[Dovecot] Question about mbox_snarf and dovecot2.0
by Jonathan Siegle 18 Nov '10

18 Nov '10

Hello, I'm running revision 10622:de9d6dae7fe5 on AIX 5.3 with some local mods for our inbox hash function. I'm having a problem doing a "select inbox" when I use the mbox_snarf plugin. When I run truss on the process I see the following stat calls: 614528: kread(9, " 1 s e l e c t i n b".., 4096) = 15 614528: statx("/gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFF2F8, 176, 0) = 0 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/.imap/tstem38", 0x0FFFFFFFFFFFED98, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFEDD8, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP", 0x0FFFFFFFFFFFEC88, 176, 0) = 0 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFEDD8, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP", 0x0FFFFFFFFFFFEC88, 176, 0) = 0 and the client gets: 1 NO [CANNOT] Invalid mailbox name For pathing I have: plugin.conf: mbox_snarf = /gpfs/inbox/%Ju/%u and mail.conf:mail_location = mbox:%h:INBOX=/var/spool/mail/%Ju/%u I verified that not using the mbox_snarf works just fine. I have no namespaces enabled. Thanks, Jonathan

[Dovecot] Dovecot and user's quota
by oriol llistes 18 Nov '10

18 Nov '10

Hi, We are planning to use Dovecot-2.0.5 (Maildir format) as IMAP server. Currently, we are using Postfix+UW-Imap (mbox format) with the following configuration: - Postfix: Sends new messages to /var/mail/user - UW-IMAP: Reads mails from /var/mail/user and moves them to ~/nsmail/mbox Using that configuration, when a user overtakes his HOME’s quota, the MTA is still able to send new messages to the user, although he cannot read it until he frees HOME space. Can we configure Dovecot to work in the same way? I mean… 1)Postfix must use /var/mail partition for new mails. 2)Dovecot must move these mails to user’s HOME. 3)User’s HOME must be in Maildir format. If that is not possible, how can we achieve an equivalent solution? Thanks in advance. Oriol.

[Dovecot] dovecot with Active Directory problem
by marie ot 18 Nov '10

18 Nov '10

Hello, I am using dovecot-2.0.6 with NetBSD amd64. Active Directory is used as an authentication server. (Windows Server 2008 R2) However, the message of "Operations error" was displayed first and it did not move. It solved it by understanding that this is because the authority of the user who used it for bind was insufficient, and adding to "Account Operators" group. # Though it is not the best. The error "Error: re_encode_request new request is" occurs, and it doesn't operate still as follows. Postfix operates though connects with LDAP. The following are samples. ------------------------ # Active Directory Server settings domain = example.com server_host = ldap://xxx.xxx.xxx.xxx:389 search_base = dc=example, dc=com version = 3 timeout = 30 # Active Directory Searcher settings bind = yes bind_dn = cn=Mail Administrator, cn=Users, dc=example, dc=com bind_pw = ********* # Filter Query query_filter = (&(&(objectCategory=person)(|(mail=%s)(userPrincipalName=%s)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = userPrincipalName result_filter = %s/ chase_referrals = no ------------------------ The packet was done with wireshark by using this definition and a capture doing and a similar test were done to dovecot. It is a setting of dovecot. ------------------------ hosts = xxx.xxx.xxx.xxx:389 dn = cn=Mail Administrator, cn=Users, dc=example, dc=com dnpass = ********* auth_bind = no ldap_version = 3 base = dc=example, dc=com user_attrs = unixHomeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPrincipalName=user,unixUserPassword=password pass_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) iterate_attrs = userPrincipalName=user iterate_filter = (&(objectCategory=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) default_pass_scheme = MD5 ------------------------ # Schema of LDAP is matched to Windows Services for UNIX, # and the password is made a hush with MD5. Both dovecot and postfix the first "bindRequest" was quite the same demand and the results. Next, dovecot demanded query of "userPrincipalName" and "unixUserPassword". It seems to be ok for the result. # This fails if it doesn't add to "Account Operators" group. However, "name" and "simple" were issued by the blank (anonymously?) as for the following next demand (bindRequest). In addition, query of "userPrincipalName" and "unixUserPassword" is issued to "cn=Configuration, dc=example, dc=com" afterwards. And, "Operations Error" is returned because of this. Error description in LDAP packet: ------------------------ errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0 ------------------------ Because LDAP is unprofessional, it has not understood though the source code was seen. Do you serve as a reference? Thanks powerful codes.

