[Dovecot] Seen flag getting lost
by Edgar Fuß 26 Nov '11

26 Nov '11

We have two dovecot 1.2 instances sharing Maildirs on NFS. Indexes are local to the individual servers. Occasionally (no idea how to trigger this), the Seen flag gets lost on some messages. I've verified that actually the ``S'' is missing from the filename. I suspect something like server A caching the flags, server B setting Seen, and then server A flushing its cache for another change so overwriting what B changed. Any ideas short of switching to 2.0?

[Dovecot] v2.1.rc1 released
by Timo Sirainen 25 Nov '11

25 Nov '11

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz.sig I'll probably release v2.1.0 pretty soon, unless people report some new bugs. I know v2.1 is already being used to serve mails to tens (or hundreds?) of thousands of users, so it should be pretty stable. Most of the changes since v2.1.beta1 have been for rather small issues. Many of the fixed bugs exist also in v2.0, but since they are so minor I didn't bother backporting the fixes. As new features since v2.1.beta1 there are the things I did also for v2.0.16, and: * ssl_client_cert/key: Proxying can now send SSL certificate to backend server * ssl_crypto_device for enabling hardware encryption * SCRAM-SHA-1 authentication mechanism support by Florian Zeitz * passdb/userdb checkpassword: Export all auth %variables to AUTH_* environment. * maildir_broken_filename_sizes setting for people upgrading from other maildir servers that wrote tons of broken S=<size> values And as a reminder, here are the biggest new things since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] How to create home directories for virtual users?
by Olli Räisänen 25 Nov '11

25 Nov '11

Hello, I,m using Dovecot 1.2.9, now finishing a migration from Courier IMAP. Documentation (http://wiki.dovecot.org/VirtualUsers/Home) says that home directory should not be the same as mail directory. When I create new user accounts with PostfixAdmin the mail directory is not a problem but is there some smart way to create the home directory as well (locating it for instance in '/srv/vmail/%d/%n/home')? Regards, Olli

[Dovecot] Problem with lmtp proxy
by Miguel Tormo 24 Nov '11

24 Nov '11

Hello everyone, I have set up postfix to deliver mails to dovecot (2.0.16) using LMTP. On the other hand, I've successfully configured the IMAP proxy setting in dovecot in order to be able to distribute mailboxes among different servers. I wanted to do the same proxy at LMTP level, but it's not working. If I put lmtp_proxy = no, then everything works ok (assuming the mailbox is local), but when I set lmtp_proxy = yes then the user is not found when deliverying the message via LMTP, so the mail remains in the postfix queue. Users are validated through active directory. However, this AD hasn't the SFU installed, thus its LDAP schema doesn't provide me with the required uid, gid, etc. To solve this, I have winbind configured in the system, so I'm doing this: - To validate users *and* be able to set the proxy extra fields, I use ldap as "passdb" (I believe it's not possible to use proxies with PAM). I'm using some LDAP field to store the host that has the user's mailbox. - In order to get the user account data that is not available in the AD, I use passwd as "userdb". I know that when using LMTP with proxy, a passdb needs to be configured. I assume this is needed for the service to lookup for the appropriate host to send the message. So, initially I set ldap as the passdb for LMTP, but just because it didn't work I put both ldap and passwd, and even a userdb (passwd), but the problems remain the same. Anyway the ldap should be the right one as it is there where I have the host information for each user. I think I'm missing something but I can't find what it is. To summarize: with lmtp_proxy = no it does work, with lmtp_proxy = yes it doesn't. Thank you for your help!

