[Dovecot] Funky quota things
by Guy 27 Jul '09

27 Jul '09

Hi guys, I already use Dovecot for imap/pop3 with some simple quota options. I'm starting to look at the switch from maildrop to dovecot lda and I'm wondering whether it's possible to do our unusual quota management with the quota plugin. We have the users total quota in MySQL along with a number of grace days (counts up to 7). The amount of space used is stored in maildirsize in the users maildir. What we currently some bits of voodoo which allow the user to go up to 200% of their quota. When they go over 100% they start receiving warnings and their grace days start counting down. If the account is still using over 100% of quota after the 7 days then the 100% quota is enforced so no new mail will be accepted. So is something like this "burst" quota possible in the Dovecot plugin? Thanks Guy -- Don't just do something...sit there!

Hello, we found dovecot down on one of our servers, with this error in the log: dovecot: 2009-07-14 04:05:04 Warning: SIGHUP received - reloading configuration dovecot: 2009-07-14 04:05:04 Error: Temporary failure in creating login processes, slowing down for now dovecot: 2009-07-14 04:05:04 Fatal: listen(143) failed: Interrupted system call we can reproduce this error with this tight loop: while date ; do kill -HUP $(cat /var/run/dovecot/master.pid) ; sleep 15s ; done after a while dovecot dies with the above error message. We are using # dovecot --version 1.0.15 in particular, Debian package with version "1:1.0.15-2.3" . This started since yesterday, when we upgraded to the latest Debian Lenny point release. The situation is rather problematic, and we'd like to here from you if there something we can do to fix it; if there's something you'd like us to do, just ask :) Thanks in advance, Sandro

[Dovecot] Sylpheed-claws and virtual mailboxes
by Thomas Berker 27 Jul '09

27 Jul '09

Hi! Has someone encountered the following problem? What am I doing wrong or does someone know a workaround? Dovecot 1.2.1 on Debian unstable, two namespaces: namespace private { prefix = location = maildir:~/res/Maildir:LAYOUT=fs inbox = yes list = yes } namespace private { prefix = gtd/ separator = / list = yes location = virtual:~/res/Maildir/gtd:LAYOUT=fs:INBOX=~/res/Maildir/gtd } The problem: cur, tmp, new maildir folders get created within the folder gtd when it is opened by Sylpheed-claws (3.7.1). Subfolders in gtd holding the dovecot-virtual files are not recognised as mail folders at all, they show up but do nothing. Other clients (I have tested thunderbird, evolution) work as expected: they show the folder gtd and the sub-folders perform searches. Thanks in advance, tb

[Dovecot] Problems with ioloop on MacOS

[Dovecot] [BUG] Incorrect maildir quota value after maildirsize creation
by Adam Osuchowski 27 Jul '09

I found a problem with maildir++ quota. When dovecot creates maildirsize file, it counts quota wrong. This is, how I reproduce a situation on version 1.2.0: First, I remove maildirsize file: # cd /var/mail/test # rm -f maildirsize # ls -la total 32 drwx--S--- 5 mbox mbox 4096 Jul 12 20:45 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 9 20:45 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:45 dovecot.index.cache -rw------- 1 mbox mbox 284 Jul 12 20:45 dovecot.index.log drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 tmp I have 8 emails which take 14183471 bytes together: # find cur new -type f | wc -l 8 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14183471 Now, I connect to dovecot via POP3 and delete exactly _one_ email which takes 969 bytes. After that, maildirsize file has been created: # ls -la total 48 drwx--S--- 5 mbox mbox 4096 Jul 12 20:50 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 12 20:50 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:50 dovecot.index.cache -rw------- 1 mbox mbox 532 Jul 12 20:50 dovecot.index.log -rw------- 1 mbox mbox 28 Jul 12 20:50 maildirsize drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 tmp # cat maildirsize 5242880S 14182502 7 -969 -1 So, maildirsize says, that there should be 7-1=6 emails which should take 14182502-969=14181533 bytes together. In fact, there are 7 emails (I delete only one of eight emails) which take 14182502 bytes together (deleted email taked 969 bytes): # find cur new -type f | wc -l 7 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14182502 I figured, that dovecot after physically file removal, calls function maildir_quota_update(), which calls maildirquota_refresh() first (which in turn recalculate quota with new values), and then calls maildirsize_update(), which additionally and incorrectly decreases quota value. Regards, Adam.

[Dovecot] [PATCH] include parameters can handle globbing
by Thomas GUTHMANN 27 Jul '09

27 Jul '09

Hey guys, This patch will allow you to include different configuration files in the main dovecot.conf by using globbing [1] (like Apache for instance). !include = conf.d/*.conf !include_try = /etc/dovecot/extra* So with this you can split the dovecot.conf in different smaller configuration files. It's more the debian way to do that. But it's very handy if you have to generate dynamically parts of dovecot.conf based on a centralized main configuration (imagine you have 10 servers and you want to change the default quota for instance, do a script which update that based on the data contained in SQL/LDAP/XML/whatever). I designed this for my personal use with dovecot 1.2.1. It does the job. But I warn you :) My code may hurt your eyes. If so either close them or improve/fix my code or ... "Hare Krishna" [2] :) The include features has been done and almost kept hidden by Timo :) I've just add the globbing feature to !include and !include_try. The patch will modify - src/lib-settings/settings.c - dovecot-example.conf $ cd dovecot-1.2.1 $ patch -p1 < includepatch.diff It has been test with GNU/Linux Debian dunno if it compiles on FreeBSD/AIX/MacOSX but everything is POSIX compliant so... it should :) Cheers, Thomas [1]: Thanks Aria for the tip about the glob() function. It's cleaner. [2]: Rumor has it that Hare Krishna means hire a consultant in Hindi.

[Dovecot] Newbie: unable to access mailbox more than once
by Matt Petoe 27 Jul '09

27 Jul '09

Hello, I'm using dovecot as a mail relay so that I can back up my providers IMAP mail locally. I'm impressed how easy this was to set up, but I'm having a quirk that I would like help with, if possible. There are many weak links in my set-up chain, if you will, but I think I've narrowed the problem. I'll describe my set-up anyway. I'm running dovecot 1.1.4 on ubuntu 8.10. I have a shared NAS drive running a NFS server. I have chosen to store the .indexes and .control directories on the NAS also, since I want a set-up that will remain backed up and easily replicated if I (accidentally) erase the ubuntu install in the future. I'm using imapsync to copy messages from my email provider. It works once only, and subsequent attempts seem to hang when accessing any local dovecot mailbox folders that were changed last time. I have succeeded in using Thunderbird to access the dovecot mailboxes once. I know the paths are being found, because I can 'list' mailboxes when I telnet locally: b list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "indexes" * LIST (\HasNoChildren) "." "control" * LIST (\HasNoChildren) "." "Junk" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "INBOX" * LIST (\HasNoChildren) "." "Trash-1000" b OK List completed. However, a 'select' command will only work for empty folders (such as .Trash). If I try to select a full folder such as ".Sent" then the process just hangs. The logs don't mention anything interesting, even though I have enabled debug_on and auth_debug. However, I attached a trace to the 'imap' process and got something interesting. I think maybe the lock process is failing for some reason? Here's a snip of the failure when selecting the .Sent folder: 12:00:21.190011 gettimeofday({1248141621, 190099}, NULL) = 0 12:00:21.190503 read(0, "f select Sent\r\n", 4034) = 15 12:00:21.190906 stat64("/mnt/Mail/.Sent/tmp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 12:00:21.241561 stat64("/mnt/Mail/.indexes/.Sent", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 12:00:21.248325 stat64("/mnt/Mail/.Sent/dovecot-shared", 0xbf86c6c8) = -1 ENOENT (No such file or directory) 12:00:21.248847 time(NULL) = 1248141621 12:00:21.249060 open("/mnt/Mail/.indexes/.Sent/dovecot.index.log", O_RDWR|O_LARGEFILE) = 7 12:00:21.286953 fstat64(7, {st_mode=S_IFREG|0600, st_size=26472, ...}) = 0 12:00:21.287423 pread64(7, "\1\0\30\0\264:dJ\4\0\0\0\3\0\0\0\\\200\0\0\374?dJ", 24, 0) = 24 12:00:21.287696 stat64("/mnt/Mail/.indexes/.Sent/dovecot.index.log.2", 0xbf86c5ac) = -1 ENOENT (No such file or directory) 12:00:21.288070 open("/mnt/Mail/.indexes/.Sent/dovecot.index.log.2", O_RDWR|O_LARGEFILE) = -1 ENOENT (No such file or directory) 12:00:21.288614 open("/mnt/Mail/.indexes/.Sent/dovecot.index", O_RDWR|O_LARGEFILE) = 9 12:00:21.296814 alarm(60) = 0 12:00:21.297181 fcntl64(9, F_SETLKW64, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0} I have set the locks to dotlock_try followed by fcntl.

