[Dovecot] Can't find next message offset

Hi, I am getting a lot of warnings since upgrading to 1.1rc10 (from rc4): mbox /home2/seta/Mail/Sent: Can't find next message offset for uid=12 Almost always, it is the Sent or Trash folders that are giving these.

[Dovecot] Migrate to 1.1 from 1.0.14
by Nicolas Letellier 19 Jun '08

19 Jun '08

Hello. I see dovecot 1.1 will be release very soon. I'm thinking about a migration from my 1.0.14. The migration job will be hard/long? I see in http://wiki.dovecot.org/Upgrading/1.1 that dovecot-uidlist file are in a new format. It will be problem for Courier (pop/imap) upgrades? (today, I often upgrade old mailboxes in Courier to my Dovecot server). Best regards, -- - Nicolas.

[Dovecot] Using checkpassword to block ips?
by Larry Ludwig 19 Jun '08

19 Jun '08

Hi new to the list, but we are a long time user of Dovecot via DirectAdmin control panel. We, like everyone else, are seeing an increase in dictionary attacks of POP/IMAP. We want to block them. I've searched the mailing list and found a few recommended fail2ban, which really won't work for our case. We need to do this over many machines and not one or two. We also like to gather info at the network wide level. Hackers know about attacking specific server/ips too often and we've seen much more distributed attacks that go under the radar of one server monitoring setup. We've designed our own system and use a local RBL to distribute the blocked IPs. For ftp and ssh attacks it's worked very well. We would like to use the RBL to do the same with dovecot. >From my research it appears the best way to do this (and only currently) is with the checkpassword option. I haven't gotten it to work yet. We have: passdb checkpassword { args = /usr/local/bin/checkpassword deny = yes } As the first auth.. This should reject the connection if the IP matches. checkpassword can see TCPREMOTEIP enviornmental variable. In the checkpassword script we have: #!/usr/bin/perl sub read_uinfo { my($user,$passwd,$apop_ts); open X,"<&=3" or exit 111; $_ = <X>; # ugly; should use sysread instead ($user,$passwd,$apop_ts) = /^(.*)\0(.*)\0(.*)\0/; while (<X>) {}; close X; return ($user,$passwd,$apop_ts); } ($user,$passwd,$apop_ts)=$debug?(shift,shift,shift):read_uinfo; $ipaddr=$ENV{TCPREMOTEIP}; $result=system("/usr/sbin/checkdnsbl $ipaddr"); if ( $result == 0) { @ENV{"SHELL","USER","HOME"} = ($shell,$user,$home); exit 0; } else { exit 1; } My questions are as follows: - Can the deny = yes be used with checkpassword? - What am I doing wrong with the script? It should reject only the connections that are in the RBL. It blocks all -L -- Larry Ludwig Empowering Media 1-866-792-0489 x600 Managed and Unmanaged Xen VPSes http://www.hostcube.com/

[Dovecot] quote-warning details
by Alexander Prinsier 19 Jun '08

19 Jun '08

Hello, I have some questions on how quota-warning is supposed to work. -Does it keep a state, so that it doesn't send the same warning several times? Or should the script itself do something to remember it already sent a warning? -When exactly does it run? Does it run when deliver runs? Or only when the user accesses it's mailbox? Thanks, Alexander

[Dovecot] dovecot as gmail imap proxy
by Farkas Levente 18 Jun '08

18 Jun '08

hi, may be this is a bit of topic, but i hope not. it's always a big question which is the better to choose a hosting provider to keep and manage you mail or setup your own mail server, hosting, virus and spam filter etc.. now as more and more people and company move to gmail or google apps mail service it seems google can't handle the load and it's getting more and more slower. what's more not just the imap interface but nowadays the web interface used to be hang or even stop working. it's getting more and more annoying that the speed is worst than in a 10 years ago. i thing about how can this be solved without totally give up gmail as a mail service provider (and may be they can solve it in a few months/years:-). would it be possible to create a dovecot server as an imap proxy for gmail and google apps? imho many people/company would be love to use such a setup where he can use gmail in vacation or any other time, but when the email is real critical apps (not acceptable to wait 1 minutes for an email to load or to open a folder/label) than he can use a proxy server eg. dovecot which act as a imap proxy to gmail and can be hosted on closer, faster server and this speed problem never happend. what's more it can be used as a mail backup server too. anybody has any such setup, idea? would it be possible with dovecot. any other suggestion? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] don't follow symlinks when creating mailbox list
by Dan Horák 18 Jun '08

18 Jun '08

Hi, this issue was discussed here twice in the not so far history (http://www.dovecot.org/list/dovecot/2008-January/028317.html, http://www.dovecot.org/list/dovecot/2008-February/029147.html) but I need to open it again as it makes problems for our users on one side and on the other side we don't want to diverge from the upstream sources in our packages. I agree with Timo that simply disabling the symlink following in creating the mailbox list can give a false sense of security so the question is whether a permanent solution can be developed and how it should look like?

[Dovecot] Mercurial repositories for ManageSieve and Sieve
by Stephan Bosch 17 Jun '08

