[Dovecot] IMAP Memory Error
by John McAree 25 May '05

25 May '05

Hi, I recently upgraded dovecot on an OpenBSD server from the 0.99.x series to the 1.0-test series to eliminate a problem. That was fixed, however I am now experiencing issues with IMAP(S) connections. The main IMAPS use to the server is via Squirrelmail (many users login with it), however I typically use Thunderbird. The user mailboxes are stored in Maildir format. Basically, moving, deleting or copying mails tends not to work. I have managed to move mails in Thunderbird if the source mailbox is small, and deleting mails usually works in Thunderbird. However, in Squirrelmail deleting or moving results in: "ERROR : Connection dropped by imap-server. Query: COPY 5629 "<dest-mailbox>" /var/log/maillog reports: May 24 23:19:03 orca dovecot: IMAP(jmcaree): pool_system_malloc(): Out of memory The Out of memory error appears when moving mails with Thunderbird, also. I had originally upgraded to dovecot1.0-test66 via a patch supplied by an OpenBSD porter. Today I decided to compile -test70 to see if it was any better. Unfortunately, this issue still exists. I tried upgrading Squirrelmail to the latest (1.4.4 from 1.4.3a), but no luck there. Since it's happening with both it and Thunderbird, though, I don't see it being a client issue. Server is: # uname -a OpenBSD my.hostname.com 3.7 GENERIC.RAID#0 amd64 I'd appreciate any assistance or advice on this issue! Obviously, I'd prefer to not have to downgrade to the 0.99.x series. :-) I'm not subscribed to the list, so please CC me with any replies. TIA, John.

[Dovecot] Auth Issue

25 May '05

I am so confused. Can someone help me out here? I have set it up so that it is to accept login via PLAIN TEXT. I am using Thunderbird to connect, and it will ask for my password (the username is already in the system) I get a pop-up for Enter the password for Username on Domain.com I enter my password (the same I would use to login to FTP) and it fails. Any thoughts? -- Adam Barrett dragen(a)gmail.com

[Dovecot] Simply can't figure it out
by Gaby vanhegan 24 May '05

24 May '05

Hi, I'm having a hideous problem trying to get the latest stable version to work. I've had no success and simply can't pinpoint the problem. Sorry for the rather long email but I've included as many details as I can to help here. I've been trying to install the latest stable version (as of 23rd May 2005) by downloading the tarball from the site to my OpenBSD 3.6 box, and building with these arguments: # ./configure --localstatedir=/var --with-ssl=openssl --with-ssldir=/etc/ssl --without-vpopmail - -without-pam --without-shadow Which builds fine. Here are some files from the installation folder: http://vanhegan.net/dovecot/config.log http://vanhegan.net/dovecot/config.status Here's my configuration file. I only really want to server imaps, but I've turned on imap for debuggering purposes: http://vanhegan.net/dovecot/dovecot.conf And it's running from my inetd.conf: # Dovecot IMAP services 144 stream tcp nowait root /usr/local/libexec/dovecot/imap-login imap-login --group=default/imap imaps stream tcp nowait root /usr/local/libexec/dovecot/imap-login imap-login --group=default/imap --ssl (I'm running on port 144 to not clash with the existing IMAP service on port 143). Now, no matter what I try, I simply can't make it login, or start the process: (restart inetd, dovecot, check they're dead) bash-3.00# kill -HUP `cat /var/run/inetd.pid` bash-3.00# kill -TERM `cat /var/run/dovecot/master.pid` bash-3.00# ps auwx | grep dove root 828 0.0 0.1 84 456 p2 S+ 8:39PM 0:00.01 grep dove bash-3.00# /usr/local/libexec/dovecot/imap-login --group=default/imap F/usr/local/libexec/dovecot/imap-login can be started only through dovecot master process, inetd or equilevant (start dovecot, check it's running, error expected, other imap server already running) bash-3.00# /usr/local/sbin/dovecot Fatal: listen(143) failed: Address already in use bash-3.00# ps auwx | grep dove root 14041 0.0 0.3 212 1012 ??

[Dovecot] Newbie-ish Questions
by Joe Dauncey 24 May '05

24 May '05

Hi, I'm in the process of migrating from local Maildir, to IMAP-enabled Maildir (terms are made up by me). I have my Maildir directories all under $HOME/Mail I have a procmail script that sorts everything into different folders under $HOME/Mail, and leaves the rest in a Maildir folder chosen by me, that I think of as my INBOX. Now, I am assuming that the folder I identify as INBOX is the one that a client will interpret as the INBOX? I really want the INBOX to be one of the folders under $HOME/Mail, but at the moment dovecot only will only consider the folder $HOME/Mail as the INBOX, so I have to send my 'inbox' mail to $HOME/Mail, rather than what I would prefer, which would be $HOME/Mail/INBOX (or something like that). The seting I have in dovecot.conf is: default_mail_env = maildir:~/Mail Is this is the only way, or am I doing something wrong? Should I be using default_mail_env to define the inbox? e.g. with: default_mail_env = maildir:~/Mail:INBOX=INBOX (or whatever my inbox mail folder name is) Maybe I've just got my Maildir folder set up completely wrong, and I'm supposed to accept the Maildir folder itself as the inbox? If so, please just send me on my way ;-) Also, since I don't know much about IMAP, where can I find out what the .subscriptions file is, and what it does, and also all the other files created by dovecot, like the .imap files and the .customflags Thanks, Joe -- Joe Dauncey

[Dovecot] Read-only mail folders
by Chris Wakelin 24 May '05

24 May '05

Is it possible to have folders on read-only partitions in Dovecot 1.0-stable? We have a NetApp fileserver which would probably be accessed via NFS (though iSCSI is possible) and which stores readonly "snapshots" of every directory accessible as .snapshot (but usually hidden from the operating system). It would be very nice to set up a "snapshot" namespace something like :- namespace public { separator = / prefix = "#snapshot/" location = maildir:%h/Maildir/.snapshot/nightly.0 hidden = yes } so that users could recover messages from say yesterday's version of their mailbox. Unfortunately, Dovecot always seems to want to write to the directory, even when indexes are stored elsewhere (as recommended with NFS anyway, I think) using INDEX=whatever in the location line.

[Dovecot] Stability
by Casey Allen Shobe 24 May '05

I am currently using Dovecot 0.99.14-r1 as provided by Gentoo, in a Qmail + VPopmail configuration. I am curious as to how to configure it to ensure the most stability, as it serves >1000 clients. I would rather disable any indexing that give small speed improvements if they are not known to be stable. Advice?

[Dovecot] 1.0-stable loses flag changes sometimes?
by Chris Wakelin 24 May '05

24 May '05

I've been struggling with an odd bug in the latest 1.0-stable (20050427) release. Sometimes Dovecot seems to forget that a message has been read or deleted and marks it unread (or not deleted). As far as I've been able to determine, it seems to happen when 1) There have been several recent deliveries 2) Possibly some of those deliveries are of multiple messages 3) Possibly they are read very quickly (say only a second for each message) 4) Folder is an mbox (haven't tried Maildir) I've seen it with Thunderbird mostly, but did manage to recreate it once in "telnet" - the debug IMAP client ;) - using "IDLE" "FETCH" and "STORE msgid +FLAGS (\Seen)" commands. I managed to catch it in the act with one Thunderbird session, and it seemed to occur when Thunderbird, for some reason, issued an IMAP "CHECK" command. In this case it issued an extra "* 710 FETCH (FLAGS (\Recent))" response (the new messages had been msgid 711-715). Incidentally, Thunderbird seems to do a "STORE .. +FLAGS (\Seen)" command even though this is implicit the "FETCH .. BODY[..]" command (and it gets informed of the flag change in the response). I've tried and tried to find a "formula" for re-creating the problem "on demand", but it only goes wrong occassionaly. My guess is it's some sort of timing thing with mbox sync (BTW we have "mbox_dirty_syncs = yes" and "mbox_very_dirty_syncs = no"). Has anybody else seen this? I'm hoping to roll out this version to our wider group of testers soon and would like to get this issue solved first if possible (it counts as an annoyance rather than a serious problem).

From what i have tested this it's working but only if you want to fallback to another supported password databases different that the privios.

[Dovecot] (no subject)
by Brent Clark 23 May '05

23 May '05

Hi all I have just finished installing / configuring my dovecot IMAP server. Im seeing something weird happing. It seems my Winblows Outlook users are experiencing a problem whereby when they delete an email, Outlook puts a line though the email, but the mail does not delete. Im not sure if this is a an outlook problem or a dovecot IMAP problem. I cant see anything in the conf file to suggest that it is a IMAP problem. If anyone has any tips or advice, it would greatfully be appreciated. Kind Regards Brent Clark

[Dovecot] utime() failed: Value too large for defined data type
by Brian Hechinger 22 May '05

22 May '05

i have recently rebuilt dovecot on my mail server as i wanted to add SSL support for it. well, my OpenSSL libs are 64-bit, so what they hey, i'll build dovecot 64-bit as well. worked just fine, no issues at all. the setup is: Solaris 9/SPARC Sun C compiler Dovecot 0.99.14 after rebuilding it 64-bit, i now have a small problem however. I cannot save messages to IMAP folders from Mail.app on OSX 10.3.9. OE6 and mutt work fine, no problems there, but when I try to save a message from Mail.app, it tells me it couldn't save the message and i get the folloing in my log file on the mail server: May 19 16:24:37 wiggum.4amlunch.net imap(paula): [ID 702911 mail.error] utime() failed for /usr/home/paula/Maildir/.Sent Items/tmp/1116534277.P10885Q0M105223.wiggum.4amlunch.net: Value too large for defined data type does anyone have any clue as to what could be the cause of this? i would say simple 64-bit uncleanliness issue, but why doesn't it also affect OE6 or mutt? there is some way that Mail.app accesses IMAP that is specifically tickling this problem. thank you very much for your time, and if there is any other information you might need to track this down, please ask and i'll get it right away. -brian -- "I fear death only slightly more than I hate my life." --8-bit Theater

[Dovecot] dovecot deliver question

Hi Timo, How much of the code base is shared between dovecot-lda and the dovecot CVS? I'm asking because when I tried out 'deliver' a few weeks ago I was seeing all sorts of nasty index corruption errors in the logs...and obviously lots of fixes have gone into core dovecot (but haven't seen many go into dovecot-lda) Reuben

I've been searching, and I can't find any rpms of dovecot stable for RHEL 4. Does anybody know where I can get one? Ever since we went from IMAP-UW to Dovecot, we've been having frequent problems with mbox corruption, and I've read that 1.0 fixes many of those types of problems.

[Dovecot] Corrupted transaction log file, dotlocks..?
by John and Catherine Allen 16 May '05

16 May '05

I'm new to Dovecot but I've been able to get it up and running on a test basis without too much difficulty. I'm running dovecot-stable-20050508 with maildir, under Linux (an old Gentoo setup that's been stable for about 2,5 years). Mail client is Thunderbird. However, in the course of experimentally copying the accumulated household email (95000 emails from the last 10 years) from the existing IMAP server (UW-IMAP) using imapsync, I'm seeing some problems. While copying the 1000 or so messages from the main INBOX, Dovecot seems to hang after 50-100 messages and the following lines appear in the server log: May 15 18:45:21 [dovecot] IMAP(allen): utime(/home/allen/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 15 18:45:21 [dovecot] IMAP(allen): Our dotlock file /home/allen/Maildir/dovecot-uidlist.lock was deleted May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 [...20 identical lines deleted....] May 15 18:48:27 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] IMAP(allen): Transaction log file /home/allen/Maildir/dovecot.index.log: marked corrupted I can restart after deleting the dovecot files in ~/Maildir, but the problem recurs. In other folders I've been able to copy large numbers of emails successfully with imapsync. I've not experienced any problems while accessing the folders with Thunderbird.

