[Dovecot] dovecot: child 1690 (auth-worker) killed with signal 11
by Thomas Zajic 10 Aug '07

10 Aug '07

Hi there, I've been seeing this for quite a while now, but only today finally got off my lazy you-know-what and did a backtrace. Here's the requested info as per http://dovecot.org/bugreport.html: * Dovecot version [root@airframe]:~# dovecot --version 1.0.3 * Operating system or Linux distribution name Slackware 10.2, both kernel 2.6.21.3 and dovecot self-compiled * CPU architecture (x86 or something else?) x86 (AMD Athlon XP 3200+) * Filesystem you used (especially if you use NFS or not) ext3, local (no NFS) * Some kind of description of what you were doing and with what IMAP client. Thunderbird 2.0.0.4 (also happened with earlier versions) mail-notification-4.1 (" " " " " ) * If the problem can be reproduced, it helps a lot if you can tell how. Happens in almost regular intervals, not sure when exactly though. Usually when doing something in TB again (deleting or moving mails) after it has been sitting idling for a while. From the log files going back to July 22nd: [root@airframe]:~# grep "dovecot: child .* (auth-worker) killed with signal 11" /var/log/maillog* | wc -l 258 TB is configured to use TLS and secure authentication, use IDLE, and 5 cached server connections.

[Dovecot] Version 1.1 Alpha 2 Various Stuff
by Jerry Yeager 09 Aug '07

09 Aug '07

Some preamble information… OS X 10.4.10 (all updates) Power Mac Dual G5, 2.0 Postfix with Dovecot SASL, Dovecot LDA, Dovecot imaps (openssl) Mail clients Apple Mail v 2.1 SquirrelMail v 1.4.10a Thunderbird v 2.0.0.6 Mulberry v 4.06 For various versions of Dovecot, from 0.9m up through 1.0.3 things went well, no memorable big problems, with one exception: Mulberry v 4.0.8 would/will not work; i.e. it refuse(d) to connect saying it could not start SSL to begin the connection. Dropped back to version 4.0.6. I switched to version 1.1 alpha 2 (compile and configuration information is attached at the end of this message) 1) Started up Apple mail. Mail boxes disappeared in Apple Mail's list, except for the main Inbox mail box. Fixed by setting mailbox_list_index_disable = yes in the Dovecot.conf file, restarted both Dovecot and Mail, all the mailboxes reappeared and worked correctly. 2) Started up Squirrel Mail using several different browsers. No problems. 3) Started up Thunderbird. No problems. 4) Started up Mulberry. It partially connected, but stopped with the error saying that it had hit the limit for maximum connections. Mail logs show: dovecot: imap-login: Maximum number of connections exceeded: user=<username>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.50, TLS I tried increasing the various limits in the Dovecot.conf file up through a maximum limit of 2048 connections, to no avail. Mulberry will initially connect to several of the mailboxes, but will stop without getting all of them and will throw up the 'over the connection limit' error and will then show you a dialog box that asks you to log-in. Attempting to doing so returns a fatal error 54. I have not tried Mulberry's version 4.0.8. 5) Mail logs had this message suddenly begin appearing: auth-worker(default): pam(username,192.168.1.1): pam_authenticate() failed: Authentication failure Fixed by completely commenting PAM authentication section out; It was: passdb pam { # [blocking=yes] [session=yes] [setcred=yes] # [cache_key=<key>] [<service name>] # ... essentially a placeholder section, since everything inside is commented out # # } now is: #passdb pam { # # ... even the outer block is commented out # #} The error has now disappeared from the logs.

[Dovecot] Crash with 1.1alpha2 when lazy_expunge is enabled?
by Rich at Whidbey Telecom 09 Aug '07

