[Dovecot] Few questions
by Sebastjan Trepca 22 Jul '05

22 Jul '05

Is there a way to list all keywords a mailbox uses? I fetch flags for all messages and then gorup them, but this is a very nasty solution. What's the situation with full text search? Will it ever be implemented? Is it already? Text search on my 0.99.14 is quite slow. Don't understand why no IMAP server wants to implement this feature. Does Dovecot support plugins? Thank you, Sebastjan

[Dovecot] CR LF in stable
by Thomas Hummel 22 Jul '05

22 Jul '05

Hello, It seems that mbox format mailboxes holding \r\n (CR + LF) character sequences (instead of \n only) still cause assertion failures when moving messages from one folder to another. -- dovecot: Jul 19 17:14:52 Error: IMAP(dovetest): file istream-raw-mbox.c: line 38 3 (istream_raw_mbox_get_body_size): assertion failed: (rstream->body_offset != ( uoff_t)-1) -- I seems to work in -test78 though. Is there any plan to handle this in -stable branch ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] deleting folders containing subfolders with thunderbird (mbox format) bug
by John Bramley 22 Jul '05

22 Jul '05

When using Thunderbird (dovecot-0.99.13-3.FC3) on Fedora connecting to dovecot-0.99.13-3.FC3 I am having problems deleting folders which have been created with the 'Allow your new folder to contain: Folders only' option picked. The folder appears to get deleted but upon restarting Thunderbird the folder still appears to be there but clicking on it I get the error: 'The current command did not succeed. The mailserver responded: Mailbox doesn't exist: <mailbox name>'. Upon investigation when creating and deleting a folder called 'bilbo' to contain subfolders only: Thunderbird sends 'create bilbo/' imap command and then 'subscribe bilbo/' Dovecot creates a directory 'bilbo' and adds 'bilbo/' to the .subscriptions file which all works ok. Upon trying to delete the folder and confirming that it should be deleted Thunderbird sends: 'delete bilbo/' dovecot replies 'OK Delete completed' Then thunderbird sends 'unsubscribe bilbo/' dovecot replies 'NO Invalid mailbox name' which Thunderbird ignores and all seems to have gone ok until thunderbird is restarted and the folder reappears in the folder list but nothing can be done with it. I believe that if a client sends an 'unsubscribe' command to a mailbox that is currently subscribed the imap server should unsubscribe it - even if the actual mailbox doesn't exist (unsubscribe and then delete seems to work when testing using telnet to port 143 to send imap commands). Dovecot does allow mailboxes to be unsubscribed if they don't exist if they don't have a tailing '/' character (so deleting folders set to contain only messages in Thunderbird works ok). I expect that everything works ok using Maildir mailboxes because then there is no need to mark folders containing folders with a '/' because all folders can contain messages and folders. For my own purposes I have hacked the mbox_get_mailbox_name_status function in src/lib-storage/index/mbox/mbox-storage.c to add a check to see if the mailbox name is already subscribed to and if it is then return status = MAILBOX_NAME_EXISTS, before the 'if (!mbox_is_valid_create_name(storage, name))' check which is returning status = MAILBOX_NAME_INVALID, which seems to work ok for me. UW-imap works ok I'm surprised at this bug (or am I doing something completely wrong), surely lots of people use Thunderbird with dovecot, do they not create sub-folders in folders, or are they all using Maildir format, or do they never find the 'Server supports folders that contain sub-folders and messages' advanced option so they are never able to create folders within folders in the first place?

[Dovecot] Failed to create storage with data - possible reasons?
by vmstech 22 Jul '05

22 Jul '05

Hi I'm getting this error with my attempt at setting up dovecot for virtual mail accounts: Failed to create storage with data: /home/vhostpath/usersname/Maildir/ I cant establish any cause. I dont think its permissions as it was saying 'Permission denied' till I fixed that and the UID and GID are those of the directories owner. I was prompted bythe log files to set the minimum and maximum uid range, which made the prompt go away, but I still have this problem. Can anyone tell me what else might cause this error? Thanks glenn

[Dovecot] Update notifier
by Sebastjan Trepca 22 Jul '05

22 Jul '05

Hi, I'm trying to add a code in dovecot that will notify my services when a message is updated/added/moved/copied. I checked dovecot code a bit and mail-storage.c seems to be a nice place for tracking but I'm not sure if I can track all changes there. Does anyone have any experience with this topic or ideas?

[Dovecot] Dovecot vs.Clients - strange behaviour, diagnostics sought
by Jeroen Scheerder 22 Jul '05

22 Jul '05

I've been experimenting with dovecot-1.0-stable on Solaris. Storage format is mbox. Dovecot, in test, runs in parallel with an UW IMAP, with dovecot running SSL-only on port 994. It seems to work to some extent: * dovecot runs * authentication works * SSL works * all manual IMAP functionality checks seem to work fine However, I'm running into issues with IMAP clients. * Null client: I started by using telnet as a client, and talking IMAP manually. Seems OK. * Mutt: "mutt -f imap://my.imap.server:994" seems to work well, although mutt keeps reporting details about the SSL certificate, informs me that it belongs to the proper server and is a valid Globalsign-issued certificate -- and keeps insisting I either reject it or accept it once. * Apple Mail (Panther's version, 1.3.11 (v622)) works, though it seems to have problems with large mailboxes. Then again, it had these same problems with other IMAP servers as well. * Thunderbird doesn't work at all. After some waiting, it bums out and reports: Unable to connect to your IMAP server. You may have exceeded the maximum number of conenctions to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections. Note that it never even shows an authentication dialog, and the only thing I see in dovecot's log that relates to Thunderbirds attempt is: dovecot: Jul 20 09:41:09 Info: imap-login: Disconnected: \ Inactivity [131.211.143.87] I'm at a loss as to what's causing this. On the one hand, dovecot seems operational, on the other hand at least one client can do nothing with it. All debugging/logging options are enabled. What am I missing?

Fwd: [Dovecot] Very slow select() command on large mailboxes
by Sebastjan Trepca 22 Jul '05

Maildir, its easier to export and can support hardlinks. What kind of optimizations did you have in mind? What's the downside of mbox? Problem is that version 1.0 is only test release for now.

