[Dovecot] Quota plugin
by Thiago Monaco Papageorgiou 22 Aug '08

Hi! I have some questions about quota plugin. I have taken quota-maildir as example. What does the function maildir_quota_root_get_resources? When it is called? I have tested including some log messages, but it wasn't appears in the log file. When dovecot calls this function? It is an important function?

by Mikael Jenkler 21 Aug '08

21 Aug '08

Hi All! There is a issue with dovecot-antispam and the new dovecot-1.1.x (dovecot-1.1.1) The imap server dies when sending mail, the mail goes away but it says that the imap server has crached in squirrelmail. I get the standard signal 11 crach in the dovecot loggs another question? My dspam users has the email as username somthing(a)domain.com and in dovecot.conf i need to specify the user when training, is there a w way to get the resiptient address in the dovecot.conf? i am only able to get %u ie the username ;-( Could you patch the antispam plugin to be able to take then resiptient as dspam user? ie the mail address , you can have a option in dovecot that says use resiptient address as user or something it would be great if you had time to check this out ;-) Thanks in advance

[Dovecot] Sent Date/time vs Received Date/time

I know that every message has a 'received' header, which is basically the date/time stamp of the SENDERS CLIENT - so if their system's time is off, that date/time header will be off. So, where does this 'Order Received' column in TBird get its info from? I'm guessing it is a TBird thing, like an internal index number? In my mind, there should be two primary date/time columns: Sent Date/Time = Date/time of the Client system when message was sent (this is already there as the plain 'Date' column) and Received Date/Time = Date/time the receiving SERVER DELIVERED it I can see the benefit for the third 'Client' side Date/time stamp, which is the current 'Order Received' in TBird. I'd like to see support added for grabbing the last date/time from the LDA that delivers the message, but that obviously request is for the TBird devs (or most likely an extension request), but... The main question is - is there a proper IMAP/RFC for providing/getting this date/time? -- Best regards, Charles

I sort by arrival time, which in practice is the "unsorted" ordering based upon the mbox file itself.

[Dovecot] Dovecot & (Al)pine - resaving messages to Inbox
by Jonathan Herbach 21 Aug '08

21 Aug '08

I have a x86 Linux box running Fedora 4. Up until 2008 I was using pine 4.64 and Dovecot 0.99.x. In early 2008 I transitioned to Alpine 1.10, and didn't notice any major changes. I upgraded to Dovecot 1.0.15 this past weekend. My dovecot -n settings are at the bottom of the email. I've noticed a change since Dovecot was upgraded. I used to reorder items within my INBOX in al/pine by "saving" messages back to the INBOX, which I was connecting via IMAP . Now when I try to do it I get an error in alpine that says: [Can't copy mails inside same folder] then: [Save to folder "{localhost:143/i...r=jherbach}INBOX" FAILED] While these are alpine messages, they appear to be from the dovecot upgrade. I really miss the ability to reorder messages in my inbox since I often use it as a queue of important items. Does anybody have any ideas why I'm seeing this error message? Or better yet, how to potentially (re) configure the system to allow me to resave messages into the same folder?

[Dovecot] config file parsing, tab characters
by John Hannfield 21 Aug '08

21 Aug '08

Hello, I am using the latest dovecot 1.1.2 with postfix, and using doveco deliver command for LDA. I really love dovecot, and how it has progressed over the years. However I have noticed that if I put a TAB character in the dovecot.conf file, it sometimes does not parse the file correctlty, and complains about missing postmaster_address etc, even though they are there. So I reformated my config file, with just spaces, no tabs. I am very careful about that now. However I still seem to have a problem in some places with spaces. For example, in the LDA section: If I have 3 or 4 spaces, after the lda line in the definition, like so: #----------------------------------------------------------------------------- # LDA Settings #----------------------------------------------------------------------------- protocol lda { postmaster_address = postmaster(a)mydomain.com hostname = mydomain.com .... it does not work. I must have only 1 space between the end of lda and the curly bracket. Like this: #----------------------------------------------------------------------------- # LDA Settings #----------------------------------------------------------------------------- protocol lda { postmaster_address = postmaster(a)mydomain.com hostname = mydomain.com .... This seems very flaky. I am not certain I will always be able to check the file when making changes. So my question is: 1. Is there someway to check the validity of the dovecot.conf file. I notice dovecot -n does not print the entire config. 2. Is there any chance the code used to parse the config file, could be updated to be more robust, and to include support for tabs? Thank you.

[Dovecot] How Can I Tell How Dovecot Was Installed?
by Blake Carver 20 Aug '08

20 Aug '08

I'm trying to help someone with Dovecot, and it looks like this one is a few versions behind. They say that they're not sure if it was installed Via an RPM or a source tarball. Dovecot is use MySQL. This is a RHEL5 server. There are RPMs listed as installed (rpm -qa) but I don't know how I can tell what was used to install the currently used set up. (also asking on the Postifix list) Is there something in a conf file or something that shows me how it was installed? Thanks Blake

[Dovecot] Stateful Webmail

20 Aug '08

Hello, I'm a developer on the Orbited project (http://www.orbited.org) which provides a TCPSocket interface in javascript (emulated over HTTP using ajax and comet.)

Coincidentally, we have just began work on a JavaScript IMAP client. With it, building a webmail app should be *entirely* a UI concern. The good news is that our Socket interface is very stable and is being used in production for protocols like IRC for webchat. The bad news is that none of the the Orbited developers have experience with the IMAP protocol. We are putting all of our protocol implementations in the soon-to-launch js.io project (www.js.io) As soon as we have any kind of IMAP client prototype, I'll let you know. In the meantime, would anyone be interesting in helping us develop the imap client? Its 100% pure JavaScript, and will greatly ease the development of feature-rich webmail, as a webmail deployment will become a matter of simply running Dovecot, the js.io.imap client, and an HTML gui. -Michael Carter

[Dovecot] dovecot performance
by Giorgenes Gelatti 19 Aug '08

19 Aug '08

Hello All, I've been studying dovecot for replacing my company's current system and I got a little worried about an aspect of the dovecot's design. I was surprised that dovecot doesn't use prefork for its mail processes, forking a new processes for each new client connection. Talking in the #dovecot channel I was gave a scenario of a system supporting ~40k users with 4 servers just fine. I wonder how well dovecot would scale if we increase this number of users by some order of magnitude like, say, 4M users. It is well known that preforking is a good pratice if you want to achieve a higher performance. When I was asked about it I readily answered: "of course it does". For my surprise later, i doesn't. Do you have any plans to support preforking in the near future? Best regards, giorgenes

[Dovecot] dovecot: Fatal: Time just moved backwards by 3603 seconds.
by Stephen Feyrer 19 Aug '08

19 Aug '08

<nervous_darting_eyes> Hi Everyone. </nervous_darting_eyes> Ooops I just broke my dovecot install. I've looked through the mailing list archives and not found anything relevant. When I try to connect to my mail server I get this message. "Could not connect to mail server chen.home.org; connection was refused" The last message in /var/log/mail.err is:- Aug 13 21:02:27 chen dovecot: Fatal: Time just moved backwards by 3603 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards It seems this is my own fault. Time on my system is a little wonky so I reset the time and then I found out I'd broken Dovecot. I didn't realise that doing this would have an impact on dovecot. I read the web page and to be honest I'm not confident about hacking source code. I've reinstalled dovecot which worked except it hasn't solved my time travel problem. By the way since my first install of dovecot the config file seems to have changed a little but since I've tried to migrate my settings over the new file and been met with the same problem I don't think it's that. Is it possible to get dovecot working again? -- Regards Stephen.

A patch has been proposed for SpamAssassin to process Maildir folders of spam: <https://issues.apache.org/SpamAssassin/show_bug.cgi?id=3003> Is this patch compatible with Dovecot's implementation of Maildir? For example, is anything needed to avoid stepping on Dovecot's metadata?

[Dovecot] POP3 dictionary attacks
by Kenneth Porter 18 Aug '08

18 Aug '08

I'm seeing strings of failed POP3 login attempts with obvious bogus usernames coming from different IP addresses. Today's originated from 216.31.146.19 (which resolves to neovisionlabs.com) This looks like a botnet attack. I got a similar probe a couple days ago. Is anyone else seeing these? The attack involves trying about 20 different names, about 3-4 seconds apart. Here's a few sample log lines: dovecot: Aug 15 04:15:45 Error: auth-worker(default): pam(mike,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:49 Error: auth-worker(default): pam(alan,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:53 Error: auth-worker(default): pam(info,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:57 Error: auth-worker(default): pam(shop,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module Timo, can you add the port used in the attempt to the error log entry? (It does show up in the info log entry, but that means I need to correlate lines in the two log files.)

[Dovecot] IMAP maildir performance difference between dovecot-uidlist versions?
by Jack Stewart 17 Aug '08

17 Aug '08

Hi, Is there an IMAP performance difference using Maildir between using version 3 and version 1 of the dovecot-uidlist (either dovecot 1.0.7 or 1.1.2)? It isn't entirely clear to me there is any difference as the filename may contain the size/vsize information. The servers will eventually be running 1.1.2 with the maildir_copy_preserve_filename turned on. I'm doing a batch migration from courier to dovecot 1.0.7 and eventually dovecot 1.1.2. These servers are, and will continue to be, IMAP only (i.e. dedicated control/dovecot-uidlist files). The migration script is run once - no build on the fly. It does a readdir() to get the full filenames and make sure that list entries are only for existing files. As a result, there is almost complete freedom in the output format for the dovecot-uidlist. Many thanks in advance! ---Jack P.S. For better or worse, it does seem that once you are stuck with whatever initial version you choose. -- Jack Stewart IMSS, California Institute of Technology, M/C 1-10, 1200 E.

[Dovecot] PAM session closes too soon
by Lauri Alanko 16 Aug '08

16 Aug '08

Hi. I'm trying to keep most of my data encrypted when possible, only keeping the decryption key in memory (and thus vulnerable to local attacks) when I'm actually using my data. In practice, this means using pam_mount to mount my home directory from an encrypted device. It almost looked like I could get this to work with mail as well, even when read via IMAP from a remote client: I placed my mail in the encrypted home directory, added pam_mount to /etc/pam.d/dovecot, and set session=yes in Dovecot's PAM configuration. Except that it didn't, quite: pam_mount worked just fine and mounted the encrypted disk using the IMAP password... and then immediately unmounted it, since for some reason session=yes means that Dovecot closes the session _immediately_ after opening it. This seems just silly. If a PAM session is to be used, then it seems obvious to me that its length should be exactly the length of the IMAP session. I can't see any reason for the current behavior, except maybe that it was a bit simpler to code and is sufficient for pam_mkhomedir (and only that). Can this be fixed with reasonable effort? Also, for pam_mount to work correctly, there must not be any file descriptors open in the mounted file system when the session closes, as otherwise unmounting is impossible. Will dovecot release all fds into the mail and index files when the session ends, or can it be made to do so? (UTSL is an acceptable answer.) Thanks in advance. Lauri Alanko la(a)iki.fi

[Dovecot] Problem with squirrelmail and dovecot 1.1
by Gerhard Wiesinger 16 Aug '08

16 Aug '08

Hello! I'm running squirrelmail 1.4.8 (I know this is not the latest version) and know I'm having troubles with: 1.) Folder list view 2.) Save to sent or Drafts folder. Configuration worked well. I think it has to do with the upgrade from dovecot 1.0 to 1.1 and the LIST command. Thunderbird/alpine work well. Commands from rawlog are: A002 LIST "" "~/Mail/Drafts" A002 OK List completed. or A002 LIST "" "~/Mail/sent" A003 CREATE "~/Mail/sent" A002 OK List completed. A003 NO Mailbox exists. Has something changed in the folder behaviour of dovecot from 1.0 to 1.1? If you need more information please let me know it. Any ideas? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/

If you learned and then nuked some headers for example, the file size would change and that would be an issue if you storage that in the filename (they wouldn't match) as well as the dovecot index for imap/pop would be off potentially. Possibly some active imap sessions might be confused as well. This patch only really is sensitive to the Maildir structure, it has been able to handle the mail directories. -- Gabriel Millerd

[Dovecot] Search for (any of) multiple terms slow
by Patrick Nagel 15 Aug '08

15 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, this may be an obvious logical problem I'm not aware of, which cannot be solved any more efficiently... but maybe it's just a bug or there is potential for optimisation in Dovecot (or Thunderbird?). When searching for multiple terms at once ("any of") with Thunderbird/Dovecot (using FTS Squat indexes), it takes much longer (not double the time, or a bit more than that, but really much, much longer) than when I search for only one term. Here are some figures (the IMAP commands are shown as issued by Thunderbird and recorded by Dovecot rawlog). While searching, I can see the 'imap' process using 100% CPU time. Searching for "xyz" in Archive and subfolders 4 secs 32 select "Archive" 33 uid SEARCH UNDELETED BODY "xyz" 34 select "Archive.2004" 35 UID fetch 1:* (FLAGS) 36 uid SEARCH UNDELETED BODY "xyz" 37 select "Archive.2004.2005" 38 UID fetch 1:* (FLAGS) 39 uid SEARCH UNDELETED BODY "xyz" 40 select "Archive.2004.2005.2006" 41 UID fetch 1:* (FLAGS) 42 uid SEARCH UNDELETED BODY "xyz" 43 select "Archive.2004.2005.2006.2007" 44 UID fetch 1:* (FLAGS) 45 uid SEARCH UNDELETED BODY "xyz" 46 select "Archive.2004.2005.2006.2007.2008" 47 UID fetch 1:* (FLAGS) 48 uid SEARCH UNDELETED BODY "xyz" 49 IDLE Searching for "xyz" and "abc" (any of) in Archive and subfolders 123 secs 50 select "Archive" 51 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 52 select "Archive.2004" 53 UID fetch 1:* (FLAGS) 54 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 55 select "Archive.2004.2005" 56 UID fetch 1:* (FLAGS) 57 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 58 select "Archive.2004.2005.2006" 59 UID fetch 1:* (FLAGS) 60 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 61 select "Archive.2004.2005.2006.2007" 62 UID fetch 1:* (FLAGS) 63 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 64 select "Archive.2004.2005.2006.2007.2008" 65 UID fetch 1:* (FLAGS) 66 uid SEARCH UNDELETED (OR BODY "xyz" BODY "abc") 67 IDLE Searching for "xyz", "abc" and "def" in Archive and subfolders 173 secs 68 select "Archive" 69 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 70 select "Archive.2004" 71 UID fetch 1:* (FLAGS) 72 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 73 select "Archive.2004.2005" 74 UID fetch 1:* (FLAGS) 75 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 76 select "Archive.2004.2005.2006" 77 UID fetch 1:* (FLAGS) 78 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 79 select "INBOX" 80 UID fetch 1:* (FLAGS) 81 check 82 select "Archive.2004.2005.2006.2007" 83 UID fetch 1:* (FLAGS) 84 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 85 select "Archive.2004.2005.2006.2007.2008" 86 UID fetch 1:* (FLAGS) 87 uid SEARCH UNDELETED (OR (OR BODY "xyz" BODY "abc") BODY "def") 88 IDLE Searching for "xyz", "abc", "def" and "ghi" in Archive and subfolders 217 secs 89 select "Archive" 90 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 91 select "Archive.2004" 92 UID fetch 1:* (FLAGS) 93 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 94 select "Archive.2004.2005" 95 UID fetch 1:* (FLAGS) 96 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 97 select "Archive.2004.2005.2006" 98 UID fetch 1:* (FLAGS) 99 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 100 select "Archive.2004.2005.2006.2007" 101 UID fetch 1:* (FLAGS) 102 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 103 select "Archive.2004.2005.2006.2007.2008" 104 UID fetch 1:* (FLAGS) 105 uid SEARCH UNDELETED (OR (OR (OR BODY "xyz" BODY "abc") BODY "def") BODY "ghi") 106 IDLE Patrick. - -- STAR Software (Shanghai) Co., Ltd. http://www.star-group.net/ Phone: +86 (21) 3462 7688 x 826 Fax: +86 (21) 3462 7779 PGP key: https://stshacom1.star-china.net/keys/patrick_nagel.asc Fingerprint: E09A D65E 855F B334 E5C3 5386 EF23 20FC E883 A005 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFIooxq7yMg/OiDoAURAhb9AJ4jOaK+eHXcSwJTAER8xEKIlJJt0gCgtZan wJm05V0F03gj+6YxbNOtCew= =jID/ -----END PGP SIGNATURE-----