The summary, I guess, is that I can't access mailbox folders with emails inside. I'm very new at all this, and only got this far from the excellent wiki. But now I'm stumped. Thanks heaps, Matt P

[Dovecot] lazy expunge - how to unset deleted imap flag
by Colo Colo 27 Jul '09

27 Jul '09

Hello, I am using dovecot 1.1.13 in debian lenny with exim4 and I have Outlook 2007 clients. I have configured lazy expunge plugin. User marks messages in INBOX for deletion then click "delete messages from server" then the messages are moved to .EXPUNGED folder which is correct but they are still marked with IMAP deleted flag which is bad cause when user marks another messages in INBOX for deletion and click again on "delete messages from server" the messages which were in .EXPUNGE are gone forever. Is there any possibility to change this behavior i.e. instead from: move messages tagged for deletion to .EXPUNGE folder to: move messages tagged for deletion to .EXPUNGE folder and UNSET deleted flag ? Thanx

[Dovecot] Public mailboxes with ACL in 1.2
by sstrickroth＠trg-oha.de 27 Jul '09

27 Jul '09

Hi, I'm new to Dovecot 1.2 and I'd like to replace uw-imap. I'd like to have the following setup: - Personal mailboxes using maildir for all users (no problem) - Public mailboxes for certain people who are in special groups from /etc/group localed in /var/spool/public as a maildir with subfolders for each group (which should only be visible for that group and also secured by filesystem group permissions). At best those folders should be visible for the users below "shared"-folder or parallel to the inbox. The public mailboxes should be secured by custom ACLs (so that not all ppl. can create new folders and so on). How can I make Dovecot authenticate against pam and use groups in /etc/group? When I activate the ACL plugin all public or shared mailboxes are hidden. How can I avoid this for the public mailboxes? Thanks in advance. Sven

[Dovecot] Search fails on underscores in quoted-printable
by Andreas M. Kirchwitz 27 Jul '09

27 Jul '09

Hi folks, currently I'm running Dovecot 1.2.1. Compiled from source on Fedora 10 Linux 32 Bit (all patches). Clients are Pine 4.64, Thunderbird 2.0.0.22 and Mutt 1.5.20 (using "=b" for server-side searching). When a message contains the text "under_score" and I let the server search for it, Dovecot does not find it in messages with a Content-Transfer-Encoding of "quoted-printable". It works perfectly well with messages without Content-Transfer-Encoding. If I replace the underscore with a space (search for "under score"), it magically matches on "under_score" (no space but underscore). Looks like something goes wrong with the encoding/decoding of quoted-printable (sorry, haven't tried with base64). Example: Dovecot does not find "under_score" | Date: Fri, 24 Jul 2009 02:08:45 +0200 | From: "Andreas M. Kirchwitz" <amk(a)krell.zikzak.de> | To: "Andreas M. Kirchwitz" <amk(a)krell.zikzak.de> | MIME-Version: 1.0 | Content-Type: text/plain; charset=iso-8859-1 | Content-Disposition: inline | Content-Transfer-Encoding: quoted-printable | | test for under_score and dovecot search (=E4=F6=FC=DF) Example: Dovecot find's "under_score" without problems | Date: Fri, 24 Jul 2009 02:10:26 +0200 | From: "Andreas M. Kirchwitz" <amk(a)krell.zikzak.de> | To: "Andreas M. Kirchwitz" <amk(a)krell.zikzak.de> | MIME-Version: 1.0 | Content-Type: text/plain; charset=us-ascii | Content-Disposition: inline | | test for under_score and dovecot search (1234) The problem is not new to Dovecot 1.2.1 but exists in the 1.1 series as well. Greetings, Andreas

Hello, My "exim" is doing the deliveries, "dovecot" handles POP/IMAP.

Therefor there must be a short period of time where no maildirsize exists. Can this really happen? If yes, could this behaviour be changed? Kind regards, Frank Elsner

[Dovecot] Dovecot 1.2, quota and LDAP
by Stian Jordet 26 Jul '09

26 Jul '09

Hi! I'm in the progress of upgrading from Dovecot 1.0.15 to 1.2.1. This has gone pretty smooth. I just have one question to check wether I have understood the documentation right. I have both system users and virtual users. That's easy to do when using LDAP for userdb. The system users use filesystems quota, the virtual users use maildir quota. I achieved this using the following in LDAP: "fs:" (for system users, obviously) and "maildir:storage=2048000" for virtual users. This has worked fine for years. But after reading the documentation, it seems I now have to use two ldap-fields to achieve the same thing? One "quota" and one "quota_rule"? Is this correct? It's of course not impossible, but it's kinda a hassle to hand craft a new schema, deploy, and update all the user's entries. If my users didn't have two kind of quotas, it would be easy, but with two quota methods, I don't see any other way than to use two ldap-fields. Which I hope I don't have to :) Thanks. Regards, Stian

[Dovecot] configure performs checks for not needed sasl headers
by Pascal Volk 26 Jul '09

Hi, I'm always surprised when I see output from configure like checking for really_not_needed.h... no The configure script is always 'checking sasl.h usability' even when the --without-ldap option was specified. The attached patch checks the presence of sasl.h / sasl/sasl.h only when using the --with-ldap option && all required LDAP headers and libs are available.

[Dovecot] Several errors
by FraNL 25 Jul '09

25 Jul '09

Hi, Running OS: CentOS 5.3 (2.6.18-128.2.1.el5) 1. My Linux distribution comes with Dovecot 1.0.7. After trying to make it running, I encoutnered many problems. So I decided to upgrade to 1.2.1. When running dovecot -r from CLI, it returns with version 1.2.1. But at the top of the log file it says: Info: Dovecot v1.0.7 starting up So I am not sure which version I am running. That's the first problem. The other two problems I am having were also actual before updating to 1.2.1: 2. Every minute, the following lines (except for the timestamps, which are different, ofcourse) are being added to my log file: dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: child 3712 (login) returned error 89 dovecot: Jul 24 23:54:24 Error: child 3713 (login) returned error 89 dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: child 3714 (login) returned error 89 3.

[Dovecot] Are host names a secret?
by Timo Sirainen 24 Jul '09

24 Jul '09

Some time ago I added the ability for IMAP clients to fetch messages' GUIDs using FETCH X-GUID command. Because of a bug it wasn't working in 1.2.0 or 1.2.1, but I've fixed it now. But now I'm starting to wonder: With Maildirs the GUIDs are the maildir base filenames, which contain host names. Is it a bad idea to expose them to users?

[Dovecot] Maildir from offlineimap, INBOX folder created
by Ng Oon-Ee 24 Jul '09

24 Jul '09

Hi, I'm using dovecot to serve up a Maildir created/served by offlineimap. The layout is typical (as far as I know) of maildirs, with the root folder having cur, tmp, new, and subfolders being a folder within the root folder. Since I'd previously used Evolution to access this maildir, my subfolders were actual subfolders (separator /). Anyway, it all works spiffingly well, except that I can't see my inbox at all. What happens is that attempting to subscribe to Inbox will create an INBOX folder in the root folder, which is (of course) empty, so I see an empty folder. For completeness, my dovecot -n... # 1.1.17: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-ARCH x86_64 ext3 protocols: imap listen: localhost ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: maildir:/home/data/Profiles/OfflineIMAP/root:LAYOUT=fs auth default: passdb: driver: pam userdb: driver: passwd Thanks for the help.

