[dovecot] 0.99.9-test3
by Timo Sirainen 15 Apr '03

15 Apr '03

Expunging messages caused those "Corrupted index file" errors. That's fixed now. There's probably still some problems, at least this fix didn't fix any crashes.. test3 available from http://dovecot.procontrol.fi/test/

[dovecot] a crashy message
by Moe Wibble 15 Apr '03

15 Apr '03

Hi everyone, the attached message does reliably crash my dovecot when trying to access a folder containing it. Crash notice in mail.log: Apr 13 17:36:12 rafter dovecot: child 23215 (imap) killed with signal 11 My `dovecot --version` says: 0.99.8 Has this problem been fixed in current dovecot? For now I have just quarantined the offending message but obviously I need to upgrade my dovecot soon because I don't like such kinda things to happen. best regards! -- MW

[dovecot] Three *very* strange bugs
by Warren Togami 15 Apr '03

15 Apr '03

* Attached is a mbox file that triggers Bug #1 and #2. * Go here if you want to test dovecot for RH9: https://bugzilla.fedora.us/show_bug.cgi?id=160 * If somebody has a different IMAP server than dovecot, could you please test how Evolution reacts to reading this message? Bug #1 dovecot and #2 evolution-1.2.3 ===================================== I am using dovecot-0.99.9-test3 on RH9, reading mail with evolution-1.2.2-5 on RH9. Whenever I attempt to view this one particular spam message, evolution pops up an error like: Error while 'Retrieving message 4': Server unexpectedly disconnected: No such file or directory Simultaneously this appears in my /var/log/maillog: Apr 15 01:44:50 server dovecot: child 20328 (imap) killed with signal 11 If I attempt to keep reading mail, it logs in again to dovecot and works normally until I attempt to read that spam again. Evolution displays the error popup again though I don't see another signal 11 in maillog. After this point I am unable to log back into dovecot without restarting the daemon. Here's the strange part... I browsed the same IMAP folder from KMail, and kmail has no problem reading that spam message. dovecot's [imap] process does not segmentation fault. Does this mean an evolution bug when reading this particular spam exposed a dovecot segmentation fault? Bug #3 kernel? ============== This is an unrelated bug and perhaps not the fault of dovecot. When I attempted to use strace to get some debugging info on the [imap] process, this happened: [root@server /]# strace -p 20486 trace: ptrace(PTRACE_SYSCALL, ...): Operation not permitted detach: ptrace(PTRACE_DETACH, ...): Operation not permitted [root@server /]# This isn't normal right? After doing this, dovecot stops working and I need to restart the daemon in order to establish new connections. That [imap] process becomes unkillable, even kill -9 wont work. Unkillable process usually means kernel bug, right? warren 20345 1 7 01:46 ? 00:00:34 [imap] This is kernel-2.4.20-9 in Red Hat Linux 9. Is dovecot exposing a Red Hat kernel bug when I try to strace that process, or is strace supposed to fail, the dovecot daemon ceases to function and [imap] process becomes completely unkillable? =) Warren Togami warren(a)togami.com

[dovecot] dovecot RPM for Red Hat Linux
by Warren Togami 14 Apr '03

14 Apr '03

http://bugzilla.fedora.us/show_bug.cgi?id=160 This .src.rpm is dovecot with RH-specific default settings. I modified Jeremy Katz' dovecot-0.99.8.1 package a bit. When I upgraded from 0.99.8.1 it seemed to be broken until I looked at /var/log/maillog. There it indicated that the dovecot cache files were bad, so I erased /home/*/mail/.imap/ and it seemed to work subsequently. There are a few more RH specific tweaks that I plan on doing for this package. If you have any suggestions to default config tweaks for this package please reply or post in that bugzilla entry above. I would like for this package to be a drop-in replacement for RHL's uw-imapd eventually, but there are a number of migration issues that need to be addressed first. This package will eventually be included in the Fedora tree after it goes through our QA. http://www.fedora.us Fedora Linux is a project of volunteer package developers making 3rd party packages specifically for Red Hat Linux. Warren Togami warren(a)togami.com p.s. Keep up the good work. I absolutely love dovecot!

[dovecot] Something wrong in SSL ?
by Juha Ylitalo 14 Apr '03

14 Apr '03

Operating system: FreeBSD 4.7-RELEASE-p10 Dovecot: 0.99.8.1 I've used openssl to generate personal CA and I've used that one to generate certificate for my web server. When I tried to go through same pattern for generating certificate for IMAP server from CA, I ended up in situation, where both mutt and evolution keep on rejecting my certificates.

[dovecot] Maildir problem?
by Maikel Verheijen 11 Apr '03

11 Apr '03

Hey list, Today I cvs updated to the most recent dovecot, to test with the recent improvements on the dovecot-uidlist file, and came acros the following: Apr 11 12:49:36 pc-5-046 imap(): Corrupted index file (in-memory index for /var/mail/mounted/test.com/maikel/Maildir//.Sent Items): Filename mismatch for UID 1: 1050058115.P3401Q0M675362.pc-5-046.test.nl:2,S vs 1050057888.P3371Q0M138398.pc-5-046.test.nl I am using a front-end back-end construction, But I am testing on the backend only (non-nfs), because the subscriptions file isn't nfs safe yet. shouldn't the uidl files be leading over the indexes? And shouldn't the indexes be updated as well? Thank you, Maikel Verheijen.

