[Dovecot] Dovecot+PostfixAdmin+PostgreSQL on FreeBSD 7
by Erdenebat Guntomor 22 Oct '08

22 Oct '08

Hi dear All, Currently I'm configuring Dovecot+PostfixAdmin+PostgreSQL on FreeBSD 7 Stable and using Dovecot v1.1.3. I hope I've configured everything. But when I run /usr/local/etc/rc.d/dovecot start then dovecot doesn't seems to running. /var/log/maillog is only showing following.

[Dovecot] Permission issues with subscriptions
by Eric A. Bonney 22 Oct '08

22 Oct '08

I am having some permission issues with my setup and I can't see where to make the change in the configuration files. My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder. running dovecot -n produces the following: # 1.0.10: /etc/dovecot/dovecot.conf listen: [::] login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 default_mail_env: maildir:/mnt/hd4/MailBoxes/%d/%n mail_location: maildir:/mnt/hd4/MailBoxes/%d/%n umask: 511 auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch I am guessing that Dovecot is the actual process that is creating the folders on the IMAP server, so where inside the configuration file do I set the permissions for the new folders along with the user and groups? Thanks, -Eric

[Dovecot] Proxying pop3 sessions into an imap one.
by Diego Liziero 22 Oct '08

22 Oct '08

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really true, or if it's worth keeping like a funny signature: "multiple imap sessions are possible. When an imap session is active, no pop3 connections are possible on the same account; when no imap connection is active, only one pop3 connection at a time is possible on the same account. This is a limitation of the pop3 protocol." - 2 - A software written to deal with certified mails that supports only pop3 used by many people on the same account, (and the same account is used also by multiple imap mail readers). Regards, Diego.

[Dovecot] 1.2: Bug in listing of shared mailboxes with dot in user id
by Sascha Wilde 21 Oct '08

21 Oct '08

In dovecot 1.2 I can create a shared name space like this: namespace shared { separator = / prefix = users/%%u/ location = Maildir:/PATH/TO/spool/%%u/maildir:INDEX=/PATH/TO/spool/%u/maildir/shared_idx subscriptions = no } now, when I subscribe to a shared mailbox of another user with an dot in the users id, like: users/2(a)example.com/INBOX/foo and I list my subscribed mailboxes I get: l001 lsub "" "*" * LSUB () "/" "users/2@example/com/INBOX/foo" as you can see the dot in the user-id got normalized to the hierarchy seperator `/' -- which of cause is wrong. ;-) cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Reporting NFS quotas via IMAP
by Edgar Fuß 21 Oct '08

21 Oct '08

I'm confident that the question has been asked before, but I can't remember the answer. I have -- dovecot 1.1.2 -- Mail storage (maildir format) on NFS -- Quotas on that file system -- A working rquotad -- mail_plugins = quota imap_quota in the protocol imap section -- quota=fs in the plugin section I get (using Apple Mail as a client) -- Notification that the account supports quotas -- No information about the size of the quota nor the usage I probably do something stupidly wrong. The WIKI tells me that fs quota support RPC (i.e., rquotad), so I'd expect my client to report the quota to me. Using quota(1) on the mail server works as expected.

[Dovecot] Using allow_nets
by Guy 20 Oct '08

20 Oct '08

Hi, I'm wanting to implement allow_nets so that some users can be limited to only use webmail while others can use client or webmail access. Adding the sql to pull a list of IPs/ranges for webmail only users was easy enough. For the users that are allowed to access from anywhere, do I need to specify 0.0.0.0/0 or something or can I just let the sql query return a blank field? Thanks Guy -- Don't just do something...sit there!