[Dovecot] Problem with sieve scripts including sieve scripts
by Mauricio Tavares 23 Jul '09

23 Jul '09

I have the following global cmusieve scripts defined in /etc/dovecot/sieve, which is owned by the user deliver is run (virtual) as defined in the lda session of dovecot.conf: global-spam.script ====================================== require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Level" "********************" { fileinto "Spam"; # Stop here so that we do not reply on spam stop; } elsif header :contains "X-Spam-Flag" "Yes" { fileinto "Spam"; stop; } global-default.script ==================================== require ["include"]; include :global "global-spam.script"; i.e. all the default script does is call the spam script. I have created the compiled versions using sievec, making sure they are still owned by virtual: mail sieve # ls global-default.script global-spam.script global-vacation.script global-default.scriptc global-spam.scriptc global-vacation.scriptc mail sieve # In the plugins session of dovecot.conf I have defined the path for global scripts (so I can do the include :global thingie) and the path for the default script (just in case user does not have a custom script in the mail directory): plugin { sieve_global_dir = /etc/dovecot/sieve/ global_script_path = /etc/dovecot/sieve/global-default.script } So I send me some certifiable spam from my collection of test spam. This is what I got from the log: Jul 22 14:49:01 mail MailScanner[15047]: New Batch: Scanning 1 messages, 3206 bytes Jul 22 14:49:01 mail MailScanner[15047]: SpamAssassin cache hit for message C04F79F002F.784A8 Jul 22 14:49:01 mail MailScanner[15047]: Spam Checks: Found 1 spam messages Jul 22 14:49:02 mail MailScanner[15047]: Virus and Content Scanning: Starting Jul 22 14:49:02 mail MailScanner[15047]: Requeue: C04F79F002F.784A8 to 304C09F0012 Jul 22 14:49:02 mail postfix/qmgr[14869]: 304C09F0012: from=<raubvogel(a)gmail.com>, size=2518, nrcpt=1 (queue active) Jul 22 14:49:02 mail MailScanner[15047]: Uninfected: Delivered 1 messages Jul 22 14:49:02 mail deliver(raub(a)domain.com): Loading modules from directory: /usr/lib/dovecot/lda Jul 22 14:49:02 mail deliver(raub(a)domain.com): Module loaded: /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so Jul 22 14:49:02 mail dovecot: auth(default): master in: USER 1 raub(a)domain.com service=deliver Jul 22 14:49:02 mail dovecot: auth(default): master out: USER 1 raub(a)domain.com uid=1500 gid=1500 home=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: raub(a)domain.com Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: uid=1500 Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: gid=1500 Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: home=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): maildir: data=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): maildir++: root=/var/spool/vmail/domain.com/raub, index=, control=, inbox=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: /var/spool/vmail/domain.com/raub/.dovecot.sieve doesn't exist Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: Using sieve path: /etc/dovecot/sieve/global-default.script Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: Executing script /etc/dovecot/sieve/global-default.scriptc Jul 22 14:49:02 mail deliver(raub(a)domain.com): msgid=<000d01ca078a$d13122a0$6400a8c0@chameleonsh>: saved mail to INBOX Jul 22 14:49:02 mail postfix/pipe[15137]: 304C09F0012: to=<raub(a)domain.com>, relay=dovecot, delay=3.4, delays=3.3/0/0/0.1, dsn=2.0.0, status=sent (delivered via dovecot service) From what I gathered, mailscanner saw it was spam and tagged it.

Hi, I'm using version 1.2.1 with acl. How do I use acl_shared_dict? Especially with file:-dictionary. What's the layout of that file? Is it possible that the file is ignored with the current version? If the file doesn't exist or isn't readable, I don' get any error message. Best regards, Sven

[Dovecot] Released Sieve v0.1.9 for Dovecot v1.2.1
by Stephan Bosch 23 Jul '09

23 Jul '09

Hello Dovecot users, Relatively many bugs and problems were reported recently in a short period of time. Apparently, now that Dovecot v1.2 is finally stable, the new Sieve plugin is also starting to get used much more. No known bugs remain. Let's hope I didn't spawn any new ones. Apart from the bugfixes I made the deprecated notify plugin implementation compatible with CMUSieve. You can use it, but keep in mind that the (rather stupid) denotify command is not (yet) implemented and that the $text$ substitution does not work (yes, there is a world of differences compared to enotify). Changelog Sieve v0.1.9: * Removed the unfinished sieve-filter tool from the default build. It is now only built when the --with-unfinished-features switch is supplied during configure. + Started building support for the ereject version of the reject action, which has a preference to use an SMTP/LMTP protocol error in stead of a bounce message. This is to be used to make the Sieve plugin honour Deliver's -e parameter. This is not yet finished and not built by default. + Improved 'Permission denied' error messages just like Dovecot does, precisely specifying what permission is missing to access or create a file. + Added additional headers to the list of allowed headers for the address test. The restrictive nature of the address test is not always appropriate. Still thinking of a better, less restrictive implementation. + Made the deprecated notify extension compatible with the old CMUSieve plugin. However, the denotify command and the $text$ substitution are not yet supported. + Made the discard action log a message to avoid confusion about disappearing messages. - Fixed behavior of fileinto when delivering into a namespace prefix. It now uses silent delivery into INBOX as fallback. - Fixed logging of folder namespace prefix upon delivery into a prefixed namespace. Formerly it only logged the bare folder name. - Fixed a potential segfault in the argument validation. It didn't surface because no command could have a :tag followed by an associated parameter as last argument. - Fixed segfault bug occuring in envelope test when performed on null (<>) envelope path. The fix involves a rather large restructuring of the code to make sure envelope addresses are properly handled everywhere (bug reported by Nikita Koshikov) - Envelope: fixed bug in application of address parts; failure to obtain the part would cause inappropriate match success (bug reported by Ron Lee) - Fixed extension conflict checks during validation. It could sometimes produce useless errormessages. This is currently only used by the deprecated extensions. - Forgot to remove old explicit storage library dependency (patch by Arkadiusz Miskiewicz). - Fixed compiler warnings on certain platforms regarding the use fwrite for outgoing message construction -- The releases are available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz.sig -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Compiling Dovecot
by Jason Silkey 23 Jul '09

23 Jul '09

I'm attempting to compile Dovecot 1.2.1 from source with support for ManageSieve, with little success. ./configure seems to complete successfully, but make fails with the message: make: *** No targets. Stop. I checked the Makefile, and it's empty. I run into the same problem no matter the configure options, with or without the managesieve patch applied, and even with earlier versions (I also tried 1.2.0 and 1.1.17 just to see if it would work, but no go). I've had no problems compiling other software, so I'm at a bit of a loss here. Any thoughts?

[Dovecot] PAM_USER falsely assumed immutable
by Aaron Richton 23 Jul '09

23 Jul '09

In 1.2.1 there's: passdb-pam.c:230 status = pam_get_item(pamh, PAM_USER, &item); passdb-pam.c:237 auth_request_set_field(request, "user", item, NULL); so "item" is PAM_USER, which is then checked by auth_request_set_field: 1022 if (strcmp(request->user, value) != 0) { 1023 auth_request_log_debug(request, "auth", 1024 "username changed %s -> %s", 1025 request->user, value); that it hasn't changed. You're not allowed to assume that PAM_USER doesn't change. See, for example, http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/adg-security-user-i… to say nothing of the fact that Rutgers has PAM modules that do exactly that (change PAM_USER). This check needs to be relaxed (or, perhaps if you want a config directive for DontComplyWithThePAMSpec = true, you can have a tunable). Can this be as simple as ditching the call to auth_request_set_field, or is there concern over interactions between PAM and other auth features?

[Dovecot] Defunct processes w/ v1.2.1
by Chris O'Regan 22 Jul '09

22 Jul '09

I have limited information at the moment (currently distracted by other projects) but I'm hoping that someone has already found and solved this problem. I have a v1.2.1 installed on my development box waiting for me to tinker with the configuration. On several occasions, I have noticed that all the dovecot processes are listed as "defunct". I don't recall seeing anything significant in the logs the last time I checked. The system is not under any load. Has anyone else encountered this before? If not, I will dig deeper. BTW, ignore the fd limit warning below; limits are set in the init script. # /local/bin/dovecot -n # 1.2.1: /local/pkg/dovecot-1.2.1/root/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 10240).

[Dovecot] virtual plugin question
by Nikita Koshikov 22 Jul '09

22 Jul '09

Hello list, After enabling virtual plugin in dovecot config, I got imap segmentation faults from time to time. I can't say what event trigs this behavior, but in logs I see: Jul 22 13:55:01 dovecot: Error: child 20908 (imap) killed with signal 11 (core dumped) Jul 22 13:56:43 dovecot: Error: child 19466 (imap) killed with signal 11 (core dumped) Jul 22 14:06:16 dovecot: Error: child 22629 (imap) killed with signal 11 (core dumped) Jul 22 14:08:17 dovecot: Error: child 22879 (imap) killed with signal 11 (core dumped) Here is my config section, which I added to enable virtual plugin: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual subscriptions = no } and "virtual" to mail_plugins in imap and lda section. Full dovecot -n config provided at the end of this message. I'm not sure, if it is save to enable virtual location for all users using the same path, but the main goal for me - to create dovecot-virtual files once for all users.