[Dovecot] configuration of user_global_uid and user_global_gid

[Dovecot] Changing port?
by Matt Juszczak 22 Jul '05

22 Jul '05

Hi all, Trying to setup a test copy of dovecot on my box before I "really" use it. I have it installed into a test dir (/usr/local/dovecot instead of /usr/local), and I've got a config file with valid dirs, etc. Only thing is ... I can't find a way to set the port in the protocol pop3 {} section. Its documented in the "listen" directive area at the top of the config file that says its possible, but no other mention of it is ever made. How can I make my test copy listen on port 111? :) Regards, Matt

[Dovecot] Can't connect to auth server
by Todd Burroughs 22 Jul '05

22 Jul '05

I've been seeing these errors intermittently for a while now. Here's an example from the logs: dovecot: Jul 12 15:59:05 Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable The error is EAGAIN. Sometimes it will resolve itself after a few minutes and sometimes it needs to be restarted (it may fix itself, I usually get a phone call if it goes on for very long). I've looked while the problem is occuring and dovecot and dovecot-auth don't have an excessive number of file descriptors open, maybe 10 or 20. Any ideas or anything else to look at? The system is SuSE Linux 9.2 running kernel 2.6.x. We have seen some odd things happen with these systems, so it is possible that it is not dovecot. The kernel doesn't log anything unusual and other processes seem happy. Todd

[Dovecot] test76-77 dies at SIGHUP
by Johan Fredin 22 Jul '05

22 Jul '05

Hello people This is on OpenBSD/sparc64. After chickening along with 0.99 for a while, I finally upgraded to 1.0-test. I started out with test73, which worked fine. With the upgrade to test76, I lost the ability to SIGHUP dovecot when I rotated it's logfile. Dovecot would just die abruptly, not a trace in the log. I just upgraded to test77, but the problem is still there. I've put up my logfile and the last bit of a ktrace here: http://legonet.org/~griffin/tmp/dovecot/ The ktrace is partitial mostly because it contains usernames, I can edit those out and upload the hole shebang if that'll help. I'd appreciate any tips/pointers on this one! /Johan

[Dovecot] test77, yahoo & fetchmail
by Chris Spiegel 22 Jul '05

22 Jul '05

I've run into a rather narrowly scoped problem .. On test77 and test78, mails from Yahoo's webmail are seen, by fetchmail using imaps, to have a 0-length body. When fetching, it claims "0 body octets". Other mail clients (mutt, kmail) can view the messages fine. pop3s retrieval works as well. Every other email I've received so far works fine. It's just those sent by Yahoo's webmail service that have the problem. imaps retrieval does, however, work fine with test76. Let me know if there's anything I can do to help track this down. Thanks, Chris

[Dovecot] linux 2.4 vs 2.6 kernel

hi I read ( I think in dovecot wiki) that ext2 or ext3 fs on a 2.4 kernel can get slow due to the number of files in a directory. Does anyone know if kernel 2.6 has similar limitation? I'm not at that point now, but before the box goes live, I'm wondering if I should resolve that. Glenn

[Dovecot] Debian has moved to 1.0stable

Now that sarge has been released, I have as requested moved Debians' Dovecot packages to the 1.0stable branch. Most of the work was actually done by Fabio Tranchitella who is joining me as co-maintainer. The new packages should be available in sid later today. A backport to sarge will also be provided as soon as I can get around to it. Please report all problems to the Debian bug tracking system (see http://bugs.debian.org for instructions or use the reportbug package) not to me directly so that Fabio can also see. -- Jaldhar H.

> > >> ------------------------------------------------------------------------ > We were posed with the same dilemma, but it was due to the need to stick with RHEL supplied packages (ReiserFS does not come with RHEL) that we stayed with ext3. Our old production mail server, running our in-house flavour of Linux, was based on the 2.4 kernel with ReiserFS. We load tested Dovecot with maildir under RHEL3 (2.4 kernel) using ext3 and found it was unable to standup to our requirements. In part this was due to an inordinate imap-login / pop-login processes being created and hanging around under RHEL3. Using RHEL4 (2.6 kernel), we found we were able to handle the required load - this is the configuration we went live with. Processes ended cleanly too (result of the improved schedular and how it interacted with our IBM x445 and its NUMA architecture?) and the I/O issues seemed to have been resolved - ext3 was fine. >> Subject: >> Re: [Dovecot] linux 2.4 vs 2.6 kernel >> From: >> Marc Perkel <marc(a)perkel.com> >> Date: >> Mon, 18 Jul 2005 18:33:54 -0700 >> >> CC: >> dovecot(a)dovecot.org >> >> >> >> >> Curtis Maloney wrote: >> >>> Marc Perkel wrote: >>> >>>> Actually - yes.

Re: [Dovecot] linux 2.4 vs 2.6 kernel
by Brian Bartholomew 19 Jul '05

19 Jul '05

I can heartily recommend reiserfs on kernel 2.4 for Intel and Sparc. My spam filtering setup currently has 27K files in a quarantine dir, and it works just fine. In a year and a half over 50 machines I've had three corrupted reiserfs filesystems, none of them on production machines, at least one of which I can blame on a bad disk. I would not be surprised to learn they were all bad disks, because the disks are five+ years old. For the last one I moved the bad dir aside where it sat peacefully for a week, and when I fsck'ed it the more aggressive mode of fsck coredumped partway through and it became unaccessable. I then restored it from the tar I had made prior. Brian

[Dovecot] IMAP: Get rid of non-existent folders below INBOX
by André Wendt 19 Jul '05

19 Jul '05

Hi, I am using Debian Sarge w/ dovecot-imapd package 0.99.14-1. Squirrelmail created three folders below INBOX, Drafts/Sent/Trash, that I already had elsewhere. Thus, I deleted them (through SqM). However, both Thunderbird and Squirrelmail still show these folders anyway. When I select them, I keep getting "Mailbox does not exist" errors. I already tried to move all .imap.index* files in .INBOX/ out of the way -- dovecot created new ones but the folders still appear. I am stuck. How can I prevent dovecot from advertising those non-existent folders? Is this an index-structure problem? I'd appreciate any suggestions. Thanks, -- André

[Dovecot] issues/workarounds to build dovecot on OSX

[Dovecot] "dovecot virgin": 1st questions ...
by OpenMacNews 17 Jul '05

17 Jul '05

hi all, "uncle"! i've thrown up my hands with cyrus, and am looking for a 'better alternative' ... i'm brand new to dovecot (haven't even built it yet ...), and have spent the last while reading through the LIST archives here. apart from the TECHNICAL aspects, which seem _more_ than adequate/competitive, i'm most attracted by a comment abt this LIST/community: > awesome technical support with patient developer-dudes on hand which, in a nutshell, is what i seem to be missing. so, i'm preparing to "take the plunge" w/ dovecot. two preliminary questions, if i might: (1) what sort of *interest* is there here (Timo? others?) in Dovecot on OSX? i'm usually able to get most anything up-n-runnig on my OSX boxes, but i'd like to join a community where every issue-on-Mac is not simply ignored/slammed ... and there might be folks willing to work with me on issues (2) here-we-go-again with the Maildir/Mbox decision :-) what's the latest thinking/recommendation here wrt mailbox/mdir? my specifics are -- i intend to backend Dovecot with Exim ... and will run my server 'closed box' ... i.e., no file-system-related User accounts. rather, just 'virtual' spaces. i'm leaning towards Maildir's one-flat-file-per-message format, with an eventual/possible move to storage in PostgreSQL if/when Dovecot adds the capability ... thoughts? (yes, i know, y'all must've had the discussion a g'zillion times ... a pointer to a good/relevant thread is great too!) cheers, richard