[Dovecot] v1.1.5 release candidate
by Timo Sirainen 20 Oct '08

20 Oct '08

http://dovecot.org/tmp/dovecot-1.1.5-rc.tar.gz I thought about making v1.1.5 release today, but then thought maybe I'll make an RC instead since I did quite a lot of changes this weekend. So please try and see if there are any bugs left. I'll make the final release in a couple of days. The largest changes since v1.1.4: + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Fixed compiling with OpenBSD

[Dovecot] NFS quota: hard or soft
by Edgar Fuß 20 Oct '08

20 Oct '08

Yes. I could spend more time testing this myself or examining the code. It looks to me that, with fs quota, dovecot refuses to store a mail (e.g. when the client moves a mail from one IMAP folder to another) if the user is beyond his soft limit. Is this correct/intended? Knowing nothing about the IMAP Quota extension, I would have expected that being in grace was OK. At least, this is what would happen if dovecot wasn't quota aware and the file system would enforce the limits.

[Dovecot] Sendmail and deliver LDA exits with EX_TEMPFAIL on overquota
by Sotiris Tsimbonis 20 Oct '08

20 Oct '08

Hi all, I have setup dovecot 1.1.4 and sendmail 8.14.3 with dovecot LDA on linux (RHEL5 on x86_64). I have deliberately set a very low quota (4MB) on a test account, while the actual disk usage is 5MB at the moment, in order to test overquota behaviour.. When I send an email to this account, sendmail accepts the email and tries to deliver it. Deliver fails to save in INBOX and returns an error, but the email stays in sendmail's queue.. Any suggestions on how to avoid this and produce a 5xx error for overquota users before accepting the email would be greatly appreciated..

[Dovecot] workaround for shared maildirs
by Giuliano Gavazzi 19 Oct '08

19 Oct '08

Hello, this is my first post to the list. I have several mailservers running courier-imap, but am planning to convert one (and maybe more) to dovecot 1.1.4. In the process I am also looking to finally implement shared maildirs. As it is well known some clients (notable Apple's Mail) have problems in showing shared folders if the correct private namespace (INBOX) is set in the client, as only folders beneath the INBOX root are displayed. I have seen some solutions proposed, but none satisfactory. As the problem stems in the invisibility of secondary namespaces from Mail.app, I though that tricking the namespace prefix to push the shared mailboxes inside the private INBOX namespace could be a solution and tried the following: namespace public { separator = . prefix = INBOX.Public. inbox = no location = maildir:/SharedMaildirs/Public:CONTROL=~/Maildir/ control/Public:INDEX=~/Maildir/index/Public hidden = yes list = yes subscriptions = yes } note the bogus INBOX.Public prefix. Note also that CONTROL might be better not set as this is a Maildir (see Keyword sharing in http://wiki.dovecot.org/SharedMailboxes) Initially I had defined an additional public namespace with the same maildir and a normal prefix, but this seems not necessary. Well, after some tests from Thunderbird, Mail and cone (yes, the courier UA) I can say it works . Still have to check Outlook and Opera, but this is encouraging. As the public namespace Public is actually contained inside the private (INBOX), as if it was a private mailbox (with no messages) called Public, it is actually possible to create such a mailbox inside INBOX and end up with a private mailbox called Public containing private messages AND public mailboxes... Any mailbox that a user creats inside Public instead, will end up being a public mailbox as expected. Thanks or any comments. Giuliano

[Dovecot] regarding dovecot.index.cache
by Dhaval Thakar 19 Oct '08

Hi, This is regarding updating dovecot.index.cache. I have few backup ids configured. these are used only when old mail needs to be retrieved. usually these mailboxes contains more then 9,000 mails. while login to webmail, imap consumption is high, which creates performance related issues for regular mailboxes. to resolve this i have to move heavy mailbox to dedicated server. before doing that, I wanted to confirm if there any way to update dovecot.index.cache even if user is not checking his / her mails. kindly confirm, & provide direction to implement same.

