[Dovecot] Internal error during expunge
by Tim Jakobsen 19 Jan '04

19 Jan '04

Hi, I'm using dovecot-0.99.10.4_1 on Freebsd. CPU architecture is i386. When ever I try to move messages og delete dem i get an internal error. Below I've tried to show what dovecot says. Mail gets stored using mbox format. After giving the internal error you kan try to expunge the mail again and it works without error. Any suggestions or ideas as to what could be wrong? is it a bug? A003 STORE 1 +FLAGS (\Deleted) * 1 FETCH (FLAGS (\Deleted \Seen)) A003 OK Store completed. A004 expunge imap(foo): Error: Error indexing mbox file /home/foo/Mail/INBOX.Drafts: LF not found where expected A004 NO Internal error [2004-01-14 14:08:13] Tia. -- Regards, Tim

[Dovecot] Certificate Authority-signed certs in dovecot?
by Benjamin J. Weiss 19 Jan '04

19 Jan '04

Hi! Sorry if this has been covered. I've just started using dovecot and I've searched via google and I've downloaded the maillist archives, but I haven't found a solution. I'm using Fedora Core 1, with dovecot-0.99.10-6. When I'm at work, I access my home mail server using Outlook Express (I know, I know, but it's the only client I'm allowed to use at work). Now, I'm able to get to my email, but I get a warning popup box each time I connect to the server, that the authenticity of the certificate can't be verified. I'm assuming that that's because I am using a self-signed certificate. Now, I'm also using postfix, and it allows for me creating my own CA certificate, and using it to sign my own certificates. The /etc/postfix/main.cf entries are: smtpd_tls_key_file = /etc/postfix/newreq.pem smtpd_tls_cert_file = /etc/postfix/newcert.pem smtpd_tls_CAfile = /etc/postfix/cacert.pem but while I see the following two lines in /etc/dovecot.conf: ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem I don't see how to specify my CA cert. I'm pretty much a noob when it comes to openssl, but I've been able to follow directions to get the TLS working in both postfix and dovecot. I just want to get rid of that annoying message. I figure that there's a way to sign my dovecot certs with the ca cert I've already created for postfix, and tell dovecot about it somehow. Has anybody done this? Thanks! Ben

[Dovecot] Outlook 2002 sp-2 and initial connection after OS reboot
by David Crisp 14 Jan '04

14 Jan '04

I have a strange problem that I have been experienceing with dovecot: Dovecot version : 0.99.10.4-1 Using IMAP: When I restart the OS (windows XP) and open up Outlook 2002 SP2 I don't automatically get my IMAP folders on the DOVECOT imap server. (the one on the uw_imap server open up straight away) When I click on inbox I cam given a message saying : unable to connect to imap folders When highlight the inbox and go to "file" "connect to <imap server>" I get the error again.. "unable to connect to imap folders" If I just leave Outlook open for a while the folders mysteriously connect themselves. Has anybody seen this before and does anybody have any ideas on what to do to fix things. Is this an Outlook problem or a dovecot problem? I searched the archives and theres been nothing recently about this kind of problem. I need to get this system running in production very soon. --- David Crisp IT Systems Administrator WSL Consultants Pty Ltd dcrisp(a)wsl.com.au 2-8 Harvey Street Richmond Vic 3121 Australia Phone: +61 3 9429 4666 Fax: +61 3 9429 2294 Web: www.wsl.com.au ------------------------------------------------------------------------------ WSL Consultants Pty Ltd www.wsl.com.au Head Office: 2-8 Harvey Street, Richmond VIC 3121 Ph: (03) 9429 4666 Fax: (03) 9429 2294 Bendigo Office: Gate 6, Sharon Street La Trobe University, Bendigo PO Box 106, Strathdale VIC 3550 Ph: (03) 5444 7890 Fax: (03) 5444 7895 This message is intended solely for the individual(s) and entity(s) addressed.

[Dovecot] imap sync
by Arnold Cano 12 Jan '04

12 Jan '04

Has anyone used any of those utilities that synchronize imap email from one server to another? I tried using imapsync-1.65 and it reports that dovecot has no namespace support and requires me to manually enter the separator? Would this be "."? or ".INBOX"? or "/"? Thanks, Arnold

[Dovecot] Maildir and Mail at the same time.
by Dan Slowik 08 Jan '04

08 Jan '04

I am trying to use Maildir format for My inbox and be able to save the messages in ~/Mail. Problem is dovecot only show the Maildir mailboxes not the ~/Mail formatted boxes. How can I get this to work? If I use namespace or something how would this be configured I cannot find much documentation that explains it well enough. example: what would I have to configure in dovecot.conf or otherwise? I would like to see this. INBOX -- sent | drafts |- (Maildir format from ~/Maildir) trash -- sent -- recieved | deamons |- (mbox format from ~/Mail) unixfolk -- Currently I can only see the ~/Maildir like so. INBOX -- sent | drafts |- (Maildir format from ~/Maildir) trash -- Thanks __________________________________ Do you Yahoo!? Find out what made the Top Yahoo!

[Dovecot] SSL and STARTTLS
by Mark E. Mallett 08 Jan '04

08 Jan '04

I wanted to enable SSL on some alternate ports so that a limited number of people could try SSL access. But doing so enabled STARTTLS in IMAP, so that all IMAP users got surprised (at least those whose clients attempted to use it automatically). e.g.: # IP or host address where to listen in for SSL connections. Defaults # to above non-SSL equilevants if not specified. imaps_listen = *:xxxx pop3s_listen = *:yyyy # Disable SSL/TLS support. ssl_disable = no Is there a way to enable imaps/pop3s without enabling STARTTLS? (If so it's probably blindingly obvious and I am missing it..) Yours, mm

[Dovecot] folders not subscribed
by Jerry Chiu 08 Jan '04

08 Jan '04

when migrated from courier-imap, I found that all the sub-folders are not subscribed, I have to manually subscribe all of them. It is not very practical since many of my users have complicated folder structure... Is it possible that the dovecot server auto-subscribe all sub-folders if the ".subscriptions" is not present in the Maildir? Thanks, Jerry

[Dovecot] Problem with Eudora
by Scott Klein 06 Jan '04

06 Jan '04

I'm trying to get Dovecot (dovecot-0.99.10-6) to work with Eudora (6.0 mac/win) and am having a real problem when I try to enable SSL, either TLS or alternate-port SSL. Although my other mail clients, mail.app, imp, etc. work just fine, either version of Eudora craps out when trying to connect via TLS or SSL -- on the mac I get the error Could not get mailbox list. 20 [CLOSED] IMAP connection broken (command) On the PC I get something similar. Sometimes, on the mac, I don't get the [CLOSED] part I get Unable to get the required mailbox list from the server I've tried the "esoteric settings" trick (setting "user plain text password" in the IMAP panel) but that doesn't work. Everything works fine when I turn SSL off. I'm kind of at my wit's end. Has anybody experienced this? Have I not read TFM? Hope y'all can help. Best, Scott Klein

[Dovecot] RE: Compile problem
by Alex S Moore 06 Jan '04

06 Jan '04

I am a package maintainer for the Solaris community site known as CSW or blastwave.org. A CSW user requested a dovecot package, so I am attempting to build the package. I downloaded 0.99.10.4 earlier this month and it compiles just fine on my test machine. I went to our CSW build machines to build a version that I can distribute. I got the latest CVS version and used the same environment variables and configure options as the build on my test machine. In src/lib-storage I get the following compile error. I do not have proxy-mail-storage.c on my test machine from the earlier download, so I hope this is a problem that you can easily fix. The environment is Sun SPARC on Solaris 8. I am using the Sun compiler which seems to work fine for this software.

[Dovecot] DIGEST-MD5 Authentication
by Dominic Marks 06 Jan '04

06 Jan '04

Hello, I am confused by a problem I am having getting Dovecot to authenticate users with DIGEST-MD5. I am receiving the error message, "Unexpected service type in digest-uri". (cvs: mech-digest-md5.c, line 407) From an examination of the code it is clear that a check is performed to see if the first component of a the digest-uri triplet is the string "imap". The service type surely is IMAP, and from what I can gather of the expected format of the digest-uri triplet from the comments in the code it should be the first component. Is this just a case of inverted logic or am I mistaken ? Thanks, -- Dominic <dom at wirespeed.org.uk>

[Dovecot] logfile errors

Ive recently installed dovecot as a replacement for my uw-imap server. Ive noticed a few error messages in the log file, although in operation ive seen no problems from my mail client.

Is there any explanation to what they mean or are they insignificant enough to ignore? thanks Simon

What does the logfile say? If you're using syslog, dovecot uses the LOG_MAIL facility I think, so you might want to check whatever log that prints to. I had a couple problems like this, and it was because I had set up authentication incorrectly, so you may want to double check that. Best, Tim M.

[Dovecot] Fatal: USER environment missing
by Evert Mouw 29 Dec '03

29 Dec '03

I have some trouble installing dovecot, and maybe someone can help me. I have compiled dovecot on a Slackware Linux 9.0 running on a i586, and the imap program works OK (I tested it using the method described in the error reporting document). The make install procedure didn't create a correct /etc/rc.d/rc.dovecot file. I have created a dovecot user and group manually. Running just "dovecot" from the command line does not give any errors, but dovecot terminates and doesn't whow up with ps x. So I tried to start it from inetd, but starting dovecot from inetd results in something like "port 143 already in use", so I decided to start /usr/local/libexec/dovecot/imap directly from inetd, which results in Fatal: USER environment missing, even when using root for everyting (and the environment variable USER really exists). I fiddled with various options in the dovecot.conf file without any results. Now I'm stuck; the INSTALL document actually is a BUILD document and I can't find anything about post installation :-( Someone any ideas? Regards Evert Mouw

[Dovecot] Bugfix for use with "Opera mail" and "AnalogX"
by Gerhard Muntingh 24 Dec '03

24 Dec '03

Dear developers, [ Please CC me as I'm not subscribed to this list. ] In src/pop3-login/client.c: void client_send_line(struct pop3_client *client, const char *line) { o_stream_send_str(client->output, line); o_stream_send(client->output, "\r\n", 2); } Called as 'client_send_line(client "+OK dovecot");'. This function sends two packets to the client. It appears Opera mail and AnalogX proxy recognise the 1st packet as a complete welcome and send their "USER " command after receiving it. They then receive the newline in the next packet and get confused. This is very probably a bug in those two programs, but it would still be great if it could be fixed in the dovecot source. My personal fix involved a buffer on the stack (char tmp[LENGTH]) and some sanity checks wherein the newline is strcat'ed to the string. That's not very nice, but it works for me. Can someone please fix this? There may even be more pop clients having problems with this. kind regards, Gerhard Muntingh.

[Dovecot] Maildir quotas support in Dovecot and 2 other newbie questions
by Theodore Knab 21 Dec '03

21 Dec '03

I am not familiar with all the features that Dovecot has, but I am familiar with Courier IMAP using Maildir. Does Dovedot have a software based Maildir supporting quota program like Courier IMAP ? Can maildrop be used with Dovecot for quotas ? Courier IMAP has maildrop integrated. - If maildrop support is turned on in Courier IMAP, then a user will get a quota warning mail message each time they login to their account and are over the specified amount. Is there a recommended MTA to be used with the DoveCot IMAP server ? -- ------------------------------------------ Ted Knab Chester, MD 21619 ------------------------------------------ 35570707f6274702478656021626f6c6964796f6e602f66602478656 02e6164796f6e60237471647560216e6460276c6f62616c60257e696 4797e2a0

[Dovecot] multiple auth= statements
by Stephan van Beerschoten 16 Dec '03

16 Dec '03

I'm new to dovecot and it's configurations. Reading the config file, I have a question regarding having multiple auth= lines in there. Is this some sort of a pass-through or fail-through system of authentications like where if a user is not authenticated using 'pam', then the second method is tried (which might be sql or plain passwd-txt) ? Am I assuming the right thing here ? I have system-users, but am planning to migrate the majority of those users to a virtual_mailbox system (using postfix) where they have no more system-users . I just want to be sure this will work. If anybody has setup a system with postfix and virtual mailboxes in combination with dovecot, and wants to swap stories and setups, I'd be grateful :) /Stephan -- Stephan van Beerschoten [KeyID: 0x08F12864] "If you are adminstering UNIX systems and don't master tools such as make, shell, and perl, then you are working too hard." -- Wietse Venema.

[Dovecot] Always 'new mail' false notifications?
by Stephan van Beerschoten 16 Dec '03

16 Dec '03

Hi, I just yesterday played around and installed dovecot. I like it a lot (except for the lack of mysql support), but I have one issue I can't seem to fix. I am using mutt as my mailclient and mutt will alert me whenever new mail has arrived in any mailfolder I have configured. The thing is, that mutt continously signals me of new mail in all my folders, when in reality nothing has entered there. Does this sound familiar to anyone ? All I can think of, is that something is happening with modification timestamps of my mailboxes which signals the new mail flag, but I don't know what causes it. A small description of my setup: One server running dovecot. I access mail locally via IMAP, but can also access the spoolfiles and mailfolders directly. I'm the only one with shell access. Procmail filters mail and delivers it to my mailfolders in ~/Mail. Any ideas ? -- Stephan van Beerschoten [KeyID: 0x08F12864] "To err is human, to forgive is Not Company Policy"

[Dovecot] Authenting in Linuxconf format
by Marc Perkel 09 Dec '03

09 Dec '03

I have an existing email system and I'm trying to addapt dovecot into it. It uses the linuxconf virtual email format. The way it is set up is there there are multiple passwd/shadow files - one for eact domain. They are in standard format. The names of these files are: /etc/vmail/passwd.domain.com /etc/vmail/shadow.domain.com I tried this: auth_userdb = passwd-file /etc/vmail/passwd.%d auth_passdb = passwd-file /etc/vmail/shadow.%d but - it didn't expand the %d So - is this going to work? If not - how do you do virtual domains? The documentation is less than complete on this.

[Dovecot] Folder names
by Keith Edmunds 09 Dec '03

09 Dec '03

I'm not sure offhand exactly which version of Dovecot I'm running - it doesn't seem to have a -V switch. Anyway, I created a folder which had periods in the name. There was no problem with that, but MUAs now report that folder as a hierarchy. For example: customers | +-customername.com | +-another.customer.com has become: customers | +-customername | | | +-com | +-another | +-customer | +-com Now the obvious answer is "don't do that". However, should Dovecot either a) refuse to create a folder with an embedded period in the name or 2) manage (somehow) the fact that not all periods represent hierarchical delimiters? Keith PS Damn fine software, Dovecot

[Dovecot] subscriptions list destroyed
by kalle-e＠medelklassen.com 04 Dec '03

04 Dec '03

What could be the reason that the subscribed folders list becomes messed up? If i do this: $ rm ~/.maildir/.subscriptions $ evolution [subscribe to everything, exit program] $ cat ~/.maildir/.subscriptions debian sers va $ (or some other random text which seems to come from parts of the folder list) This makes Mozilla Mail go crazy. Evolution and Gnus work OK since they seem to have their own list, but switching back and forth between Evolution and Gnus makes Evolution forget the list. I don't think I had this problem before. I used mbox then.

