[Dovecot] AIX: mntctl implementation for NFS quota support
by Ralf Becker 21 Jul '08

21 Jul '08

Hi Timo, Hello list, I've played around with dovecot-1.1.1 on AIX to get quotas (especially NFS quotas) to work. I've found that dovecot doesn't implement handling of 'mntctl' and so it is unable to determine filesystem mountpoints on AIX correctly. Your'll find more information about 'mntctl' here: http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.a… Okay... I've added mntctl support to 'lib/mountpoint.c' today. My tests are looking good and so I'd like to share the patch. While I'm still not really familiar with dovecots memory management, I need someone who is familiar with it to have a look on my lines of code. Especially the usage or p_new, t_strconcat and p_free should be checked. :-) To activate the patch you have to add "#define HAVE_VMOUNT_H 1" do 'config.h'. Maybe someone wants to alter configure* to do this automatically? And of course Timo, if you find it useful, you may include the code in one of the next dovecot releases.

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc13.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc13.tar.gz.sig There's always time for one more release candidate. :) I was planning on releasing v1.1.0 a couple of minutes before summer solstice (23:59 UTC according to Wikipedia). Maybe it'll bring luck to the release. :) - mbox: Fixed a crash when adding a new X-IMAPbase: header with keywords. - Message parser: Fixed assert-crash if cached MIME structure was broken. - Squat: Potential crashfix with mmap_disable=yes.

[Dovecot] exim, LDA, quota
by Marcin Gryszkalis 20 Jul '08

20 Jul '08

Hi I configured Exim with dovecot LDA and added quota (dict/mysql). It works but it seems that dovecot is not reporting situation back to exim process - it looks like Exim returns OK(accepted) to smtp sender before the message is actually delivered - if the quota is exceeded then LDA drops the mail and sends DSN. Is it possible to change that behavior to report problem immediately (within SMTP session)? regards -- Marcin Gryszkalis, PGP 0x9F183FA3 jabber jid:mg@fork.pl, gg:2532994 http://the.fork.pl

[Dovecot] group ownership of new shared folders
by Simon Michelson 20 Jul '08

20 Jul '08

Between versions 1.0.4 and 1.0.5 there were some changes to the way dovecot-shared group ownership is propogated into new maildirs. Changing the group of new_dir/{tmp,new,cur} was added, but changing the group of new_dir itself was removed. As far as I can tell, this latter change may have been accidental.

[Dovecot] No log for hitting login_max_processes_count?
by Adam McDougall 20 Jul '08

20 Jul '08

I think today just due to increased use, my mail servers hit login_max_processes_count. It wasn't obvious what was happening, logins just weren't acting like they should and sometimes would get disconnected before given a prompt from the server. Something made me think to check if I had too many of certain dovecot processes and I found I had 128 imap-login processes on both servers, but nothing in the logs seemed to point that out for me. Should there be? It would have been alot easier to debug. Also, this seems to be from general use, doesn't seem like a DoS, so is this just a setting I should keep an eye on and increase it by reasonable amounts as needed? Thanks.

[Dovecot] 1.1.1, mbox_snarf and duplicate messages
by Laurent.Moineau＠math-info.univ-paris5.fr 20 Jul '08

20 Jul '08

Hello, I recently switched to dovecot 1.1.1 with mbox_snarf from uw-imap with mbox driver enabled. The mail is delivered by procmail in /var/spool/mail/user Most of my users have a file INBOX located in $HOME/mail The mail is transfered from /var/spool/mail/user to $HOME/mail/INBOX every time an imap connection is done. Things are OK with clients like thunderbird or evolution, but with imp or mostly squirrelmail messages are duplicated (some user reported that a single message duplicated 50 times !). Every imap connection (thunderbird or webmail) terminates with a warning : Timeout leak: 0x4534e0 I 've tried to use fcntl in : lock_method, mbox_read_locks and mbox_write_locks but things are worse than traditional dotlocks. My config on my first server : sendmail-8.14.1 procmail dovecot 1.1.1 On the second server : The webmail (imp and squirrelmail, latest versions) is installed on another server but uses server 1 as imap server. I 've tried to use an imap proxy (perdition) but without any improvement as far as this problem is concerned. I previously used another dovecot server on that machine with an NFS mount to get /var/spool/mail from the first server with the duplicate problem too. I enabled mail_log and there where a bunch of Info messages like this : dovecot: Jul 11 18:20:11 Info: IMAP(foo): copy: uid=22, dest=/users/foo/mail/INBOX, msgid=<4877879C.40104(a)math-info.univ-paris5.fr>, size=2223 Any hint ?

[Dovecot] 'include' feature in sieve 1.1.5
by Zhang Huangbin 20 Jul '08

20 Jul '08

Hi, all. I use dovecot-1.1.1 and dovecot-1.1.5 which built by atrpms, and i use 'include' command to include two/several personal sieve rule file, but if either of these personal sieve rule files is not exist, sieve_execute_bytecode failed. How can i make it just skip the non-exist personal sieve rule file, and continue to try to include next sieve rule file?

Hi all. Looking at previous weeks logs I discovered strange errors: "file mail-transaction-log-view.c: assertion failed" dovecot v 1.0.12 Server is hosting more than 500 virtual users.

