[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.