[Dovecot] Severe pop3 incompatibility report
by Kadlecsik Jozsi 04 Dec '03

04 Dec '03

Hello, According to our experiences, most recent dovecot incompatible with eudora pop3 client - eudora (5.1, 6), pop3, 'leave on server' enabled: the clients receive the full inbox *every time* they check the inbox on the server. [Users using other MUAs experienced the same once, at switching from uw-pop3d/imapd to dovecot.] That is absolutely devastating, especially for home users behind a modem line. We spent a full week with trying to find a workaround with eudora: no avail. The only solution remained was to revert back to uw-pop3d. :-( Best wishes, Jozsef Kadlecsik -- E-mail : kadlec(a)sunserv.kfki.hu, kadlec(a)blackhole.kfki.hu PGP key: http://www.kfki.hu/~kadlec/pgp_public_key.txt Address: KFKI Research Institute for Particle and Nuclear Physics H-1525 Budapest 114, POB. 49, Hungary

[Dovecot] Maildir Sub folder was not fetch as start

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I'm new to dovecot and have been using sinces Fedora Core 1 release. My setup is as below. Server : dovecot Imap Maildir (was from courier-imap) (v 0.99.10 from fedora) Client : Mozilla mail 1.5 (rpm from www.mozilla.org with some additional patch to work with fedora) The Problem is like this. When the Maildir is in this format .INBOX.Foldername And Subfolder is .INBOX.Foldername.Subfolder (courier-imap don't use this file names, I rename it personally) So that the client can access without any changes. When using this Folder format I've no problem on fetching the subfolder. They all load nicely when mozilla mail start. So One day I've change My Maildir into this format .INBOX.Foldername ---> .Foldername .INBOX.Foldername.Subfolder ---> .Foldername.Subfolder Something weird happen... My foldername is System Log The subfolder just don't load it correctly *ON THE FIRST TIME of access* on mozilla I'll have to click on the mail root (as a refresh) to make sure it fetch all the folder.

[Dovecot] pop3-login process leakage
by Clive Jones 28 Nov '03

28 Nov '03

Hi, I've recently deployed dovecot on our servers, to replace courier-imapd. I'm delighted with its features and performance, but there's a major problem - it's leaking pop3-login processes. We have about 60 client machines, each collecting mail once every two minutes. In this configuration, the number of pop3-login processes increases by about ten an hour - apparently without bound. My workaround is to increase the open files rlimit, and the kernel overall limit on open files. This postpones disaster for long enough that killing and restarting dovecot nightly avoids problems. A possibly related problem is that about 1% of attempted POP3 logins fail. At the server, all I see is a syslog entry like this: Nov 3 22:17:21 greenwich pop3-login: Disconnected: Inactivity [10.76.30.246] At the client, there is a long (about 60-second) timeout. Then the client automatically retries, and generally succeeds. There are *not* exactly as many such disconnects as there are stray pop3-login processes - I counted roughly 230 inactivity disconnects in the time it took for 190 stray processes to accumulate. We are running dovecot 0.99.10 on OpenBSD 3.2 . The configuration is fairly normal, except that we are using a custom userdb and passdb (compiled as shared objects): auth_userdb = passwd8 auth_passdb = smb passwd8 is just userdb-passwd.c with a trivial tweak to truncate presented user names to eight characters. smb is an shim that delegates authentication to smbclient, to check passwords against NT domain controllers. I've placed the source code for these two modules in: http://www.nsict.org/~clive/misc/dovecot-2003-11-04/ ...along with my dovecot.conf, and a file that illustrates the growth in the number of pop3-login processes over time. So far as I'm aware, those modules are loaded by the dovecot-auth process, not the pop3-login processes, and are therefore unlikely to be the problem? The client machines are LAN-connected, and running a mixture of Outlook (2000/XP) and Outlook Express (5.5 and 6). There are also a couple of people using Mozilla. Most are collecting e-mail via POP3, a few via IMAP. This issue didn't show up under beta-test loading before I deployed dovecot. Since it seems only to be exhibited (or, at least, noticeably exhibited) under live load, it's very hard for me to diagnose things further without disrupting service. I'd be very grateful if anyone could suggest what might be wrong. Regards, --Clive.

[Dovecot] Pid file?
by Clive Jones 27 Nov '03

27 Nov '03

Is there a way to make Dovecot maintain a pid file? Most daemons put their pid in /var/run/dovecot.pid (or similar) while they are running, then remove it on exit, but I can't find any option to do this in Dovecot. (Of course, if I could work out how on earth to stop Dovecot leaking processes, I wouldn't be looking for a simpler way to keep bringing the daemon down and restarting it. (-8 ) Regards, --Clive.

[Dovecot] Incompatibility with eudora
by Kadlecsik Jozsi 27 Nov '03

27 Nov '03

Hello, We installed dovecot-0.99.10.2 on Monday and upgraded to dovecot-0.99.10.4 today, but our eudora users still are very unhappy: old undeleted mail messages are donwloaded every time they use our server. Looking into the source code, we found that dovecot knows about the following status flags: A: answered F: flagged (?) T: draft (?) R: seen (read) D: deleted However, it does not know and ignore the O flag. According to IETF (http://www.ietf.org/internet-drafts/draft-palme-mailext-headers-08.txt) the following flags are valid (I know, it's a draft and not RFC): U: message is not downloaded and not deleted R: message is read or downloaded O: message is old but not deleted D: to be deleted N: new "Combinations of these characters can occur, such as "Status: OR" to indicate that a message is downloaded but not deleted." The old mails of our eudora users contain exactly this flag combination: Status: RO Could the compatibility problem somehow be fixed? Currently our system is pretty unusable for the users :-( Thank you and best regards, Jozsef -- E-mail : kadlec(a)sunserv.kfki.hu, kadlec(a)blackhole.kfki.hu PGP key: http://www.kfki.hu/~kadlec/pgp_public_key.txt Address: KFKI Research Institute for Particle and Nuclear Physics H-1525 Budapest 114, POB. 49, Hungary

[Dovecot] a couple more tidbits on the conversion process
by Eric S. Johansson 26 Nov '03

26 Nov '03

a couple of things that really helped me when converting from mbox to maildir. First is to see how simple procmail changes could be. in your /etc/procmailrc file, just add the following. MAILDIR=$HOME/Maildir/ # Make sure this directory exists! DEFAULT=$MAILDIR if you're using per user procmail files, the exact same two lines will also work to ensure proper delivery. if you're anything like me with 200 plus mailboxes, the following utility is really superb at doing the conversion all at once. Granted, I had to wait awhile to convert the GB+ of e-mail but I had other things to do and not getting interrupted every few minutes made the time reasonably productive. :-) http://batleth.sapienti-sat.org/projects/mb2md/ I was getting an error about some sort of illegal character sequence but the mail seems to have converted fine. I think the next thing to do is create a new partition for home and make it ReiserFS. ---eric -- Speech recognition in use. Incorrect endings, words, and case is closer than it appears

[Dovecot] did the conversion and something broke

figures. Converted over to maildir today. Procmail is a piece of cake once I managed to pride out of its cold dead fingers the essential tiny bit of documentation I needed. But I'm having a problem with my nested directories. I have a directory called incoming sort my incoming mail. The conversion utility created a bunch of files called incoming.<stuff> and 1 file is visible incoming/pound. However, if I try to subscribe to anything else I get: the current command did not succeed. The mail server responded: Invalid mailbox name: incoming/ATMoB and this is how it set up.

[Dovecot] IMAP subscribe/unsubscribe broken in 0.99.10.2

IMAP subscribe/unsubscribe is broken in 0.99.10.2 (and earlier releases), specifically subsfile_set_subscribed(), where the logic is all wrong. I tried just copying over the latest subscription-file.c but it has dependencies on some file locking/dotlocking stuff that 0.99.10.2 doesn't have. Timo, would it be possible to incorporate the latest subscription-file.c into 0.99.10.3 (whenever that will be)? Matt

I had trouble with an instantssl cert, and found that what I needed to do was to also include all the certs up the chain in the .pem file, in a certain order, to keep the client from complaining about an invalid certificate. The first certificate in the pem file should be the the server certificate, followed by its chain starting from the root certificate down.

[Dovecot] mbox format

I wish to know some implementation details about mbox. When you you mbox format in IMAP, are you doing to keep the same message UID across IMAP session if you know that any other program can modify the mailbox as it wants, for example, two messages can be exchanged. In this case, will the UID kept the same ? If they keep their UID, how do you identify the messages ? Thanks, -- DINH V. Hoa, etPan! - newsreader, mail user agent -- http://libetpan.sf.net/etpan

[Dovecot] New index / mailbox API
by Timo Sirainen 25 Nov '03

25 Nov '03

Today morning I had an idea how to make indexes more scalable with multiple concurrent writers. As a side effect it also made the locking issues much more simpler. So I thought I'd go and rewrite all the indexing code, it had gotten way too ugly and difficult to understand and maintain. I also thought to separate the index handling completely from mailbox handling. So there would be lib-index and lib-mailbox. lib-storage would then tie them together. Mailbox API still feels somewhat dirty though.. I didn't want it to depend on lib-index and I didn't want to duplicate any lib-index functionality in it to avoid uselessly allocating memory, so I can't reference to mails directly with their sequence number or UID. So I'm passing (void *id, size_t id_len) around - with maildir that would be the filename and with mbox it would be current offset in file. Suggestions welcome about both APIs. Some of the changes in indexes and it's API: - "modify log" -> "transaction log" which was the big change. All flag updates and expunges are first written to transaction log and only when committing it they will be moved into the main index. The transaction writes require the file locked for only very short time, so with lots of concurrent writers it means that several sessions could have written their wanted changes to log file, but they're all blocking on getting them moved into main index. When one session finally gets a lock in the main lock file, it writes everyone's changes into it. If lock can't be acquired in a second or so, the main index will be rewritten into temp file and rename()d over. This means that we can have tons of sessions reading and writing to same shared index file and no session can block others from reading or writing. Currently yoou could easily block changes for a very long time with eg. FETCH 1:* BODY.PEEK[] and reading it 1 bytes/sec. - mail_index will be a class interface, so it's implementation can be changed at runtime. In-memory indexing is going to be a totally different implementation this time with better memory usage. Could be useful for optimizing some special cases as well. - You'll get "views" into mailbox. A view will take care of keeping sequences synchronized according to what each client session thinks they are. Currently lib-storage does that in kind of ugly way. Hopefully this means that we can get rid of sequence parsing in lib-storage completely and move it into imap-only code. - You don't directly manipulate with locks and there's no rules of in which order you have to do something. You get views and transactions and use them. - You can have multiple views and transactions, so one opened index could be used to handle multiple client sessions. I'm not sure if that will ever be useful though :) - Error correction will be done automatically this time. Whenever some error is noticed, it will be fixed immediately and unless it changes syncing state, it doesn't force client to disconnect. Also it hopefully will be possible to change from disk-indexing to memory-indexing on the fly in case you run out of disk space. - I'm trying to get it NFS-safe.. - mail-cache that I recently rewrote doesn't change. The bad thing is that it seems to be broken in some way and probably needs rewriting anyway.. And I'm not sure if the problem is just in the code, or if the design itself is somehow broken with it. I'm fearing that memory doesn't somehow keep up with changes by other sessions, since we're not locking cache file for reading..

[Dovecot] deliver mail with postfix to dovecot for mailinglists
by Sven Kirmess 25 Nov '03

25 Nov '03

This is a bit off topic on that list. But the question is required because of a limitation of dovecot. It cannot have shared mailboxes into which one would collect mailing list mails. I assume one has already solved that problem and therefore ask this question on that list. I try to do the following: I would like to setup an alias dovecot(a)kzone.ch and subscribe this alias to the dovecot mailing list. Then I would like to create an alias to run maildrop with the correct parameter to put it into the directory ~ski/Maildir/.dovecot/. Of course, there is no user dovecot on my system and if there would be one she couldn't write to a directory owned by me. Is there a trick to do the following: ski -> ~ski/Maildir dovecot -> ~ski/Maildir/.dovecot postfix -> ~ski/Maildir/.postfix Any other idea? Any good documentation on that? Sven

[Dovecot] entourage + dovecot bug?
by Payton 24 Nov '03

24 Nov '03

I have dovecot set up to run IMAP services without SSL (I have tested many other configurations as well, but this reproduces the problem the simplest). When attempting to connect to the imap server using Entourage for OS X on a mac, I receive the following error: Mail could not be received at this time. The server returned the following error . Dovecot reports a successful login and nothing else in the mail log. All other email clients I have tried (mutt, Mail.app) work fine with the IMAP server. I have also tried this on multiple clients with the same results. All this leads me to believe a bug exists in Entourage, however: I also have a Red Hat 7.3 server running qmail and dovecot in nearly the same manner (except that it is using dovecot 0.99.10 and shadow for password authentication, instead of dovecot 0.99.10.2 and ldap password authentication). Entourage (and all other clients) works just fine with this setup. I'm not certain if the problem lies in some tweak between 0.99.10 and 0.99.10.2 or if it is something with the red hat system itself, but I can't find anything. I am using dovecot 0.99.10.2 on a Red Hat 9 system using qmail 1.04 (netqmail) and checking with the latest version (update 10.1.5) of Entourage on Mac OS 10.2.8. Thanks for any help! -Payton

[Dovecot] IMAP subscribe/unsubscribe broken in 0.99.10.2
by Scott Heavner 23 Nov '03

23 Nov '03

I saw this problem with 0.99.10.2 and had to revert back to 0.99.9.1. As I recall the subscription stuff was not respecting the end-of-line as a field separator. It would just cut the old text and drop the new in it's place. Or it might cut an inappropriate entry that should have been a partial string match. FolderOneOhNine FolderOne FolderThree Trying to delete FolderOne would probably [i didn't save any botched subscription files] result in this OhNine FolderOne FolderThree -scott

[Dovecot] 0.99.10.1 released
by Timo Sirainen 23 Nov '03

23 Nov '03

Since release candidate I added fix for CRLF + partial BODY[] fetching. I hope everything works :) I've been running it with mbox for a while and it seems to work fine. v0.99.10.1 2003-11-10 Timo Sirainen <tss(a)iki.fi> * mbox: \Draft and \Deleted flags used opposite flag chars in X-Status header. We were incompatible with other mbox accessing software. WARNING: Upgrading from previous version doesn't automatically swap the flags, so be careful not to accidentally expunge messages that had their \Draft flag changed to \Deleted. * Configuration file changes: - Whitespace at end of line is stripped, use quotes if you need it - # comments are supported after key=value lines. if you need '#' character, quote the value - Both " and ' quotes are supported. If you need to use them, '\' can be used for escaping. - mbox: COPY into same mailbox didn't work and could have corrupted the mailbox - Using Dovecot without index files would crash after using a while - Partial BODY[header] or BODY[part] fetches were buggy if client requested more data than was available in the header/part. - Partial BODY[...] fetches were buggy with messages that had CRLFs - Some BODY and BODYSTRUCTURE replies missed data for message/rfc822 MIME parts causing clients to break - SORT (SUBJECT) was buggy - Timezone fixes with Date-header