[Dovecot] Dovecot 1.1.4 / Maildir++ quota and move to trash
by Xavier Beaudouin 18 Oct '08

Hello, Seems there is some nasty problems with Dovecot 1.1.4... We use Maildir++ quota, and when moving mail to Trash, Dovecot just drop the connection... when the maildir is overquota. Is there any way to avoid that and just move the mail to the trash allowing user to expunge their mail easily without calling support to do rm -rf Maildir/cur ? Thanks, /Xavier

Re: [Dovecot] Corrupted transaction log file / record size too small
by Steven Winikoff 18 Oct '08

18 Oct '08

>> I've been working around the problem by deleting the contents of >> ~user/.imap for affected users, but I'd really prefer to fix it >> properly. :-) Any suggestions would be gratefully received. > >I think this should get fixed by itself? Although the first login fails, >the next one should succeed. Yes, that's right. I didn't realize it at first, because we were also seeing other problems (eg assertion failure at line 39 of index-sync.c) which did require the index to be deleted. I've since made the following changes: 1) commented out the assertion at line 39 of index-sync.c (as per http://www.nabble.com/dovecot-panic-after-upgrade-1.0.15-to-1.1.2-td1909850…) 2) recompiled dovecot without optimization (ie, gcc -O0 instead of -O2) (as per http://www.mail-archive.com/dovecot@dovecot.org/msg12936.html) 3) reverted to using flock for file locking instead of fcntl (we'd been using flock with dovecot 1.0.10; 1.1.3 used fcntl by default in a couple of places, so I changed it back to see what would happen) After this, we've seen fewer problems, but there are still the occasional ones: - the original corrupted transaction log error which prompted this thread - we still see the occasional assertion failure at line 1091 of index-mail.c; this is the one that I'd hoped to solve by recompiling without optimization, but at least it seems to be happening less frequently than before - this doesn't happen often, but once in a while we see assertion failures at line 163 of src/pop3-login/client-authenticate.c or line 200 of src/imap-login/client-authenticate.c >Can you reproduce this by running imaptest (on a test account)? >http://imapwiki.org/ImapTest Actually this and your other suggestions may not be necessary; I think I just realized what's been going on. I missed this originally, but on reflection I notice in the logs that every time the "record size too small" error appears, inevitably the user involved is over disk quota and out of grace period. For example, Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Corrupted transaction log file /home/XXXX/mail/.imap/sent-mail/dovecot.index.log: record size too small (type=0xcd91, offset=8180, size=0) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: fscking index file (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Transaction log got desynced for index (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Disconnected: IMAP session state is inconsistent, please relogin. bytes=169/1848 Oct 3 17:52:22 alcor dovecot: imap-login: Login: [14998], XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: wrapper[15023]: imap, XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: imap[15023] XXXX, NNN.NNN.NN.NNN: open(/home/XXXX/mail/.imap/CFI-Howe/.temp.alcor.15023.e786c194b1dcc08c) failed: Disk quota exceeded Having seen this, I went back to the saved log for September 30th (the one containing the excerpt I pasted into my original message in this thread) -- and interestingly, I found that the quota failure wasn't recorded there. I don't know what was different about that occurrence, but everything I've seen recently suggests that "record size too small" is due to interaction with the quota system. ...so this is where I admit that I have indeed read http://wiki.dovecot.org/Quota/FS; unfortunately, the only user-writable file system on this machine that doesn't have (or need to have!) disk quotas enabled is /var/tmp, which doesn't seem to be a suitable place for dovecot indexes. Under the circumstances, are you still interested in seeing ImapTest results and a backtrace? If so, should I do that before or after upgrading to 1.1.4?

[Dovecot] Request for help with new plugin
by John Lightsey 18 Oct '08

18 Oct '08

Hi there, I was having lots of trouble with the normal expire plugin so I decided to try and come up with a plugin that handles the trash directory in the same way as Courier (when the user logs out it should clean messages from the trash that have been there for more than X days.) I used the expire and trash plugins as a guide but there are probably a number of things done wrong here and I have plenty of questions. To use this you'd need to run autoreconf for the autotools scripts, compile, make, make install, then add "autoexpire" to the imap/pop3 mail_plugins lists and "autoexpire = Trash 7" to the plugin section. 1. Is there any documentation of how the hook system and virtual mailboxes work outside of the source code? 2. I'd like the Trash cleanup to occur at logout, but the closest I could find was mailbox close. This makes the behavior a little quirky. It seems like Dovecot closes the mailbox each time it performs an operation on it, so when the client gets a list of mail in the box it does a close and the oldest items in the returned list will actually be expunged. 3. Is SAVE_DATE the correct field to be looking for here? I want the expiration to be based on the amount of time the letter has spent in the trash folder. 4. For searching through the Trash folder, SEARCH_BEFORE doesn't seem to match up with SAVE_DATE. Is there some other way to limit the search results to the dates that will fall before a certain SAVE_DATE value? J.D.