[dovecot] Maildir syncing rewrite
by Timo Sirainen 11 Apr '03

11 Apr '03

It finally seems to be working. I've done some testing now and it seems to be working fine. If you have time, see if you can get it to break (especially with INDEX=memory or by manually modifying the maildir). The UIDs are kept in Courier-compatible dovecot-uidlist file (so "mv courierimapuiddb dovecot-uidlist" should work). The great thing about this code is that we never wait for lock. If we can't lock, we simply use the old uidlist file to sync whatever we can, which should be everything but the very newest mails just being delivered and processed by another Dovecot. Of course, if they share index files, we're still blocking there. I named the file as "dovecot-uidlist" instead of ".uidlist" because I finally realized that files beginning with dot conflict with the mailbox namespace. I should rename .customflags and .subscriptions files as well. Also if I move .imap.index* files into root dir, I'll have to rename them too. new/ directory is now scanned every time to see if there's new mail. cur/ directory is scanned if index file's timestamp differs from cur/ dir's timestamp. uidlist file is reread if it's device/inode changes. You can get the sources from either CVS, or 0.99.9-test2 from http://dovecot.procontrol.fi/test/

[dovecot] compilation errors
by Mark E. Mallett 11 Apr '03

11 Apr '03

Hi- I always encounter the same two minor compilation issues which are easily addressed simply by a quick edit, but this time I figured I'd mention it in case you can work around it. This is on a BSD/OS 4.2 system. First, the generated config.h always creates a definition for OFF_T_MAX which conflicts with the one in the system's limits.h config.h defines: #define OFF_T_MAX LLONG_MAX whereas /usr/include/machine/limits.h defines: #define OFF_T_MAX UQUAD_MAX /* max value for an off_t */ I simply comment out the definition from config.h . Second, in src/lib/mmap-anon.c there's a preprocessor conditional: #if SSIZE_T_MAX >= LLONG_MAX (etc) Unfortunately /usr/include/machine/limits.h defines LLONG_MAX thusly: #define LLONG_MAX (__extension__(9223372036854775807LL)) (evidently to suppress pedantic warnings about the gcc long long constant extension) but the cpp prepreprocessor stumbles over this comparison. This might be fixed in a later gcc, I dunno- it's gcc 2.95.2 here. Yours, -mm-

[dovecot] dovecot and virtual users

Hello, I set up a virtual smtp with exim (mails stored in /var/virtual/{domain}/{user}, passwd in /etc/virtual/{domain}.passwd). I have a patched pop3 server to deal with these mail boxes. Would it be possible to use dovecot as imap server, or (even better) for imap and pop3, with this virtual domain model ? Thanks, read you. -- jej

[dovecot] New installation - error 89 on connect
by David Knudsen 09 Apr '03

09 Apr '03

I've recently installed dovecot (0.99.8.1) from the Debian/woody backport at 'deb http://src.braincells.com/debian woody/' Previously, all mail have been delivered to mbox'es in ~/Mail by exim/procmail -- ~/Mail/inbox being my main mailbox. Whenever I attempt to connect with an IMAP client, the connection is closed and the following error is reported in /var/log/syslog: imap-login: Login: dk [192.168.0.2] imap(dk): Unknown client workaround: outlook-idle^I### dovecot: child 17653 (imap) returned error 89 What does error 89 signify? My current configuration is: (non-comment lines only) imap_listen = 192.168.0.2 imaps_listen = * login = imap login = pop3 verbose_proctitle = yes client_workarounds = oe6-fetch-no-newmail outlook-idle mailbox_check_interval = 60 auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes In my confusion, I blindly tried changing settings, attempting to get a different error message at least. :-) These are the settings I have tried, without success: default_mail_env = mbox:~/Mail:INBOX=~/Mail/inbox mail_full_filesystem_access = yes mbox_locks = fcntl auth_passdb = shadow There is no subdirectories in ~/Mail, neither visible nor hidden. I did try to read the docs, and I did browse the mailing list archives, but either I missed something or it is not there. Any ideas? Thank you, David Knudsen

It should look into ~/Maildir first, then ~/mail and ~/Mail unless it's overridden in MAIL environment. You probably have MAIL=/var/mail/user set, which is why it looks into there. Currently it doesn't read any configuration file, and I'm not sure if I should make it do that.. Well, it could be useful but I'd have to figure out how to prevent unneeded code duplication for config file parsing.

There's the "imap" binary that should do exactly that. Usually installed into /usr/local/libexec/dovecot/imap Or did you mean you wanted to run it from inetd? CVS version supports that too if you execute imap-login.

Hi, jaldhar recommended dovecot to me - http://www.askbjoernhansen.com/archives/2003/04/07/000286.html ... and so far it seems much nicer than the other imapds. yay. I use the OS X Mail.app client. I tested it with a test account with no problems, but trying to use it with my usual mail folders (~1.3GB; 120MB in the inbox) it's not working at all. It seems like dovecot keeps copying the full inbox into a temp file in mail/.imap/INBOX. It did it at least 10 times while I was watching without any noticable progress doing anything at all in Mail.app. I am running FreeBSD on an ancient box with 384MB ram (but nice SCSI drives). I tried stopping new mail deliveries to the inbox while I testing, but it didn't seem to make a difference. - ask -- ask bjoern hansen, http://www.askbjoernhansen.com/ !try; do();

Is this just for courier compatibility, or is > there a deeper reason why it can't be changed? Actually I'm going to change it to '/' to allow folders such as shared/timo.sirainen/mailbox. The directory names themselves will still contain '.' separator to stay compatible with Courier's Maildir++ format. So even though new IMAP separator will be '/', '.' still can't be used in mailbox names.