Just found out about Dovecot and it seems to work great. My problem is that it compiles and runs on Redhat just fine. On the other hand it compiles on suse and solaris but will not work. When I start dovecot it silently stops running. No entries in the log or anything. Are there any specific instructions for compiling it on solaris x86 using gcc. Thanks

[Dovecot] SSL and certificate authorities.
by James Tyson 20 Nov '03

20 Nov '03

Hi all. Usually for in-house use and SSL I would just generate a self-signed certificate because most clients either ignore it or only ask the first time the account is configured. In terms of offering the service to our customers is there any value of getting someone like thawte or instantssl to sign a certificate for imaps/pop3s/smtp? Also, is there a configuration directive for dovecot to add the issuers ca bundle similar to apache's SSLCACertificateFile? And thanks for writing such a kick-arse imap server. It blows courier out of the water! --- James Tyson Director, Giant Robot Ltd http://www.giantrobot.co.nz/

[Dovecot] error msgs about missing ssl/tls support
by Kai Vehmanen 18 Nov '03

18 Nov '03

Hi, I've been just testing 0.99.10.2 and had a really hard time getting the new Dovecot to start properly. First I thought it was an error in my old dovecot.conf, but the actual problem turned out to be simply that Dovecot was compiled without SSL/TLS support (I hadn't noticed this), but dovecot.conf on the other hand specified SSL/TLS ports. The error messages might be a bit more informative in this case. Currently I only got this to my logs: --cut-- Nov 18 18:17:00 dovecot: Dovecot starting up Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 pop3-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 dovecot: Login process died too early - shutting down Nov 18 18:17:01 dovecot: child 18482 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18481 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18480 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18479 (login) returned error 89 --cut-- ... and Dovecot would exit. Running Dovecot under gdb would just exit (even with -F), and segfault if ran under strace. So it took a while before I realized that configure had not even detected SSL/TLS... Oh well, not a big thing, but still something to keep in mind. -- http://www.eca.cx Audio software for Linux!

[Dovecot] Children, HasChildren
by Miquel van Smoorenburg 17 Nov '03

17 Nov '03

Hello, I'm using dovecot 0.99.10.2 on a debian box. Mailstore is maildir. If I list the IMAP hierarchy in mutt (debian, 1.5.4+20031024-1) it shows all my plain mailboxes as having subfolders - while none of them have. I straced mutt and this is the IMAP exchange (a bit reformatted for readability): write(6, "a0001 LSUB \"\" \"%\"\r\n", 19) = 19 read(3, " * LSUB () \".\" \"Drafts\" * LSUB () \".\" \"INBOX\" * LSUB () \".\" \"Sent\" * LSUB () \".\" \"Trash\" * LSUB (\\Noselect \\Children) \".\" \"broadband\" * LSUB (\\Noselect \\Children) \".\" \"cistron\" * LSUB (\\Noselect \\Children) \".\" \"debian\" * LSUB (\\Noselect \\Children) \".\" \"ip\" * LSUB (\\Noselect \\Children) \".\" \"lists\" * LSUB (\\Noselect \\Children) \".\" \"prive\" a0001 OK Lsub completed. ", 1024) = 374 Now this is strange - I read RFC3348 and shouldn't \\Children be \\HasChildren, also shouldn't the plain mailboxes (first four) be listed with \\HasNoChildren ? Mike.

[Dovecot] Corrupted index files
by Tomi Hakala 17 Nov '03

17 Nov '03

Hi, I'm playing with Dovecot in a lab environment and got it in state where it crashes on every incoming connection. I moved mail spool from ext2 file system to a ReiserFS on a another disk, mount point changed from /var/vmail to /spool/vmail. After that I managed to open mailbox and I moved about 2000 messages from INBOX to a subfolder. Then I tried to open mailbox with POP3 and it didn't succeed, from that point pop3d and imapd died every time I logged in until I removed all index files by hand. This is what I have in logs. imap-login: Nov 17 13:30:53 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3-login: Nov 17 13:32:04 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3(tomi.hakala(a)xx.fi): Nov 17 13:32:04 Error: Corrupted index file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index: Sequence 1848 not found from binary tree (5398 msgs says header) pop3-login: Nov 17 13:32:12 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3(tomi.hakala(a)xx.fi): Nov 17 13:32:21 Error: Couldn't lock created modify log file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index.log imap(tomi.hakala(a)xx.fi): Nov 17 14:09:32 Error: IndexID mismatch for modify log file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index.log imap(tomi.hakala(a)xx.fi): Nov 17 14:09:33 Panic: file mail-tree-redblack.c: line 187 (rb_left_rotate): assertion failed: (node[x].right != RBNULL) dovecot: Nov 17 14:09:33 Error: child 19984 (imap) killed with signal 6 imap-login: Nov 17 14:27:24 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] imap(tomi.hakala(a)xx.fi): Nov 17 14:27:24 Panic: file mail-tree-redblack.c: line 232 (rb_right_rotate): assertion failed: (node[y].left != RBNULL) dovecot: Nov 17 14:27:24 Error: child 10478 (imap) killed with signal 6 -- Tomi Hakala

[Dovecot] Problem with DIGEST-MD5 authentication and plaintext passwords
by Matthew Reimer 17 Nov '03

17 Nov '03

I wasn't able to get DIGEST-MD5 authentication working with passwords stored as plaintext until I tweaked password_generate() to make it not use the domain portion of user(a)domain.com as the realm. Both evolution and kmail send the email address as the username with no realm; when dovecot tries to convert the username to user + realm, the hash is different and so DIGEST-MD5 authentication fails. Having password_generate() hash user@domain.com::password instead of user:domain.com:password fixes it. I need this to work because I need to support all of PLAIN, CRAM-MD5, and DIGEST-MD5 at the same time. Timo, do you think this is a proper fix, or are kmail and evolution broken? Matt

[Dovecot] dovecot vs cyrus, uw, etc.
by Scott Klein 13 Nov '03

13 Nov '03

I've been doing research on switching our current e-mail server (qpopper, sendmail) to imap. The decision on which server to use is essentially down to Cyrus and Dovecot -- I like Cyrus' approach to a lot of things, but the "blackbox" nature of it makes some niceties like using spamassassin and procmail difficult, or at least counterintuitive. Dovecot seems to play nicer with other apps. I'm a bit concerned with stability, though. Although we don't have a lot of users (about 60) they're all very big e-mail users -- my users rely on their e-mail more than on their phones. We can't afford any downtime, and with our pop3 server, we haven't had any. Does anybody on this list use Dovecot to serve mission critical e-mail to an entire company? What kind of uptime can I expect? Is it genuinely ready for prime time? Has anybody here migrated from a recent release of Cyrus and can compare apples-to-apples?

[Dovecot] PATCH: CRAM-MD5 for Dovecot
by Joshua Goodall 11 Nov '03

11 Nov '03

Hi Timo, Mozilla 1.5 doesn't understand DIGEST-MD5; it only speaks CRAM-MD5 or PLAIN. Maybe other clients have the same problem. My users like Mozilla, so I wrote new code for Dovecot to speak CRAM-MD5, using your mech-digest-md5.c as a reference. Attached diff in two formats i) for current CVS ii) against last release both tested and working with Mozilla and KMail's CRAM-MD5. I don't know if I've caught precisely the coding style you use for Dovecot. I hope so, but I'm unsure if I've used your string and buffer libraries properly. Please enlighten me if you have time. Would you consider including this in the next release?

I'm running Dovecot under PLD GNU/Linux, on two servers. Under kernel 2.4, it works wonderfully. Under 2.6, I get this in the log: Nov 9 21:36:38 polis dovecot: Dovecot starting up Nov 9 21:36:39 polis imap-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis imap-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis pop3-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis pop3-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis dovecot: Login process died too early - shutting down Nov 9 21:36:39 polis dovecot: child 32404 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32405 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32406 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32408 (login) returned error 89 Nov 9 21:36:39 polis pop3-login: fd_send(-1) failed: Broken pipe Any ideas? the setuid32() call is returning EAGAIN, though I have no resource limits on user nobody (nor does it work as a dovecot user).

[Dovecot] openssl decryption failed
by Tom Allison 09 Nov '03

09 Nov '03

I've got dovecot working on imap But when I try to run imaps I get: imap-login: Nove 08 19:11:19 Warning: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac [192.168.1.103] Now I'm not sure if theres any difference here, but I don't have string for 'login = imaps' or 'login = pop3s' to match with my protocols string I also don't have any specific imaps_listen interface defined, but since there's something in the logs, I assume that this is not a problem. SETUP fluffy:~ # egrep "^\w" /usr/local/etc/dovecot.conf base_dir = /var/run/dovecot/ protocols = imap imaps pop3s log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info login = imap login = pop3 verbose_ssl = yes auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes

[Dovecot] openssl config.
by Tom Allison 09 Nov '03

09 Nov '03

I checked and I do have the openssl-devel rpm installed SuSE 8.2 openssl-devel-0.9.6i-12 openssl-0.9.61-19 dovecot 0.99.10 ./configure --with-ssl-openssl At the end of the configuration it says ssl support == 'no' :(... I was able to get pam support by picking up the pam-devel modules as suggested. But I got stuck here. After reading up a bit on imap, it seems reasonable to have both imap and imap-ssl support. imap for localhost connections (like squirrelmail) and imap-ssl for everything else.

[Dovecot] 0.99.10.1 RC
by Timo Sirainen 08 Nov '03

08 Nov '03

Available from http://dovecot.fi/rc/ While still waiting for .11 with index file rewrites to stabilize, here's a release candidate for 0.99.10.1 which is basically 0.99.10 patched with most of the simple bugfixes from CVS. Some bugfixes such as LIST's children-flags were done with larger rewrites so I didn't try to apply them. All the changes are listed in ChangeLog. The important changes are: * mbox: \Draft and \Deleted flags used opposite flag chars in X-Status header. We were incompatible with other mbox accessing software. WARNING: Upgrading from previous version doesn't automatically swap the flags, so be careful not to accidentally expunge messages that had their \Draft flag changed to \Deleted. * Configuration file changes: - Whitespace at end of line is stripped, use quotes if you need it - # comments are supported after key=value lines. if you need '#' character, quote the value - Both " and ' quotes are supported. If you need to use them, '\' can be used for escaping. - mbox: COPY into same mailbox didn't work and could have corrupted the mailbox - Using Dovecot without index files would crash after using a while - Partial BODY[header] or BODY[part] fetches were buggy if client requested more data than was available in the header/part. - Partial BODY[...] fetches were buggy with messages that had CRLFs - Some BODY and BODYSTRUCTURE replies missed data for message/rfc822 MIME parts causing clients to break - SORT (SUBJECT) was buggy - Timezone fixes with Date-header

[Dovecot] [POP3] RFC2449 conformance?
by Matthias Andree 08 Nov '03

08 Nov '03

RFC2449 Section 5 ("Capabilities available in the AUTHORIZATION state MUST be announced in both states.") requires that POP3 extensions offered in Authentication state MUST be offered in Transaction state as well, this affects the "SASL" extension. This is a CVS version that is a couple of days old (the old 0.99.10 wouldn't run on Linux 2.6 because it has tighter resource limiting): +OK dovecot ready. capa +OK CAPA TOP USER UIDL RESP-CODES SASL PLAIN . user SECRET +OK pass VERYSECRET +OK Logged in. capa +OK CAPA TOP USER UIDL RESP-CODES . quit +OK Logging out. -- Matthias Andree

[Dovecot] pop3s fails, imaps works great
by Darren David 08 Nov '03

08 Nov '03

hey all- i'm running dovecot-0.99.10p2 on OpenBSD 3.4-snapshot (installed from ports). i have had 0 problems with imaps -- it's been running like a charm! however, i'm trying to get pop3s set up for some of my users, but i can't seem to connect from ANY client. in /etc/dovecot.conf, i've got: protocols = imaps pop3s and i've also got pop3s_listen set up with the same IP as imaps. i'm using vpopmail for auth. nmap shows that port 995 is open, and netstat does show an established connection to pop3s when i attempt to connect, but i see no activity in the dovecot log, and the client just churns and churns and eventually i have to quit it since i get no response. any ideas what i could have wrong, or how to test? thanks in advance, darren david

[Dovecot] PATCH: make local IP address available to auth modules
by Matthew Reimer 04 Nov '03

04 Nov '03

The attached patch makes the local IP address to which the client connected available to the authentication modules; i.e., the local IP address is available for substitution as %i for the mysql and pgsql modules. We needed this feature to support thousands of our legacy accounts which are authenticated by username/local_part (not the full email address) and IP address (one per domain). Timo, would this be acceptable to commit? One further improvement would be to make the remote IP address available as well, in case one wanted to implement a tcpwrapper-like functionality.

Thanks, all. I'm definitely leaning toward Dovecot. Cyrus is just too big a pain for very little payoff.

[Dovecot] current CVS seems to have index problems.
by Andreas Jaekel 04 Nov '03

04 Nov '03

Hi Timo. I've checked out the current CVS version and tested it. There seems to be a problem when dovecot accesses mailboxes for the first time: I have a mailbox with 4 mails, and no special IMAP headers. (no X-IMAPBase, X-UID etc.) and it's in mbox format. I log in, SELECT the folder and do FETCH 2 BODY[] and receive only a snipplet of the mail from somewhere in the middle of it. After some debugging it seems like dovecot: 1. creates an index, for mbox_index_rewrite(), 2. rewrites the mbox, but then 3. forgets to update the index after the rewrite. and ends up in a state with a pre-rewrite index but a post-rewrite folder. Now, there are many ways to make dovecot rebuild the index after rewriting the folder, but some are ugly and some are not, some need extra code to avoid endless loops. I don't know how you would want this fixed. I attached a patch that worked for me. After that patch, I have more (new?) problems, which may or may not be related. Now, when I SELECT a folder and do a COPY within the folder (*smile*) I get this: A COPY 1 INBOX * BYE Mailbox is in inconsistent state, please relogin. Connection closed by foreign host. ... which is what I'm gonna start looking for right now. :) Regards, Andy

[Dovecot] dies on start-up: Auth process

[Dovecot] Debian bug #201444: More verbose logging
by Jaldhar H. Vyas 03 Nov '03

03 Nov '03

I brought this up a while ago but the submitter is wondering if there has been any progress on this issue. He says: It would be extremely nice to have a little bit more detailed logging, and I believe it doesn't really require that much code. I use now a daemon which logs login (name, ip; as dovecot does), and logout (with name, logout reason if any special) with the numbers of "read new mail number and size" and "mail left on server number and size". Would be nice to have something like that in dovecot. Could something like this be added for the next version? -- Jaldhar H.