[Dovecot] Multiple auth client sockets
by Ulrich Zehl 20 Jul '08

20 Jul '08

I use two seperate Postfix instances as MSAs (so that different policies are simpler to configure), and both of them require Dovecot SASL support. Since Postfix' smtpd is chrooted (at least in the Debian package), the client socket needs to be somewhere under the instance's queue_directory. This means I need two different auth client socket paths. When I simply specify two "client { ... }" in dovecot.conf, the second takes precedence over the first. Besides using a second dovecot instance, which I'd like to avoid, what ways are there to run a second client socket? Ulrich

[Dovecot] [Help] quota_rule with LDAP backend, dovecot-1.1.1
by Zhang Huangbin 20 Jul '08

20 Jul '08

Hi, all. I use dovecot-1.1.1 with OpenLDAP as userdb. but i failed to convert quota value as expect. I set '10' as mail quota, and it should be '10M' as expect, but it's not effect, dovecot always uses 'quota_rule' setting in dovecot.conf. How can i fix this issue? 10*1047576? I have 'mailQuota' attr in ldap schema, such as: ----8<---- mailQuota: 10 # <- 10M ----8<---- My dovecot-ldap.conf: ----8<---- user_attrs = homeDirectory=home,mailMessageStore=maildir:mail,mailQuota=quota_rule=*:bytes=%$ ----8<---- And my dovecot.conf: ----8<---- plugin { quota = maildir # Quota rules. quota_rule = *:storage=10M } ----8<---- -- Best Regards.

[Dovecot] configuration query
by Michael Mounteney 20 Jul '08

20 Jul '08

Hello, please excuse my asking a question about simple configuration rather than something about a suspected bug or other detailed enquiry. I've set up dovecot (1.0.13, from http://www.blastwave.org) and when Thunderbird connects to it, all is well and I see folders as expected. When MacOS X mail connects however, it sees my home directory on the dovecot machine, not the mail directory. Now setting-aside the obvious rant about why MacOS has to be gratuitously different *again*, I would like to configure dovecot not to serve my home directory. I keeping saying I/my as this is just a personal set-up at home. This IMAP stuff is a bit involved but I thought namespaces would be the answer but it seems not. That is, I have namespace private { location = /var/marchive/%u inbox = yes } but even this still allows Mac Mail to see the home directory. What else should I do to stop dovecot serving my home directory ? I realise that there is also a problem with the client, that Mac Mail is *asking for* my home directory rather than the mail folder, but that's another problem, not for this list. Thanks in expectation.

[Dovecot] BUG: messages created with permissions not respecting umask
by Thomas Vander Stichele 20 Jul '08

20 Jul '08

Using dovecot 1.0rc15, together with postfix and dovecot-lda. umask is set to 0007. This should ensure directories and files get created with read/write permissions for both user and group. However, dovecot-lda writes files with 600 permissions, instead of 660. So dovecot does not seem to respect the umask configuration property for local mail delivery. In my particular case, I have vmail:vmail own the mail directories, and a backup user part of the vmail group. However the backup user cannot read the mails and thus back them up properly. Suggestions: - respect the umask for file delivery as well - alternatively, take the parent directory's permissions, strip executable bits, and apply to file Thanks Thomas

[Dovecot] Run script before delivery
by Juan Asensio Sánchez 20 Jul '08

Hi Is it possible to run one script before the "real" delivery of a message (with lda, or before the execution of the sieve scripts) but after the creation of necessary folders (Dovecot automatically creates the folders for virtual users)? I want to to this to manually create a fixed empty sieve script in each user home folder, so in the global sieve script include that personal script, because if personal script doesn't exists, global script is not executed, or am I wrong? Thanks in advance.

[Dovecot] Need suggestion regarding index file and Quota settings.
by Tim Chen 20 Jul '08

Dear All, My system has about 30,000 accounts and these accounts are created as unix system users. Each account has its own entry in /etc/passwd with different UID and home directory. We plan to deploy an Layer 4 switch as a load balancer. Proposed architecure is as the following: ---- internet ---- Layer 4 switch ---- mail server1 ---- NFS storage | | |--- mail server2 -----| Both mail servers will share the same storage which contains users' home with Maildir inside. Dovecot will be installed on the mail servers serving pop3 and imap4 protocols. Since the layer 4 switch will direct connection to backend mail server in random(or some of its algorithm), users can not guarantee which mail server to use. My first question is which kind of INDEX settings should I apply? 1) INDEX=MEMORY 2) INDEX=/nfs/%u 3) INDEX=/var/spool/%u Will INDEX stored on disk outperform INDEX stored in memory? If INDEX stored on NFS storage, we can be sure the consistency of INDEX file, but what about the performance and locking problem? If INDEX stored on local disk, since users may connect to different mail servers every time. Will that impose the problem of inconsistency? What kind of syndrome will happen if the INDEX became inconsistent to real maildir content? My second question is about quota. We use maildir as mail storage format. Our users were divided into 3-4 groups, each group of users with different quota size ranging from 100MB - 1G. To my best knowledge, dovecot's quota setting in config file supports only "one global configuration". (We are not using db, we use only /etc/passwd). dovecot.conf quota_rule = *:storage=10MB Since dovecot supports both fs and maildir++ quota, I would like to ask for your suggestion: 1. Should I use system quota instead? How about the comparision of performance? Is there any drawback/limitation using system quota? 2. Is there any settings of dovecot that could fullfil my situation? 3. My thought is to modify dovecot.conf, comment out quota_rule = *:storage=10MB and leave only the quota = maildir in the plugin { block. According to my experiment, dovecot will read the maildirsize file under user's home. Then I have to set the maildirsize file for every user individually! It seems to be a little crappy but works. Looking for your valuable suggestions! Thanks very much. Tim Chen