[dovecot] a few other problem

hi, I still has a few other problem with dovecot and mozilla. - when I open mozilla mail I can only see the toplevel folders in the left handside folder list and when I close the imap folder and open it again (click on the arrow left to the imap server in the folder list) mozilla show me all folders and subfolders correctly (but not at the startup). it can be mozilla's bug, but this was worked when I use courier?! - when I'd like to sort the messages by thread than the thread is usualy ok, but I'd like to see the the different threads sorted by date (as it was while using couirer or cyrus) but now it seems to me random:-(( it's very anoying. my be it's mozilla fault again, but may be mozilla use server side thread support. - in OE6 when we only select headers only sometime some message "disappear"! which means we see in OE6 a red line over the message (as it would be deleted), but no one delete it (yes I know you don't belive me, I also don't belive our users, but once I saw it). just click on it to see the message and inmediately become as deleted. while when I look at in the server the file is still there and _not_ deleted. and OE6 show "the message already removed from the server". - what about the ssl (imaps) problem? yours. -- Levente "Si vis pacem para bellum!"

So in a way, a lot of info COULD come from my database, if it isn't safe enough via nfs. Can you make all file locking configurable? Or will you do it on a "per-type" basis?

[dovecot] Failure in the presence of too many connections
by Mark E. Mallett 02 Apr '03

02 Apr '03

Had an event today where dovecot refused new connections and would not accept more until restarted, whereupon it worked for a few minutes and locked up again. Looking at the logs it appeared that it had run out of file descriptors. I increased the open files limit and started it again-- which worked but it only pushes off the problem. Does dovecot keep an open file descriptor for every imap or pop3 child? If so, this would argue more towards a tcpserver sort of control. If not, perhaps something is leaking.. -mm- PS: assume you saw recent RFCs 3501 and 3502 ?

[dovecot] NFS mounted IMAP dirs
by Maikel Verheijen 31 Mar '03

31 Mar '03

Hi list, I am trying to build an email system that is using multiple frontends, to a clustered backend using nfs. The backend mounts his filesystems from a central storage, and will be running active-active. While reading through the dovecot documentation, I read that I could do without indexes (well: use memory indexes), and could then be able to run dovecot over NFS. Well: that was until friday, when I was reading a little bit better through nfs.txt. :) My problem is now that dovecot writes it's subscriptions to the mailstore. Since I want as little difference between my frondends as possible, (and as static as possible), I would love to see dovecot handle subscriptions in a database, or perhaps a nfs-safe file. Since I am only a junior programmer (my code is really not far from "Hello world", although I am trying to find some time to teach myself more), I might not be able to be of much assistance to you all in coding stuff, but I am willing to help out where-ever possible. Can anyone help me solve my problem in any way, and how can I contribute as well? Thank you all, Maikel Verheijen.

[dovecot] FETCH BODY[part]<partial>
by Jesse Peterson 29 Mar '03

29 Mar '03

2003-03-24 12:59 Timo Sirainen <tss(a)iki.fi> This CVS update didn't actually seem to fix the problem. I still get the problem as before, like this capture: 10 UID FETCH 60 BODY.PEEK[]<8192.1915> * 60 FETCH (UID 60 BODY[]<8192> {1915} ) 10 OK Fetch completed. Not quite 1,915 bytes =). Perhaps the "[]" (without a part) is confusing it? But still, it grabs the first chunk correctly. At any rate, any input would be great.

[dovecot] Dovecot and Quotas
by Mike Machado 26 Mar '03

26 Mar '03

Is there anything that can be done so that when users IMAP to their inbox and have reached their filesystem quota, that they can still DELETE their mail? They can login, but when they go to delete/expunge this is the error I get in syslog. I have tried mail_read_mmaped to yes and no, and same result. Mar 25 14:54:27 penguin1 imap(bob): file_set_size() failed with index data file /home/bob/mail/.imap/INBOX/.imap.index.data: Disk quota exceededMar 25 14:54:27 penguin1 imap(bob): mmap_istream.madvise(): Function not implemented Mar 25 14:54:28 penguin1 last message repeated 65 times When using UW IMAP, sometimes users can delete mail and other times they cannot. I am desperately seeking a solution to have customers be able to delete their own mail when their box is full and not have to call our support center. Any suggestions? Thanks.

Maybe there could be a "toggle" to do or don't create the dirs, so you don't need the mail_global_dir setting for "normal" use. My idea was to check the full path to the mailbox, and to create the nonexisting part if necessary. At that point you DO have the full path to the mailbox/maildir, and you can create it, right?

[dovecot] inetd/xinetd/tcpserver support
by Timo Sirainen 26 Mar '03

26 Mar '03

I was just thinking how they could be easily supported. This would work, right? : imap stream tcp nowait root /usr/sbin/tcpd /usr/local/libexec/dovecot/imap-login imaps stream tcp nowait root /usr/sbin/tcpd /usr/local/libexec/dovecot/imap-login --ssl imap-login would try to connect to master process using some named socket. If it couldn't, it would create the master process itself. Master process would work as usual (executes auth and imap processes), except it wouldn't be executing login processes. This wouldn't require much code changing, and it would still be using all the same privilege separations as the standalone version so it would be just a secure. Only thing I'm wondering is if any of the TCP wrappers care about the created child processes? The master process would have to stay alive after the connection that created it dies. I guess I'll implement this soon and try if it works.