[Dovecot] new-attrib lost when calling through pop3
by Marten Lehmann 15 May '05

15 May '05

Hi, I noticed, that all messages are moved from new/ to cur/ (using maildirs) after the authentication in pop3, even before the list command. I'm working with 1.0-stable-20050426. Why is this done? Shouldn't a message keep it's new-attrib as long as it isn't retrieved? This is how it worked with qmail-pop3d. Through imap, it works correctly. It's just sad if I can't distinguish between older and new emails with imap, just because I logged in through pop3 shortly before. Regards Marten

[Dovecot] dovecot through NFS
by Marten Lehmann 14 May '05

14 May '05

Hello, as our mail server load increases every day, I plan to scale the single mailserver in differnt units: 1x big storage server for all mailboxes, folders exported through NFS 1x smtp for mail-in (queue local, messages on storage server) 1x pop3/imap to retrieve the messages (config local, messages on storage server) Since we're using maildir only, there's no problem to get the messages into the mailboxes. But what about dovecot for retrieving them? NFS will be v3. Is locking still a problem with it? Might the indexes get corrupt? Regards Marten

[Dovecot] Fedora Core 3 and Mail.app problems
by Gordon Turner 14 May '05

14 May '05

Hello, first thanks for all the work, I appreciate the attention to security :-) I have a performance issue I am trying to solve. On my new server it would appear that synchronizing changes between the client and server is taking longer then my previous setup. I have recently upgraded from my old server to a new home (the basis for my comparison), From: - Redhat 9.0, uw-imap, using self-signed ssl certificates, on an old p-II. - Only one email user (me), about 40 mail folders with a few dozen messages in each. - Performance was never an issue, Mail.app took maybe 20 seconds to sync up minor deletes etc. To a new home: - Clean install of Fedora Core 3 on a p4, dovecot-0.99.13-3.FC3. - Copy of /home/gturner/mail directory to new server, ie existing mbox format from uw-imap. - Recreated new self-signed certificates on new server, manually added the self-signed certificates, connected with no problems. - Mail.app client, on OS X 10.3.9 (no Tiger yet). I deleted the account on Mail.app, and created it again, the first login/sync took a long time, which was expected. However after that, I noticed that when I first connect or delete a file the sync is slower then the old setup (FYI, I keep "Automatically synchronize changed mailboxes" checked on Mail.app). A result of this appears to be some corruption of some mailboxes, only one or two, nothing valuable. For example, I delete a file and then clear the trash while things are still syncing. So my current solution is to be patient. :-) Any suggestions? I know that I could covert everything over to maildir, but I would like some feedback to see if this would be reasonable. I also noticed that initially there are 3 'gturner imap' threads and the syncing seems to be flying along. Then the thread count goes to 5 or 6 and sync starts to crawl. I looked for a way to limit the number of spawned threads, but only saw stuff about 'waiting' threads or reference to 1.0. I have attached my dovecot.conf for reference. Any help is greatly appreciated, Gord Turner.

[Dovecot] Outlook strange behaviour...

13 May '05

Hi all, I have a Dovecot server(dovecot-0.99.14) running with IMAP support, running on a Fedora 2 system. Outlook (2003) users receive duplicate mail, "the" second mail doesn't have a title, when clicking on it, we are getting "non fully downloaded" error message. When deleting the "orignal" mail, all duplicates gets deleted too. Any ideas?

[Dovecot] problem with test69
by Cor Bosman 13 May '05

13 May '05

Hi all, I noticed a problem with test69. I can recreate it with the following steps: - create a folder - copy about 200 emails from INBOX to this folder The copy succeeds, I can see with rawlog that it actually moves the 200 emails around. I can see on the spool that there are 200 emails. This is maildir, with spool over NFS. Now I immediately select the new folder. I now see only a part of the emails reported. And with rawlog I indeed see something like: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft Junk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft Junk \*)] Flags p ermitted. * 158 EXISTS * 158 RECENT * OK [UNSEEN 3] First unseen. * OK [UIDVALIDITY 1115970206] UIDs valid * OK [UIDNEXT 217] Predicted next UID 2 OK [READ-WRITE] Select completed. My client faithfully reports 158 instead of 200. If I now close/open my client, and re-select, I see 200. This I can reproduce with several different clients, but its pretty obvious it isnt a client issue. I also reproduced this with different users. Anyone see this also? NFS issue? Cor

[Dovecot] dovecot 1.0-test69 io hangs
by Jens Laas 13 May '05

13 May '05

I've been testing test69 with pop3 (under Linux and with mbox). I began testing with a large inbox (11000 mails) and it seems the communication between dovecot and the mailclient (evolution) stalls after 1000-2000 messages transferred. I've looked in to the (non-trivial) io functionality of dovecot. What I see is that io_loop_handler_run() in ioloop-poll.c does not signal any more data (and eventually the whole thing timeouts). Evolution downloads the mailbox fine via qpopper. I tried turning on rawlog: mail_executable = /usr/libexec/dovecot/rawlog /usr/libexec/dovecot/pop3 I cannot find any logfile.. I must be missing something. Any help or ideas ?

[Dovecot] "shared mailboxes"

Hello, After a long search I've almost settled on dovecot as a pop3 and imap server. I have just one problem.. Rather than have a list support(a)company.com, I'd like to have a shared mailbox.

[Dovecot] 1.0-test69
by Timo Sirainen 11 May '05

11 May '05

http://dovecot.org/test/ - Several mbox fixes, upgrade recommended for test68 mbox users - Possibly fixes some IMAP hangs where Dovecot just stopped replying - Fixed delay-newmail workaround. It was badly broken before. And somewhat off topic advertisement: I got a bit distracted from Dovecot a week ago when a guy started mailing me about wanting to write an irssi2 client as a project to learn Ruby. Half a year ago I had written a semi-working irssi2 server but I got stuck with it because I wasn't interested about writing client for it. Now that the client actually works, irssi2's development has kind of exploded :) Irssi2 is a bit related to Dovecot too, in that it'll be integrated with it more or less tightly to provide instant messaging support. Nothing prevents extending irssi2-protocol to support all other kinds of realtime events either, for example to send new mail notifications. If you're interested, see: http://main.irssi.org/projects/irssi2.html And for the lazy, here's the introduction copy&pasted: Shortly put, irssi2 is to instant messaging what IMAP is to mail. You can safely exit your irssi2 client, and irssi2 server just keeps on going. When you connect back with your client, you can see all the discussion that happened while you were away (and even older discussion, too, if you want). You can also use multiple clients even at the same time, so you could for example keep one client always open at home and still be able to check what's going on with your mobile phone. Irssi2 clients are encouraged to keep their configuration in server side, so nothing should prevent you from temporarily using another irssi2 client from your friend's home with no other configuration needed than irssi2 server's address, your username and password. Irssi2 is designed to support multiple chat protocols (IRC, SILC, MSN, ICQ, etc.) but without ignoring hardcore IRC users. That means that unlike all other similar attempts (such as Jabber), irssi2's client-server protocol will actually allow fully featured irssi2 IRC client to be written with no compromises (but still the same client can be used to talk to MSN and elsewhere). Note that irssi2 isn't trying to replace IRC servers (yet ;). irssi2 server simply connects to normal IRC servers just as a regular IRC client. To prevent mixups with these terms, IRC servers are usually called "gateways" in irssi2.

[Dovecot] Dovecot Sendmail Maildir

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably being anal, but I want to keep my MTA the same across the board. Does anyone here use sendmail + dovecot + maildir? if so what's the best way of going about this? Gabe

[Dovecot] Standard dirs
by Claudio Succa 10 May '05

10 May '05

Hi, thank to developers for such a flexible imap server. Is solves succesfully my needs to have a single passwd file for clients accessing both imap/imaps and pop3/pop3s protocols (on a diskless mail/web server with NFS maildirs and NFS indexes!). My question: With 1.0-test68 I have to set login_dir=/var/run/dovecot-login (just a dir not under /var/run/dovecot) instead of /var/run/dovecot/login. I guess that imap-login (running with uid=dovecot) can't access /var/run/dovecot/login if it is under /var/run/dovecot because it is set with permission 0700 and uid=root by dovecot.

[Dovecot] start_tls on the user and password ldap connection
by Farkas Levente 10 May '05

10 May '05

hi, it seems when dovecot use ldap user and password databases it's not possible to use tls connection and certificate with the ldap connection. wouldn't it be possible to use the same certificate on the ldap connection as used in the ssl_{cert,key}_file parameters in the dovecot conf (or would be possible to use it's own cert in the ldap conf file? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] trouble getting digest-md5 & ldap working
by Udo Rader 09 May '05

09 May '05

hi, I am trying to set up dovecot with digest-md5 as authentication mechanism and openldap as passdb. My problem is ... that I just can't get it working. PLAIN authentication works as expected, but no luck with digest-md5. An excerpt from the two configuration files: dovecot.conf: --------CUT-------- auth = default auth_mechanisms = plain digest-md5 auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf --------CUT-------- dovecot-ldap.conf: --------CUT-------- user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) default_pass_scheme = plain --------CUT-------- My dovecot installation with plain authentication and OpenLDAP has been quite mature for a long time, so I doubt that it is an issue with openldap. >From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required to have plaintext passwords in the DIT, but that does not solve anything. syslog tells me this: dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply So any ideas on where I went wrong?

[Dovecot] transparent proxy
by Mark E. Mallett 09 May '05

09 May '05

I'm excited to see that dovecot 1.0-test series supports transparent proxy, but that excitement is muted by: - the recommendation to avoid 1.0 at present; - the requirement to use SQL authentication. I guess I could ignore the first, but the second is sticky. How hard would it be to hack a different sort of proxy server cue into the authentication? Perhaps one of: If authenticating via passwd, use a gid as an index into a server table (or perhaps have the group name be a server name), If passwd authentication fails, try a starting the proxy to a specific other server and see if one can log in there. Or something else.. I dunno, I'm just looking not to install a SQL server just for this. mm

[Dovecot] index file corruption
by Andy Pastuszak 09 May '05

09 May '05

Hello everyone. I am new to the list, so forgive me if this has been discussed already. My configuration is as follows: Fedora Core 3, fully patched through yum through today. Dovecot 0.9.9.13 Postfix 2.1.5 Using Maildir with Mail stored in ~/Maildir My issue is that, for some odd reason the inbox file index gets corrupt, There is no rhyme or reason as to why it happens or when, but a simple rm -rf ~/Maildir/.INBOX fixes everything (I assume because Dovecot rebuilds the index file.) Has anyone else on the list seen this? Is there some workaround for it? Andy

[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Test68 and Namespaces
by Jim Summers 08 May '05

08 May '05

Hello List, I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly. So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces. But I am seeing an error pop up in my maillog file when exiting the client, it is: ============================================ May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6 ============================================ Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have: ------------------------------------ namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } ------------------------------------ All seems to work except the message showing up in the logs. My goal/setup is to provide: 1. mbox delivery in the mailspool(/var/mail) from sendmail 2. access to existing ~/Mail/ mbox storage. 3. ability to begin setting up / migrating to maildir in ~/Maildir Is my namespace config above overkill / borken / wrong? Ideas / suggestions on this would be greatly appreciated. Environment: Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

[Dovecot] test-68 coredump
by Gregory Bond 08 May '05

08 May '05

I've tried upgrading from test-51 to test-68, with mixed results. It seems to fix the problem I had with imap and Thunderbird getting confused and not showing headers or body for some email. But something in dovecot is coredumping when I select certain mailboxes. Thunderbird just hangs when you select that mailbox, and mutt gets an EOF on the imap socket while "fetching message headers". Other mailboxes seem to run OK. The failing ones _might_ be empty or have only 1 message in them. Removing index files doesn't help. There is a core file in /var/run/dovecot, and file(1) says it's from dovecot-auth, but GDB can't make sense of the core with that executable, and the login has well and truly run when the core happens. (The core doesn't seem to be from the imap process either.) Any clues how I might debug this? [Solaris 2.8, gcc-3.3, dovecot test-68, imap+Maildir, Thunderbird 1.0.2 on OSX and mutt on Solaris]

[Dovecot] quota-command?

08 May '05

Hello, if you log in at hotmail.com, gmx, lycos or yahoo, you can see something like "using 1.4mb of 250mb total". Is there any IMAP command to check to current quota usage? Our webmail-interface will not have access to the filesystem to summarize the size of each file, so an IMAP-command would be great. I don't know if this would be a new feature or just part of the Maildir++ quota-system, that is not yet supported by dovecot. Regards Marten

[Dovecot] Migrating from courier-imap to dovecot
by Odhiambo Washington 08 May '05

08 May '05

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I am running dovecot in IMAP only mode. I did put default_mail_env = maildir:~/Maildir in dovecot.conf, then for one user, I did the following: cd ~wash/Maildir cp courierimapsubscribed .subscriptions # Then I edited to remove "INBOX." cp courierimapuiddb dovecot-uidlist The permissions are right, but when I login as this user, I don't see all the folders that had been there before when he was using courier-imap!! When I login to the web interface (we use Squirrelmail) and go to the Folder options, I can't see any folders to subscribe to either! Now my questions: 1. What am I overlooking?? 2. Does someone have a script that can be used to automate the copying of courierimapsubscribed to .subscriptions and that of courierimapuiddb to dovecot-uidlist, and the editing to remove the "INBOX."? I am sure I really don't have to reinvent the wheel, no? Meanwhile I am hitting google, while waiting for your answers.

[Dovecot] How to check for keywords in IMAP store?
by Steffen Kaiser 08 May '05

08 May '05

Hello, I'm checking my way to migrate from Courier to Dovecot. Wiki says that "there's currently no easy way to migrate them [the keywords]". Frankly, I lack the information to check if some client is using keywords at all. More importantly, is it OK to assume that when SELECT INBOX returns no \* in OK [PERMANENTFLAGS ...] that the IMAP server does not allow keywords at all?