[Dovecot] Migrating mbox to maildir
by Mike Hobbs 15 Aug '08

15 Aug '08

Sorry to bother everyone but I was wondering if it is possible for Dovecot to handle mbox AND maildir at the same time? Example: I want to convert from UW Imap using mbox to Dovecot using maildir. Do I need to convert ALL my users mbox mailboxes to maildir right away or can I convert them one at a time? I'd like to use maildir with all my new users, but I'd like to be able to continue using mbox for my old users and slowly convert them as I get time. Is this possible? I know Dovecot supports both formats, I just couldn't find anything in the install notes about using both at the same time. Thank you, mike

[Dovecot] Webmail app ... again.
by Roderick A. Anderson 15 Aug '08

15 Aug '08

There was a thread several weeks (or months) ago on webmail applications. I didn't like any of the options and only found few that I did but they were either expensive or not maintained. So ... I raised the question on the Catalyst Framework list about Perl based webmail apps and got nothing usable. It came down to what would it take to build a Perl (Cat) webmail app. Several others on the list got interested so we decided to build it. The main issue I run into is my lack of understanding of the ins-and-outs of the IMAP specification and the features that come with using Dovecot. (Oh yeah. Dovecot was the preferred IMAP server!) Another project I'm working on uses IMAP and what I found was there is a great quantity of Perl modules for dealing with IMAP. A great quantity! Unfortunately many of them assume a deeper knowledge of IMAP than I have so are very confusing. What I'm looking for is a good reference, besides the RFC, on IMAP. Anything out there? Electronic or dead-tree is fine. (A book of Dovecot would be neat too.) TIA, Rod --

[Dovecot] restricting shared folders access
by Andrew Von Cid 14 Aug '08

14 Aug '08

Hi all, I have a dovecot setup with virtual users and a passwd-file passdb. All users have the same uid and gid. Recently I got my public folders working using namespaces and they work great. However, now I'm trying to share a folder between a limited number of users and so far I failed to get it working. Symlinks aren't an option because users need to be able to create subfolders of the shared folder so I'm trying to do it with namespaces but I'm not sure how to restrict access to a limited number of users. I tried doing it with groups. I made sure that the shared folder's group is set to 'staff' and the mode is 070, I also changed the group of a few virtual users to 'staff'. However, when I try accessing the shared folder I get a permission denied error (although the user is in the staff group). Can someone please recommend the best way to do this? Should I look into ACL's? Many thanks, Andrew.

[Dovecot] Plugin when downloading mail
by martijn＠youngguns.nl 14 Aug '08

14 Aug '08

Is there a way to modify mail messages when they are downloaded using a special login. eg. my normal login for dovecot is martijn(a)youngguns.nl but when I log in using martijn(a)dosomething.youngguns.nl I would like to download my mail which are processed using a Perl script. The Perl script will modify the content of the message (the message body). So I don't want to change the header or IMAP flags. Martijn

[Dovecot] Has anyone ever seen outlook do single sign on with dovecot/etc?
by Jason Gunthorpe 14 Aug '08

14 Aug '08

Hey all, I'm curious, has anyone been able to get outlook to do single sign on with a linux IMAP/SMTP back end? I have it doing NTLM authentication via the dovecot winbind module with Samba 3.2 just fine, but I have yet to see it try to use the cached windows logon credentials.. It appears to do an NTLM exchange with a blank password and then prompt for a password and then do an exchange with the given password. It does the same thing if PLAIN authentication is used. I'm starting to suspect MS deliberately hobbled outlook so that it uses the SSPI to exchange an entered password but not ever the logon credentials.. Does anyone know different? What a topsy-turvy world when thunderbird using SSPI works better on Windows than outlook. :| Thanks, Jason

[Dovecot] Disabling access for one user
by Kenneth Porter 14 Aug '08

I'm converting my system from mbox to Maildir one user at a time, and I'd like to disable access for the user I'm working on. Is there a way to tell Dovecot to lock out a specific user? Perhaps with a control file in the home directory? At the same time, how can I get sendmail+procmail to tempfail incoming messages for one user until I'm done?

Heh, I see ;) As it is, the FTS plugin is quite useless to us though :( most of the time people are doing a (real world) search, they don't remember the exact word they're looking for. For example they only remember that the mail they're looking for contained "English" and "automobile" - or was it "Englisch" and "Automobil", because the mail was in German? So to get a list of all possible mails, they want to make use of the OR connection of search terms... > Requires a lot > more complexity to the code though.. Couldn't Dovecot just search the index with each single word (as it does now without OR), and then merge the results, filtering out double UIDs? This is probably not the most efficient way to solve this, but it would be definitely *much* faster than not using the indexes at all - and doesn't sound too complex to me. Are there any other not-yet-implemented SEARCH features that don't work with the FTS plugin?

[Dovecot] mbox empty messages in Sent folder
by Diego Liziero 14 Aug '08

14 Aug '08

I'm talking about mbox Sent folder, where some mailers append through imap server a copy of each message they send. Sometimes, just three header lines got appended instead of the whole mail message, such as: >From xxxxxxxx(a)xxxxxx.xxxxxx.xxxxx.xx.xx Fri May 23 12:30:14 2008 X-UID: 2852 Status: RO This happened in the past (dovecot-1.1-beta/rc with Evolution and with Thunderbird), and happened last week with dovecot-1.1-rc5 (+ last week hg patches). Anyone had a similar issue? Regards, Diego.

[Dovecot] 1.1.x problems
by Andre Hübner 13 Aug '08

13 Aug '08

Hi, since upgrading to 1.1.x i still have this bugs "Next message unexpectedly lost " I read this Maillist some months ago and i believe that im not the only one... The Panics and crashes in 1.1.1 are gone by upgrading to 1.1.2 but these "Next message unexpectedly lost " bugs are really annoying if users can't download complete mails. is there something new to this issue. all recommend changes did not help. The only thing i could do is downgrade to 1.0.15 and all works fine. i can not keep the 1.1.x versions in my repo untill this case is solved. :( Thanks Andre

[Dovecot] [PATCH] Support GSS-SPNEGO natively
by Jason Gunthorpe 13 Aug '08

13 Aug '08

I cooked this up while trying to figure out why thunderbird on Windows w/ SSPI was not working, but it turned out thunderbird does not use it, so I haven't been able to test it yet. I'm presenting it for discussion only, unless someone else can try it :) Modern versions of MIT kerberos support GSS-SPNEGO natively, but are only willing to negotiate for kerberos tickets and not NTLM messages. This is how the SPNEGO works in libapache-mod-auth-kerb-5.3 which simply passes SPNEGO packets directly to gssapi if the library is new enough. There is even a configure feature test for the gssapi library in that packages configure script. Note that Debian etch's standard kerb libaries (1.4) are not good enough for this. Having this work means the other gssapi policy knobs in dovecot, like auth_gssapi_hostname, work properly. Instead of 'whatever it is that samba does'. I guess it fixes the concerns about winbind accesses blocking (although don't the gssapi calls block??) In light of this it is really only useful to use winbind if you want to support NTLM as kerberos will do the necessary exchanges with the kdc for an Active Directory domain. In truth a proper and complete design would somehow layer the built in NTLM module under the SPNEGO negotiation and only pass NTLM messages off to samba but I doubt anyone cares with NTLM being rather obsolete. --- dovecot-1.0.13/src/auth/mech-gssapi.c 2007-12-11 11:52:08.000000000 -0700 +++ dovecot-1.0.13-jgg/src/auth/mech-gssapi.c 2008-08-11 23:52:15.000000000 -0600 @@ -417,4 +424,21 @@ mech_gssapi_auth_free }; +/* MTI Kerberos > 1.5 supports SPNEGO for Kerberos tickets internally. + Nothing else needs to be done here.

[Dovecot] [PATCH] Allow GSSAPI to work with multihomed hosts
by Jason Gunthorpe 13 Aug '08

13 Aug '08

I saw some past chatter on this in the list archives, but here is another stab and another rational. This patch follows a similar patch to openssh in that it allows any key in the specified keytab to match the incoming host key. This is necessary for multihomed hosts. See: https://bugzilla.mindrot.org/show_bug.cgi?id=928 IMAP/POP seem to be a strong candidate to be multihomed because they are very likely to have an internal to a firewall and external to a firewall name. Due to the way MIT kerberos handles host name resolution via reverse IP lookup this can often result in multiple principle names and there is simply nothing to be done about it. This is my situation.. When you add windows into the mix, which uses a totally different set of rules to determine the principle all hope seems to be lost to have a single service principle name for an imap server :( I was able to make things work for my environment using only the auth_gssapi_hostname feature if only MIT kerberos was used, but as soon as windows SSPI was involved it choose a different hostname. Thus we want to have GSSAPI to match any service principle in the keytab. As far as security concerns go, the admin can configure the keytab for dovecot to be seperate from the system key tab and contain only valid imap SPNs, but in truth it probably doesn't matter. I choose to just use the magic configurable: auth_gssapi_hostname = $ALL rather than introduce more configurables FWIW, after applying this I now am happy to say I have an Active Directory KDC, with dovecot providing gssapi auth to thunderbird on both linux (mit kerb 1.6) and windows (sspi).. --- dovecot-1.0.13/src/auth/mech-gssapi.c 2007-12-11 11:52:08.000000000 -0700 +++ dovecot-1.0.13-jgg/src/auth/mech-gssapi.c 2008-08-11 23:52:15.000000000 -0600 @@ -101,6 +101,13 @@ gss_name_t gss_principal; const char *service_name; + if (strcmp(request->auth->gssapi_hostname,"$ALL") == 0) { + auth_request_log_info(request, "gssapi", + "Using all keytab entires"); + *ret = GSS_C_NO_CREDENTIAL; + return GSS_S_COMPLETE; + } + if (strcasecmp(request->service, "POP3") == 0) { /* The standard POP3 service name with GSSAPI is called just "pop". */

[Dovecot] dovecot sieve sends vacation messages with null envelope sender
by Josef Liška 13 Aug '08

13 Aug '08

I am using this simple sieve script to do "vacation": require ["fileinto", "vacation"]; if exists "X-Spam-Flag" { stop; } vacation :days 1 :subject "Out of office reply" :addresses ["<email address hidden>", "<email address hidden>" ] "I am on vacation until 2008-08-07. If you have something urgent, please contact: Jan Novak <email address hidden> "; I use sql lookups for users and passwords. For some reason the default location ~/.dovecot-sieve did not work for some reason. However I prefer to put sieve scripts to /var/lib/sieve and when I added additional field to lookup with this location it started to work. But it sends vacation messages with null envelope sender, which is in my opinion undesirable, because many vacation messages are caught in spam filters. I think there could be same sender on envelope. In dovecot-sieve/src/sieve-cmu.c around line 380 is a call to smtp_client_open(src->addr, NULL, &f); NULL could be replaced with src->fromaddr Maybe some more patching may be necesary. I found similar patch for cyrus-imapd at http://oss.digirati.com.br/mail/cyrus.html <http://oss.digirati.com.br/mail/cyrus.html> My current system: 1) Ubuntu 8.04.1 jl@mail:~$ dovecot --version 1.0.15 It is a backported package from ubuntu intrepid ibex. However the same applies for dovecot 1.0.10 which is in ubuntu 8.04. Summary: I expect messages sent by vacation recipe should have envelope from same as user's e-mail address. This is then writen to Return-Path: header by receiving MTA NULL envelope from is used, resulting (in my case) to Return-Path: <> rewriten by postfix to Return-Path: <MAILER-DAEMON> by receiving MTA

[Dovecot] RfE: use HOSTNAME environment variable in hostpid_init()
by Heiko Schlichting 13 Aug '08

13 Aug '08

Hi, All parts of dovecot except deliver uses the result of hostpid_init() in src/lib/hostpid.c as a hostname which only asks gethostname(). deliver honours environment variable HOSTNAME in src/deliver/deliver.c: getenv("HOSTNAME"); and uses the hostname of hostpid_init() as a fallback. Wouldn't it be consequent to evaluate the environment variable HOSTNAME in hostpid_init() with fallback to gethostname() and remove the special behavior from deliver? The dovecot master process should export $HOSTNAME to all childs in this case. Motivation: Dovecot uses the hostname as part of Maildir file names and gethostname() is not fully qualified on all operating systems (it is on IRIX but not on Linux). But unqualified hostnames are not unique and it is frequent that dovecot hosts are named "mail" oder "imap" as hostname. To distinguish between mail.domain1.com and mail.domain2.net would be easier if dovecot evaluate $HOSTNAME in all case not just deliver as program imap can create Maildir files as well.

[Dovecot] syslog with PID
by Heiko Schlichting 13 Aug '08

13 Aug '08

Hi, LOG_NDELAY is the only option for openlog() in dovecot 1.1.2. Wouldn't be LOG_NDELAY|LOG_PID as option parameter much more useful? Without logging the pid, it is impossible to match 'Disconnected' log entries and the corresponding session start/login. Therefore I suggest to use LOG_NDELAY|LOG_PID in the options of i_set_failure_syslog() at all 6 occurrences which passes it to openlog(). I know that it is possible to - use logging to file - patch it myself but I can't see good reasons in not using LOG_PID here. As far as I know, most other programs specify LOG_PID. Without LOG_PID: Jul 31 10:21:08 name dovecot: IMAP(hsg): Disconnected: Logged out bytes=28/242 With LOG_PID: Jul 31 10:21:08 name dovecot[17016]: IMAP(hsg): Disconnected: Logged out bytes=28/242 Heiko Heiko Schlichting Freie Universität Berlin heiko(a)FU-Berlin.DE Zentraleinrichtung für Datenverarbeitung (ZEDAT) Telefon +49 30 838-54327 Fabeckstraße 32 Telefax +49 30 838454327 14195 Berlin

[Dovecot] IMAP inbox: cannot delete tagged messages or change their tag
by Epimedia 13 Aug '08

13 Aug '08

Hello, a bit of a problem with Dovecot. Version is 1.0.15 and is a default install (no changes to config) from FC8 repository... except that Dovecot is configured to use Maildir I have a user on the system who uses the tags in Thunderbird (Important, Personal etc). When she tags the messages they cannot be deleted and their tags cannot be changed. When deleting a message from the IMAP inbox it momentarily disappears and moves a copy to the Trash but when the IMAP inbox is reloaded the message reappears. The same happens when I try to change a tag: it comes back with the previous tag. Untagged messages can be freely deleted. Also, this problem does not happen if the messages are in a IMAP folder. They can be freely deleted. The problem seems specific to Dovecot, not Thunderbird, as I am able to tag and delete messages in another IMAP account. Also, accessing the same IMAP account using OS X Mail the messages come back after deleting them. Where should I start looking for a solution to this problem?

[Dovecot] Trying to Hide Namespace - new configuration options?
by Daniel Watts 13 Aug '08

13 Aug '08

Using 1.1.2 We have: # default namespace namespace private { separator = / prefix = inbox = yes #location = maildir:/home/virtual/%h #Maildir } # for backwards compatibility: namespace private { separator = / prefix = mail/ location = maildir:%h/Maildir/ #Maildir hidden = yes list = no } The 'hidden=yes' seemed to do nothing but saw earlier in this list a reply to add 'list=no'. This has worked to hide all folder but we still have /mail/Trash showing and it refuses to go away even after unsubscribing. mail/Trash appears when I set my email client to use folder prefix "mail/". If i set the prefix to blank I only see my Inbox and Deleted folders. Interestingly it shows 'Deleted' not 'Trash'. I guess Thunderbird renames 'Trash'. What other configs are there to try? Is there a list of config changes for 1.1.x anywhere? We were not aware of the list=no config. Thanks, Daniel

[Dovecot] Dovecot,nfs or memory indexing
by Sebastian Tymków 13 Aug '08

13 Aug '08

Hi, I wonder if it's normal behaviour that indexes created in memory have long creation time. Other problem is that indexes created on nfs sometimes get crushed and I need to delete indexes in case of fetching mails ( I see mails on hd but when telnet on host and make stat I don't see any). Does version 1.1.x correct this errors ? And what is better to use : nfs or memory indexing ? Can someone point me adventages and disadventages of using both solutions? Best regards, Sebastian

[Dovecot] Quota does not apply.