09 Aug '07

I'm seeing a crash in 1.1alpha2 when trying to expunge a folder when "lazy_expunge" is enabled: namespace private { separator = . prefix = .EXPUNGED/ location = maildir:/mailstore/%u/Expunged hidden = yes } ... lazy_expunge = .EXPUNGED/ .EXPUNGED/ .EXPUNGED/ Commenting out "lazy_expunge" prevents the crash and mail is expunged. It happens with and without ACL's. Attached is the log output. The messages never actually get moved to the "Expunged" directory, but there is a "temp" file created each time: /mailstore/testuser/Expunged/ drwx------ 6 testuser users 4096 Aug 9 11:39 . drwxr-xr-x 4 testuser users 4096 Aug 9 10:59 .. drwx------ 2 testuser users 4096 Aug 9 10:59 cur -rw------- 1 testuser users 24 Aug 9 11:39 dovecot.list.index.log -rw------- 1 testuser users 28 Aug 9 11:39 dovecot.list.index.uidmap drwx------ 5 testuser users 4096 Aug 9 11:02 .Junk -rw------- 1 testuser users 0 Aug 9 10:59 maildirfolder drwx------ 2 testuser users 4096 Aug 9 10:59 new -rw------- 1 testuser users 0 Aug 9 11:04 temp.mail4.whidbey.net.8596.7b344a891b2c6691 -rw------- 1 testuser users 0 Aug 9 11:32 temp.mail4.whidbey.net.8761.bfe04f5457e4ba7e -rw------- 1 testuser users 0 Aug 9 11:33 temp.mail4.whidbey.net.8765.44e803d87275348a -rw------- 1 testuser users 0 Aug 9 11:37 temp.mail4.whidbey.net.9031.f4a972591af59e05 -rw------- 1 testuser users 0 Aug 9 11:39 temp.mail4.whidbey.net.9125.d67b160254a01631 drwx------ 2 testuser users 4096 Aug 9 10:59 tmp Lazy expunge works on our production 1.0.0 systems.

[Dovecot] UW-IMAP style mbox snarfing from /var/mail/ to ~/mbox
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/patches/mbox-snarf-plugin.c Also committed to CVS HEAD. Usage: mail_location = mbox:~/mail:INBOX=/var/mail/%u protocol imap { mail_plugins = mbox_snarf } protocol pop3 { mail_plugins = mbox_snarf } plugin { mbox_snarf = ~/mbox } If ~/mbox doesn't exist, nothing special is done. If ~/mbox exists, it's treated as INBOX and mails are moved from /var/mail/%u whenever the mailbox is synchronized. If all the messages couldn't be copied, for example because of out of quota, then none of the messages are copied. I suppose that could be a problem. It might be possible to fix that by changing: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) { ret = -1; break; } } to just: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) break; } But I'm not sure about that. Try and tell me. :)

Debugging information would have been really useful, but I did fix one bug and added some more asserts: http://hg.dovecot.org/dovecot-1.0/rev/bd113e9fe67b If it still wasn't fixed, maybe with this change it gives another assert.

[Dovecot] Outlook 2000/2003 frequent disconnect issue
by Jeff Ramsey 09 Aug '07

09 Aug '07

I have been using Dovecot for an IMAP server for a few years now, with no hitch. Even using Outlook 2K/2K3 as a client. Yesterday, I had a user experience the 'Negative UIDs' issue spoken of here: http://wiki.dovecot.org/Clients/NegativeUIDs I performed all of the steps mentioned in this article, and it seemed like it would work properly the first time the user checked their email, and then after that, they would get this error again. I checked to see what the latest stable version of Dovecot was, and decided to upgrade. I was at 0.99.11-8 and the latest stable rpm for my distro was 1.0.2-2. The upgrade went fine. Or so I thought. I am now getting the following message on all Outlook Clients: "Your IMAP Server closed the connection....this can occur if the connection is idle for too long" I have scoured the Internet for this error and have come up with many suggestions, none of which have worked. I have increased Outlook's timeout period to the full 10 minutes, and I have disabled SELinux. None of this seems to have worked. Is there anyone out there who has actually had this issue and resolved it? Can you please help?

[Dovecot] Database server failure causes endless loop
by Andy Shellam 09 Aug '07

09 Aug '07

Hi, I've just started setting up Dovecot 1.0.1, and made an error in my configuration, which I think has found a potential problem in Dovecot. I'm using PostgreSQL authentication, and set the database host to "localhost", which PostgreSQL doesn't listen on, so libpq is throwing the standard "is the server running?" message. The problem, however, is Dovecot isn't seeming to understand this, and is endlessly looping, trying to query it every 5 seconds. My client (telnet during testing) is simply sitting there waiting for a response, which it's never going to get. After about 5 minutes, Dovecot killed the connection, saying "* BYE Disconnected for inactivity." If this was from an IMAP client, I'm guessing the client would time-out after so long when it doesn't get a response back. Wouldn't it be more sensible for Dovecot to try PostgreSQL, say, 3 times. If unsuccessful, send the client an "internal server error" or something similar? Otherwise if the database server failed, and the client tries to connect, it'd be waiting for at least a minute (or whatever the standard time-out interval is) before failing, whereas it'd be better to see almost instantly if the server's down. Regards, Andy.