17 Jun '08

Hello Dovecot users, Recently I was asked to use Mercurial for the ManageSieve development just like Dovecot. As a matter of fact I have been using Mercurial for some time now. Now that I am back from a short and active vacation I am ready to publish my repositories. The repositories are publicly available at: http://hg.rename-it.nl/ The -patch repositories are so-called Mercurial Queues (MQ) repositories. This provides an easy (quilt-like) means to manage patches over an upstream source repository like the one that exists for Dovecot. The patches are managed in a repository called 'patches' below the .hg directory in your main repository. Currently, these MQ repositories only have the managesieve.patch witch is the actual patch I refresh and release each time Timo makes a new Dovecot release. The following command sequence shows how to incorporate the managesieve patch repository in a freshly cloned dovecot-1.1 tree: hg clone http://hg.dovecot.org/dovecot-1.1 cd dovecot-1.1 hg clone http://hg.rename-it.nl/dovecot-1.1-managesieve-patch .hg/patches hg qpush When updating the dovecot tree it is important to unapply all patches before performing 'hg pull' on the dovecot tree: hg qpop --all hg pull hg update hg qpush This otherwise results in a multi-head situation which can be resolved using a 'hg rollback' or using 'hg qpop --all' afterwards, which should gracefully clean up the situation (never merge the heads!). Updating the patch repository works as follows: hg qpop --all hg -R .hg/patches pull hg -R .hg/patches update hg qpush After 'hg qpush' the dovecot repository is patched and can be compiled as explained for the normal patch method using the .diff.gz (don't forget ./autogen.sh for compiling dovecot in a mercurial repository). The actual ManageSieve implementation for Dovecot-1.1 is available as a separate package and thus there exists a separate repository for it. Its compilation is no different from the .tar.gz releases, except for the fact that (just like for dovecot) ./autogen.sh needs to be executed before configure. The new (and highly experimental) Sieve implementation is available as the dovecot-libsieve repository. It contains a README file that should explain most of its features and the installation procedure. This is currently still not release-ready and should not be used for any important mail whatsoever. I publish this for people who want to test and play around with it to provide feedback on early bugs and (release-critical) missing features. The TODO and README files provide an overview of my current progress towards a first release. Regards, Stephan.

[Dovecot] quota-warning.sh
by Drew Marshall 17 Jun '08

17 Jun '08

Hi I have just installed Dovecot (Moved from Courier-IMAP) and have just about everything running well thanks to some great docs in the wiki (Thank you to all those who contributed!) however I have not managed to get the quota warnings working yet. I have done much Googling and come back with some oldish posts which help me to understand how the quota warnings work but having looked at all this I have realised I don't have a quota-warning.sh script in /usr/local/bin where the config suggests it ought to be. In fact, I don't have a file by this name any where on the box. I have downloaded both 1.1 source (Which I'm running) and 1.0 and I can't find this anywhere in the sources or the tarball. Could some one tell me where I can find this or am I supposed to make my own? If so is there and example that I can follow?

[Dovecot] Caseless folder delivery?
by Jay Levitt 16 Jun '08

16 Jun '08

I'm using exim4 to deliver into dovecot 1.1, and using plus-addressing to deliver mailing lists directly to appropriate folders in my "lists" mailbox. I created a file called /folder-map.lists that looks like ## folder-map.lists dovecot: Dovecot lpedge: Linux PowerEdge ... and so on. So mail to lists-lpedge(a)jay.fm goes to the "Linux PowerEdge" folder. The one annoying thing: I'd like to avoid creating explicit folder-map entries where the plus-address suffix is identical an existing folder name. That *almost* works, but I like to name my folders with appropriate capitalization, and deliver doesn't seem to have a way to do "caseless" delivery. For instance, ideally, I wouldn't have to create the "dovecot: Dovecot" entry; mail to my lists-dovecot(a)jay.fm address would go into the "Dovecot" folder. I can't figure out how to do this. Is there a way to do that using deliver? Could there be? Relevant portions of the exim configuration follow. (And, p.s., am I using the new -a and -m options correctly? Are they used for anything yet?)

[Dovecot] Need help configuering Dovecot to support folders that contain sub-folders and messages
by Dan Roberts 14 Jun '08

14 Jun '08

Hi - Last year I set up a new CentOS 5 server and through the install process permitted it to set up dovecot as my IMAP server. ./dovecote --version returns "1.0.rc15" With the system up and running I moved the tar files of my old email accounts over and everything seemed to be just fine. Recently I have upgraded my primary workstation to a Mac Pro - and that of course has it's Mail application. Let me summarize briefly to be sure that I don't omit some minor detail that makes all the difference in the world. Previously I used Netscape 7.2 as my mail client and then went over to Thunderbird on the PC - in either application, under Server Settings / Advanced I had to uncheck the box "Server supports folders that contain sub-folders and messages". Then whenever I attempted to add a new subfolder I would be given a choice - "This server restricts folders to two special kinds. Allow your new folder to contain: [] Folders Only [x] Messages Only". Though perhaps not ideal, this has worked ok up till now. The Leopard Mail application doesn't seem to have this sort of support - it assumes that every folder or subfolder can and should contain both, so all I get are folders that can hold messages. This is a problem as I can't create any new folders to reorganize mail. Though I had thought about resolving this, or at least trying to when I first encountered it - life got busy. So my skills have become a bit rusty and I have not done anything about it. But now I would like to. I ported over my email and my wife's - so perhaps there is some legacy setting in those folders that prevents the bliss of folders and mail in the same subfile. But I created a new email account for my daughter and that has the same limitation. In Leopard mail, folders to hold folders look White, whereas folders to hole mail look blue. In Thunderbird Folders to hold Folders are in Italics whereas Folders to hold mail are normal font. I am also using Webmin to simplify access to the server, but I don't see anything obvious under the dovecot tool for this. The installation was the basic default, so far as I can remember. I have run Yum to update the files and at last review there was nothing outstanding. Regarding my configuration, dovecot -n reports as follows: [root@trailrunner sbin]# ./dovecot --version 1.0.rc15 [root@trailrunner sbin]# ./dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap imaps listen: disable_plaintext_auth: yes login_dir: /var/run/dovecot//login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd [root@trailrunner sbin]# Truly hoping that someone can help me resolve this. While I can use Thunderbird, I do like the Apple Mail feature of seeing the summary of email at the top of the list. Appreciate the help and insights - Cheers Dan

[Dovecot] Need a quick, safe method to empty /home/user/Maildir/{.Junk, .Trash}
by Jeff Kowalczyk 13 Jun '08

13 Jun '08

I have some (Thunderbird client, dovecot-1.0.13, Maildir) users who get an appalling amount of spam-with-attachment, and it's causing backups to take an inordinate amount of time. I'll implement some quota and server-side spam management when I go to dovecot-1.1, but in the meantime: What is the safest way to empty all messages within, but not delete, the following folders from the server command line: /home/user/Maildir/.Junk /home/user/Maildir/.Trash I don't want the Thunderbird-2.0.14 client to report corrupt indexing, or worse not show the folder at next use. Thanks.