[Dovecot] modules directory
by Johannes Berg 24 Nov '11

24 Nov '11

Hi! I'm a little confused with how plugin loading works in dovecot 2, I can't seem to make it load from $(moduledir)/imap/. Is that intended to work? Just a configuration issue? Reason I ask is that I ported my antispam plugin (I know there's a fork, but I still like mine better) to dovecot 2 and the default "make install" no longer loads properly with just "mail_plugins = antispam". So is $(moduledir)/imap/ no longer used? I also notice acl/imap_acl now, but I still see subdirectories for at least auth. Should I install into just $(moduledir)/ now? johannes

Re: [Dovecot] Solaris hardware crypto engines
by Martin Preen 24 Nov '11

24 Nov '11

Hello, after serveral tests (and reading a lot of howto's) I'm now fairly convinced that the Solaris HW-crypto engine is not automatically used. Even when dovecot ist compiled with the OpenSSL version provided by Solaris. Currently I have only a T1-CPU available for testing (Sun Fire T2000) and after patching src/login-common/ssl-proxy-openssl.c (Dovecot 1.2.17) with ENGINE *e; ENGINE_load_builtin_engines(); ENGINE_init((e=ENGINE_by_id("pkcs11"))); ENGINE_set_default_RSA(e); ENGINE_set_default_DSA(e); ENGINE_set_default_ciphers(e); in ssl_proxy_init() and inserting ENGINE_cleanup(); in ssl_proxy_deinit() the crypto device gets used. I'm sure that this is not the whole story since this only seems to affect the IMAP login. One has to use the specific SSL-engine and the ENGINE/EVP calls (as stated in the various articles). Is there any chance that Dovecot gets updated/patched for this ? E.g. Like the SSLCryptoDevice setting in Apache's mod_ssl. Regards.

[Dovecot] seting acl for master user?
by oni-neko＠gmx.net 24 Nov '11

24 Nov '11

Hello! I'm sorry, but i don't really understand it the way it is written in the wiki, so i'm trying my luck here =) i followed the wiki for creating a master user (the non-sql-version) and i can login as another user via this master user. my dovecot version is 1.2.9 on an ubuntu server 10.4.3 lts. what i don't get is the acl-setting, so that the master-user can access all the other users mails and folders. i made the changes in the dovecot.conf as written in the wiki: protocol imap { mail_plugins = acl imap_acl } protocol lda { mail_plugins = sieve acl } plugin { acl = vfile:/etc/dovecot/acls } in my case I only want the master user (called cyrus) to be able to do everything with/in all mailboxes, so I made a file /etc/dovecot/acls/default that reads "user=cyrus lrwstipekxa". i'm pretty sure i'm missing something rather obvious here, but somehow i'm just stuck. any help would be greatly appreciated. thanks in advance =) silvana -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!

[Dovecot] Random Loss of Connection with Thunderbird and Dovecot
by Jay Welch 24 Nov '11

24 Nov '11

Hi, Dovecot Version: 1.2.16 OS: CENTOS 5.5 I am having issues with Thunderbird connecting to Dovecot at random times. Usually an error comes up and states that Thunderbird cannot connect to the server. The only way I have been able to fix this is reset/repair the network connection or reboot the computer. Is there any parameters I can change in Dovecot to fix this issue? Does anyone know what is likely going on? I have been reading forums and I cannot find anything. Thanks

[Dovecot] Excluding some system users after configuration
by Nanitous 24 Nov '11

24 Nov '11

Dear readers, Consider an installed Postfix configuration (2.3.3) on CentOS. Now I want to install Dovecot (alas only version 1.0.7.7 is available) to provide IMAP services for a few system users, but not all. Most importantly the mail delivery by postfix for some of these system user /must/ not change after the installation of Dovecot. How can I prevent the installation of Dovecot to touch some specific system user accounts? Thanks in advance, /Twan

[Dovecot] How to disable pop3 in version 2?
by Knute Johnson 24 Nov '11

24 Nov '11

I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports? And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps? Thanks, -- Knute Johnson