13 Aug '08

Hello list: I am try to run quota plugin but only works a part. The users are virtual and his homedir and mbox are in NFS server, INDEX files are in local disk. Quota only is applied to global home, if I configure a low global quota and sent an mail to my e-mail, quota works fine, mail is temporally deferred. But, if I configure a high global quota and a small quota for INBOX, sent a mail that is more big that quota for INBOX, then quota is not applied and the mail is delivered to INBOX.

[Dovecot] Server-side sieve for client-side copies
by Daniel L. Miller 13 Aug '08

13 Aug '08

I know I could test this - but I'd rather ask first. To my knowledge, we haven't come up with a good server-side implementation for savings copies of sent messages (by all means correct my ignorance in this regard). So the typical way is to enable it in clients like Thunderbird (this prompted a whole discussion of how to save these messages without sending them to the server multiple times). My understanding is that sending a message from a client (use Thunderbird for simplicity of this conversation) is performed via SMTP. Saving a copy into a sent folder is performed via IMAP (hence the multiple transfers to the server). Now that I've laid a background - let's make it Dovecot specific. I don't know how "behind-the-scenes" Dovecot performs the act of saving mail messages that it receives from IMAP, instead of SMTP. Specifically, if I'm using sieve filters via deliver - can I setup a filter that will place mail copies to specific recipients into specific subfolders? -- Daniel

[Dovecot] stopping dovecot
by Arkadiusz Miskiewicz 12 Aug '08

This may be a silly question but how to correctly stop dovecot and be sure that it's possible to start it again? kill -TERM `cat /var/run/dovecot/master.pid` doesn't work well. I have imap-login processes staying arround and occupying port which leads to Fatal: listen(0.0.0.0, 993) failed: Address already in use when trying to start again 2s after stopping. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Hi I'm using dovecot imap with ldap accounts. User management interface is phamm. Internal clients connect directly using imap client. External clients must use webmail (squirrelmail). But not everyone is supposed to use webmail. Is there any way to control who is allowed to log in from a specific IP (webmail ip)? Thanx for suggestions Jan

[Dovecot] Mail quota usage errors
by Jeff Koch 12 Aug '08

12 Aug '08

Hi: We're using dovecot with qmail and vpopmail and are having problems with major inaccuracies in the mail quota usage maintained in the maildirsize file. Although the file starts off accurate after we delete it and force a rebuild it quickly becomes inaccurate. It doesn't seem to be catching new mail added to the directories. Does anyone have any suggestions or links to pages that will help us troubleshoot/correct this problem. Best Regards, Jeff Koch

[Dovecot] SSL Certifcates

Hi anyone. Can dovecot be configured to authenticate user using only SSL Certificates only and not ask for a password. So far I've got it taking the username from the common name of the certificate but I like it to use the certificate in place of the password. Is this possible and how? -- Regards Stephen.

[Dovecot] Possible bug in v1.1.1
by John Wood 12 Aug '08

12 Aug '08

Greetings, I recently upgraded our server from Dovecot 1.0.14 to 1.1.1. I am building using the FreeBSD ports system, so nothing is custom aside from the flags set there. dovecot fell down a few days after the update with: pid 1823 (imap), uid 1000: exited on signal 11 the mail log shows: Jul 4 14:36:07 hostname dovecot: IMAP(username): Corrupted index cache file /home/username/mail/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 10462 Jul 4 14:36:07 hostname dovecot: child 1823 (imap) killed with signal 11 unfortunately I do not have a core.

[Dovecot] Auth message
by Pavel Shirov 12 Aug '08

12 Aug '08

Recently my network was scanned. Various services was scanned, and checking the logs of mail server the following string draw my attention: mail dovecot: pop3-login: Disconnected: user=<ttejmgpfip>, method=PLAIN, rip=87.228.15.180, lip=x.x.x.x This looks weird to me, because pop3-login: Disconnected looks like succesful login attempt to me. I have no such user named ttejmgpfip exits ofc. I've check what dovecot writes to log if try PLAIN login method with random login/password, and it's "Aborted login". As I'm using SQL backend for user/pass database, I'm afraid that I might have something misconfigured and a possible sql-injection or something else allowed attacker to "login" with random password. Or my worries are groundless and I can get such message in some case of unsuccessful login? Running dovecot 1.0.rc15 (CentOS 5). Here is how my sql auth done: default_pass_scheme = MD5 password_query = SELECT password FROM mailbox WHERE active = '1' AND (LEFT(username, INSTR(username, '@')-1) = '%u' OR username = '%u') user_query = SELECT maildir as home, 6000 AS uid, 6000 AS gid, domain FROM mailbox WHERE LEFT(username, INSTR(username, '@')-1) = '%u' OR username = '%u' I have such query so it is possible for a user to login either as user@domain or just as user (I have single domain).

[Dovecot] About domains in antispam plugin

Hi there, I have the problem that the antispam filter is looking in a different subdirectory (I think is the domain subfolder) than the actuallly used i.e., The following error message is constant: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Aug 12 12:07:58 mail dspam[4540]: Unable to open file for reading: /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c24 9461173910573.sig: No such file or directory Aug 12 12:07:58 mail dspam[4541]: Unable to open file for reading: /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c24 9461173910573.sig: No such file or directory ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The file in the error exists but in a different subdirectory than the one AntiSpam Plugin is looking: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ls -l /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c249461173910573.sig ls: cannot access /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c249461173910573.sig: No such file or directory ls -l /var/spool/dspam/data/mydomain.com/itadmin/itadmin.sig/48a1c36c249461173910573.sig -rw-rw---- 1 root dspam 968 Aug 12 12:07 /var/spool/dspam/data/mydomain.com/itadmin/itadmin.sig/48a1c36c249461173910573.sig ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I looked at the /etc/dovecot/dovecot.conf for a line containing a local doman vs mydomain.com but there's nothing even in the comments.

[Dovecot] NFS vs CIFS - and Dovecot
by Daniel L. Miller 12 Aug '08

12 Aug '08

I've seen a number of posts discussing NFS based storage and issues with Dovecot. When the term "NFS" is used - does this exclusively refer to the Linux NFS network file system, or is it a generic reference to any network file system? I don't recall seeing any posts referencing issues with CIFS or SMBFS - is this because no one is using it, or because it just works instead of fiddling with NFS? -- Daniel

[Dovecot] Install from source of dovecot 1.1.2
by Guy 12 Aug '08

12 Aug '08

Hi guys, I have what I'm sure is a stupid question. I'm trying to install Dovecot 1.1.2 from source and my command sequence is this: cd dovecot-1.1.2 ./configure --prefix=/usr --exec-prefix=/usr --with-mysql --with-storagesmaildir --sysconfdir=/etc/dovecot make make install cd ../dovecot-sieve-1.1.5 ./configure --with-dovecot=../dovecot-1.1.2 make make install I don't get any errors during either install I've done the odd config on dovecot to try and keep it as close to the install dirs used by the Dovecot package included with Ubuntu. Once it's done, dovecot -n still looks in /usr/local/etc and when I try and start dovecot it looks for the libexec dir in /usr/local instead of /usr. Is there something I'm missing on the configure? I've very, very little experience (rather obviously) installing directly from source so any advice would be greatly appreciated. Thanks Guy -- Don't just do something...sit there!

[Dovecot] Cyrus vs Dovecot
by Mathieu Kretchner 12 Aug '08

12 Aug '08

First of all : forgive me for my poor English Hello all, I've to compare cyrus with dovecot for my work. Because these are the only solutions that could fit our needs. Unfortunately I really don't know a lot about dovecot and I would like to have some of its assets. Here are the properties of the versus table I've done : dovecot cyrus Installation: Update: Migration from cyrus : Migration from dovecot : functionalities : Management : Local Delivery : availability : Security : Indexes management : NFS compatibility : Scalability : Configuration : interoperability : Sieve filter : Documentation : Quota capability : Performance : IMAP capability : So I know this can scared you, but If you have some asset for dovecot, It could be great and a lot more FAIR !! Thank you in advance for your advice.

[Dovecot] GlusterFS
by Jeroen Koekkoek 12 Aug '08

12 Aug '08

Hi everybody, We use a Dovecot setup with GlusterFS. Dovecot 1.1.2 and GlusterFS 1.3.9. I enabled the following options (I don't have posix-locks translators): lock_method = dotlock dotlock_use_excl = no mmap_disable = yes mail_nfs_index = yes mail_nfs_storage = yes I receive the following error message. Aug 7 09:38:51 mta2 dovecot: POP3(somebody(a)domain.tld): nfs_flush_fcntl: fcntl(/var/vmail/domain.tld/somebody/Maildir/dovecot.index, F_RDLCK) failed: Function not implemented I think that I can disable mail_nfs_index to fix these messages. Has anybody had the same problem, if so, how did you solve it? Kind regards, Jeroen Koekkoek

[Dovecot] proxy_maybe and IPv6
by Matthieu Herrb 12 Aug '08

12 Aug '08

Hi, Using dovecot 1.1.2 on a dual-stack server, with the 'proxy_maybe' attribute to forward some clients to another server, it seems that only clients connecting with the same protocol version as the one used by address in the 'host' attribute in the password db are recognized as local. If an IPv4 address is specified as 'host', a dovecot proxy is created for clients connecting using IPv6 to this server, and symmetrically if the proxy is specified as an IPv6 address, clients connecting through IPv4 will get forwarded to the v6 address. Is there a way to avoid that? -- Matthieu Herrb

[Dovecot] optionnal arguments to ntlm_auth helper
by François LEGAL 10 Aug '08

10 Aug '08

Hello, I'm setting up (at least I try) to set up network services with single sign on. I could build and configure dovecat to use samba's ntlm_auth helper to achieve ntlm authentication of imap users. The point is, I wanted to restrict which users could actually authenticate through ntlm. The ntlm_auth helper has this ability with the --require-membership-of=... command line parameter. I first tried (unsuccessfully) to add this parameter to the auth_winbind_helper_path token in dovecot.conf, and figured out by checking the source that this was not possible. I then decided to patch the source so that one can pass any argument to the ntlm_auth helper by specifying at new line in dovecot.conf with the token "auth_winbind_helper_args" (for instance, what I wanted to do is "auth_winbind_helper_args = --require-membership-of=... ") Well, here comes the patch. It is to be used with recent 1.1.2 release. Best regards François

[Dovecot] tcp-wrappers.patch
by Edgar Fuß 09 Aug '08

09 Aug '08

I'd like to see tcp-wrappers.patch getting integrated into dovecot. I ported the original 1.0 patch to 1.1, but would prefer not to have to maintain another local patch. As the name suggests, the patch adds libwrap support to dovecot. We use is to limit access from outside our network to secure (imaps/pop3s) protocols only and to exclude certain internal addresses from accessing dovecot in general. I fully understand Timo's concern of people not reading documentation and then whining that librwapping doesn't work whereas they simply forgot to put hosts.{allow,deny} into the login chroot. Would it be acceptable if either dovecot itself or the init script copies /etc/hosts.{allow,deny} into the chroot (unless it's already there)? Also, dovecot could probably complain/abort/turn off libwrap if these files are missing in the login chroot. The problem mainly occurs with the default (Linux) setting of login_dir = /var/run/dovecot/login; on NetBSD, I use /var/chroot/dovecot-login instead, which doesn't get wiped out at boot. Comments? Suggestions? Oh, yes, managesieve (which uses src/login-common) would need a slight update, too.

[Dovecot] Dovecot 1.1.1 killed with SIGABRT
by Andreas M. Kirchwitz 08 Aug '08

Hi folks, with Dovecot 1.1.1, I've had two "crashes" (SIGABRT) recently. Dovecot 1.1.1 has been compiled from source and is running on Fedora 8 Linux 32 Bit (all patches) with custom OpenSSL 0.9.8h.

He used IMAP to access his INBOX, but he forgot to configure this for all other folders as well. Now, Pine modified /home/user1/Mail/Trash directly, and when Dovecot stumbled upon this file it killed itself with signal 6. The problem is not reproducible. After this single failure, Dovecot doesn't seem to have any problems with the folder. However, instead of this panic operation, Dovecot maybe could issue a warning or error response to the client so that the user (hopefully) gets a clue about what's going wrong. Second, the "big" problem with Thunderbird 2.0.0.14: Jul 12 01:04:06 linux dovecot: imap-login: Login: user=<user2>, method=CRAM-MD5, rip=138.201.2.4, lip=138.201.2.2, TLS Jul 12 01:04:45 linux dovecot: Panic: IMAP(user2): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Jul 12 01:04:45 linux dovecot: IMAP(user2): Raw backtrace: imap [0x80cf2f0] -> imap [0x80cf34a] -> imap [0x80cec5c] -> imap [0x809ccba] -> imap [0x8080d10] -> imap(mbox_sync+0x522) [0x80817d2] -> imap [0x807a334] -> imap(index_transaction_commit+0x4e) [0x809d99e] -> imap(cmd_copy+0x35f) [0x805b37f] -> imap(cmd_uid+0x59) [0x805f489] -> imap [0x805fe2c] -> imap [0x805fed5] -> imap [0x8060695] -> imap(client_input+0x5e) [0x80608ae] -> imap(io_loop_handler_run+0x100) [0x80d6c30] -> imap(io_loop_run+0x28) [0x80d5dc8] -> imap(main+0x4a1) [0x80683d1] -> /lib/libc.so.6(__libc_start_main+0xe0) [0x149390] -> imap [0x805a211] Jul 12 01:04:45 linux dovecot: child 25672 (imap) killed with signal 6 [happens over and over in an endless loop until Thunderbird is killed] This has been a nasty one. Different user, different mail client. INBOX with 350 messages in total, 3 of them new. Started Thunderbird, index page is displayed fine, then clicked on one of the 3 new messages to read it. For no apparent reason, Dovecot dies with signal 6. Thunderbird reconnected automatically, and then Dovecot dies again. Nice endless loop ... Stopping and restarting the complete Dovecot subsystem with the help of the init.d script didn't help. Finally the crashes stopped after removing the cache files in /home/fubar/Mail/.imap/INBOX. It's obvious that the cache files got corrupted somehow. There was plenty of disk space free. And the cache files have been freshly created from scratch with Dovecot 1.1.0. Other folders were not affected. Except Dovecot, nobody ever touches these cache files. Well, the good news is, it stopped crashing after removing the cache files. The bad news is, without the cache files (which I removed) the problem cannot be reproduced. So, there's nothing more to offer than these two backtraces. Both crashes are not related to each other and happened to different users with different clients. Maybe the backtraces and my descriptions help to find what's going wrong or how to make Dovecot behave more robustly. If there's any additional information needed, please let me know. Sorry that I didn't save the corrupted cache files. Greetings, Andreas

[Dovecot] Expire Plugin - LDA with Vpopmail errors

[Dovecot] virtual domains and SSL certificates
by Kacper Wysocki 07 Aug '08

07 Aug '08

Hi all, I have dovecot 1.1.0 setup to access vpopmail accounts for several virtual domains. Dovecot IMAP is accessed through several virtual domains as well, ie mail.foo.com an d mail.bar.com The problem is that the configuration file specifies only one certificate file for dovecot, which means only one Common Name, which means one cannot provide one server cert that will match mail.foo.com AND mail.bar.com, and either mary(a)foo.com or bob(a)bar.com will get a "Security Error: Domain Name Mismatch" in their mail client when connecting through IMAPS. How can I avoid this domain name mismatch error? Regards, Kacper Wysocki

Update: dovecot can't find the mail directory because of mail_location = maildir:/var/vpopmail/domains/%d/%n/Maildir and dovecot doesn't know anything about domain aliases. ln -s ~vpopmail/domains/maindomain ~vpopmail/domains/aliasdomain fixes the problem for dovecot. -K

The wiki page says that the uid and guid can be set in the config file, but doesn't give any indication of the lines to use. Maybe the information could be added?

