[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

Sorry, guys for the second message. But I forgot something that may be useful. The first dialog, the one who says "cygcrypt-0.dll" is missing, has "dovecot-auth.exe" as title. And the second one, which says "cygwin1.dll" is missing, has "imap-login.exe" as title. Sorry again. ------------------------------------------------- Este mensaje fue enviado usando el servicio de correo en web de Infomed http://webmail.sld.cu

[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

[Dovecot] Documentation
by Timo Sirainen 30 Sep '04

30 Sep '04

I just wrote two "new user documentation" pages to wiki: http://wiki.dovecot.org/moin.cgi/CompilingSource http://wiki.dovecot.org/moin.cgi/BasicInstall Do you think they are easy enough to understand? Did I miss something? Feel free to edit them directly :) Next should probably come: - Mailbox formats fully explained - Performance tuning
