[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] New installation questions
by Jason Parsons 29 Dec '03

29 Dec '03

Howdy. I'm trying to get dovecot working on Solaris 9/sparc. I'm using LDAP as an authentication backend. After running dovecot and attemping an imap login, I'm getting this message: imap-login: Dec 29 01:52:29 Fatal: fd_send(4) failed: Bad file number imap-login: Dec 29 01:52:29 Fatal: fd_send(4) failed: Bad file number dovecot: Dec 29 01:52:29 Error: child 22972 (login) returned error 89 dovecot: Dec 29 01:52:29 Error: child 22973 (login) returned error 89 Any ideas what could cause this? Also, I would like to run dovecot using daemontools and qmail-ldap's auth_imap. Is this possible with dovecot? An example supervise/run file would be much appreciated. Thank you. - Jason Parsons

[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

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

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
by Eric S. Johansson 26 Nov '03

26 Nov '03

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
by Matthew Reimer 25 Nov '03

25 Nov '03

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. Works for me without the need for patches (though something like SSLCACertificateFile would be nice). Matt

[Dovecot] mbox format
by DINH Viet Hoa 25 Nov '03

25 Nov '03

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.

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] 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] MySQL patch + Debian
by James Tyson 17 Nov '03

17 Nov '03

Hi folks. Sorry to post here about a patch that hasn't been officially integrated into Dovecot, however I am trying to get it going and seem to have hit a dead end. I downloaded the Debianised source for Dovecot (0.99.10-9) from sarge: > wedge:/usr/local/src# apt-get -t testing source dovecot then applied the latest MySQL patch that I could find on the list: > wedge:/usr/local/src/dovecot-0.99.10# cat ../dovecot-mysql.patch | > patch -p 2 and manually fixed a merge issue with src/auth/master-connection.c, fiddled with the debian changelog to indicate the patch and then used dpkg-buildpackage -b to compile the package. Everything looked to build alright and I grepped the output to make sure that it compiled userdb-mysql.o and passdb-mysql.o into dovecot-auth. Problem is that dovecot-auth says "Unknown userdb type 'mysql'" and an ldd of /src/auth/dovecot-auth shows no libmysqlclient10: > wedge:/usr/local/src/dovecot-0.99.10# ldd src/auth/dovecot-auth > libpam.so.0 => /lib/libpam.so.0 (0x4001a000) > libldap.so.2 => /usr/lib/libldap.so.2 (0x40022000) > libpq.so.3 => /usr/lib/libpq.so.3 (0x4005a000) > libcrypt.so.1 => /lib/libcrypt.so.1 (0x4006e000) > libdl.so.2 => /lib/libdl.so.2 (0x4009c000) > libc.so.6 => /lib/libc.so.6 (0x4009f000) > liblber.so.2 => /usr/lib/liblber.so.2 (0x401cd000) > libresolv.so.2 => /lib/libresolv.so.2 (0x401da000) > libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x401ec000) > libgnutls.so.7 => /usr/lib/libgnutls.so.7 (0x401fe000) > libssl.so.0.9.7 => /usr/lib/i686/cmov/libssl.so.0.9.7 > (0x40231000) > libcrypto.so.0.9.7 => /usr/lib/i686/cmov/libcrypto.so.0.9.7 > (0x40260000) > libkrb5.so.17 => /usr/lib/libkrb5.so.17 (0x40351000) > libnsl.so.1 => /lib/libnsl.so.1 (0x40387000) > /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) > libtasn1.so.0 => /usr/lib/libtasn1.so.0 (0x4039c000) > libgcrypt.so.1 => /usr/lib/libgcrypt.so.1 (0x403aa000) > libz.so.1 => /usr/lib/libz.so.1 (0x403e8000) > libcom_err.so.1 => /usr/lib/libcom_err.so.1 (0x403f7000) > libkrb.so.1 => /usr/lib/libkrb.so.1 (0x403f9000) > libasn1.so.6 => /usr/lib/libasn1.so.6 (0x40415000) > libroken.so.16 => /usr/lib/libroken.so.16 (0x40435000) > libdb3.so.3 => /usr/lib/libdb3.so.3 (0x40445000) Anyone know what I'm missing? --- James Tyson Director, Giant Robot Ltd http://www.giantrobot.co.nz/

[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? Many thanks, Scott Klein -- Scott Klein Web Publisher/Director of Technology The Nation Magazine http://www.thenation.com

[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?