[Dovecot] Problems finding information on passwd-file
by David A. Desrosiers 03 Nov '03

03 Nov '03

I've recently converted over to dovecot to uw-imap, and am having a heck of a time trying to find actual docs that describe how to set up virtual users properly without using ldap or posgres.. Basically I need to know what goes in auth_userdb and auth_passdb for a system with *NO* local user accounts in /etc/passwd and /etc/shadow. I will only create mbox files for these users in /var/mail/%u and alternately a home directory where they can store their own mail folders under /home/%u. How can I do this, given the current dovecot codebase? I've googled for a few hours, talked to many people on irc, and checked the mailing lists (of what I could find) related to this, and found nothing whatsoever describing how to achive this. Dovecot apparently supports "virtual users", but I can't find any supporting documentation that describes exactly HOW to set that up. Thanks in advance. d.

We should not conceal aspects of our faith so as to avoid criticism or disapproval, and we should not ask others to do that. We believe it is just and loving to point out publicly the errors of other faiths, provided this is done with sufficient evidence that the sacred writings or representative spokesmen of those faiths do indeed express these errors. We must strive not to misrepresent other faiths, as that is not only disrespectful but also undermining of our own credibility.<P> 2. We should acknowledge our sin and desperate need of salvation by a crucified and risen Savior, and not posture ourselves as worthy of salvation as if we had superior intellect or wisdom or goodness. We are beggars who have, by grace, found the life-giving bread of truth, forgiveness, and joy. As we expose the errors of other religions, we should feel and express sorrow and compassion for those who do not embrace Christ so as to be saved.<P> 3. We should not expect a fair fight in a secular world that is hostile to God and uncomfortable around the truth of Christ. Therefore, our response to abuse, distortion, or slander should not be angry resentment, but patient witness to the truth, in the hope and with the prayer that returning good for evil may open hearts to the truth. We must recognize that persecution is normal and that much of the protection Christians have in America is abnormal in history and in the world. Our witness will be best advanced by kind, steadfast statements and reasonable defenses of the truth.<P> 4. We should renounce all violence as a means of spreading our faith. Christians spread biblical faith by suffering, not by causing suffering. Authentic Christianity cannot be coerced by force or manipulation. We should acknowledge and proclaim that Christ will, at his personal appearing, punish those who have rejected him; his violence at the end of the age is a decisive reason we should not and may not exert violence against anyone because of his beliefs. This is Christ's right, not ours.<P> 5. We believe that God has given to civil government, not individuals or the church, the duty to bear the sword for justice and safety. Civil authorities should not punish beliefs, but some behaviors rooted in beliefssuch as killing, assault, or theftmay be outside the law and therefore punishable by the civil authority. Which behaviors are legally prohibited in a society based on freedom of belief and religion will be determined in a process of persuasion, debate, and election of representative lawmakers, with checks and balances provided by the executive and judicial branches and by constitutional safeguards for the rights of minorities.<P> 6. We should distinguish between a just war of defense against aggression and a religious war against people because of their beliefs. We should acknowledge that this distinction will probably not be recognized by certain religions that define their beliefs to include the right of cultural domination by force. But we should insist on this distinction rather than accept the claim of aggressors that our resistance is a religious attack on their faith. We should argue that the ground of such national defense is the civil right to freedom (of religion and speech and press and assembly), not disapproval of the religion underlying the attack.<P> 7. We should distinguish between the right to express criticism of erroneous beliefs and sinful behaviors, on the one hand, and the false inference some draw from this criticism that proponents of the criticized beliefs can therefore legitimately be mistreated. We also should not accept the claim that being criticized or denounced as mistaken or as sinners is a form of mistreatment. It is not a crime (hate crime or otherwise) to say publicly that someone's belief is wrong and harmful, or to call someone's behavior sinful and destructive. A necessary part of all debate concerning beliefs, behaviors, or proposals is the argument that some are wrong, ill-founded, and have deleterious effects.<P> 8. We believe that every religion, worldview, or philosophy of life may freely endeavor to influence and shape our culture. We renounce the use of force or bribery or deceit in this culture-shaping effort. We affirm preaching the gospel, publishing truth, and modeling love and justice, as well as prayer, persuasion, and participation in the political process. We recognize that all laws "impose" some group's behavioral conviction on all, so it is not a compelling criticism to say that a law that governs behavior is bad because it "imposes someone's morality" on society. It is therefore particularly vital to support principles, laws, and policies that protect the legal freedoms of minorities that do not have the numbers to sway lawmaking processes.<P> These principles are further developed at the website http://www.desiringgod.org/library/topics/culture/tolerance_principles.html  <BR></TD><TD width="200" valign="top"> <link rel="Stylesheet" href="/world/right-bar-basic.css" type="text/css"></link> <style type="text/css"> @import: "/world/right-bar-advanced.css"; </style> <div id="rightbar"> <div id="listenlinks"> <h4><a target="_top" href="/world/listen/">Listen to WORLD</a></h4> <div>Daily radio shorts by Nick Eicher. <a target="_top" href="/world/listen/">Read more...</a><br /> <p><img src="/world/image/speaker.gif" height="11" width="12" /> <a target="_top" href="/world/listen/home.asp?file=000000201.mp3">10/7/02 download MP3</a></p> <p><img src="/world/image/speaker.gif" height="11" width="12" /> <a target="_top" href="/world/listen/home.asp?file=000000199.mp3">10/8/02 download MP3</a></p> <p><img src="/world/image/speaker.gif" height="11" width="12" /> <a target="_top" href="/world/listen/home.asp?file=000000198.mp3">10/9/02 download MP3</a></p> <p><img src="/world/image/speaker.gif" height="11" width="12" /> <a target="_top" href="/world/listen/home.asp?file=000000197.mp3">10/10/02 download MP3</a></p> <p><img src="/world/image/speaker.gif" height="11" width="12" /> <a target="_top" href="/world/listen/home.asp?file=000000196.mp3">10/11/02 download MP3</a></p> </div> </div> <div id="recentlinks"> <h4><a target="_top" href="/world/meta/archives/">From Previous Weeks</a></h4> <div> <p><a target="_top" href="/world/issue/10-05-02/"><img src="/world/issue/10-05-02/image/cover_thumb.jpg" width="72" height="97" /><br /> October 5, 2002</a></p> <p><a target="_top" href="/world/issue/09-28-02/"><img src="/world/issue/09-28-02/image/cover_thumb.jpg" width="72" height="97" /><br /> September 28, 2002</a></p> <p><a target="_top" href="/world/issue/09-21-02/"><img src="/world/issue/09-21-02/image/cover_thumb.jpg" width="72" height="97" /><br /> September 21, 2002</a></p> </div> <br /> <a href="http://worldmag.com/world/classifieds/"><img src="/world/image/side_ads/Searching_Ad_100x180.gif" width="180" height="100"></a> </div> </div> </TD></TR> </TABLE> <BR> <TABLE BORDER="0" WIDTH=520><TR><TD WIDTH=110 ALIGN=right VALIGN=top><FONT COLOR=ffffff><B>Search for more<BR>articles about:</B></FONT><BR></TD><TD WIDTH=40><BR></TD><TD WIDTH=370 VALIGN=top ALIGN=left BGCOLOR="#CCCC99"> <TABLE WIDTH="370" BORDER="0" CELLPADDING="8" CELLSPACING="0"><TR><TR><TD WIDTH="370" ALIGN="LEFT" VALIGN="top"><form name="searchForm" action="/world/meta/search/search.asp" onsubmit=""> <input type="hidden" name="performSearch" value="y"> <INPUT TYPE="text" NAME="target" SIZE="30" MAXLENGTH="100"><br> <input type=checkbox name="stype" value="phrase" checked> exact phrase </TD><TD ALIGN="LEFT" VALIGN="TOP"> <INPUT TYPE=SUBMIT VALUE="search"></FORM> </TD></TR> </TABLE> </TD></TR></TABLE> <TABLE BORDER="0" CELLPADDING="0" CELLSPACING="0" WIDTH="500"><TR><TD WIDTH="156"><BR></TD><TD ALIGN=LEFT WIDTH="253"><FONT SIZE="1"><A HREF="/world/meta/copyright.asp" TARGET="_top">© 1996 - 2002 WORLD</A> Magazine. <A HREF="/world/meta/contact/" TARGET="_top">mailbag(a)worldmag.com</A></FONT></TD><TD COLSPAN="1" ALIGN=RIGHT WIDTH="91"><A HREF="#top"><IMG SRC="/world/image/nav/top_bottom.gif" WIDTH="22" HEIGHT="15" HSPACE="10" VSPACE="10" BORDER="0"></A><A HREF="home.asp" TARGET="_top"><IMG SRC="/world/image/nav/contents_bottom.gif" WIDTH="49" HEIGHT="15" BORDER="0" VSPACE="10"></A></TD></TR></TABLE>  <script type="text/javascript"> if(parent.frames.length>0&&!isContents) top.location.replace(document.location) </script> </BODY> </HTML>  --------------010405000308030207040500--

I had trouble with an instantssl cert, and found that what I needed to do was to also include all the certs up the chain, in a certain order, to keep the client from complaining about an invalid certificate. The first certificate in the pem file should be the the server certificate, followed by its chain starting from the root certificate down. Matt

[Dovecot] Copy from INBOX to INBOX corrupts file
by Andreas Jaekel 29 Oct '03

29 Oct '03

Aloha, again, Timo. Concerning the problem of copying within one folder... I'm still not sure it's not a problem I created myself, but I think it's caused by the use of the buffered IO routines in ostream-file.c ... you use io_add() to schedule write operations for later while simultanously reading new chunks from the very same file. This seems to confuse dovecot and make it write the copy to the strangest locations. I think when working within one folder I should use either blocking IO or a lot of calls to o_stream_flush()... what do you think? Greetings, Andy

Hi, Just a quicky, I can't see anything about how Dovecot handles certificate chains. 1, Does it handle them? 2, How, if if does? (Just got a cert from www.instantssl.com and I need there intermediate cert do validate it.., Works fine with Apache and Exim ) Cheers, Steve Gare - Xantara.Net -- 0845 123 5707

[Dovecot] Shared Folders
by D Canfield 21 Oct '03

21 Oct '03

I was just wondering if any thought has been given to shared folders and how they might be implemented yet? True shared folders are compelling enough to our organization that I've been looking into moving to Cyrus from Courier, but transparent folder migration looks to be nearly impossible for more than a handful of accounts... so that leaves me back at hoping courier or dovecot can eventually do what we want. We have a lot of organizations on campus that have a generic mail address such as "maintenance" of "physics." We don't like the idea of shared accounts (invariably either the mailbox gets forgotten about when a secretary changes, the password gets lost, or everyone on campus ends up with the password), so our policies require such generic accounts to be forwarded to a folder in a "real person's" account. This works well for us, but the users are clamoring for the ability to have more than one person access those folders. The problem with Courier's shared folders is that one person owns the folder and while others can see that mailbox, only the owner has write access. This kills most of the utility of shared folders, except for use as announcement areas. As I understand it, the reason Courier does it this way is that it uses the underlying unix permissions to control access to the mailbox. I'm thinking that even if dovecot uses the same concept for shared folders, it should be possible to allow multiple users to write to the folders if filesystem ACL support is used. At least ext3 and XFS both support ACL's, so there is a reasonable amount of support for them, and they would allow dovecot to give multiple users write access to the folders without having to manage it's own security system. The only issue would be that the delivery agent would have to make sure that that ACLs for a folder are kept consistent... I'm not even sure dovecot has to be ACL-aware. Anyway, if there is a completely different plan in the works, that's great too, but I wanted to at least voice an opinion and offer a suggestion of how to make it work. Thanks DC

[Dovecot] A view quirks
by Andreas Jaekel 21 Oct '03

21 Oct '03

Aloha Timo. I found a few odd things while playing with dovecot. At least one of them bugs me, but it might be a result of my own patches - I haven't testet it with mbox or maildir, yet. The details :) 1. * OK dovecot ready. A = (<return> Connection closed by foreign host. 2. * OK dovecot ready. A001 LOGIN xxxxxx xxxxxx A001 OK Logged in. A002 COPY 1 INBOX Connection closed by foreign host. (segfault) 3. [...] A003 SEARCH SUBJECT "test" * SEARCH 1 A003 OK Search completed. A004 SEARCH SUBJECT {6} + OK "test" * SEARCH A004 OK Search completed. I think these two searches should give identical results. 4. (my current nemesis) A002 CREATE bla A003 SELECT INBOX A004 COPY 1 bla A005 SELECT bla A006 COPY 1 bla * NO Internal error [2003-10-16 16:07:21] A006 OK Copy completed. If I copy from the current folder to the current folder I get a scrambled mailbox and an error. This might be selfmade, though. I'm currently trying to find this bug, but the various layers of [_oi]streams and callback and function pointer structs do not help :) I think the stream routines hide the mstream(istream(realstream(iostream))) and the ostream(_ostream(iostream)) behind the same file descriptor and the data gets written to the wrong position. BTW: what exactly is "max_pos"? Greetings and thanks! Andy

[Dovecot] problem getting mail from mbox
by Gavin Estey 16 Oct '03

16 Oct '03

I'm trying to set up dovecot and I'm running into a few problems. I just want to use IMAP for one user, everyone else gets POP3 from the existing (working server). $MAIL is set to /var/spool/mail/gavin_imap In my /var/spool/mail directory I now have a problem: -rw------- 1 gavin_im mail 1392 Oct 14 22:28 gavin_imap -rw------- 1 gavin_im popusers 0 Oct 14 21:54 gavin_imap When I try to get my mail, I guess it's checking the wrong file as I can't download anything. I also can't delete the file (which I find confusing as I am root): [root@chicken mail]# rm gavin_imap rm: cannot remove `gavin_imap': No such file or directory I actually have the same problem with the dovecot log file. I have this in my config: info_log_path = /tmp/dovecot -rw------- 1 root root 4436 Oct 14 22:40 dovecot [root@chicken tmp]# cat dovecot cat: dovecot: No such file or directory I don't get any obvious errors if I telnet in: [root@chicken tmp]# telnet localhost 143 Trying 127.0.0.1...