[Dovecot] Authentication feature I need
by Marc Perkel 17 Jul '05

17 Jul '05

OK - here's whay I need to make it work for my Linuxconf compatible authentication system. First - a question: Will this work? I can find docs on "virtualfile. auth virtualfile { mechanisms = plain digest-md5 userdb = passwd-file /etc/vmail/passwd.%d passdb = passwd-file /etc/vmail/shadow.%d user = root } Then - since the dmain name selects the passwd file, if there were a feature to make %n be us user instead of the whole email address then I have what I need. Password files are placed in the /etc/vmail directory as follows: /etc/vmail/passwd.domain1 /etc/vmail/shadow.domain1 /etc/vmail/passwd.domain2 /etc/vmail/shadow.domain2 The password and shadow files are exactly the same format as the /etc/password and /etc/shadow files. The user name within the files would be the %n part of the email address passed to authenticate with. Basically the password file names are /etc/vmail/passwd.%d with the user withing the file being %n. marc:x:40000:12:Marc Perkel:/vhome/perkel.com/home/marc:/bin/false test:x:40001:12::/vhome/perkel.com/home/test:/bin/false dd:x:40002:12:Atia:/vhome/perkel.com/home/dd:/bin/false test2:x:40003:12::/vhome/perkel.com/home/test2:/bin/false

[Dovecot] Feature Request - Authentication Scheme - Linuxconf
by Marc Perkel 17 Jul '05

17 Jul '05

This would make my life a lot easier in migrating to Dovecot. And it should be really easy to implement. Here's how linuxconf does it: Password files are placed in the /etc/vmail directory as follows: /etc/vmail/passwd.domain1 /etc/vmail/shadow.domain1 /etc/vmail/passwd.domain2 /etc/vmail/shadow.domain2 The password and shadow files are exactly the same format as the /etc/password and /etc/shadow files. The user name within the files would be the %n part of the email address passed to authenticate with. Basically the password file names are /etc/vmail/passwd.%d with the user withing the file being %n. marc:x:40000:12:Marc Perkel:/vhome/perkel.com/home/marc:/bin/false test:x:40001:12::/vhome/perkel.com/home/test:/bin/false dd:x:40002:12:Atia:/vhome/perkel.com/home/dd:/bin/false test2:x:40003:12::/vhome/perkel.com/home/test2:/bin/false It also makes merging several servers with separate passwd/shadow files into one virtual system because all you have to do is copy their existing passwd/shadow files into the /etc/vmail directory and rename them with the domain at the end. So - wouldn't that be easy to add? Sure would make migrating easy for me. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] user_db, uid/gid and maildir
by vmstech 17 Jul '05

17 Jul '05

Im experimenting with putting all my virtual users mail under 1 directory with belonging to a system user created for the purpose. The mode on the directory (and subdirectories) is 770. I keep all my virtual users details in a postgres database. My interpretation of the wiki documentation is that if the user_db query returns a uid column and a gid column containing the numeric uid and gid of the owner of the directory, then dovecot should have no problem using mail in these folders. Is that correct? (I'm actually getting permission errors appear in the log file on the directories when I try and attach with a client, which reports "Cannot get LIST information for pattern `*' on IMAP server a.b.com unknown".) thanks Glenn

[Dovecot] Authenticaing in postgresql
by vmstech 17 Jul '05

17 Jul '05

Hi all - Im new to dovecot and actually all things email serverish. I spent last week wrestling with exim4, and this week its dovecots turn. I'm trying to connect as an imap user (from evolution) and not actually able to make a successful login. I have default_pass_scheme=PLAIN, and am using pass authentication in evolution client. Its the only one available after it queries the server for available types. I'm not getting any errors appear in either the postgres or dovecot log files (anymore :-) that is). I'm getting the exact query I'd like to see in the dovecot log file, after I entering the password in the client, but unfortunately it doesnt give me the reply. I can key this exact query in to the psql client and get the correct answer. dovecots logs don't tell me if I have success or failure. The auth_db query has only 1 column. I have no idea where to go from here - would love a hint thanks Glenn

[Dovecot] OS X Mail.app 2 (Tiger) + dovecot -> new mail count doubled
by Alan Schmitt 14 Jul '05

14 Jul '05

Hello, I've noticed a strange bug with Mail.app 2 (from OS X.4) and dovecot, and I'm trying to identify where it comes from. I have a bunch of mailboxes that can receive new mail (delivered by procmail) and I have Mail set up as to automatically synchronize all maiboxes. When I start up Mail, the count for new mail is doubled in every mailbox that I have not seen yet. Looking at a mailbox restores the correct count (mail is not actually duplicated, it's just the new mail counter that is wrong). Has anyone else seen this? Would this bug be from Mail.app or from dovecot? (I suspect the former.) Thanks a lot, Alan Schmitt

[Dovecot] Very slow select() command on large mailboxes
by Sebastjan Trepca 14 Jul '05

14 Jul '05

Hi, I'm trying to decide if I could use you mail server in our enviroment which has about 10k users and mailboxes size about ~1GB. So I made a few tests and it all worked quite fast, except that select command on large mailboxes. The first time I select a mailbox which has 10k messages it takes about 4s to process. I am deliberately trying this on a Celeron 850Mhz, 512 MB memory and some shitty hard-drive to maximize the times. So why is this so slow? Does it index the messages on select? It's even slower when I have some new messages in folder, more that I have more I wait. So I presume it must be something with indexing? Anyway, how could I optimize this? Why don't you index when a mail arrives instead of on select? Thanks for help and keep doing a great job with Dovecot. Sebastjan

Yes, of course. Certificates are made out to a particular hostname (e.g. smtp.wahtever.com) and if you change your server hostname or move it to another server, a new certificate will have to be made out to the new hostname. You could also configure your client ignore certificate mismatches, but this wouldn't be the best option. Joseph Tam <tam(a)math.ubc.ca>

[Dovecot] Search with specified charset
by Chris Wakelin 14 Jul '05

14 Jul '05

I've seen a problem with searching in the Prayer webmail client that turns out to be caused by Prayer insisting on a charset called "ISO-8859-1" and Dovecot, using Solaris iconv, not recognising it (all the Solaris 8 iconv modules appear to be "ISO8859-1" etc. or just "8859-1"). This isn't a problem in Linux: % iconv --list | grep 8859.1/ 8859_1// ISO-8859-1// ISO8859-1// ISO885911// ISO_8859-1// I've hacked together a patch for Dovecot to try matching without the "ISO-" prefix if matching fails at first, which works for Solaris (as would creating an extra symbolic link in /usr/lib/iconv or hacking Prayer to use "ISO8859-1") and it doesn't break Linux, but it's not pretty :( Better may be to try substituting underscores, hyphens, spaces(?) and nothing in the string, but that makes the change much more complicated!

Hi! I have an mail server with postfix and dovecot. All works fine, but now is change my domain. After changed configurations i can receive (or send) mail without STARTTLS, but when i try to use this option i receive: "TLS handshake failure. Invalid server certificate (Key material mismatch)" I dont know what is this. I use certificate that is generate with script for dovecot (that work at begining). Even i try to rebuild this certificate acording with new domain but nothing. Where is my problem? P.S. All works before changed my domain!!!

