[Dovecot] child <pid> (imap) killed with signal 6
by Per-Stian Vatne 02 Oct '04

02 Oct '04

Linux <hostname> 2.6.8-1.541 #1 Wed Sep 1 18:01:46 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux dovecot-0.99.11-1.FC3.3 I'm struggling with some new problems after an update from the devel tree of Fedora. Have been using dovecot since FC1 test-something, and latest working was couple of updates after FC3t2 (2.91 + devel updates). Tried downgrading with no luck, and can't figure out what's wrong. Setup is very standard Fedora, all defaults I guess, using postfix and Maildirs, and dovecot for imap access. What happens is when logging in and authenticated ok, the connection is dropped. To illustrate I've connected directly and showing the (verbose) output: (commands) [xxx@xxxxxxx ~]$ telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. x login imtest <password> x OK Logged in. Connection closed by foreign host. [xxx@xxxxxxx ~]$ (log) dovecot-auth: Oct 02 14:59:32 Info: Login process 7 connected dovecot-auth: Oct 02 14:59:32 Info: Login process 7 sent handshake: PID 10816 imap(imtest): Oct 02 14:59:40 Panic: Trying to allocate 0 bytes imap-login: Oct 02 14:59:40 Info: Login: imtest [::ffff:127.0.0.1] dovecot-auth: Oct 02 14:59:40 Info: Login process 6 disconnected dovecot: Oct 02 14:59:40 Error: child 10818 (imap) killed with signal 6 I've looked around on the web for this error, can't find anything except problems reading index files, so the imtest user is a newly created user which have received one single text message, Maildir is created ok and can be read using mutt or something. So problem is for all accounts, both new, old and empty. Would be guessing some sort of permissions problem but should be running mostly as root in default mode? And the dovecot user seems to be ok and working, directory permissions are corrected at startup if it's wrong, and so on... I'm not an expert, might be something trivial, but cannot figure it out by myself or Google so mailinglists are next. Let me know if I should send some more information about the system. Thanks, Per-Stian

[Dovecot] Dovecot on Cygwin
by espino＠infomed.sld.cu 02 Oct '04

02 Oct '04

Sorry guys I have to ask this one more time. I really need an answer. Have any of you been able to make Dovecot work on Cygwin? Do any of you know about anybody who have had any success on it? I repeat, I'm eager searching for an answer. If it is possible I'll contact the person who achieved it. If it is not possible yet, I'm gonna have to switch. Thanks once more.

[Dovecot] Dovecot/IMP attachment problem
by Ryan Hulsker 01 Oct '04

01 Oct '04

I recently installed dovecot in my production environment. This comprises about 60k mailboxes. The system was initially set up with dovecot 0.99.10.7 using maildirs. I have been using perdition to handle redirection during the process of converting from wu-imap. Last week it was brought to my attention that our webmail interface (horde/imp) is no longer allowing people to download attachments. Everything appears to work fine, however the downloaded files are 0 bytes in size. I built a test box with the latest horde/imp/php combination and that failed to solve the problem. Today I upgraded dovecot on one of our mail servers to 0.99.11 and that seems to have had no effect. I was hoping that the BODY and BODYSTRUCTURE changes from 99.10.8 would have fixed this. I am wondering if anyone has encountered these problems? Is this a dovecot bug? Due to the fact that I am still in transition mode using perdition I am in the unique position where I can basically hit two identical mailboxes, one in wu-imap and the other in dovecot just by using a different username. I have done this, and have ethereal traces if anyone is interested in helping me out with this. Ryan Hulsker

Well, the attachments do exist in the mailbox, and sending attachments is no problem. Retrieving attachments through OE->dovecot works, OE->wu-imap works, IMP->wu-imap works, however the combination of IMP->dovecot seems to cause a problem. I have a feeling that IMP is using a different method of retrieving the attachments than OE does, and there is probably something IMP does not like about dovecots responses. I will go through my ethereal traces and see if I can piece together what is going on in more detail. Ryan Hulsker

