Re: [Dovecot] trouble accessing mbox folders with simultaneous logins
by Michael Cosby 04 Oct '04

I can help you narrow the problem down a bit. I'm assuming you're using 1.0-test45 or 46, in which case I see the same problem using mbox, index files stored on disk and no NFS. I access my mail via pine and chatter email (an imap client for the palm). While I've not seen any errors that specifically say UID, the client for the palm will occasionally reload messages from a few days back thinking they're new, which eventually crashes the client when the count of mail it should be loading doesn't match what it actually got (the palm client's in beta, too :) ). I solved the problem by moving back to the 0.99 series, which other than performance issues works just fine for me. - Michael ------------------- In response to: Hi all! I have setup dovecot (RPM) on a Fedora Core 2 machine using LDAP for authentication. It all seems to work pretty well, except for simultaneous logins. I am using mbox files to store the mail as follows (from /etc/dovecot.conf): default_mail_env = mbox:~/.mail/:INBOX=/var/mail/%u:INDEX=MEMORY So the INBOX file is stored in /var/mail, other mailfolders are stored in the users home directory in the .mail folder. Because the /home directory of this machine is mounted from fileserver through NFS, I have set the INDEX=MEMORY options (see http://www.dovecot.org/doc/nfs.txt) As said before I am getting some problems when using simultaneous logins for the same mail account (for instance when multiple users that work on a specific project want to share a mail account containing all the mail about the project in addition to their private account). The client used is Microsoft Outlook and besides some outlook specific problems, it also gives these errors (translated from Dutch) when many users are simultaneously logged in to the same account: 'Your server reported that a UID does not comply with the IMAP standard, which signifies an error on the server.' 'The UID of a message is unexpectedly deleted. This signifies an error on the server.' I am not sure where to look... I assume a problem with the index files? Does NFS cause the problem? Will this be fixed if I switch to maildirs? I would be grateful for any tips on the subject!

[Dovecot] Slow squirrelmail login/IMAP CPU 80%
by rusecure＠rogers.com 04 Oct '04

04 Oct '04

I've been having a problem with Dovecot on Fedora Core 2 with SquirrelMail on the same system. When ever I login through SquirrelMail the imap process consumes around 80% of my CPU and the login takes forever (about 10 minutes). 1 Once I do manage to login, everything is fine and can even log out and back in without issue. Has anyone encountered this? Thanks, Nelson

[Dovecot] Public folders / namespace documentation
by Keith Edmunds 04 Oct '04

04 Oct '04

Does Dovecot support public folders? I thought it may do via namespaces, but having searched the Wiki and the documentation, I can't find how namespaces are defined. I've probably not looked in the right place - any pointers? Thanks, Keith

[Dovecot] using %d in passdb
by leon breedt 04 Oct '04

04 Oct '04

hi, i'd like to seperate the password file for seperate virtual domains into seperate files. i tried specifying: passdb = passwd-file /etc/exim_incoming/local/accounts/pwdb/%d but i get an error message that it couldn't open the particular file, and then Dovecot shuts down. is there a way to do lazy-lookups? or, would i be required to write a little helper program and have Dovecot connect to its socket to do auth? leon

[Dovecot] evolution and received by header
by Dan Stromberg 03 Oct '04

03 Oct '04

Evolution has a nice feature where it can sort messages by the most recent received-by date, instead of the Date: header. This is nice, because then if something gets stuck on a server somewhere in the world for a couple of days, it shows up at the end of your mail list, instead of way back where you might miss it. However, when using dovecot with evo, if I sort of received by instead of date, it takes forever. I assume this is because date is indexed, and received by is not. So the natural question becomes, is there a way of getting dovecot to index received by? TIA.

[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