[dovecot] mailbox problem
by Maikel Verheijen 26 Mar '03

26 Mar '03

Hi list! Since a week I am testing with dovecot, and I must say, I like it a lot :) Keep up the good work :) I do have one questing regarding dovecot: If I login to a mailbox, and the mailbox does NOT exist, and the parent directory does not exist either, I will get disconnected, and dovecot claims it cannot create the directory. (eg: my user blah(a)test.com has mail directory /var/mail/t/te/test.com/blah/Maildir, and all directories up to /var/mail/t/te/ exist, dovecot does not create the directory test.com/ and on.) Is this by design, or should this be created by dovecot? The problem is solved as soon as the user receives his first email, since my MTA creates the directories... Thank you, Maikel Verheijen

[dovecot] Help
by Barker, Ron, vpe 26 Mar '03

26 Mar '03

Hi to all, We are a bit of newbes to imap etc, so may be we just not doing it right. Nevertheless, We have compiled dovecot to run under Solaris 8/9 for IPv6 test. We are going crazy. After a successful compilation, the troubles really began. Solaris 9 1. Every´time we reboot- the directory /var/run/dovecot/auth is gone ???? 2. After the dir is created manually, the server starts. However!!! 1. A telnet to host 143 connect to the server fine but no commands are accepted. The server simply returns "bad command" 2. If we try to connect via a e-mail client to the server - we get a login refused - which I suspect is simply the "bad command" error being interpreted as such. We have tried every concivable combination of conf items in the conf file but nothing. Solaris8 Just does not start.

[dovecot] some problem with dovecot
by Farkas Levente 21 Mar '03

21 Mar '03

hi, yesterday we switch to courir to dovecot the whole company. there is good and bad news. the good one that about 200 people use outlook and outlook works fine (after we make some registry hack to delete the INBOX form imap root folder, which was required for courier but not for dovecot). the bad news we try most of the thing before the switch except outself. since the whole it department use linux and mozilla. and almost nothing is working with mozilla: - first of all the folder list can't be subscribed i.e. only the top level folder can be subscribed. can't subscribe to folder which has subfolders and mail inside. all folders with has subfolders shonw as an empty name folder under itself. and you can't select these folders in mozilla's subscribe window (i.e you are not able to check it even it is there). - you can't send any messages!!! since mozilla can't find the Sent folder and can't move the mail after sending!!! even if you reconfigure mozilla to use that "Sent" folder as Sent folder. - you can't see the mails in a folder which has subfolders i.e. it seem there is no message in that folders. - we store mails in ~/Maildir/. dovecot create a ~/Maildir/.INBOX and put the index files of the ~/Maildir/{cur,new,tmp} into that folder but for all other folders it keep the index files in that folder's directory. it's realy confusing. this is _very_ anoying:-((( is there any dirty trick to use mozilla? when thses will be useable? thanks.

[dovecot] debian 0.99.8.1 packages available
by Jaldhar H. Vyas 20 Mar '03

I thought I'd mention it here because a lot of people have been waiting for me on this. My personal situation is getting saner now so I finally was able to package up 0.99.8.1. The package for sid was uploaded last night and should appear in the archive today. A backport for woody is available from http://www.braincells.com/open/ I have not included POP3, LDAP or SASL2 support for now as I didn't want anything to delay the package from entering the archive. That will be the next order of business. The only bug I've seen so far is that when my mbox-format inbox was in /home/jaldhar/mail/inbox dovecot thought it ha 0 messages. It only showed up properly after I moved it back to /var/spool/mail/jaldhar but I suspect this is just a configuration error on my part. -- Jaldhar H. Vyas <jaldhar(a)debian.org> It's a girl!

[dovecot] big mail problems..
by Jesse Peterson 19 Mar '03

19 Mar '03

Attachments, large mails & etc. seem to have problems with my installations of dovecot. As we know, Mozilla likes to take it's mail in chunks, and after Mozilla, (or Mail.app, it likes to do this, too) takes its first chunk, it doesn't start getting the rest, even though ethereal tells me that dovecot OK'ed the 10K chunk. 9 UID fetch 4 (UID RFC822.SIZE BODY[]<0.10240>) * 4 FETCH (UID 4 RFC822.SIZE 3958069 BODY[]<0> {3958069} <snip> 9 OK Fetch completed. Nothing gets transfered beyond this point. I think this would be mozilla's fault, but I dont think this would happen with a release, and I dont think Mail.app would have the same problem, too. Thanks for any help, - Jesse

[dovecot] Configure SSL problem
by Leslie Viljoen 17 Mar '03

Hi everyone I have been trying to get Dovecot installed with OpenSSL support, but no matter what I do, when I run Configure, it says "Building with SSL support.........No". I have even tried configure --with-ssl=openssl, to no avail. I have built and installed OpenSSL, and libssl.so and libcrypto.so are in the /lib directory - what more does Dovecot want? I have tried figuring it out from the Configure script itself but it's cryptic and I am no shell script boffin!

[dovecot] dovecot/vpopmail auth problems

Hello. I am having problems getting dovecot to authenticate correctly through vpopmail. I have used vpopmail for some time, and I understand how it works. vpopmail is using mysql to store it's authentication data. vpopmail's tools can access the user database just fine, and vchkpw is working so far as authentication goes. I took an "strace -f dovecot", in case it can help. It is about 900k, and can be accessed at http://www.narshe.net/~umaro/dovecot.log please help! Thanks Chris Doyle

[dovecot] Shared Folders?
by Moe Wibble 14 Mar '03

Hello everybody (esp. Timo ;)), in an attempt to replace our cyrus imapd with something less bloated I have recently evaluated some of the younger imapd implementations, namely bincimap and also dovecot. Bincimap didn't work properly with mozilla for me, dovecot hasn't failed on any test, yet. Unfornationally, since we have been using cyrus for over 1.5 yrs, we pretty much depend on the "shared folders"-feature. Are there any plans to make shared folders available in dovecot anytime soon? best regards! -- MW

[dovecot] Starting Dovecot?
by Leslie Viljoen 13 Mar '03

13 Mar '03

Hello! I have laid SSL aside for the time being, and continued compiling and installing Dovecot. Now I don't know how to start it! I have been through the config file and mostly left things as-is. I have created the dovecot user and group and put only dovecot user in the dovecot group. Then I tried imap-master, as specified in the INSTALL documentation, but there is no such file! Under src/master, "dovecot" gets built. I tried running this, and /var/log/messages says "dovecot starting", but this process seems to just end. If I run it twice very quickly, I get told that port 143 is busy - so it seems that it is starting up, but only staying up for a very short while. Messages gives no more clues as to why the server quits. Any ideas?