[Dovecot] Setting location for indexes
by dovecot.7.signal11＠spamgourmet.com 08 May '05

08 May '05

We have NFS-mounted user directories which cause significant problems with stale file handles: dovecot: IMAP(uid): fstat() failed with file /home/uid/mail/.imap/INBOX/dovecot.index.log: Stale NFS file handle (a) why can't it just close the file and re-open ? (b) is there a way to specify with the 'default_mail_env' (or in some other way) the location of **only** the indexes (and let dovecot autodetect all else?). I have already tried 'mmap_disable = yes', but that does not solve the problem, and if I set 'default_mail_env = INDEX=/var/spool/mail/INDEX/%u', I get errors like: IMAP(uid): Failed to create storage with data: INDEX=/var/spool/mail/INDEX/uid I don't want to specify mbox:~/mail/ or mbox:~/Mail/, because some users have one and some the other.

[Dovecot] disabling indexes?
by Marten Lehmann 02 May '05

02 May '05

Hello, I recently had the problem, that an index was corrupt. Thus, messages haven't been listed (talking about POP3), but still remained in the filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice that the index is corrupt and didn't rebuild it. The problem is, that a user can't delete messages through POP3 which aren't listed by dovecot. If the maildir size increases, the arrival of new messages will be blocked because the mailbox is full. And the user has no chance to delete it. Regards Marten

[Dovecot] Blank lines in mailboxes
by Jakob Curdes 30 Apr '05

30 Apr '05

Hello, we use dovecot on a regular basis. Sometimes I end up with a user telling me he does not get mail. When I look after the problem, I always find leading blank lines in the mbox file. We are using postfix with dovecot and amavisd as spam scanner. Amavisd never accesses the mbox files directly so this can be ruled out. I suspected procmail but now it happened also with accounts where no procmail is active. I found only a list thread where this happened always, i.e. it was a configuration error. (Meaning the mailbox was correct but dovecot would not read it). Here ist is only occasionally and therefore hard to track . Does anybody have the same problem or has hints to a solution ? We are running postfix 2.1.4 and dc 0.99.10.6 ; just now I am upgrading to pf 2.2.2. and dc 0.99.14. Yours, Jakob Curdes

[Dovecot] Fresh Dovecot Install
by GPL 29 Apr '05

29 Apr '05

Working on an RH9 box. Did not use yum. Downloaded the "dovecot-stable-latest.tar.gz". Uncompressed it, downloaded and installed gcc. Ran the following: ./configure make sudo make install Seemed to have done its thing. I'll admit I am not well versed in using "make" or compiling anything. When I install I usually use yum on fedora machines. This one being an RH9 machine I have plugged yum into the fedora legacy project and it did not let me install dovecot via yum. So I opted for this route. Regardless, if I run 'which dovecot' I see "/usr/local/sbin/dovecot" However now I do not seem to be able to see it run. I get nothing when I: rpm -qa | grep dovecot ps aux | grep dovecot service dovecot status SO AM HAVE MISSED SOMETHING! Is there another script I need to run? Suggestions welcome. Thanks, George

[Dovecot] dovecot 0.99.xx to 1.0-stable how-to?
by Rich West 28 Apr '05

28 Apr '05

I realize that there have been some big changes in features and configuration file settings between 0.99.xx and 1.0-stable, so when I went to perform an upgrade on our testing server, I carefully combed through the configuration files and matched up everything I could. I fired up dovecot-1.0-stable and was pleased to see that it was happily running. I attempted to connect to it, and discovered that it wasn't listening to any ports.. then I realized that the app had crashed due to a typo in the config file (oops). Fixed that, started it up, and it was happily running and listening. However, it wouldn't authenticate any users.. Backing down to the 0.99.14 version that we had installed allowed for authentication (against ldap) to work just fine.. Is there anything that I should be looking for within the dovecot-1.0-stable that is dramatically different in regards to user authentication? -Rich

I don't know enough to say either way. Maybe I'll take a closer look after I've finished delving into Sun's RBAC. As for the code changes, from memory the UID checking stuff is all in the one place ( in 0.99.14 it seems to be src/lib/restrict-access.c ). I'm not sure about 1.0... we'll move to that when we can have custom flags :) -- Curtis

[Dovecot] cutting everything after @
by Juraj Bednar 27 Apr '05

27 Apr '05

Hello, I am migrating one server to dovecot. The only problem is, that users have logins with @domain as part of their user name. I want to use pam auth (for other reasons, if only for dovecot, I would use mysql, but I need the same password db to be used for other services, like samba). Is there a way to allow this type of login? Just cut everything beginning with @. I can change the source code, but then I don't get nice automatic upgrades. Or can this be done easily with PAM? Thanks, Juraj.

[Dovecot] Shared mailboxes and accessing MailDir not through IMAP
by Steffen Kaiser 27 Apr '05

27 Apr '05

Hello, I'm testing Dovecot that is part of Debian/sarge (v0.99.14-1). So far so good. I have migrated some mailboxes for testing with success and seems that everything works fine. One thing I do not figure out is, what to do about shared mailboxes, which are the very reason of searching for an alternative IMAP server, The Wiki states that there is some sort of shared mailboxes, based upon symlinks. Well, but since which version actually?? The Changelog stops at 2003-11-08 21:12 ? What I need is a mailbox (maildir) for a contact address (not a real shared mailbox, but several users shall be able to read a mail and delete it after processing). For this, one needs write permission to the mails therein only, the MDA takes care of to make the mails readable for the group. It would be good to see, if somebody had answered a mail already, but that's not required. What I tried is this: I setup all Unix-permissions of the folders (. cur new tmp: u=rwx,g=srwx) and their parents (u=rwx,g=x). Then I placed a symlink into the maildir of all users. Each user caches the INDEXes into an individual /var/ directory, not in the maildirs themselves. (BTW: I wonder why I need to give the group write permission to the base directory '.'). The mailbox shows up and is read-write. Now I wonder, what impact I'm to expect here? Esp. "The only problem is that currently everyone's message flags would be shared as well." (quote from a message of a thread taken from the Wiki) Then there is http://dovecot.org/pipermail/dovecot/2003-March/001113.html the third item will apply to my situation, I guess. MailDir is (sort of) expected to be read by mutt directly, for instance. Because the mailboxes are located within the users home directories, some of them do this. Do this item mean that Dovecot is NOT expecting that mails are deleted in any other way than through itself? Otherwise Dovecot would find a change in the mailbox and rebuilt the index file regardless whether the change had been originated by another IMAP client or by directly manipulating the maildir. Bye, -- Steffen Kaiser

[Dovecot] local users + virtual domains
by Micha Silver 27 Apr '05

27 Apr '05

I'm redesigning our mail server which holds several hundred mailboxes - most are local system users and some are virtual domains that we host. I understand that the 1.0x stable release allows for multiple auth mechinisms, so that I could use both PAM for local users and a passwd-file for the virtuals. If I want to stick with 0.99x can I mix and match in a single passwd-file the username/passwd for both local and virtual users? In dovecot.conf I'd have something like: default_mail_env = maildir:%h/Maildir auth-userdb = /etc/dovecot/passwd-file auth-passdb = /etc/dovecot/passwd-file then in passwd-file I'd enter: # local users localuser1:<passwd>:501:501::::: localuser2:<passwd>:502:502::::: ... #virtual domains virt1(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir virt1(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir ... Would this combination work? Thanks, Micha

We're using procmail to deliver mail and dovecot as the imap server. Imap access is sometimes through UW-imap on the same mailboxes. We keep the index files on the NFS server and are using mbox format. I am only running this on one server at this point, so you could see other problems if it is run on multiple servers. Procmail is run on several servers. We're probably testing around 50 mailboxes, some quite large. I haven't seen any corruption of the mboxes and some of them get hit pretty hard. >From my experience, I wouldn't call it "unreliable".

[Dovecot] Track when user last checked mail
by Del Stoliker 27 Apr '05

27 Apr '05

First off I've just got to say thanks. We just upgraded from UW to Dovecot migrating from mbox to maildir. Wow, what a difference! Load average used to hang around 5.0 during business hours and could get up to 20+ on a bad day. Now we rarely break 1.0! I'm wondering if there's a way to keep track of the last time a user checked their email and whether they checked it using POP or IMAP. We're trying to gather statistics on what protocols our users use and find accounts that haven't been checked for a long time. We used to be able to do some of this with the finger command and the user's mbox. I found a script called "mfinger" that works better with Maildir, but it's designed for Courier. Any ideas? Thanks!

[Dovecot] docecot and procmail?
by Dan Stromberg 27 Apr '05

27 Apr '05

Is dovecot still considered unreliable when combined with NFS? Is this true for mbox only, or Maildir as well? If dovecot Is still considered unreliable with NFS, how about having a dovecot mode that would chain into procmail for delivery, so that dovecot doesn't (necessarily) have to reinvent that wheel? Thanks!

[Dovecot] Why is "UIDVALIDITY changed" fatal?
by Chris Wakelin 27 Apr '05

27 Apr '05

I've got several users testing Dovecot IMAP at the moment, but some of them are also accessing their mail via UW-IMAP at other times. (I've warned them about accessing the same folder simultaneously via UW-IMAP and Dovecot!) In addition, we have special folders "AutoSpam" and "Trash" that pruned using Washington's "mailutil" automatically every so often. Of course, Dovecot's indexes will become invalid in such cases, but they seem to get rebuilt automatically OK. However, in some cases UW-IMAP seems to change the UIDVALIDITY value (not sure why!) and when Dovecot tries to sync it notices this and gives up with a fatal error on opening that folder. Opening the folder a second time is then OK. I was wondering why Dovecot can't just rebuild the indexes silently in such cases (which seems to be done by returning "0" from the mbox_sync_loop() routine)?

[Dovecot] Basic configuration problem "not a directory"

When logging in (which I can do successfully) my connection is dropped, and the following is outputted to my dovecot log: dovecot: Apr 26 09:56:52 Fatal: chdir(/bin/false) failed with uid 513: Not a directory dovecot: Apr 26 09:56:52 Error: child 27345 (imap) returned error 89 .. But I'm certain the relevant directories exist.

I have configured fetchmail to fetch my mail from my ISP's POP3-server. I have set up procmail to filter messages and deliver all non-filtered messages to the folder ".IN-catchall/" in "$HOME/Maildir" After sending some test messages the "Maildir" folder in my home-folder looks like: m8ram@medion:~$ tree -a Maildir Maildir |-- .IN-catchall | |-- cur | |-- new | | `-- 1114356268.8424_0.medion | `-- tmp |-- .IN-testing | |-- cur | |-- new | | |-- 1114354955.6900_0.medion | | `-- 1114356175.8292_0.medion | `-- tmp |-- .INBOX | |-- .IN-testing | | |-- cur | | |-- new | | | |-- 1114354955.6900_0.medion | | | `-- 1114356175.8292_0.medion | | `-- tmp | |-- .imap.index | |-- .imap.index.data | |-- .imap.index.log | `-- .imap.index.tree |-- .customflags |-- IN-catchall |-- cur |-- new `-- tmp 16 directories, 11 files Because I have been using the mbox format to test dovecot so far I had to modify my dovecot configuration but no matter what I try none of the messages above appear in evolution or thunderbird.

hi, i'd like to use dovecot to authenticate from ldap. in ldap each user has it's uniq uid and gid. unfortunately with postfix we can't use uniq uid/gid since in this case we have ot create all user's home in advance. so we decided to use uniq uid and a common gid in postfix since in this case postfix can create new users maildir and deliver new mails. so i'd like to use everyone's own uid in dovecot, but a common gid (same as in postfix). but how can i do so? i read the wiki, but the problem is if i use: auth_userdb = ldap /etc/dovecot-ldap.conf then i have to define ldap attrib name in dovecot-ldap.conf: user_attrs = mail,,,uid,uidNumber,gidNumber what should i use in the last field in user_attrs? or it's not possible with dovecot to define this? i'd be very said in this case:-( any advice? thanks in advance. yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] libexecdir and localstatedir problem
by Marten Lehmann 26 Apr '05

26 Apr '05

Hello, I'd really like to define the finale libexecdir and localstatedir through the configure-script. But the Makefiles are rewriting them. Not $libexecdir is used, but $pkglibexecdir. And $pkglibexecdir is always defined as $libexecdir/dovecot. But I don't want this trailing "/dovecot". Same with localstatedir. I want dovecot to use a certain path. But to this path, a "run/dovecot" is appended. I surely could build some patchfiles to change the Makefiles. But it would be easier, if you could add a new directive --pgklibexecdir to the configure-script. I don't know where the "run/dovecot" is defined, but it would also be very fine to set it in the configure-script (specially when upgrading to new releases) instead of defining them all in the dovecot.conf (base_dir, login_dir). Regards Marten

[Dovecot] 1.0-test68 released
by Timo Sirainen 26 Apr '05

26 Apr '05

http://dovecot.org/test/ Recommended update, has had a lot of testing today. No new big features. Changes: - LDAP authentication should work finally? - Some header lookup fixes that should fix sort/threading issues - Don't crash with 0-byte size mboxes - Transaction log fixes. Also rotate .log file to .log.2 file, allowing more history and less "transaction log file lost" messages. - SEARCHing multiple headers might have crashed - mbox: When first message was expunged we might have gotten "uid-last unexpectedly lost" errors. - recent flag counter wasn't updated in index file header always even if the recent flags were removed - UIDVALIDITY changes are handled more transparently - Added --rundir configure option (not actually tested, does it work? :) - etc.

