[Dovecot] Bug in Deliver v1.2

[Dovecot] Config rewrite for v1.3
by Timo Sirainen 02 Feb '09

02 Feb '09

Still broken, but I committed the current changes to http://hg.dovecot.org/dovecot-config-rewrite/ The idea is something like: - src/config/ contains a doveconf binary which can be used to dump the current configuration. It's the only binary that reads dovecot.conf directly. Currently the code is kind of ugly because I wanted it to be able to parse the existing v1.2 dovecot.conf which required some kludging around. Perhaps in v2.0 the dovecot.conf could have larger changes and these kludges could be removed. - master currently executes doveconf 3 times: for default settings, for imap settings, for pop3 settings. The result is saved into an array of KEY=value pairs in an array. Eventually they're still sent to child processes via environment. This sending via environment is again mainly for backwards compatibility with post-login scripts. Although they are useful there, so I'm not sure if it should be kept that way. Although post-login scripting doesn't really work anymore with Apple's multiple-connections-per-mail-process code, so perhaps that needs some rethinking in any case.. - deliver also currently forks and executes doveconf. I hate this. But I don't like the alternative of having a libconfig that deliver could use to read the configuration inside the binary as is done now, because then it's not as easy anymore to update the doveconf binary (or replace it entirely). But I'm thinking about making doveconf a long running process and deliver could ask configuration from it via UNIX socket if it's running and fallback to forking doveconf. The last possibility would be not to fork, but instead just have doveconf exec() deliver, so either something like "doveconf -e deliver -deliver-params" or if calling deliver directly it could exec() doveconf which would then exec() deliver back. Hmm. Perhaps this is actually better than forking? - %variable expansion is somewhat broken with imap/pop3, but works with deliver. The annoying thing about this is that %vars from doveconf should be expanded, but if userdb returns anything containing %vars they shouldn't be (because e.g. home directory could contain %). So either master should expand everything internally or it should somehow tell child processes about what to expand and what not. It can't really expand everything because it doesn't know all the settings that should be expanded. So that only leaves the possibility of telling child process what to expand. One possibility is to prefix each environment with e.g. 0 or 1 specifying if it should be expanded. This would break all existing postlogin scripts and in general would make it kind of ugly. Another possibility would be to have an environment that lists the settings that shouldn't be expanded. Perhaps that would work better, although if postlogin script changes/adds environments they'd also potentially have to modify that environment too. - Plugins will probably have to keep using something similar to getenv() to get their settings. It would be possible to have them use the nice new pre-filled settings structures, but that would require configuration changes. For example instead of quota=.. quota2=.. you'd have two quota {} blocks. Probably better to leave that change to v2.0. - I'm not entirely sure where all the setting verifications should go. Having them done by master when starting up is nice because it can give error messages immediately and write them to screen, instead of having to look them up from the log. Or when reloading configuration it can cancel it if the new configuration isn't ok. Maybe doveconf could do the checks. Maybe the verifications could go to all the different *settings.c files where they logically belong to, and then the build scripts would copy those functions to doveconf code where it could check all of them when the config is being read. The only annoying thing is that this then required doveconf to be run as root so that it can do all the access() etc. checks. But maybe that's not too bad.

[Dovecot] mbox to maildir batch conversion
by Mike Hobbs 02 Feb '09

02 Feb '09

Hello, I'm upgrading my mail server from UW to Dovecot and I'd like to convert from mbox to maildir. I've successfully convert myself and a few other users with the mb2md script. All is well. My question is, I have somewhere around 500 users and about 122gb of mail folders to convert (this does not include the inbox at /var/mail). mb2md needs to be run as each user to convert. Are there any programs or scripts out there that will allow me to convert everyone at the same time? I know there is a Dovecot plugin to convert mail, but we didn't want to use this option. I'm sure someone on this list was in the same situation as me, how did you handle a massive conversion? Any help or suggestions is much appreciated!

