[Dovecot] imaps, certificate and authentification
by jean-Noël Chardron 07 Dec '04

07 Dec '04

hello, first sorry for my poor english I'm doing the migration from UW-imap to Dovecot I have two question about the authentification in the imaps (port 993) process In dovecot .conf I can enable (or disable) the différent port (pop, pops, imap, imaps) and may be restrict the access to the serveur with the ip adresse. Can I configure dovecot in imaps so it permit the access if the certificate is knowing by the server? Actually, this is the process to authenticate in WU-imap on imaps : the client connect to the server through a tunnel SSL (stunnel) and only if stunnel know the certificate, then the client can connect. and more, Is it possible when the client (with a certificate) connect to the serveur with imaps to authenticate the user without prompting the password, so the authentication is throught the certificate ? These are similar functionnality in the apache server with the restriction access to location et authentification with certificate. thanks -- Jean-Noel

[Dovecot] 0.99.12.1 released
by Timo Sirainen 07 Dec '04

07 Dec '04

The only difference to 0.99.12 is that it now builds without GNU make. I didn't bother to change the version number so it's still 0.99.12 inside the tarball.

[Dovecot] 0.99.12-1.1.fc1.rf broken?
by alex＠amcms.org 06 Dec '04

06 Dec '04

Hi, I dont know if this is a dovecot problem, or the rpm build, me, or my computer ;) Was wondering if anyone else has been having problems using the 0.99.12-1.1.fc1.rf release from http://dag.wieers.com/packages/dovecot/ My specific problem is this. 1. Dovecot starts 2. You can login using telnet 3. You can issue a select inbox but nothing seems to happen By this stage dovecot is spiraling out of control, using up almost all my tiny cpu's processor, when usually it uses basically nothing. What appears to happen if you look at the logs is this. ======= Dovecot Log ======= dovecot: Dec 06 10:39:48 Error: login: Authentication process 5634 doesn't exist ======= Dovecot Info Log ======= imap-login: Dec 06 12:36:09 Info: Disconnected: Inactivity [127.0.0.1] Then, I noticed that if I tried to log in again I would have multiple dovecot-auth processes churning away at my processor.... I went thru the config file, and the new one with my changes, still the same. I also restarted dovecot several times, having to kill all the processes manually as service dovecot stop didnt seem to work. Is anyone else having this problem? And do they know how to fix it? Im running dovecot on fedora core 1, using mysql for authenticating. Thanks Alex

[Dovecot] 1.0 test 52 - test 56 upgrade
by Andrew Hutchings 06 Dec '04

06 Dec '04

Hi guys, I run a LVS cluster system which holds mail via a NFS server in Maildir format, and indexes on the local hard disks. When upgrading from 52-56 about half the index files failed to work correctly, many killing the server. Not really a problem, I just deleted them. Just thought the developer guys should know.

[Dovecot] 1.0-test56
by Timo Sirainen 06 Dec '04

06 Dec '04

http://dovecot.org/test/ - Lots of fixes for mmap_disable = yes. It finally seems to be working pretty well. - POP3 idle timeouts changed to 10min I just wrote a simple stress test tool for IMAP and I've had one for POP3 for some months. The IMAP stress test was very helpful in finding out the bugs I fixed today. If anyone wants to try them, they're in: http://dovecot.org/tools/

[Dovecot] problem with test56
by Cor Bosman 06 Dec '04

06 Dec '04

Hi all, im doing some tests with the test56 release and im seeing some problems with APPEND (may be related to something else, I just see it with APPEND). When I ask someone to move some emails from one mailbox to another, after some messages (seemingly random), the client experiences a 'hang'. When tracing the process what seems to happen is that dovecot doesnt send a final OK after that specific email. It's kinda hard to attach a gdb at that point, so for now, maybe someone has seen this also? Cor

[Dovecot] IMAP - many folders?
by piotr＠mallorn.ii.uj.edu.pl 05 Dec '04

05 Dec '04

Hi, I've been reading the list and it seems the answer to my (soon to be asked question) is no, at least with 0.99, but I'll ask to be sure. I have following setup: new mail goes to ~/Mail/Maildir, except for mailing lists which are moved by procmail to ~/Mail/mailing_lists/name, spam which goes to ~/Mail/spam. Read mail is moved by mutt to ~/Mail/read. Everything is in maildir format. Is it possibile to configure dovecot in such a way to allow user to access all those mail folders thorough imap/pop? User can access ~/Mail/Maildir by setting default_mail_env, but so far nothing else. -- Piotrek irc: #debian.pl Mors Drosophilis melanogastribus!