[Dovecot] INBOX can't be deleted
by Marten Lehmann 26 Apr '05

26 Apr '05

Hi, surely it can't and it shouldn't. I'm just wondering why a check for "INBOX" is done in src/imap/cmd-delete.c AND src/lib-storage/index/maildir/maildir-storage.c. The first is clear because it gives an imap-error to the client. But for which case is the check in maildir-sorage.c? Just to be absolutely sure? The reason for me to ask is, because I need to disable deletions for five folders: Drafts, Infected, Junk, Sent and Trash. A certain webmail-interface and spamfilter will rely on these folders, so nobody shall be able to delete or rename them. First I placed the checks in cmd-delete.c. Should I place them in maildir-storage.c additionally? In normal circumstance, the check in maildir-storage.c should never be reached, right? Regards Marten

[Dovecot] Dovecot Stable (or: When is 1.0 coming to a server near you?)
by Rich West 26 Apr '05

26 Apr '05

I'm mainly just curious, but what version of dovecot is considered to be stable enough to be running in a production environment? We're running the 0.99.13 version shipped with FC3 and, while experiencing great performance gains over UW-IMAP, we have hit a couple of snags here and there (random and infrequent characters at the beginning of a mailbox, periodic duplication of a message here and there, etc). I figure we should upgrade to something a bit more current, but I am not sure what the "recommended" verion would be.. Also, perhaps more important, what's the roadmap to getting 1.0 finalized? What's the timeframe? :-) -Rich

However, I'm still experiencing a segmentation fault with today's snapshot of -stable, as shown in the following gdb backtrace. [I'm still running FreeBSD 5.3] Can you see where it comes from ?

[Dovecot] Limiting IP range access
by Luigi Rosa 25 Apr '05

25 Apr '05

First of all, MANY compliments for this fantastic software. Now the question: is it possibile to limit the access to dovecot (or a single service) to a specified range of IPs? Basically, I am thinking about an IP-based ACL. Thankyou in advance. Ciao, luigi -- A beer delayed is a beer denied.

[Dovecot] Quota
by Timo Sirainen 25 Apr '05

25 Apr '05

If anyone's interested about implementing quota code for Dovecot (there were a few of you before! :), now it's finally your chance to do it quite easily. With the API changes committed today to CVS, it's now much easier to write plugins that modify mail-storage behavior. So, I finally fixed my half-working quota plugin that had been lying there for a while. It implements the RFC2087 quota commands for IMAP, a generic quota API that should allow pretty much any kind of quota implementation, and the actual quota limit checking for saving and copying mails. As an example there's an implementation which just scans through all files in a directory and sums their sizes. Currently it can be made to work only when starting from command line, eg.: export QUOTA=~/mail:storage=1024 export MODULE_DIR=/usr/local/lib/dovecot/imap ./imap The QUOTA variable is passed to the quota implementation. In this case quota-dirsize reads it, figures out that ~/mail is the directory where to count the files, and 1024kB is the maximum for quota. I think I'll change the master process code so that any unrecognized varibles that come from userdb are fed to imap/pop3 processes. That way you could simply make the userdb return the quota value (and set other user-specific settings as well). Available from: http://dovecot.org/patches/1.0/quota.tar.gz Unpack under dovecot/src, compile command is at the beginning of quota-plugin.c I'm still wondering where this code should be placed. Maybe the core implementation should be built into Dovecot, while the different quota implementations would be plugins? ..And even better would be if Dovecot's build process was modified so that it's possible to specify with configure script what to compile in and what to compile as plugins.. Anyway, comments welcome, Maildir++ implementation welcome, other implementations welcome as well :)

[Dovecot] File isn't in mbox format - Couldn't open INBOX
by Rich West 24 Apr '05

24 Apr '05

While I saw another thread on the list similar to the issue I was experiencing (http://dovecot.org/pipermail/dovecot/2005-February/006168.html) I was wondering if there was a way around this problem (the thread simply suggested upgrading, but are the later version (specifically the 1.0-test releases) ready for prime time?)... We're periodically having this with some users (not sure what client they are using, but I am pretty sure it is MS Outlook) where the inbox is in near perfect shape except for some extra characters at the beginning of the file. POP or IMAP delivery fails with an error stating "File isn't in mbox format - Couldn't open INBOX". It looks like those characters are of a previous message that was not completely removed from the file, and those characters seem to throw everything out of wack.. It's easily correctable by removing the bogus characters from the beginning of the file, but that gets annoying quickly.. -Rich

[Dovecot] about filtering and dovecot
by Bram Mertens 24 Apr '05

24 Apr '05

Hi I would like to set up a local mailserver but I'm getting lost with all the available options. As I have already decided to use dovecot I hope someone here will be able to point me to the right docs/HOWTO's/... Here's my wish-list: 1) download mail from my ISP's POP3-server 2) scan with spamassassin 3) scan with ClamAV 4) filter messages (mailing lists/sender/...) 5) store messages in dovecot 6) be able to read messages on my desktop (where all of the above will be running) and on my laptop 7) be able to send messages (currently using evolution) from both my desktop and laptop so sent messages are stored in dovecot (the idea is to be able to see all sent messages on both PC's) I have already created a test-account om my ISP's POP3-server, installed and configured fetchmail and dovecot. Exim has been installed as well but I haven't touched it's configuration yet. Running fetchmail manually collects the mail and stores it in /var/mail/m8ram where dovecot finds it. So I would like to know (how to find out) how I can achieve 2), 3), 4) and 7). I have looked around and have discovered that there are many programs that can do some or all of this. But I haven't been able to figure out how to get them to work with dovecot. e.g. I don't understand what I would have to change to dovecot's config if exim or procmail or whatever moves certain messages to different folders (or even where these folders would be created). Perhaps I'm missing a HOWTO that explains all this, if so please let me know.

RE: [Dovecot] IMAP EXPUNGE disconnect/box hang - Fedora Core 2, Squirrelmail and Evolution
by Schettino, John Charles 24 Apr '05

24 Apr '05

Well, I just built and installed the 1.0 stable w/o tags version from source, and so far, it's not hanging/crashing the system - if this is the fix, I'm all over it :D Context: this is my problem: Correction: I'm running yum.log:03/07/05 05:48:28 Updated: dovecot 0.99.14-1.1.fc2.rf.i386 - Sorry about that. I'm a bit befuddled by this behavior. I've been using dovecot for close to a year, and recently the Fedora Core 2 Update: dovecot-0.99.13-4.FC2 build came in via yum. Since then I occasionally get this EXPUNGE disconnect error. When the error hits, the box does not crash but I can no longer log in*, nor start any new processes. I happen to have gkrellm running and I see a slow but steady climb in the # of processess. The only way to recover the box is to do a hard reset, as I cannot log in, nor su - to do a shutdown. In one case I happened to have a root shell open, and I still could not do a shutdown. Any ideas as to what I should do with this? As long as I don't expung everything is fine, but when I do expunge (move something or a filter runs in squirrelmail, or Action/Expunge in Evolution) sometimes it works fine, sometimes I get this error and a weird zombie state. It was all rock solid before this new version. Suggestions welcome - I don't seem to be getting any logging when it goes bad, perhaps I can up the log level? I'm more then happy to build the current dovecot from source, and if I should post this to some Fedora list, point me at it :D

[Dovecot] Dovecot LDA with sieve scripting
by Timo Sirainen 23 Apr '05

23 Apr '05

I also placed dovecot-lda-0.1.tar.gz in http://dovecot.org/test/. It's also in dovecot-lda module in CVS. It's based on the same deliver binary that exists in Dovecot's sources, but I've also plugged in CMU Sieve (mostly because it was the easiest one to plug in). The code could be much prettier, but it works anyway :) I think at some point I'm going to try to make the Sieve stuff a plugin on top of the normal delivery binary. (Dovecot in general should have some pretty plugin architecture, so you could just unpack them in some directory then do ./configure --with-builtin-plugins=quota-maildir,lda-sieve --with-external-plugins=sql,ldap,quota-sql) configure needs --with-dovecot=../dovecot-1.0-test68 option. So, usage goes like I mentioned in my previous mail (uhm. should put it into README): http://dovecot.org/list/dovecot/2005-March/006512.html Sieve script is assumed to be in ~/.dovecot.sieve file. It's automatically compiled to ~/.dovecot.sievec whenever timestamp changes. If it doesn't exist, mail is stored normally into INBOX.

[Dovecot] password_verify in test67 with ldap
by Thomas Hummel 23 Apr '05

23 Apr '05

Hello Timo, your patch introducing pass_attr_names and user_attr_names fixed the problem of the 'shared' attr_names member of [passdb|userdb]_ldap_conn as I answered in the relative thread. Now I think there is a problem while comparing user-provided and ldap-provided passwords causing a false 'password mismatch' situation, while using PLAIN mechanism with LDAP authentication. As a matter of fact, the user provided by the user, as read in the 'mech_plain_auth_continue' function is passed as an argument in the 'auth_request_verify_plain' function which, in turns pass it to the function pointed to by 'passdb->verify_plain' (that is 'ldap_verify_plain') which doesn't use it [instead maybe of setting the 'passdb_ldap_request' 'password' field with it ?]. So once back from the LDAP request, when in 'handle_request' we call 'password_verify', the password we try to match against the one read in the LDAP db is null. Did I get it right ?

Hello, I'm a bit afraid of users, the might slow down the server because of search requests to the imap-server on very large mailboxes. Even with a performant index, this could cause a lot of cpu and i/o-load. Is it possible to include the login-name in the imap process, so that a "ps ax" doesn't just give "imap", but e.g. "imap test(a)example.com"? Maybe it's of general interest to see in the title at which stage an imap-process is working. Regards Marten

[Dovecot] message status changed from new to old on read
by Andrew Pimlott 21 Apr '05

21 Apr '05

Hi. I'm new to IMAP, but just tried uw-imapd and then dovecot in conjuction with offlineimap. I'm using Debian package version 0.99.14-1 and have my mail in mbox format. One of the first things that annoys me about both programs is that as soon as you read a mailbox over imap, the imapd changes all "new" messages to "old". It seems to have the assumption that the IMAP client is "reading" the messages, but particularly in the case of offlineimap, this assumption is not justified: I might not read the message on the client on which I've just synced, I might read it on the server or another client. So I would like dovecot to leave the mailbox alone, and leave it up to the client to write any changes to message status. Is there any option to dovecot that would accomplish this? While experimenting, I noticed that dovecot sometimes doesn't notice changes to the status made directly on the server. For example, if I create new mbox mailbox with one message (initially "new"), and access it with imap (using mutt in this example), it shows up "new" in the client. When I next access it with imap, it shows up "old", because dovecot modified the status as described above. If I then run mutt directly on the mailbox and change the status back to "new", then access it with imap, it still shows up "old". If I then remove the .imap directory containing the caches, it is back to "new". I assume that dovecot is supposed to pick up changes made directly on the server, right? Thanks for your help, Andrew

[Dovecot] minimial maildir++ quota for dovecot-0.99
by David Harris 21 Apr '05

21 Apr '05

Hello, I'm using dovecot-0.99.14, and I wonder if anyone has created patch for *minimal* Maildir++ support. By minimal Maildir++ support, I mean the following: (1) New messages created by dovecot will include the ,S=nnnnn string in the unique identifier so that Maildir++ clients don't have to stat the file to know the size. (2) Dovecot will append to the maildirsize file when a message is deleted or added. If maildirsize gets larger than the 5120 limit, then just delete it and let someone else recalculate the quota. My goal isn't full Maildir++ support in dovecot, but just to make it play nicely with my Maildir++ aware delivery agent. (If someone has full Maildir++ support, I'd be glad for that too!) If what I describe above doesn't exist, I am interested in paying someone to make this quick patch. E-mail me off list if you are interested. Thanks, David

[Dovecot] dovecot ssl problem
by Alexander Heuer 20 Apr '05

20 Apr '05

Hi there, I am having a weird problem with dovecot and ssl. If I am accessing the dovecot imap server with for example sylpheed-claws or evolution, everything works fine. If it is accessed via windows either by outlook or thunderbird, we get occassional timeouts. It's working fine for a few hours, then for 5 to 20 minutes, every attempt to connect from the outside results in "Connection to server timed out". Added to that, the problem only arises, if a direct SSL connection to Port 993 is used. Using Sylpheed with STARTTLS to Port 143 from the outside works fine as well. It's not a firewall Problem, since port 993 and 143 are open, the config files have been checked over and over for 2 weeks and are good as well. Dovecot log says: imap-login: Apr 20 13:26:05 Warning: SSL_read() syscall failed: Connection timed out [83.104.224.142] Doing uber verbose output doesn't bring up any extended information, syslog stays clean as well. The Problem is not directly reproducable by a certain action, it just arises from time to time. There can be 3 working days without problems, or 6 timeouts > 20 minutes within one day. System is Debian Sarge unstable with a custom 2.6.10 Kernel. During the timeouts, mail is still received and put into the users mailboxes by exim, it's just that you cannot access the imap server for approx 20 minutes. Dovecot version is 0.99.14 Regards Alexander Heuer

[Dovecot] dovecot-sasl license
by Marcus Rueckert 19 Apr '05

19 Apr '05

hi, i talked to timo about re-licensing the sasl part of dovecot under a more liberal license (bsd/lgpl e.g.). it would allow the integration of it in bsd base systems. another reason i would be interested is adding sasl support to svnserve [1]. so here is my question: what is your oppinion about this issue? any objections from contributors? darix [1] http://subversion.tigris.org/ -- irssi - the client of the smart and beautiful people http://www.irssi.de/

[Dovecot] attr_names in test67

Hello, I'm wondering if the following situation is valid (though I think it isn't since I still cannot authenticate with ldap pass/userdb on test67 running on FreeBSD-5.3).