[Dovecot] managesieve/README sieve_storage doc confusion
by Steffen Kaiser 30 Jan '09

30 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, http://hg.rename-it.nl/dovecot-1.2-managesieve/file/tip/README contains the paragraphs (line 47): " mail_location = If, for some inobvious reason, the sieve_storage remains unset, the managesieve daemon uses the specification of the mail_location to find out where to store the sieve files. However, this is provided only for backwards compatibility and you should always use the sieve_storage setting in stead. Additionally, the ManageSieve service uses the following settings from the plugin section of the config file. These settings are the ones used by the Sieve plugin. sieve_dir = This specifies the path to the directory where the uploaded scripts are stored. Scripts are stored as separate files with extension .sieve, all other files are ignored when scripts are listed by a ManageSieve client. If this setting remains unspecified, the mail_location setting is used as explained above. " Because sieve_storage is not mentioned anywhere else in the document and because of this discussion: http://dovecot.markmail.org/message/kzjpwdhyqhdn53zd , I suspect that sieve_dir is the older naming of it.

Or was it you? Anyway, dovecot-auth doesn't know how many users are logged in so if the problem really is 21 *concurrent users* instead of n logins/ second, I find it highly unlikely that the problem is with authentication. My guess is that this has something to do with NFS. Perhaps start Dovecot with strace -tt -f dovecot and then when it's slowing down see what syscall it says is blocking.

[Dovecot] cram-md5 problem
by Richard Stockton 30 Jan '09

30 Jan '09

I just updated to dovecot 1.1.10 from 1.1.2 and now anyone using cram-md5 can't get authenticated. I am using mysql for passwords (in plain text) and home directories. Per some googling I tried to set (in /usr/local/etc/dovecot.conf): # SQL database userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } but that didn't help. And in any case people NOT using cram-md5 can authenticate just fine, both before and after I made that change. This worked "out of the box" under 1.1.2, but is broken now. Any ideas appreciated. Thanks. - Richard

[Dovecot] Killing Dovect, an unpleasant surprise
by Stewart Dean 30 Jan '09

30 Jan '09

When it came time to upgrade DC or replace the certificate, I would find the root instance of dovecot and do a kill -7 of it. Within 20-30 seconds, all the hundreds of DC related processes would go away, I would swap the executable or certificate/key and restart DC. Very clean and quick. Surprise. After switching from 1.0.15 to 1.1.8 and doing the kill, I found that all the imap-login instances had been inherited by the root (1) process and did not go away. Yikes! An Unpleasant Surprise. So instead of being down for a minute, I was out for a much more noticeable 5-7 minutes, while I QUICK did an awk of the ps list to give me the pids and then xarg killed them. My boss asked me if this was a pink slip notice. :( Is this The Way Things Will Be? Is there a new way to kill everything DC related quickly and cleanly? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035 "Resolve then, that on this very ground, with small flags waving and tinny blasts on tiny trumpets, we shall meet the enemy, and not only may he be ours, he may be us." === From the introduction to the original Pogo Papers

[Dovecot] deliver and qmail
by Tim Traver 29 Jan '09

29 Jan '09

Hi all, ok, after looking at all of the posts that I've found, and trying numerous settings, I am a little stumped as to how to set up the deliver program with qmail to get everything correct. Ultimately, I really don't want to do a lookup of the home dir if I don't have to. I'd rather specify the stuff in the .qmail-user file for that particular user to avoid the extra step. In looking in the wiki, it says for users without a lookup to use HOME=/path/to/user/homedir deliver -f $FROM_ENVELOPE but I can't do that in the .qmail file, which would normally look something like this : |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -f ${SENDER:-<>} I would rather not do the master authentication socket as described for obvious reasons. is there a format in the .qmail file that I can use with deliver to achieve what I want??? Thanks, Tim.