[Dovecot] Minor bugs still in test77
by Chris Wakelin 13 Jul '05

13 Jul '05

Thinking of patches I always apply, I've got a couple (attached) that fix minor bugs and maybe should be applied - or implemented better and then applied ;) - to the main distribution? 1) LIST bugs: LIST "~/mail/" "" and LIST "" "~/mail/" (where "~/mail/" is a namespace prefix) don't reply the same way as UW-IMAP does and in at least the first case, still violates the spec (your fix breaks, as namespace_find() modifies its argument) The second issue breaks Pine 4.x, I think. 2) Angle-addresses If a header address is just "<someone(a)somewhere.org>" rather than "Someone <someone(a)somewhere.org>" or "someone(a)somewhere.org", then the FETCH ... ENVELOPE command responds with "" as the personal name, rather than NIL, which may confuse clients (without being wrong, technically, I think). (In case anyone's interested, I also use patches to: 1) fix the 64bit issue mentioned earlier today 2) introduce extra logging of LIST, SUBSCRIBE and UNSUBSCRIBE (for debugging during our migration from UW-IMAP) 3) rename .subscriptions to .mailboxlist and store folder names in it including the namespace prefix (to emulate UW-IMAP) 4) implement a Reading-specific hashing algorithm for the mail spool location as an extra variable modifier "%H" (e.g. "/export/mail/%Hu/%u/INBOX") 5) remove the need for /dev/urandom, which isn't available on our mail server (though there is a Solaris patch available to create it). 6) add an option to hide "AUTH=PLAIN" in the CAPABILITY string as Pine 4.x complains loudly when this is advertised on a non-SSL connection ) Best Wishes, Chris -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094 --- dovecot-1.0-test77.orig/src/imap/cmd-list.c Sun Apr 17 17:37:05 2005 +++ dovecot-1.0-test77/src/imap/cmd-list.c Wed Jul 13 16:10:27 2005 @@ -372,7 +372,8 @@ concept which probably no other client uses than Pine.

[Dovecot] New to dovecot, little luck - signal 10 death for imap
by Jeroen Scheerder 13 Jul '05

Hi, I'm a new prospective dovecot user. I'm planning to migrate a medium-scale mail site (a few thousand users) from UW to something better. I've set up dovecot on a test system. I can connect and authenticate just fine. IMAP clients get to see the right mailboxes. However, whenever a mailbox is selected, the imap subprocess dies. The log shows: Jul 13 14:52:05 localhost dovecot: imap-login: Login: js [127.0.0.1] Jul 13 14:52:07 localhost dovecot: child 8082 (imap) killed with signal 10 When I either telnet to it manually or run the "imap" process in a terminal window, everything seems to work: ---- Snip ---- * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as js x select INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 1300 EXISTS * 0 RECENT * OK [UNSEEN 2] First unseen. * OK [UIDVALIDITY 1119092680] UIDs valid * OK [UIDNEXT 1590] Predicted next UID x OK [READ-WRITE] Select completed. x fetch 1 full * 1 FETCH (FLAGS (\Seen) INTERNALDATE "18-Jun-2005 05:00:02 +0200" RFC822.SIZE 1773 ENVELOPE ("Sat, 18 Jun 2005 05:00:01 +0200 (MET DST)" "Waarschuwing: uw inbox overschrijdt 80% van de groottelimiet (18-06-2005)" (("Super-User" NIL "helpdesk" "phil.uu.nl")) (("Super-User" NIL "helpdesk" "phil.uu.nl")) (("Super-User" NIL "helpdesk" "phil.uu.nl")) ((NIL NIL "js" "phil.uu.nl")) NIL NIL NIL "<20050618030001.B5F3952048(a)goedel.admin.phil.uu.nl>") BODY ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 1082 25)) x OK Fetch completed. x fetch 1 body[text] * 1 FETCH (BODY[TEXT] {1082} Beste Jeroen Scheerder, [...] Met vriendelijke groet, het systeembeheer. ) x OK Fetch completed. x list * * * LIST (\Noselect \HasChildren) "/" "Archive/" [...] * LIST (\Unmarked) "/" "INBOX" x OK List completed. ---- Snip ---- I'm at a loss here, and no amount of logging or sniffing with tcpdump has revealed anything interesting so far.

[Dovecot] Headers "missing" in new CVS version
by Todd Burroughs 13 Jul '05

13 Jul '05

We're experiencing an odd problem with dovecot "losing" headers. This started happening with the CVS release as of July 4 and still happens with July 12. It was working properly June 28. It does not happen using pine or thunderbird. It happens using webmail (twig). When you open the inbox, you see subject, etc. When you open a mail, all of the headers are gone. Returning to the inbox, all the headers are missing. It seems to cache this as well. After returning to the older dovecot, all of the headers are missing. Deleting the cache files fixes this and there does not seem to be any mbox corruption. It does not log any errors or crash. Todd Burroughs

[Dovecot] add inotify support to dovecot
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, attached patch against test76 adds inotify support and the --with-notify=... configure option that defaults to the current check for dnotify using no special method if dnotify cannot be compiled, and can be set to none, dnotify and inotify. If it is set to dnotify or inotify, failure to compile a test program results in an error. Also, it adds | file change notification method ..... : <method> to the output at the end of configure. The only thing I don't like about this patch is the fact that I had to add a field notify_context to struct io, but I didn't see a different way to handle this. Also, the patch doesn't support the condition parameter, it simply always asks for all the relevant changes. I don't really see that it is useful for in the context of file system notifications anyway. I modeled this after ioloop-notify-dn.c with my other patch applied to it, if you don't like the other patch you'll want to "revert" that change in the new ioloop-notify-inotify.c file as well. Oh, and obviously I didn't include patches to configure and all the Makefiles, so of course you'll have to run automake. But you already knew that :) I only tested this with maildir. I did add IN_MODIFY so I think it should work with mbox too, but someone should probably verify. Have fun, johannes

[Dovecot] sorting question
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, If I understand the thread sorting algorithm correctly (from draft-ietf-imapext-sort-17.txt and the code), it will sort like this (where I use numbers instead of dates with higher numbers being newer mails) 4 10 3 11 2 12 1 13 etc into all the lower levels. Thunderbird will actually sort this like this: 1 13 2 12 3 11 4 10 where threads are sorted by the newest child in them. Now, I am thinking that evolution simply uses dovecot's THREAD feature and doesn't implement anything itself, so that if I wanted to have that kind of threading, I'd have to implement it in dovecot. Would this be easy? I'm thinking that I should just treat all nodes as if they were dummy nodes in sort_root_nodes, but that only fixes the first level afaict, because later dates are not propagated up. Essentially, I think what the algorithm tb uses does is not use a nodes date as it's sorting criterion, but it's newest child, and apply this rule recursively. Does anyone else think this feature would be useful? I regularly end up almost missing mail because it is sorted at such a low position and I don't see the thread at all.. johannes

[Dovecot] 1.0-test77
by Timo Sirainen 13 Jul '05

13 Jul '05

http://dovecot.org/ It's hot in here. Something like 25-30c for many days now. My brains don't work in that heat. So, this is still not an 1.0-alpha1. I'll put it out when I think the release will actually be fully working :) Changes since test76: - Fixes to FETCHing MIME body parts, especially with message/rfc822 attachments. We hadn't been handling this entirely correctly ever (this part of IMAP spec was pretty difficult for me to understand earlier..). This also caused Dovecot to sometimes disconnect clients fetching [n.MIME] body parts earlier, if someone had that problem. - Maildir: Several bugs fixed with APPEND/COPYing mails - mbox: Keywords weren't stored to index with APPEND - inotify patch by Johannes Berg (and possibly broken by me). Can be enabled with --with-notify=inotify parameter to configure. - SEARCH now doesn't fail if a messageset outside valid range is given to it. Some mobile IMAP client was broken because this didn't work. - Cache mail headers when saving mails to mbox. We should cache everything, but this is a start.. - And other cache file fixes/optimizations

