userdir on dovecot login
by Andreas Cieslak 22 Sep '11

22 Sep '11

Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine.

[Dovecot] Webmail architecture : questions about cache and storage backend
by forumer＠smartmobili.com 22 Sep '11

22 Sep '11

Hi, I have some questions about dovecot-2.1 and need some advice about software architecture. My company plans to develop a kind of Document Managing System (DMS) and one of its module is a webmail that is currently in a pre-alpha stage (if you are curious you can have a look here http://kairos.smartmobili.com/ but don't be surprised if it doesn't work and please do not use IE for now). From my personal analysis that I am sure is incomplete we have the following options to handle emails storage and cache: 1) Do not use a cache and rely on dovecot performance to retrieve email's header in real time. Actually don't know if it's that simple because we might need to have a transformed version of emails to be able to display them more easily in the webmail. In this case this option is not really possible. 2) Use new dovecot-2.1 imap backend and develop a kind of dummy imap server listening to a custom port and storing emails inside a mongoDB database. Advantage is it allow replication very easily. 3) Wait for dovecot2.x to implement a NoSQL storage. Will it happen soon ? If you have other suggestions or ideas I would be happy to hear them.

[Dovecot] Sieve: Vacation, handle and variable
by René Neumann 21 Sep '11

21 Sep '11

Hi *, I am adding a generic way for vacation-replies in my sieve setup. There I set the handle and the reason using variables (see end of mail). My simple question now is: Though variable expansion is not done for subject and reason, is it done for the handle? Because else there seems no way in configuring the vacation action via variables. I tried to read the code for this extension, but ... well ... the whole sieve implementation is way more complicated then I figured ^^. Thus I take the question to the list. Thanks, René ----- default.sieve ----- require [..., "include", "variables"]; # set this to the text you want to get included in the vacation-mail global ["vacation", "vhandle"]; set "vhandle" ""; set "vacation" ""; [...] include :personal "vacation"; ----- vacation.sieve ----- require ["variables", "include", "vacation"]; # this is set in the including script global ["vacation", "vhandle"]; if string :is "${vacation}" "" { return; } # ensure we have a handle if string :is "${vhandle}" "" { set "vhandle" "${vacation}"; } if header :matches "subject" "*" { set "sbj" "Out of office [was: ${1}]"; vacation :addresses [...] :from "..." :days 7 :handle "${vhandle}" :subject "${sbj}" "${vacation}"; } -------------------------

[Dovecot] About using Dovecot indexes with Thunderbird/kmail
by Anton Aylward 21 Sep '11

21 Sep '11

I have Dovecot running well on my Mandriva mail hub, handing out IMAP to the household LAN. This is 1.2.15. Eventually I'll upgrade the OS and get 2.x, but this is working fine. So this question is really about the mail readers I use and how they make use of Dovecot. I have Thunderbird on my laptop and KMail2 on my desktop. Dovecot indexes. GOOD! The trouble is that the mail readers want their own indexes :-( I wish that Thunderbird would NOT index mail on my laptop, but it does. I wish Kmail2 would not use nepomuk/akonadi to index the mail but it does. Why can't they both believe the indexes used by Dovecot? Is this an unreasonable request? -- "We stand behind all of our products, except for the manure spreader." -- Corporate motto of an equipment manufacturer

[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).

[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

I'm still calling it "alpha" in case I think of doing some more API changes, but I think the next one will be called "beta1", hopefully soon followed by "rc1". - Statistics gathering improvements (more fields) and fixes. - Lots of imapc fixes and improvements - Fixes to handling shared namespaces - Several other fixes

[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] Warning: Subscriptions file .. Removing invalid entry:
by Jan-Frode Myklebust 15 Sep '11

One of our dovecot-servers (v2.0.14) got a bit too busy last evening: Sep 13 20:39:18 popimap1 dovecot: master: Warning: service(pop3-login): process_limit reached, client connections are being dropped then logged a few: Sep 13 20:39:20 popimap1 dovecot: pop3(XXXXXXXXX(a)YYYYY.YY): Warning: I/O leak: 0x3829233d20 (10) Sep 13 20:39:20 popimap1 dovecot: pop3(XXXXXXXXX(a)YYYYY.YY): Warning: Timeout leak: 0x3829233ce0 Sep 13 20:39:20 popimap1 dovecot: pop3(ZZZZZ.ZZZZZ(a)ZZZZZZ.ZZ): Warning: I/O leak: 0x3829233d20 (10) Sep 13 20:39:20 popimap1 dovecot: pop3(ZZZZZ.ZZZZZ(a)ZZZZZZ.ZZ): Warning: Timeout leak: 0x3829233ce0 Sep 13 20:39:20 popimap1 dovecot: pop3(YYYYYYY(a)YYYY.YYY): Warning: I/O leak: 0x3829233d20 (10) Sep 13 20:39:20 popimap1 dovecot: pop3(YYYYYYY(a)YYYY.YYY): Warning: Timeout leak: 0x3829233ce0 Sep 13 20:39:20 popimap1 dovecot: pop3-postlogin: Error: Fatal: fd_send() failed: Broken pipe Sep 13 20:39:20 popimap1 dovecot: pop3-postlogin: Error: Fatal: fd_send() failed: Broken pipe and: Error: net_connect_unix(/var/run/dovecot/pop3-postlogin) failed: Resource temporarily unavailable but what has me a bit worried is these: imap(user(a)xxx.xxx): Warning: Subscriptions file /path/to/user(a)xxx.xxx/subscriptions: Removing invalid entry: .Sent imap(user(a)xxx.xxx): Warning: Subscriptions file /path/to/user(a)xxx.xxx/subscriptions: Removing invalid entry: .Spam imap(user(a)xxx.xxx): Warning: Subscriptions file /path/to/user(a)xxx.xxx/subscriptions: Removing invalid entry: .Drafts imap(user(a)xxx.xxx): Warning: Subscriptions file /path/to/user(a)xxx.xxx/subscriptions: Removing invalid entry: .Trash which happened for a two users during this high load periode.

[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. Although caching can help. e.g., Here's what the first connection to the server looks like (this is using IMP 5 on a mailstore with 82 messages): S (1315951197.4976): +OK Dovecot ready. C (1315951197.513): [AUTH PLAIN Command - username: slusarz] S (1315951197.5319): +OK Logged in. C (1315951197.5325): STAT S (1315951197.5328): +OK 82 482351 C (1315951197.5348): UIDL S (1315951197.5354): +OK S (1315951197.5354): 1 000000014935d409 S (1315951197.5354): 2 000000024935d409 S (1315951197.5354): 3 000000114935d409 [...] S (1315951197.5363): 82 000000824935d409 S (1315951197.5363): . C (1315951197.9582): TOP 1 0 S (1315951198.0411): From user(a)domain.com Thu Jun 22 11:16:26 2006 [...] S (1315951198.0416): . [...] C (1315951199.0607): LIST S (1315951199.061): +OK 82 messages: S (1315951199.061): 1 118630 [...] S (1315951199.0619): . 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.