[Dovecot] Confused about permissions needed for shared mailbox
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, let me re-state, hopefully in clearer terms, what I tried to described in a previous thread : With dovecot-1.1.8/Maildir/LDAP pass/userdb (prefetch), I'm trying to set up a Maildir ".box" shared in rw between 2 users in a "Public" namespace. I can't get it to work unless I chmod 777 everything, which obiously is not what I want. 1) am I correct thinking that the system_user userdb extra_field and unix permissions should be enough to achieve that and that ACLs is only if I want to fine tunes mailbox permissions ? 2) let's say that my public namespace prefix is Public/, that the .box/ maildir is in /path/to/public/.box and my 2 users belong to the doveshared unix group. I thought it would be enough to have drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public/.box -rwxrws--- 1 root doveshared 0 Jan 26 18:25 public/.box/dovecot-shared provided that my prefetch userdb returns system_user, as I think the following says in dovecot-ldap.conf : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and providedt that in LDAP shadowMax: 80 (whatever value). But this doesn't seem to work. By the way : Am I supposed to have a dovecot-shared file in public as well (that is not only in public/.box) ? 3) let's say I try ACLs with the same setup (anyone <all permissions> for starters) would pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user.title=userdb_acl_groups and title: group1,doveshared be a correct setup ? Do I need an dovecot-acl file only in .box or in public too ? My understanding is that my setup doesn't work because for some reason, dovecot doesn't see my users secondary groups or doesnt take them into account... Any thoughts which might help ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

The Maildir layout goes like this : /courriel/boites/foobar : Maildir of user foobar (nfs) /courriel/meta/foobar : control files of user foobar (nfs) /var/dovecot/indexes : indexes (locally stored) I created : /courriel/boites/doveshared/.box/ : the Maildir I want to share /courriel/boites/foobar/.box -> /courriel/boites/doveshared/.box (symlink) /courriel/boites/foobaz/.box -> /courriel/boites/doveshared/.box (symlink) the unix and LDAP group doveshared, so /etc/group holds : doveshared:*:<gid>:foobar,foobaz the permissions on the real Maildir are ok for that group : drwxrwx--- 3 root doveshared 4096 Jan 26 18:58 /courriel/boites/doveshared drwxrwx--- 5 root doveshared 4096 Jan 26 18:58 .box (in /courriel/boites) I made the userdb (prefetch) return the system_user extra_field (for now, I'm using an used LDAP attribute - I will create a new attribute in my schema later) : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and it seems to be actually returned : Jan 27 09:34:10 munster3 dovecot: auth(default): ldap(foobar,157.99.64.42): result: uid(user)=foobar uidNumber(userdb_uid)=xxx gidNumber(userdb_gid)=xxx homeDirectory(userdb_home)=/home1/xxx/foobar userPassword(password)=<hidden> shadowMax(userdb_system_user)=380 But I can't subscribe to the mailbox : stat(/courriel/boites/doveshared/.box/tmp) failed: Permission denied (euid=xxx egid=<primary gid>) as a matter of fact, the egid seems to be the primary gid. What am I missing ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] (imap) killed with signal 9 on Linux/OpenVZ VPS
by Adam Flott 28 Jan '09

28 Jan '09

I'm trying to get dovecot running on my VPS and the main imap process is receiving a SIGKILL from what I presume to be the Linux Kernel and/or OpenVZ. This happens after I login and my client(s) just sit their idling. The mailbox is empty. I'm not running out of memory. stracing the process doesn't show anything interesting... ... gettimeofday({1233024777, 844804}, {420, 0}) = 0 gettimeofday({1233024777, 844912}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 3, 10000) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ This is on a CentOS 5.2 VPS. I haven't changed much other than installing a few packages. I've also had this exact same problem on Debian 4.0 VPS (OpenVZ) under the same machine. Turning off SSL and logging in plain old IMAP didn't change anything. Under the Debian installation I tried the latest version of dovecot (1.1.8 or so), different I/O loop methods, turning them off, on, etc. The only other reference via Google I can find to this sort of problem is: http://www.dovecot.org/list/dovecot/2007-December/027440.html But that was with the login process, whereas mine is with the imap daemon. Any help is greatly appreciated.

[Dovecot] Old Thunderbird problem - need a fix
by Marc Perkel 28 Jan '09

28 Jan '09

I've been having a Dovecot/Thunderbird problem for about a year now and I need a fix. When I restart dovecot everything is fine but as the day progresses thing start deteriorating. When I empty my trash folder it doesn't empty. I get an indication that email has arrived in my inbox by the unread message count but can't access it. Messages arrive by appear to be empty. Folders that should be empty still have message counts showing. With all of the above problems - restarting dovecot make them all go away. I am doing something unusual in that I use Exim to directly deliver (maildir) to the inbox and other folders. And I have processes that take email out of certain folders (spam learning). Whatever the problem is I think that when I restart Dovecot I'm forcing Thunderbird to reconnect. Perhaps the solution is to somehow force Thunderbird to have to reconnect every time rather than have a persistent connection? Looking for suggestions. Thanks in advance.