[Dovecot] Problem with INTERNALDATE when the year in localtime and GMT different
by 도원철 21 Jul '09

21 Jul '09

In my thought utc_offset function in src/lib/utc-offset.c returns wrong offset value when the year in localtime and GMT different. /* max offset of 24 hours */ if (ltm.tm_yday < gtm.tm_yday) offset = -24 * 60; else if (ltm.tm_yday > gtm.tm_yday) offset = 24 * 60; else offset = 0; I think this code should be modified as followings. /* max offset of 24 hours */ if ((ltm.tm_year == gtm.tm_year && ltm.tm_yday < gtm.tm_yday) || (ltm.tm_year < gtm.tm_year)) offset = -24 * 60; else if ((ltm.tm_year == gtm.tm_year && ltm.tm_yday > gtm.tm_yday) || (ltm.tm_year > gtm.tm_year)) offset = 24 * 60; else offset = 0; On 1 Jan. 2009, I found an error related to this code. The intrenal date of message recieved at 01-Jan-2009 07:17:38 was not display as it received. The protocol log was as followings. FETCH (INTERNALDATE “01-Jan-2009 07:17:38 -3900” RFC822.SIZE 1597 FLAGS (\Seen) ENVELOP (“Thu, 1 Jan 2009 07:17:38 +0900 (KST)” … The INTERNALDATE must be “01-Jan-2009 07:17:38 +0900”, but it was "01-Jan- 2009 07:17:38 -3900". This error may be caused by the bug in utc_offset.c. How do you think?

[Dovecot] [Bug] dovecot deliver v1.2.1 segfaults
by Nikita Koshikov 21 Jul '09

21 Jul '09

Hello list, I have noticed strange dovecot behavior with exim system-filter. I'm using exim+dovecot setup. My exim configuration have system filter enable, which restrict some attachments, like exe, vbs etc. When message with forbidden attachment received, exim accept the message, then construct bounce-message(Reject reason + original message) and returns it to sender. Trying to deliver such messages, I always get segmentation faults and message stayed in exim's queue. Others common delivers work fine. This only happens with bouncing system-filter messages. Steps to reproduce: 1) Create message with forbiden attachment 2) Send message. 3) Get segmentation fault. Here is more details: exim -d+all -M 1MSn7r-0003hN-BG (this command runs delivery from exim's queue) 13:14:23 11570 --------> koshikov.n(a)domain.com <-------- 13:14:23 11570 locking

[Dovecot] vpopmail and shared mailbox
by David Fuchs 21 Jul '09

21 Jul '09

hi all, I'm a long time courier-imap user and just switched to dovecot-1.2.1. my MTA is qmail and all user accounts are virtual vpopmail users. getting dovecot to work was mostly painless, but I am desperately trying to share a user's mailbox and can't seem to figure out how. unfortunately the documentation is not very helpful. I am trying to share the mailbox /home/vpopmail/domains/ example.com/someuser/Maildir here's what I put in dovecot.conf: namespace shared { separator = . prefix = shared.%%u. location = maildir:/home/vpopmail/domains/%%d/%%n/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } I then logged in as someuser and did a "setacl anyone Inbox lrip". /home/vpopmail/domains/example.com/shared-mailboxes.db now contains an entry shared/shared-boxes/anyone/someuser(a)example.com 1 and /home/vpopmail/domains/example.com/someuser/Maildir/dovecot-acl has anyone ilpr however, when I connect to the server, the client does not see the "shared" namespace. also, dovecot seems to be creating empty shared-mailboxes.db in /home/vpopmail/domains/example/ (missing .com!). I'm very confused at this point, but I'm sure someone has gotten this to work and can help me out. fwiw, the output of dovecot -n is appended. thanks! - Dave.

[Dovecot] Problem with quota-dict
by Sascha Bendix 20 Jul '09

20 Jul '09

Hi, I wanted to migrate a mailserver from cyrus to dovecot. The new setup was using postfixadmin let the domain admins configure the hostet domains. To view the used quota in postfixadmin the usage of the quota dict backend is required. I have configured it according to the wiki but everytime I connect I get a sucessfully login and then every next command hangs. It seems to me, that the dict process itself is hanging. I even startet with a fresh mail box. The only way to login with my setup is to disable quota for the used protocol. My system is debian lenny based with dovecot 1.0.15 and PostgreSQL 8.3.7 as database server. My config is the following: # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s managesieve listen: [::] ssl_cert_file: /etc/ssl/certs/server.crt ssl_key_file: /etc/ssl/private/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting: Ready. first_valid_uid: 8 last_valid_uid: 8 mail_privileged_group: mail mail_location: maildir:/var/mail/%d/%n mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl mail_plugins(imap): quota imap_quota acl mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u pop3_uidl_format(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/mail/sieve/%d/%n sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): /var/mail/sieve/%d/%n.sieve namespace: type: private inbox: yes auth default: user: dovecot-auth passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: dict:storage=10240 proxy::quota acl: vfile:/etc/dovecot/acls sieve: /var/mail/sieve/%d/%n.sieve dict: quota: pgsql:/etc/dovecot/dovecot-dict-quota.conf My /etc/dovecot/dovecot-dict-quota.conf: connect = host=localhost dbname=mail user=mail password=dovecot-passwort table = quota select_field = current where_field = path username_field = username My database table: CREATE TABLE quota ( username character varying(255) NOT NULL, path character varying(100) NOT NULL, "current" integer, CONSTRAINT quota_pkey PRIMARY KEY (username, path) ) WITH (OIDS=FALSE); ALTER TABLE quota OWNER TO mail; -- Trigger: mergequota on quota -- DROP TRIGGER mergequota ON quota; CREATE TRIGGER mergequota BEFORE INSERT ON quota FOR EACH ROW EXECUTE PROCEDURE merge_quota(); connect = host=localhost dbname=mail user=dovecot password=jianueyeePeev5o table = quota select_field = current where_field = path username_field = username My dovecot logfile with mail_debug=yes: Jul 20 21:06:17 skippy dovecot: Dovecot v1.0.15 starting up Jul 20 21:06:17 skippy dovecot: auth(default): pgsql: Connected to mail Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Loading modules from directory: /usr/lib/dovecot/modules/pop3 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Module loaded: /usr/lib/dovecot/modules/pop3/lib10_quota_plugin.so Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Effective uid=8, gid=8 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): maildir: data=/var/mail/domain.tld/user Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): maildir: root=/var/mail/domain.tld/user, index=/var/mail/domain.tld/user, control=, inbox= Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: uri = proxy::quota Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: byte limit = 52428800 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: count limit = 0 Jul 20 21:07:07 skippy dovecot: pop3-login: Login: user=<user(a)domain.tld>, method=PLAIN, rip=::ffff:1.2.3.4, lip=::ffff:1.2.3.5, TLS Jul 20 21:07:07 skippy dovecot: dict: pgsql: Connected to mail Jul 20 21:07:07 skippy dovecot: dict: Timeout leak: 0x40e150 Jul 20 21:07:07 skippy dovecot: dict: WARNING: there is no transaction in progress I'm a little bit clueless because there is no significant output (even in strace).

[Dovecot] Filesystem size limitation?
by Tommy Ng 20 Jul '09

20 Jul '09

I'm new to dovecot, nice to meet you guys here. Referring to Redhat, 32bit Linux v5 GFS supports 16TB filesystem size while 64bit version supports 8 EB (1EB = 1024TB) size. Reference: http://www.redhat.com/rhel/compare/ My question is, any limitation on a single filesystem (Redhat GFS) that Dovecot can handle? or Dovecot depends only on the limitation of OS?

[Dovecot] Bug in Dovecot Managesieve or Horde ?
by Christian Felsing 20 Jul '09

20 Jul '09

Hello, there is a problem between Dovevot 1.2 Managesieve 0.11.7 and Horde webmail 1.2.2 (possibly also in 1.2.3) in imap4flags $ telnet localhost 2000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. "IMPLEMENTATION" "dovecot" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include body variables enotify environment" "SASL" "PLAIN LOGIN" "STARTTLS" "NOTIFY" "mailto" "VERSION" "1.0" OK "taunusstein.net imap4/pop3 ready." This shows imap4flags, Cyrus sieve shows imapflags instead that. Horde Ingos does not like that and complains about missing "imapflags". Two small patches in Horde code resolves that, but I do not know if that's the right way. cd webmail2/ingo/lib vi ./Script/sieve.php: function requires() { //return array('imapflags'); return array('imap4flags'); } vi ./tests/SieveTest.php: function testBlacklistMarker() { $bl = &new Ingo_Storage_blacklist(3); $bl->setBlacklist(array('spammer(a)example.com')); $bl->setBlacklistFolder(INGO_BLACKLIST_MARKER); $this->store($bl); //$this->assertScript('require "imapflags"; $this->assertScript('require "imap4flags"; if address :all :comparator "i;ascii-casemap" :is ["From", "Sender", "Resent-From"] "spammer(a)example.com" { addflag "\\\\Deleted"; keep; removeflag "\\\\Deleted"; stop; }'); } After that, Horde Ingo likes Dovecot mailsieve. Is it a bug of mailsieve ? Regards Christian

[Dovecot] dovecot 1.2rc5 fails to authenticate user via GSSAPI
by Michal Hlavinka 20 Jul '09