[Dovecot] 1.2.15 can't get zlib working
by Stan Hoeppner 24 Nov '11

24 Nov '11

Following these instructions: http://wiki.dovecot.org/Plugins/Zlib I enabled zlib and restarted Dovecot. I made a backup copy of a 68MB mbox file and moved it to a non mail directory. The mbox file is an existing TBird IMAP folder in my UNIX user mail directory. It is an archive of a defunct mailing list. It was a regular IMAP folder prior to attempting this. I was able to access all emails in the folder. It worked fine. I gzipped the original mbox file down to 14MB and removed the write flag with chmod. I launched TBird and received the following error in Activity Manager when accessing this IMAP folder: The current operation on '1-Spam-l' did not succeed. The mail server for account stan(a)hardwarefreak.com responded: Mailbox doesn't exist: 1-Spam-l I deleted the Dovecot index files and the TBird 1-Spam-l.msf file which didn't help. Curiously, there are no entries in either dovecot.err or dovecot.log, giving not even the slightest hint as to where I should troubleshoot. Kinda sucks when one follows instructions exactly, simple instructions at that, and it doesn't work, and generates zero log errors. A bit frustrating...

[Dovecot] v2.1.beta1 released
by Timo Sirainen 23 Nov '11

23 Nov '11

http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz.sig Here's the first beta release of Dovecot v2.1. This version has already been tested quite a lot, so I'm not expecting any major bugs. So please upgrade and see if you can find any problems. I'm optimistic about getting rc1 released this year and perhaps even v2.1.0. Since alpha2 there have been a lot of fixes, especially to imapc backend. There are probably also some small new features, but nothing huge. As a reminder, here's the largest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] dovecot as an imap "client"

[Dovecot] [PATCH] SCRAM-SHA-1 authentication
by Florian Zeitz 23 Nov '11

23 Nov '11

Hy, over the last days I have implemented SCRAM-SHA-1 in Dovecot's 2.1 branch. It does not do SCRAM-SHA-1-PLUS, but should be extendable enough to introduce it later. There are some checks for the message format which (assuming the client acts correclty) are not strictly necessary during parsing. This is partially in the hope that it might aid client implementers, partially because it (IMHO) improves readability when checking against the RFC. Also errors found in this way could be sent to the client, this is however strictly OPTIONAL in the RFC, for now they are just logged. Some of the variable names are rather long. This is in order to have them match the terms introduced in the RFC, again I expect it to help readability (maybe my recent Objective-C programming showing though). I do feel somewhat insecure about my usage of some lib functions. Hopefully no API has been abused too much. I also note that there are a lot of fields in the scram_auth_request struct. I think they are all there for a reason, however feel free to prove me wrong. Attached is a hg export. It also includes a hmac-sha1 implementation, an adaption off of the hmac-md5 implementation already in Dovecot. I guess those should eventually be merged into a hash-independent hmac implementation, but I figured this would have to do for now. The implementation has been tested against GNU SASL and does appear to work fine. (The command line was `gsasl -m SCRAM-SHA-1 -a user -p pass --imap host` for those curious) Regards Florian "Florob" Zeitz

[Dovecot] Can't delete sub-folder
by pch0317 23 Nov '11

23 Nov '11

Hi list, I have problem with deleting sub-folder. I use thunderbird 8.0 as a client and dovecot 2.0.9 with imap protocol as a server. I use dovecot with tb-extra-mailbox-sep parameter. I use mbox mailboxes and thunderbird with *not checked* option 'server supports folders that contain sub-folders and messages' so when I create sub-folder I can choose between 'folders only' and 'messages only'. When I try to delete 'parent' folder which contain 'messages only' folder, error message appear: [ALREADYEXISTS] Mailbox has children, delete them first. Ok, so I delete 'message only' folder first and try to delete parent folder, but the same error appear: [ALREADYEXISTS] Mailbox has children, delete them first. When I list mailboxes from console I see inside 'parent' folder ".imap" folder. When I delete .imap folder from console and then delete parent folder from thunderbird, parent folder is deleted correctly. Which application create this ".imap" hidden folder and how solve this problem. Thanks