[Dovecot] Moving mboxes around
by tomas＠tuxteam.de 09 Aug '07

09 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dovecot gurus, I have a couple of questions for which I haven't found answers in the docs (which may be well more a limitation of my capabilities than anything else). Here they go: - Is it OK to move mailboxes around from under Dovecot? Case in point: I'm using procmail to pass incoming mail through bogofilter (the standard recipe mentioned in their manpage, which more or less funnels spam into a "spam" mailbox, unsure into an "unsure" and non-spam into "inbox"). From time to time I'd like to clear the spam and unsure mailboxes, using logrotate. Dovecot seems to cope with it. Am I tempting my luck? - Is there a way to tell an external application when mail has been moved by a client? Again: dovecot+bogofilter: from time to time a client checks incoming, unsure and sometimes spam and decides to move --say-- a mail from unsure to spam (deciding it's spam, after all) or similar. This is of course important for the training of bogofilter, so I'd like to trigger a backend action. I see basically two possibilities: - create two more mailboxes, say "spam-indeed" and "ham-indeed". User is told to move mail into these. Ham-indeed gets re-funneled to inbox (or something like that). Manual and error prone. - Use the mail_log plugin (seems more attractive). I still have (distro-provided) dovecot 0.99.14, but this would be a good reason to upgrade. (I still don't see where I get the source mailbox in the mail_log messages from, but that's details now). You get the idea, I think. Anyway, I am interested in any ways to combine dovecot and bogofilter in the backend in a way that I can route user feedback to the filter without putting too much burden on the user. Ideas? Thanks - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGtuS4Bcgs9XrR2kYRAkiXAJoDJYZC8DYIxFqCw+HEIn0CCNssQwCfaZjh z533XFMH36c4Lemv/+gSn9A= =s87z -----END PGP SIGNATURE-----

[Dovecot] passdb/userdb restart
by Thomas Hummel 09 Aug '07

09 Aug '07

Hello Timo, I've noticed that when slapd which I'm using as the passdb and the prefetched userdb is restarted I have to restart dovecot. As a matter of fact, if I don't, I get the following error : -- Jul 2 16:38:39 xxxx dovecot: imap-login: Internal login failure: user=<xxxx>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS Jul 2 16:38:46 xxxx dovecot: auth(default): prefetch(xxx,xxx.xxx.xxx.xxx): passdb didn't return userdb entries Jul 2 16:38:46 xxxx dovecot: auth(default): userdb(xxx,xxx.xxx.xxx.xxx): user not found from userdb -- I'm using dovecot-1.0.1 on FreeBSD 6.2-STABLE with openldap-server-2.3.35_1 (bdb backend). Would some cache-related parameters allow to fix that or will restarting dovecot be always mandatory after an ldap restart ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] 1.1.alpha2 error in logs
by Mike Cisar 09 Aug '07

09 Aug '07

Did a quick-n-dirty install of 1.1.alpha2 on a Fedora Core 6 server... am getting the following message in the maillog, though there seems to be no problem accessing mail. Error seems to be consistent for all users. Running 1.0.3 on the system previously.

[Dovecot] lda: vacation auto-reply for a virtual address
by martin f krafft 09 Aug '07

09 Aug '07

Hi, I am using Dovecot to manage a complex virtual mailbox setup. It's all working splendidly, thanks to the Dovecot LDA. This morning, however, I needed to create a vacation-style autoreply for one of the virtual addresses. I made use of cmusieve, authored a little sieve script, and had it working in no time... until I discovered how limited sieve's vacation module is. Most importantly: it's hardcoded to use the Return-Path of a message, but in this very case, I need to actually use the address in the from header. So I had to give up on sieve and am now looking for another solution, but without much success. Given that mail is delivered by the Dovecot LDA, is there any way to make deliver pass it off to e.g. procmail in such a way that $HOME is set to /srv/vmail/domain.org/localpart, so that procmail can find the .procmailrc? Cheers, -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck "we are trapped in the belly of this horrible machine, and the machine is bleeding to death." -- godspeed you black emperor! spamtraps: madduck.bogus(a)madduck.net