[Dovecot] deliver not picking up INDEX setting?
by Tim Bishop 18 Oct '08

18 Oct '08

I'm using the post-login script approach to give more customisation to where our users can store their mail. It detects the location and type of the mailbox at runtime and passes it through using the environment to imapd. This works great. However, I can't seem to make deliver do the same. I pass it the same MAIL and NAMESPACE settings in the environment: MAIL=maildir:/home/cur/tdb/Maildir:INDEX=/var/state/dovecot-indexes/tdb NAMESPACE_1=maildir:/home/cur/tdb/Maildir:INDEX=/var/state/dovecot-indexes/tdb NAMESPACE_1_INBOX=1 NAMESPACE_1_LIST=1 NAMESPACE_1_PREFIX=INBOX. NAMESPACE_1_SEP=. NAMESPACE_1_SUBSCRIPTIONS=1 NAMESPACE_1_TYPE=private (plus some others set by my MTA) So INDEX appears to be set correctly. deliver does correctly pick up the mailbox location and has no trouble delivering mail, but the indexes are put in the Maildir directory and not under the indexes directory. Is it possible to make deliver respect the INDEX setting? Thanks, Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Multiple maildirs
by Vassilis Vatikiotis 17 Oct '08

17 Oct '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is is possible to specify multiple maildir location in mail_location? (default_mail_env in my case since I'm using version 1.0.rc15/debian etch). What I want to achieve is receive mail in /var/spool/mail, which is going to contain 1 Maildir per user, and have /home/%u/Maildir/ to store (move) messages from spool location. Postfix is taking care of the 1st (delivery in maildir format in spool location), and dovecot should (I want to) be able to read messages from both locations. Ideally, is something like: default_mail_env = maildir:/var/spool/mail:/home/%u/Maildir possible? thx -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFI9MEcgUWLzP4xLCERAoLKAJ4ySsAfIKDqIenmww1sTApcjikM3wCeIBA1 vO0glRfNXUtajKMaPYHM8L4= =eL+3 -----END PGP SIGNATURE-----

[Dovecot] Problem with namespaces
by Tim Bishop 16 Oct '08

16 Oct '08

[1.1.4 with http://hg.dovecot.org/dovecot-1.1/rev/b61424a50786 applied] I'm trying to use namespaces as described here for UW-IMAP compatibility: http://wiki.dovecot.org/Namespaces But I'm getting a problem with the hidden namespaces showing up in the LIST output. Here is a simplified transcript. The ~/Mail folder contains just two folders. The config given to imapd is as follows: MAIL=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1_INBOX=1 NAMESPACE_1_LIST=1 NAMESPACE_1_PREFIX= NAMESPACE_1_SEP=/ NAMESPACE_1_SUBSCRIPTIONS=1 NAMESPACE_1_TYPE=private NAMESPACE_2=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_2_HIDDEN=1 NAMESPACE_2_LIST=0 NAMESPACE_2_PREFIX=mail/ NAMESPACE_2_SEP=/ NAMESPACE_2_SUBSCRIPTIONS=0 NAMESPACE_2_TYPE=private I would expect the second namespace not to be listed. But it is: in: 2 LIST "" "*" 3 LOGOUT out: * OK [RAWLOG TIMESTAMP] 2008-10-16 15:41:40 * LIST (\NoInferiors \UnMarked) "/" "folder" * LIST (\NoInferiors \UnMarked) "/" "test" * LIST (\NoInferiors \Marked) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "mail" * LIST (\NoInferiors \UnMarked) "/" "mail/folder" * LIST (\NoInferiors \UnMarked) "/" "mail/test" 2 OK List completed. * BYE Logging out 3 OK Logout completed. That's with hidden turned on, and the list option turned off. Am I missing something with my config? Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Virtual Domains and Master Users
by Roderick A. Anderson 16 Oct '08