[Dovecot] Unique message IDs?
by Alexander Chekalin 23 Nov '11

23 Nov '11

Hello, I'm working with indexing my mail box. What I need is to have index in which mailing specified header string is located. I work with the messages via IMAP. I know that sounds like FTS can help me but no, I don't want to index whole message nor I want to patch FTS source to make it to index headers only. I need a way to identify message across my mail box. The idea is that I can move messages between IMAP folders and the index still should be able to identify it. What I want to know, will UID strings be unique across all my messages no matter which IMAP folder it belongs now to, or the UID can change if I move message? If I remove dovecot-uidlist from the folder will UIDs of messages in the folder be changed? What happened if I put a message to the given IMAP folder (and dovecot-uidlist will record UID for it), then shut down dovecot, and (given maildir storage model) move the message's file info another folder in the same mail box - after I start dovecot, will the UID for the message be the same or not? Thank you in advance, Alexander Chekalin

[Dovecot] dsync strange duplicate directories
by Frank 23 Nov '11

23 Nov '11

Hello, i'm testing whether dsync will help me in setting up a redundant master - master imap setup and experience this: 1. Master 1 dovecot is running, master 2 dovecot is down 2. I use rsync to create an exact copy of the master 1 maildir on master 2 3. I start up master 2 dovecot 4. I do a dsync on master 2: dsync -D -u test(a)example.com mirror ssh root@master1 dsync -D -u test(a)example.com Now what i see is this: Each mail directory is duplicated on master 1 and master 2 to a directory name with some MD5 hash value (as it seems) e.g. before dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Junk .Sent ... after dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Drafts_af61060f6f9fcb4efc0a00002691362e .Junk .Junk_b261060f6f9fcb4efc0a00002691362e .Sent .Sent_b261060f6f9fcb4efc0a00002691362e ... The new directories contain the same files as the original directories. What am i doing wrong? Thanks for the help Frank

Is there a way to disable the imap info logging? My logs are filling with tons of login/logout messages Nov 22 18:23:25 imap-login: Info: Login: user=<USER1>, method={method}, rip=10.86.189.79, lip=10.86.189.82, mpid=22488 Nov 22 18:23:25 imap(USER1): Info: Disconnected: Logged out bytes=54/726

[Dovecot] No duplicates on imap copy?
by Alexander Chekalin 22 Nov '11

22 Nov '11

Hello, when from my script I try to copy messages from one imap folder into another own (within the same imap mailbox). That works perfectly, but... If I copy the same message N times from one folder into another one, in the destination folder I see N copies of the same message, each with its own UID. I wonder if there any way to deduplicate folder content (so in the destination folder I'll get only one copy of each message)? I'd implement something like that myself in my script but I just don't know which part of the messages should I compare - probably md5 of headers? Thank you in advance! Yours, Alexander Chekalin

[Dovecot] Dovecot Log analysis
by Thomas Hummel 21 Nov '11

21 Nov '11

Hello, Before writing them myself, I'd like to figure out if some tools exist (anvil ? ...) and how to use them to extract from dovecot logs things like who is doing what and how hard or how fast in order to do some rate limiting. For instance, I'd like to be able to identify, slow or block users who . read or write to much / slice of time . login/logout too often / slice of time Note : I'm still using the 1.2.x branch.

[Dovecot] Dovecot performance issues with many writes
by Andy Robbins 21 Nov '11

21 Nov '11

We are currently experiencing performance issue with our Dovecot system which we believe is caused by excessive writes to the dovecot files. The confusing thing is that we are seeing more writes than reads on our Dovecot volume when you would assume that most of the IO should be reads from customers checking their mail. We're seeing reads vs. writes similar to the following: # iostat -d 5 -x Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util dm-4 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 28.69 19.63 0.70 94.00 drbd0 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 111.42 94.44 0.74 99.60 We can't figure out why we would be seeing twice as many writes as we are reads. Could this have something to do with the index files? Appreciate any assistance on this issue.