[Dovecot] Dovecot 1.1 Quota Plugin Configuration?
by David Reid 07 Aug '08

07 Aug '08

With 1.0 I had the quota plugin set to allow some accounts to have no quota by setting their size (in bytes) to 0 (via mysql). Following the upgrade to 1.1 this no longer seems to work and has resulted in a lot of annoyed people having messages bumped :-( The config I have is as follows... quota = maildir quota_rule = *:storage=15M quota_rule2 = Trash:ignore quota_rule3 = INBOX.Trash:ignore quota_rule4 = INBOX.SpamTrain:ignore quota_rule5 = SpamTrain:ignore In the sql.conf I get the quota for each mailbox using this line user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, xxx AS uid, xxx AS gid, concat('maildir:storage=', mb_quota) AS quota FROM mailboxes WHERE mb_mbname = '%u' AND mb_active = '1' With this setup when I have a mb_quota set to 0 it simply bounces all messages for the mailboxes that should have no quota. Any ideas how I need to fix this? david

[Dovecot] Experience moving mailboxes from Dovecot 0.99.14 to Dovecot 1.07 => Improvement possible
by Benoît DESLOGES 07 Aug '08

07 Aug '08

Hi, This small mail to share my observation about a recent move of mailboxes between two servers and ask about explanation and/or improvement about UIDL in dovecot. SV1 : Dovecot 0.99.14 / Red Hat Fedore Core 4 SV2 : Dovecot 1.07 / CentOS 5.2 Mailboxes in /var/spool/mail on the twoo servers. Test will be done with outlook express with option "leave message on server" checked. Goal is simply to move users mailboxes from SV1 to SV2 without re-downloading all messages. Try 1: - Stop dovecot on SV2 - Clear all dovecot indexes on SV2 - Rsync of my mailbox - Start dovecot on SV2 - Update pop setting in outlook and send/receive Result : => starting to download 3000 mails... After some debug, I discovered that UIDL where not of the same format => put pop3_uidl_format = %v.%u in dovecot.conf of SV2. Try 2: Same operations as Try1 Result : => starting to download 3000 mails... UIDL's where of the same format but values where not corresponding... Teleting on SV1 and asking UIDL, last value is xxxxxxxxxx.85878. On SV2, xxxxxxxxxx.85879 was the FIRST value of the list. Conclusion for the moment, Dovecot has a problem with the detection of existing UID of the moved mailbox. Comparaison of first header found from the two mailboxes show ... differences ! SV1 give the following : (...) X-UID: 70570 Content-Length: 1561 X-IMAPbase: xxxxxxxxxx 85845 $MDNSent X-Keywords: (...) SV2 give the following (after first POP attempt) : (...) Content-Length: 1561 X-IMAPbase: xxxxxxxxxx 0000089204 $MDNSent X-Keywords: X-UID: 85846 (...) Observation : X-UID: 85846 is not at the same place in the header. Try 3: - Stop dovecot on SV2 - Clear all dovecot indexes on SV2 - Rsync of my mailbox - Edit mailbox and move X-UID header after the X-Keywords header - Start dovecot on SV2 - Update pop setting in outlook and send/receive Result : => OK. Is that normal that dovecot is impacted by the position of the headers ? Maybe some improvement possible ? Maybe theyre is another method to make my migration ? Any observation or comment is welcome... -- Benoît Desloges Network Engineer

[Dovecot] Fwd: Re: sasl parameters missing (in postfix)
by Daniel Black 07 Aug '08

07 Aug '08

In response to my request for postfix to support dovecot auth arguments I got the forwarded reply. If someone gets around to this before me I won't be offended. ------------ Story is I deployed a webmail with certificate based authentication that substitutes a global master password (http://wiki.dovecot.org/Authentication/MasterUsers) when the certificate matches. The webmail accesses the inbox by imap and reuses the password for smtp through postfix. I configured dovecot sasl authentication to allow a particular global password to be allowed from one IP address of the webmail server. Unfortuanately it seems as though postfix doesn't pass rip= (remote ip) or the other AUTH parameters of the protocol (http://dovecot.org/doc/auth-protocol.txt) Is adding these parameters to postfix's sasl authentication a useful feature request? ---------- Forwarded Message ---------- Subject: Re: sasl parameters missing Date: Thu, 7 Aug 2008 From: Wietse Venema <wietse(a)porcupine.org> To: Daniel Black <daniel.subs(a)internode.on.net> Daniel Black: > Thanks Wietse, > > On Tue, 5 Aug 2008 09:30:44 am Wietse Venema wrote: > > Postfix passes the information in the SMTP client's AUTH command. > > This is how I got the Dovecot extension from Timo.

I won't. > > On the basis of this apparent stability and compatibility would you consider > accepting a patch? Yes. No promise, though, that it will be adopted. One consideration is that Postfix does not talk directly to Dovecot, but instead talks to an abstraction layer that is used for both Cyrus SASL and for Dovecot. Obviously, that XSASL abstraction layer must not be made specific to the underlying Cyrus SASL or Dovecot implementation. The solution therefore is not to extend XSASL functions with one extra argument for each Dovecot feature. Apart from being Dovecot-specific, functions with many parameters are difficult to update correctly; compilers can't always tell that two arguments should be swapped. I solved the problem of many-parameter functions by using macros such as TLS_SERVER_START(). This gives more assurance that data is passed correctly, and it less likely to break due to human maintainer error.

[Dovecot] Purpose of files under .imap
by Kenneth Porter 07 Aug '08

07 Aug '08

I've got a user with an unusable account. Tbird just sits in a loop endlessly logging in over and over when a particular folder is selected. What files under .imap associated with that folder can be safely deleted? What's stored in all of them? I see all of these: .customflags dovecot.index dovecot.index.cache dovecot.index.log .imap.index .imap.index.data .imap.index.log .imap.index.tree

[Dovecot] Next message unexpectedly lost
by Kenneth Porter 07 Aug '08

07 Aug '08

Using 1.1.2. I'm getting the above message over and over in the error log. Dovecot drops the connection and the client (Tbird) just keeps retrying in an endless loop. Using Wireshark to sniff the exchange, it looks like the command that fails looks like this: 5 UID fetch 1:9749,9751:9763,9765:9930,9932,9934:9942 (UID RFC822.SIZE FLAGS BODY.PEEK[HEADER.FIELDS (From To Cc Subject Date Message-ID Priority X-Priority References Newsgroups In-Reply-To Content-Type)]) Dovecot seems to be shutting down after receiving this. Mulberry doesn't seem to have the problem, presumably because it's sending a different command sequence that doesn't stroke this. Here's the failing code, in i_stream_raw_mbox_read : if (stream->istream.v_offset - rstream->hdr_offset + new_pos > rstream->mail_size) { /* istream_raw_mbox_set_next_offset() used invalid cached next_offset? */ i_error("Next message unexpectedly lost from %"PRIuUOFF_T, rstream->hdr_offset + rstream->mail_size); rstream->eof = TRUE; rstream->corrupted = TRUE; return -1; } I've tried deleting the associated .imap/folder contents but it must regenerate the same bad data as it happens again.

[Dovecot] Maildir Index Question
by Ron Culler 06 Aug '08

06 Aug '08

We have several hundred mailboxes that have thousands of files in them (spam boxes) We currently run a find command and remove the files that are over 7 days old but still have boxes with upto 60k messages in them. I know that dovecot will update the index files for each mailbox when the boxes is accessed by an IMAP client(Webmail using Squirrel)but that can take quite a while to index. What I would like to do is via a cron job after the old file remove is to force dovecot to reindex these boxes. That way when the users login to the webmail interface it is quicker. Does anyone know if a script is available to do this? Thanks Ron Culler

[Dovecot] Dovecot PAM sessions with Maildir
by Sean Smitz 06 Aug '08

06 Aug '08

I am configuring a new mail server on RHEL 5 x64. I have configured dovecot as follows: ... protocols = imaps ... ssl_cert_file = /etc/pki/dovecot/certs/mailserver.cer ssl_key_file = /etc/pki/dovecot/private/mailserver.pem ... login_process_size = 64 ... mail_location = maildir:~/Maildir ... passdb pam { args = "session=yes cache_key=%u%s dovecot" } ... I'm getting the following error messages in /var/log/maillog: Aug 5 20:57:45 [hostname] dovecot: imap-login: Aborted login: rip=::ffff:128.8.244.15, lip=::ffff:[server], TLS Aug 5 21:01:34 [hostname] dovecot: imap-login: Aborted login: user=<[me]>, method=PLAIN, rip=::ffff:[server], lip=::ffff:[server], TLS I'm getting the following messages in /var/log/audit/audit.log: type=USER_AUTH msg=audit(1217984152.016:347): user pid=7669 uid=0 auid=10243 subj=user_u:system_r:dovecot_auth_t:s0 msg='PAM: authentication acct="[me]" : exe="/usr/libexec/dovecot/dovecot-auth" (hostname=::ffff:[client], addr=::ffff:[client], terminal=dovecot res=success)' type=USER_ACCT msg=audit(1217984152.017:348): user pid=7669 uid=0 auid=10243 subj=user_u:system_r:dovecot_auth_t:s0 msg='PAM: accounting acct="[me]" : exe="/usr/libexec/dovecot/dovecot-auth" (hostname=::ffff:[client], addr=::ffff:[client], terminal=dovecot res=success)' type=USER_START msg=audit(1217984152.017:349): user pid=7669 uid=0 auid=10243 subj=user_u:system_r:dovecot_auth_t:s0 msg='PAM: session open acct="[me]" : exe="/usr/libexec/dovecot/dovecot-auth" (hostname=::ffff:[client], addr=::ffff:[client], terminal=dovecot res=failed)' I find the message in the audit.log interesting because I configured the connection with SSL not TLS, but if I use TLS the result is the same.

[Dovecot] Dovecot proxying results in "too many open files"
by Gianpaolo Del Matto 06 Aug '08

06 Aug '08

Hi, Some words about my Dovecot setup: - 10 dovecot servers - each server has some local mailboxes - each server has proxying enabled to seamlessly connect to another host if the mailbox is not local Running Dovecot 1.1.1 on FreeBSD 6.3-RELEASE-p3. First of all, local mailbox access is fine. Proxying works also as expected. Now for the actual problem: Shortly after startup, Dovecot starts throwing errors concerning connection which should be proxied. Here are some examples from the logs: Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: accept() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:11 dovecot: imap-login: socket() failed: Too many open files [..] Aug 6 16:00:05 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:08 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:11 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:13 dovecot: imap-login: accept() failed: Too many open files As from the context it seems to be a file descriptor issue, as such I have done the following: - added a 'limits -e -n 32768 -U dovecot' to dovecot startup file to ensure it has enough FD's - additionally, I've checked my kernel file limits, however I always set it through loader and sysctl to be as large as 64k # sysctl -a |grep files kern.maxfiles: 65535 kern.maxfilesperproc: 32768 kern.openfiles: 1632 - also checked the limits of the dovecot user like this: # su -c dovecot root -c 'ulimit -a' core file size (blocks, -c) unlimited data seg size (kbytes, -d) 1048576 file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 32768 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 131072 cpu time (seconds, -t) unlimited max user processes (-u) 5547 virtual memory (kbytes, -v) unlimited - done some monitoring of file descriptor usage for the dovecot user, though somewhat inacurate, like this: while [ : ]; do date; fstat -u dovecot |wc -l; sleep 1; done this gave me these results while tailing the logfile: Wed Aug 6 15:44:12 CEST 2008 585 Wed Aug 6 15:44:13 CEST 2008 579 Wed Aug 6 15:44:14 CEST 2008 582 Wed Aug 6 15:44:15 CEST 2008 582 Wed Aug 6 15:44:16 CEST 2008 586 Wed Aug 6 15:44:17 CEST 2008 585 Wed Aug 6 15:44:18 CEST 2008 582 So it didn't seem to be anywhere near the theoretical upper limit I've set at 32k. On the other hand, when restarting Dovecot, it works for a few minutes for at least as long as the FD usage as reported above stays at around 500. I remember from the docs that dovecot-login would require the double amount of file descriptors to run. Assuming my report is somewhat inaccurate and lags behind, I could imagine that upon a proxy requests it would effectively peak our at some 500 x 2 FDs. Thus effectively reaching the 1024 FD barrier. I conclude this from the fact that I currently have some 350 - 450 logins in parallel, most of which can and shell be proxied. From the error message in the logs I got the impression, that only proxied connections are affected. I was not able to reproduce the issue with non-proxied logins to local mailboxes. Some further steps I've done from the configuration side to no avail: - disabled imaps/pop3s/ssl - changed between login_process_per_connection yes/no - played around with login_max_connections et all (raised/lowered) limits - tried with/without plugins enabled - tried with SQL-based and passwd-file based userdb/passdb, single and mixed Dovecot config: # dovecot -n # 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 listen: *, [::] ssl_disable: yes ssl_cert_file: /usr/local/etc/postfix/tls/server.crt ssl_key_file: /usr/local/etc/postfix/tls/server.key disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_processes_count: 16 login_max_processes_count: 64 login_max_connections: 64 max_mail_processes: 256 mail_max_userip_connections: 3 verbose_proctitle: yes mail_privileged_group: mail mail_uid: 1000 mail_gid: 1000 mail_location: maildir:~/Maildir fsync_disable: yes maildir_copy_preserve_filename: yes mail_drop_priv_before_exec: yes mail_executable(default): /mailserver/scripts/dovecot/imap mail_executable(imap): /mailserver/scripts/dovecot/imap mail_executable(pop3): /mailserver/scripts/dovecot/pop3 mail_plugins: expire mail_log mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 mail_log_max_lines_per_sec: 0 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra- mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra- mailbox-sep imap_client_workarounds(pop3): pop3_no_flag_updates(default): no pop3_no_flag_updates(imap): no pop3_no_flag_updates(pop3): yes pop3_enable_last(default): no pop3_enable_last(imap): no pop3_enable_last(pop3): yes pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private inbox: yes list: yes subscriptions: yes namespace: type: private separator: . prefix: INBOX. hidden: yes auth default: mechanisms: plain login cram-md5 cache_size: 131072 username_translation: #@/@%@ username_format: %Lu verbose: yes debug: yes debug_passwords: yes worker_max_request_count: 16384 passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: passwd-file args: username_format=%n /usr/local/etc/postfix/tables/ deliver_passwd userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vpostfix group: vpostfix plugin: expire: Trash 14 Trash/* 14 Spam 14 Spam/* 14 VirusAlerts 14 VirusAlerts/* 14 Quarantine 14 Quarantine/* 14 expire_dict: proxy::expire dict: expire: mysql:/usr/local/etc/dovecot-expire.conf Maybe I am missing something here.

[Dovecot] Dovecot auto vacation with sieve doesn't work
by CJ Keist 06 Aug '08

06 Aug '08

Guys, I'm running out of hair to pull out ;). Can anyone out there say that this does work?? To me this is looking like a bug and I'm not sure whether it's the sieve plugin or the dovecot deliver program. I have also had no luck the the "reject" sending any reply back to the sender. My setup: OS: Solaris 10 sparc platform postfix: 2.5.2 dovecot: 1.1.2 sieve plugin: 1.1.5 I'm going back forth between procmail and sieve and having no luck. procmail will send the reply to the sender but doesn't deliver the message to the recipient. Sieve will deliver the message to the recipient but doesn't send the reply to the sender. Now if I can just combine the two, I'll be in business. Postfix mail command: mailbox_command = /userM/mail-services/dovecot/libexec/dovecot/deliver -d $USER* * Dovecot -n (I've made some changes from my previous posting namely with the master_auth settings) # 1.1.2: /userM/mail-services/dovecot/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 3072).