[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] 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
by Tom Allison 04 Nov '03

04 Nov '03

I was digging through some of the archives and ran into someone who was having the same problem, but for completely different reasons....i think. dovecot: Nov 02 07:58:51 Info: Dovecot starting up dovecot: Nov 02 07:58:52 Error: Auth process died too early - shutting down dovecot: Nov 02 07:58:52 Error: child 27673 (login) killed with signal 11 dovecot: Nov 02 07:58:52 Error: child 27672 (login) killed with signal 11 dovecot: Nov 02 07:58:52 Error: child 27671 (login) killed with signal 11 dovecot: Nov 02 07:58:52 Error: child 27670 (auth) killed with signal 11 So I took the advice posted and ran 'strace dovecot' and this is what I got. Unfortunately I'm not exactly good enough with this to even know what I'm looking at.

A little more information: This bug results in Mozilla and pine never rendering the message, since dovecot lies about how much data was really sent, as seen in the following log in which only 394 bytes (rather than the 10240 dovecot is claiming to send) are returned: ---- 8 UID fetch 94 (UID RFC822.SIZE BODY[]<10240.10240>) * 24 FETCH (UID 94 RFC822.SIZE 20873 BODY[]<10240> {10240} G 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-- ) 8 OK Fetch completed. ---- Matt

[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.

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

Hello! I've just subscribed and I'd like to ask. Is there any troubles if I change my imap-uw with davecot? Will davecot pick up imap-uw created folders (mboxes)? I use all protocols: imap, imaps, pop and pops. I've seen some problems with mbox was mention on this maillist. What kind of problem? -- Sem.

[Dovecot] problem getting mail from mbox

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. The dovecot.conf files are essentially identical -- the only changes are the names of the SSL certificates and the name of the dovecot user. What I can't figure out is, why is the ordering of the mailboxes different? This is the Maildir directory list: [network:/Users/foc/Maildir] root# ls -al /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/ total 816 drwxrw---- 22 marlier staff 748 Oct 13 19:52 . drwxr-xr-x 64 marlier staff 2176 Oct 10 14:08 .. drwxrw---- 13 marlier staff 442 Oct 13 19:14 .Deleted Items drwxrwxr-x 9 marlier staff 306 Oct 13 19:14 .Dovecot drwxrw---- 12 marlier staff 408 Oct 8 12:26 .Drafts drwxrw---- 7 marlier staff 238 Oct 13 19:28 .INBOX drwxrw---- 13 marlier staff 442 Sep 16 22:59 .Jen drwxrw---- 13 marlier staff 442 Oct 13 18:30 .Klimas List drwxrw---- 13 marlier staff 442 Oct 13 17:57 .Rachel drwxrw---- 13 marlier staff 442 Oct 13 19:14 .Sent Items drwxrw---- 13 marlier staff 442 Oct 13 19:16 .UCCS -rw-rw---- 1 marlier staff 5 Sep 15 20:58 .customflags -rw-rw---- 1 marlier staff 120 Oct 13 18:16 .subscriptions -rw------- 1 marlier staff 296206 Oct 13 19:40 bincimap-cache -rw------- 1 marlier staff 534 Sep 22 17:45 bincimap-subscribed -rw------- 1 marlier staff 197 Sep 16 21:38 bincimap-subscribed.old -rw------- 1 marlier staff 59 Oct 13 19:40 bincimap-uidvalidity drwx------ 3582 marlier staff 121788 Oct 13 19:36 cur -rw------- 1 marlier staff 96421 Oct 13 19:36 dovecot-uidlist drwx------ 2 marlier staff 68 Oct 13 19:36 new drwxrw--w- 2 marlier staff 68 Sep 15 20:58 recov drwx------ 2 marlier staff 68 Oct 13 19:36 tmp [network:/Users/foc/Maildir] root# Any thoughts?

[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.

[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

[Dovecot] those assertions
by Bernard Blackham 05 Oct '03

05 Oct '03

Hi, I did a bit of digging into the assertions from mbox-rewrite.c (hdr_parsed_size.physical_size == hdr_size). Every time it happens, hdr_size is 0, while hdr_parsed_size.physical_size is non-zero (presumably the correct value). Does this help track it down? 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...

[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.

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.

[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!