[Dovecot] Question about imaps
by jgiles＠cybermesa.com 21 Nov '11

21 Nov '11

Hi List! Had a questions about imap vs. imaps. I read the ssl article at http://wiki2.dovecot.org/SSL and from what I am reading, imaps is no longer needed as imap with initiate SSL/TLS on its own if STARTTLS is started and I have disable_plaintext_auth=yes and ssl=required settings. I do have SSL up and working, and can connect using imap (143) to my server without issue, but was not able to connect using imaps (993) using Kmail as my client. I Was getting a client error stating that the authentication failed using my password. However, there was nothing in the mail.err or mail.log file even when I enable debugging. If I specify imaps as my only protocol, then dovecot fails to even start without any error loging at all. As I stated, imap works just fine. So, is imaps deprecated as mentioned in the article and imaps no longer needed? I am running Dovecot 2.0.13 on an Ubuntu 11.10 64bit server. This server is simply an imap serer and not a MTA (No postfix or sendmail installed.) Thanks! Joe

[Dovecot] issues with 2.1b1 on OS X
by metro_domain_admin＠fastmail.fm 21 Nov '11

21 Nov '11

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html) I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically: #NOPLUGIN_LDFLAGS="-no-undefined" if test "$with_gnu_ld" = yes; then NOPLUGIN_LDFLAGS="$NOPLUGIN_LDFLAGS -Wl,--as-needed" fi More important, Dovecot aborts on launch with the following error: Nov 19 10:23:52 kerio2 dovecot[33553]: master: Fatal: kevent(EV_ADD, READ, 16) failed: Invalid argument I configured using the same args as I had used successfully on 2.0.15: --with-gssapi --with-ldap --with-sql --prefix=/opt/dovecot-2.X.X. I also tried an exact copy of my known-good config from 2.0.15, to no avail. Thanks, Tony

[Dovecot] Released Pigeonhole v0.2.5 for Dovecot v2.0.16
by Stephan Bosch 19 Nov '11

19 Nov '11

Hello Dovecot users, Before I move active development of Pigeonhole to Dovecot v2.1, I first release all the pending bug fixes and small improvements. Changelog v0.2.5: + Sieve vacation extension: made discard message for implicit delivery more verbose - The sieve-test tool: mixed up original and final envelope recipient in implementation of command line arguments. - Sieve vacation extension: resolved FIXME regarding the use of variables in the :handle argument. Variables are now handled correctly. - Sieve body extension: fixed handling of :content "message/rfc822". This now yields the headers of the embedded message as required by the specification. Handling of :content "multipart" remains to be fixed. - LDA Sieve plugin: fixed problem with recipient_delimiter configuration. Now it falls back to global recipient_delimiter setting if plugin/recipient_delimiter is not set. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Mail_quota plugin and LDAP on Dovecot 1.2

In logs nothing happens the configuration in dovecot.conf below protocol imap { mail_plugins = quota imap_quota } protocol lda { mail_plugins = quota } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } the configuration in dovecot-ldap.conf below uris = ldap://server-ldap.com.ve auth_bind = yes ldap_version = 3 base = dc=dominio,dc=com,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota=dirsize:storage user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) This is the same configuration in the 6 last years.

[Dovecot] dsync problems
by Micah Anderson 17 Nov '11

17 Nov '11

When a user renames their username, I am using dsync to copy their mail over to the new username's mail location[0]. Some of the dsyncs are failing with errors that I dont know how to work with, for example: dsync(<username>): Error: Trying to open a non-listed mailbox with guid=41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: msg iteration failed: Couldn't open mailbox 41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=42fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=43fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=44fcd40303c8a64e432300007ef44c7a ERROR: dsync failed, exit code: 256 The errors cause a non-zero exit code from dsync, which causes my rename script to bail out. What are these errors, and how can I fix them? Thanks, micah 0. Why use dsync instead of a simple mv operation? This seems to be necessary for two corner cases: 1. dovecot creates the new mailbox automatically when the user logs in or receives a mail, so if the user changes their mail and logs in or receives an email before the move has been done, then the mailbox is created and then a move command will fail. 2. If there has been new mail created under the new name, we can't just simply remove the stuff that is automatically created there and replace it with the old things because we could potentially be removing mail that has been delivered in the mean time. I'd be really interested if people had suggestions for a better mechanism, or perhaps a way to have dovecot not create the new mail location automatically. --