[Dovecot] expire-plugin: configuration dict-server
by Jens Meyer 06 Aug '08

06 Aug '08

Hello all! I tried to add the expire-plugin to my dovecot-installation (CentOS-RPM: dovecot-1.1.1-2_76.el5) and followed the plugin-page from the WIKI (http://wiki.dovecot.org/Plugins/Expire) Unfortunately I have problems with the dictionary: --> dovecot: Aug 05 13:30:25 Error: dict: Unknown dict module: db dovecot: Aug 05 13:30:25 Error: dict: Failed to initialize dictionary 'expire' <-- As far as I understand the hints from mailinglist-archive the db-support is not standard with dovecot and Timo suggested to use a mysql-connection. Are there any further tipps how to use the expire-plugin with mysql-connection (i.e. database-scheme, SQL-Select)? Kind regards, Jens

[Dovecot] 1.0(.14) vs 1.1.2 performance
by Thomas Hummel 06 Aug '08

06 Aug '08

Hello Timo, I just switched from dovecot-1.0.14 to dovecot-1.1.2 and noticed a significant drop in the server load average (which has become lower and above all doesn't seem to have unexplained peaks). Indexes are still locally stored and nfs attribute caching is still off). I searched the list archives for an explanation of what changed in the code that could explain such an improvement but mostly (except maybe some index code rewrite mentions) found differences in features. Where does that performance gap come from ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Vacation reply with Procmail and dovecot deliver
by CJ Keist 06 Aug '08

06 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Giving up on the sieve plugin and switching to procmail. I found the following link: http://wiki.dovecot.org/procmail This site doesn't saying anything about needing to modify the procmail source code like here: http://dovecot.org/pipermail/dovecot/2006-July/014656.html Thos shows how to make procmail work with dovecot deliver program. So you create the following /etc/procmailrc file: # file: /etc/procmailrc # system-wide settings for procmail SHELL="/usr/bin/sh" SENDMAIL="/userM/mail-services/postfix/lib/sendmail" LOGFILE="/var/log/procmail.log" DELIVER="/userM/mail-services/dovecot/libexec/dovecot/deliver -d $USER" # fallback: DEFAULT="$HOME/mail" :0 w | $DELIVER So I modified postfix to call procmail (version 3.22): mailbox_command = /userM/mail-services/procmail/bin/procmail -Y -a $DOMAIN -d $USER So now I'm getting the vacation reply sent to the sender (Yea!!!), but the message is failing to get to the recipient. In the procmail log file I see: Fatal: Missing -d argument procmail: Program failure (64) of "/userM/mail-services/dovecot/libexec/dovecot/ deliver" - From someaccount(a)yahoo.com Tue Aug 5 15:21:09 2008 Subject: test 7 procmail Folder: /top/admin/ENS/people/cjay/home/mail/msg.qX_ 1878 Has anyone got this setup working?? - -- C.

Hmm.. shouldn't be any flags needed besides --with-mysql and --with-sql. I wonder if it has to do with the namespace. Try changing expire: Trash 2 to expire: INBOX.Trash 2 I'm not sure how (if) namespaces effect the expire plugin. Timo may be able to shed more light.

[Dovecot] Corrupted transaction logs

Hi, I'm getting a lot of the following messages in my mail.err log. Jul 12 11:25:51 mink dovecot: IMAP(user1(a)domain1.net): Corrupted transaction log file /virtual/store1/mail/u/user1_domain1.net/Maildir/.Sent/dovecot.index.log: Append with UID 925, but next_uid = 926 Jul 12 12:44:56 mink dovecot: IMAP(user2(a)domain1.net): Corrupted transaction log file /virtual/store2/mail/u/user2_domain1.net/Maildir/.Trash/dovecot.index.log: Append with UID 4927, but next_uid = 4931 Jul 12 12:45:19 mink dovecot: IMAP(user2(a)domain1.net): Corrupted transaction log file /virtual/store2/mail/u/user2_domain1.net/Maildir/.Trash/dovecot.index.log: Append with UID 4930, but next_uid = 4931 The users get the wrong headers and bodies being displayed in Thunderbird and I'm unsure of the symptoms in other browsers. I'm running two mail servers with two NFS servers for the mail stores. Both mail servers have access to both mail stores and I'm assuming that that is what's causing the problem. I'm running dovecot 1.0.10 (Ubuntu - so I'm using only packages provides by aptitude at the moment). Should dovecot be able to handle access by multiple machines for the indexes? Thanks Guy -- Don't just do something...sit there!

Run it with a --test and it should tell you what it is doing. Did it remove the message from the Trash too as well as the db entry?

[Dovecot] Expire plugin with Mysql
by Eric 05 Aug '08

05 Aug '08

Hey guys, got a question about the expire plugin. According to the wiki, the expire plugin "keeps an internal database (Berkeley DB or SQL)". I was wondering what fields in the mysql table are needed for expire to work. I assume it is setup is similar to the quota dict setup, so was just wondering what fields are required (i.e: select_field, where_field, username_field, for quota). Thanks

[Dovecot] dovecot-auth requires userdb, but already configured
by Carl Vondrick 05 Aug '08

05 Aug '08

Greetings! My ultimate goal is to have fetchmail/getmail poll from POP3/IMAP servers and deliver mail into Dovecot mailboxes. This does not work because the Dovecot LDA for some reason fails. I believe I have narrowed down the problem to dovecot-auth not finding my userdb. But, I am able to connect to dovecot via IMAP in my MUA and preform operations (read, delete mail, create folders). This leads me to believe my userdb is setup correctly. Does anyone have any idea as to why dovecot-auth would not find my userdb? (Configuration is below). carl@cvondrick:~$ dovecot --version 1.0.10 carl@cvondrick:~$ /usr/lib/dovecot/dovecot-auth dovecot-auth: Fatal: You'll need to add at least one userdb carl@cvondrick:~$ dovecot -n # 1.0.10: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log ssl_disable: yes disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: mbox:/home/carl/mail/%u mail_debug: yes dotlock_use_excl: yes auth default: verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd-file args: username_format=%u /etc/dovecot/passwd carl@cvondrick:~$ uname -a Linux cvondrick 2.6.24-20-generic #1 SMP Mon Jul 28 13:06:07 UTC 2008 x86_64 GNU/Linux The package is from Ubuntu Hardy, but I can build from source if you think it'll fix this.

[Dovecot] FTS/squat search indexes built when?
by Jay Levitt 05 Aug '08

05 Aug '08

I know that a given search index doesn't get built the first time until you do an actual search on it from an IMAP client. I don't much care about that; I'm the only user, and I don't create new folders too often. At worst, I could create a script to go search every folder once. But what I'm not clear about: Does it then get updated on every delivery by LDA? Or does the index also need to get updated when I do a search, assuming there's been at least one message delivered since the last search? Jay Levitt

[Dovecot] doveot reporting "No space left on device" - yet df show plenty of space / inodes.
by Tom Brownlie 05 Aug '08

05 Aug '08

Hi, I am running dovecot 1.0.rc7 on a Suse Linux server. The server has approx 200+ mailboxes. Last week the filesystem (/dev/mapper/datavg/dat2lv) ran out of space - causing it to do into read-only mode. When I realised this I allocated some more space and re-booted the machine... Strangely it seems that dovecot is still having problems... It's like dovecot doesn't realise that there is enough space on the file system. Also - it only is happening to a few users at this stage - not all users are having problems sending/receiving emails... The dovecotstderr.log file contains: dovecot: Aug 05 09:47:38 Error: IMAP(rebecca): file_dotlock_open(/data/mail/rebecca/dovecot-uidlist) failed: No space left on device When I do a df -h mail:/var/log # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda4 9.0G 5.7G 3.3G 64% / tmpfs 491M 8.0K 491M 1% /dev/shm /dev/mapper/datavg-dat2lv 300G 130G 171G 44% /data When I do a df -i mail:/var/log # df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda4 0 0 0 - / tmpfs 125505 5 125500 1% /dev/shm /dev/mapper/datavg-dat2lv 357753312 1030354 356722958 1% /data I manually created a file in /data/mail/rebecca - which worked fine, and didn't cause any problems. HELP!!! I am stumped.... I can't understand why Dovecot is complaining.. I have manually stopped postfix and dovecot, and then re-started them.. But to no avail. HELP - I am desperate.... My previously very reliable email server seems to be sick.. _________________________________________________________________ Meet singles near you.

[Dovecot] sieve multiple redirects
by Anil 05 Aug '08

05 Aug '08

I got a sieve script like this: redirect "user(a)gmail.com"; redirect "someuser(a)hotmail.com"; keep; It seems to redirect the mail to the 1st user but not the 2nd. Any idea? From what I can tell, that is a valid sieve script. I am using an earlier RC version of dovecot - 1.1.rc4, going to be upgrading soon. There are also a few errors.

[Dovecot] RFE: Disallow DELETE of non-empty MBOX
by Kenneth Porter 05 Aug '08

05 Aug '08

It looks like this is already the rule for maildir, where one can't remove the folder if any files or subdirectories are present. I'd like to get this option for mbox folders, as I'd like to prevent "accidents" where users accidentally delete large folders by clicking the wrong thing and then too-quickly approving the confirmation dialog that pops up. (Impatient upper level management tends to do this. ;)) BTW, I'm using Mulberry for my client, and it unfortunately puts "Mark contents seen" right next to "Delete folder" on the context menu. I'm aware of the issue so I tend to be extra careful when I finish with the folder associated with a busy mailing list and mark all the uninteresting messages seen.

[Dovecot] v1.1.2 released
by Timo Sirainen 04 Aug '08

04 Aug '08

http://dovecot.org/releases/1.1/dovecot-1.1.2.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.2.tar.gz.sig Development of new features in this release and the upcoming multi-master replication are sponsored by Directi (www.directi.com) Lucene indexing is currently deprecated in favor of the new Solr indexing. I'm even considering removing the Lucene C++ library support, so if you're interested in keeping it send me a mail. Note that the current fts-lucene is somewhat broken as well as non-optimal. Anyone interested in using zlib plugin with Maildir should read http://wiki.dovecot.org/Plugins/Zlib. I'm hoping to get the first v1.2 betas out in a couple of weeks and an eventual v1.2.0 release in a couple of months. + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed - mbox: Fixed an assert-crash with \Recent flag handling

[Dovecot] bugzilla or other similar bug tracking systems
by Diego Liziero 04 Aug '08

04 Aug '08

I was wondering if it could be useful to use such tools to keep track of users bugs. I find somehow harder to search the mailing list if a bug is known, if it's being worked on, if it needs more feedback, in witch release it has been eventually solved, and so on. Any thoughts? Regards, Diego.

This problem is apparently about changeset http://hg.dovecot.org/dovecot-1.1/rev/eec74a6ad62e. This change makes dovecot behaviour different from what is described in wiki, about sharing and making private /Seen flags, see http://wiki.dovecot.org/SharedMailboxes?highlight=(flags are shared or private) When I've tried to revert it, first time with my client it worked perfectly.

[Dovecot] plus addressing bug in dovecot 1.1.x?
by Jon Fullmer 04 Aug '08

04 Aug '08

I had recently upgraded from Dovecot 1.0.14 to 1.1.0, and then to 1.1.1. Ever since the upgrade to 1.1.0, I noticed that "plus addressing" has failed. In case I'm using a foreign phrase, this is the concept of sending an e-mail to "user+spam(a)domain.com", and having dovecot (dovecot LDA, specifically), deliver this to the "spam" submailbox to "user(a)domain.com". I've been using this successfully since 1.0.3. When I upgraded to 1.1.0, I noticed that e-mails were no longer being delivered to the submailboxes as they had been (though they would arrive in the central INBOX). I checked the "dovecot-deliver.log", and I noticed that, ever since I had brought up 1.1.0, I would see: save failed to spam: Unknown namespace ("spam" is the submailbox) After the upgrade to 1.1.1, I still would see these messages (and behavior). I have since installed 1.0.15. The plus addressing now works again, as it had been. With all of these "upgrades" and "downgrades", the config file has remained exactly the same. There have been no other changes to any components on the host system (i.e., new OS-es, new postfix, etc.). Thoughts? Is this a known issue? - Jon

[Dovecot] Recieving e-mail is not updating quota
by M. Rodrigo Monteiro 04 Aug '08

04 Aug '08

Hello again. When I send e-mail locally from userX@mydomain to userY@mydomain the quota in userY@mydomain isn't updated with the new message, but the message arrives fine. It's not a userX problem, because it's equal if it's userY sending userX. When I save an message, the quota is updated. Or when the userX sends the e-mail, his quota is updated too. The problem is that the quota don't update when a new message arrives. What could it be? Now I empty the mailbox of the userY, and the maildirsize is like this: 16777216S 0 0 1151862 1 2837616 1 2838683 1 5674797 2 -5674797 -2 -5674797 -2 1151862 1 -1151862 -1 -1151862 -1 The user quota from ldap is 16MB. In the user dir, the size is 452K # du -kh . --max-depth=0 452K . Now, I send an e-mail about 900k from userX to userY, and the quota display still 0M, but the user dir is 1,6M # du -kh . --max-depth=0 1,6M .

[Dovecot] namespaces at v1.0.15
by Evaggelos Balaskas 04 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, i need to create a public maildir folder for virtual users so i did this: dovecot-1.0.15: namespace public { prefix = public/ separator = / location = maildir:/var/mail/shared:INDEX=/var/mail/shared/%u/index/:CONTROL=/var/mail/shared/%u/control/ } namespace private { separator = / prefix = inbox = yes } umask = 007 and everything works fine, but ... when one user reads an email from the public folder then the status (flag read) changes to all users. How i can fix this? How every virtual user (same uid.gid) can have its own index (perhaps?)

[Dovecot] 1.1.2 segfaults when using passdb passwd and md5 mechanism
by Miguel Filho 04 Aug '08

04 Aug '08

Setting passdb to passwd and enabling cram-md5 or digest-md5 makes dovecot crash. The documentation says that I can use md5 with passwd. I had to use strace to figure it, because dovecot segfaults and doesn't log the error.

[Dovecot] Dovecot doesn't read users and passwords from config files
by Marco Fioretti 04 Aug '08

04 Aug '08

Greetings, I am setting up Dovecot 1.0.15 on my home Fedora Core 8 pc ONLY to access my mail archives across several mail clients. No access from the internet is possible or needed here. I cannot log in with any client, the login always fails. The reason, as I understand, is that when dovecot starts it doesn't read any user name from the userdb file, so when I try to login it doesn't recognize my name and so doesn't even try to verify the password: maillog excerpt: Aug 3 00:06:11 polaris dovecot: Dovecot v1.0.15 starting up Aug 3 00:06:11 polaris dovecot: auth(default): passwd-file /etc/local_dovecot_passwords: Read 0 users Aug 3 00:06:11 polaris dovecot: auth(default): passwd-file /etc/local_dovecot_users: Read 0 users Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5150 Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5148 Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5149 Aug 3 00:06:26 polaris dovecot: auth(default): client in: AUTH#0111#011PLAIN#011service=IMAP#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011resp=AG1hcmNvAGdpZ2V0dG8= Aug 3 00:06:26 polaris dovecot: auth(default): passwd-file(marco,127.0.0.1): lookup: user=marco file=/etc/local_dovecot_passwords Aug 3 00:06:26 polaris dovecot: auth(default): passwd-file(marco,127.0.0.1): unknown user Aug 3 00:06:27 polaris dovecot: auth(default): client out: FAIL#0111#011user=marco Aug 3 00:06:27 polaris dovecot: imap-login: Disconnected: user=<marco>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured the dovecot.conf file, purged by comments, is below.

[Dovecot] Server power loss and "Dovecot is already running with PID xxx"
by Pekka Savola 04 Aug '08

04 Aug '08

Hi, I'm running Dovecot 1.0.7 (with various patches) on CentOS 5.2. The server has suffered a couple of power loss events. Dovecot is run as a standalone server. The problem is that dovecot refuses to start up at boot because the PID file from before the power loss is left behind. The message is as follows: $ /sbin/service dovecot start Starting Dovecot Imap: Error: Dovecot is already running with PID 10825 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] (Note: there is nothing wrong in the configuration file so the error message is somewhat misleading.) I looked at the release notes of 1.0.xx releases and they didn't mention this. Is this already a known problem? Should the start-up logic be made more robust (e.g. check whether a process corresponding to the PID actually exists)? -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."