20 Jul '09

Hi, we're facing problem where dovecot 1.2rc5 is not able to authenticate user via gssapi. (I'm forwarding information from red hat's bugzilla) Steps to reproduce: 1. Install dovecot with kerberos support, create mailboxes for the client 2. Get initial credentials on client side 3. Attempt to log in via dovecot using gssapi -> login failed Client side 1. Email client displays: "[AUTHENTICATIONFAILED] Authentication failed." 2. klist before login shows: Valid starting Expires Service principal 06/18/09 20:01:01 06/19/09 20:01:01 krbtgt/realm@realm 3. klist after login attempt shows: Valid starting Expires Service principal 06/18/09 20:01:01 06/19/09 20:01:01 krbtgt/realm@realm 06/18/09 20:01:28 06/19/09 20:01:01 imap/mail.domain@realm Server side 1. /var/log/maillog: dovecot: auth(default): gssapi(user,192.168.0.1): authn_name not authorized dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<user>, method=GSSAPI, rip=192.168.0.1, lip=192.168.0.2, TLS ---------------- It is possible for the same user to login via other mechanisms. The issue reproduced with different email clients. Evolution and a custom java-based client were attempted. example of dovecot.conf: protocols = imap mail_location = maildir:/home/virtual/%u/Maildir protocol imap { } auth_krb5_keytab=/etc/dovecot.keytab auth default { mechanisms = gssapi userdb static { args = uid=vmail gid=vmail home=/home/virtual/%u } } ------------------------- Exactly the same dovecot setup was working just fine with dovecot 1.1 series. Authentication using kinit works just fine and kerberos infrastructure is functioning well as I use kerberos auth for other services like apache and ssh successfully. /var/log/maillog with using auth_debug=yes can be found here: https://bugzilla.redhat.com/attachment.cgi?id=348710 Regards, Michal Hlavinka

[Dovecot] RFC: Different quota for dovecot and deliver
by Philipp Marek 20 Jul '09

20 Jul '09

Hello everybody, I've been with this question in IRC the last days, but no solution was found. So I looked into the sources, and came up with the attached (untested, not even compiled) patch against 1.2.1. Rationale ----------- I'd like to bounce on the external side, which is quite easy if the quota is stored in a SQL database; then eg. postfix can directly query it, and reject accordingly without doing any real work. Now, as discussed some time ago on the postfix list (cannot find it anymore, sorry), it would be best to *not* bounce internally, ie. when the mail is delivered in the mailbox, but to allow a small bit of over-usage instead. Thoughts ---------- Why don't we simply set the value seen by postfix down a bit? I don't think that this is the correct solution; if the difference between these two values is smaller than the allowed mail size we'd get internal bounces again. (And we wouldn't allow to *get* the amount of mail, btw, only to use it via COPY.) There are more complicated schemes, like putting a slightly higher quota in the configuration, and subtracting a bit in postfix again. I wouldn't see that as aesthetical, too. Furthermore all such schemes have the problem of being unstable - larger mails get (internally) rejected earlier than small ones. Wanted behaviour ------------------ What I'd like to achieve is that postfix uses the trigger value from the Database as well, but that deliver allows a small bit more - say 5, 10, or 20MB. Then one incoming mail simply makes the quota go over the defined limit; now postfix no longer accepts mail, but the incoming queue (amavis etc.) can be drained - at least if there's not some big hiccup in queue processing, and that's why I'd like to use a *different* quota, and not simply *none* (for deliver). Idea to solve this -------------------- The idea is that in the SQL configuration the name of an environment variable can be given to the SELECT query; this name, and the value of the environment variable, are used as an additional WHERE constraint. It would be much nicer if a stored procedure could be called with parameters (like Postfix allows), but that would mean a fair bit of change to dovecot. (And in Postgres at least the query could be rewritten with rules - but that's not that nice, either.) I've now looked into the sources, and tried to sketch the basic change that I imagine; please see the attached patch. Would something like that be acceptable? I thought for some time whether the additional query should use the filename part of the executable; then similar things could be done. But as this is a bit more general I settled for the environment variable. Thank you for all answers. Regards, Phil

[Dovecot] Changed URLs of the automated Debian repositories
by Stephan Bosch 19 Jul '09

19 Jul '09

Hi, Due to the advent of Dovecot v2.0, I restructured the automated Debian package builder to build packages for v2.0 as well. Those of you using the automated repositories should change their /etc/apt/sources.list files as follows: Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main Dovecot v2.0 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-2.0 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-2.0 main Dovecot v2.0 ManageSieve and Sieve need quite a few changes yet to become fully functional. ManageSieve is even still pretty much broken for the new Dovecot version. This means that Dovecot v2.0 (at least with respect to the Sieve support) is not quite ready for testing. That is also why the the v2.0 repository is not mentioned in the wiki. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Hi, I've changed the name of the Sieve Mercurial repository form dovecot-libsieve to dovecot-1.2-sieve, to signify the Dovecot version it applies to. The URL thus looks as follows: http://hg.rename-it.nl/dovecot-1.2-sieve Note that there are already dovecot-2.0-sieve and dovecot-2.0-managesieve repositories, but these are still somewhat broken in multiple ways and I wouldn't call these ready for testing yet.

[Dovecot] dsync - one or two ways?
by Timo Sirainen 18 Jul '09

18 Jul '09

dsync in Dovecot v2.0 tree is a new utility for syncing a mailbox in two locations. Some things it can be used for: - Initially transfer a mailbox to another server via SSH - A faster sync done to an existing mailbox, sending only changes - A superfast sync based on modification sequences. - Source and destination mailboxes can use different formats (convert-tool will be history) dsync can handle all kinds of conflicts in mailboxes, handle mailbox deletions, renames, etc. So it's safe to sync even if both source and destination mailboxes have had all kinds of changes. Now, the question is: Does anyone want dsync to only sync changes from source to destination, instead of doing a full two-way sync? I think in typical cases where you'd think you would want only one-way sync are also the cases where there's no changes coming the other way in any case.

[Dovecot] SMTP Auth Issue for non /etc/passwd accounts
by Mark R. Baith 17 Jul '09

17 Jul '09

Folks - With Dovecot 1.0.7, we're seemingly unable to authenticate users for out-going SMTP access who are not residing directly within the main system passwd/shadow files. (I.e. the users seeded within our non-system "dovecot" userdbs & passwd files have no "smtp-auth" joy! (Ye olde "Relaying denied. Proper authentication required") I've mucked around with this from several different angles and clearly saslauthd is the sticking point in terms of "locking-in" on the /etc system files ONLY for smtp-auth. Our defined dovecot user/passwd files are entirely ignored. Can anyone provide a direction regarding the appropriate smtp-auth in-road? Thanks, -M Regards, M

[Dovecot] Question regarding layout.
by Johan Hendriks 17 Jul '09

17 Jul '09

Hello all. I have a question regarding my mail flow. We have some users who are in a mail group (alias), and these alias receives a lot of attached documents. So i have the document in all the mailboxes of the alias. If the attached document is 2MB and that is not rare, i have 10 times 2 MB on my mail server. Is there a way to tackle this. Maybe by making the alias a mailbox itself and give other users acces or are there other options. Also i have very lame and lazy users. They refuse to clean thrash cans (i asked about that earlier,and got that tackled through the expire plugin.),also the do not remove old mail not even reading it. So is there also a option to remove mail that is not been opened, and is older than xx days or weeks.

[Dovecot] Can Dovecot Proxy GMail?
by Paul Carter-Brown 16 Jul '09

16 Jul '09

Hi, We are using gmail (google apps) across our company with most users using outlook (windoze) or evolution (linux) and imap/pop based on user preference. We are having issues in that our internet links are fairly slow and when users download mails they get frustrated with the time it takes and often get timeouts and issues where outlook fails to fetch a mail yet gmail thinks it was retrieved - users then complain of "missing" emails. Is there a way that we could use dovecot (or similar?) to act as an imap "proxy" and users connect to dovecot while dovecot connects to gmail? Thanks Paul

[Dovecot] Expire plugin - where to start?
by Frank Leonhardt 15 Jul '09

15 Jul '09

I'm running Dovecot 1.1.3 on FreeBSD 7.0 with procmail 3.22 sorting the output of Spamassassin. Just for me and a few friends. I didn't like the ageing 'standard' IMAP implementation so I thought I'd give Dovecot a try and it's really impressive. However, I'm a complete newbie to its inner workings. Spamassassin is able to find plenty to chew on so the "Probable spam" mbox (note) fills up fast. I obviously want to zap the old stuff in there automatically. It seems to me that the expire plugin is the thing I need BUT reading the documentation: http://wiki.dovecot.org/Plugins/Expire Leaves me to scared to try anything. It's all working and I don't want to break it or delete anyone's mail. The problem that the wiki isn't accurate to the version I'm running. For example /usr/libexec/dovecot/expire-tool.sh doesn't exist. Okay, this isn't Linux, and there's something likely where I'd expect it on BSD (/usr/local/...) - but it's a binary, not a shell script. It may be a direct replacement AFAIK, but it may not. I've been reading the old mailing list about problems with 1.2 and this reinforces the feeling that the wiki is out-of-sync. Am I being paranoid? Possibly, but I don't want to be posting a "Help! I've wrecked my config and deleted all my friend's mail" type message. (Okay, I'd take a backup first). So could some kind person point me at the latest documentation? Thanks, Frank.