[Dovecot] 2.1: virtual plugin and lsub
by e-frog 17 Nov '11

17 Nov '11

Hi Timo, I'm using the virtual plugin and have 2 mailboxes configured in the "virtual" namespace (dovecot -n attached). Using lsub with dovecot 2.0.15 leads to the following result: 1 lsub "" "virtual/*" * LSUB () "/" "virtual/Lists" * LSUB () "/" "virtual/unread" 1 OK Lsub completed. However with dovecot 2.1 (latest hg as of today) and the same config there is a 3rd mailbox "virtual" listed which doesn't exist: 1 lsub "" "virtual/*" * LSUB () "/" "virtual" * LSUB () "/" "virtual/Lists" * LSUB () "/" "virtual/unread" 1 OK Lsub completed. Thunderbird shows the "virtual" mailbox as selectable and not grayed out as with 2.0.15. Clicking on that mailbox gives an error message "Mailbox doesn't exist: virtual". Thanks, e-frog

[Dovecot] Performance-Tuning
by Peer Heinlein 17 Nov '11

17 Nov '11

Hi, I have > 11 TB hard used Mailstorage, saved als maildir in ext3 on HP EVA. I always wanted to make some mesurements about several influences to the performance (switch to ext4, switch to mdbox), but I never had enough time to do that. At the moment I *need* more speed, we have too much waitI/O on the system and I already used all other performance and tuning-tricks (separated cache, noatime, fsync and all that stuff). I have to change my setup, maybe somebody else here have hard facts: *) Is ext4 faster? How much faster? *) Is it faster because of the ext4 kernel-module (which can be used on ext3 to) or because of the ext4 filesystem layout? *) Is mdbox really faster? I'd like to have mdbox to have better performance in running my backup-processes. But does it bring some performance boosts to?

[Dovecot] Port variable in LMTP userdb lookups?
by Mark Zealey 17 Nov '11

17 Nov '11

Hi all, I'm currently changing some systems to use the redirector service, which means that to get local deliveries going I need to get lmtp set up so it can be redirected as well. This is working fine, however we have a number of different ports running on our servers depending on which brand a customer is using. When the time comes to do the user look up, we use (port, user, domain) to do a unique database lookup which works fine for everything (proxied pop, imap, lmtp & straight pop, imap) but not straight lmtp - perhaps because it doesn't have a 2-stage login process unlike the pop/imap protocols. Looking at the SQL query we are issuing, the %a port variable is set to 0 even though the connection is coming in from TCP. Is there a way to change this? We are running dovecot 2.0.12 however looking through the changelogs I can't see this would be fixed in the newest version. Thanks, Mark

Re: [Dovecot] Please advise on very fast search
by Alexander Chekalin 17 Nov '11

17 Nov '11

Thanks, Robert, will take a look at. What I'm afraid for is how database storage should be planned (storage, CPU, RAM, scaling when will be over-filled). When dealing with files (I'm using maildir), it is much easy to understand and to fix just about everything. Adding database involves tune it up too, and I'll have more points of 'tune it a bit' In fact work with Dovecot is pretty nice, but I think I can tune it to work faster. I now run it on FreeBSD (on UFS2), maybe I should change OS + FS, but need to test (really hope ZFS disks on SAS drives will help; still find no benchmarks on such a setup). Will also try to use full text search, but afraid of index size (and I need no search on body, just on headers). Anyway thank your for pointing me in right directions! Yours, Alexander

[Dovecot] Getting started with sieve and conversion from procmail
by Alex 17 Nov '11

