[Dovecot] sieve and namespace
HI I'm tryin to set up sieve the way so it will put incoming message into Junk folder, which is described via namespace. Unfortunately rule doesn't work and message is put into Inbox. If i change destination folder to folder not described via namespace in the same rule the message is placed to that folder. please help dovecot 1.2.9 namespace: type: private prefix: Junk/ location: maildir:/opt/mail/Junk/INBOX:LAYOUT=fs hidden: yes list: yes subscriptions: yes

[Dovecot] Dovecot not liking AD config from wiki??
Hi,
I'm trying to setup Dovecot with MS AD and am using this as my guide:
http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm
I can definitely access information on the AD server using wbinfo -g
and wbinfo -u.
Currently my dovecot.conf file looks like this:
# v1.1:
#auth_ntlm_use_winbind = yes
# v1.2+:
auth_use_winbind = yes
auth_winbind_helper_path = /usr/local/bin/ntlm_auth
protocols = imap
# It's nice to have separate log files for Dovecot. You could do this
# by changing syslog configuration also, but this is easier.
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot-info.log
# Disable SSL for now.
ssl = no
disable_plaintext_auth = no
# We're using Maildir format
#mail_location = maildir:~/Maildir
mail_location = mbox:/mail:INBOX=/mail/%u
# If you're using POP3, you'll need this:
#pop3_uidl_format = %g
# Authentication configuration:
auth_verbose = yes
auth_debug = yes
auth_username_format = %n
auth_mechanisms = plain ntlm login
userdb {
driver = static
args = uid=501 gid=501 home=/mail/%u
driver = static
allow_all_users=yes
}
According to the documentation I should be using:
userdb static {
...
}
which seems to be Dovecot v1. config, and additionally the
allow_all_users=yes statement when added seems again v1. config
since Dovecot 2. won't even start?
In the meantime when not using allow_all_users Dovecot throws up these errors:
Jun 20 11:30:40 master: Warning: Killed with signal 15 (by pid=4149

Jun 20 11:30:48 auth: Fatal: No passdbs specified in configuration

with signal 11 (core not dumped - set service auth {
drop_priv_before_exec=yes })
-- this was after adding:
passdb {
driver = static
}
to the mix.
I'm using Dovecot 2.1.3 on FreeBSD 8.2 RELEASE x64.
Can anyone help me configuring Dovecot to authenticate?

[Dovecot] dovecot 2.1.5 performance
Hello, I'm migrating from 1.1.16 running in 4 debian lenny servers virtualized with xenserver and 1 core and 5GB of RAM to 2.1.5 running in 4 ubuntu 12.04 servers with 6 cpu cores and 16GB of RAM virtualized with VMWare, but I'm having lots a performance problems. I don't think that virtualization platform could be the problem, because the new servers running in xenserver has the same problems than running in vmware. I have about 7 user accounts, most of them without real activity (they are students who doesn't read his email or have its account redirected to other provider). I have about 700-1000 concurrent imap connections. I have storage in nfs (nfsv3, the nfs server is a celerra), but indexes are in local filesystems (each server has its own index fs). Mailboxes are in maildir format. Old servers and actual director servers are load balanced with an radware appdirector load balancer (the new backend servers don't need to be balanced because I'm using a director farm) In the old platform I have scenario number 2 described at http://wiki2.dovecot.org/NFS, but in the new ones I have a director proxy directing all connections from each user to the same server (I don't specify any server for the user, director selects it according to the hash algorithm it has). Some doubts I have for the recommended in that url: * mmap_disable: both single and multi server configurations have mmap_disable=yes but in index file section says that you need it if you have your index files stored in nfs. I have it stored locally. Do I need mmap_disable=yes? What it's the best? * dotlock_use_excl: it is set to no in both configurations, but the comment says that it is needed only in nfsv2. Since I have nfs3, I have it set it to yes. * mail_nfs_storage: In single server is set to no, but in multi server it set to yes. Since I have a director in front of my backend server, what is the recommended? With this configuration, when I have a few connections (about 300-400 imap connections) everything is working fine, but when I disconnect the old servers and direct all my users' connections to the new servers I have lot of errors. server loads increments to over 300 points, with a very high io wait. With atop, I could see that of my 6 cores, I have one with almost 100% waiting for i/o and the other with almost 100% idle, but load of the server is very, very high. With the old servers, I have performance problems, access to mail is slow, but it works. But with the new ones it doesn't work at all. Any idea? -- Angel L.

