[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 trace above seemed to fail with the dotlock, and proceed to 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

[Dovecot] Handling of file "maildirsize"
by Frank Elsner 26 Jul '09

26 Jul '09

Hello, My "exim" is doing the deliveries, "dovecot" handles POP/IMAP. Exim Log shows: 2009-07-24 14:03:40 1MUJUy-0001Jr-B0 == user(a)domain.tu-berlin.de R=maildir_user T=maildir_delivery defer (2): No such file or directory: while opening or reading /var/Mail/Boxes/u/user/maildirsize 2009-07-24 14:20:32 1MUJUy-0001Jr-B0 => user <user(a)domain.tu-berlin.de> F=<user(a)domain.tu-berlin.de> R=maildir_user T=maildir_delivery S=2061 QT=16m52s DT=0s The user was active using IMAP at 14:03:4*. 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

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. Regards, Pascal -- The trapper recommends today: 5e1f1e55.0920700(a)localdomain.org