[Dovecot] Dovecot on Cygwin
by espino＠infomed.sld.cu 30 Sep '04

30 Sep '04

I'mt trying to make Dovecot run on Cygwin. I managed to make it compile and register as a service on Windows XP. I had a problem with setrlimit, but I disabled the process size limitation in the config file. Now, when I start the process, either by clicking the start button on the MS Managemente Console or by cygrunsrv -S dovecot, i get to error dialogs saying that the program needs cygcrypt-0.dll and cygwin1.dll. I have both of those libraries on the system but the program doesn't seem to see them. Do any of you have a clue about this? Thanks. ------------------------------------------------- Este mensaje fue enviado usando el servicio de correo en web de Infomed http://webmail.sld.cu

They are more or less separated already, but I don't know how useful it would be to create a separate library distribution from them. That is what takes most of the space in Dovecot distribution anyway.. Oh, and after v1.0 I'll probably start fixing the mailbox APIs too. lib-index and lib-storage needs to have different kind of relationship. > It would be marvelous if at some point being able to replace c-client > library to your optimized one for PHP, mailsync, postman, aolserver and > others - even if it means loosing support for odd mailbox formats. I'm not sure what kind of API PHP provides for c-client. I know it's commonly used for building IMAP webmails, but Dovecot doesn't have any IMAP client code and maybe never will.

Hello list, I am running Dovecot 1.0-test46 on FreeBSD with PostgreSQL as backend, runs _very_ nice, but i can not set "default_pass_scheme = CRYPT" (only PLAIN) for PostgreSQL Auth in dovecot-pgsql.conf. I have a valid entry in pg_hba.conf (and reloaded/restarted): "local mail mail crypt" If i replace crypt in pg_hba.conf with md5 it works also with plain in dovecot-pgsql.conf? -- Christian.

It's still there, just chagned (and probably for the better - less confusing and I'd venture less code) in 1.0. I had: protocols = imap imaps imap_listen = 127.0.0.1 imaps_listen = * Now I have: protocols = imap imaps protocol imap { listen = 127.0.0.1 ssl_listen = * } However, after encountering the same problem you did I moved my 0.99 configuration file out of place and put the 1.0 dovecot-example.conf file into place and modified it, since that seemed like the easier thing to do (not that the imap section already exists in the new example config., it's just empty). - Michael On Tue, 28 Sep 2004, Kim Culhan wrote: > > Noticed that some configuration settings like > imap_listen appear to have been removed. > > Any way to accomplish this ? > > -kim > > > > > __________________________________ > Do you Yahoo!? > New and Improved Yahoo!

[Dovecot] Dovecot 1.0-test45 indexing issues
by dovecot＠spam.turbolink.net 28 Sep '04

28 Sep '04

We're currently on dovecot 0.99.10 with a few modifications (including one very nasty hack for the blank line at the beginning of the mailbox bug). We're using mbox all around. Everything works smoothly but we still ocasionally get corrupt mailboxes and indexes that need to be wiped out. I setup 1.0-test45 on one of our mailservers to start testing it and ran into a few issues. The first one is if I try to use mail_read_mmaped=yes I get this error: Error: POP3(sobo1): file istream-raw-mbox.c: line 410 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) for every mailbox. If I switch to mail_read_mmaped=no everything works, but performance is extremely bad. I have a few test mailboxes with about 20k messages and if I toggle a message flag from unread to read, dovecot seems to re-read the entire mailbox up to that message (I saw this with strace). Is this how supposed to work?? I don't see behavior like this on 0.99.10, and on a mailbox with any substantial number of messages it really slows things down. Thanks for any input. - Mike

[Dovecot] Moving mail dirs

Hi all, This is probably a silly question, but I have a problem. I've had to move my users maildirs from: maildir:/home/%u/.Maildir To maildir:/data/mail/%u I've updated the MTA to put mail to the correct place and it's working fine. I've also changed the dovecot.conf file and restarted dovecot and I thought that would be all I needed to do. However, the users are getting lots of error messages, and looking in the relevant logs shows lots of entries like: Sep 28 14:03:36 <hostname> imap(<user1>): stat() failed with file /home/<user1>/.Maildir/new: No such file or directory Sep 28 14:03:36 <hostname> imap(<user2>): utime() failed with index file /home/<user2>/.Maildir/.INBOX/.imap.index: No such file or directory (Sorry for changing usernames and hostname, but I'm neurotic about that kind of thing) What have I missed?

