[Dovecot] Feature Requests
by Jonathan Vanasco 16 Aug '05

16 Aug '05

I put them on the wiki page, but I'm not sure if they're read often or whatever. a - Sqlite support I know its been talked about, but it wasn't on the request/todo page until i threw it on there, so i wanted chime in for it as well b - User configurable ports ports are hardcoded in the c source file. it would be nice if these were the defaults, and could be overwritten on the configure file. this way we can run dovecot to test on the same machine as an active imap server, or just have more control over how we run it

[Dovecot] Wrong dates in Outlook
by Alexander Tamm 16 Aug '05

16 Aug '05

Hello, We're migrating from Ipswitch Imail to Dovecot. There seems to be a problem with Outlook after converting the emails with mb2md and whole bunch of perl scripts to correct all the idiotic mistakes that Imail has made. Outlook will display the date and time of the conversion as the date of the message, rather than using the Date: header. The same does not occur in Thunderbird or Horde/IMP. Any ideas? Alex

Timo, Test-80, running on our production IMAP server. Setup: Solaris 9, compiled with gcc 4.0.1, mbox format, configured like so: VERSION=test80 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl --with-rawlog --enable-debug > configure.out Still seeing occasional assert messages in the syslog: IMAP(username): file mbox-sync-update.c: line 442 (mbox_sync_update_header_from): assertion failed: (ctx->mail.uid == 0 || ctx->mail.uid_broken || ctx->mail.uid == mail->uid) How do I give you useful debug info? Run the offending mailbox thru mboxcrypt.pl, try to reproduce with the mailbox, send the mailbox in? Otherwise test-80 is working great... Jeff Earickson Colby College

[Dovecot] Dovecot crashing

Hi all, 1.0-test76 is crashing about every two weeks. Got this in the log file: pid 76217 (dovecot-auth), uid 0: exited on signal 6 (core dumped) pid 61724 (dovecot-auth), uid 0: exited on signal 6 (core dumped) pid 52961 (dovecot-auth), uid 0: exited on signal 6 (core dumped) pid 81257 (dovecot-auth), uid 0: exited on signal 6 (core dumped) Also a bunch of these around the same time... arplookup 123.456.227.254 failed: host is not on local network arplookup 123.456.227.254 failed: host is not on local network arplookup 123.456.227.254 failed: host is not on local network arplookup 123.456.227.254 failed: host is not on local network arplookup 123.456.227.254 failed: host is not on local network (I changed the first two octets). Anyway, it seems that dovecot is crashing. A simple restart brings it back up. Its odd that it would work for a while and then crash, is there some kind of remote exploit causing it to crash? It says core dumped, but I'm not sure where it would put the core. Also, all of our stuff is LDAP. We dont talk to local passwd files at all. Is there a way I can run the dovecot-auth process as non root? I know there's an option in the config but i tried it and it did not seem to want to restart (the process). Thanks, Matt

[Dovecot] mysql authentication
by Justin Finkelstein 15 Aug '05

15 Aug '05

I've just managed to get dovecot to install on one of our FreeBSD 5.4 servers, using the ports collection. I've set up dovecot to query the mysql database I'm using, and the query I'm using is: SELECT clear AS password FROM users LEFT JOIN domains ON domains.domain_id = users.domain_id WHERE domain="%d" AND username="%d" AND users.enabled = 1 AND domains.enabled = 1 If I perform this query by hand, I get a single row with the field 'password' which contains the password I'm using the perform my intial test. However, dovecot won't authenticate, and returns this error: dovecot-auth: mysql(justin(a)redwiredesign.co.uk): Password mismatch Is there a way that I can see how dovecot's doing the comparison? I have set the following in dovecot.conf: auth_verbose = yes auth_debug = yes I've read the wiki on raw logging, but I don't know: (a) how to enable this through the port (b) whether this is even applicable as apparently all it logs is the imap traffic.