[Dovecot] 9GB of messages in /tmp
by Charles Marcus 13 Jun '08

13 Jun '08

Hello, Well, I have a brain-dead user (using Thunderbird 2.0.0.14) who just won't listen when I tell them not to try to move 5000+ messages at one time (or if deleting, bypass the Trash), and they managed to royally screw up their maildirs... I have two problems... 1. The /tmp directory has 9+GB in it... can I just rm tmp/* on that directory without making this problem worse? and 2. One of the directories they were moving now has 5 copies of a whole bunch of messages... I'm very dangerous when it comes to command-line work beyond really basic stuff, and my scripting skills are less than inspiring... Is there a relatively safe command-line way of finding all messages that have more than one instance, and deleting all but the last instance? Tia... -- Best regards, Charles

[Dovecot] "Disable non webmail IMAP access" in vpopmail and Dovecot
by Alessio Cecchi 13 Jun '08

13 Jun '08

Hello, i'm using in my installation qmail+vpopmail and now I have migrated from courier-imap to dovecot. Dovecot is very much faster with large mailbox than courier-imap. But I have a problem. vpopmail has a feature that allows you to "Disable non webmail IMAP access", many webmail using imap as if they were, and they are, a client IMAP. vpopmail give me the ability to disabile IMAP, expect for 127.0.0.1, both for individual users than for single domain. So i can grant IMAP access, from remote client, only for some users but webmail access for all. Here you can read some of my messages in the vpopmail's list: http://www.mail-archive.com/vchkpw@inter7.com/msg25880.html But with dovecot this feature seems not to be compatible. A friend of the vpopmail's list sent me a patch for dovecot but I can not get it to work: >->->->->->->->->->->->->->->->->->->->->->->->->->-> Hi Alessio, i spent over 5 hours looking for a solution to this problem and i found one working for me in dovecot sources edit src/auth/passdb-vpopmail.c than add char *remotehost = net_ip2addr(&auth_request->remote_ip); auth_request_log_info(auth_request, "vpopmail", "remote ip is: %s", remotehost); before if (((vpw->pw_gid & NO_IMAP) != 0 && line than modify the condition line to look like: if (((vpw->pw_gid & NO_IMAP) != 0 && strcmp(auth_request->service, "IMAP") == 0 *&& strcmp(remotehost, "127.0.0.1") != 0*) || ((vpw->pw_gid & NO_POP) != 0 && strcmp(auth_request->service, "POP3") == 0)) { auth_request_log_info(auth_request, "vpopmail", "%s disabled", auth_request->service); password = NULL; *result_r = PASSDB_RESULT_USER_DISABLED; } else ............... this way you will preserve webmail access and cut imap from external in case -i limit is defined in vpopmail hope it helps <-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< Can someone help me in making compatible this useful feature of vpopmail with dovecot?

[Dovecot] configure error on HP-UX: C99 compatible vsnprintf() call
by Woonsan Ko 13 Jun '08

13 Jun '08

Hi All, I tried to build dovecot-1.1.rc9 on a HP-UX machine, but failed to configure with the following message: configure: error: You don't appear to have C99 compatible vsnprintf() call The environment is like the following: - command: ./configure - uname: HP-UX B.11.23 U ia64 - aCC version: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003] Also, I tried to run `./configure CC=c99' and `./configure CC="/opt/aCC/bin/aCC -Ae" also, but the result was the same. I'm not sure, but the HP C compiler does not seem to support C99 fully with vsnprintf() call. Is there any workaround for this problem? TIA, Woonsan

[Dovecot] [Patch] Fix delay on imao-append
by Bruno Prémont 13 Jun '08

13 Jun '08

Dovecot version: 1.1-rc8, 1.1-rc9 System: Linux-2.6.2x User-Agent: claws-mail-3.3 and 3.4 When appending messages (e.g. copy from mailclient local folder or second server to dovecot imap folder) dovecot answers with: <tag> OK [APPENDUID <n> <m>] Append completed\r\n This answer often reaches the client as two or more TCP packets, the client (when not using TCP_NODELAY on its socket) ACKs with some delay. When copying lots of (small) messages this delay has a very negative impact on copy time even though there are lots of network and system resources available. Sample sniffer output on client host: ... 1 0.0000 claws dovecot IMAP Request: 14639 APPEND "Test" (\Seen) {853} 2 0.0033 dovecot claws IMAP Response: +OK 3 0.0034 claws dovecot IMAP Request: <message> 4 0.0096 dovecot claws IMAP Response: 14639 5 0.0467 claws dovecot TCP 33453 > imap [ACK] 6 0.0481 dovecot claws IMAP Response: OK [APPENDUID 1204729411 2] Append Completed. 7 0.0481 claws dovecot TCP 33453 > imap [ACK] ... The delay of about 35ms between packet 4 and its ACK in packet 5 causes copies from client to server to be extremely slow. (Client and server on same 100Mb LAN, same result if client and server are on same host) The attached patch makes dovecot send the whole answer in a single packet, thus not triggering the delay issue. As far as I found out the delay is generated by Naggle algorithm, this algorithm being used by Linux TCP stack for small packets with the aim of improving payload/overhead share.

[Dovecot] How many imap processes per user
by Martijn de Munnik 13 Jun '08

13 Jun '08

Hi, I'm using dovecot for the first time on a production server (before dovecot I used bincimapd). I have a question about the number of imap (not imap-login) processes created for a user. I've seen 100+ processes for just 1 user. So far it only occurs for 1 user, other users have just 1 imap process. I now the user is using thunderbird and 2 mailclients are logged in at the same time (one workstation and one laptop).