[Dovecot] exchange, dovecot, mutt, evolution
by Krammer Clemens 16 Oct '03

16 Oct '03

Dear all, When I "migrate" my outlook folders to imapd (dovecot) it works well from a Windoze perspective, but if I open a migrated folder via imap (mutt, evolution) a cannot see the Senders. If i open the folder locally via mutt, the Senders are displayed correctly. By examining one folder with vi I recognised that there are no valid From headers but Return-Paths. Is there a common way to see the senders when connecting with imap? Best Regards, Clemens

[Dovecot] Ordering mailboxes
by Ian Marlier 16 Oct '03

16 Oct '03

I have a really weird problem. To whit: I compiled dovecot 0.99.10 on two different systems: a linux-ppc box running Debian, and a Mac OS X Server v. 10.2.8. It compiled fine on both. The same Maildir's are being served up on both -- the OS X server exports home directories to the clients via NFS. BUT the OS X box orders mailboxes this way: INBOX Deleted Items Sent Items . . . And the Debian box orders mailboxes this way: INBOX INBOX/Deleted Items INBOX/Sent Items . . . The compilation options were the same in both cases.

[Dovecot] Ignore purge and delete command
by vikrant＠linmark.com 16 Oct '03

16 Oct '03

Hi, Does anyone know how to ignore the purge or delete command from the imap clients. Actually I created a mail archive and using dovecot and so far I am happy with the performance. But the problem I am facing right now is I do not want the users to delete the mail by themselves and want to disable the purge or delete command. Thanks Vikrant

[Dovecot] dovecot crashes on start
by Timothy 16 Oct '03

16 Oct '03

Hello, I wasn't able to find anything about this on the site that could give me a definite answer, but when I start dovecot it dies immediately. The following is left in the logs. dovecot: Oct 06 20:59:30 Info: Dovecot starting up dovecot: Oct 06 20:59:32 Error: Auth process died too early - shutting down pop3-login: Oct 06 20:59:32 Fatal: fd_send(-1) failed: Broken pipe I thought this might have something to do with chrooting so I tried to disable all of that in the configuration. After that did not work I rebuilt dovecot with minimal configure options (compared to what I used originally) and used a stock configuration changing only the certificate locations so that dovecot would not complain about the certificates missing, still no luck and the same error. I've tried using strace on dovecot but it seems like it hardly ever hangs/dies at the same point. I'm trying to run this on a slackware 9.0 linux based machine. Any suggestions?

[Dovecot] gzipped files in Mail directory
by Olivier Tharan 09 Oct '03

09 Oct '03

Hi, I have been testing dovecot on my own machine before a bigger deployment. Basically I have all my mbox mailboxes in ~/Mail, delivered by procmail. Some mbox's are gzipped because they are archives which I can grep into, but do not want to look at often. When I first launched an IMAP client, dovecot created the indexes (I think) and gave several errors when finding a gzipped file, such as: ,---- | Oct 1 19:53:21 mafate imap(olive): File isn't in mbox format: /home/olive/Mail//Archives/daily.d/mafate.2003.gz `---- After 19 gzipped mbox's, I had the following crash: ,---- | Oct 1 19:53:21 mafate dovecot: child 4923 (imap) killed with signal 10 `---- Does dovecot not like gzipped mbox's? For the moment, all gzipped files are in ~/Mail/.Archives and I can live with it. -- olive

[Dovecot] Line length limitation in dovecot leads to out-of-control process?
by Amelia A. Lewis 09 Oct '03

09 Oct '03

Heylas! I've been copying mailboxes from one dovecot server (on an alpha running debian testing, 0.99.10-9) to another (on an i686 running debian unstable, 0.99.10-9). I encountered a weird problem, which I seem to have resolved by moving a message with a To: line from hell out of the mailbox. Both machines are running maildir. They're not exactly identical, but they're fairly similar, apart from differences in distribution and architecture; they're running the same version of dovecot, supposedly. Specifically, when I copied this folder over to the new location, dovecot went into CPU-feeding frenzy (up to 99.7% of CPU), and stayed there. If I killed the client and tried to look at the same mailbox using a different client (mutt instead of sylpheed), without killing the imap processor on the server, the indexes would be locked, mutt would fall back to reading headers instead, and then would send its imap process into CPU-feeding frenzy when it got to one particular message. After some experimentation, I found the message. Once I moved it out of cur, I could access the mailbox without problems. The odd thing is that I can look at the message on the original machine, but on the machine it was copied to, its mere existence makes the mailbox inaccessible. After a little more exploration (grep ^To name-of-message | wc, on both machines) I seem to have found the issue: the original message has a To: line that is 16504 characters long. In the copy, it's 8192 characters long, and ends in the middle of a <email@address> (line in copy ends: user name <emai, chopped right there). I suspect that it is the *latter* that's causing dovecot to die a messy death. Or, actually, to turn into a very *rude* process that *doesn't* die. It's a really stupid trick to stuff that much into a header line (it's from helixcode in 2000, btw, notifying people that the promised CD is late), and perfectly reasonable to truncate (even to truncate to 1000 characters, per 282[12]). However, I kinda thing dovecot shouldn't choke on the results of truncation, which is what I think is the problem. Amy! -- Amelia A.

Oops, I apologize for my short, breif message that didn't even include what I said it should inlcude =). Here's the deal: OpenDarwin 6.6 (closest relative being Mac OS X 10.2.6) won't build from CVS. Specifically libtoolize doesn't seem to exist (does it even come with libtool?) and the other parts of the "autogen.sh" fail miserably. This time (really) attached is a gzip of the log of autogen.sh: "./autogen.sh >& autogen.log". Thanks for any help! - Jesse

[Dovecot] those assertions
by dovecot＠spam.turbolink.net 06 Oct '03

06 Oct '03

Timo, Just FYI while you're working on the mbox code, I discovered a bug that occasionally causes dovecot to insert a single blank line at the beginning of the mbox, I'm not sure when/how/why. A single blank line seems to really confuse dovecot, and causes the server to crash when somebody connects to an afflicted mbox. ("Error indexing mbox" in the log, and disconects the user right away). I fixed it with lots of ugly code at our site (basically just remember that we skipped an intial blank line when doing other operations, instead of skipping it then forgetting later). I suspect there's a more elegant way to do it. - Mike

[Dovecot] SSL Client Certificate Support
by Bert Koelewijn 06 Oct '03

06 Oct '03

Dear Timo, most modern enterprises make use of a Public Key Infrastructure. It would be nice to have dovecot check a client certificate instead of a password. This makes life much easier and more secure. Mail clients like Mozilla and MS Outlook do support this. What do you think of the following feature request: - Client authenticates with a certificate via SSL. (Like stunnel can) - Dovecot looks the username up in a table with (public key, username) - The mailclient gives a name and password, but dovecot ignores them - Dovecot gives the client access by the username found in the table This way existing mail clients can use this system and you can save your username with an empty password. Best Regards, Bert Koelewijn

Hi, I did a bit of digging into the assertions from mbox-rewrite.c (hdr_parsed_size.physical_size == hdr_size).

I can't manage to get hold of an mbox that causes this though. Another infrequent assertion that's popped up: file message-address.c: line 262 (message_address_write): assertion failed: (addr->domain != NULL) And one that's only ever been spotted once in the last few weeks: file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) I'm waiting for them to happen again to provide some more info... Regards, Bernard. -- Bernard Blackham bernard at blackham dot com dot au

[Dovecot] another Dovecot problem
by Tim Miller 05 Oct '03

05 Oct '03

Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't have madvise, yet it's prototyped in /usr/include/sys/mman.h. This causes the compilation to fail when dovecot tries to redefine this function. -- I attempted to solve this problem by renaming the function dovecot prototypes to dc_madvise and then changed all the calls in the code (and the implementation) from madvise to dc_madvise. This allows the code to compile correctly. -- However, once the server is installed, it does not appear to work correctly. I can login, but when I try to list my folders or select any folder (one that exists or one that doesn't exist) the connection times out and the following entry is written to the log file: dovecot: Oct 03 05:38:56 Error: login: received another "not listening" notification (if you can't login at all, see src/lib/fdpass.c) I tracked this message down in the source, but didn't see any obvious way to trace back the problem. Does anyone have experience building on this older configuration (the glibc is a Red Hat version, if it makes any difference)? Any ideas on what might be causing this issue? Best, Tim Miller

Well, on our systems the mailbox is in /var/mail in maildir format, and in ~/Mail users have split up their folders in subdirs, in mixed maildir and mbox formats. So if dovecot could support both dotless directory-structured mailbox locations and maildir/mbox mix-n-match in the same tree, that would be excellent for us. Mbox is a better format for archiving. Now if Dovecot could also access (read-only ofcourse) compressed mbox archives ... Food for thought. Just put it on the wishlist ;) Mike.

[Dovecot] Patches
by Jaldhar H. Vyas 05 Oct '03

05 Oct '03

As the freeze for Debian sarge slowly approaches I want to make sure the Dovecot packages are in as good condition as possible. I see there have been a number of patches since 0.99.10. I have added the following patches: * segfault when user home directory is empty * Proper PAM service name * Make suid work on 2.6 kernels Any other patches thatI ought to add. Or better yet, will there be a 0.99.11 soon? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[Dovecot] Why does dovecot confuse mutt?
by Amelia A Lewis 04 Oct '03

04 Oct '03

Heylas, I just switched my primary mail server from courier imap to dovecot (I've been waiting to do this; dovecot showed up in debian testing for alpha, at last). So, using the same set of maildirs, there are slightly different behaviors. First, of course, dovecot displays the hierarchy as I thought it ought to be, such that INBOX is a sibling of all other top-level boxes, not the parent of everything. This is A Good Thing[tm]. That works as expected. However, as far as mutt is concerned, *every* mailbox has child folders. My muttrc contains the line: set folder=imap://localhost/. (and the home folder is set to imap://localhost/INBOX; the idea is to do all mail munging through the server, never directly touching the maildirs with an MUA). Oh, and I'm using maildir (~/Maildir). In mutt, from the currently-selected mailbox, one can use 'c' to change boxes, and ? displays a navigable folder hierarchy. If a folder contains only mail (no child folders), it shows up as "FolderName", if it has child folders (whether or not it has mail), it shows up as "FolderName.". You can display the mail in a folder that has child folders, but it requires a different keystroke than the default (enter selects a folder, which means showing child folders if there are any, showing mail if there aren't; to display mail in a folder that has child folders, space). This is tripping me up a little, because of course the commands are mostly bred into my fingertips, and it's a difficult adjustment. I hit return, and I see a folder that contains the "child" folder "../". Is this a glitch in mutt's handling of information that I ought to report to mutt maintainers? Is it a glitch in dovecot's presentation of information that I ought to report to ... err, well. *laugh* My other primary mail client seems to cope beautifully with the information that's supplied (sylpheed, if it matters). But then, sylpheed also coped perfectly when courier was supplying information. I gather that courier and dovecot are reporting something slightly different, somehow, but I don't really know what, and I don't know which should be considered "correct". Amy!

[Dovecot] mailbox sorting issue

Thanks for the "junk at end" help. Now I'm having one more perplexing issue: When I sort a Dovecot mbox in Pine, the most recent messages tend to linger near the bottom of the message list, regardless of how they're sorted.

I'm not 100% sure that this is a Dovecot issue, but I suspect it is, since this doesn't happen if I open the same mailbox locally or with UW-IMAP. I know that Pine makes use of IMAP server-based sorting if it is available. I tried deleting .imap-index* files, just in case, but that didn't help. thanks, Paul

Here's another patch. This one isn't much different from the last patch, except it tries a little harder to make sure that the required fields are returned by the query (like the pgsql module does). One question about how t_strdup works. How and who should memory returned by t_strdup be freed? My patch has a function my_get_str() which returns the value of t_strdup, and then I do this: user.uid = atoi(my_get_str(res, row, "uid")); /* XXX leak */ user.gid = atoi(my_get_str(res, row, "gid")); /* XXX leak */ Will this result in a memory leak?

I'm not sure what you mean by asynchronous database lookups. Do you mean you'd like to be able to fire off a db lookup and then come back later to get the results? Like blocking vs non-blocking? I've pasted what may be relevant mysql documentation below in case it might help answer the question. N db handles could be allocated, giving us N simultaneous lookups. Matt --- From http://www.mysql.com/doc/en/C_API_function_overview.html: There are two ways for a client to process result sets. One way is to retrieve the entire result set all at once by calling mysql_store_result(). This function acquires from the server all the rows returned by the query and stores them in the client. The second way is for the client to initiate a row-by-row result set retrieval by calling mysql_use_result(). This function initialises the retrieval, but does not actually get any rows from the server. In both cases, you access rows by calling mysql_fetch_row(). With mysql_store_result(), mysql_fetch_row() accesses rows that have already been fetched from the server. With mysql_use_result(), mysql_fetch_row() actually retrieves the row from the server. Information about the size of the data in each row is available by calling mysql_fetch_lengths(). After you are done with a result set, call mysql_free_result() to free the memory used for it. The two retrieval mechanisms are complementary. Client programs should choose the approach that is most appropriate for their requirements. In practice, clients tend to use mysql_store_result() more commonly. An advantage of mysql_store_result() is that because the rows have all been fetched to the client, you not only can access rows sequentially, you can move back and forth in the result set using mysql_data_seek() or mysql_row_seek() to change the current row position within the result set. You can also find out how many rows there are by calling mysql_num_rows(). On the other hand, the memory requirements for mysql_store_result() may be very high for large result sets and you are more likely to encounter out-of-memory conditions. An advantage of mysql_use_result() is that the client requires less memory for the result set because it maintains only one row at a time (and because there is less allocation overhead, mysql_use_result() can be faster). Disadvantages are that you must process each row quickly to avoid tying up the server, you don't have random access to rows within the result set (you can only access rows sequentially), and you don't know how many rows are in the result set until you have retrieved them all. Furthermore, you must retrieve all the rows even if you determine in mid-retrieval that you've found the information you were looking for. --- end

[Dovecot] can't read attachments using javamail with dovecot
by Jonas Bosson 03 Oct '03

03 Oct '03

Dear folks, this might be a java-bug, but it seems to occur only when connecting to dovecot-IMAP. UW and Cyrus-ditto works, while when I try to read attachments (base64), I get slapped in the face with this: java.lang.NullPointerException at com.sun.mail.iap.Response.parse(Response.java:99) at com.sun.mail.iap.Response.<init>(Response.java:68) at com.sun.mail.imap.protocol.IMAPResponse.<init>(IMAPResponse.java:31) at com.sun.mail.imap.protocol.IMAPResponse.readResponse(IMAPResponse.java:105) at com.sun.mail.imap.protocol.IMAPProtocol.readResponse(IMAPProtocol.java:153) at com.sun.mail.iap.Protocol.command(Protocol.java:215) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:882) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:874) at com.sun.mail.imap.protocol.IMAPProtocol.fetchBody(IMAPProtocol.java:677) at com.sun.mail.imap.IMAPInputStream.fill(IMAPInputStream.java:74) at com.sun.mail.imap.IMAPInputStream.read(IMAPInputStream.java:105) at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:143) at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:54) at se.illuminet.httpd.mail.MailXMLService.serviceXml(MailXMLService.java:361) This occurs in booth javamail 1.2 and 1.3(.1) using dovecot. Of course this unfriendly/unhandled response is a problem with javamail while biting the dust. Further analysis points to that the reading works OK up until 2^16 bytes, so it fails either in reading the tail of the attachment or resuming after the first buffered data is consumed. I tried the BODYSTRCUTURE-patch (booth #1 and then #2), but it didn't help. Now I am fresh out of ideas. The java-bug has a three week delay to surface on "bug-parade". But I still have to explain why it works in UW/Cyrus and not with dovecot. Next step would be to add trace-lines in dovecot. Any ideas? /Jonas

[Dovecot] pop3s in Outlook

Hi, I'm using Dovecot for pop3-ssl. Unofortunatelly, most of my users are using MS Outlook. I want them to be able to remove standard mesage: "The certificat is not signed by...", but I don't know how :-( In the dialog isn't a button "Trust this certificate forever"... Is there anybody, who know, how to solve this? Many thanks.