[Dovecot] Assertion failure in mail-index-transaction.c

This just started happening with the current CVS version (2005-07-23). The "user" is a monitoring tool that we use called Sitescope.

[Dovecot] Documentation
by Enrique 15 Aug '05

15 Aug '05

Hello, I have added a few questions and answers to the wiki, about stuff that caused me long hunts when trying to set up dovecot with maildir storage. Some of it I have gleaned from the source. Some of it is actually already documented, but I had not been able to spot it when I needed it. At the time of writing I had a particular advantage: I did not know, or had mostly forgotten, the peculiarities of the imap protocol. I say 'advantage', because I think that when writing documentation it is important, yet difficult, to see things from the perspective of a user that is quite ignorant, although not stupid. These need the documentation most, and they are in majority. (Some will say the "stupid" ones are in majority, but writing for them is almost futile anyway. Anyway, I doubt they are a majority; average intelligence is adequate for all normal tasks. What we often judge and condemn as "stupidity" is most often the result of a different perspective that _we_ are too limited to understand.) Since I am not yet too spoiled, and yet recently had my hands (or rather my eyes) in the source, this may be a golden opportunity to produce some more documentation. I therefore urge you to suggest what I should look at and write about. Do you have any ideas about how the documentation should be organized? some questions are not strictly dovecot or even imap questions, yet they arise quite naturally for an administrator that is migrating to dovecot or to imap in general. The existing migration documentation was not as usefull to me as it could have been because I was both migrating to imap from a non-imap solutions, and from mbox to maildir, both at the same time. That placed me in a particularly "ignorant" position. It is quite likely that much of what I write is not exactly true. I have suggested procmail as a delivery agent for maildir stores, because it is the only one I know about at the moment. I just occurred to me that I have not even checked if /bin/mail (on GNU/Linux systems) can do it. Any ideas? I have not (yet) found out anything about the CONTROL= part of the mail environment. Should I write something about it? Is it usefull for system administrators to know about it? What is it? Regards -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/

[Dovecot] Binc IMAP "IMAPdir" style layout
by Martin Lucina 15 Aug '05

15 Aug '05

Hi, I'm in the process of migrating several years worth of mail to be accessible via an IMAP server. Some time ago, I evaluated both Binc IMAP and Dovecot and found Dovecot to be much faster on large folders, which is quite important to me. One thing I did not however manage to determine from the documentation on namespaces is whether or not it is possible to implement what Binc IMAP calls an "IMAPdir" style layout. IMAPdir lets me layout mailboxes in the filesystem like so: $HOME/ Maildir/ <---- users mail goes here Mail/ <---- IMAP root INBOX -> ../Maildir/ <---- (symlink) folder/ <---- some other mailbox in Maildir format folder.subfolder/ <---- '.' is the hierarchy separator folder.subfolder-2/ other-folder/ So IMAP clients subscribe to 'INBOX' and 'folder' and 'folder/subfolder' respectively. This gives me two features that I want: 1) The ability to easily access all my mail using a command line Maildir capable client such as nail, for when I'm connection over a super-slow SSH over GPRS connection. Also, I can actually see my folders (and their subfolders) without having to look for Maildir++ style names with 'ls -a' (e.g. Maildir/.subfolder/). 2) Mail folders are organized logically, unlike the standard Maildir++ layout where everything is a subfolder of 'INBOX', which strikes me as stupid. Is such a thing possible with Dovecot? Any help would be much appreciated. Thanks, -mato

[Dovecot] IMAP can't read inbox: istream_raw_mbox_get_body_size assertion failed
by Paul Schreiber 15 Aug '05

Yesterday, I upgraded my debian packages from 0.99.14 to 0.99.20050712-2. IMAP service has not been reliable since, and I was seeing crashes with one user.