[Dovecot] auth issues on centos5 with ldap backend
by Jurvis LaSalle 13 Jun '08

13 Jun '08

Hi, We've had some issues with auth. /var/log/secure is full of 1000s of these lines: Jun 4 19:12:08 khan dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser= rhost=127.0.0.1 user=user123 Users can usually login OK with their ldap credentials, but occasionally logins slow to a crawl if not outright fail, esp people checking mail through Squirrelmail. Things get better after a dovecot restart. Googling around, I thought if we switched the order or disabled the second passdb we had configured for our dovecotadmin account, these failures would go away but that did not happen. Any thoughts or additional info I can provide? Pardon the unusual install prefix. We're trying to keep the source install separated from the ancient dovecot rpm shipped in rhel5.

[Dovecot] Antispam plugin custom behavior?
by Kyle Wheeler 12 Jun '08

12 Jun '08

Hello, I currently have a setup on my system with what I call "magic folders" to enable spam filter training. Here's how it works: 1. If you have a false-negative, put the spam into the Spam.Report folder 2. If you have a false-positive (which has all kinds of ugly spamassassin protective markup in it), put the message into the Spam.NotSpam folder Currently what happens is that a cron job comes along every five minutes and processes the messages in those folders. In the case of the NotSpam folder, it strips the message of the spamassassin markup, retrains the bayesian net, and redelivers the message (e.g. via deliver). In the case of the Report folder, the message is used to train the bayesian net (among other things) and then deleted. I'd love to be able to trigger these actions when the mail is moved, rather than have a cron job inspecting the mailboxes. I looked into the antispam plugin (http://johannes.sipsolutions.net/Projects/dovecot-antispam) which seems nice but doesn't appear sufficiently generic for my needs. What would really work is if I could get it set up such that putting a message into either of those directories is turned into piping the message to a script of my choosing (a different one for each folder). Does anyone know a good way of getting my own custom behavior in here, or is my cronjob setup probably the best way? ~Kyle -- The optimist thinks this is the best of all possible worlds. The pessimist fears it is true. -- J. Robert Oppenheimer

[Dovecot] quota-rewrite patch & userdb quota overriding

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've spent the past couple of hours trying to figure this out by checking the wiki and googling, but haven't come up with anything that works yet. I just installed dovecot 1.0.14 with the quota-rewrite (1.09) patch and i'm trying to get the quota overridden via a passwd-file type userdb. I had 1.0.13 without the new quota style patched in working but having trouble figuring this out. any help would be appreciated. prior to the quota-rewrite patch (which i installed with the hopes of using quota_warn feature) i was able to put the following line into my passwd-file userdb and it was working: alan:*:1000:1000::/home/alan::userdb_quota=maildir:storeage=2048000:ignore=Sent (which is what I wanted) but now with the new quota definition style, I'm not sure what I need to define the extra fields as. here is dovecot -n: # 1.0.14: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap imaps managesieve ssl_cert_file: /etc/pki/tls/certs/dovecot.pem ssl_key_file: /etc/pki/tls/private/dovecot.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(managesieve): no verbose_proctitle: yes mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(managesieve): ~/.dovecot.sieve auth default: ~ passdb: ~ driver: pam ~ userdb: ~ driver: passwd-file ~ args: /usr/local/etc/dovecot.passwd ~ userdb: ~ driver: passwd ~ socket: ~ type: listen ~ master: ~ path: /var/run/dovecot/auth-master ~ mode: 384 ~ user: dovecot ~ group: dovecot plugin: ~ quota_rule: *:storage=1G ~ quota_rule2: Trash:storage=100M thanks, alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhPd+cACgkQE2gsBSKjZHQNMACghSk7awVX1Aj5HVeo0KjRxyZc lT0AoLJA00SiYiefi2wNrAOt7L6N5eg4 =mA8L -----END PGP SIGNATURE-----

[Dovecot] Wrong message information
by Anders 12 Jun '08

12 Jun '08

We have a few users that every so often get empty data in their message overview. From and subject are empty, and the date is 1-Jan-1970. When opening the message in full view, all things are fine. Also, the data in the actual maildir file is fine. It looks a lot like the issue described here: http://dovecot.org/list/dovecot/2008-March/029282.html The server is Linux, ext3, no NFS, and Dovecot 1.1.rc4. The few clients that have had this problem so far have been Outlook Express. What can be done to debug this? Thanks, Anders.

[Dovecot] Mutually exclusive Exim setup instructions

The correct way has to be one or the other: http://wiki.dovecot.org/LDA/Exim are mutually exclusive with http://wiki.dovecot.org/HowTo/DebianStable It appears that exim can either call dovecot's LDA or make the delivery itself. There may be good reasons to do it one way or the other. ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] Dovecot 1.1 rc9 compilation warnings
by Chris Wakelin 11 Jun '08

11 Jun '08

I've tried compiling 1.1.rc9 on everything to hand and I get various compilation warnings (but the compilation finishes). I don't know whether any of them are worth tracking down?

[Dovecot] Lucene index not updated when one saves a message from one folder to the other
by Asheesh Laroia 11 Jun '08

11 Jun '08

I'm running 1.1 rc8, and I enabled the Lucene indexes. I find that if a bunch of messages arrive in INBOX and I then move them to archive, the next time I do an X-TEXT-FAST search, Dovecot has to re-index the mails that I think it had indexed when they were in INBOX. This seems silly, since Dovecot was the one copying them (and then deleting, since that's what I mean by move). Will this change? -- Asheesh. -- Elliptic paraboloids for sale.