[Dovecot] Handling of X-Status flags
by Bernard Blackham 29 Sep '03

29 Sep '03

Hi all, I've done a bit of searching and haven't seen anybody else coming across this problem yet: I noticed that Dovecot uses the opposite flags for marking messages as deleted and draft to most other MUAs I've seen or used: With PINE, mutt and uw-imapd at least, messages are marked with X-Status 'D' for Deleted, and 'T' for drafT. Dovecot reverses this behaviour, using 'D' for Draft, and 'T' for Trashed. Was there any reason behind this? Or have I gone loopy? At our site, we have users reading mail with a mix of PINE locally, and through dovecot via WebMail and there seems to arise a bit of confusion between the two flags. Attached is a patch that reverses this behaviour (prepared against 0.99.10 but applies with a little fuzz to cvs). I'd like to hear people's comments on the issue... is it just me? :) Thanks, Bernard. -- Bernard Blackham bernard at blackham dot com dot au

[Dovecot] Odd problem with dovecot segfaulting
by Tim Miller 29 Sep '03

29 Sep '03

Hi All, I installed dovecot on one of my servers the other day, and I want to use it in a vhosting environment. To this end, I have set it up to use password file authentication with a passwd file specified by me. This file will contain both system users and virtual accounts. To test it, I set up two accounts in the dovecot passwd file. One is a system user, I give his home dir in the correct field, along with the MD5 hash of his password in its field, and everything seems to work OK (he can login, read mail out of /var/spool/mail/user etc.). The seconmd account is a vhosted account, and I set the uid and gid to that under which the vhosting account exists. I did not set a home dir, but I set a mail dir in /var/spool/vmail/imap/vhost/user, and made this dir group writeable by dovecot. The user can login, but immediately upon authentication, dovecot segfaults (the log reports an "Internal login failure" and the authentication process is killed with signal 11, i.e. a segfault). Has anyone encountered this before? Is this even the right way to set up vhosting (I don't want to go with LDAP or SQL authentication right at the moment, but I may move to that later on)? Are there any things I should look for (this is probably due to something I've done wrong) or make dovecot be a bit more verbose in reporting errors to its log? Thanks in advance for any help. From what I've seen so far, dovecot looks like an excellent product. Best, Tim Miller

UW and Cyrus-ditto works, while when I try to read attachments (base64), I get slapped in the face with this: java.lang.NullPointerException at com.sun.mail.iap.Response.parse(Response.java:99) at com.sun.mail.iap.Response.<init>(Response.java:68) at com.sun.mail.imap.protocol.IMAPResponse.<init>(IMAPResponse.java:31) at com.sun.mail.imap.protocol.IMAPResponse.readResponse(IMAPResponse.java:105) at com.sun.mail.imap.protocol.IMAPProtocol.readResponse(IMAPProtocol.java:153) at com.sun.mail.iap.Protocol.command(Protocol.java:215) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:882) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:874) at com.sun.mail.imap.protocol.IMAPProtocol.fetchBody(IMAPProtocol.java:677) at com.sun.mail.imap.IMAPInputStream.fill(IMAPInputStream.java:74) at com.sun.mail.imap.IMAPInputStream.read(IMAPInputStream.java:105) at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:143) at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:54) at se.illuminet.httpd.mail.MailXMLService.serviceXml(MailXMLService.java:361) This occurs in booth javamail 1.2 and 1.3(.1) using dovecot. Of course this unfriendly/unhandled response is a problem with javamail while it bites the dust. Further analysis points to that the reading works OK up until 2^16 bytes, so it fails either in reading the tail of the attachment or resuming after the first buffered data is consumed. I tried the BODYSTRCUTURE-patch (booth #1 and then #2), but it didn't help. Now I am fresh out of ideas. The java-bug has a three week delay to surface on "bug-parade". But I still have to explain why it works in UW/Cyrus and not with dovecot. Next step would be to add trace-lines in dovecot. Any ideas? /Jonas

[Dovecot] Multiple instances of .customflags staying open
by Ron 25 Sep '03

25 Sep '03

# cat /proc/version Linux version 2.4.20-18.9 (bhcompile(a)daffy.perf.redhat.com) (gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu May 29 07:09:43 EDT 2003 # dovecot --version 0.99.10 I've just recently noticed a serious problem with my system. After about an hour or so I get errors in /var/log/maillog such as this; Sep 21 06:40:16 the-system imap(ray): opendir() failed with file \ \/home/ray/Maildir//new: Too many open files I investigated with 'lsof' and found that many copies of '.customflags' were open for each and every folder. ie; Each folder's '.customflags' file was open 15 times! I suspect that postfix is not able to store newly collected email while this is occuring, therefore I am likely losing messages. I've tried with multiple mail clients (Sylpheed & Evolution) and multiple users, always with the same result. Further investigation indicates that each time the client scans for new mail another instance of each and every '.customflags' is opened. As I have the client set for checking at five minute intervals then it was probably 75 minutes until the client barfed. Less, if I manualy scan for new mail a few times. If I shutdown the client and restart it then everything is fine for about an hour. Running 'lsof /home/ray/Maildir/.customflags' on the server I can see the list of files increasing each time the client checks for new mail. Any help would be appreciated!

[Dovecot] dovecot IMAP misserving problem?
by Warren Togami 23 Sep '03

23 Sep '03

http://togami.com/~warren/archive/2003/evolution-1.4.4-crash.mbox I suspect that dovecot-0.99.10 is misserving this message in some way that is confusing some IMAP clients. This behavior causes evolution-1.4.4 to segfault, and squirrelmail-1.4.1 to be unable to read the message. The same message served by uw-imapd works works fine in both evolution and squirrelmail. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104288 Red Hat Bugzilla dovecot report https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104289 Red Hat Bugzilla evolution segfault report http://bugzilla.ximian.com/show_bug.cgi?id=48418 Ximian evolution segfault report

[Dovecot] feature request: maildirquota
by Eero Volotinen 21 Sep '03

21 Sep '03

Hope maildirquota++ is soon supported, without it, dovecot is useless in my use (mail hosting with maildirquotas). Also QUOTA cabability in dovecot is needed to get to use my webmail plugins that use a001 CAPABILITY to get quota support. Courier imapd supports this. --snippet from quota usage plugin to squirrelmail-- function sqimap_get_quota ($imap_stream, $mailbox) { if (check_quota_capability($imap_stream, "QUOTA")) { fputs ($imap_stream, "a001 GETQUOTAROOT \"$mailbox\"\r\n"); $read_ary = sqimap_read_data ($imap_stream, 'a001', true, $result, $message); for ($i = 0; $i < count($read_ary); $i++) { if (ereg("STORAGE", $read_ary[$i])) { $tempusage = ereg_replace("^.*[(]STORAGE +(.*)[)].*$", "\\1", $read_ary[$i]); $usagearray = explode(" ", $tempusage); return $usagearray[0].":".$usagearray[1]; } } } return "NOQUOTA"; } function check_quota_capability($imap_stream, $capability) { global $imap_general_debug; fputs ($imap_stream, "a001 CAPABILITY\r\n"); $read_ary = sqimap_read_data($imap_stream, 'a001', true, $a, $b); for($i = 0; $i < count($read_ary); $i++) { if (ereg("QUOTA", $read_ary[$i])) return TRUE; } return false; } -- end snippet-- -- Eero

[Dovecot] convert wu-imap Maildir format to dovecot
by Alin Osan 21 Sep '03

21 Sep '03

Hello, I intend to migrate a mail server with Maildir from wu-imap to dovecot imap. Using horde/IMP, users can not access their imap forders, as wu-imap created Mail directory that holds all created folders. Dovecot could not detect the mail directory so I had to put default_mail_env = ~/Maildir in dovecot.conf. Before I begin to read the source-code of dovecot or try to migrate the the mailboxes using a shell script, is there any way I can make dovecot read the wu-imap folders format? Please suggest any solution that you find viable. Thank you. -- -- We are what we repeatedly do. Excellence, then, is not an act, but a habit. -- Alin Osan

[Dovecot] namespaces
by Brian Marcotte 21 Sep '03

21 Sep '03

I'm trying to use the namespaces feature to set up dovecot to look just like our existing Courier IMAP server, and our previous Cyrus server. That is, all folders are subfolders of INBOX, and the hierachy separator is ".". I put this in the configuration file: namespace private { separator = . prefix = INBOX. location = maildir:~/.maildir } This makes subfolders work correctly, but it can't find the INBOX: x1 select INBOX x1 NO Unknown namespace. Also, I don't really want to specify the location here. I want to use the userdb settings (I'm using password-file). Is there a way to make it use my setting in the userdb/password-file? Also, I'm not sure if it actually matters, but when selecting a folder, the number of RECENT messages is always the same as the number of messages which EXISTS: x2 select INBOX.Tech * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 70 EXISTS * 70 RECENT * OK [UNSEEN 69] First unseen. * OK [UIDVALIDITY 1057356619] UIDs valid * OK [UIDNEXT 181] Predicted next UID x2 OK [READ-WRITE] Select completed. I'm afraid some clients may use this information for something, and display incorrect information to the user. Thanks! -- - Brian

[Dovecot] Feature question/request
by Dan Sully 20 Sep '03

20 Sep '03

So I have a bunch of users who are roaming - IE no static IP address from all over the internet. Some of them are able to use SMTP-AUTH which is great, but for those that can't, a pop before smtp solution is in place using relay-ctrl-age & cdb files via qmail. Would it be desirable to have this feature in dovecot? I'd really like to ditch qmail-pop3d, etc. vpopmail has a open_smtp_relay() when using vchkpw directly. -D -- <iNoah> I won't be satisfied until I have a rectally-insertable laptop

[Dovecot] Multiple auth checkers
by Dan Sully 18 Sep '03

18 Sep '03

I noticed this is in the TODO: - support for multiple auth checkers. passdb+userdb should be tied together. auth process configurations really should be used for this.. and is functionality that I really would like, as I have local users (passwd+shadow) and vpopmail users. In -test7's dovecot-example.conf, there is a different format for "blocking" multiple auth types, and I created a conf as such: auth default { mechanisms = plain userdb = passwd passdb = shadow user = root count = 2 } auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail count = 2 } Password authentication still works fine, but I can't find a way to get it to fallback to using the vpopmail auth. Is this simply not working yet? Timo - what part of the code needs this update? Thanks. -D -- Change? We fear change.

Hi, Thanx a lot for your reply. But my log file(its /var/log/dovecot) doesnt have any information other than the following line for example, imap-login: Sep 16 10:31:50 Info: Login: usr1 [127.0.0.1] After this when I give select command or anything like that, its not logged(I dont know also, how to enable maximum debug information, I checked the docs and all) Again, let me tell you that I suspect there is something wrong with the mail environment setting. its as follows default_mail_env = maildir:/var/spool/mail/%u/Maildir and when i give some nonexisting location ( eg; /var/blah/blah) also, I get the SAME ERROR. Here is a sample telnet session Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1).

[Dovecot] Locking foolishness
by Ian Marlier 16 Sep '03

16 Sep '03

I'm working on getting Dovecot set up on my school's mailserver, as an IMAP and POP server. Everything is going well, move over to maildir went well, and all that... The catch: When I coverted from mbox to maildir (as part of this whole process), I put the Maildir folders under user home dirs -- and the home dirs are mounted via NFS from a server. This is for reasons of space as well as simply seeming to make sense. Now I get errors in my mail.log which read: imap-login: Sep 16 00:16:24 dovecot:Info: Login: marlier [209.6.159.188] imap(marlier): Sep 16 00:16:28 dovecot:Error: file_wait_lock() failed with index file /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/.INBOX/.im ap.index: Invalid argument It looks to me like it's a file locking problem...any thoughts on how to get around it? I've already tried the dotlock mechanism alone...without success... More information available upon request... - Ian

[Dovecot] Locking foolishness - Better info
by Ian Marlier 16 Sep '03

16 Sep '03

I realized that my last message about locking gave bad information -- or rather, very little information. Here's my setup: - Home directories and user login information are located on an Xserve running Mac OS X 10.2.6. Home directories are split between 2 different directories -- /Users and /Students. Home dirs are exported via NFS to the mail server. User login info is shared via LDAP to the mail server and to Windows machines in classrooms. - The mail server is an old beige G3 running Debian Woody (linux 2.4.20) kernel. It's completely up-to-date. Homedirs are mounted at /Network/Servers/network.uphamscornercs.net/Users and /Network/Servers/network.uphamscornercs.net/Students, in keeping with the OS X Server userdir name scheme. The only user with a shell on the server is root, other than that all user information is pulled from LDAP using PAM. Postfix is setup to deliver mail to maildir:~/Maildir, and dovecot is set to read mail from the same directory. This is working without any problem. - Clients Entourage works fine to access mailboxes -- it reads mail without a problem. However, it pops up an error message intermittently that reads "Mail could not be read: Internal Error [<datestamp>]". This message doesn't seem to interfere with reading mail, it's just an annoyance. Squirrelmail doesn't work to access mailboxes. It logs in fine, but gives the following error message in all windows that require mailbox access: "ERROR : Could not complete request. Query: <imap query string> Reason Given: Internal error [<datestamp>]" In both cases (Entourage and Squirrelmail), the Internal Error is accompanied by the following error message in the /var/log/mail.log file: "imap(marlier): Sep 16 08:40:45 dovecot:Error: /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/.subscript ions failed with subscription file file_wait_lock(): Invalid argument" So, it looks to me like something isn't working with locking. I'm not sure whether the problem is with the NFS mount, or with dovecot, or with permissions, or something else, but I'd like to get it fixed. I love the server, and if I can get this licked I think I've got a long-term setup. Relevant sections of /usr/local/etc/dovecot.conf: -------- # Use mmap() instead of read() to read mail files. read() seems to be a bit # faster with my Linux/x86 and it's better with NFS, so that's the default. mail_read_mmaped = no # Copy mail to another folders using hard links. This is much faster than # actually copying the file. This is problematic only if something modifies # the mail in one folder but doesn't want it modified in the others. I don't # know any MUA which would modify mail files directly. IMAP protocol also # requires that the mails don't change, so it would be problematic in any case. # If you care about performance, enable it. maildir_copy_with_hardlinks = no # Check if mails' content has been changed by external programs. This slows # down things as extra stat() needs to be called for each file. If changes are # noticed, the message is treated as a new message, since IMAP protocol # specifies that existing message are immutable. maildir_check_content_changes = yes # Which locking methods to use for locking mbox. There's three available: # dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe # solution. If you want to use /var/mail/ like directory, the users # will need write access to that directory. # fcntl : Use this if possible. Works with NFS too if lockd is used. # flock : May not exist in all systems. Doesn't work with NFS. # # You can use both fcntl and flock too; if you do the order they're declared # with is important to avoid deadlocks if other MTAs/MUAs are using both fcntl # and flock. Some operating systems don't allow using both of them # simultaneously, eg. BSDs. If dotlock is used, it's always created first. mbox_locks = dotlock # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. mbox_read_dotlock = yes # Maximum time in seconds to wait for lock (all of them) before aborting. mbox_lock_timeout = 300 # If dotlock exists but the mailbox isn't modified in any way, override the # lock file after this many seconds. mbox_dotlock_change_timeout = 30 # umask to use for mail files and directories umask = 0077 # Drop all privileges before exec()ing the mail process. This is mostly # meant for debugging, otherwise you don't get core dumps. Note that setting # this to yes means that log file is opened as the logged in user, which # might not work. It could also be a small security risk if you use single UID # for multiple users, as the users could ptrace() each others processes then. mail_drop_priv_before_exec = no --------- Thanks in advance for any help you can give. - Ian