[Dovecot] Thunderbird 0.8 - Inbox grayed out and does not update
by Sitapati das 27 Sep '04

27 Sep '04

Hi all, I cannot get Thunderbird 0.8 to work with my dovecot IMAP server. It works fine with my work IMAP account - I'm not sure what they are using. What happens is that folders that I create in Thunderbird or Evolution can only contain subfolders or messages, not a combination of both. Folders which contain subfolders and not messages show up in Thunderbird grayed out. I can expand them and view the subfolders and the messages within those. The Inbox however, also shows up grayed out. When I look inside I can see the messages that were there when I created the IMAP account in Thunderbird, however, no new messages arrive, even after restarting Thunderbird. If I connect with Evolution 1.4 I can read the inbox without a problem. Has anyone seen this? warm regards, Joshua

[Dovecot] Concerned about Dovecot's new NTLM code
by Andrew Bartlett 26 Sep '04

26 Sep '04

I'm pleased to see another project increasing compatibility with windows clients, by the addition of NTLM login support, but I'm a bit worried about a few implementation details, and hope to offer an alternate approach. I mean no disrespect to those who have implemented to the code so far, but I feel that the idea of 'everybody re-implement NTLM' is prone to failure. Firstly, to bugs I've noticed by casual inspection of your implementation: - Unicode support is by 'null padding' - there is no real support for non-ascii characters. - NTLM2 (a negotiated scheme to avoid sending the LM response) is unsupported - NTLMSSP is NDR, not 'C struct pushed to the wire', it needs to be correctly marshaled and unmarshaled. There are other missing features, some of which are rumoured to become mandatory flags in future, but more importantly, because the implementation is standalone, it has no ability to integrate into an NT/Win2k/Samba domain. As part of the Samba team, I have worked with other projects - Squid in particular, to deliver server-side (and client-side) NTLMSSP authentication, without the need to re-implement the NTLMSSP protocol. This is done by a callout to 'ntlm_auth', a Samba 3.0 utility designed for this purpose, which in turn can contact domain controllers, allowing for seamless single sign on. http://samba.org/samba/docs/man/ntlm_auth.1.html I have recently completed reworking mod_ntlm_winbind for a similar purpose, and have patches for cyrus-sasl in my 'lorikeet' subversion repository. These should serve as good examples for the simple fork()/exec() modal that is used, and also show the support for GSS-SPNEGO (aka HTTP Negotiate) that ntlm_auth also provides. http://download.samba.org/ftp/unpacked/lorikeet/trunk/ My hope is that I can tempt a Dovecot developer to take on the challenge of modifying the dovecot to use ntlm_auth, and am most willing to answer any questions (here, by private mail or on the samba-technical list) that you may have on the issue.

[Dovecot] problems with cvs version and vpopmail
by Kristoffer Ek 24 Sep '04

24 Sep '04

Hi, I have tried compiling the latest cvs version of dovecot on my FreeBSD 5.2.1-release box with the ports version of vpopmail: 5.4.3_1. In the configuration file I have two auth paragraphs, one for passwd authentication and one for vpopmail-auth: auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail } But the vpopmail dosn'nt work. I got the folowing in the log: Info: auth(vpopmail): vpopmail(stoffer(a)test.ek.dk): unknown user (stoffer(a)test.ek.dk) When I ktrace the dovecot process, it seams that it is trying to access the mysql db, but it ignores the settings in ~vpopmail/etc/vpopmail.mysql If I use the ports version of dovecot it works, but of course without the multiple auth capability since it is version 0.99... Any hints on debugging? - kristoffer -- 1st graffitiist: QUESTION AUTHORITY! 2nd graffitiist: Why? Kristoffer Ek http://ek.dk/ +45 20 40 00 05