[Dovecot] Auto creating client folders on the IMAP server after installing client.
by Radio Tron 11 Jun '08

11 Jun '08

Hello, could someone help. I have installed Dovecot+SSL+TLS+Thunderbird and all is well except one thing. After installing TBird and adding the required data (smtp server and auth info, imap/pop server and auth info) I am able to view mail in my TBird Inbox BUT Trash and Sent don't work - it pops up saying folder doesn't exist on the server - can't the darn thing, auto create a folder on the server instead of cribbing to me??? Is there a painless (automatic way) to auto create client directories on the Dovecot server (in the users home dir on the server - i am using maildir/). I don't want to maintain a list of clients(TBird, outlook, eudora..) with their directory structure and then remember what user has what clients installed and Gahhh! How do i do this?? Is this explained/documented somewhere in simple language(for a newbie - I'm struggling through the RFC's but they are awfully obscure and don't seem to answer my question directly)? I've also googled but that's worse. Thank you for your patience and time. I'd like to add that I plan to sync GMail, Dovecot and a multitude-of-stupid-clients in some mysterious way so any advice in advance is more than welcome.

[Dovecot] Multiple SSL certificates with dovecot.
by Andre Rodier 10 Jun '08

10 Jun '08

Hello all, By advance, I hope you'll excuse my probably not perfect English, which is not my mother tongue. I have always appreciated dovecot for this simplicity to setup and lightweight, but today, after many installations, I cannot find how to setup dovecot for my configuration. - I use only IMAPS to retrieve the mails. - I manage two domain names - I use CA-Cert certificates So,the question is : how to setup dovecot to select the appropriate certificate, according to the domain name I use when I retrieve mails using the IMAPS protocol ? Thanks. Andre Rodier.

[Dovecot] inetd & corrupt environment
by Gelu G. Lupas 09 Jun '08

09 Jun '08

Hello. I'm having the following problem with dovecot 1.0.12 and above, on a FreeBSD 7.0 system - I'm trying to run pop3-login from inetd and I keep getting this error after authentication: May 25 09:46:19 charlie dovecot: POP3(gelu): /libexec/ld-elf.so.1: environment corrupt; missing value for no-nuls oe-ns-eoh The problem persists if I uncomment the lines with no-nuls oe-ns-eoh in dovecot.conf. I've also tried running pop3-login from tcpserver/ucspi-tcp and I still get the same error. Version 1.0.1 works fine on a similar setup. Please reply if you have any idea regarding a fix for this error. I need to run dovecot under a tcp wrapper of some kind (preferably inetd) as the standalone daemon doesn't allow any method to restrict access by IP. The allow_nets extra field doesn't help much as I'm using PAM and do not want to maintain yet another passdb. Restricting access via firewall rules is not an option. Until I find a way to restrict access by IP address, dovecot will only listen on the private IP address (192.168.100.1). My dovecot configuration follows: # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: pop3 listen: 192.168.100.1 ssl_cipher_list: ALL:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login login_greeting: login_process_size: 32 login_max_processes_count: 32 login_max_connections: 128 max_mail_processes: 128 verbose_proctitle: yes first_valid_uid: 1000 mail_privileged_group: mail mail_location: mbox:~/Mail/:INBOX=/var/mail/%u mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login process_size: 64 passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ---------------------------------------------------------------------- Finally - A spam blocker that actually works. http://www.bluebottle.com/tag/4

[Dovecot] EXPUNGE delay
by Eugene 09 Jun '08

09 Jun '08

Hi people! I just switched one of my servers from Courier to Dovecot. Planned to do it anyway but had to do it faster after the discovery that courier [the version I had installed, at least] returns malformed headers for a few messages, causing Outlook Express to completely ignore them. Curiously, they were visible in Squirrelmail and Nokia Series60 e-mail client. Overal I am quite happy but have one little problem. More often than not, I have to press 'Purge' button two or more times in order to actually remove the deleted messages. The fragment of Outlook's IMAP log is below. Interestingly, Dovecot 1.0.7 (on another server) does not have such problem.

Happened only when messages weren't saved via Dovecot (deliver or IMAP). - Several bugfixes to handling sort indexes - deliver: Boolean settings that were supposed to default to "yes" were set to "no" unless explicitly defined in dovecot.conf: dotlock_use_excl, maildir_copy_with_hardlinks, mbox_dirty_syncs, mbox_lazy_writes.

[Dovecot] question: auth_bind and userdb
by Matthias Šubik 07 Jun '08

07 Jun '08

Hi, this is my first post to the list, I'm not a member, please cc me directly. I'm converting from courier imap, and want to bring a special problem to your attention: I would like to use auth_bind and prefetch, b/c due to data security restriction the user information is only visible to the user himself. From http://wiki.dovecot.org/AuthDatabase/LDAP I found out that pass_attrs only works if no userdn template is set. But when unsetting userdn, dovecot-auth still tries to find the information from pass_attrs before binding. I'm no coding expert so here is my question: would it be possible to make pass_attrs work with userdn? If yes, even prefetch would work. right now, when using userdn, pass_attrs is ignored, but also userdb and user_attrs is impossible for me, because it is done anonymously, it can't reuse the bind from passdb, and can't construct a bind as passdb could. for now I defined a dummy user in ldap, but that's not the ideal solution, since then this dummy user has access to all usernames, uids, uidNumbers and gidNumbers. thank you for your attention best regards matthias subik ps: is there a list of all keywords and parameters?

[Dovecot] quotactl bug?
by JOHN ROMAN 05 Jun '08

05 Jun '08

more on the strange quota error....this is in BSD, with quotas referenced on an NFS, and users provided by YP/NIS quotactl(Q_GETQUOTA, /.amd_mnt/crock/vol/v_user1/jdoe) failed: Operation not supported this looks strange to me, as the specification for quotactl states the function Q_GETQUOTA: Q_GETQUOTA Get disk quota limits and current usage for the user or group (as determined by the command type) with identifier id. The addr argument is a pointer to a struct dqblk structure (defined in <ufs/ufs/quota.h>). this directory path is not a valid UID...rather, its my user home directory path!