[Dovecot] Setting up a local shared mailbox
by Peter Clark 14 Sep '03

14 Sep '03

One: I have never set up an IMAP server before, so I thought I would ask first before blindly stumbling around. The problem I am want to solve is this: my wife and I have a "joint" email account that we both want to access (we also have our own personal accounts, but that's beside the point.) I posed the question to my local LUG, and several suggested setting up a local IMAP server so that we can both access it through KMail. Would you concur? If so, is there a tutorial or something similar that gives instructions for setting up dovecot locally? As I said, I've never set up an IMAP server before, and I'm not really sure how to go about it. (I'm running Debian Sid, so the packages are already installed, but I don't know what additional steps need to be taken.) Thanks for your help, :Peter

[Dovecot] Patch for auto-creating home directories
by David S Madole 13 Sep '03

13 Sep '03

I've created a patch that adds a feature that is helpful to my setup. If 'parent_dir_umask' is set in the configuration file, any missing directories in the home directory path are created. The home directory itself is created according to the 'umask' setting, 'parent_dir_umask' is only used for intermediate directories that might need creating. This is useful to me, as I pull user information from a PostgreSQL database. This allows a new account to be created just by populating the database.

[Dovecot] Dovecot on Linux 2.6.0-test1-ac1

I've been using Dovecot on 2.6.0-test1 for quite awhile but today I jumped ahead to test5 and it broke in the way you described. http://dovecot.procontrol.fi/list/dovecot/2003-July/001943.html I used your workaround and now everyone is back in business. Thank you for the help! (I was sweating there for a bit.) --kyler

[Dovecot] Web administration tool
by Timo Sirainen 10 Sep '03

10 Sep '03

Any suggestions for a small web based tool to manage virtual domains/users? I tried to look but didn't really find anything that didn't seem to be tightly integrated with Courier or Cyrus, and I'd rather not spend time writing yet another one of those. I would be using Postfix and Squirrelmail with LDAP or PostgreSQL. On a somewhat related thought, I've been thinking about writing some kind of performance and statistics tool which would at least show the users who are logged in and how much CPU, memory and disk I/O they're eating so that you could see what's happening when load is too high. From Dovecot side that'd be done using a plugin. I'm not sure what the client side would be.. HTML might not be enough. Java maybe. Would Flash be too evil? :)

I have trouble to get my INBOX-mbox to work properly. I have set the default_mail_env, to this..

[Dovecot] still getting weird .{inbox} folder creations with latest -test7
by Charlie Allom 06 Sep '03

06 Sep '03

Hi, I am still getting strange creation and mailbox lookups from 0.99.11-test7. dovecot creates in ~/Maildir/ .INBOX/ .imap.index .imap.index.cache .imap.index.log .customflags dovecot-uidlist .INBOX seems to be a reference to ~/Maildir/{cur,new,tmp} yet I cannot get an IMAP client uo pick up my other maildir, located at ~/Maildir/mi/{cur,new,tmp}. In Apple's Mail.app, it picks up a file called ~/Maildir/.procmaillog as if it were a maildir directory! This is with the Mail.app preference for "IMAP Path Prefix" set to null. mutt just seems plain confused. I have these settings: # imap styleee set folder=imap://yeled@lazy.spodder.com/ set mbox=imap://yeled@lazy.spodder.com/mbox set record=imap://yeled@lazy.spodder.com/sent set postponed=imap://yeled@lazy.spodder.com/postponed set spoolfile=imap://yeled@lazy.spodder.com/ set certificate_file=~/.mutt/certificates set mail_check=10 set timeout=10 set imap_home_namespace="" set imap_pass="foo" I have included the tcpflow files to show what the clients are doing.. Is it normal to search for folders starting with "." ? Why won't it just pick up my normally nested maildir folders? C. -- charlie(a)rubberduck.com - http://rubberduck.com/~yeled/

[Dovecot] dovecot, vpopmail and djb's tcpserver
by Lasse Danielsen 06 Sep '03

06 Sep '03

Hello! I've tried to set up dovecot in conjuction with vpopmail, and running it under djb's tcpserver instead of (x)inetd. Btw - there was no reference to setting dovecot up using (x)inetd either in the manuals/faqs i read, though I didn't search all that hard. Anyway, back to my Q: vpopmail uses vchkpw as an authentication mechanism, and with tcpserver I can do relaycontrol (based on vchkpw) with roaming users. Is there anyone who have tried this, and succeeded? Right now I use two imap services to accomplish this (bincimap has support for vchkpw). Thank you for any response. - Lasse Danielsen Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

[Dovecot] pine, INBOX, and dovecot
by Jethro R Binks 04 Sep '03

04 Sep '03

Hi all, I've been experimenting with Dovecot; tests with Maildir seemed to work fine. However, now I'm trying with mbox folders, and I'm having a problem where I do not get an INBOX listed using pine. Outlook Express and IMP show it fine. I snooped part of the session, which appears to go like this (it is slightly garbled, sorry -- I couldn't get rawlog to work by creating dovecot.rawlog in the mail home directory): 00000002 CAPABILITY\r\n * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UN 00000003 LIST "" %\r\n" * LIST (\NoInferiors) "/" INBOX * LIST (\NoInferiors \UnMarked) "/" "test" * LIST (\NoInferiors \UnMarked) ""/" "Sent Items" * LIST (\NoInferiors \UnMarked) "/" "Drafts" 0000000a OK List .completed.. Pine just displays "test", "Sent Items", and "Drafts". OE happily downloads mail from the inbox I put there, and IMP can see it and read it. Perhaps there is something there that IMAP protocol people might see. Or else, perhaps there is a known reason why pine does this? Any clues would be appreciated - I browsed the list archives but couldn't spot anything very relevant. Pine version is very recent - I updated today to 4.56. Incidentally, is mbox support still broken in the CVS version? Is there an expected timescale for the next release, preferably with mbox fixed again?! Thanks for any advice.

hello, this may be a very stupid question but how do i load a config file? i didn't find the docs part which explains how to start the imapserver at all. i have put this in my xinetd.conf: service imap { disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/local/dovecot/imap flags = IPv4 } and the server is running, but thats all. as u can see i have installed the server in /usr/local/dovecot and i have put the config file in /etc, /usr/local/etc and the programmdir itself - nothing worked. what commands must i write in the xinetd.conf to get the server running ? thanks -- E-Mail by http://www.jesus.ch/ and http://www.livenet.ch/ News, Magazin, Events, Forum, Chat, Free E-Mail, Dialin, Jobs, Top-Newsletter

[Dovecot] observations about delays
by Eric S. Johansson 01 Sep '03

01 Sep '03

I've tried two imap clients (mahogany and Mozilla) and they both have strange delays and weird failures. As a reminder, I am using mbox format mailboxes on the server and client side filtering of messages from the inbox. In both cases when the client fetches messages from the inbox and starts redistributing them, CPU utilization on the imap server goes to around 40 percent for Mozilla and around 90 percent for mahogany. There are long delays on the order of two minutes when filtering messages. or 30 to 50 seconds when opening a mailbox. Other than the performance problems, Mozilla is relatively well-behaved. Mahogany on the other hand is a bit more rough and (not) ready. It uses c-client for its imap code and during the filter driven message redistribution process, it all of a sudden started started complaining about unexpected EOF and I found one corrupted message: on 31/8/03 7:36 pm, Morten Christensen at ipcop-d(a)indbakke.dk wrote: >> These bugs might keep many people from trying a new alpha with >> interesting improvements. >> >> A more detailed help for fixing them after install is needed.

[Dovecot] Crash when searching messages
by Nicolas STRANSKY 01 Sep '03

01 Sep '03

Hi, I've been encountering a crash when trying to use the "Search messages" function with mozilla on a newly indexed/subscribed mailbox. I tryed to search something in "To or CC" and got the following : Sep 1 09:07:13 aster imap(nico): file message-address.c: line 255 (message_address_write): assertion failed: (addr->domain != NULL) Sep 1 09:07:13 aster dovecot: child 15674 (imap) killed with signal 6 In addition, mozilla gives the following message : "Server mail.neo-lan.net has disconnected. The server may have gone down or there may be a network problem" and the search fails. But there was no problem when doing other searches. After trying several different types of searches, the initial one (on TO or CC) worked fine, but the crash is reproducible on an other newly subscribed mbox. -- Nico Si cela fonctionne, c'est obsolète.

[Dovecot] conversion to maildir
by Eric S. Johansson 30 Aug '03

30 Aug '03

is really a royal pain in the butt. most of the conversion tools only do a partial job. mb2md seems to be the best but it does not convert the from line correctly unless you are using exim for an MTA. It also does not get the file status right so everything is written to the new maildir directory. something else that makes the process painful is when you have folders containing mailboxes. And the process is *slow* when you have 2 GB of mail (yes, I will be deleting some soon). looks like I will be debugging and rewrapping this package real soon now.. to relate this to dovecot: this is probably not the job of the imap server but it would be real nice to be able to fit in some sort of a plug-in that could automatically do the conversion on a mailbox as it is opened. it would make migrations trivial easy. give me the ability to use python for plug-ins and I will write such a tool. ---eric

[Dovecot] converting from courier-imap
by Emily 30 Aug '03

30 Aug '03

Hello. I apologize if there is a simple answer to this question, but I haven't been able to figure it out. Our people use various clients (pine 4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and all of them work with courier-imap. But I've become very interested in dovecot after reading about it, so I'm trying it out on another server. The results are mixed. Strangely enough, squirrelmail 1.4.1 works wonderfully. For some reason, it duplicates Sent, Drafts, and Trash, but I deleted the duplicates and it was fine. Mozilla messenger is also fine, but with the same duplication of those special folders. Everything seems nice and fast. But some of our users still cling to pine, which works with courier-imap using these three lines in .pinerc: inbox-path={our.server.edu/ssl/novalidate-cert/user=emily}INBOX default-fcc={our.server.edu/ssl/novalidate-cert/user=emily}INBOX.Sent folder-collections="IMAP Folders" {our.server.edu/user=emily/ssl/novalidate-cert}INBOX.[] On the test server I'm using dovecot-0.99.10 compiled against openssl-0.9.7b in Redhat 9. This pine configuration worked in courier, but when I try pine with dovecot, I can't see any folders under "Folder Collection" other than those special three (Drafts, Sent, Trash). I'm sure there's just something I'm doing wrong, but I couldn't find anything in the dovecot list archives. I would appreciate any advice on what I'm doing wrong in getting pine to see the whole collection. Thanks, -- Emily

[Dovecot] No localhost after reboot
by Bob Hall 30 Aug '03

Rebooted the server box today. Now Dovecot doesn't listen at localhost. It does listen at the LAN interface, so it is perfectly usable, but... Does anyone have any idea why it has stopped listening at localhost? Bob Hall

[Dovecot] Postgresql and Dovecot
by Michael Ducy 29 Aug '03

29 Aug '03

I am having some issues getting dovecot to work with postgres. Dovecot starts up and runs fine without using postgres (ie passwd and pam). There is nothing in /var/log/messages other than: Aug 28 12:44:05 mail dovecot: dovecot startup succeeded Then ps -A shows no running dovecot processes (or the imap-login or pop-login). I have tried with both the RPMs that are on the download page and buidling it myself on 2 different boxes (yes I configured with --with-pgsql - Red Hat 7.3 and Red Hat 9.0). Any suggestions would be appreciated as this is the only imap/pop server with pgsql support and flatfile support I can find. Michael

[Dovecot] better body and text search?
by Mark Anderson 29 Aug '03

29 Aug '03

(this is a resend, sorry if duplicate but my first post didn't get through). I was wondering what plans dovecot has for text and body search? This is one of those issues that *no* imap implementation ever seems to document :(. Not cyrus, courier, bincimap, or dovecot.... i speed-read some of the sources and found src/lib-mail/message-body-search.c After a quick scan, it seems: - it uses no text index at all, but does a linear search over the folder. - it searches only messages with content-type starting with "text/" or "message/" - it does no special parsing of "text/html", so tags and attributes would match - it appears to exclude any mime messages, since it skips "multipart/mixed" for example. - it does deal with content encoding and charset. There is a lucene-based text indexing utility for IMAP stores here: http://www.tropo.com/techno/java/lucene/imap.html But ideally there would be pluggable text indexing builtin.... -mda

[Dovecot] Custom flags.
by Maheshkumar Sabhnani 29 Aug '03

29 Aug '03

How do I define custom flags? What are added features of IMAP apart from Online access and Hierarchy folders. I created a new folder and copied couple of messages from incoming file. Where is this new folder created? Also Microsoft Outlook still shows the messages in incoming as deleted. How do I refresh list to permanently delete the messages that I have already transferred to a different folder. Mahesh

Hello, I am having problems with configuring dovecit. The imap directory was correctly made in ~/mail/.imap But I can't see any mail headers. My mbox path is ~/mail/incoming Currently I am trying to use "mbox:~/mail/:INBOX=~/mail/incoming" for configuration but it complains about missing value. Can someone send me more information on configuration directives especially mbox and INBOX. Early reply shall be appreciated. Regards, Mahesh

Not cyrus, courier, bincimap, or dovecot.... i speed-read some of the sources and found src/lib-mail/message-body-search.c After a quick scan, it seems: - it uses no text index at all, but does a linear search over the folder. - it searches only messages with content-type starting with "text/" or "message/" - it does no special parsing of "text/html", so tags and attributes would match - it appears to exclude any mime messages, since it skips "multipart/mixed" for example. - it does deal with content encoding and charset. There is a lucene-based text indexing utility for IMAP stores here: http://www.tropo.com/techno/java/lucene/imap.html But ideally there would be pluggable text indexing builtin.... -mda

[Dovecot] mail accounts for users without home dirs
by Gunter Ohrner 28 Aug '03

28 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I use dovecot on a machine where users without an existing home directory (Not my idea...) need to access their mailboxes. Unfortunately dovecot tries to chdir to the users home directory before allowing IMAP access - is there anything I can do about that besides creating a dummy-homedirectory for these users?