16 Oct '08

Can I have a master users list for each virtual domain? I'm not sure from what I read on the page: http://wiki.dovecot.org/Authentication/MasterUsers auth default { mechanisms = plain login CRAM-MD5 passdb passwd-file { args = /var/mail/vhosts/%d/passwd.masterusers master = yes pass = yes } passdb passwd-file { args = username_format=%n /var/mail/vhosts/%d/passwd } userdb passwd-file { args = username_format=%n /var/mail/vhosts/%d/passwd } ... } TIA, Rod --

[Dovecot] dovecot 1.2: dict no longer really support DICT_ITERATE_FLAG_RECURSE
by Bernhard Herzog 16 Oct '08

16 Oct '08

Hi, In dovecot 1.1, I could use DICT_ITERATE_FLAG_RECURSE when iterating over a dict to retrieve all entries that start with a given prefix. This doesn't seem to work anymore in the new dict implementation in dovecot 1.2. Looking at the SQL queries actually generated, it seems as if dovecot 1.1 used to generate queries that use pattern matching (key LIKE "my/prefix/%") whereas dovecot 1.2 does not, so it's no wonder that it doesn't work in 1.2. This probably has to do with the pattern matching for dict keys in the config file. It would be enough for my purposes at the moment -- i.e. getting the metadata plugin to work with dovecot 1.2 -- if recursion were only possible for the last of fields in the pattern.

[Dovecot] dovecot 1.1.4 maildir imap segfault in message_parse_header_next
by Diego Liziero 16 Oct '08

16 Oct '08

I've tried to stress test dovecot 1.1.4 with imaptest for days without any assertion failure or crash. Just some "got too little data" messages. So far it's the most stable 1.1.x version. Today a user got this imap segfault with vanilla 1.1.4 (I don't know if it's something you have already fixed in current tree). The user didn't complain of anything, I've just found the error in the logs and the core file. Regards, Diego. ---- Core was generated by `/usr/libexec/dovecot/imap'.

[Dovecot] deliver does not work with new shared namespaces in dovecot 1.2

Hi Timo, checking my new userdb-checkpassword back end is stumbled across the fact, that the new shared namespace definitions possible in dovecot stop deliver from working. The log says: Oct 15 14:37:43 burlywood3 <info> deliver(2(a)burlywood3.rgb)[24502]: Namespace: type=shared, prefix=users/%%u/, sep=/, inbox=no, hidden=no, list=no, subscriptions=no Oct 15 14:37:43 burlywood3 <error> deliver(2(a)burlywood3.rgb)[24502]: Namespace 'users/': shared: Shared namespace prefix contains unknown variables Oct 15 14:37:43 burlywood3 <critical> deliver(2(a)burlywood3.rgb)[24502]: Fatal: Namespace initialization failed I guess the primary (only?) case where these shared namespaces are needed for delivery is the use of sieve. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

Both are system users. Dovecot allows login in for the first user but doesn't allow login for the second user. Any help will be appreciated.