[Dovecot] SORT using cached filesystem modtimes
by Emmett Lazich 18 Apr '05

18 Apr '05

Timo or anyone, This may be a bug or maybe a design decision. Either way I am curious to hear comments. Why do the dovecot-0.99.14 server's .imap.index files contain a cached copy of each message's date and time as supplied by the filesystem, as opposed to the date and time found in each message header? When testing various imap clients (eg. tbird-1.0.2, evolution-2.0, outlook2003, squirrelmail-1.4.4) I was intrigued by the behaviour of message date sorting. I toggled on/off the use of server side SORTing in some imap clients, then started forcing rebuilds of .map.index files, and eventually came to the above conclusion. For normal dovecot server side processing, this condition (if I am correct) may not be a problem, but if someone was to deposit a bunch of maildir files firstly into an imap account (bypassing dovecot), and if this person (eg. me) did not preserve the filesystem/inode file attributes. Then dovecot appears to cache the "wrong" data. What happens then is that some imap clients can display wrong date+times in the message lists, and some imap clients find that server side SORTing does not work. Keen to hear thoughts/opinions. -Emmett

[Dovecot] Dovecot causing hanging on random folders...
by Rick Flower 17 Apr '05

17 Apr '05

I've been using the 1.0 test series (currently 1.0test 67 and before that 1.0-test59) and both exhibited this issue.. I use Thunderbird and will open one or two of my nested Maildir folders via imap and find that it goes out there trying to open the folder (according to the messages that Thunderbird claims) and it never comes back.. I've attached to the various dovecot processes to see what their doing and they appear to be waiting for things to do -- e.g. not working on anything in particular.. The only way to fix this is to quit Thunderbird and restart it.. I see this about 2-3 times a day.. I'd love to track it down.. I've seen this on Fedora Core 1 (i386 server) and also on a PPC Linux system running an older kernel (on a Buffalo Linkstation if you know what that is).. Below is the current set of dovecot processes running on my FC1 box : [rickf@srv1 dovecot-1.0-test67]# ps aux | grep dove root 748 0.0 0.0 3380 720 ?

From the WIki features page, ( http://wiki.dovecot.org/moin.cgi/CoreFeatures ) it's not clear to me if the dovecot-stable release supports multiple authentications mechanisms (like in 1.0-testxx). I need both virtual domains and system users. Can I use the stable release for this? Thanks, --Micha

[Dovecot] Failed to create storage with data:
by Matthieu Imbert 17 Apr '05

17 Apr '05

Hi, i'm using dovecot-1.0-stable. All my mail accounts are virtual accounts that come from pam with the following configuration in auth_default: passdb = pam userdb = static uid=5000 gid=5000 home=/var/mail/vhost/example.com/%n mail=/var/mail/vhost/example.com/%n for a user foo, if the directory /var/mail/vhost/example.com/foo already exists, then all is ok, but if the directory doesn't exists, it seems dovecot is unable to create it "on the fly". I get the following error message: Failed to create storage with data: /var/mail/vhost/example.com/foo i'm quite sure it is not a permission related problem (i made /var/mail/vhost/example.com world writable to be sure). I'm currently trying to understand the maildir code... But could someone tell me if the maildir directory should exist for dovecot to work ? In the case that the answer is yes, i would say in advance that it's a problem for sites hosting a lot of virtual users, since it means that these users must receive at least one mail for their mail account to work correctly (i use postfix as MTA, and if the user's maildir doesn't exist, postfix takes care of creating it). I'm not very fond of solutions with scripts taking care of creating users. Thanks in advance for your answers :) -- \|||/ (o o) Matthieu Imbert ooO-(_)-Ooo------------------------------------------ équipe administration réseau et systèmes Ecole normale superieure lettres et sciences humaines 15, Parvis René Descartes BP 7000 69342 LYON cedex 07 tél 0437376127, secrétariat 0437376122 fax 0437376123 contact équipe réseau et systèmes <reseau(a)ens-lsh.fr> contact personnel <matthieu.imbert(a)ens-lsh.fr> -----------------------------------------------------

[Dovecot] dovecot and evolution

I am using dovecot 0.99.13 and Evolution 2.0.2 on Fedora Core 3. Recently, Ximian stopped being able to access my local INBOX via IMAP, failing with the following error: Error while Opening folder imap://malsyned@localhost/INBOX. Incomplete server response: no information provided for message 1. I got a transcript of the conversation between Evolution and dovecot.

The headers it gives for message #2 are the same as the first message in my mailspool, and the headers for message #3 are those of the second message in my mailspool. It goes on from there. This doesn't happen to other folders I try to access via IMAP, only my INBOX. Since this only seems to affect Evolution and not pine, I don't know whether this is technically a bug in dovecot or Evolution. I guess that's up to the RFC, which I haven't read all the way through. Anybody got an idea about how to fix this or what's causing it? (Please CC me directly on any replies, I'm not subscribed to this mailing list) Thanks, --Dennis Lambe, <malsyned(a)gmail.com> P.S. Is there a way to get a session transcript out of dovecot? It would save me a fair bit of perl hackery.

[Dovecot] Upcoming configuration file changes
by Timo Sirainen 17 Apr '05

17 Apr '05

For those who might be interested. Comments welcome. A few weeks ago I had started redesigning how Dovecot handles configuration files. I wrote a new parser and converted dovecot-auth to use the new way. Today I finally managed to convert imap process as well, which wasn't that easy because I didn't want mbox/maildir-specific settings to be hardcoded in any common code. So, the changes will be: - Dovecot master process will need a new completely different configuration file which tells what processes to run and their uids/chroots/memory limits. Very much like Postfix's master.cf. I'm not sure about its format yet (suggestions welcome), but maybe something like it's already: process imap-login { executable = /usr/lib/dovecot/imap-login chroot = /var/run/dovecot/login uid = dovecot vsz_limit = 32M } ... Hopefully after these changes the master process will become very small and simple. - One of the processes will be a configuration process, which is the one that reads and parses the configuration for non-master processes. The default configuration file format will be pretty similar to what we have now, but it can of course be replaced with SQL backends and whatever. Config process will listen in some unix socket waiting for requests from other processes, which connect to it just after they start up and maybe also sometimes later (eg. to get user/IP-specific settings when a new client connects). - The data that config process sends and what other processes parse is based on simple key=value pairs, so it's possible to still store and parse them from environment if needed. Also it makes it possible to override settings from command line (eg. imap -o mail_debug=yes) or give user-specific settings in userdb. Here's an example: # config process reads something like: mmap_disable = yes namespace foo { type = private separator = / mbox { dir = ~/mail mbox_read_locks = dotlock } } # sends out: mmap_disable = yes namespaces = foo namespaces_foo_type = private namespaces_foo_separator = / namespaces_foo_mbox = 1 namespaces_foo_mbox_1_dir = ~/mail namespaces_foo_mbox_1_mbox_read_locks = dotlock - Config process should verify that all given settings are valid so that typos are noticed. This may not be that easy because the setting definitions are distributed all around the source code. I think there needs to be at least a (Perl) script that finds out all the setting definitions and writes them to some all-settings.c for config process so it knows them. Settings for plugins are more difficult though.. Should they somehow be marked in config file that they're plugins (plugin foo { .. })? Or maybe config process could dynamically load all the plugins itself and request their setting definitions?

[Dovecot] Logwatch
by Rich West 16 Apr '05

16 Apr '05

Having FC3 systems and utilizing Dovecot, I have come to rely on some of the information I get from the daily logwatch run. Logwatch, by default, doesn't properly recognize dovecot's information in the messages file, but it is easy to tweak. The patch below will give you some statistics regarding POP3 and IMAP usage. I believe I grabbed all of the differences in the unified diff below.

[Dovecot] comparision with other imap servers and folder sharing
by Emmett Lazich 15 Apr '05

15 Apr '05

Some praise: Timo, I must say I am super impressed with this product. I do free support a few good friends with small businesses running Linux servers (a mix of RH9, Suse9.2 and gentoo) that I dropped as email and samba servers. I found UW-IMAP to be terrible in every way except that using mbox is sometimes nice for old s/w tools. No need for details re UW-IMAP problems. In early 2004 I found courier-imap to be vastly better behaved than UW-IMAP and also much faster once large folders were open. DJB's Maildirs seemed cool, and postfix likes them too, and mb2md-3.20.pl worked great . So everything seemed good and certainly was better. But courier cannot cope with large imap accounts (eg. millions of messages and a few GBytes) where courier-imap grinds to a halt on the initial folder scanning. Cyrus just looks like a big evil beast that needs too much time to learn. Four days ago, this lead me to dovecot. The performance, reliability, configurability of dovecot is amazing. Timo, I think you could give yourself more credit on something important when selling Dovecot. You write that Dovecot "does not support shared folders". This might turn away some people considering Dovecot. People whom like me do not have/want a good understanding of the imap protocol. I believe you mean that Dovecot does not support shared folders in the technical imap sense of shared namespaces between separate imap accounts. Since Dovecot works beautifully when sharing folders via logging in with the same username more than once. Plus your documentation and config notes imply that this is no problem. IDLE and fcntl locking works great for me. Thank you and good luck! -Emmett

How can I configure the dovecot for working with maildir's through NFS? If I add option "index_mmap_invalidate = yes" (as in doc/nfs.t) then in log I have this message: "Error: Error in configuration file /etc/dovecot.conf line 296: Unknown setting: index_mmap_invalidate" If I try to get the mail without option "index_mmap_invalidate" then I have in log this message: "Error: POP3(butyrev.lk): mail_index_lock_fd() failed with file /var/mail/sam-butyrev.lk/dovecot.index.log: No locks available dovecot: Error: POP3(butyrev.lk): mail_index_wait_lock_fd() failed with file /var/mail/sam-butyrev.lk/dovecot.index.log: No locks available dovecot: Error: POP3(butyrev.lk): Couldn't open INBOX: Internal error occured.