[Dovecot] more verbose debugging with test45
by Kim Culhan 24 Sep '04

24 Sep '04

Greetings- Is there any way to increase the logging output of dovecot ? I've set auth_verbose and auth_debug = yes The only output is a single line to syslog mail.info: Sep 23 09:01:54 server dovecot: pop3-login: Login: me [ip.is.here.00] test45 doesn't appear to have the --rawlog configuration option There is nothing written to ~/dovecot.rawlog Tried setting ~/dovecot.rawlog mode to 777 Running FreeBSD-5.3 and dovecot-1.0-test45 dovecot is using passwd auth and pop3s for test purposes and appears to be working correctly otherwise The reason I think I need this is that I don't feel comfortable putting this into production as it is a 'black box' at this point, without a little more testing.. Any help here would be very greatly appreciated -kim __________________________________ Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish. http://promotions.yahoo.com/new_mail

[Dovecot] 1.0-test46
by Timo Sirainen 24 Sep '04

24 Sep '04

http://dovecot.org/test/ Most importantly added mbox_lazy_writes option, enabled by default. This makes Dovecot do writes to mbox only with EXPUNGE and CHECK commands and when mailbox is being closed. This is the same behaviour as with UW-IMAP. Especially useful for POP3 where most users just download the mails and delete everything - with this enabled Dovecot doesn't anymore go writing X-UID headers and whatever. Be careful anyway with this release, it seems to be working with me but mbox can get corrupted from simple mistakes. Other important fixes include: - handle UIDVALIDITY changes in mbox correctly - we might have overridden others dotlock files if they were being rapidly recreated with different processes - should fix syncing read-only mboxes (maybe dovecot.org finally stops giving internal errors :) - fixed several other mbox syncing issues which were quite rare without lazy writing - when sending lots of non-mail data to IMAP clients, Dovecot might have lost some of it causing weird problems. With pop3 it crashed with assert instead of losing data.

[Dovecot] Questions about mail process chroots
by Brett Smith 22 Sep '04

22 Sep '04

Greetings, I am configuring a new Dovecot installation, and the way the valid_chroot_dirs and mail_chroot variables affect the mail processes are a bit unclear to me. I was wondering if anyone could provide me with more specific details than the comments in the configuration file do, or maybe even recommend some values given my configuration. We have a Debian GNU/Linux system and a mix of users with shell accounts and users with disabled logins. Both these groups should be handled the same way by Dovecot: auth_userdb is passwd and auth_passdb is pam. The dovecot PAM service will use pam_mysql.so, if that matters. Mail is in mbox format (we have too many sticklers who are set in their ways, unfortunately); I'm thinking default_mail_env should be mbox:~/Mail/:INBOX=/var/mail/%u. So, if I understand correctly, (a) I should set chroots on the mail processes, since some of our users don't have real shell accounts, and (b) those processes will need access to /var/mail and home directories under /home. So my best guess is that I should set the chroot variables like this: valid_chroot_dirs = /var/mail:/home mail_chroot = /var/mail I'm not sure about this though, for a number of reasons. Do I need to even chroot at all, or do I misunderstand the comments? If I do need to chroot, the comments about valid_chroot_dirs warn very strongly that the chroot dirs should not be writeable by users. /home itself isn't writeable by users, but obviously their home directories are. Is listing /home also vulnerable to exploits? If it is, what would a good solution be? What's the meaning of /./ in mail_chroot? The comments about it, unfortunately, make no sense at all to me. It says that /home/./user is the same as /home, but if that's completely true, why wouldn't I just say mail_chroot = /home? I even looked into the source and it still wasn't really clear to me. Thanks in advance for any help you can offer, -- -- Brett Smith

[Dovecot] Lost messages with Mozilla and dovecot 0.99.x
by John Peacock 22 Sep '04