[Dovecot] Ignore prefix given by client?
by Tim Bishop 15 Oct '08

15 Oct '08

Hi all, I'm new to Dovecot, but so far I've been really impressed with what I've seen. I hope someone can help with the following question. We're migrating from a setup where some of our users use mbox with UW imap. The problem is we've never enforced a folder prefix, so some have their folders in ~/, others in ~/mail and others in ~/Mail. We've also got some users using maildir with Courier imap. I decided the easiest way to get this working transparently for the users was to use the post-login scripting approach. My script manages to locate the user's mail and sets MAIL accordingly. This all works a treat. The problem is when a user specifies their own prefix in their mail client (if it's blank there are no problems). If they have ~/Mail none of the folders show up. I've had a play with namespaces in an attempt to fix that, but it doesn't seem to be doing what I want. So my question is: is it possible for Dovecot to simply ignore the folder prefix given by the client? Thanks, Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Multiple IMAP connections.
by Roderick A. Anderson 15 Oct '08

15 Oct '08

There is a project (catmail) to build a webmail front end using the Catalyst Framework and the question came up about multiple connections per user. Specifically the question was: "The IMAP server can support multiple connections, but do you think the backend should support multiple connections for separate folders or one IMAP connection for one session?" Since my servers are too low volume to have hit any kind of resource limits, and I believe Thunderbird mostly does the "Right Thing", I'm asking how you, that have higher volume systems, would prefer connections handled. Also I believe there was a thread, or two :-), on the way some of the other webmail programs handle connections. Not good? Thanks for all insights and suggestions. Rod --

[Dovecot] Bug: MODSEQ FETCH return (?)
by Michael M. Slusarz 15 Oct '08

15 Oct '08

Hi Timo - hope things are well :) Playing around with the CONDSTORE (RFC 4551) stuff while testing the IMAP lib I am writing and I think I have found a bug in Dovecot 1.2. RFC 4551 [4] identifies the FETCH response to a MODSEQ request as follows: fetch-mod-resp = "MODSEQ" SP "(" permsg-modsequence ")" with 'permsg-modsequence' defined as: permsg-modsequence = mod-sequence-value ;; per message mod-sequence Unfortunately, Dovecot 1.2 is returning as follows: S: * 1 FETCH (UID 1 MODSEQ 3 FLAGS (\Flagged \Deleted \Recent)) Where, under the RFC, I believe it should be: S: * 1 FETCH (UID 1 MODSEQ (3) FLAGS (\Flagged \Deleted \Recent)) Here is a proposed patch (WARNING: my C skills = zero): # HG changeset patch # User root(a)bigworm.curecanti.org # Date 1224040830 21600 # Branch HEAD # Node ID 0c0615bc6bf74ccf109049e251a30b8ab5f8ea67 # Parent 40df4d4cced09fa72d37581d0c526416d2c6e3de per RFC 4551, MODSEQ FETCH responses need to be wrapped in (). diff -r 40df4d4cced0 -r 0c0615bc6bf7 src/imap/imap-fetch.c --- a/src/imap/imap-fetch.c Tue Oct 14 14:52:44 2008 +0300 +++ b/src/imap/imap-fetch.c Tue Oct 14 21:20:30 2008 -0600 @@ -749,7 +749,7 @@ modseq = mail_get_modseq(mail); if (ctx->client->highest_fetch_modseq < modseq) ctx->client->highest_fetch_modseq = modseq; - str_printfa(ctx->cur_str, "MODSEQ %llu ", + str_printfa(ctx->cur_str, "MODSEQ (%llu) ", (unsigned long long)modseq); return 1; } Hope this helps/is correct. michael

[Dovecot] Search results as virtual folders
by Daniel L. Miller 15 Oct '08

15 Oct '08

This may have been asked before - if so I apologize. Some mail clients - like Thunderbird - can provide a virtual folder or "saved search" to provide a list of mails that match certain criteria. Obviously, unless special client-side caching is implemented - which Thunderbird (my own client of choice) - does not, generation of these folders take time. Does Dovecot have any provision for generating such virtual folders? Possibly as the result of a sieve script? -- Daniel

[Dovecot] Compatibility namespaces containing a leading ~ appear to be broken in 1.1.x
by David McBride 14 Oct '08