[Dovecot] Authentication based on client host
by Sebastjan Trepca 15 Aug '05

15 Aug '05

Hi, I am wondering if it's possible to authenticate users that come from specific IP differently then other users. I will be authenticating them by postgresql so something like this would be very useful: password_query = SELECT password from get_user('%username','%host') Is that possible? Can it be done any other way? Thanks, Sebastjan

[Dovecot] hangs on dovecot test77, mutt
by Tzafrir Cohen 15 Aug '05

15 Aug '05

Hi My toy mail server runs dovecot. My client is mutt, which I use normally use a a remote screen session. I normally connect to imap locally: account-hook imap://localhost/ 'set tunnel="/usr/local/bin/imap-local"' After a long frustration from the new mail notification in 0.99, I have decided to bite the bullet and try the -test series. Ever since I have not had stable mutt sessions. Occasionally mutt hangs on the imap connection. Usually when openning a new mailbox. But sometimes even when closing an existing mailbox. Occasionally mutt will even crash (which is annoying, but certainly not a bug of dovecot). How do I debug this? -- Tzafrir Cohen | tzafrir(a)jbr.cohens.org.il | VIM is http://tzafrir.org.il | | a Mutt's tzafrir(a)cohens.org.il | | best ICQ# 16849755 | | friend

[Dovecot] dovecot update ?

Hi list Im currently run debian sarge / testing. I upgraded my dovecot this morning on my mail server this morning, and my dovecot stopped working for my mail users email clients. I told debconf to replace the dovecot.conf (Baring in mind I saved my conf file).

It was only once I realised that when I copied and renamed my .subscription file to subscription, did it all work. Obviously the mistake was on myside but telling debconf to over write the conf file, but I find it a bit weid that when on killing dovecot and then restarting the with the old conf file, it still did not work. To be honest, im a bit lost as to how im going to rectify this, but I know that I want to upgrade my packages. If you can help in anyway, it would be most appreciated.

[Dovecot] Problem with dovecot and system crashing
by Colin Kingsbury 14 Aug '05

14 Aug '05

Hi all, I am running dovecot on a linux server (FC3) in conjunction with Sendmail. My configuration is quite vanilla and I am having the following problem: occasionally (once every 3-10 days) the dovecot server will become unresponsive and attempting to access mail via pop3 will produce an error message on the client side. As best as I can tell, the dovecot process dies because if I restart it with /sbin/service dovecot restart I get [failed] on the stop and [ok] on the start. Now, here's the interesting part: within 5 minutes of this happening, the whole machine becomes completely unresponsive and requires a power-cycle to restart it. In between dovecot dying and the server going down, the other applications (apache, mysql) continue to run. Naturally, there are no messages in the syslog or the maillog and it is set to log all messages of info or higher. Any suggestions on how to attack this would be greatly appreciated. Best, -cwk.

[Dovecot] Mailbox written with normalized headers
by Kenneth Porter 14 Aug '05

14 Aug '05

Over on the SpamAssassin list someone noted that some spam generators add leading spaces to the subject line, but it was impossible to detect this when using Dovecot for POP3 service. Some quick testing shows that dovecot-0.99.13-4.FC2 writes the mailbox back with the extra spaces in the header squeezed out. I think Dovecot should avoid reformatting headers any more than necessary to avoid interfering with spam detectors.

Hi, 0.99 is running nicely on my sarges, but I need pop3_uidl_format = %f for Courier compatibility. I can't find any debs more recent than test22 of over a year ago (those are at http://src.braincells.com/dovecot-test/) Even though google turns up http://hemma.tobbe.nu/debian/mini-dinstall/incoming/dovecot_1.0.test46-1_i3… searching for dovecot on packages.debian.org (any distribution or source) only yields 0.99.14 and 0.99.20050712. I know Jaldhar called for vounteers to take over, but I don't feel qualified... but I've managed to do away with all non-deb installations, so if I have to I'll make a .deb myself, is there maybe an already-written script to do that with dovecot? Thanks for suggestions.

[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.

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.