[Dovecot] LDAP and (py|cmu)sieve
by Thibault VINCENT 09 Aug '07

09 Aug '07

Hello, Before asking help, i would like thank Timo for this awesome server, it's lite, fast, and has good features. I've read the Wiki, tutorials, and tried various configurations to get the result I expect. My company is running a dovecot 1.0.0 server set up with an LDAP directory, mails are delivered to /var/spool/imap and users do not have a real unix home directory on this system. During my internship, I've installed a sieve server (pysieved) that is working with dovecot. But I encountered a problem with the LDAP setup. Pysieved is using dovecot's auth and client sockets to authenticate the user and get it's home directory where it will store sieve scripts, this home directory is also actually used by cmusieve. With our setup, users do not have /home directories on the mail server but the homeDirectory LDAP attribute is used by other services and cannot be modified for dovecot. I know we have the option to create a new attribute, set it to something like /var/spool/imap/<user> for every mail users, and use this new attribute name in dovecot-ldap.conf with the user_db statement. This is actually working on a test environnement, but we wish we could do it without any modification on the LDAP directory. The very precise question is : How can I tell dovecot to compute the « home » path from the login name when using LDAP userdb ? By example, if a user has login name "jdoe", dovecot will authenticate him against the LDAP directory but won't get the home path from it. Instead, it will use the same mail_location path (if possible) or something similar, like /var/spool/imap/%1u/%u . Can I do this without any modification of the source code of both dovecot and pysieved ? Thank you, -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B

[Dovecot] HP-UX troubles
by Matthias Luehr 09 Aug '07

09 Aug '07

Hi there, I got dovecot compiled and running on HP-UX 11.23. It's using LDAPUX and PAM for authentication. So far, it works. But after logging in the connection is closed immediately. It looks like this: telnet <ip> 143 Connected to ... Escape character is '^]'. * OK Dovecot ready. a01 login <user> <pass> Connection closed by foreign host. The dovecot log says: Error: imap-login: fd_send(7) failed: Bad file number Error: child 22629 (login) returned error 89 As far as I can see, the problem seems to reside in dovecot's fdpass.c... dovecot version: 1.0.3 gcc version: 2.9 Any ideas or solutions? Thanks in advance, Matthias

[Dovecot] UIDL match from 0.99.13 to 1.0-1.2
by Daniel Davidson 09 Aug '07

09 Aug '07

I am moving from and old FC2 system to a new RHEL5 system and am having trouble getting the UIDLs to move over right, mainly the UID. I copy over the mailbox, and see the x-uid in the message is what it was on the old server, but when I telnet in to check pop, it rewrites x-uid in the message to something new, causing old messages to get downloaded again, which is not what we want I have tried setting pop3_reuse_xuidl to yes, but that did not change anything, probably because that is the wrong header (I do not have x-uidl, but I do have x-uid). I do have pop3_uidl_format set to %v.%u for compatibility. On the old system the first five are: +OK Logged in. uidl +OK 1 1095087961.3092736 2 1095087961.3092737 3 1095087961.3092738 4 1095087961.3092739 5 1095087961.3092740 On the new system the first five are: +OK Logged in. uidl +OK 1 1095087961.3093018 2 1095087961.3093155 3 1095087961.3093156 4 1095087961.3093157 5 1095087961.3093158 Any help would be appreciated, I do not understand how it is generating the UID portion.

[Dovecot] Userdb and home directories
by Mike Brudenell 09 Aug '07

09 Aug '07

Greetings - I've just discovered an oddity I didn't know I had... We have two NetApp filers: one serves people's home directories; the other their message store and control files filestores. At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. However in practice Dovecot DOES appear to be using it: it is trying to chdir() to my home directory when I login, finds it can't at the moment (because of a problem giving "Permission denied"), and closes the connection. I've read the pages on home directories and the userdb on the Wiki and it advises that having a home directory is beneficial. I'm happy to create a subdirectory for this within a user's control files directory, but do NOT want it on our normal filestore: we can't have mail inaccessible because a user's home directory is inaccessible because the other filer is out of action. We use shadow for the passdb and passwd for the userdb (see dovecot - n output below). I'm trying to work out how to override the home directory returned from NIS. Ultimately I'd like to use this template: /mailstore/control/%1Ln/%Ln/home but for the time being while I'm trying to work out how to do it have my own area hard-coded in (as it's only me logging in to the test system): /mailstore/control/p/pmb1/home I'm specifying this with the "args" directive in the userdb section as follows: args = home=/mailstore/control/p/pmb1/home but it isn't being picked up. What am I doing wrong, please? (We want to continue using uids and gids etc from NIS so I don't think using the static userdb is the right thing to do?)