[Dovecot] multiple authentication mechanisms/passwords for same account
by Tapani Tarvainen 15 Jul '09

15 Jul '09

This may be trivial but reading the documentation I can't find a clear answer: If multiple authentication mechanisms (or multiple databases for one) are defined, does it allow one user account to have several (at least two) alternative passwords (so that any of them would work)? Or does it first map an account to a fixed authentication mechanism/password and if it fails, others won't be tried? -- Tapani Tarvainen

[Dovecot] v3.0 architecture
by Timo Sirainen 15 Jul '09

15 Jul '09

I just had a thought. It's probably going to be too big of a change for v2.0, so something to think about for v3.0: Supporting multiple UIDs is difficult. Currently expire-tool and v2.0's LMTP server are implemented in a way that it's always running as root and only temporarily dropping privileges. So any security hole in there gives the attacker root privileges. Not very nice. With a single UID it's possible (or will be) to just use that one UID for the process without running as root. User sharing mailboxes to another user with different UID is even more difficult. Currently the only practical way to implement this is to assign read-write permissions to some group and have all mail files owned by that group. Not very nice. Sharing mailboxes between users located in different servers is impossible if the disk isn't somehow shared. All of these can be solved the same way: 1. imap, pop3, lmtp, etc. processes will be running without any privileges, very much like imap/pop3-login nowadays. Nobody-chrooted to empty directory. 2. Create storage processes that are started as needed. They can be configured in different security/performance settings: One storage process per user, one storage process per UID, setuid-root style shared storage process for multiple UIDs. 3. Mail processes talk to storage processes via some protocol. They can talk via UNIX socket or TCP/IP. If an existing connection can't handle the target UID, a new connection is made that either reuses an existing storage proces or creates a new one. 4. IMAP can finally implement truly simultaneously running queries (where it makes sense) by creating more storage processes if existing ones are busy handling longer-running commands. This also allows using the same storage process for multiple simultaneous IMAP connections and mail deliveries (and etc). The storage processes can also hang around and keep mailboxes open after all connections have closed it (dynamically figured out when it makes sense) to handle webmail clients that create lots of short-living connections or POP3 clients who poll for new mail every minute. The big problem is what the protocol should be. Use some existing RPC protocol? It should be something extensible so that a plugin in imap process can talk to a plugin in storage process, without the base processes knowing anything about the details (e.g. imap-quota plugin asking quota usage from storage's quota plugin). In any case the client side API should be asynchronous. That can make it annoyingly difficult to use though. Wonder if I could switch to erlang or something for the imap/pop3 processes :)

[Dovecot] Sieve problem: No vacation message when mail is addressed to an alias of the mailbox.
by M. Bobkiewicz 15 Jul '09

15 Jul '09

Hi, I?m facing here a wierd problem: We have a vacation messaging system using sieve. When activated the system forwards incomming messages to a given address and sents an out of office reply to the sender. This works like a charm when the mail is addressed to mailbox@domain. When the incomming mail ist addressed to alias.to.mailbox@domain the mail is delivered to the mailbox, it is forwarded to the given reciepient but there is no auto reply going out to the sender! Our setup: CentOS 5.2 + postfix 2.5.6 + dovecot 1.1.11 with domain and accounts stored in a mysql database. The script: require ["fileinto", "vacation"]; redirect "mailbox2@domain"; keep; vacation :days 1 :subject "Out of Office reply" " The auto reply text. "; Any advice is welcome, Best regards, Mike

[Dovecot] SSL_PARAMETERS_PERM_PATH
by Leo Baltus 14 Jul '09

Hi, I am not on this list so please CC me. Using dovecot-1.2.x it seems we can not configure the location of ssl- parameters.dat.tmp, it is hard coded to be in PKG_STATEDIR: ./src/master/master-settings.c: #define SSL_PARAMETERS_PERM_PATH PKG_STATEDIR"/"SSL_PARAMETERS_FILENAME This can lead to problems when you're running multiple instances on one machine. Apart from that, it would be very useful if wasn't hard- coded like that. Maybe it could be in base_dir or have a configuration option of its own? -- Leo Baltus, internetbeheerder /\ NPO ICT Internet Services /NPO/\ Sumatralaan 45, 1217 GP Hilversum, Filmcentrum, west \ /\/ beheer(a)omroep.nl, 035-6773555 \/

[Dovecot] getting Apple Mail and dovecot/IMAP to co-operate
by Jim Reid 13 Jul '09

13 Jul '09

Hi. I've been fighting a losing battle to get Apple Mail and dovecot to play nice. When dovecot is told to use mbox-style mailboxes, it's not possible to create child mailboxes. Apple Mail whines "The IMAP command “CREATE” failed with server error: Mailbox doesn't allow inferior mailboxes.". I've looked through the documentation, the wiki and searched the mail archives without finding a solution. Can anyone help? I've tried (and failed) to get a hybrid maildir/mbox setup to work like that shown on http://wiki.dovecot.org/Namespaces. When that gets plugged into dovecot.conf, Apple Mail blocks, with the Activity window saying "waiting for login" or something like that, even though a valid imaps connection and login has been established. There's nothing getting logged by dovecote for both of these problems, even when syslog is turned all the way to debug priority. Here's the current configuration info: shaun# dovecot -n # 1.1.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-RELEASE amd64 ufs base_dir: /var/run/dovecot/ syslog_facility: local4 protocols: imaps listen: *, [::] ssl_cert_file: /usr/local/etc/ssl/certs/dovecot.pem ssl_key_file: /usr/local/etc/ssl/private/dovecot.pem ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_max_processes_count: 8 login_max_connections: 32 max_mail_processes: 32 mail_privileged_group: mail mail_location: mbox:/mail/imap/%u:INBOX=/var/mail/%u mail_debug: yes mbox_write_locks: fcntl auth default: mechanisms: cram-md5 verbose: yes debug: yes passdb: driver: pam passdb: driver: passwd-file args: /usr/local/etc/dovecot-md5 userdb: driver: passwd shaun# dovecot --version 1.1.16

[Dovecot] Possible fix to an old Thunderbird related problem
by Marc Perkel 13 Jul '09

13 Jul '09

I think I might have finally fixed it. The problem was that the max_cached_connections in Thunderbird defaults to 25 and I had login process count set to 10. I think raising it to 25 ill fix it. Just posting this in case others are having this problem. What was happening was that the message counts were increasing but the messages didn't show up in the list. Or messages would appear to be empty. Restarting Dovecot or restarting Thunderbird fixes the problem temporarily. I'm hoping this annoyance will go away now.

[Dovecot] v1.2.1 released
by Timo Sirainen 13 Jul '09

13 Jul '09

http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz.sig Mainly fixes to some issues found by people when upgrading to v1.2.0. * GSSAPI: Changed logging levels and improved the messages. Changed the way cross-realm authentication handling is done, hopefully it's working now for everyone. * imap/pop3 logins now fail if home directory path is relative. v1.2.0 deliver was already failing with these and they could have caused problems even with v1.1. * IMAP: Custom authentication failure messages are now prefixed with [ALERT] to get more clients to actually show them. + Improved some error messages. - pop3: AUTH PLAIN was broken when SASL initial response wasn't given. - mbox: New mailboxes were created with UIDVALIDITY 1. - quota-fs was defaulting to group quota instead of user quota. - Fixed ACLs to work with mbox. - Fixed fchmod(-1, -1) errors with BSDs - convert plugin / convert-tool: Fixed changing hierarchy separators in mailbox names when alt_hierarchy_char isn't set.