[Dovecot] Store sent email
by pierre.casenove＠almerys.com 28 Jan '09

28 Jan '09

Hello all, I've set up a webmail solution based on RedHat EL 5, sendmail, spamassassin, clamAV and dovecot by following this tutorial: http://www.redhat.com/magazine/025nov06/features/email/index.html I have configured everything without any problem, I can send and receive emails, using Maildir store format. Now, what I don't know how to set up: I would like to store the emails sent by the users in a dedicated store (Like Sent Emails in many webmails).... and I've got no idea on how to do this! By googling a little, I found this thread ( http://www.dovecot.org/list/dovecot/2007-April/021447.html) where a plugin is mentionned. Has it been developped or is there another solution? I'm using dovecot 1.0.7, shipped with RHEL 5 distribution. I am really discovering all the products around the email so I'm a bit confused. Thanks a lot for your answer, Pierre

[Dovecot] dotlock timestamp trouble

Hi there, I'm getting a lot of this message in production log: Created dotlock file's timestamp is different than current time (1232468644 vs 1232468524): /path/to/dovecot.index.log The IT guy swears the clocks are sincronized.

[Dovecot] No Spaces in Directory names
by Matt Rude 27 Jan '09

27 Jan '09

How can I make it so my users can not create folders with spaces in them? Or allow them to create such folders but rewrite them on the hardrive with a "_" or some other symbol. I have looked threw the wiki but couldn't find anything about folder name restrictions or folder name rewriting (rewrite the space to a "_"). Im having problems with some of the expire and compress scripts when it hits these types of folders. Is dovecot able to restrict or rewrite the names of imap folders? dovecot -n # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.27.9-159.fc10.i686 i686 Fedora release 10 (Cambridge) ext3 listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/postfix/SSL/mail.mattrude.com.cert ssl_key_file: /etc/postfix/SSL/mail.mattrude.com.key login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: postfix mail_location: maildir:/var/spool/virtualmailboxes/%d/%u/imap/:INBOX=/var/spool/virtualmailboxes/%d/%u/ mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 cache_size: 128 cache_ttl: 600 master_user_separator: * passdb: driver: sql args: /etc/dovecot-mysql.conf passdb: driver: sql args: /etc/dovecot-sql-master.conf pass: yes master: yes userdb: driver: sql args: /etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: virtualmail group: virtualmail plugin: sieve: /var/spool/virtualmailboxes/%d/%u/dovecot.sieve sieve_storage: = /var/spool/virtualmailboxes/%d/%u/ quota: maildir quota_rule: *:storage=10M quota_rule2: Trash:storage=20% Thanks -Matt

[Dovecot] Dovecot discards mail over quota
by Gary V 27 Jan '09

27 Jan '09

I'm new to Dovecot, using 1.1.8 and I just wanted to verify that what I am observing is the intended behavior. I'm using Maildir++ quota. When a message is delivered to a mailbox that cannot accept the message because it would place them over the quota limit, deliver states to the MTA that the messsage was delivered successfully (example using postfix): Jan 17 12:05:31 msa postfix/pipe[13983]: 088C5B9D47: to=<test(a)example.com>, relay=dovecot, delay=0.72, delays=0.34/0.02/0/0.36, dsn=2.0.0, status=sent (delivered via dovecot service) But in actuality the mail is discarded (dropped). Then a bounce is created stating the mail was rejected: Your message to <test(a)example.com> was automatically rejected: Quota exceeded (mailbox for user is full). Question: is it possible (without changing code) to alter this to where deliver would instead tempfail or something. Somehow it seems wrong to me to tell the MTA that everything is good, and then silently discard messages - regardless of the fact dovecot creates a bounce. This is not necessarily ideal either, but I _am_ wondering if this is configurable or not. deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: save failed to INBOX: Quota exceeded (mailbox for user is full) deliver(test(a)example.com): 2009-01-17 12:05:31 Info: sieve runtime error: Keep: Generic Error deliver(test(a)example.com): 2009-01-17 12:05:31 Error: sieve_execute_bytecode(/var/sieve/global.sievec) failed deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: rejected: Quota exceeded (mailbox for user is full) deliver(garyv(a)example.com): 2009-01-17 12:05:31 Info: msgid=<dovecot-1232219131-401523-0@msa>: saved mail to INBOX -- Gary V