[Dovecot] related, but off-topic: how to allow users to change password?
by Sahil Tandon 04 Aug '08

04 Aug '08

My dovecot is currently configured to authenticate vs. a userdb/passdb passwd-file that contains, for each user: username:passhash:5000:5000::/path/to/home::userdb_mail=/path/to/maildir Is it possible to let users authenticate and change their passwords? There are some webmail client add-ons that allow such things if users are system accounts or in a MySQL/LDAP db. Does anyone else use passdb/userdb passwd-files like above and have a method for allowing users to change their passwords from the web? Sorry for the slightly off-topic question, but hoping another Dovecot admin has solved this problem. Preference is to not to be tied to any particular webmail client just for this change password feature.

[Dovecot] Thunderbird and Dovecot on FC5 taking a long time to retrieve message
by Bruen, Mark 02 Aug '08

02 Aug '08

I'm running FC5 (2.6.15-1.2054_FC5smp) and Dovecot dovecot-1.0-0.beta8.2.fc5 with Thunderbird 2.0.0.16. I set up imap (dovecot) so I can access my mail locally or remotely. It seems to take a very long time (minutes sometimes) for an Email to be retrieved after I select it in the folder list and/or in the Email list locally or remotely. I've traced the imap process and found it doing a lot of reading (read() system calls) for a long time. I do have a high message count in some of these folders (i.e.: 20000 or so). Is there any way to improve performance (use more memory, cache indexes, tune I/O parameters, etc...) ? Thanks. -Mark

[Dovecot] POP3 locking
by Adrian Overbury 02 Aug '08

02 Aug '08

I'm trying to understand what dovecot's behavior will be in a given scenario to see if it will work as a (hopefully better) replacement for the home-grown pop3 server we currently use. User A is on a slow dialup connection, and uses, oh, let's say Outlook, since that's where most of our problems seem to spring from. User A uses outlook to download his mail over pop3. Half way through downloading a particularly large message, Outlook decides that the whole process isn't happening fast enough, so it opens another connection to the server and tries to download (potentially) the same message again. Now, our current server establishes a lock on the mailbox, and when that second connection happens it simply responds that there's no messages to collect... we used to have it terminate the connection, but this brings up confusing error messages on User A's client, and they call up and complain -- not an ideal situation. I've got a dovecot installation on my testing server, and I think I've set everything up correctly; it authenticates from my LDAP database, finds the home directory, lists the mail, all that... I believe somewhere it there it uses fcntl to establish an advisory lock on the mailbox (oh, we're using Maildir, by the way). I'm not sure where, though, or how long the lock persists for, or what its actual purpose is, because my tests show me that I can log the same users in with two concurrent sessions and get the same message twice. It's probably a fault in my understanding of how locking in user sessions of a pop3 server should work, but that doesn't sound right to me. Can someone explain if what I'm seeing is correct, or what problem it may be symptomatic of? Does dovecot even do concurrent-user-session locking? So far I've enjoyed playing with dovecot -- far more than the current server we use. I'd like to use it as our primary pop3 server, but preventing users from having concurrent sessions and getting the same message more than once, and keeping them from seeing errors because of their client trying to open multiple sessions is important. Oh, and I'm user dovecot 1.0.beta3, since I don't really have the option of upgrading the OS on my mail servers any time soon. Adrian

[Dovecot] Quota warnings wrong behaviour (1.1.2)
by Włodek Waligórski 02 Aug '08

02 Aug '08

Hi, I use the latest version of dovecot 1.1.2. Thanks to the excellent docs I managed to get everything working so far, but ... I'm experiencing such strange behaviour when user gets over 90% of quota (the threshold is such): 1. user uses say 89% of his ~/Maildir 2. message arrives that increases quota usage to 92% 3. quota_warning is _NOT_ triggered 4. user deletes the surplus message and gets back to 89% (quota_rule2: Trash:ignore) 5. quota_warning is triggered and quota warning message arrives So the event gets triggered when user passes the quota threshold, but from a "wrong direction". I would expect that message should arrive together with the surplus message. Below I paste my dovecot.conf and "./configure" opts: -------------------cut--------------------------------------- # dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf base_dir: /usr/local/var/run/dovecot/ log_path: /dev/stderr info_log_path: /dev/stderr log_timestamp: listen: 127.0.0.1:143 ssl_listen: 0:993 ssl_cert_file: /var/qmail/control/servercert.pem ssl_key_file: /var/qmail/control/servercert.pem ssl_cipher_list: ALL:!LOW verbose_ssl: yes login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 mail_uid: vpopmail mail_gid: vchkpw mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle auth default: user: vpopmail verbose: yes debug: yes passdb: driver: vpopmail args: quota_template=quota_rule=*:backend=%q userdb: driver: vpopmail plugin: quota: maildir quota_rule: ?:storage=110485760 quota_rule2: Trash:ignore quota_warning: storage=90%% /usr/local/bin/imap-quota-warning 90 ----------------------------------------------------------------------------------- # grep "./configure" config.log | head -1 $ ./configure --disable-ipv6 --without-passwd --without-passwd-file --without-shadow --without-pam --without-checkpassword --without-bsdauth --without-gssapi --without-sia --without-ldap --with-vpopmail --without-static-userdb --without-prefetch-userdb --without-sql --without-pgsql --without-mysql --without-sqlite --with-ssl=openssl ------------------------------------------------------------------------------------ My system is x86 Debian-testing, SMP. -Włodek

[Dovecot] Permission denied creating inbox file in /var/mail
by Steve Ochani 01 Aug '08

Hello all, I'm using dovecot version 1.07 on CentoOS 5 (clone of RHEL 5). When there is no existing mbox file for a user in /var/mail I get the following error: --------------- Jul 31 16:32:32 newnewton dovecot: imap-login: Login: user=<testm2>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): open(/var/mail/testm2, O_CREAT) failed: Permission denied Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): access() failed with mbox file /var/mail/testm2: No such file or directory Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): stat() failed with mbox file /var/mail/testm2: No such file or directory Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): Connection closed ---------------- My persimmons on /var/mail (which is a symlink to /var/spool/mail) : drwxrwxr-x 2 root mail 4096 Jul 31 16:32 mail I have tried adding the mail group as mail_privileged_group, the output of dovecot -n : -------------------- # 1.0.7: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:~/IMAPmail:INBOX=/var/mail/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd -------------------- Here is the permission on /etc/dovecot.conf -rw-r--r-- 1 root root 42833 Jul 31 15:30 /etc/dovecot.conf I've searched google and the mailing list archive and tried the couple of things commonly suggested. As for a test I changed perms on /var/spool/mail to 777 and then dovecot made the inbox file. The file ended up being owned by the user and the group owner was the group that the user belongs to, not mail. When I create new users using useradd there is a 0 byte file created in /var/mail for the user but I use scripts to create student accounts every semester (about 10,000) so I'm trying to avoid having to add more things that the script will have to create. Any help is greatly appreciated. Thanks -Steve O.

[Dovecot] dovecot.sieve file location?
by kbajwa 01 Aug '08

01 Aug '08

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5 I have setup with: home_mailbox = Maildir/ (/etc/postfix/main.cf) & mail-location = maildir:~/Maildir (/etc/dovecot.conf) I have created a 'test' user to test Sieve 'Vacation' setup. My questions are: 1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else? 2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'? Kirti

[Dovecot] Dovecot load balancing
by Thomas Hummel 01 Aug '08

01 Aug '08

Hello, I'd like to figure out how to set up a site running dovecot on multiple computers for load balancing reasons. I'm currently running dovecot-1.0.14 on a 8GB RAM, 2 quad-core 2.66Ghz Xeon single server which runs FreeBSD 6.2-STABLE SMP. . the mailbox format was mbox and I successfully migrated to Maildir only . mailboxes are on an NFS NetApp server, attribute caching is off . indexes are locally stored . the number of users is around 2500, some of them having huge mailboxes (~ 1 or 2 GB) . a large amount of users is using IMAP but there are also many POP3 users . the passdb/userdb is openLDAP . for now, I neither use namespaces, nor quotas nor deliver, nor any plugin, but I plan to use namespaces and ACL to implement shared mailboxes. The same machine is running postfix-2.4.6 with amavisd-new-2.5.4 (no spamassassin) and clamav-0.93.1. I'm using procmail-3.22 as the LDA. I installed dovecot-1.1.2 on non-standard ports for test and plan to switch to it as I read on this list it performs better, load wise. This setup (1.0.14) works great except that, compared to the time mailboxes were in mbox format, the load average (as shown by 'top') goes higher from a significant amout on a regular basis and sometimes goes over the top. On "normal" circumstances, the number of processes is around 1400 and the load oscillates between 1 to 10 and 30 to 60. Most of the time, I'd say the load average is around 20. Every friday a message (no attachement, decent size) is sent to all users : in such circumstances (but only sometimes, not every time : let's say half the time such a message is sent), the load goes so high that I have to stop dovecot to let procmail deliver the message or even reboot the machine. Sometimes, the load climbs up to something like 150, then goes back to the 'normal' case described above. I know multi-master replication is on the roadmap. I know some dovecot sites use in the meantime several dovecot servers. I'd like to know how those sites do the load balancing, the main problem beeing to be able to direct each user to the same dovecot server each time as stated in the Wiki (http://wiki.dovecot.org/NFS) I don't think that DNS round robin would do the trick because some UA (for instance Thunderbird) often open up to 5 connexions for the same user, unless maybe such UA makes a single 'gethostbyname()', thus connecting 5 times to the same physical server ? What are the options to achieve such a setup ? Any successful experiences ? Thank you -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] One LDAP attribute for many variables
by Juan Asensio Sánchez 31 Jul '08

31 Jul '08

Hi Using Dovecot 1.1.2 with LDAP. If i have this: user_attrs = uid=home=/var/vmail/%$,mailuserquota=quota_rule=*:storage=%$,=mail=maildir:/var/vmail/%n/Maildir OK. But if i have this: user_attrs = uid=home=/var/vmail/%$,mailuserquota=quota_rule=*:storage=%$,uid=mail=maildir:/var/vmail/%$/Maildir I get this error: deliver(usuario1): Jul 25 12:59:08 Error: Per-user script path is unknown. See http://wiki.dovecot.org/LDA/Sieve#location The only difference is that I use the uid LDAP attribute twice. Why does this happen?

[Dovecot] Seen flag in maildir filename not being respected
by Eduardo M KALINOWSKI 31 Jul '08

31 Jul '08

Hi, I'm using dovecot 1.1.2 (but I've noticed this since 1.1.1 which I was using until yesterday). It seems dovecot is ignoring the "S" flag in Maildir filenames, and is relying only in its Index Files to determine if a message has been read or not. I say that because if I delete the dovecot.index.* files for a mail folder, all the mails in there appear as unread. Also, I've tried accessing the maildir directly (using heirloom-mailx, but mutt should have done, too) and reading a new message. The file name was changed to add a "S" to the end, but this message was still marked as "unread" when the mail folder was accessed via IMAP. The flags R, F and T are correctly read from the filename if no index is present. I haven't tested the other flags. I'm using dovecot's deliver, and it creates filenames such as "1217450416.M77457P5201.mail.kalinowski.com.br,S=1377,W=1411:2,S", that is, perfectly fine. dovecot -n: # 1.1.2: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/server.pem ssl_key_file: /etc/ssl/private/server.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: username_format=%n /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: mail plugin: quota: maildir quota_rule: ?:storage=0 quota_rule2: Trash:ignore quota_rule3: Spam:ignore quota_rule4: Spam.Errado:ignore sieve: /home/vmail/%d/db/sieves/%n.sieve

[Dovecot] wrong permission
by Cor Bosman 31 Jul '08

31 Jul '08

Im still finding a number of control directories that have the wrong permission: Jun 26 00:02:34 userimap13.xs4all.nl dovecot: IMAP(xxx): file_dotlock_create(/var/spool/mail/dovecot-control/g/gl/xxx/INBOX/.Apple Mail To Do/dovecot-uidlist) failed: Permission denied userimap1# ls -al "/var/spool/mail/dovecot-control/g/gl/xxx/INBOX/.Apple Mail To Do" total 8 drw------- 2 xxx user 4096 May 12 23:43 . drwx------ 7 xxx user 4096 May 12 23:43 .. This folder was created May 12, well after us starting to use 1.1RC versions. I currently fixed a few hundred of these (out of millions of folders), and whats interesting is that a very large percentage of those (1/3th) is the folder "Apple Mail To Do", created by Mail.App I think. Obviously that same folder is no where near 1/3th of our total folder number, so thats a bit strange. I really doubt this is some local setting issue, because then id see much more of those. Right now it's a tiny fraction of our total folder amount, which leads me to believe it's some weird edge case in the dovecot code. Anyone have any ideas? Cor

[Dovecot] dovecot-imap displays empty domainalias mailboxen
by Kacper Wysocki 31 Jul '08

31 Jul '08

Hi folks, I'm using dovecot 1.0.13 as the IMAPS frontend for a vpopmail/qmail virtual domain setup. Dovecot is set up as follows: passdb vpopmail{ } userdb vpopmail{ } I've added a domain alias for the main domain with vaddaliasdomain and email to post@aliasdomain is delivered to post@maindomain and can be checked with pop. However, when I try to check IMAP through the account post@aliasdomain I am confronted with an empty mailbox. If I log in using post@maindomain I get the expected contents. Why can't my users log in using user@aliasdomain to check their emails? Regards, Kacper Wysocki -- http://kacper.doesntexist.org http://windows.dontexist.net There is symmetry in chaos, and chaos in excessive order. Though you may see heaven or hell, remember that it is your mind which creates them. Avoid grasping the one or fleeing the other.

These (in .../Maildir/cur) are your problem - someone created a Maildir underneath Maildir/cur, and dovecot or some other software considered the three directories messages, and goofed up. Check your delivery recipes so that none deliver to .../Maildir/, if you find any, adjust them deliver to .../Maildir/ instead. I'd suggest to: cd /home/matthew/Maildir/cur # move potential messages out to the proper new/... directory # if mv complains about nonexistent .../*, all the better! mv 'cur:2,ST/'* 'new/'* 'tmp:2,ST/'* ../new/ # get rid of the bogus directories rmdir '???:2,ST/' new cd - and see if that fixes the problem. If rmdir fails because there are hidden files, see what they are and where to move them, if the {cur,tmp}:2,ST or new are empty, fine, someone accidentally ran maildirmake with bogus arguments.

[Dovecot] .files in dovecot-1.1.1
by John Baker 31 Jul '08

31 Jul '08

Hi there We had been using the stock Ubuntu Dapper Dovecot which is an early 1.0 beta but just upgraded to 1.1.1 to fix some read flag issues with Horde. Previously dovecot seemed to ignore files beginning with "." in the ~/mail (mbox format) directory but now shows them. There doesn't seem to be any switch in the dovcot.conf file to change this. Any such settings are about maildir. Is there anyway to make dovecot-1.1.1 ignore hidden files?