22 Sep '04

I have just moved our corporate e-mail over to qmail/dovecot and am very happy with the performance. However, I have had two reports of messages going missing which may or may not be directly related to Dovecot. I was able to observe this in action this morning: 1) I got the user out of their e-mail client (Mozilla 1.7.2) and forced an email to be delivered. It showed up in Maildir/new. 2) I had the user log in using our webmail (Squirrelmail) and the message was visible to the client (and correctly moved to Maildir/cur). 3) The user then logged in using the Mozilla mail client and not only was the message not visible in the client, it was no longer on the disk! 4) This was completely repeatable, even if I deleted the .INBOX/index files and forced dovecot to rebuild. For the moment I am thinking this is a client problem, but I thought I'd mention it just in case it rang a bell with someone. I wound up installing 0.99.11 just for grins (I just moved these people to the new server and don't want to risk 1.00-test yet). I'm also going to look at whatever debugging messages are available in dovecot; it would be useful to see a log of all imap transactions, not just login, so I could confirm that it is the client process requesting that the files be deleted and not somethink with dovecot itself (or some hardware failure).

For some reason I could never reproduce this problem with Linux or Solaris, but with OpenBSD it happened immediately. Stupid problem with marking output buffer empty if it was full and write() returned EAGAIN.

For those of you using Dovecot on Fedora, the noisy syslog is fixed: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124979 I'd suggest getting the pam SRPM from Rawhide (Fedora development tree) and rebuilding, to minimize dependency issues.

[Dovecot] Nested folders
by Melinda Taylor 22 Sep '04

22 Sep '04

hello, I know this is a question that has probably been answered before but I have searched for the answer and am yet to find it. I am running dovecot under fedora core 2 and cannot figure out where I set it so that users can create nested folders. At the moment they can only create one subfolder in most mail clients. however if using squirrelmail they can create nested folders but the folder whicch hosts the subfolders cannot contain mail messages as well as folders. Is this a setting in IMAP or with the mail clients. Many Thanks, melinda

[Dovecot] problems building / starting test40 + test42
by Curtis Maloney 21 Sep '04

21 Sep '04

Hi I was trying to build test40 (and then test42, since it came out in the mean time) on my fresh Solaris 9 box at home, and ran into a few snags. First problem was during the build. Make spat the dummy in the auth directory: Making all in auth make: Fatal error in reader: Makefile, line 701: Unexpected end of line seen Current working directory /home/pkg/dovecot-1.0-test42/src/auth So, I went and checked it out, to find what certainly looked to me like an error: 697:distclean-generic clean-generic maintainer-clean-generic clean \ 698:mostlyclean distclean maintainer-clean 699: 700: checkpassword-reply.c 701: 702:# Tell versions [3.59,3.63) of GNU make to not export all variables. Originally, I tried tacking that onto the end of the preceding list, but when the next problem came about, I tried commenting it out... with no joy. The next problem was in starting it. I've configured Dovecot before, and it runs great, keeping all the users at my work happy and supplied with spa... erm... e-mail. I also have an older test version installed on an old SparcStation 5 at home. But when I try to start it, it complains of not being able to drop root group privileges. I googled about for a bit, and found mention of ensuring the minimum GID level was set right... but still no joy. I'm at a loss. Any suggestions? Any requests for better info to help debug? -- Curtis Maloney cmaloney(a)cardgate.net

[Dovecot] Trying to install Test43 with rpmbuild
by Benjamin J. Weiss 20 Sep '04

20 Sep '04

Hi! I'm using WhiteBox Enterprise Linux 3.0, which is a re-compile distro of RedHat Enterprise Linux 3.0. I'm installing a new mail server and would like to use dovecot as it supports Maildir, which the default imapd does not. I've downloaded test43's tarball, and would prefer to use RPM to manage it. To that end, I've tried to do an rpmbuild, but get an error: [root@www src]# rpmbuild -ta dovecot-1.0-test43.tar.gz error: line 7: Illegal char '-' in version: Version: 1.0-test43 I tried untaring the tarball and looking at the dovecot.spec file, and sure enough on line 7 is a reference to "Version: 1.0-test43". The problem is that if I take out the '-', and try rpmbuild, I get more errors. I'm not an expert in this stuff...has anybody else managed to get this working? It would sure make my life easier (I think). Ben