[Dovecot] behavior of dovecot with Openldap
by Masaharu Kawada 27 Jan '09

27 Jan '09

Dear team, I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows. In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below. hosts = ldap-server1.example.com ldap-server2.example.com ※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave). If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies? 1. only swithcing to the slave server 2. switching to the slave server, and once the master server is reactive then switch back to the master server automatically OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4 Thanks in advance, Masaharu Kawada ------------------- Masaharu Kawada Associate Global Support Engineer Red Hat K K Ebisu Neonato 8F 1-18 Ebisu 4-chome, Shibuya-ku Tokyo 150-0013, Japan Direct: +81-3-5798-8482

[Dovecot] FOLDER INTERNAL DATA (uw pine header)
by Charles Gregory 26 Jan '09

26 Jan '09

Hello! I run Dovecot on CentOS 4 (dovecot-1.1.4-0_81.el4), and I *also* run the "Alpine" mail system that comes with that OS. Alpine still writes out the 'FOLDER INTERNAL DATA' pseudo-message at the beginning of each user's mbox, but dovecot does not. I make use of that record as a simle/quick way to verify when a user actually last read their e-mail (for administrative purposes, identifying stale/unused accounts), so is there any way to configure/command dovecot to write (or update) these hidden messages? (Note: I tried looking in the archives, but most references seemed to be about this message being a 'side effect' of transferring *from* UW IMAP, and how to get 'rid' of it. Not what I need. :) Apologies if this was covered before in a different thread.) - Charles

[Dovecot] uint_cmp bug

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.

[Dovecot] Released ManageSieve v0.10.5 for Dovecot v1.1.9
by Stephan Bosch 26 Jan '09

26 Jan '09

Hello Dovecot users, Because there was a crash bug in the ManageSieve v0.10.4 login daemon, I made a new release of the ManageSieve service for Dovecot v1.1. This release includes two other small fixes as well. Changelog v0.10.5: - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed handling of ~/ in use of mail-data for script location The following files are released: ManageSieve package: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] userdb didn't return a home directory with v1.1.7
by Ivars Strazdiņš 26 Jan '09

26 Jan '09

Hi all, I am running Dovecot v1.1.7 in a relatively quiet and calm environment. Suddenly overnight cron job has started throwing out errors like: /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool Error: userdb(user1(a)mail.example) didn't return a home directory Error: userdb(user2(a)mail.example) didn't return a home directory Indeed, running this command produces: ------------------------- $ sudo /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool --test Error: userdb(user1(a)mail.example) didn't return a home directory Info: User lookup failed: user1(a)mail.example Error: userdb(user2(a)mail.example) didn't return a home directory Info: User lookup failed: user2(a)mail.example ------------------------- Yet these mailboxes are valid, corresponding users can login, send and receive mail. Other mailboxes are OK, too. Where to to start looking? I found that similar error message with v1.1.6 is fixed in v1.1.7, but I am running v.1.1.7 already. Please see dovecot configuration below.