[dovecot] Apple's Mail.app
by Scott A.McIntyre 10 Mar '03

10 Mar '03

Hi, I solved the OSX Authentication issue; I'm now reliably able to get authenticated using the Password Server with PAM with: # login: auth account password session auth required pam_nologin.so auth sufficient pam_securityserver.so auth sufficient pam_unix.so auth required pam_deny.so account required pam_permit.so password required pam_deny.so session required pam_permit.so As the /etc/pam.d/imap Anyway -- new problem. With Apple's Mail.app and how it wants to download messages into it's cache, I've found that there's a problematic interaction between Dovecot and Mail.app -- but pinning down exactly what and where is proving to be a hassle. I was running Courier-Imap with Mail.app, and that worked without incident (however, the courier-imap server was on Linux, not OSX Server, that will not work (yet) with osx-server). If I use Entourage and Dovecot, it works fine. The primary symptom is that as it downloads messages Mail.app just hangs; no response, the session just freezes. Usually it's when the status bar is saying something akin to "Caching 9 of 506" at which point it stops. The number varies, but it's always in the first couple of dozen. Messages are small, so it's not that it's hanging on a large mail download. I eventually have to forcibly kill Mail.app. The log says nothing of use: dovecot: Mar 07 17:31:23 Info: Dovecot starting up imap-login: Mar 07 16:32:50 Info: Login: scott [194.109.29.21] imap-login: Mar 07 16:33:46 Info: Login: scott [194.109.29.21] imap-login: Mar 07 16:35:38 Info: Login: scott [194.109.29.21] But perhaps there's a more verbose option somewhere.

[dovecot] IMAP Folder paths
by Juergen Kahnert 07 Mar '03

07 Mar '03

Hello, we like to use dovecot, but our old imapd used to store the paths of the folder in the file ~/.mailboxlist. This file contains something like this: mail/read mail/dovecot .netscape/imap/mailbox .Mail/foo Each line with a path to one mbox folder. And please pay attention that there is no path to the inbox, because this is stored on the server... Is there a way to use this files with dovecot? It would be a real pain to change this for a few thousand user... Do you see a chance of using such a file? Or is it already possible and I'd overlooked it? Or is it easy / hard to implement? kind regards, Jürgen Kahnert

[dovecot] OSX & Authentication
by Scott A.McIntyre 07 Mar '03

07 Mar '03

Hi, Taking a stab at getting OSX Server 10.2.4 running Dovecot -- with a minor tweak of replacing lchown() with chown() in the src/lib/sakfe-mkdir.c, it compiled and installed without any problems. However, oddness in authentication. It works once, but only once. I'm trying to use pam and have the following: auth required pam_securityserver.so auth sufficient pam_unix.so account required pam_unix.so In the dovecot.conf I have (amongst other things): auth_userdb = passwd auth_passdb = pam I start up dovecot and do: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. . login scott pass . OK Logged in. . logout * BYE Logging out . OK Logout completed. No problem. However, try it again and: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. . login scott pass . NO Authentication failed. . logout * BYE Logging out . OK Logout completed. Perhaps there's a better way to get dovecot playing under osx; I'd tried a number of ways of using pam, but perhaps there's a magic other option I've not got working yet. I do run the password server and my account name is using that as per the Workgroup Manager's settings (as opposed to Basic)... Any thoughts appreciated! Scott

hi, it seem to me that dovecot support only v2 ldap protocol but openldap2.1 support only v3 (or you can enable v2 in the conf file, but it seems they wouldn't like to support it in the future). will dovecot support v3 ldap protocal? thanks. -- Levente "Si vis pacem para bellum!"

[dovecot] problem with COPY?
by JP 05 Mar '03

05 Mar '03

hi all, I've been trying to use dovecot (from cvs 03.mar.2003, linux 2.2.20, gcc 2.96, openssl 0.9.7a) as an replacement for uw-imap, and it seems to be doing its job, except for one thing: I have my mua (sylpheed-claws from cvs) set up so that it will sort message into certain(imap) directories. so when I check the mail in the INBOX, new mails will be processed automatically and, for example spamcop related emails are moved to their own 'folder'. imap session below.

[dovecot] Torture tests
by Ian R. Justman 04 Mar '03

04 Mar '03

Hi, all. I've been so impressed with Dovecot, I'm in the process of moving my mail over to it. In fact, one of my mailboxes got SO huge, it'll likely literally take more than a day to move it all over (in excess of 19,000 mails, about 140 megabytes). So far, the IMAP server shows absolutely no sign of crapping out yet. It should also be noted that I'm moving all this mail out of a Cyrus mailstore into an mbox folder on the same server using Pine. And at work, for my work mail, I recently installed Dovecot 0.99.8, using the POP2 port so I can have test it out while not disturbing my coworkers' ability to retrieve mail. So far, I have yet to see anything bad happen. My IMAP test is taking place under Debian GNU/Linux Woody and my POP3 test under FreeBSD 4.7-STABLE. Though any suggestions in what to keep an eye out for in either case? --Ian.