[Dovecot] login processes from attacks staying for hours
by Kai Schaetzl 31 Jul '08

31 Jul '08

I'm in the process of rolling out new setups with dovecot on CentOS 5.2 and I notice that dovecot doesn't handle the brute-force attacks too nice. I reduced the limit a bit to some reasonable looking value: login_max_processes_count = 32 to stop them earlier and the number of processes stops at that figure when an attack happens. However, it stays at this count for hours although the attack is already over since long. For instance, my monitoring alerts me at the moment when the process count for pop3-login goes over 20 processes. This happened on three machines at 2 am with a brute-force attack from the same source that didn't last longer than a minute or so. However, the process count dropped only at 7am under 20 on two machines and on the third machine it was still over 20 when I was in the office at 9 am and finally killed them. As these machines are all not in production yet, there weren't any other logins and the single brute-force ended within one minute according to the logs (obviously when pop3-logins hit the limit). Shouldn't these processes go down to login_processes_count (3) within a few minutes? An strace shows that they are mostly doing gettimeofday lookups (=sleeping). This is the default dovecot (1.07) coming with CentOS 5.2. I've been running only one other instance of dovecot in production (0.99.11) on CentOS 4.6 so far and I don't know which behavior that displayed in the past as I just recognize that I accidentally ommitted it from monitoring. :-( I had this mailing list searched for "brute-force" to see how others handle this and what dovecot provides to stop these attacks. I have found not many threads about this. There is one with a bit more information: "Delay on failed pw attempts" from January 1. Unfortunately, this functionality is only in a later version of dovecot and it's not clear if it was implemented or not or if it would be helpful. Was it implemented? This thread also mentions fail2ban which may be one way to go, although I don't like this log parsing approach too much. Does anyone use iptables for rate-limiting per IP on the pop/imap ports to prevent brute-force attacks?

[Dovecot] installing plugin (autocreate_plugin.c)

Hi I want to enable autocreate-plugin, I downloaded http://dovecot.org/patches/1.1/autocreate-plugin.c compiled as specified in comment and got autocreate_plugin.so but I'm not sure how do I install it. I have many plugins in /usr/local/lib/dovecot/ (it's FreeBSD) and subdirs, but they all have libXX_ prefixes (what do they mean?). I couldn't find any information about installing plugins on dovecot's wiki and I don't want to experiment as the server is live (not really important but still live). regards -- Marcin Gryszkalis, PGP 0x9F183FA3 jabber jid:mg@fork.pl, gg:2532994 http://the.fork.pl

[Dovecot] DoveCot IMAP and "inconsistent state" messages
by Chris Richards 30 Jul '08

30 Jul '08

I need some help troubleshooting this problem. It only shows up with IMAP connections. I initially thought it was related to SquirrelMail (because it gives me an 'EXPUNGE' error), but after attempting to send IMAP commands directly to the server as shown below, I'm thinking there is something else going on. The system configuration is PostFix as the MTA delivering to procmail in the mailbox (maildir format), with Dovecot handling POP3 and IMAP Postfix is version 2.3.3 Dovecot is version 1.0.rc15 procmail is version 3.22 2001/09/10 kernel is 2.6.18-53.1.14.el5, CentOS 5 There is additional info about the system configuration after the command sequence and log entries below. I've left my typos in, just in case they somehow bear on the problem. I omitted about 2050 messages from the mailbox FETCH listing, since they were all identical but for the message number, and I didn't figure you'd want to read all of that. :) Command sequence: [me@myserver~]$ telnet locahost 143 locahost/143: Name or service not known [me@myserver~]$ telnet localhost 143 Trying 127.0.0.1...

Is there a better/preferred way to have Postfix/procmail deliver mail to the maildir that will keep Dovecot IMAP happy? (There don't seem to be any issues with pure POP3 access). Thanks in advance for your help, and if there's anything else you need to know that I can provide, please ask. I've tried to provide as much information up front as I can. Later, Chris

[Dovecot] limiting the per-time connections from one single IP address
by suomi 28 Jul '08

28 Jul '08

Hi every we had a havy pop3 attach yesterday morning: about 400'000 connects in three hours from one single IP address within wandadoo.fr. the easiest way, to protect the dovecot server against such attacks would be to limit the number of connections anyone can open from one single IP address to the server in a certain time. this feature is available in newer versions of postfix, where i have limited the number of SMTP connections possible from one single IP address in one minute to three (3). i checked to see in the dovecot-wiki, but found only the #login_max_processes_count = 128 #login_max_connections = 256 which both do not contain neither a per-time constraint nor a per-IP-address constraint. is this already possible with current versions of deovecot? the dovecot -n: # 1.0.14: /etc/dovecot.conf ssl_cert_file: /etc/pki/ldap/mirador.cert.pem ssl_key_file: /etc/pki/ldap/mirador.key.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 51 mail_location: maildir:%h/%m mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: ldap args: /etc/openldap/dovecot.conf userdb: driver: ldap args: /etc/openldap/dovecot.conf thank you very much for any valid hint. suomi

[Dovecot] Strange checkpassword issue
by Andy Dills 28 Jul '08

28 Jul '08

I'm helping a friend setup a small mailserver using dovecot, and I'm finding a strange problem with checkpasswd that I haven't had on my servers. How is the following debug output even possible? Jul 25 12:12:20 company2 dovecot: auth(default): master out: USER 5 joe home=/var/mail/joe.com/joe/Maildir/ uid=1005 gid=1005 Jul 25 12:12:20 company2 dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 25 12:12:20 company2 dovecot: POP3(joe): open(/var/mail/joe) failed: Permission denied (euid=1005 egid=1005) I don't see how, when it's clearly getting the correct home directory from checkpassword, that it would then try the default mail directory. (mail_location is commented out, version 1.1.1) Here's the entire auth clause: auth default { mechanisms = plain login passdb checkpassword { args = /usr/local/sbin/checkpassword } userdb prefetch { } user = mailman # 1005,1005 socket listen { master { mode = 0666 } client { path = /var/run/dovecot/auth mode = 0660 user = postfix group = postfix } } } Any suggestions? I'm probably just missing something obvious, not having messed with setting this up for 6 months. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

Hello, I'm using dovecot 1.1.1 and dovecot-sieve-1.1.5 . I'm very interested in the notify plugin, I've tried many code which have generated some errors (coding errors that have been arrived in the .dovecot.sieve.err) but these errors are fixed. But Notify is still not working, I've the following in mail.log :deliver(webmaster@xxx.net): SIEVE ERROR: Unknown [unimplemented] notify method mailto:phxxx@xxp.comhere is my .dovecot.sieve :require ["fileinto", "notify"];# Move spam to spam folderif exists "X-Spam-Flag" { fileinto "spam"; # Stop here so that we do not reply on spams stop;}notify :method "mailto:phxxx@xxp.com":message "Vous avez recu un message sur votre adresse"; # Don't send any further notifications stop;What's wrong? I've tried example from http://www.ietf.org/internet-drafts/draft-ietf-sieve-notify-12.txt but they are not working.Thanks for helpPhilippe _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

[Dovecot] odd pam_authenticate() failed: authentication error followed by successful imap-login

I am seeing the following errors in my log: Jul 27 18:14:23 aegis dovecot: auth-worker(default_with_listener): pam(user(a)host.org,74.72.46.170): pam_authenticate() failed: authentication error Jul 27 18:14:23 aegis dovecot: imap-login: Login: user=<user(a)host.org>, method=PLAIN, rip=74.72.46.170, lip=206.251.255.39, TLS This happens *only* for virtual users; local UNIX users authenticate without that first error. However, all users are able to view mail, but that default_with_listener (which I setup just so Postfix could use dovecot to authenticate SASL senders) error only occurs for virtual users. Why is default_with_listener getting involved when users are trying to connect to dovecot directly without any involvement of Postfix?

[Dovecot] dovecot.sieve file location?
by kbajwa 28 Jul '08

28 Jul '08

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5 I have setup with: home_mailbox = Maildir/ (/etc/postfix/main.cf) & mail-location = maildir:~/Maildir (/etc/dovecot.conf) I have created a 'test' user to test Sieve 'Vacation' setup. My questions are: 1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else? 2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'? Kirti

[Dovecot] mail extra field to override default mail_location for only certain users
by Sahil Tandon 27 Jul '08

27 Jul '08

I am running version 1.1.1 with mail_location: maildir:~/Maildir. This is working great as all our users have UNIX accounts with nologin shells. New domains (and their users) are about to come online and we would like to migrate to a setup with virtual mailboxes/users. From the wiki and comments within dovecot.conf, I see it is possible to do this piecemeal so both local and virtual users can co-exist during the transition. My question is how to keep things working as they are for existing users/domains (which will be migrated later), and use the virtual mailboxes (and thus, a different mail_location) exclusively for the new users. I understand that multiple userdbs and passdbs can be specified, and this will take care of authentication. On http://wiki.dovecot.org/VirtualUsers#homedirs it is stated that "The userdb can return the mail extra field to override the default mail_location setting. Usually you shouldn't need this." Where is this mail extra field defined? In the userdb passwd-file or somewhere within dovecot.conf? If the former, would something like this suffice (mind the wrapping): user@domain.org::5000:5000::/home/vhosts/domain.org/:/usr/sbin/nologin::mail=m aildir:/home/vhosts/%d/%n Thanks, -- Sahil Tandon <sahil(a)tandon.net>

Re: [Dovecot] how to store flags \Seen into read-only mailbox?

I was looking for workaround, and tried to use one uid for all users, and ACL plugin to give permissions like: --- owner lrwstiekxa anyone rls --- rls should mean read, lookup and write-seen. Read and lookup works, and as soon as I remove these letters I can't read mail folder. But 's' is not working, I'm getting the same: --- 7 OK Store ignored with read-only mailbox. --- in rawlogs I can not find a way for users to keep their own track of what messages have been \Seen in read-only shared folder. -- Sergey Ivanov. ----- seriv(a)parkheights.dyndns.org wrote: > This problem is apparently about changeset > http://hg.dovecot.org/dovecot-1.1/rev/eec74a6ad62e. > This change makes dovecot behaviour different from what is described > in wiki, about sharing and making private /Seen flags, > see http://wiki.dovecot.org/SharedMailboxes?highlight=(flags are > shared or private) > When I've tried to revert it, first time with my client it worked > perfectly. > But then clients were not able to open any mail folders, and imap > processes were dying. > -- > Sergey Ivanov.

[Dovecot] Dovecot 1.1.2, SIGABRT on copy mail
by Andreas M. Kirchwitz 25 Jul '08

25 Jul '08

Hi folks, with the brandnew release Dovecot 1.1.2, the daemon killed itself with signal 6 (SIGABRT) when trying to save a mail from the INBOX to another folder. The mail client is PINE 4.64. After reconnecting to the IMAP server, the mail was actually copied to the destination folder, but the original mail was still in the INBOX and not flagged as "deleted". This is the panic: Jul 25 02:13:25 linux dovecot: Panic: IMAP(user2): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Jul 25 02:13:25 linux dovecot: IMAP(user2): Raw backtrace: imap [0x80cf8e0] -> imap [0x80cf93a] -> imap [0x80cf26c] -> imap [0x809d11a] -> imap(index_mailbox_set_recent_seq+0x3e) [0x809d15e] -> imap(mbox_sync+0x105d) [0x80823fd] -> imap [0x807a454] -> imap(index_transaction_commit+0x4e) [0x809ddfe] -> imap(cmd_copy+0x35f) [0x805b26f] -> imap [0x805fd7c] -> imap [0x805fe25] -> imap [0x80605e5] -> imap(client_input+0x5e) [0x80607fe] -> imap(io_loop_handler_run+0x100) [0x80d7230] -> imap(io_loop_run+0x28) [0x80d63c8] -> imap(main+0x4a1) [0x8068321] -> /lib/libc.so.6(__libc_start_main+0xe0) [0x149390] -> imap [0x805a101] Jul 25 02:13:25 linux dovecot: child 7954 (imap) killed with signal 6 Thus, the daemon died somewhere between successfully saving a copy of the mail from INBOX to the destination folder and flagging it to be deleted in the INBOX. Just a couple of minutes later, Dovecot died again. Wanted to save a message from INBOX to another folder. But this time, the message wasn't written to the destination folder. As before, the original mail in the INBOX didn't change any flags.

[Dovecot] dovecot.conf permissions
by Dan Horák 24 Jul '08

24 Jul '08

Hi, I have a little problem with defining the right permissions for dovecot.conf. The main problem is that the password for SSL certificates is stored there and the conf file is world readable by default, which makes a security problem [1]. It is not a problem to restrict the permissions to 0600, dovecot will still work, but then deliver cannot work as it reads the conf too, but it runs under arbitrary user. So my last iteration is 0640 as permission and root:mail as ownership, but that expects that deliver is run with group = mail. For the long term solution I would prefer to move the password into a separate config file so the permissions can be properly restricted there. What are your opinions?

[Dovecot] Delivery notifications
by Brandon Keepers 24 Jul '08

24 Jul '08

I'm working on an application that is backed by Postfix 2.3.8 and Dovecot 1.0.13, configured with virtual domains, for handling messaging. I need to be able to send the notification (such as "You've received a new message on SomeAwesomeService. Click here to check it out", It's evil, I know) to a different email address, such as a mobile device. Eventually, we want to do other things like clear web page caches when a message is received, or sending IM notifications, but that's for another day. So basically, we want to notify our application whenever a new mail is received, and it can do all the magical things that it needs to do. I was hoping to get some feedback on the different approaches I'm looking at. From what I can tell, there's not a way to deliver to multiple virtual transports in postfix, so here's the options I see: * Content filter I could set up a "content filter" that just delivers the mail to the application, and then re-injects it back into postfix. This seems like more work than the other options just because I have to worry about re- injecting the message * Intercept delivery Replace the dovecot deliver command with a custom one that calls the dovecot deliver and then passes the message on to the application. I've written a little proof of concept for this and it seems to work, but just seem shady. * Sieve Dovecot supports Sieve, so I could just have a global sieve script that sends the notifications. This is definitely the solution I'm leaning towards. Are there any better options? Do you think this will have a significant impact on performance? Am I crazy? Thanks, Brandon

[Dovecot] making IMAP quicker on LAN
by Andrew Von Cid 24 Jul '08

24 Jul '08

Hi all, I keep on hitting this problem when migrating new clients from POP or local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is hosted properly in a data center. People usually complain that it's slower and although they're getting a kick ass mail setup it doesn't look good from their point of view. I'm wondering if there is anything I could do to speed it up on their LAN's. What I mean is probably a caching IMAP proxy or some sort of replication to a local Dovecot server. Is this something Dovecot can do? I'd be really grateful for any opinions on how to tackle this problem. Many thanks, Andrew.

[Dovecot] how to store flags \Seen into read-only mailbox?
by seriv＠parkheights.dyndns.org 24 Jul '08

24 Jul '08

Hi, I'm trying to use dovecot for storing mailing lists and read-only access for users. The OS is Solaris, authentication for all readers of these lists are from Ldap through PAM, and one local user "listuser" will receive all mail and store them into it's folders (Maildirs). These maildirs are readable (read-only) for all others and they are shared by setting --- mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index --- Mail became readable because in each mail folder to be shared there is dovecot-shared with mode 064, and all users included into his group. But this is the problem: how to have flag \Seen stored in read-only mailbox? As recorded by rawlog, it is ignored now: --- bash-3.00# cat 20080724-103219-10616.in 3 namespace 4 lsub "" "*" 5 list "" "INBOX" 6 list "" "Trash" 7 create "Trash" 8 select "OmniTI.FreeLotto.Ops" 9 UID fetch 1:* (FLAGS) 10 uid store 1:3 +Flags (\Seen) 11 IDLE DONE 12 close 13 logout bash-3.00# cat 20080724-103219-10616.out * OK [RAWLOG TIMESTAMP] 2008-07-24 10:32:19 * NAMESPACE (("" "."))

