We still haven't found a solution, but here's what we've got thus far: - The issue is not VServer specific. We're able to reproduce it on recent vanilla kernels. - The issue has a strong correlation with the number of processor cores in the machine. The behavior is impossible to provoke on a dual core workstation, but is very widespread on 16 or 24 core machines. One of my colleagues has written a snippet of code that reproduces and exposes the problem, and we've sent this to the Inotify maintainers and the kernel mailing list, hoping that someone more familiar with the code will be quicker to figure out what is broken. If anyone's interested - either in following the issue or the code snippet that reproduces it - here's the post: http://thread.gmane.org/gmane.linux.kernel/1315430 As this is clearly a kernel issue, we're going to try to keep the discussion there, and I'll probably not follow up here, until the issue has been resolved.

Re: [Dovecot] director map and mysql
thanks! but what mechanisms do I have if I want certain user to be always proxied to certain host, but if that host is down, to redirect him to another? I planned to setup two dovecot storage servers where all mailboxes are mirrored between these two servers with dsync replication like described in http://www.dovecot.org/list/dovecot/2012-March/064243.html but I don't want this user to be redirected to two these servers in round-robin fashion. -Original Message- From: dovecot-boun...@dovecot.org [mailto:dovecot-boun...@dovecot.org] On Behalf Of Timo Sirainen Sent: Wednesday, June 20, 2012 1:22 PM To: Костырев Александр Алексеевич Cc: dovecot@dovecot.org Subject: Re: [Dovecot] director map and mysql On 20.6.2012, at 5.03, Костырев Александр Алексеевич wrote: > Is "doveadm director map" command suppose to work when I store "host" value > in mysql table? > It gives me nothing in output with no errors in log.

[Dovecot] director map and mysql
hello!
Is "doveadm director map" command suppose to work when I store "host" value in
mysql table?
It gives me nothing in output with no errors in log.
I've successfully setup directors with static passdb, and decided to give a try
setup with storing host value in mysql table.
The proxying is actually working, I'm just unhappy with no output from "doveadm
director map".
on the other hand output from "doveadm director map" is not empty, when I
configure my password_query not to return host from table.
director's settings in dovecot.sql is:
passdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf
}
userdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf
}
director_servers = 192.168.5.125
director_mail_servers = 192.168.5.110 192.168.5.111
service doveadm {
inet_listener {
port = 24245
}
}
protocol doveadm {
auth_socket_path = director-userdb
}
doveadm_proxy_port = 24245
in /etc/dovecot/dovecot-sql.conf at director there's
password_query = SELECT \
NULL AS password,\
'Y' as nopassword, \
'Y' AS proxy, \
MBOX_NAME as user, \
host2 as host \
from M_MAILBOX \
where MBOX_NAME = '%u'
user_query = SELECT \
MBOX_NAME AS username, \
MAIL_DIRECTORY as home \
from M_MAILBOX \
where MBOX_NAME = '%u';
iterate_query = select MBOX_NAME AS username from M_MAILBOX;
backend's conf:
service doveadm {
inet_listener {
port = 24245
}
}

Please check your system date and the retention times of mails in your trash mailbox. Right click on the folder. Regards Daniel
[Dovecot] message parser: Fixed infinite loop when parsing a specific message.
I committed this change to all hg branches: http://hg.dovecot.org/dovecot-2.1/rev/4461b48fcc1f After that I realized that it doesn't actually matter, because it fixes only a situation where input buffer's size is less than 84 bytes. This happened on a test program where I was using a 64 byte buffer, but the real code in Dovecot always uses much larger buffers. So, don't worry, there's no way to actually DOS Dovecot with this. No need for distro people to create any security releases.

Any ideas?
P.S.: Sorry for the bad english.

I used an imap client to create an imap folder named "unpack" , searched for the messages I needed and then moved them into the unpack folder.

[Dovecot] specifying home/sieve/sieve_dir relative to mail_location
With 1.2, is it possible to specify home, sieve and sieve_dir relative to mail_location? I have mail_location = maildir:/import/mail/%n/:INDEX=/var/db/dovecot/indexes/%n and, in the plugin section, home = /import/mail/%n/home sieve = /import/mail/%n/dovecot.sieve sieve_dir = /import/mail/%n/sieve I would like to partially move users to another location (different file server) by using an LDAP entry. I know it's possible to specify everything relative to home, so I could probably use relative ~/../-type paths for mail_locatin etc., but that looks a bit awkward. The VirtualUsers/Home Wiki enty contains an example for relative paths user_attrs = .., mailDirectory=home=/var/vmail/%$ which I do not understand.

Indeed they did not. I incorrectly thought that a line in postfix's main.cf
would change the delivery to deliver. That would have been true if I used local
delivery. For virtual users postfix is using "virtual" by default. So I had to
add deliver to postfix's master.cf and change the virtual_transport in main.cf.
After configuring logging for deliver I can now confirm that it is used. I was
mistaken by thinking local delivery is the same as virtual delivery. I could

Don't add a dot on the beggining of the folder name in sieve scripts.
Use fileinto :create "folder" or lda_mailbox_autocreate option to create
non-existing folders.