[Dovecot] v1.1.rc8 released
by Timo Sirainen 05 Jun '08

05 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz.sig I then decided to add the deliver -c feature to this release. Seems to work in my tests, but who knows if it breaks something.. Although most of the code is called only if -c parameter is given. Anyway we really should have a comprehensive test suite written some day (yes, help is really wanted for this :). So let's hope this is the last RC release. If there aren't any major problems I'll release v1.1.0 in a couple of weeks. I'll also try to merge all my different development trees into a single v1.2 code tree within a few weeks. v1.2.0 will probably be released this summer as well, since it mainly has new features that don't change existing code all that much (CONDSTORE is a bit invasive though). + deliver: Added -c parameter to provide path to delivered mail. This allows maildir to save identical mails to multiple recipients using hard links. - rc6/rc7 broke POP3 with non-Maildir formats - mbox: Saving a message without a body or the end-of-headers line could have caused an assert-crash later. - Several dbox fixes

[Dovecot] Get the size of a maildir
by Nicolas Letellier 05 Jun '08

05 Jun '08

Hello. I would like to know it a 'proper' solution exist to get the size (in MB) of a maildir. Actually, to get it, I do a 'du -sh' but I'm not sure it is a good solution. And it does not return the same value than imap-quota. Is there a command, a tool, in Dovecot to get it? There is the maildirsize but it's very difficult to get the value with a script shell and with this file. Thanks for your help. Best regards, -- - Nicolas.

i have a dovecot setup that uses an nfs backend to store maildir data. i want to enforce fs quotas, but whenever theyre selected and i attempt to query them from thunderbird...this appears in the log quotactl(Q_GETQUOTA, /.amd_mnt/crock/vol/v_user1/jdoe) failed: Operation not supported i also occasionally see this. dovecot: statfs(/users/jdoe/Maildir) failed: Permission denied i can manually query quotas from a terminal on the mail system though.

[Dovecot] FreeBSD port for 1.1, some bits more...
by Geoffroy DESVERNAY 04 Jun '08

04 Jun '08

I did (re-)compile dovecot (1.1rc8) today, with managesieve (0.10.2) and sieve-plugin (1.1.5). I did modify the existing dovecot-devel port, adding managesieve patch as an OPTION, and I added a 'dovecot-managesieve-devel' port, and a 'dovecot-sieve-devel' one to be complete... Not sure everything is very complete, but at least it works for me=E2=84=A2= , and if it can help anybody to save some time... The tree ports are there: http://dgeo.perso.ec-marseille.fr/dovecot Not sure I used the very good way of building FreeBSD ports...

[Dovecot] Re maintenance of the dovecot-uidlist files
by Dann Daggett 04 Jun '08

04 Jun '08

Greetings all, I am new to dovecot, using ver 1.0.13 and IMAP with ~/Maildir delivery. I have noticed that the entries in the dovecot-uidlist files don't seem to get updated when an email is deleted or moved to .Trash. It appears that this list list would just keep growing over time, being full of no longer used filenames, and must tend to increase its processing overhead. I have also noticed that if I manually delete that file and the 3 other dovecot* files, that it gets rebuilt with only what's present. Is there provision in the dovecot code to automatically clean this up periodically? If so, are there any configuration params for it? If not, what is the preferred method for maintenance in this regard? Thank you, Dan

[Dovecot] Error using antispam plugin
by Juan Asensio Sánchez 03 Jun '08

Hi When activating antispam plugin in imap protocol, when sending an email, Evolution/Thunderbirdkeeps infinitely "Sending authentication information", and Dovecor logs shows "dovecot: May 28 10:14:35 Error: child 6910 (imap) killed with signal 11"; lots of empty folders in /tmp are created with names like "antispam-mail-ZvyWeZ". I am using Dovecot1.1 rc15 compiled from Debian source repositories (http://xi.rename-it.nl/debian/) and last version of antispam plugin, obtained with git. Any idea or help to debug? Thanks.

[Dovecot] v1.0.14 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz.sig Since v1.1.0 release is getting near, this could well be the last v1.0 release. I'll still fix important bugs, but if the bugfix is large or affects only few people it'll probably get fixed only in v1.1 releases. * mbox: Enable mail_privileged_group while creating INBOX. - IMAP: Fixed a rare crash in FETCH BODY/BODYSTRUCTURE - IMAP: If mailbox is selected with EXAMINE, ignore flag changes - proxy: Login success reply was sent in two IP packets, which confused some IMAP/POP3 clients - ACL plugin leaked memory a bit - dovecot-auth: allow_nets setting with network masks didn't work correctly with big endian machines.

03 Jun '08

Hi, after having moved a big mail archive to IMAP, I've now got the following problem: The MUA asks to send an MDN on all those old messages that contain the 'Disposition-Notification-To' header when opened. I'd like to set the $MDNSent flag on those (>10000 in a deeply nested directory structure) mails. After having read http://wiki.dovecot.org/MailboxFormat/Maildir I wrote a script that changed the filename of mails in all directories that contained the header, so that the filename contained a 'b' in the last part of the filename (after the comma), because I found '1 $MDNSent' in Maildir/dovecot-keywords. I then discovered that there can be a 'dovecot-keywords' file in each directory, and all of those files can have different flags in different order. Do I really need to write a script that evaluates each dovecot-keywords file, figures out which letter corresponds to the flag and rename the files (per directory) accordingly? Isn't there a more simple way?

[Dovecot] spamassassin, postfix with dovecot lda?
by George Mamalakis 03 Jun '08

03 Jun '08

Hi all, I am trying to setup a mail server using postfix (virtual_mailboxes), spamassassin and dovecot, along with SQL where appropriate. From my research so far I realized that, for several reasons, it is required for me to use dovecot LDA instead of maildrop, local, procmail or other alternatives. My configuration was working flawlessly, until spamassassin per-user configuration came to play. If I just wanted an MTA anti-spam gateway, I could directly call spamassassin via master.cf, or through some helper "content-filter-application" (like amavis or amavisd-new), and everything would work just fine (I tried and tested many such configurations with success). But when antispam per user preferences became my concern (Bayesian filters and classifier), I realized that spamd should be called by the LDA. With procmail this was a trivial issue, with dovecot-lda I was unable to find any solution on the web or other documentation. So my question is as follows: Is there a way to call spamc from dovecot-LDA (and/or dovecot-sieve), or is there an alternate way to do this for a site with virtual mailboxes configured with dovecot-lda? Thank you all in advance, regards, -- George Mamalakis IT Officer, Department of Electrical and Computer Engineering, Aristotle Univ. of Thessaloniki, Greece