[dovecot] pine/dovecot issues
by David E. Storey 04 Mar '03

04 Mar '03

Folks, I'm running into some issues with pine and dovecot. (dovecot is running mbox for now... plan to switch to maildir soon.) At first I thought it was a funky issue with the way I was using pine to access mailboxes. (I use rsh to invoke imap as pre-authenticated so when I switch to maildirs, I don't have to worry about pine being patched to support it.) But after switching over to using authenticated IMAP over port 143, it still had issues. I'm getting messages like: Junk in start of group Not an Address Junk at end of envelope Unknown Message property Thus far, it seems to only occur in pine. (Squirrelmail and evolution appear to be fine) Is it the client? Is it dovecot? is it easily fixable? It feels like some sort of escaping issue or parsing issue or something. I just don't know enough about IMAP to determine exactly what it is. I'm using dovecot v0.99.8, MAIL=mbox:%h/Mail/:INBOX=%h/.mailbox I've just converted off of wu-imap in hopes of someday migrating to maildirs on that box. (anyone know of a good mbox to maildir conversion tool? I used to have on that worked fine, but I've since found a ton that don't work well for me at all. I have about a gig of email to backup and convert) d!

Actually, I wouldn't mind seeing something like this so I can compress up my old mail and perhaps store them on CD, for example.

[dovecot] pop3: last, and auth plain
by Mark E. Mallett 27 Feb '03

27 Feb '03

Hi- A couple of comments regarding the POP3 server (I realize the POP3 server is probably low priority though..) One problem is that the "LAST" command is not supported. Some mail clients end up downloading all messages every time because of this (or so I'm told). The biggest source of these remarks is people using the yahoo webmail front end. I wonder if this could be added? Also, under BSD/OS, the "auth plain" mechanism doesn't work. Perusing the mailing list archives, I see that the symptoms appear just like those that were reported earlier for another BSD system. I'm curious as to whether there has been any progress on that front? Yours, -mm-

[dovecot] 0.99.8 released
by Timo Sirainen 25 Feb '03

25 Feb '03

Hope I didn't forget anything :) v0.99.8 2003-02-25 Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. * Maildir: .customflags location has changed for INBOX. If you have set any custom flags, move Maildir/.INBOX/.customflags into Maildir/.customflags or they will be lost. * mbox: Autodetect /var/mail/%u and /var/spool/mail/%u as INBOXes if they're found and mail_default_env isn't set. * passwd-file: File format changed a bit. If you used realm or mail fields, you'll have to fix the file. See doc/auth.txt for description of the format. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND, UNSELECT, IDLE, CHILDREN and LISTEXT extensions. + LDAP authentication support. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() + New setting: mail_full_filesystem_access allows clients to access the whole filesystem by simply giving the path before the mailbox name (eg. SELECT ~user/mail/box, LIST "" /tmp/%). While this allows users to share mailboxes, it's not recommended since Dovecot's index files can't be safely shared. + New setting: client_workarounds. + Dynamically loadable authentication modules. Binary package builders should consider using it for at least LDAP. + mbox: Content-Length is saved now to each saved message, so it's now safe to have lines beginning with "From ". + mbox: mail_read_mmaped = no works with it now + Indexes can be kept in memory by adding :INDEX=MEMORY to MAIL environment. There's not much point to do this now though, since the UIDs won't be saved. - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - LIST and LSUB rewrite, should fix several bugs in them - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - mbox: when saving mails, internal headers were allowed in input, sometimes causing problems (eg. duplicate headers) when appending and copying messages - mbox: X-Keywords headers were duplicated - Some small fixes to how messages are saved to Maildir - Next command after STARTTLS was ignored which left the connection stuck sometimes - Dovecot was pretty much broken with FreeBSD

[dovecot] Configuration file format changes
by Timo Sirainen 25 Feb '03

25 Feb '03

After tomorrow's 0.99.8 release I think it's time for a new config file format. It could be made backwards compatibile with the old format, but there would be new tree-like categories. I was thinking something like this: # global settings protocols = imap # "foo.server.org" is just descriptive name # settings inside server { .. } will override global ones. # groups (namespace, login settings, auth settings) aren't replaced # unless same name is used. server foo.server.org { imap_listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer # default namespace (no name) namespace { type = private mail = mbox:~/mail } # Have to quote so '#' won't be thought out as comment. # I think quoting should work everywhere actually.. namespace "#maildir" { type = private inbox = yes # this namespace contains INBOX mail = Maildir:~/Maildir } # override global auth default auth default { auth_mechanisms = plain digest-md5 auth_realms = foo.server.org auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot-ldap.conf } } server bar.server.org { imap_listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer namespace { type = private #mail = #autodetect } # shared mailboxes between users # eg. user/timo.sirainen/some-shared-folder namespace user { type = user mail = /home/%u/mail/shared } } server baz.server.org { imap_listen = 1.2.3.6 ssl_disable = yes # Only Courier-like INBOX namespace namespace INBOX { type = private } } # common namespace between all instances namespace shared { type = shared mail = mbox:/var/lists:INDEX=~/mail/.shared/ } auth default { auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam }

It's hung up in SSL_CTX_use_PrivateKey() in ssl-proxy-openssl.c, which as you correctly surmised below, is due to a password protected key. I've located and used mkcert.sh. As a note the only docs for doc/mkcert.sh are halfway through the NEWS file and rapidly receeding as you add new releases, (congrats on the fast progress by the way!), however you might consider adding a short note about it to the doc/auth.txt or doc/configuration.txt file for those new to dovecot. > > > I do call fflush() after each write to log.

After playing a bit, I think that those messages were due to the kill -9, SIGTERM is nicer. I still end up with little in the way of verbose debugging messages, by my standards. Usually all I see is login and logout messages.

