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. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common-session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[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 17 Sep '11

17 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.

[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

[Dovecot] imapc and imap_acl
by Lutz Preßler 13 Sep '11

13 Sep '11

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? There is no local directory (like with the virtual plugin) yet...

[Dovecot] Dovecot and Lustre FS
by Christian Gregoire 13 Sep '11

13 Sep '11

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
by mailing lists 13 Sep '11

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.

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?

[Dovecot] userdb static & Quota from LDAP?
by Christian Schmidt 12 Sep '11

12 Sep '11

Hi all, I just configured Dovecot 2.0.14 for "virtual" (i.e. non-system-) users: passdb { driver = ldap args = /etc/dovecot/conf.d/ldap-passdb.ext } userdb { driver = static args = uid=vmail gid=vmail home=/var/maildir/%u } Works fine so far - thanks for this great piece of software, Timo!!! Now I'd like to add per-user quotas that will also be stored in the LDAP directory, and I'm not sure how to put things together. IMHO quota is the only "userdb information" requested from LDAP, and I'd like to leave all the other "userdb pieces" as the are. I changed the userdb definition to: userdb { driver = ldap args = /etc/dovecot/conf.d/ldap-userdb.ext } My /etc/dovecot/conf.d/ldap-userdb.ext contains (along other lines): user_attrs = uid=vmail,gid=vmail,home=/var/maildir/%u,mailQuota=quota=quota_rule=*:storage=%$ My quota configuration looks like this: plugin { quota = maildir:Mailbox-Quota quota_rule = *:storage=1G quota_warning = storage=80%% /usr/local/bin/quotawarn.sh 80 %u quota_warning2 = storage=95%% /usr/local/bin/quotawarn.sh 95 %u } Using this setup, "doveadm quota get -u username" doesn't reveal any quota information (except from the "headings"). Instead, dovecot logs: doveadm(username): Fatal: GID 0 isn't permitted When switching back to userdb static, I receive the correct (but also) static quota information. What am I doing wrong? Thank you very much, Christian Schmidt -- question = ( to ) ? be : ! be; -- Wm. Shakespeare

Also do you see anything in error logs? If you're using the default pop3_uidl_format it'll rely on IMAP UIDs to stay the same, and I guess it's possible that due to some other problem they change (that should be logged as an error/warning though). You could try setting pop3_uidl_format=%f, but it will cause everyone to redownload mails. With newer Dovecot versions you could set pop3_save_uidl=yes and when you think everyone's downloaded mails once you can safely change the pop3_uidl_format.

[Dovecot] Dsync and hidden files
by Dick Middleton 12 Sep '11

12 Sep '11

Hi, I'm in the process of changing from Dovecot v1 to v2 and changing to mdbox in the process. I've come across a little problem which I was hoping there would be a workaround for. There are sieve config files in the home directories which are hidden files. Dsync croaks when it finds one of these because they are not mbox format. It would be nice if they were ignored (or copied unchanged). Is there another way to deal with them other than by deleting thm? Dick

[Dovecot] general advice sought
by Alan Brown 12 Sep '11

12 Sep '11

I'd like to hear the thoughts of list members on which type of storage method seems "best" for inboxes and for folders. The filesystem is GFS2 and for various reasons I can't change it. Inboxes - currently Mbox format. Some users have upwards of 5000 messages in there (the largest is about 18k entries) and thanks to attachments some inboxes are 40-200Mb with a few sitting at 2-3Gb. (Suicidal, I know but enforcing rules is politik-laden and getting academics to behave sensibly is like herding cats) Folders: Mdir format. Thanks to GFS2 filesystem limitations(*) I'm currently enforcing a limit of 4000 messages/folder. It'd be nice to have a "better" way of storing these which doesn't drive up backup loads tremendously. The mail spool has around 6 million files in the folders, covering about 400Gb. GFS2 filesystem limitations are painful. While there are no hard limits, It really doesn't cope well with a lot of files in any given directory thanks to limitations in the way that cluster locking is propagated, There are marked slowdowns about 100 files, this becomes awful above 1000 and effectively unusable above about 8000 entries as the entire IO system gets halted momentarily when such directories are opened and the directory may take up to 5 minutes to return a "ls" result. Some users had upwards of 80k files in their mail folders (~40k messages) and accessing these brought the entire system to a halt. If I migrate to other formats (eg mdbox), then it needs to be able to be done on the fly. (Taking the mailservers down for a day won't go down well, even an hour raises howls). Any suggestions?

For the Gmail mailboxe the INBOX.gmail prefix is missing and / is used as separator.

[Dovecot] Read-only mbox files
by Tim Bishop 12 Sep '11

12 Sep '11

Hi all, I'm using Dovecot 1.2.16 (I can upgrade to 2.0 if need be) and I'm having trouble stopping Dovecot from modifying mbox files. The setup is that my main namespace points at my Maildir mail folders. In addition to this I have a second namespace that points at some old archived mbox folders. I rarely need to access these folders, but when I do Dovecot modifies the files (adding UID headers, etc). What I'd like to do is make it so that Dovecot can't change these files. I thought there might be a setting to mark a mail_location as read-only, but I can't find anything like that. I've looked at ACLs too, but they seem to be more about user access that what Dovecot can do to files. I could just do this at the filesystem level, but I'd feel a bit happier about working with Dovecot rather than trying to work around it. Does anyone have any suggestions? Thank you for reading.