[Dovecot] 0.99.12-rc1
by Timo Sirainen 05 Dec '04

05 Dec '04

http://dovecot.org/rc/ Just gathered the patches in dovecot.org/patches/ and a few more that I think have been sent to this list before. If there's anything missing, please tell. - Fix memory leaks in LDAP, MySQL and PGSQL userdb/passdb - Fix hanging when parsing mails that have over 4096 bytes in one line (SMTP servers normally don't allow over 1000 bytes so it shouldn't be much of a problem) - FETCH BODYSTRUCTURE sometimes giving a wrong reply (eg. with FETCH (BODYSTRUCTURE RFC822.SIZE) if it wasn't cached) - Never return more than one INBOX in LIST even if there are such files. They don't work anyway and it just confuses clients. - mbox: Don't allow creating INBOX directory by creating/renaming mailboxes under it. They just wouldn't work. - POP3: Don't return PLAIN in SASL list. We don't support initial SASL responses, so it only breaks with most clients that try to use it.

[Dovecot] newbie question
by Grammes, Carsten 03 Dec '04

03 Dec '04

Hello all, just managed to install dovecot as imap server on a Suse Linux box. Now running fine with mbox format. A question regarding maildir or mbox. The MDA (in my case sendmail, Mlocal = procmail) stores mbox format. Do have to modify the local mailer to store maildir format or does dovecot convert automatically from mbox when I tell dovecot to use maildir format? Thanks, for any hint. Carsten

[Dovecot] Maildir/mbox on a per-user basis
by Jon Nathan 03 Dec '04

03 Dec '04

Hello, The Wiki indicates that Dovecot can do either mbox or Maildir on a per-user basis: default_mail_env can be overridden in userdb for each user. This works with userdbs supporting the "mail" attribute (eg. passwd-file, SQL, LDAP). How exactly does one do this for passwd-file? Thanks, -Jon -- Jon Nathan jon(a)rupture.net

[Dovecot] master or client
by Kirill Miazine 03 Dec '04

03 Dec '04

Hello, Dovecot auth protocol 1.0 defines differend command sets for client and master. How can a daemon distinguish a master connection from a client connection? Clients do send CPID and master does not. I have following auth configuration: auth external { socket connect { master { path = /var/state/dovecot/login/master-auth } } } I try to learn my authentication daemon to learn to speak with Dovecot. I fire up my master.py and try to login via pop3 as foo:bar. Below is what my master.py receives from Dovecot (master and client), VERSION commands are not shown: km@thinkpad:/home/km > ./krot/sbin/master.py CPID : ['11915'] CPID : ['11915'] CPID : ['16652'] CPID : ['11915'] AUTH : ['1', 'PLAIN', 'service=POP3', 'secured', 'lip=127.0.0.1', 'rip=127.0.0.1', 'resp=AGZvbwBiYXI='] REQUEST : ['9', '11915', '1'] CPID : ['16652'] (In the above output command and parameters are parsed.) The protocol specification is mentioning a separate SERVICE command in the client's greeting. I can't let my daemon die if the master issues DIE. Why should a server exit when it receives DIE? Can anybody provide an example dialog of an authentication request that is successful and a reques that fails because of a bad password. Thanks, Kirill -- They make a desert and call it peace. -- Tacitus

[Dovecot] pop3 with lmos results in multiple downloads
by Juerd 03 Dec '04

03 Dec '04

One of our users wants to use POP3 with leave-mail-on-server (LMOS). That's great and works well for most people. But for some reason, they MUA (outlook) downloads messages more than once. As the MUA asks for messages, I'm sure it's Outlook's fault, but I was wondering if there is anything that can be done about this on the servern side, or if anyone knows how to fix Outlook. I'm sending this here, because they report that with non-dovecot servers it does work correctly. They do not want IMAP, because they want to use Outlook, which cannot support both Exchange and IMAP simultaneously. This user has multiple accounts, and only for some of them things go wrong. A temporary fix is to remove the mail from the server once, but after a few more messages arrive, the problem starts all over again. Please help. Regards, Juerd