[Dovecot] Dovecot 1.0-stable mbox performance and disconnections
by Chris Wakelin 12 Jul '05

12 Jul '05

I've got some of our busiest users now using Dovecot instead of UW-IMAP with mbox-format mailboxes and predominantly Outlook Express as the client. Doing some perfomance monitoring (with Solaris 8 process accounting), it looks like Dovecot needing to read only 30-50% of the disk blocks needed by UW-IMAP, but I was hoping for better! What seems to happen, is that most of the connections use only a small number of blocks (due to Dovecot indexes, presumably) but occassionally a process will read lots of blocks, sometimes even more than a UW-IMAP session. Is this expected, or is something going wrong with the index updates? I have the default sync settings, I think (mbox_dirty_syncs = yes, mbox_very_dirty_syncs = no, mbox_lazy_writes = yes) My INBOX is an extreme example with ~10,000 messages and most processes reading a few hundred blocks but a couple using 20,000 or so! Also, Dovecot seems to be dropping connections, sometimes, for no good reason (putting some extra i_info lines suggests for "inactivity"). Thunderbird tends to reconnect automatically, though. It seems it may be happening at the end of an IDLE command, something like:- 4 IDLE + idling * 1005 EXISTS DONE * 1005 EXPUNGE but then the expected 4 OK Idle completed never comes. Has anybody else seen this?

[Dovecot] newbie questions
by Stewart Dean 12 Jul '05

12 Jul '05

Thanks in advance for your patience and assistance. Since a system administrator's work is most successful when nobody knows you've done anything....(ugly that...you get neither raises nor equipment funding as a result), I prefer to learn from other's experiences rather than fail in the same pits. We are considering a switch from UW to Dovecot, since our users persist in using the INBOX as a file cabinet (maybe 25% use homedir folders) and we currently have, I think, .mbox INBOXes which are thus getting massively unmanageable and fragile. Machine config: Running IBM AIX 5.2/5.3 on an F80 with 4GB memory (may be upgraded to 16GB), with IBM's sendmail binary at V8.11.6p2, hand compiled procmail at 3.22, 64-bit binary from C for AIX V6.0 Some questions I couldn't find answered in the docs: 1) Crispin of UW has a formats.txt file in which he lists and evaluates the various formats. He calls the INBOX format type we use .unix (one big honking flat file). Q1: Is this what is described in the Dovecot docs mail-storages.txt file as .mbox? 2) Authentication: The DC docs don't mention using NIS/yp for authentication, that I can find. Q2: Does DC support NIS/yp authentication? I guess I could periodically do a ypcat passwd to a file and point DC at it... 3) on IBM's AIX Unix... Q3: Is there anyone out there running DC on AIX? 5.x or 4.3.3? JFS or JFS2? 4) Inbox location/format: = I will want to move from our legacy .mbox format to, I suppose, the DC default of Maildir++. = I will want to do this in groups over time, rather than all at once, so both formats will have to work = The legacy location of INBOXes has been /var/spool/mail/<userid>. The docs appear to say that Maildir format INBOXes should be in ~/Maildir. Q4:Can the INBOXes be in two location, the converted new Maildirs in ~, and the old unconverted in vsm? Or will I have to override the DC cfg'ed INBOX location to be VSM until I get them all converted and then move them all to ~/Maildir and change the DC config to that? 5) Some mention was made of procmail configuration issues Q5: Can procmail support both formats/locations, or will I have to put changes in the migrated users' procmailrc (what fun!)?

Hello, Does dovecot require mysql in order to work? Fedora rpms are claiming mysql dependencies. I'm sure you're aware of the long-lived arguement of postgresql v. mysql.

[Dovecot] bug: very strange behavior with pop3
by Yannick Majoros 12 Jul '05

12 Jul '05

Hello, We have some strange problem which could be related to authentication here. All our user info is in an openldap directory. We normally use pam/getpwent in dovecot to access our user accounts, via nss_ldap/pam_ldap, but we tried to connect directly to the ldap server, with the very same results. We have one user (out of 100) which just cannot use dovecot with pop3. His login/password are accepted, and then dovecot doesn't say anything. I am sure it isn't a client issue: same result with Eudora, Thunderbird and while directly connecting through openssl to POP3s port and "talking POP3". Here is some session transcript: +OK dovecot ready. USER rinstalle +OK PASS M=/)p365 +OK Logged in. And it then stops responding (without giving a reason, breaking the connection). Nothing in the logs, it sees this as a regular login and that's all... Now, it seems that when I copy this user in ldap, the new one occasionaly works. I first thought it did depend on the user name (uid or dn), but it doesn't seem to be the case. I think it is just random. Here is an ldif of this user: dn: uid=rinstalle,ou=divers,ou=login,ou=Autres,ou=Personnes,dc=inma,dc=ucl,dc= ac,dc=be uid: rinstalle cn: compte foireux homeDirectory: /home/xx sn: xxxx uidNumber: 9999 objectClass: top objectClass: person objectClass: inetOrgPerson objectClass: posixAccount gidNumber: 999 ... And getent result (with nss_ldap): #getent passwd rinstalle rinstalle:x:9999:999:compte foireux:/home/xx: To be complete, I should mention that it _does_ work when using local password files... I solved the user problem just by copying his entry a few times. Now, I don't think it is purely ldap-related, as the login _is_ accepted. Is there some guru out here who could help us?

Hi, So I was testing things with inotify notifications enabled and noticed that when I a) select a mailbox other than the inbox b) IDLE c) copy mail into the /new folder in that mailbox nothing happens! So I straced it and it always opens the inbox's new/ and cur/ directories for notifications. Is that the correct behaviour? I assumed that if I select some mailbox other than the inbox, IDLE should inform me of status updates in that box, since RFC 2177 says: The Internet Message Access Protocol [IMAP4] requires a client to poll the server for changes to the selected mailbox (new mail, deletions). Now, I get this behaviour by applying the attached patch. But even if I'm wrong, dovecot doesn't implement any sensible behaviour, as it only ever creates *any* notifications during IDLE when the INBOX is selected. [hm. note that I'm only testing maildir] johannes

[Dovecot] POP retrieval, then reading, of mail does not udpate server status.
by Paul Vatta 12 Jul '05

12 Jul '05

We are currently using the version of Dovecot (0.99.11) that comes with Redhat Enterpise Linux version 4, running on an IBM x445 server (8 CPU, hyperthreading on, 14GB RAM) using the maildir format. We have had to patch this with a change from 0.99.12 so that it doesn't incorrectly report SASL capability upon connection but otherwise it is the version supplied with the OS (we do this to ensure that we don't deviate from the supplied packages too much). The problem encountered is the status of emails on the server isn't being updated. The POP client (Eudora 6.2 in this instance) will retrieve the message, have the message read, apparently update the status on the server (via the "Check Mail" function), but yet the status on the server has not been updated as read (verified by going into our IMP Webmail client, and looking at the mail message in the mailstore - there is no ".S" extension). Using the IMAP protocol doesn't bring about this behaviour. The inconsistency The inconsistency between POP clients and the server status doesn't occur when it comes to deleting messages. Is this a bug, or have we misunderstood how the POP protocol works. Looking at the following: http://www.eudora.com/techsupport/kb/2587hq.html I'm guessing that the POP protocol doesn't update the status? Your confirmation would be most appreciated. Thanks, Paul P.S. As an aside, if you are hesitant about the move from mbox to maildir, don't consider this an obstacle. Our migration was painless and the benefits far outweigh the conversion effort. Dovecot has introduced huge improvements over our Qpopper/UW-IMAP configuration.