[Dovecot] test67 ldap_connection

As 'passdb_ldap_conn' and 'userdb_ldap_conn' are of the 'ldap_connection' type and since the 'db_ldap_init' function returns the existing ldap connection if it exists, the 'passdb_ldap_preinit' and 'usedb_ldap_preinit' will call the 'db_ldap_set_attrs' function on _the same_ 'ldap_connection' object. - So when the 'db_ldap_search' function is called from the 'passdb-ldap.c:ldap_lookup_pass function, the 5th argument (passdb_ldap_conn->attr_names) will point to the 'user_attrs' instead of the 'pass_attrs', since userdb_preinit will have already been called. - I've also noticed the use of the 'attr_map' hash to store the attribute/value pairs, but since it doesn't seems to be used when calling 'ldap_lookup_pass', I guess the problem is somewhere else. Can someone give me a clue ? Has someone successfully set up dovecot-1.0-test67 on a similar configuration ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Syslog, Dovecot, and LogWatch
by Rich West 12 Apr '05

12 Apr '05

At what level does Dovecot log to syslog? UW-IMAP uses local6.debug to log to syslog, but it doesn't seem that dovecot does the same.. (the file I defined for UW-IMAP's output hasn't received anything since I moved over to Dovecot? Also, has anyone managed to get LogWatch and Dovecot to play nicely together? I noticed that LogWatch no longer gives any statistics on the imap usage since I shut down UW and went full blast with Dovecot.. -Rich

[Dovecot] Index(?) problem under OpenBSD
by Gaby vanhegan 12 Apr '05

12 Apr '05

Hi, My apologies if this has been mentioned before, I haven't pulled up a google search yet. I run Dovecot from the package under OpenBSD 3.6 (dovecot-0.99.10.8). The problem I have is that occasionally dovecot corrupts an index file (I think), which causes the process to gradually creep up in usage, until it hits 99%, where it stays, without quitting. If I then fire up my mail client later on, it does the same thing. Doing this two or three times results in 3 processes, all at 33%, and a load of 100 on the server. The problem is resolved by deleting all the index files in my Maildir. If this doesn't solve the problem, then duplicating my Maildir and using the new copy, after deleting all the index files, fixes the problem. But these only work for a while, and the problem rears it's head with other users as well, so I need a fix. Has anybody else suffered this problem? Is there a fix in a more recent version? Is it OpenBSD specific? What can I do to help diagnose the problem? Should I turn of indexes? Upgrade to the latest version? Some example errors from my logfile: imap(gaby): Apr 11 15:32:37 Error: Corrupted index file /home/gaby/Maildir/.INBOX/.imap.index: Wrong messages_count in header (261 != 382) imap(gaby): Apr 11 15:32:37 Error: Corrupted index data file /home/gaby/Maildir/.INBOX/.imap.index.data: used_file_size larger than real file size (142368 vs 10264) imap(gaby): Apr 11 15:32:44 Error: Corrupted index file (in-memory index for /home/gaby/Maildir): UIDVALIDITY changed in uidlist imap(gaby): Apr 11 15:36:12 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Work.LTSN/.imap.index imap(gaby): Apr 11 16:21:27 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Archive.Trash-20050308/.ima imap(gaby): Apr 11 16:25:02 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Archive.Trash-20050407/.ima Gaby -- Uganda Maximum - Enemy of the English Thrust gaby(a)vanhegan.net http://weblog.vanhegan.net

[Dovecot] Namespace prefix not ending with separator
by Chris Wakelin 11 Apr '05

11 Apr '05

I'm still battling my way through using hidden namespaces to hide the change from UW-IMAP to Dovecot 1.0-stable from my users. The latest problem is that some (probably many) users have their IMAP folder prefix set to "~/mail" rather than "~/mail/". I have hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/". LIST "~/mail" "*" returns nothing, so I've tried adding another namespace for "~/mail". Now LIST "~/mail" "*" returns * LIST (\NoInferiors \UnMarked) "/" "~/mailtest1/test1-2" * LIST (\NoInferiors \UnMarked) "/" "~/mailtest2" * LIST (\NoInferiors \UnMarked) "/" "~/mailtest3" whereas UW-IMAP returns * LIST (\NoInferiors \UnMarked) "/" ~/mail/test1/test1-2 * LIST (\NoInferiors \UnMarked) "/" ~/mail/test2 * LIST (\NoInferiors \UnMarked) "/" ~/mail/test3 I wonder whether LIST should insert an extra namespace separator in such cases? Having said that, it seems to work, except it may cause problems with folder subscriptions, which I've had to hack in order for them to be compatible with UW-IMAP (i.e. to store them as "~/mail/test1" etc.) 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] imap segfault in mail-index-sync.c
by Todd Burroughs 10 Apr '05

10 Apr '05

Our support team seems to have caused another crash. They treat this mailbox like a shared one, so there may be a few people accessing it at once. They are mostly using dovecot, but some could be using uw-imap. These are the only two ways that this box is accessed. I know that this doesn't really work with mbox, but it doesn't appear to corrupt the mailbox. It seems to be a good stress test... In this case, it looks like several of them are logged in at once. Here's the log entry and backtrace of the imap process which segfaulted. I'll put a section of logs covering this time at the end, in case it helps.

[Dovecot] Authentication and the wrong mailbox?
by Rich West 10 Apr '05

10 Apr '05

I just migrated from UW-imap to dovecot last night. After some tweaking of the dovecot.conf file, disabling xinetd's entries, firing up the dovecot daemon, and copying the .mailboxlist to .subscriptions for all users, things looked to be going just fine! I received a call this morning from a user stating that they had all of *my* emails in *their* inbox! They don't know when it happened as their machine POP's email off every 5-10 minutes or so, but we were able to isolate it to a 8hr period last night. Further investigation showed that at some time through the evening, dovecot freaked out during the authentication phase and for some bizzare reason, when the user connected via POP3, they were able to download all of my inbox! Additionally, by the time I was looking in to it, NO users could authenticate via dovecot, and, hence, no one had access to email. Restarting dovecot resolved the issue, but I have my doubts about it being truly resolved. I'm going to run some tests (what little I can think of), but this is the first time I have ever experienced a situation such as this. One thing for UW is that this situation never happened, and I've only had dovecot running for about 13hrs. Any ideas as to how or why this may have happened, and how it can be prevented, would be wonderful. -Rich -- Richard West $14.95 Registrations mailto:rwest@wesmo.com Wesmo Computer Services .com .net .org .tv .cc http://www.wesmo.com Full Domain & Web Hosting .BIZ .INFO & MORE!!

[Dovecot] Outlook express confusion
by Andrew Hutchings 08 Apr '05

08 Apr '05

Hi, This may be a problem with my config file but I am finding that customers (and more importantly my boss) that are using outlook express when using test66/67 (upgraded from test60 + from address patch) are having message reappear after being fully deleted (not just marked) but are unreadable, sometimes blank headers appear too but again no message. Since it is affecting my boss he has told me to go back to test60 or lower, and won't let me find the problem.

[Dovecot] maildir quota management
by Wayne Lovely 08 Apr '05

08 Apr '05

Hi everyone, my name is Wayne Lovely and this is my first post. My company has a need for dovecot to decrement the portion of quota used. The used portion and hard limit will be stored in a central database. Initially I'll just hack in what we need as a proof of concept, but I would like to get some input into what people would really like, such that I can make a good contribution. regards, Wayne Lovely

[Dovecot] 1.0-test67
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ Hopefully better release than last one. Fixes several problems test66 had and also some older problems reported in this list. It also contains a pretty large mbox code cleanup, fixing several problems (especially related to X-IMAP/X-IMAPbase headers) and making it a bit faster. Maybe I'll backport it to 1.0-stable too when it looks like it's stable.. BTW. mbox code is slower than necessary when updating message flags and mbox_lazy_writes=yes, because it reads message headers for each message whose flag is to be changed (in index). Should fix that one soon too..

Re: [Dovecot] Delimiter of mailbox changes in response to STATUS command...
by Lawrence Katz 08 Apr '05

08 Apr '05

Hi Chris - Thank you for the reply. > I can't reproduce this in our setup in either 1.0-stable or > 1.0-test66. What's your namespace definition and MAIL= environment? > What does > > 1 LIST "Misc/" "*" > > give you? The LIST command returns what I expect to see (for readability): 2 list "Misc/" "*" * LIST (\HasNoChildren) "/" "Misc/Spam" > Can you 1 SELECT "Misc/Spam" OK? I can select that mailbox as well as others without a problem. Here's what NAMESPACE returns: 3 NAMESPACE * NAMESPACE (("" "/")) NIL NIL My namespace definition in dovecot.conf is as follows: namespace private { separator = / # prefix = # location = inbox = yes # hidden = yes } I didn't have default_mail_env set to anything, but I just tried the following without a change in the STATUS command's behavior: default_mail_env = maildir:/home/%u/Maildir Is there any other information that might help? Thanks, Lawrence

[Dovecot] Linux, Maildir over NFS, Locking problems
by Terrence Martin 08 Apr '05

08 Apr '05

Hi, I am having problems with file locks with my NFS mounted Maildir setup. NFS Client/IMAP Server is RHEL3 clone whitebox and NFS server is a Fedora Core 2 system. Both are running lockd as far as I can tell. dovecot is installed with Dag's latest dovecot RPMs for RHEL3. Time is synced between the two systems. Here is the pertinent log file entry dovecot: Dovecot starting up Apr 7 11:17:42 sentry imap(tmartin): /home/tmartin/Maildir/.subscriptions failed with subscription file file_wait_lock(): No locks available Now what I can find in nfs.txt is that I need to use fnctl is this ".customflags and .subscriptions files require fcntl() locking currently. Many NFS servers don't support it, at least without a separate lockd daemon. These will be fixed later to be NFS-safe by default." My question is am I using fcntl? The only reference I can find in the config refers to mbox formats, but I am using maildir. Setting the one reference to fcntl does not seem to have any effect. Is there a configuration setting to tell the server to use fcntl locks or a way to tell if it is trying to use fcntl locks? Thanks for any tips, Terrence

[Dovecot] MySQL-Auth Problem

Hi, i would use Dovecot-test66 with MySQL-Auth for virtual users.

[Dovecot] 1.0-test66
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ I've still lots of mails in my INBOX and in this list that I should be looking into.. But here's a release that fixes at least some things. Maybe I'll make another one tomorrow.. Most importantly keyword code was changed a lot. It's now faster and less buggy. The keywords are also finally written into mbox, and keyword changes in the mbox are picked up. So upgrading from Dovecot 0.99.x or UW-IMAP (or reverting back to them) doesn't anymore lose the keywords. Maildir still needs 0.99.x-compatible customflags-file and storing the keywords as a..z flags in maildir filename. Hopefully I'll get that done soon, and then we should be nearing 1.0-alpha1 release :) The new keyword code hasn't been tested much, so this might be less stable than earlier versions. - Renamed oe6-fetch-no-newmail workaround to delay-newmail and changed it to work more like the name says: only newmail notifications are skipped and not only for FETCH command. - LDAP crashfixes - Changed FETCH to return smaller items first. Should fix all kmail and Thunderbird problems. Removed tb-negative-fetch workaround as it shouldn't be needed anymore. - Cache file was breaking constantly with test65 - Blocking passdb fixes and proper RPA realm support patches from Andrey - in-memory indexes should be working again if someone wants to use them for some reason (:INDEX=MEMORY) - gzipped mbox plugin http://dovecot.org/patches/1.0/zlib-plugin.tar.gz - SORT crashfix - Some mbox rewriting fixes (should fix some asserts) - etc.

[Dovecot] Archiving Dovecot format maildir
by Leslie Viljoen 08 Apr '05

08 Apr '05

Hi! It seems that the Maildir format used by Dovecot is a standard, right? Has anyone written something to archive mail in Dovecot format maildirs? I have a script that seems to be for Cyrus IMAP but it doesn't seem to work. I'll write a Perl program if there is nothing available but I am concerned about dovecot's index files - do I need to do anything to get dovecot to rebuild them? Leslie Viljoen

[Dovecot] headers don't match message
by Kevin 08 Apr '05

08 Apr '05

the other day i moved all mail functions to a different machine. i copied over my existing maildir's and installed dovecot-stable-20050405. once i had everything moved and dovecot running i checked my mail via imap. all the messages appeared however when i try to read a message the message body doesn't match the header info that's showed in the message list. is this an index problem? or did i corrupt my maildir when i moved it over to another host?

[Dovecot] public or shared folders
by Richard Stegman 08 Apr '05

08 Apr '05

Hello I would like to setup a public namespace with folders under it that are accessiable by certain users. Something like this: Projects---- | |-----03060 | |-----04579 Users should be able to move emails from their inbox to the shared folders, and all user can see the moved email. Here is what I have done so far: 1. I installed dovecot-1.0-0 4 stable20050221.rhf3.at.i386.rpm to a Fedora core 3 machine with Postfix and procmail. 2. Tested mail server - both pop and imap work. 3. Modified dovecot conf. file with the following entry: namespace private { separator = / prefix = inbox = yes hidden = no } namespace public { separator = . prefix = Projects. location = maildir:/var/mail/Projects inbox = no hidden = no } 4. Restart dovecot. Test - imap and pop work. 5. Create group imapu. Add email users to group imapu 6. Create (as root) /var/mail/Projects. Change group to imapu. Change mode 770 7. Touch file dovecot-shared to /var/mail/Projects. Change group to imapu. Change mode 770 8. Make directory /var/mail/Projects/.03060. Change group to imapu. Change mode 770 9. Touch file dovecot-shared to /var/mail/Projects/.03060. Change group to imapu. Change mode to 770 10. Restart dovecot. I start up thunderbird and the Project namespace shows up. I then subscribe to 03060 and get this error: The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' <10240.-1357>'. I click ok and I can move email from the inbox to 03060. The mail shows up in 03060. No other user can then subscribe to 03060. What am I doing wrong? Thanks Rick

[Dovecot] pam problems
by Matthieu Imbert 07 Apr '05

07 Apr '05

Hi, i'm quite new to dovecot. i built it from the stable-1.0 sources. i have the following error messages in syslog when trying to launch dovecot: dovecot: Dovecot v1.0-stable starting up dovecot: auth(default): Unknown passdb type 'pam' dovecot: Auth process died too early - shutting down dovecot: child 373 (auth) returned error 89 i googled a bit, and found some posts on this mailing list describing the same problem, and the answer is that pam support is not compiled in. So i tried to ensure pam support would be compiled: i made sure that i have the proper libs. I work on debian so i did: apt-get install libpam-runtime libpam-modules apt-show-version tells me the version numbers installed: ... libpam-modules/testing uptodate 0.76-22 libpam0g/testing uptodate 0.76-22 libpam-runtime/testing uptodate 0.76-22 libpam-ldap/stable uptodate 140-1 ... my configure line is as follows: ./configure --sysconfdir=/etc --localstatedir=/var --with-ssl=openssl --with-pam when running configure, the only line related to pam is the following: checking for pam_start in -lpam... no and at the end of the configure script i get the following summary: Building with user database modules : static passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword (modules) So it seems that pam support is not built in. What is the lib i am missing ? Any help appreciated, thanks -- \|||/ (o o) Matthieu Imbert ooO-(_)-Ooo------------------------------------------ équipe administration réseau et systèmes Ecole normale superieure lettres et sciences humaines 15, Parvis René Descartes BP 7000 69342 LYON cedex 07 tél 0437376127, secrétariat 0437376122 fax 0437376123 contact équipe réseau et systèmes <reseau(a)ens-lsh.fr> contact personnel <matthieu.imbert(a)ens-lsh.fr> -----------------------------------------------------

I followed Geralds' instructions and dovecot returns "0 0" to stat cmd and "0 messages:" to list. So it thinks there are zero when there are over 40 in "%h/.maildir". I had not changed my config file before reboot so how can this happen? It worked prior to reboot and not after. I get no maillog errors, what next? Thx.