[Dovecot] Multiple MYSQL hosts as passdb backend
by moody_cz 18 Nov '10

18 Nov '10

Hello, I use mysql as passdb backend for my dovecot 2.0.6 installation. I have 2 mysql 5.0.77 servers with master/slave replication enabled. My goal is to ensure dovecot's ability to provide its services even when one of the mysql hosts are unavailable. Here is my passdb backend conf: passdb { driver = sql args = /etc/dovecot/mysql.conf } and mysql.conf: default_pass_scheme = PLAIN driver = mysql connect = host=10.0.0.3 host=10.0.0.4 dbname=some_database user=some_user password=some_password password_query = some_query Everything works fine as long as 10.0.0.3 is up and running. However, when I shutdown mysql server on 10.0.0.3, dovecot won't even try the other host 10.0.0.4 as it is told to do in the conf. My dovecot verbose log says: Nov 16 14:29:24 auth: Error: mysql: Query failed, retrying: MySQL server has gone away Nov 16 14:29:24 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:30:28 auth-worker: Error: mysql: Query timed out (no free connections for 64 secs): some_sql_query Nov 16 14:30:28 auth-worker: Error: sql(mail_user,127.0.0.1): Password query failed: Not connected to database Nov 16 14:30:28 auth: Error: auth worker: Aborted request: Lookup timed out Nov 16 14:30:28 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:31:33 pop3-login: Info: Disconnected (auth failed, 1 attempts): user=<mail_user>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured What am I doing wrong?

[Dovecot] Debian package init scripts
by Jan Behrend 18 Nov '10

18 Nov '10

Dearest list, I am using dovecot with heartbeat-2 and I noticed that the init scripts in the Debian packages from http://xi.rename-it.nl/debian/ do not conform to the LSB standard: http://refspecs.freestandards.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-gener… E.g. the return code for "program is not running" is not 3. Is there is special reason for this?

[Dovecot] add basic systemd support to dovecot
by Christophe Fergeau 17 Nov '10

17 Nov '10

Hi all, In the last days, I've been trying to add support for systemd[1] socket activation to dovecot. The basic idea is that systemd takes care of opening the sockets needed by dovecot to communicate with external processes, and when a connection happens on one of these sockets, systemd spawns dovecot, and then dovecot uses these sockets instead of creating its own sockets. The main reason why I hacked on this was that I wanted to get on-demand startup of dovecot on my home box. WIth the patch attached to this email, I'm now able to do that. The patch includes a dovecot.socket file which should be seen as a sample file, however I'm not sure what is the best way to handle this file (systemd uses it to know which sockets dovecot needs). What I wanted to ask the list for now is if such a patch is wanted, and to get feedback on how things are done in it, and what should be improved in it. [2] and [3] might be useful reading while looking at the patch. Thanks in advance for the feedback!

[Dovecot] Ongoing performance issues with 2.0.x
by Ralf Hildebrandt 17 Nov '10

17 Nov '10

Due to the ongoing performance issues with 2.0.x I switched back to 1.2.15 yesterday evening, with no changes to the machine or my users. (I migrated from 1.2.15 to 2.0.x by converting the existing config) Today, we have MUCH LESS load, with the same number of logins/min. I cannot say what exactly causes this immense increase in load, but one observation is that the time spent in system() has now dropped (user and iowait have stayed contant) to a third of the values I was seeing with 2.0.x. This evening I'll post some graphs showing two comparable 24 hour ranges. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de