Hi all, We're running dovecot without a chroot (mail admin's request), but we're running it as a non-priv'd user with proper firewall setup. Does this seem to be an OK and average setup? Or is it considered a MUST to chroot something like the imapd daemon, etc. Thanks! -Matt

[Dovecot] Creating encrypted passwords for new users /etc/imap.passwd
by John_R._McWade 09 Jul '05

09 Jul '05

Hello. I've been attempting to locate information on how to actually create the encrypted passwords for a new user in /etc/imap.passwd file. Im really going into this blindly, not having ever used dovecot before, and really just need to be pointed to any existing resources on this topic. This is a setup of dovecot (w/ sendmail,squirrelmail) on FC2. I've got one successful auth so far as a test user, with their info cut/pasted directly from /etc/passwd (it works) whereas using {PLAIN}password causes dovecot to drop the connection with an aborted login. So what I'm actually looking for is a resource or a quick response regarding the actual creation of the encrypted password in /etc/passwd style. Any clues on where I should look for this info? John

[Dovecot] stat() failed with mbox /var/mail/%u
by Jungshik Shin 08 Jul '05

08 Jul '05

Hello, Over the last 12 hours or so, I've been wrestling with a mysterious dovecot issue. After upgrading a mail server I'm helping my friend with maintaining from Fedora Core1 to Fedora Core4, I realized that I couldn't use UW-IMAP4 anymore (well, I can compile it myself, but it turned out that UW-IMAP was the main cause of the server's having load average as high as 30 from time to time so that I decided to move onto dovecot). Although I loved to migrate to maildir, I didn't dare to tackle the migration (I have a lot more important things to do :-)) to maildir. Instead, I thought that dovecot's indexing of mbox files should make the performance of the server a lot better than UW-IMAP. (in addition, we upgraded the HW from P3 800MHz single to P4 dual 3GHz). Last night, I experimented with several mboxes of one user's account (INBOX in /var/mail/<userid> and others in ~/mail/) and it worked perfectly well. So, I moved mboxes of other users and launched 'dovecot' informing users that the mail server is back up again. However, it didn't work with inbox (for IMAP) and POP3. There's no problem accessing mail folders in '~/mail', but accessing /var/mail/%u (inbox for IMAP) and using the same folder with POP3 didn't work. The error I got in the log file is: Jul 8 01:17:24 biosoft dovecot: pop3-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 01:17:24 biosoft dovecot: POP3(xyz123): stat() failed with mbox file /var/mail/xyz123: Permission denied Jul 8 00:34:45 biosoft dovecot: imap-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 00:34:45 biosoft dovecot: auth(default): Error sending status request (Operation not permitted) Jul 8 00:34:45 biosoft dovecot: imap-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 00:34:45 biosoft dovecot: IMAP(xyz123): stat() failed with mbox file /var/mail/xyz123: Permission denied ls -ld / /var /var/mail/ /var/mail/xyz123 drwxr-xr-x 23 root root 4096 Jul 7 19:28 / drwxr-xr-x 26 root root 4096 Jul 7 23:35 /var drwxrwxrwt 2 root mail 4096 Jul 8 00:36 /var/mail/ -rw-rw---- 1 xyz123 mail 130751237 Jul 7 23:37 /var/mail/xyz123 I tried various combinations of permissions and ownerships for /var/mail (1777, 2775) and /var/mail/<userid>, but nothing made any difference. I also tweaked mbox locking methods ('dotlock fcntl' or 'fcntl' alone) When I came across this problem with the latest stable (2005-07-06), I went back to FC4's default package (0.99??), but with a slightly different error message in the log file, basically I had the same problem. I kept the default values for most configuration parameters. What I changed are listed below: mail_extra_groups = mail pop3_uidl_format = %08Xv%08Xu protocols = imap imaps pop3s default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u Also attached is the entire /etc/dovecot.conf I'm really desperate to get some enlightening answers on this problem, for which I'll really appreciate you.

Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. #separator = / # Prefix required to access this namespace.

[Dovecot] IMAP Folders
by Matt Juszczak 07 Jul '05

07 Jul '05

Hi all, We're using the mbox format and I tried setting up IMAP on my boss's computer tonight. He likes subfolders, and although they work, he can't seem to remove subfolders once he created them, nor create new folders without using something other than his mail client (like mkdir from the command line). Any ideas on this? Does dovecot just not officially support IMAP and subfolders with the mbox format? Or could it be a permissions issue? -Matt

[Dovecot] Username mapping
by nodata 06 Jul '05

06 Jul '05

Hello. We're using dovecot with mysql for authentication, with postfixadmin for the admin web interface. We are moving users from passwd file usernames to email@domain style logins. Is there a better way to allow both sets of usernames (old and new) to work with dovecot than by adding extra copies of rows to the mailboxes table and changing the username? i.e. does dovecot support some kind of username mapping or aliasing? Thanks a lot

[Dovecot] dovecot 1 for production? which one?
by Jeff A. Earickson 06 Jul '05

06 Jul '05

Hi, I've been lurking on the list since Spring, planning to replace UW-IMAP with dovecot 1.0 sometime this summer. The recent thread on "1.0" has not given me a good feeling about seeing it before summer's end. So I wonder if I should use dovecot-1.0-test-xx code or dovecot-stable-[date] code (which seems to change every day, how stable is that???). This is confusing, advice please.

[Dovecot] Root password or key access to pop3?
by Matt Juszczak 05 Jul '05

05 Jul '05

Hi all, We're an ISP, and are currently looking for a way for our tech support guys to access customer's email without having shell access to the server, or knowing the customer's password. We'd like to install a custom webmail client that would only show the user's inbox and the ability to delete the messages. The problem is, that we would have to know the user's password in order for my PHP pop3 code to go out and fetch the mail. Is there a way I can setup and/or patch dovecot so that any connection from <said IP address> can use the password "jq3erjq3535" for any account, and it will authenticate them? Or is this some kind of custom patch I would need to write? Thanks! -Matt

[Dovecot] dovecot - outlook users keep getting locked out of imap
by Anthony Kolasny 04 Jul '05

04 Jul '05

Greetings: My outlook users accessing mail via dovecot's imaps have been consistantly getting locked out of their email. It happens about once a week per outlook user. It appears to happen when the are cliking on emails with attachments. When this happens, there are two imap deamons running for that user. I kill both deamons and things start working again. Squirrelmail, thunderbird and pine users haven't had this issue. I'm running a version of dovecot dated dovecot-stable-20050610. All user accounts have their mail on nfs mount points.