[Dovecot] v1.1.rc6 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz.sig This is it. The first v1.1 release that actually deserves the "release candidate" name. It contains everything I require from v1.1.0 release. There are two bugs left that I'd like to get fixed, but they won't block v1.1.0 release: * index_mailbox_set_recent_uid() assert (reported by Diego Liziero) * Maildir not always finding new messages and returning them as empty (reported by Anders). The major change in v1.1.rc6 release is the SORT indexing half-rewrite. I hadn't much stress tested that code before, and once I started I just kept finding more and more weird bugs and it became extremely difficult to figure out how to fix them, so I finally decided to just redesign how it's supposed to work and then implemented that. The resulting sort code is a lot cleaner and it should also perform better (although it could still be improved a bit: the basic binary searching could be replaced with one that first binary searches between already-looked-up sort-strings and only after that binary searches the resulting space which requires slower sort-string lookups). Hopefully there are also no stupid bugs left like returning messages in wrong sort order. :) I've been wasting time this past week getting new stuff for my new apartment, but that's nearly done now. I think (hope) I'm going to be more productive in here, there are less neighbours behind walls/floors (just 1), so less potential for annoying noises. :) Thinking also seems to work better when there's more space to walk around. And finally, the changes since v1.1.rc5: * Index file format changed a bit. If an older Dovecot v1.1 reads index files updated by rc6+, they may give "Invalid header record size" or "ext reset: invalid record size" warnings. v1.0 won't give these errors. * IMAP: LIST .. RETURN (X-STATUS) command return now LIST entries before STATUS entries. * zlib plugin: Uncompress if the message begins with zlib header instead of looking at the 'Z' flag. This fixes copying with hard links. Based on a patch by Richard Platel. + IMAP: SORT index handling code was half-rewritten to fix several bugs when multiple sessions were sorting at the same time. The new code is hopefully also faster. + Maildir: If POP3 UIDL extra field is found from dovecot-uidlist, it's used instead of the default UIDL format (or X-UIDL: header). This allows easily preserving UIDLs when migrating from other POP3 servers. Patch by Nicholas Von Hollen @ Mailtrust. + Maildir: ,W=<vsize> is now always added to maildir filenames + deliver: Avoid reading dovecot-uidlist's contents if possible. + Added %T modifier = Trim whitespace from end of string - IMAP: Fixed some bugs in LIST-EXTENDED implementation. - IMAP: If client tries to change the selected mailbox state while another command is still running, wait until the command is finished. This fixes some crashes and other unwanted behavior. - allow_nets userdb setting was broken with big endian CPUs

[Dovecot] overview of patches used in Fedora
by Dan Horák 03 Jun '08

03 Jun '08

Hi, I have gone through the patches that are used in the Fedora package and probably only the "mkcert-permissions" [1] can be considered to be included upstream. It is dated into package version 1.0-0.beta2.3, but I cannot find any particular reason for the inclusion (like a bug in bugzilla, etc.). Some (winbind support, quota warnings) were obsoleted by dovecot 1.1, two are used for distro specific settings. So the only real patch that remains is the "pam_setcred" [2] patch that fixes https://bugzilla.redhat.com/show_bug.cgi?id=146198 Current state of the package for Fedora is at http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/ Dan [1] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.beta2-m… [2] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.rc2-pam… -- Fedora and Red Hat package maintainer

[Dovecot] Unsuccessful POP sessions on dovecot-1.0.3-13_60
by Patrick Ben Koetter 03 Jun '08

03 Jun '08

A Client runs a RAS network. Users access mailboxes using Outlook Express. The server runs dovecot-1.0.3-13_60. Almost a week ago users began to report that they can't retrieve their mail. The session starts, they seem to retrieve messages, but then the client reports a problem and the session is terminated. Here's what I have in the log: May 28 08:56:46 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 08:59:00 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 08:59:29 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:03:49 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:04:24 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:12:11 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:14:32 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:17:10 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:17:52 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:20:27 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:23:23 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:30:05 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 What I see is that the client seems to try to retrieve the same mails (retr=5/448621) over and over again. If they login using IMAP they don't experience any problems. Any idea what this could be? Rumor has it it's a know problem with Outlook Express and its POP implementation.

[Dovecot] Purging Deleted Messages
by Carlos Williams 02 Jun '08

02 Jun '08

I noticed today I checked a users mailbox with the mutt command: mutt -f /home/bob/email/ There I saw he had 100 messages that had been deleted but not yet purged from his inbox so they're still using up disk storage on my email server. My question is does Dovecot have a process to automatically delete these messages after a certain period of time? I would like to think that they don't just sit in a users mailbox for years waiting to be purged, right? Does anyone know exactly how this works? I checked my own mailbox using mutt and I see 11 messages that are deleted from my Thunderbird client but are still on the server (marked for deletion). How long do these messages stay there? -- Man your battle stations...

[Dovecot] deliver & override homedir
by arne van theemsche 02 Jun '08

02 Jun '08

Hi We're in the phase of converting our existing unix-based users to virtual users. Goal is to make mail-spool totaly independent of home-spool. For that reason, NO files can be written to home. I've solved the problem for all files, except for .dovecot.lda-dupes. I can see in duplicate.c #define DUPLICATE_PATH "~/.dovecot.lda-dupes" I thought being clever and override in the userdb passwd following args = home=/var/spool/mail/%1n/%2n/%n but deliver totaly ignores that. does anybody has tips? kind regards Arne

[Dovecot] deliver saving mails with hard linking
by Timo Sirainen 02 Jun '08

02 Jun '08

http://dovecot.org/tmp/deliver-multiple.diff for Dovecot v1.1 implements -p <path> parameter for deliver, which reads the input mail from the specified path instead of stdin. With maildir and hardlink copying enabled, it also tries to hard link the file to destination instead of copying it. So to get the same mail delivered to multiple recipients using hard links, you'd have to write a small wrapper script that stored the mail temporarily somewhere and then called deliver for each recipient using the -p parameter. Any thoughts on if this should go to v1.1 like this? Some problems: - If you're not using a single UID/GID you probably have to make the file world-readable. - A wrapper script is kind of ugly, so it would be nice if deliver took a list of all recipients as input. But the deliver code is currently ugly enough that this would require larger changes. - Am I forgetting something?..

