[Dovecot] Strange index problem
by Andrew Hutchings 09 Aug '05

09 Aug '05

Hi, OK, I have 2 servers accessing the same mailboxes via NFS (indexes on each servers local HDD). They are on a round robin connection system. I have had a mailbox (customer using Eudora for Mac and storing mail for a certain amount of days) that on one server says there are 281 messages and the other says there are 194 messages. Of course this leads to re-downloading the difference. The mails that are invisible to the second machine are not sequential, they are at random places in the mailbox. Deleting the indexed on the machine that is inconsistent seems to fix it. We seem to get this problem about once a week or 2 over 6000 mailboxes.

[Dovecot] Re: Problem with dovecot and system crashing
by Paul Vatta 09 Aug '05

09 Aug '05

We have experienced similar problems with version 0.99.11 that comes with Redhat Enterprise Linux 4. If I'm not wrong, it appears to be related to the number of file descripters available to the dovecot user. To abate the situation, we stop the service, kill any remaining dovecot processes (some hang around), and then restart dovecot. Sometimes it appears that the limit of connection processes isn't honoured (as defined in the conf file) so the number can spiral out of control. I hope this helps in the absense of a workaround. Let me know if there is an obvious configuration setting to remedy this.

[Dovecot] out of disk space notification
by David Weilers 09 Aug '05

09 Aug '05

Hi Dovecot readers, My server (squirrelmail) provides me with the following error-message when selecting a mailbox (trash): ERROR : Could not complete request. Query: SELECT "Trash" Reason Given: Out of disk space The user is not over quota but for some reason dovecot still thinks this to be true. Can anyone give me a hint for finding a solution for this problem. I have installed: dovecot-0.99.10.9-2.0.rh9.dag Thanks in advance.. David

[Dovecot] corrupted binary tree and index data files
by Gary Sandine 09 Aug '05

09 Aug '05

Hi. I am using dovecot 0.99.14 as an imaps server with mbox folders (in an NFS-mounted directory) in x86 Debian testing. I have searched the archives of this list and have seen other evidence of the problems I am having. I get lots of log messages like these: Jul 29 07:47:09 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/.imap/INBOX/.imap.index.tree: UID to be inserted isn't higher than existing (290 <= 291) ... Jul 29 07:47:13 HOST imap(USER): Corrupted index data file /home/USER/IMAP_MBOX_DIR/.imap/INBOX/.imap.index.data: Field 1 size points outside file (14648 / 14656) for record 290 This is from the midst of a herd of messages starting at 82 <= 144: Jul 28 08:01:31 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (82 <= 144) ... Jul 28 08:01:32 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (143 <= 144) Jul 28 08:01:32 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (144 <= 144) Jul 28 08:01:32 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (92 <= 154) Jul 28 08:01:32 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (93 <= 154) ... Jul 28 08:01:32 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (101 <= 154) Jul 28 08:01:34 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/SUBFOLDER_DIR/.imap/MBOX2/.imap.index.tree: UID to be inserted isn't higher than existing (79 <= 80) Jul 28 08:01:34 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/SUBFOLDER_DIR/.imap/MBOX2/.imap.index.tree: UID to be inserted isn't higher than existing (80 <= 80) Jul 28 08:11:27 HOST imap(USER): Corrupted binary tree file /home/USER/IMAP_MBOX_DIR/FOLDER_DIR/.imap/MBOX1/.imap.index.tree: UID to be inserted isn't higher than existing (102 <= 164) ... I don't know how to reproduce this. It happens (repeatedly) for some users and seems to be independent of the number of mboxes, mbox sizes, mail client, .... I have tried deleting .imap directories, and this helps for a while, but the problem always comes back for a few users. The proposed solution for "Corrupted binary tree" or "Corrupted index data file" log messages is usually to change to a different version of dovecot. I will try that, but want to check in here first in case something obvious is happening that I don't understand. Thanks, -- Gary Sandine <gars(a)lanl.gov>

[Dovecot] Header problems
by Andrew Hutchings 08 Aug '05

08 Aug '05

Hi, I don't know if this has been covered or not as I have been out of action most of the last few weeks getting married and stuff. My query / slight problem is when I re-install an IMAP client or change client all mails that have been read so far show an empty header with the date set back to 1970 but the mails are fully readable. New mails that weren't read in a previous client show fine. Could this be something do to with me using fcntl? I am using the latest test version with Maildir boxes. I haven't got any diagnostic data of this yet, I want to make sure this isn't a common problem first.

[Dovecot] directory names - have to begin with a dot?
by Tom Alsberg 07 Aug '05

07 Aug '05

Hi there... Two questions: (1) Is there an easy way to have Dovecot recognize subdirectories that do not begin with a dot as sub-hierarchies? (2) Is there a way to have the root folder map to a certain other mbox/maildir? I want a setup like this: / -> $HOME/mbox /INBOX -> /var/spool/<username> /folder -> $HOME/mail/folder /folder/foo -> $HOME/mail/folder/foo /folder/bar -> $HOME/mail/folder/bar /folder/foo/bar -> $HOME/mail/folder/foo/bar (Assuming / as a hierarchy separator - that is, /folder/foo/bar is the IMAP folder 'bar' inside 'foo' inside 'folder') The idea is something resembling and compatible with the default behaviour of elm/pine/mutt/KMail/evolution, so a user can use both those locally and whatever IMAP client remotely in a similiar organisation... I would love some further documentation regarding the working of Dovecot's folder lookup and how to achieve different IMAP folder organisations with dovecot. I have not yet looked deep enough into the sources to understand where most of the flexibiliy stems.

[Dovecot] auth_passdb using MySQL fails at starup
by Josh Joslyn 07 Aug '05

07 Aug '05

I've got dovecot v0.99.14, MySql 4.1.11 and postfix on fedora core 4. when using uxix socket I get: dovecot-auth: MySQL: Can't connect to database vmail: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) when using tcp socket I get: dovecot-auth: MySQL: Can't connect to database vmail: Can't create TCP/IP socket (13) * the mysql.sock exists * I can connect to mysql -u vmail and select on the table mailbox * I can run mysqladmin successfully using the port or the socket As you can see below I modified the password query to be very simple. I am surprised to get the error on startup since the password query should not be executed at this point. The problem is not MySql as I am able to query all day long the the vmail database table called mailbox with the vmail user. Not sure what else I can check Dovecot error message lacks the reason it can not connect - unless the (13) means anything to anybody??? Anybody have any ideas??? dovecot.conf : . auth_assdb = mysql /etc/dovecot-mysql.conf dovecot-mysql.conf : db_host = localhost db_unix_socket = /var/lib/mysql/mysql.sock #db_port = 3306 db = vmail db_user = vmail db_passdb = temp password_query = SELECT 'test' as password from mailbox vmail.sql: create database vmail; use vmail; grant insert,select,update,delete on vmail.* to 'vmail'@'localhost' identified by 'temp'; CREATE TABLE mailbox ( user varchar(20) not null, domain varchar(30) not null, password varchar(20) not null, status char, PRIMARY KEY (user,domain) ); insert into mailbox values('someone', 'domain.org', 'secret', 'Y');

[Dovecot] Dieing?
by Matt Juszczak 07 Aug '05

07 Aug '05

Our dovecot process died out of no where today, with no sign of reasons why. I'm running a beta from a few weeks ago of 1.0 ... are there any security vulns I should know about that might have caused this crash (someone trying something?) Thanks, Regards, Matt