[Dovecot] Delimiter of mailbox changes in response to STATUS command...
by Lawrence Katz 06 Apr '05

06 Apr '05

Hi - I've been using Hastymail with my Dovecot server for awhile now. However, I have noticed that at some point Hastymail stopped showing the number of unseen messages in its folder drop down list, it just shows 0 for the folders that I have it checking for unseen messages. I'm not sure when it broke, but I think it's when I went to one of the testing builds several months ago. I just upgraded to Hastymail 1.3 and Dovecot testing66 today just to see if the issue would go away and it hasn't. So I did some digging and I think I found the cause of the issue... If I send a STATUS command, like the one shown below, Dovecot changes the mailbox delimiter in the result from a "/" to a "."... 2 STATUS "Misc/Spam" (UNSEEN) * STATUS "Misc.Spam" (UNSEEN 3) 2 OK Status completed. I was able to work around this in Hastymail by substituting a "/" for a "." when the result comes back, but it's not that elegant. Any thoughts on why this might be happening in Dovecot? Is it a configuration issue on my part, or a bug? The private namespace in my dovecot.conf has the following: separator = / Thanks, Lawrence

[Dovecot] Dovecot 1.0 POP3 login but no mail
by David Wynter 06 Apr '05

06 Apr '05

Dovecot is installed on the hosted FC1 server I have, it was working fine until yesterday when they had to bounce the server. I can login fine from Outlook or connect telnet <hostname> 110. But even though I can see sendmail has received mail into my %h/.maildir (via webmail's user mail facility) when I log into dovecot via Outlook it does not retrieve any of it. I tried from W2K "telnet <hostname> 110", it connects "+OK dovecot ready.", then I typed "LOGIN <username> <password>" and i get "-ERR Unknown command.". However with Outlook it logs in fine I see in maillog the result, no other errors in maillog. Cannot see what is wrong. Here are the important bits of my dovecot.conf, everything else is std. i.e. commented out protocols = pop3 login = imap login = pop3 default_mail_env = maildir:%h/.maildir client_workarounds = outlook-idle mbox_locks = fcntl auth = default auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes Ideas on where to look next?

[Dovecot] FETCH order fix backport to stable from test66
by Chris Wakelin 05 Apr '05

05 Apr '05

I've had a go at back-porting Timo's recent fixes to the IMAP fetch command from 1.0-test66 to 1.0-stable. This seems to fix the problem with kmail, and Thunderbird seems to work fine without its RFC822.SIZE fix. It's a bit big for the body of this message, so it's attached.

[Dovecot] ldap auth with test66
by Thomas Hummel 04 Apr '05

04 Apr '05

Hello, The installation of 1.0-test66 (still on FreeBSD 5.3-RELEASE-p1 with openldap-2.1.27) solved the SIGSEV problem I posted here on March 30 but I still cannot authenticate correctly with ldap. logs report "ldap(dovetest,127.0.0.1): No password in reply" and my client gets a "NO Temporary authentication failure." Obviously the attr_names array of the passdb_ldap_connection struct is valid until the preinit function but has been corrupted when we're at the passdb_init function. For instance, here's what I get in the log file for the 'fields' value : --- dovecot: Apr 04 11:43:19 Info: Dovecot v1.0-test66 starting up dovecot: Apr 04 11:44:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AGRvdmV0ZXN0AHBhc3M = dovecot: Apr 04 11:44:58 Info: auth(default): ldap(dovetest,127.0.0.1): base=ou= personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(u id=dovetest)) fields=0^S^<^S^d^S^°^S^ð^S^^T^T^Ð^T^Ø^T^^C -- Beside, I could notice, by adding some logging info, that the attr_names seem to hold the USER attrs instead of the PASS attrs. I'm trying now to investigate further through gdb (I added a sleep in the main of dovecot-auth to be able to attach the running process in gdb) but without success for now. Do you have any clue of where I should look ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Nested folders
by Michael Irons 03 Apr '05

03 Apr '05

I would like to have nested folders that users could create from their MUA. The problem is that I cannot create sub folders either through the MUA or by hand on the server side. I can make folders that are not the subfolder of anything. I have an Inbox, Mailing Lists, Spam, Trash, etc. But I cannot create subfolders of these. For example, I would like a subfolder under Mailing Lists for each Mailing list that I have subscribed. I am using Postfix that delivers directly to procmail which puts mails into Maildir style mail boxes in each users home directory. I am using the dovecot-0.99.13-4.FC2 rpm if that helps. I am sure that there would be some information about this somewhere, but I haven't found it in the mailing lists or googling around. The only information I have been able to find is that dovecot reportedly supports this. Thanks, Mike

[Dovecot] We couldn't drop root group privileges

Hi, I just installed dovecot. The installation went well and i configured dovecot to user ~/Maildir. When I tested imap via telnet the login work, but right after that the connection is cutted: Trying 192.168.0.14... Connected to op. Escape character is '^]'. * OK dovecot ready. . login jerik password . OK Logged in. Connection closed by foreign host. And the log says: dovecot: Apr 02 19:37:18 Info: Dovecot starting up imap-login: Apr 02 19:38:03 Info: Login: jerik [192.168.0.23] imap(jerik): Apr 02 19:38:03 Fatal: We couldn't drop root group privileges dovecot: Apr 02 19:38:04 Error: child 15194 (imap) returned error 89 So the problem is that dovecot "could't drop root group".

[Dovecot] Multiple auth method problem

Hi, I'm having issues getting the multiple authentication methods of dovecot 1.0-test65 to work correctly on NetBSD.

[Dovecot] Trouble with basic Dovecot setup
by paul wisehart 03 Apr '05

03 Apr '05

Hi, I have compiled dovecot-1.0_stable. (http://dovecot.org/nightly/stable/dovecot-stable-20050328.tar.gz) I have it set to "userdb = passwd" & "passdb = passwd" I have a user "wise" with an maildir type mailbox at ~/Mail The actual maildirs are all subfolders with the INBOX "inbox" being one of them. I also have setup the ssl certificates with the script from the source doc directory. I start dovecot, and try to login from a seperate machine running thunderbird. I tell it to use ssl ( 993 ). (I specified both dovecot logs in the config file.) This is what I get from the dovecot logs: "info_log_path = /etc/dovecot/info.log": dovecot: Mar 29 08:30:15 Info: Dovecot v1.0-stable starting up dovecot: Mar 29 08:37:44 Info: Dovecot v1.0-stable starting up dovecot: Mar 29 08:39:04 Info: imap-login: Aborted login [###.###.###.###] I get that last line every time I try to connect from thunderbird. Any ideas? I can give more detailed info as well. thanks! -- paul \ / wisehart >/ <//////$> |\|\|\ -- paul \ / wisehart >/ <//////$> |\|\|\

[Dovecot] QUOTA support timeframe? (also -- folders in folders?)
by Gerald V. Livingston II 03 Apr '05

03 Apr '05

I see it's been in the wishlist a while. Any possible timeframe for getting it working, or maybe a patch (or is it too big a change) to support it? I'm building a new server to move an existing userbase to. So far I have working: Postfix (with Maildir quota patches that work fine) Amavis-new with ClamAV scanning for viruses (will add SpamAssassin soon) SquirrelMail IMP (Horde) (Yes, 2 webmails to allow customers a choice of interface) Right now my test accounts have quotas, but they have no way to see where they stand without IMAP++ QUOTA support. Also, a question. Does Dovecot support folders within folders other than INBOX? I hadn't even thought about that question until I tried to create a test folder from within Squirrelmail and checked the "Let this folder contain subfolders" box and the creation failed ---- nevermind, that must be a Squirrelmail oddity. I created another folder inside the test folder and it worked OK -- just have to NOT check that box. Thanks all, Gerald

Dovecot does not do this. And I don't see a need for that. Configure your MTA to put the envelope data into the mail header (e.g. Return-path and Envelope-to). I used this several times for multidrop-mailboxes (which also seems to be the main use of SDPS).

[Dovecot] virtual user question
by Steve Hoffman 03 Apr '05

03 Apr '05

I'm sorry if this has been asked already, but I'm new to the list and to dovecot. I'm trying to add imap to our existing setup where we host many virtual domains and would like to use dovecot to do it as I find it's one of the most configurable I've seen so far. The problem is that our virtual users passwd files are kept in seperate directories so /etc/virtual/%d/passwd, but I can't use the variable substitution in the dovecot.conf file as it results in a load error because it won't translate the %d. I'm using the latest development release, test65. I read in the config file that you can use many passdb's but do I have to put them all in there or is there a way to use some sort of substitution? The other issue I'm having is when I try to test the connection (with a hard coded path to passwd) it fails auth if I pass the username "user(a)domain.com" but passes if I pass just "user". Any help or places you can point me for these issues? Thanks, Steve

[Dovecot] new to dovecot, dealing with MH foders
by jerry scharf 03 Apr '05

03 Apr '05

Hello, I'm sorry if this is a repeat, a few choice searches into google didn't help and I found no search for the archives. I can no longer put of moving away from UW-IMAP. Dovecot certainly seems to be the right choice, but I am having problems getting it to do what I need it to for all my mail. The machine is running the dist version, 0.99.12. I have a system mailbox and a large MH mail tree (~25K messages.) I saw that dovecot didn't support mh trees like UW did. It looked like maildir would be a good common target. So I found a script that would convert the mbox to maildir and have adjusted postfix, and that all works fine. Then I found mh2maildir, and ran it over my entire mh tree. Then I tried just for a test copying one of the small top level directories under ~/Maildir, but my MUA (mulberry) doesn't see it. So how do I get dovecot to see things other than the inbox in maildir format? How can I easily test to see if it's dovecot's problem or the MUA? thanks for any help, jerry Jerry Scharf laguna way consulting

[Dovecot] dovecot-1.0-test65 + mysql build problem (sha1_result)
by Michael Goth 03 Apr '05

03 Apr '05

Hello all! When trying to build dovecot-1.0-test65 with mysql support I get the following error: ... /usr/local/mysql/lib/libmysqlclient.a(sha1.o)(.text+0x5c): In function `sha1_result': : multiple definition of `sha1_result' ../lib/liblib.a(sha1.o)(.text+0x830):/usr/local/src/dovecot/dovecot-1.0-test65/src/lib/sha1.c:242: first defined here /usr/lib/gcc-lib/i586-suse-linux/3.3.1/../../../../i586-suse-linux/bin/ld: Warning: size of symbol `sha1_result' changed from 158 in ../lib/liblib.a(sha1.o) to 126 in ../lib/liblib.a(sha1.o) collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot/dovecot-1.0-test65/src/auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/src/dovecot/dovecot-1.0-test65/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/dovecot/dovecot-1.0-test65' make: *** [all] Error 2 The version of mysql I'm using is 4.1.10a. Could this mean that dovecot uses a function ('sha1_result') that already exists in libmysqlclient.a? If not, can someone perhaps point me into the right direction where to look for the error? I can provide more details about my setup, if needed, of course. Regards, Michael

In CVS pass_query can now return "user" column to replace the username that was used to log in. Besides fixing character casing problems, it also allows login aliases.

[Dovecot] FC2 POP3/SMTP Configuration
by Linux Stuff 03 Apr '05

03 Apr '05

OK, let me try this again. . . . I'm a newbie to dovecot and a little bit less of a newbie to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run dovecot (v0.99.14) POP3 and sendmail (8.12.11-4.6) with Mozilla (1.4.2 and others), Thunderbird (1.0.2) and Netscape (7.1 on PC's, etc) mail clients - mostly PC's (W2K, WXP). They all can read their mail but none of the users can send any mail. I have also tested with Outlook and it works!? Ximian Evolution (1.4.6) also works!??? Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database Why do Outlook and Ximian work and the others do not? I know I must be missing something in my config file. Ideas?? Thanks

[Dovecot] LDA Wishlist idea
by Mark Lidstone 02 Apr '05

02 Apr '05

Hi all, Sorry if this is out of place, but I've seen people suggesting future functionality for Dovecot on here before. TBH I'm not completely sure if this would be possible in a LDA. Demon (an ISP) have extensions to POP3 they call "SDPS" - there's basically an extra command that can be called for an email and it gives the envelope rcpt and from addresses. I was wondering if there was any chance of future versions of Dovecot allowing something similar?