If your private key is crypted with some password, > Dovecot can't use it at least currently.. Correct! Doh! I have been able to use imaps, since I built a non-passworded private key. I was using passworded keys that I'd built for Apache, and would eventually like to have one set of keys that I can reference for each virtual domain. Were you planning on something like the Apache startssl option? I can live with the constraint of one 'connection' key for now. Have you considered allowing each virtual domain to have it's own keys? Kind of difficult as the secure pipe to the server is already in place by the time the login name is seen... Kinda makes it tough for a true virtual presence without explicit assigned IP's. Hmmm, any plans for at least a different keys/identity per IP? If I understand the configuration file for now, it seems to be designed for one cert per machine. Thanks for the help, I've just got to sort out the lockfile differences between Exim and Dovecot and I should then be functional. After that I'll start using LDAP. TJ

[dovecot] Trouble setting up dovecot
by Tim Snider 21 Feb '03

21 Feb '03

Hi, I'm new to the list but have been trying to get dovecot configured for the past week and a bit. I've gone through the list archives and solved a few of my problems, but most don't seem to be addressed. First off I want to say thanks for starting this project, I've been hoping that someone would start an IMAP/POP server with some flexibility in the way it's configured and provides both packages in one.I've tried setting up Courier once and found it onerous, UW was easier but forces a bunch of assumption that don't suit the way I wanted to configure virtual mail. I'd love to run dovecot, eventually with LDAP and Jamm, and Exim to handle my virtual domains, however I'm running into a fair number of problems and haven't had any luck getting past them. I'm running a RedHat 7.3 SMP server, with iptables for a firewall, so I've got several cards and thus IPs.I started out with dovecot 99.4 but noted that it was missing the LDAP, tried 99.8-test5 and am now working with 99.8-test7, both seem to have the same problems. I'm currently trying to setup a IMAP server on the inside of the firewall, 192.168.2.X. If I use just imap, turn of SSL/TLS I'm fine, and can do plaintext authentication via shadow, but I can't get PAM authentication working. If I turn on SSL(ssl_disable = no), neither the imap or the imaps respond and a netstat -tp shows that no process owns the socket PID/process = '-', often with characters in the Recv-Q. I've tried turning on all the debugging flags for configure on, --with-rawlog --enable-debug --enable-asserts --with-ssl=openssl as well as verbose_proctitle = yes, and auth_verbose = yes, setup logfiles /var/log/dovecot/messages, yet all I get are authorization messages. And I've noted that a number of them only show up after I've killed the dovecot process, so I'm wondering if there needs to be a bit of flushing somewhere? As well I've also tried to run "dovecot -F", with the log files commented out in the .conf file, but get nothing via stderr. I note that when I try the log_timestamp option, the dates sent from imap-login are completely incorrect and don't change, so I don't think the date is being read correctly. Is log_timestamp operational? One thing I'm not clear on is what process to run it under, I've setup a user/group 'dovecot', but does dovecot have to be a member of wheel? I've also noted in earlier versions you had things running via imapd-master, but that now seems to been replaced by "dovecot", is that correct? Is anyone else running dovecot on a SMP system? Any comments or suggestions? I do have development experience, but my Linux/UNIX programming is a bit rusty. I'd love to help make this a rocking product, but need some help getting it dovecot up and running. Any help is appreciated. Thanks, TJ timsn(a)thtree.com http://www.thtree.com/People/TJ/Resume.html

[dovecot] 0.99.8-test7
by Timo Sirainen 20 Feb '03

20 Feb '03

OK, I really should release 0.99.8 final soon, but not just yet :) Mostly just documentation updates left I think. There's a few recent changes that might have some nasty bugs: - problems with copying messages from mbox to another should be fixed now - LIST and subscription handling rewritten. - "mail_read_mmaped = no" used to corrupt mboxes when expunging messages. It now enabled again by default, and it seems to be working. I did update my backups though :) Dovecot's LDAP support currently requires that it can read the userPassword field of every user. I'm not sure if I should support "authentication binds" that seems to be more standard way to do LDAP authentication. That's just slower, works only with plaintext authentication and makes my code more complex.

I am NOT speaking to maildir, nor to Cyrus, nor to SQL-enabled products. Solely to mbox. In fact, I even said that stuff that talks to maildir, in addition to Cyrus, offered the one thing for IMAP you could not get with mbox until Dovecot came along; something resembling robust dealing with multiple clients to the same mbox store. Nor am I particularly insterested in debating the merits of any format over mbox, a format I have stated I -KNOW- has annoying technical limitations and issues. While I would imagine other formats may have advantages over mbox, I continue to use mbox simply because of the sheer amount of stored mail I have accumulated on all my machines for the past seven years. My point is that Dovecot seems to be the most robust IMAP server I have come across at coping with mbox stores, especially if I am trying to access the same mailbox with two different clients, whether intentionally or inadvertnetly. My hope is that Dovecot's POP3 server will prove just as robust at dealing with mailboxes that may also be open by an IMAP client. Whether Dovecot, BINC IMAP, or even Courier IMAP (or whichever POP3 server for that matter) are better for maildir or anything else, I will leave that debate to those who actually use them. In the end, I have made a choice. Not necessarily the best one, but I made the choice with the full understanding of what that choice would entail. However, you never know. I may change my mind later. ;) --Ian.

Here is what -I- would say: I use mbox on all my servers which I have absolutely no intention of changing despite the issues concerning file locking inherent in the whole mbox format. So please, --NO-- attempts to convince me to go to maildir. My take is that if I am going to use an IMAP server, it would be VERY nice if a POP3 server also came bundled with it. Dovecot's having both IMAP and POP3 servers is great because they will likely use the same file-locking schemes (in fact, probably even share the same locking settings). That way if I inadvertently start up a POP3 session while I am connected via IMAP, if they use identical locking mechanisms, I don't screw up my mailboxes should I inadvertently tell my system that I want to delete the messages from my mailbox. Basically, if you open via IMAP using a server with a diffent locking scheme while your hung POP3 session is still running AND you modify your mailbox, you are screwed. Especially if that mailstore is NFS-shared, which is always a dicey proposition. Additionally, the number of mbox POP3 servers which Do Not Suck(R) is rather low right now. Timo finally introduced an mbox IMAP server which definitely Does Not Suck, notably it allows for multiple clients accessing the same mbox mailstore, something previously only offered by Cyrus and perhaps maildir ("perhaps" only because I do not use maildir). Not to mention, quite frankly, most mbox POP3 implementations suck pretty badly anyway. :P --Ian.