Hmm. I don't necessarily see that as a desirable feature because in the case that something is actually wrong with the spam tagging you want to notice it isn't working right. If you really need that, just don't set an error when it happens and do nothing, allowing the move. johannes

There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems. There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two. So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz Largest changes since v1.1.1 are: + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed

[Dovecot] Problems with deliver and account resolving
by Andreas Podgurski 24 Jul '08

24 Jul '08

Hi! I'm currently setting up my first mailsystem based on dovecot. For a far way, working with dovecot was very convenient, but after I had to integrate deliver, it became massivly painful. My components are postfix as MTA, postgresql as user database and dovecot as IMAP server. When translating the mail adresse into the account name, something goes terribly wrong (Mail adresses modified to protect against spam, think about them in correct format): dovecot: Jul 22 01:48:13 Info: auth(default-listen): master in: USER 1 Andreas.Podgurski_at_MediaGUILD.de service=deliver dovecot: Jul 22 01:48:13 Info: auth(default-listen): prefetch(Andreas.Podgurski_at_MediaGUILD.de): passdb didn't return userdb entries, trying the next userdb dovecot: Jul 22 01:48:13 Info: auth(default-listen): sql(Andreas.Podgurski_at_MediaGUILD.de): SELECT 1011 AS uid,1011 AS gid,'/var/www/jade/mail/' || admin.username AS home,admin.username AS user FROM admin,email WHERE lower(email.local_address) = lower('Andreas.Podgurski') AND email.receiver = admin.id; dovecot: Jul 22 01:48:13 Info: auth(default-listen): auth(Andreas.Podgurski_at_MediaGUILD.de): username changed Andreas.Podgurski_at_MediaGUILD.de -> SunAdmin dovecot: Jul 22 01:48:13 Info: auth(default-listen): master out: USER 1 SunAdmin uid=1011 gid=1011 home=/var/www/jade/mail/SunAdmin deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Error: mkdir(/var/www/jade/mail/Andreas.Podgurski_at_MediaGUILD.de/cur) failed: Permission denied deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Info: msgid=<20080721234813.302260(a)gmx.net>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2008-07-22 01:48:13] As you can see, the account SunAdmin has an email adresse andreas.podgurski_at_mediaguild.de assigned. The database seems to reveil the username correctly, but after that, deliver continues to use the original mail adresse, not the account name returned by the auth master. Any idea, where my solution went the wrong way? The uid/gid belong to vmail:vmail, which is used for the auth-master, as well as for running deliver and to dispatch the postfix messages. Btw., I ask myself, how dovecot can assume to use prefetch in this case, as prefetch bases upon the password query, which has to fail in this case, as there is no password. Shouldn't it not even try to use the prefetch values there...? Thanks in advance, Andreas Podgurski -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

[Dovecot] cosmetic: "userdb" checkpassword
by Heiko Schlichting 24 Jul '08

24 Jul '08

Hi, $ dovecot --build-options Build options: ioloop=epoll notify=inotify Mail storages: maildir SQL drivers: Passdb: checkpassword Userdb: checkpassword prefetch Isn't "checkpassword" misplaced in the userdb list? For me it seems that USERDB_CHECKPASSWORD is only used in configure and for printing the build-options. Additionally checkpassword protocol does not makes any sense for a userdb. It could be used only for passdb plus prefetching userdb. Therefore I suggest to remove USERDB_CHECKPASSWORD to make this more obvious althought this is only cosmetic.

[Dovecot] Problem authenticating iPod Touch
by Mark Leisher 24 Jul '08

24 Jul '08

Given the (slightly edited) config info below, iPod Touch users are unable to connect, leaving the following message in the log file: dovecot: Jul 23 10:00:40 Info: imap-login: Disconnected (auth failed, 0 attempts): rip=1.2.3.4, lip=5.6.7.8, TLS handshaking: Disconnected Even with maximum logging on, no other error messages seem related to this problem. Am I missing something simple I didn't catch in the list archives? Or is it more likely a problem on the iPod side? The iPods connect to our non-dovecot IMAP servers with no problem. # 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/imap-dovecot listen: *:143 ssl_listen *:943 ssl_cert_file: /etc/ssl/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot login_greeting: IMAP ready. login_processes_count: 10 login_max_processes_count: 30 mail_location: maildir:~/Maildir mail_nfs_index: yes auth default: passdb: driver: passwd userdb: driver: passwd -- Mark Leisher

[Dovecot] \HasNoChildren versus \Noinferiors in ACL plugin and no CREATE permission
by Heiko Schlichting 23 Jul '08

23 Jul '08

Hi, using ACL plugin with dovecot 1.1.1 I expected that a Maildir was listed as * LIST (\NoInferiors) "/" "Foldername" if "create" (k) permission is not set in ACLs and there doesn't exists any subfolders. But to my surprise, dovecot gives the following output: * LIST (\HasNoChildren) "/" "Foldername" Therefore the client (here: SquirrelMail) does not know about the inability to create subfolders and offers "Foldername" in the selection for the parent folder. If there are exists already subfolders of "Foldername", dovecot has to use \HasChildren and not \NoInferiors. But in other cases \NoInferiors should be the correct answer and not \HasNoChildren. Or am I totally wrong?

[Dovecot] Mailbox_module_context question
by Daniel Brosseau 23 Jul '08

23 Jul '08

Hi, I am new to the dovecot source and would like to know why the mailbox_module_context has a pointer to the mail_storage_module_register and not to a mailbox_module_register. From what I have understood, if a context is first added to the mailbox.module_contexts array using the mail_storage_module_register and then a context is added to the mail_storage.module_contexts and then a third context is again added to the mailbox.module_contexts the mail_storage_module_register.id will be 3 and the second element in the mailbox.module_context will be unused and the first and third elements of the mail_storage.module_contexts are unused. There might be something I am not understanding here so please forgive me if my question has an obvious answer. Daniel

Guys, We have a very large maildir for email auditing purposes. It's currently at 600 GB and continues to grow. Can dovecot handle this with squat indexing, or am I out of my mind? Thanks! John

[Dovecot] 1.1.1-1 gotcha with Fedora Rawhide package
by Kenneth Porter 23 Jul '08

23 Jul '08

I just installed the Rawhide package on my CentOS 5 system. The one item that bit me is that the config file defaults to using interface "[::]" so it only listens on IPv6. (This is from a patch in the package that changes the upstream default of "*", so it only affects those using the Fedora package.) For those wanting to track the issue, here's the Bugzilla: <https://bugzilla.redhat.com/show_bug.cgi?id=453054> I rebuilt the package from the source RPM, to make sure it was "tuned" to the C5 distro. I got the source RPM here, from the Portland State mirror: <http://mirrors.cat.pdx.edu/fedora/linux/development/source/SRPMS/dovecot-1.…> Here's a full list of Rawhide mirrors: <http://mirrors.fedoraproject.org/publiclist/Fedora/development/> If you'd like to see all Red Hat bugs associated with dovecot, here's a suitable query: <https://bugzilla.redhat.com/buglist.cgi?component=dovecot>

[Dovecot] 1.0.14 -> 1.1.1: dovecot-uidlist errors
by Amitai Schlair 23 Jul '08

23 Jul '08

[Dovecot] Namespaces
by Jason Frisvold 22 Jul '08

22 Jul '08

Hi all, I'm working to convert from a bincIMAP setup to a Dovecot setup. I've tried messing around with namespaces to make the conversion transparent, but I'm getting nowhere. Are namespaces necessary? Or can I proceed by recursively renaming the folders on the server? A transparent solution would be wonderful, but I can't get it to work for me.. Any help would be appreciated. Thanks! -- Jason 'XenoPhage' Frisvold XenoPhage0(a)gmail.com http://blog.godshell.com

[Dovecot] Sieve plugin should recompile when symbolic link changes [patch]
by Frank Behrens 22 Jul '08

22 Jul '08

The sieve plugin compares the modification dates of sieve source and compiled script and compiles the script only if necessary. When the managesieve extension is used, it creates a symbolic link for the script. In order to switch between scripts managesieve changes the link only. Therefore the sieve plugin should include the modification date of an symlink in its decision about compilation. The attached patch adds this functionality.

[Dovecot] ACL in sub-folders (take two)
by Imobach González Sosa 22 Jul '08

22 Jul '08

Hi all, I've read this not on the v1.1.2 release candidate announce: > If you haven't received an answer to your question, resend it. So, I've sent this message some days ago and I've got no answer (that's fine, no problem). So, I'm posting my question again: I've set up some shared folders and I'm controlling the access to them with the ACL plugin. As far as I know, ACL rules are not applied to sub-folders, right? So, when a user adds a new sub-folder, I need to add a dovecot-acl file granting read permissions to others users, right? Does exists any way to implement it using some dovecot feature? Or must I find my way? Just to be sure :) Thank you in advance. -- Imobach González Sosa Banot.net http://www.banot.net/

Hello: CentOS 5.2 Postfix 2.3.3 (part of CentOS install) Dovecot 1.0.7 (part of CentOS install) Dovecot 1.1.1 (Updated from www.atrpms.net) Postfix & Dovecot are working fine. While reading "Dovecot LDA with Postfix" document at http://wiki.dovecot.org/LDA/Postfix , I read the following statement: --------------------- Dovecot LDA with Postfix System users If you wish you use deliver for all system users on a single domain mail host you can do it by editing mailbox_command parameter in /etc/postfix/main.cf (postconf(5)): mailbox_command = /usr/local/libexec/dovecot/deliver # or mailbox_command = /usr/libexec/dovecot/deliver # or mailbox_command = /usr/lib/dovecot/deliver # or wherever it was installed in your system. Then run postfix reload and that is it. --------------------- Here is the problem; I do not find location of ".../dovecot/deliver" anywhere on the system! 1. Did I do any mistake during the Postfix and/or Dovecot install/configuration? 2. Next, I plan to install "Dovecot-Sieve". Do I need the "mailbox_command" for "Dovecot-Sieve" to work? Kirti

[Dovecot] A couple of dovecot issues I've noted recently...
by Dan Price 21 Jul '08

21 Jul '08

Timo et al., I haven't been reading the list in a while, but wanted to report back that we've transitioned to dovecot 1.0.15 and things look to be working very nicely. The platform is Solaris "Nevada" running on x86. I have been saving up a couple of issues to bring to your attention. On our server, we gather all core files, and so we get a good taste of the different things which are causing crashes. One problem which we see on an occasional basis is a crash in which the internal fatal error handling code goes horribly wrong. Here is an example. The complete stack trace is hugely long-- it appears that we recurse until we run totally out of stack. In gdb this looks like repeated calls like this: ... #14507 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b95d8 "\020") at failures.c:410 #14508 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14509 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14510 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14511 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14512 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14513 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14514 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b96d8 "\020") at failures.c:383 #14515 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b96d8 "\020") at failures.c:410 #14516 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14517 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14518 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14519 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14520 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14521 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14522 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b97d8 "\020") at failures.c:383 #14523 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b97d8 "\020") at failures.c:410 #14524 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14525 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14526 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14527 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14528 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14529 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14530 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b98d8 "\020") at failures.c:383 #14531 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b98d8 "\020") at failures.c:410 #14532 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14533 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14534 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14535 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14536 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14537 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14538 0x080b21f3 in internal_handler (log_type=70 'F', ...

It seems like once we fall into i_internal_fatal_handler(), dovecot should really try hard to avoid further dynamic memory allocation, as heap corruption seems to make that a bit of a disaster. As for the crash in mbox_list_next, we see that one too with some frequency. A final problem, and this one affects me personally, is that we see some errors like this: dovecot: Jul 09 11:52:10 Error: IMAP(dp): FETCH for mailbox mail/tmp-inbox UID 92086 got too little data: 6054 vs 6057 dovecot: Jul 09 11:52:10 Info: IMAP(dp): Disconnected: Disconnected This is frustrating because I wind up with "poisonous" messages in my inbox which cause dovecot to disconnect me when I try to read them. Across all of our users, we see this happen about 1000 times per month. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Deliver mail as 'read'?
by Peter Collinson 21 Jul '08

21 Jul '08

I'd like to be able to deliver certain mail as 'read' from procmail. My procmail rules call deliver with -m to directly to inject filtered mail to maildir based directories. I like to keep copies of mail I've sent by cc'ing it to myself and using procmail to filter and store copies in the appropriate directory. I cannot seem to find a way of delivering cc'd mail from me to me as 'read'. I'm running dovecot-1.0.7-2.el5 on a CentOS 5 distribution. Any hints on how I may achieve this are welcomed. Happy to upgrade if needs be. Thanks. _____________________________________________ Peter Collinson

[Dovecot] The case of the disappearing INBOX's - upgrade to 1.1.1 from 1.0.7 and based on Email client type
by Jack Stewart 21 Jul '08

21 Jul '08

Hi, I apologize if this has already been answered. I looked for an identical message but had no luck. I'm also not convinced this is a bug or if it is a bug that I want it fixed. The problem gives me a great reason to change our configuration to something more modern. Here is the situation. Our 1.0.7 configuration has the following, and only, namespace definition. namespace private { separator = . prefix = Mail. inbox = yes } This configuration was implemented years ago in order to simplify the upgrade from mail spool to IMAP for people who use mutt and pine. The interesting part is that after upgrading to 1.1.1, the INBOX would disappear from Thunderbird after clicking on a different folder. Now mutt worked just fine, which was even worse. Changing the configuration so that the INBOX appeared on Thunderbird caused the INBOX to disappear (or be unreachable) on mutt. After trying multiple configurations with every permutation, and making several wall dents with my forehead, I finally found this configuration. namespace private { separator = . prefix = INBOX. inbox = yes hidden = no list = yes } namespace private { separator = . prefix = Mail. hidden = yes list = no } For the most part, this works just fine. INBOX appears for every client I've tested and the migration is largely transparent. The only time I found issues is when the Trash, Sent, etc. folders were manually specified in a GUI client such as Thunderbird. Still the real question remains. Is this supposed to happen? If so, what are some of the reasons? Naturally my management would prefer that the original configuration works the same so that things are transparent. Personally, the second configuration feels better to me especially on a going forward basis. Thanks in advance for any answers or hints. ---Jack -- Jack Stewart jstewart(a)caltech.edu http://www.imss.caltech.edu

Re: [Dovecot] litte problems upgrade from 1.0.x to 1.1.1

I can recreate it with dovecot 1.1.1 running on my machine. I create completly new mbox, write to it and when i view mbox in console i see just this mail. After deleting (pop3) this mail with our webmailer or OutLook Express etc. I see this internal message with current date. I do not belive in Clients that put internal mesages by pop3-protocol, but what should it be else? pop/imapserver is dovecot 1.1.1 And why this case just happens by updateing from 1.0.x to 1.1.1 and not during further updates from 1.0.x to 1.0.x+1 ? If you say this is not dovecot related i have to accept this but i am a little bit doubtful... Unfortunately i have now a more annoying error in imap processing. Sometimes it happens that dovecot seems to be out of sync.

[Dovecot] recursive acl problem
by Robert Schetterer 21 Jul '08

21 Jul '08

Hi, i ve got a problem with recursive acl, using not a vfile global backend. ( no default acl) In my understanding every folder(directory) needs a seperate dovecot-acl files with permissions. This works fine, but my tests showed using a shared namespace like i.e. namespace shared { separator = / prefix = "users/%d/" location = dbox:/usr/local/virtual/%d/ inbox = no list = yes subscriptions = yes hidden = no } and have dovecot-acl in usr/local/virtual/%d/ with authenticated l which means lookup, leads that all folders and subfolders of /usr/local/virtual/%d/%u/ are imap browseable, which means its recursive somekind. ( people will not like seeing folder names of their mailboxes until they dont gave permissions explicit to others) In my meaning this shouldnt be so only names of ( names of directories) at /usr/local/virtual/%d/%u/ should be shown , subfolders in them should only be imap browseable if there is another dovecot-acl in them which permits lookup i may fail here , anyone which has some enlightment for me outside? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Mails "invisible" (index corrupted?)
by Patrick Nagel 21 Jul '08

21 Jul '08

Hi, I got a complaint from a user today, that a few mails "disappeared" from her Inbox, both when accessing via IMAP with Thunderbird and in the IMAP Webmail client (RoundCube Webmail, caching deactivated). Searching (in Subject or From header) within the Inbox turned up the missing messages though. After checking all relevant client settings (filter rules etc.), restarting Thunderbird multiple times, etc., I tried deleting her dovecot.index.cache file, restarting Thunderbird again, but that didn't change anything. Only after deleting dovecot.index.*, everything went back to normal. I can't find anything useful in the log. Setup: x86, CentOS Linux, dovecot 1.1.1 (current stable binary from ATrpms), maildir storage, mail_debug is turned on Any hints on what could have caused this? Where to look? I backed up dovecot.index, dovecot.index.cache and dovecot.index.log before I deleted them, but they probably contain sensitive information, so I won't post them to the list.