One IP is always directed to the same server (during a session timeout, today could be one server and tomorrow another different), but mail is delivered randomly through one of the server. * Since last week (when we started migration) all mail is delivered into the mailboxes by the new servers, passing through director. So new server's indexes should be updated. mail_fsync = always v1.1 did the equivalent of mail_fsync=optimized. You could see if that makes a difference. I'll try this. maildir_stat_dirs = yes Do you actually need this? It causes unnecessary disk IO and probably not needed in your case. My fault. I understood the explanation completely wrong. I thought that yes should do what actually does no. I have fixed it. default_process_limit = 1000 Since you haven't enabled high-performance mode for imap-login processes and haven't otherwise changed the service imap-login settings, this means that you can have max. 1000 simultaneous IMAP SSL/TLS connections.

Re: [Dovecot] dovecot 2.1.5 performance
I know it. I have to tune it. -- he did not only changed Dovecot but OS. I would bet it is his OS problem - as he stated 100% of single core is used while 6 are available. something definitely not dovecot dependent. i would recommend installing exactly the same version of old dovecot on new OS and test it.

[Dovecot] GlusterFS + Dovecot
Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..? It says that it can be presented as a NFS, CIFS and as GlusterFS using the native client, technically using the client would allow the machine to read and write to it, therefore, I think that Dovecot would not care about it. Correct? Anyone out there used this setup?? Thanks.

I've heard Dovecot complains about index corruption once in a while with glusterfs, even when not in multi-master mode. I wouldn't use it without some heavy stress testing first (with imaptest tool).
[Dovecot] Dovecot list IMAP archives with thunderbird?
Hi, I'm trying to access the IMAP archives with Thunderbird but can't seem to get it to work. I have tried an unencrypted connection, SSL and TLS but with no success. Any ideas?

[Dovecot] Problem with Dovecot 2.0/2.1 and MySQL 5.1
Hi everyone,
since some time I got problems with dovecot mysql.
I got the problem with version 2.0.x and upgraded to 2.1.7 to check if
its gone. But its not :(
The logs just tell me this:
dovecot: auth: Error: auth worker: Aborted request: Worker process died
unexpectedly
If I change to a sqlite setup, everything works fine.
Here are some informations. I hope someone can tell me whats wrong with
my system/setup. I really dont think that this is a bug because someone
else should have hit that before me.

Since most of our Crystal Balls are broken, you will likely have to
be much more precise in your request for help, by providing actual
excerpts from logs while accessing mail, and you may even have to
resort to enabling debugging...
Start here: http://wiki2.dovecot.org/WhyDoesItNotWork
Otherwise, you may get more help from a Fedora support list.

Each email I receive in the INBOX folder are missing the core of the

In other folder the email come in just fine

Re: [Dovecot] migrating sql virtual 1 to 2, namespace configuration error: inbox=yes namespace missing
Timo, thanks Timo Sirainen t...@iki.fi wrote: Easiest fix: remove 15-mailboxes.conf This didn't seem to fix it, though, perhaps I failed to test it properly Alternative fix: modify this namespace to actually work. Probably adding inbox=yes inside it is enough to do that. With some trepidation, I inserted the string where I thought it should go, and, bingo, it started working as expected. I probably should removed the full path from SQL query, and put in the Conf file as docs suggest, but I might leave that for another day. Thank you again, Voytek -- Swyped on Motrix with K-9 Mail. Please excuse my brevity.