[Dovecot] Released Sieve v0.1.8 and ManageSieve v0.11.7 for Dovecot v1.2.1
by Stephan Bosch 13 Jul '09

13 Jul '09

Hello Dovecot users, The recent Dovecot v1.2.1 release broke ManageSieve compilation. Today, I release new packages to fix this and additionally a few bugs are resolved. Changelog Sieve v0.1.8: - Fixed AIX compile problem. For portability, the typeof operator is not used anymore. + Added partial support for the deprecated notify extension. However, it turns out that the implementation provided by cmusieve is even older (2001), meaning that this is currently not backwards compatible with cmusieve. Should be fixed in next release. Changelog ManageSieve v0.11.7: * Adjusted to changes in the Dovecot login API. This release now depends on Dovecot v1.2.1 or newer. * Incorporated various small changes in IMAP into ManageSieve. This includes properly enabling the generation of core dumps. - The previous release implicitly resolved the FreeBSD script truncation error. This release adds a small correction to the code that detects the truncation. - Fixed panic occurring when many errors are produced by the Sieve compiler (bug found by Pascal Volk). - Fixed memory leak in the PUTSCRIPT command. (ManageSieve patch) - Forgot to add the managesieve_logout_format setting to the config file. Now it works (bug reported by Pascal Volk). -- The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.g… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] fchown error on tmp files

Hi, After upgrading to 1.2 I started getting fchown errors in the log.

[Dovecot] Dovecot and ACL
by Daniel Spannbauer 11 Jul '09

11 Jul '09

Hello, I try to get per-mailbox-ACLs on dovecot. So, I've modded dovecot.conf: protocol imap { mail_plugins = acl } and plugin { acl = vfile } When I telnet to dovecot an try the command "capability" there is nothing about acl. I need acl for "open-xchange" so I can share Mailboxes over the webinterface. Do I have to create the acl-file manually or does dovecot this automaticly? reagrds Daniel -- Daniel Spannbauer Software Entwicklung marco Systemanalyse und Entwicklung GmbH Tel +49 8333 9233-27 Fax -11 Rechbergstr. 4 - 6, D 87727 Babenhausen Mobil +49 171 4033220 http://www.marco.de/ Email ds(a)marco.de Geschäftsführer Martin Reuter HRB 171775 Amtsgericht München

[Dovecot] problem with convert-tool: "Invalid mailbox name"
by Ezequiel Alfíe 11 Jul '09

11 Jul '09

Hello everyone. I'm having a problem with convert-tool while trying to convert mbox folders to maildir. I'm running dovecot-1.1.16 on Centos 5.3 If the user has subfolders, convert-tool fails saying: "Mailbox conversion: Couldn't create mailbox sub/folder3: Invalid mailbox name" However, if I ran the convert-tool with the same arguments and same folders with dovecot 1.1.11 on Ubuntu 9.04 it works fine. Any pointers for troubleshooting this? Thanks in advance, Ezequiel

[Dovecot] non-lowercase usernames

Should I just make Dovecot lowercase usernames by default in v2.0? auth_username_format = %Lu Does anyone actually want to use non-lowercase usernames?

[Dovecot] Sieve on full mailbox
by ian＠comtek.co.uk 10 Jul '09

10 Jul '09

Hi, We are using dovecot with "mail_plugins = cmusieve". I have Avelsieve in SquirrelMail for users to interact with it. Is there any way I can allow users to run their sieve script on an entire mailbox? While the normal case of having messages filtered as they are delivered to the Maildir makes sense it would be useful for a few users to be able to apply their rules to every message on a one-off basis. If there is a binary which will do this job? I could adapt the SquirrelMail interface to invoke it with appropriate arguments. Thanks, Ian

[Dovecot] Dovecot delivering mail in the wrong directory location
by Tjerk Wolterink 10 Jul '09

10 Jul '09

Hello everybody,my new server is setup with postfix as a MTA and dovecot as a MDA, mysql is used as a user db, and postfixadmin is used to setup accounts. Login via pop works fine, also sending via smtp works fine. HOWEVER: when i sent a mail by hand via smtp it is delivered in the wrong directory. For example for test(a)xdatasystem.com i have the following directory: /home/vmail/xdatasystem.com/test However the mail is delivered to this directory: /home/vmail/test(a)xdatasystem.com/ I cannot figure this out as dovecot is correctly configured. ( think) Here is the important part of my dovecot.conf (sorry for the indents): === DOVECOT.CONF === *disable_plaintext_auth = no* *log_timestamp = "%Y-%m-%d %H:%M:%S "* *mail_location = maildir:/home/vmail/%d/%n/Maildir* *mail_access_groups = vmail* *first_valid_uid = 100* *first_valid_gid = 100* * * *protocol imap {* *}* * * *protocol pop3 {* *pop3_uidl_format = %08Xu%08Xv* *}* *auth default {* *mechanisms = digest-md5 plain* *passdb sql {* *args = /etc/dovecot/dovecot-sql.conf* *}* *#userdb sql {* *#args = /etc/dovecot/dovecot-sql.conf* *#}* * * *userdb static {* *args = uid=vmail gid=vmail home=/home/vmail/%d/%n* * }* * * *user = root* *}* === DOVECOT.CONF === Has anybody a clue?

[Dovecot] Optimal quota method for SQL
by Tom Sommer 10 Jul '09

10 Jul '09

Hi, I just installed 1.2.0 and I'm gonna set up some quota on my vitual users. I' ve got dovecot set up as LDA, and currently I'm using the dict-mysql method described for 1.2.0, but it's not really working at all. Am I correct in assuming that with this method I can define the quota limit in my dict (sql field)? This is my current config: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { quota = dict:user::proxy::quotadict quota_rule = *:storage=0:messages=0 } protocol lda { mail_plugins = quota ..... } I want quota to be disabled unless otherwise specified in my SQL database. // Tom

[Dovecot] Managesieve fails to retrieve scripts > 8kB on Dovecot 1.1.16
by John Marshall 10 Jul '09

10 Jul '09

After some help with debugging tips on #dovecot, I have established that a sieve script on Dovecot 1.1.16 has to be less than 8kB in order to be retrieved by a managesieve client. I have been using managesieve for about 6 months over as many 1.1.n versions of dovecot as have been around during that time and hit this problem when I upgraded to Dovecot 1.1.16. I have gone back to Dovecot 1.1.15 and can once again manage my 9kB sieve script remotely. Symptoms were that managesieve login was OK but instead of displaying my sieve script, the script editing window was empty. After 30 seconds the client gave me a timeout message. If I entered a small script in the empty client edit window and saved it, the new, small script was saved to the server and became active. I could then successfully retrieve and edit that small script. I tried hacking a few lines at a time out of my 9kB script (locally on the server). When it was down to 8.4KB I still couldn't get it through managesieve. The next hack took it down to 7.7kB and I could get that through managesieve. So, I'm guessing there's a magic 8192 number in there somewhere - perhaps a buffer? Server dovecot 1.1.16 dovecot-sieve 1.1.6 dovecot-managesieve 0.10.6 FreeBSD 7.2 Client Thunderbird 2.0.21 Sieve 0.1.6 A special thanks to all who write this stuff: it's great! -- John Marshall

[Dovecot] First V1.2 compile questions
by Stewart Dean 09 Jul '09

09 Jul '09

1) I see that the --without-pop3d option has gone away. What does this imply, i.e why was that done? Is there some other way that you now avoid compiling the POP code? Are there any other discontinued options? 2) There was some talk a while back about changing how and where the plugins were to be built and their code located. Was this implemented? If so, is there any doc on it? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Long delay checking mail with POP w/plain auth
by david hardy 09 Jul '09

I just switched from UW-IMAP to dovecot, and it all went smooth, except now I get a 4-5 second delay after connecting to the POP3 server (IMAP is fine). If I switch to auth "mechanisms=login", it is instantaneous - the delay is gone.

[Dovecot] Problem with 1.2 and sieve: failed with unsuccessful implicit keep

Hi, First, thanks for this awesome piece of software. I've just upgraded to latest dovecot, aka 1.2. I've a problem. I've started using Sieve, and everything works fine, I already received a thousand of mails without any problem. However, there's one mail which is stuck in the postfix queue because of that: Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): mkdir_parents_chown(danjou.info/jd/) failed: Permission denied (euid=8(mail) egid=8(mail)) Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): copy: i_stream_read() failed: No such file or directory Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): sieve: msgid=? <1186f9b5-0529-4622-8f4a-58462f9a4bcb(a)svr-exchange.siege.ldlc.com>: failed to store into mailbox 'INBOX': Internal error occurred.