Re: [Dovecot] [ #14832]: Capital letters in POP3 logins
by Gerald V. Livingston II 02 Apr '05

02 Apr '05

I just tested and IMAP doesn't ignore case either. Remove the UPPER CASE maildir created by your POP3 login then do the same thing with an IMAP client. Set up the IMAP client to use an UPPER CASE username and when you log-in/refresh folders it creates the new UPPERCASE empty Maildir all over again. Crap, between this and the missing QUOTA feature I guess I'm gonna have to rip out Dovecot and use Courier. I really wanted to use Dovecot for it's speed with the indexing. What I don't understand is -- all usernames in my test database are stored in lower case -- shouldn't it simply fail to match and cause the login to fail? Can anyone point out how to force the match to be case sensitive? I'll investigate and get back to the list. It would be "nicer" though if Dovecot converted all username input to lower case before authenticating to maintain uniqueness of email addresses.

[Dovecot] Anybody tracking the GSSAPI patch?

Hey all, I'm doing some Kerberos stuff at work, and I'm thinking it'd be nice if dovecot had GSSAPI support. I found http://dovecot.org/list/dovecot/2004-July/004039.html (thanks Colin :), but it's a long ways away from applying to the current stable tree. I'm wondering - has anybody else been keeping a local copy of this patch up to date? Thanks, Dave -- Arguing with an engineer is like wrestling with a pig in mud.

[Dovecot] test65 killed by SIGSEV
by Thomas Hummel 31 Mar '05

31 Mar '05

Hi, I had successfully set up dovecot-1.0-test62 + ldap pass/user db, but now I'm encoutering a SIGSEV problem with a similar set up of a brand new dovecot-1.0-test65 installation. The auth process is killed by a SIGSEV as reported in the error log file : dovecot: Mar 30 17:06:59 Error: child 28291 (auth) killed with signal 11 To be precise, the problem occurs in the "ldap_lookup_pass" function (auth/passdb-ldap.c) just before loging the ldap request parameters (auth_request_log_debug) and to actually perform the search (db_ldap_search). The signal occurs on the call of t_strarray_join(attr_names, ",") What I'm observing is that the "attr_names" array of the "passdb_ldap_conn" ldap connection doesn't seem to hold the right attributes : while in the test62 version it holded 'uid' and 'userPassword', it holds now 'uid' and 'homeDirectory'. As a matter of fact, the content of this array seem to change between the "preinit" and "init" passdb function and I'm not quite sure this is legal. So my client (actually just a test through telnet) gets a 'NO Temporary authentication failure'. Here's a gdb backtrace of the process : ------- Program received signal SIGSEGV, Segmentation fault. 0x08065bf6 in t_strarray_join (arr=0x807aa20, separator=0x8067b1a ",") at strfuncs.c:571 571 len = strlen(*arr); (gdb) bt full #0 0x08065bf6 in t_strarray_join (arr=0x807aa20, separator=0x8067b1a ",") at strfuncs.c:571 alloc_len = 8 sep_len = 1 len = 9 pos = 39 needed_space = 0 str = 0x806e488 "uid,homeDirectory,,,uidNumber,gidNumber" #1 0x080578a1 in ldap_lookup_pass (auth_request=0x8077a10, ldap_request=0x8077ab0) at passdb-ldap.c:181 conn = (struct ldap_connection *) 0x807a810 vars = (const struct var_expand_table *) 0x807a9a0 attr_names = (const char **) 0x807aa08 filter = 0x806e268 "(&(objectClass=posixAccount)(uid=dovetest))" base = 0x806e468 "ou=personnes, dc=pasteur, dc=fr" str = (string_t *) 0x806e268 #2 0x08050947 in auth_request_verify_plain (request=0x8077a10, password=0x806e198 "pass", callback=0x8054790 <verify_callback>) at auth-request.c:261 passdb = (struct passdb_module *) 0x806b9e0 result = -1077941592 cache_key = 0x646975 <Error reading address 0x646975: Bad address> __PRETTY_FUNCTION__ = "auth_request_verify_plain" ---Type <return> to continue, or q <return> to quit--- #3 0x0805486e in mech_plain_auth_continue (request=0x8077a10, data=0xffffffff <Error reading address 0xffffffff: Bad address>, data_size=6580597) at mech-plain.c:62 authenid = 0x806e181 "dovetest" error = 0xbfbfeaf8 "(ë¿¿²ø\004\b\020@\b\b\034\020\b\b(ë¿¿dø\004\b\002" pass = 0x806e198 "pass" i = 0 count = 2 #4 0x08051a80 in auth_request_handler_auth_begin (handler=0x8084010, args=0x808101c "1\tPLAIN\tservice=IMAP\tsecured\tlip=127.0.0.1\trip=127.0.0.1\tresp=AGRvdmV0ZXN0AHBhc3M=") at auth-request-handler.c:327 len = 20 mech = (struct mech_module *) 0x0 request = (struct auth_request *) 0x8077a10 list = (const char * const *) 0x806e114 name = 0x806e130 "resp" arg = 0x806e160 "\200á\006\b\016" initial_resp = 0x806e0de "AGRvdmV0ZXN0AHBhc3M=" initial_resp_data = (const void *) 0x646975 initial_resp_len = 0 id = 1 buf = (buffer_t *) 0x806e160 valid_client_cert = 0 ---Type <return> to continue, or q <return> to quit--- #5 0x0804f8b2 in auth_client_input (context=0x80785c0) at auth-client-connection.c:144 conn = (struct auth_client_connection *) 0x80785c0 line = 0x8081017 "AUTH\t1\tPLAIN\tservice=IMAP\tsecured\tlip=127.0.0.1\trip=127.0.0.1\tresp=AGRvdmV0ZXN0AHBhc3M=" #6 0x0805f8dc in io_loop_handler_run (ioloop=0x8078000) at ioloop-poll.c:184 data = (struct ioloop_handler_data *) 0x806d080 pollfd = (struct pollfd *) 0x2 tv = {tv_sec = 1, tv_usec = 999555} io = (struct io *) 0x806d5c0 t_id = 2 msecs = 0 ret = 0 call = 1 #7 0x0805f319 in io_loop_run (ioloop=0x8078000) at ioloop.c:218 No locals. #8 0x080541dd in main (argc=1, argv=0x1) at main.c:311 foreground = 0 (gdb) ------- Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Pine and prefix - LIST command bug?
by Chris Wakelin 31 Mar '05

31 Mar '05

I've been having problems with Pine 4.62 talking to Dovecot 1.0 stable. It's fine when the folder collection path is empty, but if I have "~/mail/" or "mail/" it gives access errors (I'm using the "~/mail/", "mail/" etc. hidden namespaces for backwards compatability). It seems to me that Dovecot is not replying correctly to a "LIST" command with empty mailbox name: - Dovecot: xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" "" xyz LIST "mail/" "" * LIST (\NoSelect) "/" "" UW-IMAP; xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" ~/ xyz LIST "mail/" "" * LIST (\NoSelect) "/" mail/ RFC 2060 says: An empty ("" string) mailbox name argument is a special request to return the hierarchy delimiter and the root name of the name given in the reference. The value returned as the root MAY be null if the reference is non-rooted or is null. In all cases, the hierarchy delimiter is returned. This permits a client to get the hierarchy delimiter even when no mailboxes by that name currently exist. Mind you, it looks like at least our UW-IMAP also gets it wrong for "~/mail/". Of course, I may be misunderstanding something!

support(a)majordomo.ru wrote: > Can I solve this problem or it is virtually "bug" of dovecot? No bug, just the "garbage in, garbage out" principle. Mysql's string matches are case-insensisitive by default, so when dovecot asks mysql for the user information of UsEr1, it will get the information of user1 and therefore assumes that UsEr1 is a valid login. It's not dovecot's fault. If you want the match case-insensitive (so UsEr1 will be rejected), add the BINARY attribute to the userid field or change your query to '... WHERE BINARY userid = "%u"' in password_query and user_query. If you want to allow logins as UsEr1 (and let him access user1's mail), you have to change your dovecot.conf, I think. Use %h instead of %u there, and let user_query return the home directory with something like 'SELECT CONCAT('/var/spool/vmail/',LOWER(userid)) AS home, ...'.

[Dovecot] [ #14832]: Capital letters in POP3 logins
by support＠majordomo.ru 30 Mar '05

Hello all! I'm newbie here :) Using dovecot (version 1.0-test59, with mysql-auth) I saw strange problem: after authentication by POP3 in case that username given has capital letters, for example SupportTeam(a)majordomo.ru, dovecot creates new maildir 'SupportTeam' for this username instead reading mails from existing maildir 'supportteam'. Then dovecot scans created maildir 'SupportTeam' and returns 0 messages (sure:). IMAP4 works fine in the same time. Can I solve this problem or it is virtually "bug" of dovecot? Thanks in advance!

[Dovecot] Chrooting dovecot.
by BSD Mail 30 Mar '05

30 Mar '05

Greetings, I have installed Dovecot under FreeBSD 5_3 It is pretty impressive. I got SSL working with no problem for both imap and pop3. Besides that I do still want to chroot Dovecot. I noticed that there are some options in the dovecot.conf that are intended for this. Unfortunately online resources on how to do that can't be found on google. Although I'm running the server as user dovecot. I still do have this: dovecot pop3-login 491 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 490 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 489 1 tcp4 10.0.1.4:995 *:* dovecot imap-login 488 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 487 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 486 1 tcp4 10.0.1.4:993 *:* root dovecot 481 5 tcp4 10.0.1.4:993 *:* root dovecot 481 6 tcp4 10.0.1.4:995 *:* Fine for the first six lines it's doing what it's doing. But the last two lines are running as root. That is why I want to chroot the server. I would like if anyone can point me to some howto or notes on how to do so. If there is none I will have to configure a jail just for this purpose. Thanks in advance. -- Regards,

[Dovecot] Compile Error in current CVS
by Todd Burroughs 30 Mar '05

30 Mar '05

Had a small error with the current CVS version. It was in deliver.c. Here's a fix. I'm assuming that adding NULL is correct ;-) dovecot.2005-03-29/src # diff deliver/deliver.c.orig deliver/deliver.c 86c86 < box = mailbox_open(storage, mailbox, MAILBOX_OPEN_FAST | --- > box = mailbox_open(storage, mailbox, NULL, MAILBOX_OPEN_FAST | Here's the symptoms: deliver.c: In function `save_mail': deliver.c:87: warning: passing arg 3 of `mailbox_open' makes pointer from integer without a cast deliver.c:87: error: too few arguments to function `mailbox_open' make[3]: *** [deliver.o] Error 1 make[3]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src/deliver' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29' make: *** [all] Error 2

[Dovecot] Checkin 1.37 of src/lib-storage/mail-storage.c
by Geo Carncross 29 Mar '05

29 Mar '05

Checkin 1.37 of src/lib-storage/mail-storage.c added a parameter to mailbox_open() but this broke building src/deliver/deliver.c as revision 1.2 doesn't use the new parameter. It looks like save_mail() of src/deliver/deliver.c calls mailbox_open() and it looks like it might work fine if it were to use a (struct istream *)0 as the third parameter (instead of the flags) -- but I don't use deliver [yet], so I don't have any adequate way to test this. -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] mbox zlib compression plugin
by Timo Sirainen 29 Mar '05

29 Mar '05

Some people have been asking this forever, but because it wasn't possible to implement it as a plugin, I hadn't done it. Now, due to some API changes for other purposes, it was suddenly easy. So, if you want to try it, grab the latest CVS code / nightly CVS snapshot and http://dovecot.org/patches/1.0/zlib-plugin.tar.gz Compilation instructions inside zlib-plugin.c file. What it does is check if mbox name ends with ".gz", if so it opens it as read-only using zlib. If the file isn't actually zlib compressed, zlib seems to be able to still access it as a normal file (but it's still read-only). It should be possible to implement it for maildir files as well by hooking into mail_get_stream().

[Dovecot] FC2 POP Configurtion
by Linux Stuff 29 Mar '05

29 Mar '05

I'm a newbie to dovecot and a little bit less of a newbit to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run sendmail with netscape mail clients - mostly PC's. They all can read their mail but none of the users can send. Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database I know I must be missing something, probably trivial. Does someone have a simple, easy-to-read, config file for dovecot pop running with sendmail? Thanks

28 Mar '05

Hello, I have some problems. I am getting the error: Mar 28 21:24:01 APOLLO imap(alex(a)mydomain.nl): Failed to create storage with data: mydomain.nl/alex What is wrong with it? I think it has something to do with the rights or something. Can anyone tell me what to do? Thank you, Alex