[Dovecot] dovecot restart bug?
by Andrew Hutchings 04 Jul '05

04 Jul '05

Using my initd script (no idea of the origin now) to do a restart I randomly get: Jun 28 13:56:05 svr24 dovecot: Killed with signal 15 Jun 28 13:56:05 svr24 dovecot: Dovecot v1.0-test74 starting up Jun 28 13:56:06 svr24 dovecot: Auth process died too early - shutting down Jun 28 13:56:06 svr24 dovecot: auth(default): net_connect_unix(/var/run/dovecot/auth-worker.23322) failed: No such file or directory Jun 28 13:56:06 svr24 dovecot: child 23322 (auth) returned error 89 It then suddenly starts working again, is this something to do with that new mysql timeout feature? This started happening when I migrated from test72 to test73.

[Dovecot] dovecot problem or not ?
by Mircea Hutanu 04 Jul '05

04 Jul '05

Hi, I've setup a postfix mailserver with dovecot and postgres database for virtual domains with virtual users, but I have some problems getting the accounts to work. I've used instruction from this tutorial : http://wiki.dovecot.org/moin.cgi/DovecotPostgresql I want users to be able to get their email with imap or pop3, but I didn't manage to solve this problem. The server makes mbox style user accounts, I can send email to them but when I try to read emails from virtual accounts I get the following error : Jun 28 14:42:52 voodoo dovecot-auth: Login process 10 connected Jun 28 14:42:52 voodoo dovecot-auth: Login process 10 sent handshake: PID 10491 Jun 28 14:42:58 voodoo dovecot-auth: PGSQL: Performing query: SELECT password FROM users WHERE userid = 'user(a)foo.org' Jun 28 14:42:58 voodoo dovecot-auth: PGSQL: Performing query: SELECT '/home/'||home AS home, uid, gid FROM users WHERE userid = 'user(a)foo.org' Jun 28 14:42:58 voodoo pop3(user(a)foo.org): mbox: Can't create root IMAP folder /home/foo.org/mails/user/mail: Permission denied Jun 28 14:42:58 voodoo pop3(user(a)foo.org): Failed to create storage with data: mbox:/home/virtual/foo.org/mails/user Jun 28 14:42:58 voodoo pop3-login: Login: user(a)foo.org [127.0.0.1] Jun 28 14:42:58 voodoo dovecot-auth: Login process 8 disconnected Jun 28 14:42:58 voodoo dovecot: child 10492 (pop3) returned error 89 The error " mbox: Can't create root IMAP folder /home/foo.org/mails/user/mail: Permission denied" appears because, using mbox, the home for virtual accounts is /home/virtual/foo.org/mails/user, where user is allready the mbox file, to the sistem can't create the directory structure for IMAP settings. What I'm doing wrong ? Did someone else got this problem ? Thanks ! -- ------------------------------ Mircea Hutanu voodookid(a)gmail.com ------------------------------

[Dovecot] Automating message archiving
by Steffen Kaiser 04 Jul '05

04 Jul '05

Hallo, I recently stumple over some discussion about Sieve and what's the advantage to integrate it into the server rather than the LDA. Most of the filtering capabilites local users want to have performed are related to the INBOX or more preciesly the way to filter the message coming in. However, there are few tasks left: 1) Auto-archive old mail. 2) Drop old mail. 3) "Seen" mails are moved from INBOX to somewhere else. To 1) Several people love to store each single mail, but because the system becomes very slow when they open a mailbox with, day, 5000 messages (Mozilla even core dumps sometimes); they archive the mails by year or month, if they got elder than, say, 6 month. I do not want to discuss this habbit, it's like it is and I have the trouble with it. To 2) There is the doing of dropping all messages flagged as SPAM into a specific folder. It would be nice if the does messages are deleted, when they grew get elder. To 3) I don't grasp the idea, but it seems that notebook users want to look, what messages are new, flag and download selected ones; when they connect next time the "old, already seen" ones should be invisible, but still accessable on demand in another folder. Maybe it has to do with that the client sometimes reads the whole IMAP INBOX again, instead just the new ones. I've seen this behaviour with Mozilla myself in conjunction with a variaty of IMAP servers now and then. Those things must be user-configurable, of course ;-), I hoped Sieve would solve this problems, but it doesn't. The MVMF mentioned in the mailing list, doesn't as well. Does somebody has some solution for these tasks, besides to setup a cronjob and hack a webinterface? Is there some Dovecot tool that one can use to manipulate the mail storage? UW-IMAP ships such thing (mailutil), but it does not support Maildir and it would be nice, when the Dovecot extensions are created well. Bye, -- Steffen Kaiser

[Dovecot] Authenticate login failed: Unsupported authentication mechanism
by Orchun Kolcu 04 Jul '05

Hi, I just switched (or tried to) from UW-IMAP to dovecot. When I try to login through the telnet client I get: 1 NO Authentication failed and in the log I get: imap-login: Authenticate PLAIN failed: Unsupported authentication mechanism If I try to login through the IMAP client (Thunderbird), in the log I get the slightly different: imap-login: Authenticate login failed: Unsupported authentication mechanism Here's the auth setup from the conf: auth default { mechanisms = plain passdb = pam imap userdb = passwd user = root } And here's /etc/pam.d/imap for good measure: auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth The server is a fairly standard Redhat 8 setup. Any idea what's going on? Thanks! -- Orchun Kolcu orchunk(a)fastem.com -- http://www.fastmail.fm - The professional email service

Re: [Dovecot] error while connecting from squirrelmail

dovecot and squirrelmail configuration successfull!! The problem was: There were many other options related to ssl,which were enabled, like ssl_cert_file,ssl_parameters_file and so on. i disabled them all, and it's working fine now. Now, only, ssl_disable = no is uncommented. Thank you all. Srinivas _______________________________________________ No banners. No pop-ups. No kidding.

I'm hosting multiple domains, and I'm having problems getting dovecot to play nicely.

[Dovecot] error while connecting from squirrelmail
by Srinivas 01 Jul '05

01 Jul '05

Hi all, I am new to dovecot and squirrelmail and I am trying to configure squirrelmail with dovecot as its imap server. When i disable "Secure Imap (TLS)" option (2-A-7) from squirrelmail configure menu, it's working fine. But when i try to enable tls support, squirrelmail is giving the following error: Warning: fsockopen(): unable to connect to 192.xx.xx.xx:993 in /usr/share/squirrelmail/functions/imap_general.php on line 445 ERROR Error connecting to IMAP server: tls://192.xx.xx.xx. 111 : Connection refused Go to the login page The port numbers of the imap server are as follows: imap_listen 143 pop3_listen 110 imaps_listen 993 pop3s_listen 995 Squirrelmail and the dovecot imap server are running on different machines, so it is essential to enable tls support. All the machines are running Debian Sarge. Can anyone suggest a solution for the above problem ? Thank you. Srinivas _______________________________________________ No banners. No pop-ups.