[Dovecot] System users, mbox format and global ACLs
by Axel Luttgens 08 Jul '09

08 Jul '09

I need some help here... ;-) I'm experimenting with global ACLs, but just fail to understand very basic behaviors. So, before digging into the source code, I would really be delighted if someone could immediately point a mistake I'm making and miserably overlooking. The output of dovecot -n is provided at the end of this email. Just in case, conforming to the suggestion made in http://wiki.dovecot.org/ACL , I've specified a CONTROL directory; but I get a similar behavior without it. As far as the acl plugin is concerned, I've just specified a directory for global ACLs; whether that directory is populated or not doesn't seem to have an impact on the observed behavior. Here's the structure of the test user's home directory: total 0 drwx------ 4 testuser people 136 26 jui 13:52 . drwxr-xr-x 3 root admin 102 19 mai 16:56 .. drwxr-xr-x 4 testuser people 136 28 jui 17:09 _mailboxes drwxr-xr-x 2 testuser people 68 28 jui 17:07 _mboxesctrl ./_mailboxes: total 96 drwxr-xr-x 4 testuser people 136 28 jui 17:09 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw------- 1 testuser people 48685 25 jui 16:58 inbox ./_mailboxes/.imap: total 0 drwx------ 3 testuser people 102 19 mai 17:02 . drwxr-xr-x 4 testuser people 136 28 jui 17:09 .. drwx------ 5 testuser people 170 23 jui 18:02 INBOX ./_mailboxes/.imap/INBOX: total 88 drwx------ 5 testuser people 170 23 jui 18:02 . drwx------ 3 testuser people 102 19 mai 17:02 .. -rw------- 1 testuser people 1376 23 jui 18:02 dovecot.index -rw------- 1 testuser people 26624 28 jui 10:23 dovecot.index.cache -rw-rw-rw- 1 testuser people 10284 25 jui 17:57 dovecot.index.log ./_mboxesctrl: total 0 drwxr-xr-x 2 testuser people 68 28 jui 17:07 . drwx------ 4 testuser people 136 26 jui 13:52 .. I've tried various combinations of permissions and ownership, again without any obvious influence. The manual creation of directory ~/_mboxesctrl/.imap doesn't seem to be more helpful. So, let's go to the heart of my "problem": # telnet 127.0.0.1 imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. a1 login testuser ****** a1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in a2 list "" * * LIST (\NoInferiors \UnMarked) "/" "dovecot-acl-list" * LIST (\HasNoChildren \UnMarked) "/" "INBOX" a2 OK List completed. a3 logout * BYE Logging out a3 OK Logout completed. Connection closed by foreign host. And indeed, a file named "dovecot-acl-list" has now been created under the _mailboxes directory: ./_mailboxes: total 96 drwxr-xr-x 5 testuser people 170 28 jui 17:11 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw-r--r-- 1 testuser people 0 28 jui 17:11 dovecot-acl-list -rw------- 1 testuser people 48685 25 jui 16:58 inbox This is the only file to have been created consecutively to the telnet session. Is such a file supposed to be created there? If yes, why? I would have tended to believe that it is more a server internal matter than a name having to appear in the namespace. More generally, is such a file supposed to be created at all? After all, the configuration doesn't explicitely mention per-mailbox ACLs at all... Anyway, this is what gets written in mail.log for the whole telnet session: dovecot[82305]: auth(default): new auth connection: pid=82374 dovecot[82305]: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=49879 resp=<hidden> dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): lookup service=imap dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): #1/1 style=1 msg=Password: dovecot[82305]: auth(default): client out: OK 1 user=testuser dovecot[82305]: auth(default): master in: REQUEST 8 82327 1 dovecot[82305]: auth(default): passwd(testuser,127.0.0.1): lookup dovecot[82305]: auth(default): master out: USER 8 testuser system_groups_user=testuser uid=2001 gid=2001 home=/Volumes/ALMbpSpare/ People/a/testuser dovecot[82305]: imap-login: Login: user=<testuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot[82305]: IMAP(testuser): Loading modules from directory: /usr/ local/dovecot-1.2.rc7/lib/dovecot/imap dovecot[82305]: IMAP(testuser): Module loaded: /usr/local/ dovecot-1.2.rc7/lib/dovecot/imap/lib01_acl_plugin.so dovecot[82305]: IMAP(testuser): Effective uid=2001, gid=2001, home=/ Volumes/ALMbpSpare/People/a/testuser dovecot[82305]: IMAP(testuser): acl: No acl_shared_dict setting - shared mailbox listing is disabled dovecot[82305]: IMAP(testuser): mbox: data=~/_mailboxes:INBOX=~/ _mailboxes/inbox:CONTROL=~/_mboxesctrl dovecot[82305]: IMAP(testuser): fs: root=/Volumes/ALMbpSpare/People/a/ testuser/_mailboxes, index=, control=/Volumes/ALMbpSpare/People/a/ testuser/_mboxesctrl, inbox=/Volumes/ALMbpSpare/People/a/testuser/ _mailboxes/inbox dovecot[82305]: IMAP(testuser): acl: initializing backend with data: vfile:/usr/local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl: acl username = testuser dovecot[82305]: IMAP(testuser): acl: owner = 1 dovecot[82305]: IMAP(testuser): acl vfile: Global ACL directory: /usr/ local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls//.DEFAULT not found dovecot[82305]: IMAP(testuser): Namespace : Using permissions from / Volumes/ALMbpSpare/People/a/testuser/_mailboxes: mode=0755 gid=-1 dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/.temp.ALMbp.local.82375.f9efcb24711711fb not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/.temp.ALMbp.local. 82375.f9efcb24711711fb/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/INBOX not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/INBOX/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/dovecot-acl-list not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/dovecot-acl-list/dovecot-acl not found dovecot[82305]: IMAP(testuser): Disconnected: Logged out bytes=23/431 Why does the server seem to expect to find a temp file under ~/ _mboxesctrl/.imap?

[Dovecot] Problem with sieve and german umlauts
by M. Bobkiewicz 08 Jul '09

08 Jul '09

Dear list, I?m running a postfix (2.5.6) / Dovecot (1.1.11) on a Centos 5.2 box. I?ve written a small gui application to simply create Out of Office replys with sieve. The resulting code did work with maildrop without any problems. Now sieve fails when it meets any german umlauts like ä or ü. It just stops compiling the scripts and complains about the missing "};". A simple fix is to just replace the umlauts, but that doesn?t meet the expectations of my users. Is there any escape code I could use or any way to place the mail text outside the script? Best regards, Mike

[Dovecot] mbox format and UIDVALIDITY
by Axel Luttgens 08 Jul '09

08 Jul '09

My base concern may be illustrated with the help of that simple telnet session: # telnet 127.0.0.1 imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. a1 login testuser ****** a1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in a2 list "" % * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\HasNoChildren \UnMarked) "/" "INBOX" a2 OK List completed. a3 create new1 a3 OK Create completed. a4 create new2 a4 OK Create completed. a5 select new1 * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] a5 OK [READ-WRITE] Select completed. a6 select new2 * OK [CLOSED] * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] a6 OK [READ-WRITE] Select completed. a7 unselect a7 OK Unselect completed. a8 delete new1 a8 OK Delete completed. a9 delete new2 a9 OK Delete completed. a10 logout * BYE Logging out a10 OK Logout completed. Connection closed by foreign host. During the whole telnet session, both files "new1" and "new2" remained empty (i.e. no pseudo-message written to them), no uidvalidity-related helper file seems to have been created and no uidvalidity-related function seems to have been called. And clearly, both mailboxes "new1" and "new2" have received the same UIDVALIDITY. Those UIDVALIDITYs appear to be persistent; messages may be added to and deleted from those mailboxes, those mailboxes may be renamed... their UIDVALIDITY remain unchanged and equal to 1. In fact, any additional mailbox is created with that unique and persistent UIDVALIDITY of 1. Is this supposed to behave that way? (note that I quickly tried with dovecot 1.1.16 and could observe the same behavior) TIA, Axel # 1.2.rc7: /usr/local/etc/dovecot.conf # OS: Darwin 9.7.0 i386 protocols: pop3 imap ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/dovecot-1.2.rc7/libexec/dovecot/ imap-login login_executable(imap): /usr/local/dovecot-1.2.rc7/libexec/dovecot/ imap-login login_executable(pop3): /usr/local/dovecot-1.2.rc7/libexec/dovecot/ pop3-login mail_max_userip_connections(default): 4 mail_max_userip_connections(imap): 4 mail_max_userip_connections(pop3): 10 first_valid_uid: 2001 mail_location: mbox:~/_mailboxes:INBOX=~/_mailboxes/inbox:CONTROL=~/ _mboxesctrl mail_debug: yes mbox_read_locks: flock mbox_write_locks: flock dotlock mail_executable(default): /usr/local/dovecot-1.2.rc7/libexec/dovecot/ imap mail_executable(imap): /usr/local/dovecot-1.2.rc7/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot-1.2.rc7/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/dovecot-1.2.rc7/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot-1.2.rc7/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot-1.2.rc7/lib/dovecot/pop3 pop3_lock_session(default): no pop3_lock_session(imap): no pop3_lock_session(pop3): yes pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu auth default: debug: yes passdb: driver: pam args: * userdb: driver: passwd