[Dovecot] Problem getting incoming mail to IMAP inbox
by Jeff Sutherland 03 Dec '04

03 Dec '04

I have dovecot-0.99.10.5 on Fedora Core 2 installed and otherwise operating using Maildir format for the folders, Kmail as the email client. Got through all the ssl and other security configuration fine, but have one last problem: I can't read the incoming mail from /var/spool/mail/%u. Tried several 'default_mail_env' settings, including none at all, to no avail. When I try to check in new mail to the inbox, the only messages are "Transmission Complete, no new messages" Tried this setting for example: default_mail_env = maildir:~/Maildir/:INBOX=/var/spool/mail/%u but to no avail. Is something getting cocked up because the folders are all in maildir format and the incoming mail spool is in mbox format? I checked permissions, they seem ok. Kmail can pull the messages in just fine to its local folder inbox, it just seems that dovecot can't read the mail spool file for some reason. All the other maildir folders work fine. ?????????

[Dovecot] Cannot list mailbox
by Fawad Halim 03 Dec '04

03 Dec '04

Hi, I have dovecot 0.99.11 on a Linux machine running against a maildir based mailbox. I am getting the following errors in the maillog: Nov 27 23:08:14 fawad3 imap(fawad): file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) Nov 27 23:08:14 fawad3 dovecot: child 14202 (imap) killed with signal 6 This happens when the mail reader tries to enumerate the messages in the INBOX. I am able to read the messages whose headers have already been cached by the mail reader. It is also able to read others folders without any problem. This problem has occured before, and I was able to get rid of it by identifying the junk mail message it was dying on. In this case, however, I'm not able to figure out which message is causing it to crash. I am able to read the same maildir in mutt, and Courier IMAP doesn't seem to have trouble with it either. I'd really appreciate if someone could tell me what I can do to get around this problem. Regards -fawad

Dovecot is running on RHEL 3, on top of Redhat/Sistina GFS (clustered filesystem.) Currently I'm keeping it on one node to avoid possible GFS locking issues. I'm running with mmap_disabled=yes, mbox format. Most of the 1.0-test builds I have done eventually corrupt their index files, and show strange behavior (click on a message in the folder view, and an entirely different message opens... delete three or four messages and expunge, the messages instantly reappear as unseen.). I typically wipe the .imap directories between different builds of Dovecot. I've been following the -test code for a couple of months now, just to see how it does, because we're running UW IMAPd and are excited to have a way to increase the performance of our mail cluster (indexes) without having to move away from mbox. Let me know if there's more information I could provide that would be helpful. Jim

[Dovecot] Excessive imap_login processes
by Keith Edmunds 02 Dec '04

02 Dec '04

I'm running Dovecot on a very small mail server (never more than six users accessing IMAP, often fewer). I'm seeing the number of imap_login processes grow over time, and right now there are 23. All the "login_process_*" settings in dovecot.conf are commented (ie, at their defaults). Is this a known or expected issue? The version of Dovecot is 0.99.10.8, which I accept is perhaps a little old. Thanks, Keith

Hi, because the fedora project switcht from wu imap to dovecot, i followed this step. Today I'm very unhappy about this step, because there are more problems for me than advantages... But today the biggest problem is, that a lot!!! of mailboxes are damaged. within three year no mailbox was damaged using wu imap. The errormessage is: imap(cstrang): File isn't in mbox format: /var/mail/cstrang the server is fedora core 1, dovecot-0.99.11. May be I have something misconfigured, but where to look at? Any ideas, what causes the damage? And installing the test-version isnt an alternativ for my production server vor 500 users.

Hello. I am using dovecot-1.0-test53 with Maildir mailstore, with pine 4.61 as MUA. I have several folders which cause error messages like 'Junk in start of group' in Pine when I read them. I googled a bit for this, and found that removing the index file should do the trick, but unfortunately, it does not. What can I do to make these annoying messages disappear ? Thanks in advance. -- Nicolas