17 Nov '11

Hi, I have a fedora15 system with dovecot-v2.0.15, dovecot-pigeonhole and and amavisd-new and would like to implement it on my system using postfix. I've read the basic wiki documentation, but I really can't figure out the proper starting point in my case. I've enabled "protocol lda" in 15-lda.conf and added "sieve" to the list of mail_plugins. I'm trying to adapt postfix to use deliver as its LDA for multiple virtual domains. I've added the following to master.cf: dovecot unix - n n - - pipe flags=DRhu user=dovecot:dovecot argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient} -a "${RECIPIENT}" Is that the proper format? Is it okay to use the dovecot user here, or should I create a new user? What permissions does this user need to possess? I've added the following to main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot I have a number of procmail scripts and I've converted them to sieve, but they didn't convert very well. Can someone show me how to convert the following: :0 { :0 fhW | /home/alex/bin/process-mail.pl } The script skipped right over that. I'm also trying to convert the following: :0 * (RCVD_IN_DNSWL_HI|RCVD_IN_DNSWL_LOW|RCVD_IN_HOSTKARMA_W) * !USER_IN_WHITELIST * !BAYES_00 * !URIBL_ * !KHOP_RCVD_UNTRUST * !RCVD_IN_DNSWL_MED * !SPF_SOFTFAIL * SPF_HELO_PASS * SPF_PASS { LOG="DNSWL: " :0: whitelist/dnswl } The script only produced the following: if true { if true { if true { if true { if true { if true { if true { if true { if true { if true { fileinto "{"; fileinto " LOG="DNSWL: ""; fileinto " :0:"; fileinto " whitelist/dnswl"; fileinto "}"; } Any ideas greatly appreciated. Thanks, Alex

[Dovecot] v2.0.16 released
by Timo Sirainen 17 Nov '11

17 Nov '11

http://dovecot.org/releases/2.0/dovecot-2.0.16.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.16.tar.gz.sig I only now noticed that the VSZ limits weren't being enforced with earlier v2.0.x releases (or they were set 1024 times too high). So if a Dovecot process was leaking memory, it wasn't being killed by kernel. Now that this enforcing is done, some installations will probably start seeing errors about reaching these limits in normal operation. The default_vsz_limit is 256 MB. You may want to increase it in larger installations to 1 GB just in case. Besides the changes listed below, a lot of smaller fixes were done. v2.0.16 2011-11-17 Timo Sirainen <tss(a)iki.fi> * VSZ limits weren't being enforced for any processes. On server with large mailboxes you may now see errors about it if the limits aren't high enough. To fix them, either increase individual service { vsz_limit } values or simply increase the default_vsz_limit setting. * Proxying: If using ssl=yes or starttls=yes with a hostname (not IP) as proxy destination, require that the certificate matches the given hostname. * LMTP: Changed default client_limit to 1. This should improve LMTP throughput with default settings. * dsync: Quota is no longer enforced (i.e. dsync can't fail because user is over quota). + Added "auto" mail storage driver, which can be used to autodetect mailbox location and format. This behavior is already the default for empty mail_location setting, so this change is mainly useful for shared namespace's location setting. + checkpassword: Export all auth %variables to AUTH_* environment.

[Dovecot] Bus factor of dovecot / GIT
by Thomas Koch 17 Nov '11

17 Nov '11

Hi, somebody from the kolab groupware project recently explained me that the Bus- Factor[1] of around 1 would be one of their primary reasons not to use Dovecot and stick with Cyrus. What do you think about that? Is the bus factor much higher then 1? [1] http://en.wikipedia.org/wiki/Bus_factor Somehow related: Since the free software world[2] slowly converges towards GIT as the "one and only" VCS, have you thought about a switch? It's much more likely that somebody checks out your code, looks into it and provides patches if the VCS is already installed.