[Dovecot] dovecot-sieve vacation changes
by pod 09 Aug '07

09 Aug '07

I'd like to put forward the following patch for dovecot-sieve. Essentially this just merges in some changes made in CMU sieve 2.3.8 and as such brings the behaviour more in line with RFC 3834 "Recommendations for Automatic Responses to Electronic Mail": - fixes erroneous sender "-request" substring match - checks for existence of a selection of list-* headers - expands "named-as-recipient" header checks to "Resent-To", "Resent-CC" and "Resent-BCC" fields. Note that the appended patch also includes a fix for some missing parentheses in the "resent-to" test which resulted in some extra work being done but was otherwise harmless. The fix has been sent to <cyrus-bugs+(a)andrew.cmu.edu> - prefixes subject in response with "Auto: " rather than (non-expanding) "Re: " I also, mostly for kicks, attach two sieve-like scripts that attempt to encapsulate the when-not-to-respond logic as implemented (if the patch were to be applied) and as advised by RFC 3834 respectively. I wrote these as an exercise to help me gain a better understanding of sieve and the CMU implementation. I'm not sure they are otherwise useful.

[Dovecot] NFS rquota support
by Timo Sirainen 09 Aug '07

09 Aug '07

For v1.1, probably applies to v1.0 code pretty easily too: http://hg.dovecot.org/dovecot/rev/078d9dde99c8 The other rquota patches had authunix_create_default() call. Is this needed/useful? The client is now always created+destroyed for each quota lookup. I'd think it would be faster if it was created only once, but does it then break something? If the above isn't done, clnt_create() could be replaced with clntudp_create() and have the struct sockaddr_in cached. Patches welcome. :)

[Dovecot] Shared folder hierarchies, multiple groups
by Benjamin R. Haskell 09 Aug '07

09 Aug '07

Hi, I'm trying to set up two shared folder hierarchies on my Dovecot installation for two groups of employees, all of whom should only have access to their own hierarchy. Any employee should be able to create sub-folders and generally have full access to the hierarchy. My initial setup was to create two public namespaces, Shared-One and Shared-Two. Each is a Maildir under /var/mail. The actual shared folders seem to be working fine in terms of adding and accessing folders and messages, and there are no problems at all for the 'admin' user, who belongs to both the shared1 and shared2 Unix groups. The problem is for other users, where trying to (IMAP-) LIST folders fails. (sanitized) IMAP session log: ('user2' is in group shared2) * OK Dovecot ready. A LOGIN user2 pass A OK Logged in. B LIST "" "%" * LIST (\Noselect \HasChildren) "/" "Shared-One" B NO Internal error occurred. Refer to server log for more information. [2007-08-02 09:01:23] In the mail logs I find: dovecot: IMAP(user2): stat(/var/mail/Shared-One/cur) failed: Permission denied Relevant permissions: 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One/cur 0660/-rw-rw---- shared1 shared1 /var/mail/Shared-One/dovecot-shared And similarly for Shared-Two. (replace shared1 with shared2 everywhere) Among other things, I've read: http://wiki.dovecot.org/SharedMailboxes http://wiki.dovecot.org/ACL http://wiki.dovecot.org/MainConfig http://wiki.dovecot.org/Namespaces I don't want to use vfile ACL's (I think) because I want users to be able to create subfolders at will, and I don't want to have to add a dovecot-acl file per-folder. (Is there a way to set global defaults on a global basis? [not per-folder]) I also think there would be a problem with the hierarchies being similar. (e.g. both have a 'Projects' sub-folder, but there's a pretty clear WARNING on the wiki about mailbox name conflicts.) I can't use symlinked Maildirs, because new subfolders get created under ~user/Maildir/. (Want them under /var/mail/Shared-X/) I can't use hidden namespaces, because employees use Outlook (uggh), and I couldn't figure out how to "find" the namespace when it was hidden. (That seemed like the closest thing to a solution - it solved the LIST problem.) Ideally, Shared-Two wouldn't even be visible to members of Shared-One, and vice versa. But, that's at least an acceptable "problem" I could live with. Any suggestions? Thanks, Ben

Hi. I'm using SMTP auth with Exim authenticating against Dovecot's auth socket.