Yes, and I wouldn't have done it if it hadn't been so easy. I don't really encourage people to use it anyway, it's even disabled by default. If it has bugs, it doesn't affect the IMAP side. If people really need to run both IMAP and POP3 servers, it is simpler to use the same configuration for both, especially if the configuration isn't "standard" (eg. LDAP or SQL authentication, mailboxes in special locations, etc). All other major IMAP servers provide their own POP3 servers as well, if you haven't noticed :) > Donald Knuth said in a seminar that I attended that the best way to keep a > program free from bugs it to complete it. Finish off the project, work on > fixing bugs. That's Binc IMAP's philosophy. That's the ideal situation, and even possible if you keep the original goals. But there are IMAP extensions which may require large changes, new mail storage formats and ways to deliver mail into them, clustering, etc.

Sorry, I just got a bit disappointed after reading the the web page first. Your lines of code comparisions just seemed to imply that your server does everything that others would but with only a fraction of code. There was also something about Dovecot's design being too complex, so I thought you might have solved those problems more elegantly. When you write something from scratch, I think it's a good idea to design it so that it's superior to existing implementations in at least some ways, not just make a clone with slightly different coding style. If all you wanted was a clone with some changes (and better maintainer), forking the project would be much smaller job. Well, here's some design thoughts: Maildir implementation could be hidden behind a class to access it. That would keep the ugly details hidden from the rest of the code, as well as allow easily implementing other mail storages. Restricting yourself to only plaintext authentication doesn't sound very good plan. Separating the pre-login process from post-login process would probably be a good idea to keep their functionality completely separated. It would also be easier to audit the pre-login code if you knew exactly what there is. After logging in, you could just exec() the post-login process.

Someone wanted it so it'd be easy to run both POP3 and IMAP servers without having to configure them twice.

It includes full LDAP support now, can anyone test if it really works? It has worked with some of my tests, but I don't know too much about LDAP so I might have missed something important. The authentication problem in test1 and test2 is also fixed now.

Fixes several smaller bugs. Finally works with FreeBSD (tested with 4.7 and 5.0). I think there's still some problems with authentication failing sometimes due to memory/ipc corruption. I haven't seen those today, but I don't think I've fixed that either.. One behaviour change is that if default_mail_env isn't set and mbox format is detected (~/mail dir), /var/mail/user or /var/spool/mail/user is used as INBOX if found.

by Timo Sirainen 04 Feb '03

04 Feb '03

I think all of the reported bugs are again fixed in CVS, so I made a tarball of it. I'd like to hear if there's any problems with it. Here's the most important changes: v0.99.8 2003-02-xx Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND and UNSELECT extensions. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() (not really tested) - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - Next command after STARTTLS was ignored which left the connection stuck sometimes - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions

[dovecot] Recent messages
by Jaime Medrano 03 Feb '03

03 Feb '03

Dovecot seems to manage \Recent messages in a weird way. When a STATUS command is performed in a mailbox, then the \Recent flag of its messages disappear and latter STATUS commands report that there are no recent messagges. I don't know exactly the behavior of the RFC. But other imap servers (UW-imapd, Netscape Messenger...) report the same number of recent messages when two STATUS commands are performed together. -- Jaime.

[dovecot] Unable to Log in on FreeBSD server?
by Mark 21 Jan '03

21 Jan '03

Hello! I recently compiled dovecot 0.99.7 on a FreeBSD 4.3 server, and have been having problems with logging in and password authentication. a. I can't seem to get it to compile MD5 support -- it only seems to support plain, plain-file, and pam. b. Whenever I try to log in, I always get something along the following lines in /var/log/messages .... Jan 16 17:52:15 akira imap-login: close(master) failed: Bad file descriptor Jan 16 17:55:33 akira imap-auth: Userinfo pam doesn't support DIGEST-MD5 method Jan 16 18:08:28 akira imap-master: Login process died too early - shutting down (I also included one about MD5 in there too! :-)) Basically, the imap-login process is dying every time I try to do a login from a remote machine (I've tried Evolution and Outlook Express ....) I've tried telling it to use port 143 and port 993 (where it correctly generates a warning about a certificate that it can't verify, since i created that certificate with mkcert.sh ) Is there something I haven't configured correctly? The only things I've changed in dovecot.conf are: Any suggestions? Thanks, Marc.

[dovecot] mbox & Maildir

Hi, Is it possible for a client to read both mbox and Maildir formats from one server running dovecot? Without changing default_mail_env in dovecot.conf, Maildir folders are working ... they're located in ~/Maildir. No /var/mail/username exists. I have mbox format folders in ~/mail and have been trying to get pine to find them by adding pine folder collections. I always end up back in ~/Maildir, though. Thanks, Jim

[dovecot] 0.99.6rc3

13 Jan '03

Well, "release candidate" wasn't really right name for last two versions. Maybe not for this one either, it has a few changes that could potentially break things badly (new hash table code especially). Anyway, seems to work with me. If I don't see any problems with it for a few days it'll be the final. The really great news is that we support threading. A lot of people have not used Dovecot simply because it couldn't be used for webmails. Hmm. What's the next most important feature? .. Better mbox support? Shared folders? Quota? LDAP/MySQL/etc. authentication? Here's the change summary: v0.99.6 2003-01-xx Timo Sirainen <tss(a)iki.fi> + THREAD=REFERENCES extension support.