Right. This isn't implemented yet. Also I don't think it should rely on Message-ID: header proving the uniqueness. There are two ways this can be implemented reliably: 1) If the message is sent to multiple recipients using same RCPT TO command, all the recipients could be given to deliver as parameters, and deliver would know that it's the same message and they could be hard linked. 2) Keep some kind of a hash database where hash is e.g. SHA1 sum of the entire message. All messages could be then stored in some global directory and hard linked from there to users' mailboxes. When receiving a new message using an existing hash, it could still compare byte-by-byte the files to make sure that it's not a hash collision before hard linking the file. 1) probably wouldn't be too difficult to implement and probably would solve your problem (assuming the problem is that people are mailing 100MB attachments to everyone inside a company). But I don't think I have time to do it myself..

[Dovecot] Dovecot hard link problem
by 도원철 01 Jun '08

01 Jun '08

My company recently changed mail server from cyrus to dovecot. The problem is that dovecot does not support hard links for message files with same message ID. I turned on the ‘maildir_copy_with_hardlinks’ option in dovecot.conf, but it does not seems to have relation to this problem, am I misunderstood? Hard links are created when move or copy messages from one folder to other folder, but when deliver creates messages this option does not works. Our mail storage will be exhausted in few days. If you have some idea to solve this problem, please please help me. Or If you fix this problem, I will happily pay for it at reasonable cost. I installed dovecot 1.0.13 and postfix 2.5.1.

Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth.

[Dovecot] fetchmail on demand
by Graeme Vetterlein 31 May '08

31 May '08

I hoping this is an RTFM ... and somebody can point me at the correct 'FM' :-) I've just spent a while setting my new Debian , allways-on box in what I suspect is a generally useful configuration. I have fetchmail(1) collect mail from many mailboxes via pop3. I store these mails in different mboxs according to rules in procmail(1) I then offer these out to the household via imap in dovecot(1) . I have fetchmail(1) set to poll the ISPs every 5 minutes, this seems to work fine, but there are two issues: 1: The constant polling keeps the disk spinning for no good reason (most of the time) 2: If I check my mail via a mail reader using imap to the local mboxes ...there could be mail sitting on the ISP servers I don't see (for 5 mins) Now what would be much nicer, would simply be to have dovecot(1) issue the fetchmail(1) command whenever it it got an imap request. I general what I guess I would like is: "When a request comes in (via imap) fork off a command who's name is given in the conf file. ... imap_pre_cmd="xxx" -- Graeme

[Dovecot] Sieve Editheader Extension?
by Michael K Sanders 31 May '08

31 May '08

I've done extensive searches, and there is virtually no information about actual implementations of the draft Sieve Editheader Extension (which provides 'addheader' and 'deleteheader' actions): http://www.ietf.org/internet-drafts/draft-ietf-sieve-editheader-11.txt Is anyone currently working on this for Dovecot Sieve? If not, are there any plans to do so? And before I start digging through the source, is the architecture amenable to this functionality? Thanks, :: Mike ::

[Dovecot] Web-based shared calendar synchronizable with Outlook
by Samuel HAMEAU 30 May '08

30 May '08

Hi, I know this request is a a little off-topic but may be interesting for dovecot users (at least i hope!) Does anybody has already had an experience with a calendar sharing solution including a webcalendar and an outlook connector, "compatible" with dovecot ? Today, there are many projects aiming to be a "M$ Exchange Killer" (such as Zimbra, OBM, open-exchange, etc) but they offers a global package with MTA and imap server included. I saw the page about BynariConnector (http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do not provide a webmail :( I'm afraid What I am looking for is a shared agenda solution providing a webcalendar, an outlook connector and eventually a pda connector, using (or not) dovecot, and a corporate ldap server... What are you guys using ? sam

[Dovecot] no bookeeping using public folders
by Claude Frantz 30 May '08

30 May '08

Using dovecot 1.0.10. In the config: namespace public { separator = / hidden = no prefix = Flock/ location = maildir:/home/baratin/PublicMaildir:CONTROL=~/Maildir/control/Flock:INDEX=/var/dovecot/index/%u/Flock } This should be a public mail folder owned by "baratin", "read only" for all other users. Every user has his/her own control and index area related to this public folder. I have verified, they are owner and "group" of the respective control and index area. The problem, while using Thunderbird: The "read only" user can delete messages or mark then read. But after a new session, all the messages are still "new". Of course, only "baratin" is the owner. The problem, while using mutt and IMAP: mutt refuse to change any flag because the folder is "read only". Of course, this is correct. My question: Why is no bookkeeping maintained for "other" users, although every one has his/her own control and index structure ? Thanks a lot ! Claude

[Dovecot] Problem deleting folders with Thunderbird?

30 May '08

I am running Thunderbird 2.0.0.14 on Windows XP. When I try to delete one of the folders I get a dialog with the following "The current command did not succeed. The mail server responded: Target mailbox doesn't allow inferior mailboxes." I am running dovecot version 1.0.13-6.fc8 under Fedora 8. The output of dovecot -n is below; [root@www knute]# dovecot -n # 1.0.13: /etc/dovecot.conf protocols: imaps pop3s disable_plaintext_auth: yes 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_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 Is there something to be configured to allow mail box deletion? I know there was a similar discussion this week about users deleting their mailboxes accidentally. Are folders within folders allowed by dovecot?