[Dovecot] Authentication problem - or is it?
by Anne Wilson 09 Aug '07

09 Aug '07

My old server ran v.0.99, and this is the first time I've tried to get v.1 running. When I try to test it with telnet I see telnet localhost 143 Trying 127.0.0.1... Connected to david.lydgate.lan (127.0.0.1). Escape character is '^]'. * OK Dovecot ready. x login anne xxxxxx x OK Logged in. Connection closed by foreign host. I assumed it was an authentication problem (I want to use /etc/passwd as the authentication file) but it does say that I managed to log in. If so, what could be causing it to close immediately? Anne

[Dovecot] v1.1.alpha2 released
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz.sig Hopefully the next release can be v1.1.beta1. I'm not aware of any major problems and I think I'm pretty much done with new features (except for dbox). The largest changes since alpha1: * Removed THREAD indexing. It's a bit buggy and I think there's a better chance of releasing a bugfree v1.1 soon if it's not included. I'll fix it after v1.1. * Removed THREAD=X-REFERENCES2 also because it wasn't as easy to implement with the old threading code. I might put this back though if there's enough interest. * PAM always works in blocking=yes mode now. If you have problems with memory leaks, change auth_worker_max_request_count setting. + Filesystem quota backend supports inode limits, group quota and RPC quota for NFS. + SEARCH and SORT finally compare all characters case-insensitively. We use i;unicode-casemap algorithm. + Config files support splitting values to multiple lines with \ + Winbind NTLM and GSS-SPNEGO mechanism patches by Dmitry Butskoy.

[Dovecot] Not seeing other folders with some clients

[Dovecot] BUG (and suggested fix) in maildir code
by Tom Vajzovic 08 Aug '07

08 Aug '07

Hi all I'm using dovecot 1.0.rc15 to serve a maildir by IMAP. I have an IMAP subdirectory called subscriptions. The messages are in maidir/.subscriptions/cur/ etc. Dovecot is renaming the directory .subscriptions/ to subscriptions/ This means that when my IMAP client requests this directory, it gets the message "no such directory", and dovecot also gives the error message: dovecot: IMAP(tcv): read() failed with subscription file /var/mail/maildir/tcv/subscriptions: Is a directory The two should be able to live happily side by side, with the subscriptions file called "subscriptions" and the maildir called ".subsciptions". The offending function is maildir_subscriptions_convert_099() in src/lib-storage/index/maildir/maildir-storage.c Can someone with developer access please change this so that rename() is not called if subscriptions is a directory. Thanks, Tom

[Dovecot] dovecot.conf an <TAB> chars
by Sascha Holzleiter 08 Aug '07

08 Aug '07

Hi, I just wanted to "beautify" my dovecot configuration file and as one of the first comments suggests whitespaces and <TAB> should be completly ignored but that doesn't seem to be the case, e.g.: postmaster_address<TAB>= some(a)address.de results in an configuration error as the postmaster_address is not set. Using just a space or replacing the <TAB> char with space chars resolves the problem. This is with dovecot version 1.0.3 on Debian and FreeBSD. Greetings, Sascha

[Dovecot] OpenBSD and too many open files
by Bryan Vyhmeister 07 Aug '07

07 Aug '07

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine. I just recently upgraded to dovecot 1.0.2 from ports and now I am having the same problems again. I moved kern.maxfiles for that class from 2048 up to 3404 and yet I still run into the error. When I do, I have to restart dovecot to get things running again. Output of: su -c dovecot root -c 'ulimit -a' time(cpu-seconds) unlimited file(blocks) unlimited coredump(blocks) unlimited data(kbytes) 1048576 stack(kbytes) 8192 lockedmem(kbytes) 634482 memory(kbytes) 1898080 nofiles(descriptors) 3404 processes 1044 sysctl kern.maxfiles gives: kern.maxfiles=3404 My main IMAP accounts reside on this server and I have somewhere in the 25000 range of stored messages. Could this be causing the issue? I only have maybe a dozen other users using this server right now but I am planning on putting 500 users on it soon. I added another heavy IMAP user shortly before these problems started but I don't know if that has anything to do with it or not. Likewise, I am not sure if the dovecot 1.0.2 upgrade had any effect either although it did coincide. Any ideas? Thank you. Bryan

[Dovecot] vfile ACL's
by Benjamin R. Haskell 07 Aug '07

07 Aug '07

(Sorry for the impatience. This was one of several questions in my email from yesterday. I thought I might have better luck being more direct.) Is there a way to set ACL's, using the vfile backend, on a truly global basis? or hierarchically (i.e. .Maildir.Sub inherits from .Maildir)? The wiki page says: "The default ACLs for mailboxes is to give owner all permissions and other users none. Mailboxes in public namespaces don't have owners, so by default no-one can access them." Is this configurable? Thanks, Ben