[Dovecot] Glued-together private namespaces
by Mark Moseley 16 Nov '11

16 Nov '11

I've been goofing with this all day with 2.0.15 and I'm starting to realize that either a) I'm not that smart, b) it's been so long since I messed with namespaces that I'm going about it completely wrong, or c) it's just not possible. I haven't posted 'doveconf -n' and other details, because mainly I'm just looking for 'yes, this is possible' or 'no, you're smoking crack' before posting further details. At this point, it's all maildir and moving to mdbox, while highly desirable in the future, is not possible in the near- to medium-term. I'm trying to glue a namespace underneath INBOX: namespace INBOX { type = private separator = . prefix = INBOX. # Yes, this used to be on Courier inbox = yes list = yes hidden = no subscriptions = yes location = maildir:~/Maildir } namespace archive { type = private separator = . prefix = INBOX.Archives. inbox = no list = children subscriptions = yes location = maildir:~/Maildir-Archive } I've tried putting namespace archive's 'prefix' as just "Archives", but Tbird doesn't seem to see this namespace, regardless of how much I futz with the imap settings in tbird. With the above setup, it actually seems to work correctly (provided ~/Maildir-Archive exists), though I'm sure a big gotcha is waiting in the wings. I can move messages around, create subfolders, subscribe to folders in ~/Maildir-Archive). The only thing I can't seem to get working is quotas. With my password_query like: password_query = ... CONCAT( '*:bytes=', "1M" ) AS 'userdb_quota_rule', \ CONCAT( '*:messages=10' ) AS 'userdb_quota_rule2', \ CONCAT( 'INBOX.Archives:bytes=+4900M' ) AS 'userdb_quota_rule3', \ CONCAT( 'INBOX.Archives:messages=+3900' ) AS 'userdb_quota_rule4' ... only the default quota seems to be in place for any subfolder of INBOX.Archives and for INBOX.Archives itself, i.e. *:bytes still applies to INBOX.Archives. The debug log show that: Debug: Quota root: name=User quota backend=maildir args= Debug: Quota rule: root=User quota mailbox=* bytes=1048576 messages=0 Debug: Quota rule: root=User quota mailbox=* bytes=1048576 messages=10 Debug: Quota rule: root=User quota mailbox=INBOX.Archives bytes=+5138022400 messages=0 Debug: Quota rule: root=User quota mailbox=INBOX.Archives bytes=+5138022400 messages=+3900 These are wildly stupid quotas but they're just there to test. With INBOX already at capacity (byte-wise; only set to a meg), copying large messages inside INBOX.Archives fails (only copying a 800k message but the quota should be 5gig now). Again, before I post configs, I'm just curious if what I'm trying to do isn't remotely possible, or that I'm approaching this entirely wrongly. Thanks!

Re: [Dovecot] Seg fault in dovecot/auth 2.0.15

Your message was discarded by mailman, probably because it was html-only. Anyway: On Wed, 2011-11-16 at 13:15 -0500, Mark Goldey wrote: > (gdb) p *auth_request->userdb->userdb->iface > $2 = {name = 0x807023e "vpopmail", preinit = 0x8065d60 > <vpopmail_preinit>, init = 0, deinit = 0, > lookup = 0x8066010 <vpopmail_lookup>, iterate_init = 0, iterate_next > = 0, iterate_deinit = 0} OK, so "auth_request->userdb->userdb->iface->lookup" should call vpopmail_lookup(), it's not NULL as this says: > > (gdb) bt full > > #0 0x00000000 in ?? () So something's going strangely wrong. Maybe gcc optimizations cause this and the real problem happens later. Try compiling auth process with optimizations: - Remove -O2 from src/auth/Makefile - cd src/auth ; make clean ; make ; make install Is the backtrace different?

Hi i am using dovecot 2.0.13 and i can't see public folder in my mail client. But what is strange, it was working after instalation, and i don't know when it dissapeared. Maybe after some upgrade ? When i enable debug, then i can see in my log that folder exists and no errors. Please where should i find the problem ?