[Dovecot] 0.99.11-test6
by Timo Sirainen 28 Aug '03

28 Aug '03

http://dovecot.procontrol.fi/test/ I think I've fixed the problems that were corrupting indexes with the new code. It happened every time you had expunged some messages and new messages arrived. I think this release might actually work :) disable_plaintext_auth = yes will be default from now on. It allows plaintext authentication from localhost (127.*, ::1) however. I just figured out that the lockless cache file reading prevents me from fixing the mbox code to work the same way it used to. I'm not sure actually how this would be best fixed.. Problem is that headers in mails change and move the messages around in the mailbox, so I have to keep track of them. Previously I just updated the header size in index files.. but without read locks this can't be done safely. One possibility would be to parse the whole mbox file every time when the mailbox is opened (or when it needs to be read) and save the header sizes in memory. That'd make it slower than it is today though.. Or maybe it'd work if I just grabbed exclusive lock whenever reading header sizes. They could be then copied into memory to avoid locking more than once. But that still creates locking contention if lots of clients are reading the mailbox. Exactly in the situation where I'd mostly use mboxes.. I could also save it in .imap.index file which still currently uses read-locks. But I'd rather want to get rid of them in there too.

[Dovecot] IMAP error after login
by Nicolas STRANSKY 28 Aug '03

28 Aug '03

Hello, I'm having a slight problem with Dovecot (0.99.10-0.rc2, on Debian woody). When using mozilla 1.4, there is an error message from the mailer just after login, but nothing in dovecot logs. "Alert The current command did not succeed. The mail server responded: Error in IMAP command UID: Too long argument.." How could I fix this problem ? Thanks, -- Nico J'ai une panne de micro et les parasites me brouillent l'écoute

[Dovecot] Chrooting the Mail processes
by Bert Koelewijn 25 Aug '03

25 Aug '03

Hello! Could somebody give some feedback on this configuration: - OpenBSD box with local ssh users. - /home directory mounted with nosuid,noexec. - postfix dropping mail in /home/username/mail/INBOX, with the UID/GID of the user. - dovecot: valid_chroot_dirs = /home default_mail_env = mbox:/home/%u/mail/:INBOX=/home/%u/mail/INBOX Are there any obvious ways for a local user to help dovecot escape the chroot jail? How can I check that dovecot is REALLY using /home as chroot jail for the imap process? Thanks! Bert Koelewijn

[Dovecot] Docs on the wiki
by Bob Hall 25 Aug '03

25 Aug '03

I went to the Dove Wiki page and added a couple of docs. There's a DoveWikiMainPage link at the top of the first page now. Click on that and the next page has links to the two docs. Someone who knows more than I do about wiki formatting should make this look good. The two docs are for Dovecot/OpenLDAP installation. The first is detailed instructions and the second is a cheat sheet. You don't need to contact me if you find errors; just click "Edit this page" at the bottom. Anyone who wants to use parts of my docs to use in documenting other types of installation should feel free. There's no mention of copyright policy, but I assume everthing is GPL copyleft. Bob Hall

[Dovecot] Postfix and Maildirs
by Steve Sloan 24 Aug '03

24 Aug '03

Hope someone can help me with this as I am presently stuck I am setting up a new server with Dovecot 0.99.10, Redhat 9.0, Postfix, Amavisd-new and maildir's in the users home drive. I am using Netscape mail 7.1 as the main client to access the mail store via imap which works fine and various other imap clients can access the maildirs Ok as well. The problem is when Postfix delivers a message is insists on making a second Maildir directory in the user's home drive and put the message in there. The Maildir's are being created automatically ie. I didn't use maildirmake. Even if I delete one of the Maildir's it just gets recreated again. ie. this is the test user's home drive drwx------ 10 test2 test2 4096 Aug 23 20:53 Maildir drwx------ 6 test2 test2 4096 Aug 24 11:05 Maildir This is the Maildir that the clients are using and being accessed by Dovecot drwx------ 10 test2 test2 4096 Aug 23 20:53 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 23 19:58 cur -rw------- 1 test2 test2 5 Aug 23 19:58 .customflags drwx------ 5 test2 test2 4096 Aug 23 19:59 .Drafts drwx------ 2 test2 test2 4096 Aug 23 19:58 .INBOX drwx------ 2 test2 test2 4096 Aug 23 19:58 new drwx------ 5 test2 test2 4096 Aug 23 20:15 .Sent -rw------- 1 test2 test2 29 Aug 23 20:13 .subscriptions drwx------ 5 test2 test2 4096 Aug 23 20:11 .test drwx------ 2 test2 test2 4096 Aug 23 19:58 tmp drwx------ 5 test2 test2 4096 Aug 23 20:11 .Trash and the other one which Postfix user's drwx------ 6 test2 test2 4096 Aug 24 11:05 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 24 11:05 cur -rw------- 1 test2 test2 5 Aug 24 11:05 .customflags drwx------ 2 test2 test2 4096 Aug 24 11:05 .INBOX drwx------ 2 test2 test2 4096 Aug 24 11:05 new drwx------ 2 test2 test2 4096 Aug 24 11:05 tmp This one has no index files and looks just like a courier Maildir For Postfix main.cf I have set home_mailbox = Maildir/ and /etc/dovecot.conf default_mail_env = maildir:/home/%u/Maildir Hope this make sense to someone Steve -- _____________________________________________ LanSol Computers 283 Sir Donald Bradman Drv.

[Dovecot] Three oddities
by Bob Hall 24 Aug '03

24 Aug '03

FBSD 4.8, Dovecot-0.99.10 1) I have mail accounts for people who use Macs and Windows, so their mail is stored on a Unix box where they don't have accounts. When their mail comes in, it is stored in /var/mail/<accountname>. When I was setting this up, I used my own Unix account for testing, and that works fine. But for the other mail accounts, which don't correspond to Unix accounts, I want to give ownership of the /var/mail/* files to another account that doesn't have my privileges. However, no one can access their mail unless I own their files. As long as I own all the /var/mail/* files, everything works fine. But if I shift ownership to another account, users can log on to Dovecot but attempts to access an IMAP folder return an error. >From maillog: Aug 18 16:39:46 kongemord imap(philrodrigues): mkdir_parents(/var/mail/philrodri gues/.imap/INBOX) failed: Permission denied All files and directories in /var/mail/* are in the mail group. I tried adding dovecot to that group, but that didn't help. Since everyone can log on to Dovecot, but can't access their mail unless I own their files, I'm assuming that there's some simple ownership setting that I'm overlooking. But I haven't a clue what it is. Can someone tell me what I need to change? 2) The Macs have Eudora 4.2 installed, and the Win boxes have Eudora 5.1. The Macs can delete mail, put it in the trash, and empty the trash. The Win clients can mark mail deleted, but they can't remove it. The mail stays in the IMAP folder until the same user accesses their mail from a Mac and deletes it. If a user drags a message to another folder, a copy is created in the new folder but the old copy remains in the original folder. I'm not having this problem with Mutt, so it the problem seems to be specific to the Windows verson of Eudora. Is there a fix? 3) We're pulling our e-mail off our ISP's POP server and loading it into Dovecot to allow people to work with their mail from different machines. I'm using getmail to make the transfer. Is anyone else doing POP to IMAP, and how are they doing it? Any suggestions? TIA, Bob Hall

[Dovecot] user database clarification
by Jared 22 Aug '03

22 Aug '03

Hi, this question gets back to a thread I started back on July 8th. (gosh how time flies) I still am not clear on why PAM is not supported for the user database. I'm in an environment that has users both in local flat files (/etc/passwd and /etc/shadow) AND in an LDAP database. Is it possible for this set up to work with dovecot? (both local and ldap users have imap/pop?) I'd prefer to just have Dovecot use PAM for user db and the password database so that I can configure PAM to try both local users and LDAP users. Thanks a lot. -jared

[Dovecot] rawlog change suggestion

I find the separate .in and .out files rather difficult to work with. I think it would be more useful if the in/out traffic were interleaved with a prefix to indicate direction, and suffix to indicate continuation, as recordio (http://cr.yp.to/ucspi-tcp/recordio.html) does: <a0002 LIST "" "" >* LIST (\Noselect) ";" "" >a0002 OK List completed. <a0003 SELECT "INBOX" >* FLAGS (\Answered \Flagged \Deleted \Seen \Draft) >* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags + >permitted. >* 18 EXISTS >* 0 RECENT >* OK [UNSEEN 18] First unseen. >* OK [UIDVALIDITY 1055795174] UIDs valid >* OK [UIDNEXT 6741] Predicted next UID >a0003 OK [READ-WRITE] Select completed. <a0004 STATUS "incoming.foo" (RECENT) >* STATUS "incoming.foo" (RECENT 397) >a0004 OK Status completed. <a0005 NOOP >a0005 OK NOOP completed.

[Dovecot] Mozilla dovecot interaction
by Eric S. Johansson 21 Aug '03

21 Aug '03

I think this is more a Mozilla bug but just a heads up the case other people complain. periodically, the Mozilla e-mail client refuses to delete messages. It shows up either as absolutely no action when you press the delete key/button or it shows activity but refuses to perform any other action in that mailbox. Sometimes if you switch to another mailbox and then come back to the mailbox you're deleting e-mail message from, the messages deleted when you re-enter the mailbox. I looked with ethereal and it looks like Mozilla is not sending any imap commands. Hence my assertion that it's a Mozilla problem. The only reason I mention it here is because something about dovecot seems to trigger the problem more quickly. I was seeing this kind of problem before but only after a week or two of uptime in the browser. Now I'm seeing it in just under a week (I think) I've only seen at once but I will keep track for future reference. I got to get me a new client... ---eric

[Dovecot] transitional weirdnesses
by Eric S. Johansson 20 Aug '03

20 Aug '03

1) not reproducible but when it occurred, its stuck: in the early transition to dovecot I would notice occasionally that messages would come up, I would delete them and then something would hang causing a major delay in the (Mozilla) e-mail client's response. When the system responded, I would notice that occasionally there would be an off by one offset between the index of messages and the message displayed. This error would persist until I killed off the index and the dovecot process. 2) very reproducible: after fetching messages from my inbox, there will be a long (30 sec.) delay. Dovecot demon is clearly busy doing something. I do have a large set of filter rules (approximately 150) sorting messages into different boxes. Is this a reason to switch to maildir? 3) just ended up with a message that displayed the entire header. Will look into this more but it's very strange. ---eric

[Dovecot] Squirrelmail and Dovecot folder namespace
by Warren Togami 19 Aug '03

19 Aug '03

I am currently using Squirrelmail and Dovecot with this setting: default_mail_env = mbox:%h/mail/:INBOX=%h/mail/INBOX It works well, however folder subscriptions in Squirrelmail annoyingly end up with "./" prefixes because Squirrelmail refuses to work without overriding the folder namespace. All of my other IMAP clients work fine without setting that option. Squirrelmail's default setting is this: $default_folder_prefix = './mail'; This setting breaks Squirrelmail: $default_folder_prefix = ''; This setting becomes default if you attempt to blank that user's preference: $default_folder_prefix = './'; The end result of this is duplicate entries in .subscriptions, one with "./" prefix and one without. Most IMAP clients handle this by showing all the folders again in a folder named ".", or Mozilla displays all folders twice. =( When I asked one of the squirrelmail developers, he said that this might be a dovecot specific problem. Any ideas? Warren Togami warren(a)togami.com

[Dovecot] Questions
by Alejandro Martinez 19 Aug '03

19 Aug '03

Hi, I'm still figthing with passwd-file, virtual users and permissions. I have created the directory /var/spool/virtual/test and inside I've done a "maildirmake Maildir". I have a couple of questions : I use the same passwd-file for auth_userdb and as auth_passdb. 1) What program can I use to create the userdb file ? What I do now is to use the htpasswd program and then I complete by hand the rest of the fields (uid:group:GECOS:home:shell) htpasswd userdb test password: xxx again: xxx And then vi userdb test@test.com:ssasZXc00P1H6:502:102::/var/spool/virtual/test/:/bin/false <--by hand. I think that if I want to offer virtual mail with imap is very tedious to complete user by user. (If this second question does not fall in this list, then don't answer it) 2) I know that postfix delivers in Maildir format, and when the user is a virtual user, I do the next Modify the virtual file ---> test(a)test.com test.test.com Modify the aliases file--> test.test.com: /var/spool/virtual/test/Maildir postmap hash:virtual postaliases hash:aliases postfix reload but when I do a "echo testing | sendmail test(a)test.com " I receive an error Aug 18 15:32:44 slk90 postfix/pickup[12208]: 95C3717D5C: uid=0 from=<root> Aug 18 15:32:44 slk90 postfix/cleanup[12252]: 95C3717D5C: message-id=<20030818183244.95C3717D5C(a)slk90.equital.lx> Aug 18 15:32:44 slk90 postfix/qmgr[12209]: 95C3717D5C: from=<root(a)slk90.equital.lx>, size=291, nrcpt=1 (queue active) Aug 18 15:32:44 slk90 postfix/local[12254]: 95C3717D5C: to=<test.prueba.com(a)slk90.equital.lx>, orig_to=<test(a)prueba.com>, relay=local, delay=0, status=bounced (cannot append message to destination file /var/spool/virtual/test/Maildir: cannot open file: Permission denied) I'm confused about permissions.

[Dovecot] more transitional joys

well, now that I have moved to dovecot, I'm not getting any spam... in fact, I'm not getting e-mail at all. default_mail_env =mbox:~/IMap2/:INBOX=/var/spool/mail/%u when I first tried to access my inbox, I was told I had permission problems: Aug 14 17:47:22 harvee imap(esj): open(/var/spool/mail/esj.lock) failed: Permission denied Aug 14 17:47:22 harvee imap(esj): file_lock_dotlock() failed with mbox file /var/spool/mail/esj: Permission denied so I changed permissions on /var/spool/mail to 777 as a temporary work around. no luck.