[Dovecot] dovecot + LDAP-SASL ?
by Hadmut Danisch 07 Aug '07

07 Aug '07

Hi, just a question: I know that dovecot supports SASL authentication and supports LDAP. Which means that dovecot performs the SASL methods itself and stores the plaintext secret on LDAP. But it is also possible to have the LDAP do the SASL work and dovecot just pass SASL messages through? Even when the LDAP server uses a proprietary SASL method not supported by dovecot? regards Hadmut

[Dovecot] Ideas for Webmail/OTP
by Frank Behrens 07 Aug '07

07 Aug '07

I want to discuss some problems/enhancements for dovecot in a webmail/otp setup. For access to an IMAP server like dovecot I see different client types: a) a "normal" MUA installed in a more or less trusted environment b) remote access via "webmail" from untrusted environments For a) I see with dovecot and other IMAP servers no problems, tricky is the setup for b). If you use a webmail client in an untrusted environment the risk is high, that keyloggers and other malware steal your password. One easy solution is to use One-Time-Passwords (OTP). The otp setup for interactive logins (e.g. ssh) is easy, but until now I did not find any easy to use solution for webmail. The main problems I see - In most cases a webmail client does not hold a persistent connection to the IMAP server, but makes a login for every request. - The webmail clients are not prepared to display the otp password challenge to the user. When we say "otp" with IMAP we further have to distinguish a) the OTP SASL authentication mechanism b) OTP configured by PAM. I believe a) is implemented in new dovecot 1.1 version, but I prefer b), because - it works with many clients without special client support - all authentication setup is central in the os. All above described problems are not specially linked to dovecot, but I believe with dovecot there is an easy solution to solve them. :-) Solution 1: When PAM is configured for IMAP the user can use a one-time-password in the same way as before. The problem is, that the user must know the sequence number for the password (otp challenge), so we need a way to display it. The PAM module supplies the otp challenge in the conversation function, but the challenge is not processed by the IMAP server. My proposal: The IMAP server stores the challenge from the conversation function and includes it in the LOGIN response, when the login was not successful. So a user can try a login with a wrong dummy password and get knowlegdge about the current otp sequence. The webmail server should be extended in a way, that it displays the complete IMAP error message, when a login fails. Solution 2: Webmail clients do not use persistent connections in most cases. A OTP login needs different passwords for every displayed web page. My proposal: Use dovecot's login cache and do not ask the os for every login. :-) Solution 3: When we configure PAM we can restrict/allow it's use depending on IP address of client. Unfortunately with a webmail client the IMAP client is always the the webserver. It should be possible, that the webserver forwards the client IP address to the IMAP server. Furthermore to use dovecot's login cache as described above in a safe manner, the IP address should be compared, too. My proposal: Create a new IMAP command "XSETREMOTEIP". With this IMAP extension a client can set the real IP address of remote client. The access to this command is restricted to the webserver with a new configuration parameter "trusted clients", which holds an IP address with mask. I ask to discuss these solutions. It seems to work, I'm making the first tests now. I have patches for dovecot and squirrelmail, but they are very "quick and dirty". They show a possible solution, but not a clean implementation. Do you believe, that we can build a good webmail system this way, or do you have better solutions?

[Dovecot] [PATCH] Split sql drivers from lib-sql to plugins
by Tomas Janousek 07 Aug '07

07 Aug '07

Hi, in order to solve rhbz#170960 [1], I split the sql drivers to plugins so that they are loaded dynamically and can be split to separate packages. [1] https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170960 The patches are here: [2] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-1.0-split.patch [3] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-trunk-split.patch (mv src/lib-sql/driver-mysql.c src/plugins/sql-mysql/, etc., afterwards) I'd like to ask for your comments and whether it's ok for inclusion or at least ok to use in the Fedora package. Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] cache questions
by Daniel Watts 06 Aug '07