[Dovecot] Weird behaviour with multiple accounts pointing to same maildir
by Bill Moran 17 Sep '04

17 Sep '04

I'm finding this a little strange. I'm putting together a mail server that will (someday, hopefully) serve a lot of email addresses for a lot of domains. To make life easy, each account name is the full mail name ... i.e "joe(a)domain.com" instead of just "joe" Mail is stored in Maildirs, and the user account information is all in MySQL. Delivery is handled by Postfix. Everything seems nice and clean, except ... If I create multiple accounts that all use the same Maildir for delivery (i.e. joe_smith(a)domain.com, js(a)domain.com, js(a)otherdomain.com) it seems to work well. Except that the user can _only_ log in as the first record in the database via IMAP. (i.e. in the example above, the user could log in as joe_smith(a)domain.com, but not the others) Logging in as the others does not produce any erros (that I can find, anyway) but the user can't see his/her mail. I'm rather stumped as to why this is happening. Each record in the database that points to a particular Maildir is identical except for the userid. In the example above, logging in as the 2nd or 3rd account shows folders created, but not the mail in them. For example, the above db records would look like: +----------------------+----------+-----------------------------+-----+-----+--------+ | userid | password | home | uid | gid | active | +----------------------+----------+-----------------------------+-----+-----+--------+ | joe_smith(a)domain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | | js(a)domain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | | js(a)otherdomain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | I'm assuming this is some sort of bug, but if I'm wrong, please correct me.

[Dovecot] Logging IMAP transactions
by Kenneth Porter 17 Sep '04

17 Sep '04

Mulberry has the ability to log the IMAP exchange client-side. Is there an equivalent logging feature in Dovecot (0.99) to log the IMAP exchange server-side? My problem is that Mulberry is displaying some complex MIME structures incorrectly (eg. nested/forwarded messages) but it seems to go away if I close a folder and re-open it. I'm suspecting that Dovecot is reporting the wrong structure on first access and then fixes something on subsequent accesses. I'd like to log the FETCH result with the structure information to see if I can spot this happening.

[Dovecot] Fedora Core 2, dovecot, and Outlook Express
by Joe Hartford 14 Sep '04

14 Sep '04

After the aging harddrive in my Redhat 7.2 server died, I decided it was time to upgrade. I bought a new harddrive and did a fresh install of Fedora Core 2. I've managed to get www, ssh and sendmail reconfigured, but I'm having a heck of a time with imap. I first fooled around with cyrus-imapd, and couldn't make head or tail of it, so I downloaded a fedore core 1 imapd rpm and installed it. That almost worked, but I could only see the INBOX. Next I tried dovecot. Via Outlook Express from my winXP box, I can Refresh the IMAP folder list, and see the INBOX and the sent-mail and saved-messages folders that were created when I first ran pine. However, if I try and mark sent-mail or saved-messages as Visible, I get an "Invalid mailbox name: saved-message/" error. And when I try and view the contents of Inbox, I get "Mailbox doesn't exist: INBOX/". I tried running evolution on the server, and I could subscribe and view the INBOX. But when I try and make a new folder, it gives me a "Cannot create the specified folder. Generic error" I'm hoping I just have something misconfigured, potential due to messing around with cyrus-imapd and imapd, or perhaps even pine. Anyone have any suggestions? I'm pretty close to giving up on fedora core 2 and installing core 1, or perhaps mandrake. --Joe Hartford

[Dovecot] ok, one last time with mbox vs. maildir
by Brian Hechinger 13 Sep '04

i'd *really* like to get to maildir. so here it is, one last time.... using 0.99.x, can i have an mbox spool file and Maildir folders? for just one account? if i can do that, then it'll be a lot easier to transition the whole mess to Maildir. i use procmail called from postfix to deliver mail. is that going to be an issue for delivery? if i don't set DEFAULT and just change all my sort rules to deliver to Maildir folders then i can have it continue to deliver mbox to the inbox-spool and Maildir to the folders? -brian -- "The cats tend to administer themselves, and contrary to the expected facts, the house and everything in it was installed for their benefit." -- Nic Clews