14 Oct '08

Greetings, I'm building a new 1.1.x-series Dovecot installation, and I have a problem setting up compatibility namespaces intended to handle old client-side settings. (See also: http://wiki.dovecot.org/Namespaces#head-0f3ab5ecab632eb517866c3508021e0605d…) I have produced a slightly cut-down example configuration which demonstrates the problem: # dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf protocols: imap imaps pop3 pop3s ssl_cert_file(default): /etc/ssl/certs/imap.pem ssl_cert_file(imap): /etc/ssl/certs/imap.pem ssl_cert_file(pop3): /etc/ssl/certs/pop.pem ssl_key_file(default): /etc/ssl/private/imap.key ssl_key_file(imap): /etc/ssl/private/imap.key ssl_key_file(pop3): /etc/ssl/private/pop.key disable_plaintext_auth(default): yes disable_plaintext_auth(imap): yes disable_plaintext_auth(pop3): no 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_max_processes_count: 1024 max_mail_processes: 32768 verbose_proctitle: yes first_valid_uid: 100 mail_privileged_group: mail mail_location: mbox:~/IMAP:INBOX=~/.email:INDEX=/data/dovecot-indexes/%1u/%u mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): zlib quota imap_quota mail_plugins(imap): zlib quota imap_quota mail_plugins(pop3): 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 imap_client_workarounds(default): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: Mail/ location: mbox:~/Mail:INDEX=/data/dovecot-indexes/%1u/%u hidden: yes subscriptions: yes namespace: type: private separator: / prefix: ~/Mail/ location: mbox:~/Mail:INDEX=/data/dovecot-indexes/%1u/%u hidden: yes subscriptions: yes auth default: mechanisms: gssapi gss-spnego plain passdb: driver: pam userdb: driver: passwd plugin: quota: fs:Disk Quota Given this configuration, a Thunderbird client using a folder prefix of Mail/ is successfully able to enumerate (and access) non-INBOX folders: 5 list "" "Mail/%" * LIST (\Noselect \HasChildren) "/" "Mail/archive"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/Trash"^M 5 OK List completed.^M 6 list "" "Mail/%/%" * LIST (\Noselect \HasChildren) "/" "Mail/archive/"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/archive/INBOX-2008-10"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/archive/INBOX-2008-09"^M [...] 6 OK List completed.^M 7 list "" "INBOX" * LIST (\NoInferiors \UnMarked) "/" "INBOX"^M 7 OK List completed.^M 8 list "" "Mail/archive" * LIST (\Noselect \HasChildren) "/" "Mail/archive"^M 8 OK List completed.^M ...

Through experimentation, it appears that Dovecot 1.1.x doesn't correctly handle namespaces that *begin* with the character '~'; using ~ in the middle of a prefix, e.g. "flibble~/Mail", worked as documented, leading me to suspect a bug in the ~-expansion handling of Dovecot. (Dovecot 1.0.x worked as expected in this configuration.) Unfortunately, an hg bisect run on recent Dovecot-1.1 versions didn't expose the offending commit that introduced this problem, so this bug (assuming it is a bug) was probably inadvertently introduced during the 1.1-development series. Can anyone suggest where in the source tree I should start looking to correct this behaviour? Cheers, David -- David McBride <dwm(a)tastycake.net>

[Dovecot] Get an extra_field in login process

Hi. I have an auth plugin where an extra_field is filled. Somewhere, in login process I need to log the authentication command and the extra_field, I was trying to do it in login-common/client-common.c, adding a new variable to login_log_format_elements and trying to get the fileld from environment, but, I could not find any way to do it, the getenv returns null everytime. Anyone can suggest something to do it ? Is there a way that I get the extra_fields from request in login process ?

[Dovecot] Multiple mailboxes per user
by spam＠wilysloth.com 13 Oct '08

13 Oct '08

My users currently have mail delivered to mulitple MailDir locations via procmail. ~/mail/inbox/ ~/mail/graph/ ~/mail/spam/ I would like all these mailboxes to be exported via dovecot IMAP and appear as folders. However, I can't anything beyond the INBOX working. My approach is via 'namespaces'.

However, selecting 'graph' I see: y:Exit c:Chdir m:Mask ?:Help 1 IMAP ../ ...I would have expected it to open the 'graph' MailDir mailbox and display the mail.