06 Aug '07

Hi Guys, We have: auth_cache_size = 2048 #Kb auth_cache_ttl = 900 #life of the cache Seems to work well (though haven't tried looking at stats). Only problem is that every so often, one of our new users tries to log in quickly before the account is marked (in a db) as 'active'. They use the right password but the sql query fails because the active flag is not yet set. This results in their trying to log in and failing for 15 minutes (900 seconds) until the cache clears. Is this dovecot caching negative results? Is this a good idea and can it be disabled? Some more questions: 1. Is the expire time on a per-login basis or for the entire cache? If someone logs in 14 minutes after the last expiry is their data cached for just 1 minute? 2. If it is per-login, is the time reset after every hit? If someone is using webmail and hitting the cache every 5 minutes, will the cache keep the information? 3. How does the cache size relate to number of distinct logins? Roughly how many auth datasets cached per 1MB of cache? Thanks! Daniel tg3 dovecot # dovecot --version 1.0.rc27 p.s. please CC my email so I know when this has been replied to. I will respond to group!

[Dovecot] Benchmark: Appending 250k messages
by Timo Sirainen 06 Aug '07

06 Aug '07

I just changed Dovecot v1.1 code to work much more nicely when appending new messages to large mailboxes. Dovecot hg (cydir format, fsync_disable=yes): ./imaptest secs=1 ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2322 1/ 1 0 0 1998 1/ 1 0 0 2293 1/ 1 0 0 2009 1/ 1 0 0 1789 1/ 1 0 0 1245 1/ 1 0 0 43 1/ 1 0 0 32 1/ 1 0 0 881 1/ 1 0 0 2137 1/ 1 .. 0 0 704 1/ 1 0 0 771 1/ 1 0 0 388 1/ 1 0 0 831 1/ 1 0 0 572 1/ 1 0 0 766 1/ 1 Totals: 1 1 251397 Averaging 837/sec. The append speed jumps around quite a lot. Typically it's around 800-1000/sec, but it jumps between 0-500/sec also quite often. I'm not sure why that is. Cyrus v2.3.8 (fsync and fdatasync calls disabled from code): ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2587 1/ 1 0 0 1907 1/ 1 0 0 1597 1/ 1 0 0 1260 1/ 1 0 0 1220 1/ 1 0 0 1151 1/ 1 0 0 1068 1/ 1 .. 0 0 121 1/ 1 0 0 127 1/ 1 0 0 128 1/ 1 0 0 126 1/ 1 Totals: 1 1 79613 Averaging 265/sec. The speed slows down pretty consistently, there's no jumping like with Dovecot.

[Dovecot] Disable IMAP for certain users, but not Webmailer
by FORMER 03 | Baltasar Cevc 06 Aug '07

06 Aug '07

Hi everybody, I'm planning to set up our new mail system using the Dovecot mailbox server. It mostly works fine yet (it's quite straigt forward to set up, I'd say), but there's a thing I haven't been able to find out yet. We provide POP3 access for all users, but want to restrict IMAP access to some of them (because IMAP users tend to leave more messages on the server, thus increasing storage needs). I used to do it by providing two services. One provided the public imap and checked a database flag during authentication, the other just provided IMAP on localhost and did not check the "allowed to use IMAP" flag. What I've found for Dovecot is http://wiki.dovecot.org/Authentication/RestrictAccess While this allows me to provide full POP3 to everybody and in the same time restricting IMAP, I don't see a possibility Is there any possibility to achieve what I need without having two completely separated instances of Dovecot running? I'd appreciate any hints, pointers to documents etc. Thanx, Baltasar -- _____ FORMER 03 GmbH _____ infanteriestra§e 19 haus 6 eg _____ 80797 muenchen _____ baltasar.cevc(a)former03.de _____ www.former03.de _____ fon 089.322112.29 _____ fax 089.322112.11 _____ mobil 0178.691.2233 _____ geschftsfhrer _____ sebastian fiedler _____ gert zellentin _____ handelsregister _____ HRB Mnchen 148468 _____ steuer _____ ust.-id DE 2291076876

[Dovecot] dovecot.index.cache weirdness
by Tan Shao Yi 06 Aug '07

06 Aug '07

Hi Timo, Just a quick check, may I know if the following output of idxview is normal? (see bottom of e-mail) I am running dovecot-1.0.3 on a Solaris 10 SPARC box. Deleting dovecot.index.cache does not seem to help for this user; it keeps getting regenerated with these same lines. I seems that I have to set mmap_disable=yes on this box to have a "clean-looking" dovecot.index.cache. Is it mmap related? Or it just happens to be a coincidence? Cheers, Tan Shao Yi /usr/local/libexec/dovecot/idxview dovecot.index dovecot.index.cache (... normal looking stuff ...)