[Dovecot] sieve and pattern matching
by David Newman 11 Sep '11

11 Sep '11

Dovecot 1.2.17 What is the sieve syntax for matching text somewhere in a subject line, but not at the beginning of the line? Background: Multiple machines each send a message with the subject of "<hostname> operations run" to a mail server. The <hostname> value is different for each sender. This sieve filter does not match any message: require ["fileinto","envelope","reject","vacation","imapflags","relational","co mparator-i;ascii-numeric","regex","notify"]; require ["body", "fileinto", "regex"]; # currentops reports if header :contains "Subject" ".* operations run" { fileinto "currentops"; stop; } However, a similar filter will match if, and only if, the string occurs at the beginning of the subject line. The various sieve help pages I've found suggest that pattern matching anywhere in the subject line should work, not just at the beginning. How to achieve this? TIA dn

[Dovecot] Annoying "feature" in dovecot/pidgeonhole - include depth limitation
by Mihai Moldovan 11 Sep '11

11 Sep '11

Hi all, I'm using dovecot 2.0.14 build on Debian. The maintainers obviously patch the dovecot source so that it uses the pidgeonhole sieve system. Today I ran into a very annoying issue: I created several sieve scripts and interlinked via the include command, only to find dovecot spewing this error message at me: SWREG Newsletter: line 14: error: cannot nest includes deeper than 10 levels. As far as I could see this limitation is hardcoded to a depth of 10 and can only be changed at compile time. Why is it in place? I understand that you CAN create loops via the include command and limiting the inclusion depth is a way to circumvent loops - but ten is a very low value and the fact that you can't change it via a config file or sorta is even worse. My "fix" so far has been ignoring this, i.e. not returning false. I'm pretty sure that's not the best way to do it but it seems to be working so far. I'd really like to hear your opinion on this issue. Best regards, Mihai **

[Dovecot] Sieve, before script - Can it include "personal" scripts?
by Steve Fatula 11 Sep '11

11 Sep '11

Using sieve_before, can the script it references include a file from the personal space? I want to set some parameters (by user using the variables extension) there to control what the before script does, so, every user would have the file in their personal include space. If not, is there another way? Can the sieve_before and sieve_global_path be set from userdb extra fields?

Hi list, currently I use dovecot v1.2.15 with maildir++ mailboxes. (Debian Squeeze) I want to set up a different server with dovecot v2, also maildir++ mailboxes. (also Debian Squeeze) What is the best way to copy the existing mailboxes from the older machine running dovecot v1.2.15 to the new naked machine? Greetz, Tobias

[Dovecot] debug user's message retrieval
by Костырев Александр Алекс еевич 10 Sep '11

10 Sep '11

Hi there! Is there any method to log user's activity with pop3 service? I'll try to explain situation: In maillog I saw that my dovecot lmtp saved four letters in user's mailbox. After a while I got a call from that user saying that he received nothing. Is there any method to log that that user RETR every single letter, maybe with full names of letter's id or something like that?

What webmail is this? It's Horde webmail. Webmail does pop. Yahoo and Gmail do it too. When I first set up the server, it did it on first login - obviously because the server had changed but it's doing it once a week now (and in fact, it did it twice today). It's not fatal, no one will die. It is a PITA though. Simon

[Dovecot] Mails repopping
by Simon Brereton 09 Sep '11

09 Sep '11

HI I don't know if this is a dovecot issue or a client one. But as Dovecot is the most recent change, I'll start here. I have a server that's been running Courier for about 6 years and in all that time I think I've only ever had 1 issues where an entire mail box was repopped by a webmail client. However, since moving to a new server and dovecot 4 weeks ago, I've now had the webmail client repop this account 4 times (there are about 230 mails in the account). Is there a setting I need to tighten to prevent/remedy this? I have no idea if it's happening on other accounts, but this is one that I see. The format is maildir. There has been no changes to the webmail client. Thanks. Simon

[Dovecot] copy and empty userA folder1, append to /var/mail/userB
by mathog 08 Sep '11

08 Sep '11

Dovecot 2.0.13 on a 64 bit linux. We have an archiver account on one machine. Most mailing lists that handles go directly to it and everything is fine. However, there is one campus list that will only send to real people. So for that one I subscribed. When one of these messages comes in, which is 1-2x per week, I copy it to an export folder and then manually run a script which does: cat ~me/mail/export >>/var/mail/archiver echo "" > ~me/mail/export That worked fine on our last system, but dovecot doesn't like it. It leaves the imap indices for the export mailbox in an inconsistent state, so that roundcube (through dovecot) refuses to drop messages into it. The error message roundcube emits is: ServerError: Mailbox isn't a valid mbox file. Presumably the second half is from dovecot. I need a supported way to go about this, so that the next time one comes in I can copy to that folder again. The export mailbox is always completely emptied. It would suffice if there was some way to force dovecot to create "empty"" .imap/export: dovecot.index.cache dovecot.index.log files. Note this isn't a problem for the archiver itself, since it doesn't have any imap indexed files. Suggestions? Thank you, David Mathog mathog(a)caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech

[Dovecot] limit number of simultaneous lmtp deliveries ?
by Jan-Frode Myklebust 08 Sep '11

08 Sep '11

We have quite a few frontend mail gateways that deliver incoming email trough our dovecot director (lmtp proxy) to the backend lmtp servers, and are seeing this logged on the frontend mail gateways: Sep 5 10:51:56 mailgw1 postfix/lmtp[23443]: 0E2F41C01A: to=<me(a)example.com>, relay=loadbalancers.example.com[192.168.42.15]:24, delay=61, delays=0.02/0.3/31/30, dsn=4.4.0, status=deferred (host loadbalancers.example.com[192.168.42.15] said: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) It's a bit unclear to me if this leads to duplicate deliveries, or just delayed deliveries, but -- is there any way to limit the number of simultanous deliveries on either the dovecot director or the backend lmtp-servers ? Will "process_limit=10" work for "service lmtp"? -jf