[Dovecot] troubles with 1.1.8 and squirrelmail over HTTPS
by Frank Bonnet 26 Jan '09

26 Jan '09

Hello I noticed a problem after upgrading to 1.1.8 Users that access to their mailboxes using webmail squirrelmail and HTTPS using HTTP seems to work correctly but it not safe enough ... There is an error message saying the imap server send a BYE command ... I downgraded our Dovecot server to 1.1.7 then it works again ... Does somebody has the same problem ? -- Cordialement Frank Bonnet ESIEE Paris

[Dovecot] Shared Mailboxes (symlink) and kmail: known issues?
by Wilhelm Meier 26 Jan '09

26 Jan '09

Hi, are there any known issues with symlinked-shared-mailboxes and kmail? I use virtual users (LDAP), so there are no unix-permissions related problems here: all mailboxes are owned by the local user vmail. Each user maildir has some symlinks to shared mailboxes. This works fine if I use squirrelmail as a MUA. kmail instead seems to have some problems: if I save a mail into the shared-folder, the other users are seeing this new mail almost immediately. But if I delete(!) a mail from the shared-folder, the list of the other kmails remains untouch. Refreshing does nothing. I have to close kmail and restart. Is this related to some sort of wrong config of the shared mailboxes or is this a (known) dovecot <-> kmail problem? -- Wilhelm

[Dovecot] maildirfolder is created world-writeable
by Robert S 26 Jan '09

26 Jan '09

If I create a new folder using a mail client (eg. kmail/OE), the maildirfolder file is created world-writable. I assume that this is a security risk and should be -rw-------. eg. - create folder "Foo" in mail client ~ $ ls -la .maildir/.Foo/ total 20 drwx------ 5 robert users 4096 2009-01-21 19:56 . drwx------ 43 robert users 4096 2009-01-21 19:56 .. drwx------ 2 robert users 4096 2009-01-21 19:56 cur -rw-rw-rw- 1 robert users 0 2009-01-21 19:56 maildirfolder drwx------ 2 robert users 4096 2009-01-21 19:56 new drwx------ 2 robert users 4096 2009-01-21 19:56 tmp Some info: # dovecot --version 1.1.7 # dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27-gentoo-r7 x86_64 Gentoo Base System release 1.12.11.1 ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/.maildir mail_plugins: deleted_to_trash namespace: type: public separator: / prefix: Public/ location: maildir:/var/local/mail/public/ list: yes namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: * userdb: driver: passwd I can't find this is the bugs area.

Hi, I found the following in my logfiles: The failure is not reproducable at the moment. System is delivering mails to mailboxes with no problems at all. It is a production installation with medium load. dovecot --version: 1.1.7 OS: Linux (Gentoo/x86 stable) - grsec enabled kernel deliver.log: deliver(user(a)example.tld): Panic: file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) deliver(user(a)example.tld): Error: Raw backtrace: /usr/libexec/dovecot/deliver [0x80c8032] -> /usr/libexec/dovecot/deliver(default_fatal_handler+0x3a) [0x80c812a] -> /usr/libexec/dovecot/deliver [0x80c796c] -> /usr/libexec/dovecot/deliver [0x80cf5f8] -> /usr/libexec/dovecot/deliver(i_stream_read+0x2d) [0x80cc5dd] -> /usr/libexec/dovecot/deliver(i_stream_read_data+0x1d) [0x80cc6ed] -> /usr/libexec/dovecot/deliver [0x80d52cb] -> /usr/libexec/dovecot/deliver(o_stream_send_istream+0x35) [0x80d45b5] -> /usr/libexec/dovecot/deliver(maildir_save_continue+0x32) [0x806fbb2] -> /usr/libexec/dovecot/deliver(mail_storage_copy+0xd2) [0x8096512] -> /usr/libexec/dovecot/deliver(maildir_copy+0x5b) [0x806c51b] -> /usr/libexec/dovecot/deliver(deliver_save+0x17d) [0x805cbfd] -> /usr/libexec/dovecot/deliver(main+0x161b) [0x805e41b] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x559a7fdc] -> /usr/libexec/dovecot/deliver [0x805bb41] mta.log (postfix with dovecot/deliver pipe transport): Jan 22 00:02:09 argon postfix/pipe[21251]: E8126A3671: to=<user(a)example.tld>, orig_to=<localalias>, relay=dovecot, delay=0.38, delays=0.03/0/0/0.35, dsn=5.3.0, status=bounced (Command died with signal 6: "/usr/libexec/dovecot/deliver") Neither the grsec.log nor dmesg said anything special. The box had filesystem issues a month ago. I sucessufly fscked it. Do you think its a hidden fs problem or a dovecot issue?