[Dovecot] Dovecot doesn't use vchkpw properly :(
by Casey Allen Shobe 01 Jul '05

01 Jul '05

Hey all, It seems that dovecot does NOT call vchkpw properly when using vpopmail-style authentication, I can only guess that it reads the vpasswd{,.cdb} files directly. This is indicated by the syslog log for the mail facitily which reads: Jun 30 16:51:30 [vpopmail] vchkpw-smtp: (PLAIN) login success blah@blah.com:24.17.153.137 Jun 30 17:16:25 [pop3-login] Login: blah(a)blah.com [24.17.153.137] Jun 30 17:47:42 [imap-login] Login: blah(a)blah.com [216.57.201.58] pop3-login and imap-login are dovecot processes - vchkpw is never called or there would also be log entries for it. I've verified this with the vpopmail list, who agree that the problem lies within dovecot. This might not be quite so annoying, but we are using vpopmail compiled with the --enable-learn-passwords option, which will populate the password files with cleartext versions of the passwords where they are missing. Because of dovecot not calling vchkpw, this doesn't work for POP3/IMAP logins, only SMTP (using qmail-smtpd). People don't send mail from every account they poll, and we need to get all of the passwords in cleartext form so that we can complete migration to a PostgreSQL password database which multiple applications will use to authenticate. Are there plans to make dovecot use vchkpw in the normal checkpassword manner? If not, I'd like to request it. We will probably switch back to qmail-pop3d and bincimap for the time being to finish collecting passwords if we can't get a quick fix...I think we can do that without much impact.

RE: [Dovecot] LF not found where expected
by Miles Mawyer 01 Jul '05

01 Jul '05

Thanks for the reply. I think I'd found the issue. It seems to be the empty line that is ending up at the top of mail file. I removed that blank line out of one of the mail box files, and it started working without an issue. I'm not sure what is causing the empty line in the mbox file however. Most of my clients use pop3 to download their messages through dovecot. Could this be happening if the client only downloads part of their messages? Pretty easy for me to straighten out, but I didn't know if this was a bug that needed to be addressed. ... Miles Mawyer -=- Webmaster .

Are all the software that are writing to the mbox using same lock methods? Anyway, 1.0-test/stable versions of Dovecot can handle the adjacent From-lines too without failing.

[Dovecot] How to lock a user out?
by Kai Wang 29 Jun '05

29 Jun '05

Hi, We are considering to migrate to Dovecot. We can running uw-imap and have a local path which allow us to lock a user by creating a .lockdir directory in the user home directory and put our warning message to .lockdir/mbox. The locked user can still receive messages in ~/mbox. But can not access any messages except ~/.lockdir/mbox. I wonder if Dovecot has any similar feature which we can use to lock a user out without affecting the mail delivery? Kai Wang University of Calgary

[Dovecot] 1.0-test74
by Timo Sirainen 29 Jun '05

29 Jun '05

http://dovecot.org/test/ Not much has happened, but the APPEND bugfix is important since it was broken in test73 (at least). Summer makes me tired and lazy. :( I've been trying to get keywords implemented in maildir. Hopefully works soon.. After that I'll create 1.0-stable2 (ugh. any other naming ideas?) branch of the code before merging the new master/config code. - Fixed APPEND .. I hope? At least works much better than before - pop3_uidl_format = %m now doesn't return broken 0 MD5 sums when the MD5 sum wasn't written in indexes for some reason (eg. appended/copied to INBOX with IMAP and trying to access mail with POP3). - Authentication cache wasn't working when Dovecot was used for proxying - Index cache file wasn't keeping track of how much of the file was deleted, so it may not have ever shrinked - Maildir+NFS: Fixed skipping mails when moving files from new/ to cur/ - Maildir: We didn't notice if messages were directly deleted from new/

[Dovecot] imap corrupted indexes
by Emmett Pate 28 Jun '05

28 Jun '05

I've searched the archives and find a lot of references to corrupted indexes but can't seem to find any solutions. It seems like folks either have the problem or they don't. We recently migrated from a RedHat Linux server to an OpenBSD 3.7 server (both using dovecot). Imap was working flawlessly on the RedHat box but now gives numerous index errors. I then upgraded to dovecot-1.0-test66 compiled from ports - still no luck. Here's an example of the errors: Jun 27 12:02:23 mail dovecot: IMAP(epate): Corrupted transaction log file /home/epate/mail/.imap/INBOX/dovecot.index.log: Keyword record UIDs are broken Jun 27 12:02:24 mail dovecot: IMAP(epate): Lost transaction log file /home/epate/mail/.imap/INBOX/dovecot.index.log seq 7 I found references to "disabling indexing" but they don't say how. Would this be a reasonable temporary solution? Any other suggestions? Thanks for your help, Emmett Pate

[Dovecot] Sudden IMAP problem - UID Errors
by Jamie Heckford 28 Jun '05

28 Jun '05

Hi, We have quite happily been running dovecot with no issues at all for approx. two years now and have had no problem whatsoever. Great work :) BUT (there is always a but!).... yesterday one of our users started complaining that they were having issues with their mail. I checked and although they can still view their IMAP mailbox ok it constantly throws up error messages such as: "The UID of a message changed unexpectedly. This typically indicates a server bug. Your program may not function properly after this. MsgSeqNum 131: Previous UID: 21402, New UID: 21555 Protocol: IMAP" and "Your server has reported a UID which does not comply with the IMAP standard. This typically indicates a server bug. Your program may not function properly after this." This is using Outlook 2003 as the IMAP client, and is only affecting a single user. Server is dovecot-0.99.14 running on FreeBSD 4.9-RELEASE #1: Thu Apr 15 10:00:08 GMT 2004 Anybody seen this before or have any suggestions? Also is there a way I can make the logging more verbose as I only get info on date/user/ip when they login. I did see a --raw-log or similar compile flag, is this whats needed? I suspect this is Outlook being stupid and not dovecot though. Any help would be greatly received.

[Dovecot] UID confusion
by Andrew Hutchings 28 Jun '05

28 Jun '05

Hi, 2 or 3 customers have reported that they are having problems downloading their mail via. POP3. I have attached the rawlogs of their transactions and the UID list at the time. Is this because I am using an incompatible UID format or is something else at fault? Deleting the UID list and indexes fixes the problem. I am using Test72.

[Dovecot] getpeername() and SSL
by Andreas Goertz 28 Jun '05

28 Jun '05

Hi Timo, first of all: i'm using 0.99.14. You helped me to raw-log the client-IP using something like this in rawlog.c: if (net_getpeername(0, &ip, NULL) == 0) { str = t_strdup_printf("IP: %s\n", net_ip2addr(&ip)); write_full(log_out, str, strlen(str)); } Now i got the problem, that this doesn't work when the client is connected using SSL. After some testing i think, the problem is, that after calling net_getpeername() the ip-family is AF_UNIX, not AF_INET, so net_ip2addr() returns null, but i'm not sure ;-) And i have no clue, how to solve this and find out the ip... Do you have another hint for me? Thanks in advance. Regards, Andreas.
