[Dovecot] 1.0-test67
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ Hopefully better release than last one. Fixes several problems test66 had and also some older problems reported in this list. It also contains a pretty large mbox code cleanup, fixing several problems (especially related to X-IMAP/X-IMAPbase headers) and making it a bit faster. Maybe I'll backport it to 1.0-stable too when it looks like it's stable.. BTW. mbox code is slower than necessary when updating message flags and mbox_lazy_writes=yes, because it reads message headers for each message whose flag is to be changed (in index). Should fix that one soon too..

Re: [Dovecot] Delimiter of mailbox changes in response to STATUS command...

Hi Chris - Thank you for the reply. > I can't reproduce this in our setup in either 1.0-stable or > 1.0-test66. What's your namespace definition and MAIL= environment? > What does > > 1 LIST "Misc/" "*" > > give you? The LIST command returns what I expect to see (for readability): 2 list "Misc/" "*" * LIST (\HasNoChildren) "/" "Misc/Spam" > Can you 1 SELECT "Misc/Spam" OK? I can select that mailbox as well as others without a problem. Here's what NAMESPACE returns: 3 NAMESPACE * NAMESPACE (("" "/")) NIL NIL My namespace definition in dovecot.conf is as follows: namespace private { separator = / # prefix = # location = inbox = yes # hidden = yes } I didn't have default_mail_env set to anything, but I just tried the following without a change in the STATUS command's behavior: default_mail_env = maildir:/home/%u/Maildir Is there any other information that might help? Thanks, Lawrence

[Dovecot] Linux, Maildir over NFS, Locking problems
by Terrence Martin 08 Apr '05

08 Apr '05

Hi, I am having problems with file locks with my NFS mounted Maildir setup. NFS Client/IMAP Server is RHEL3 clone whitebox and NFS server is a Fedora Core 2 system. Both are running lockd as far as I can tell. dovecot is installed with Dag's latest dovecot RPMs for RHEL3. Time is synced between the two systems. Here is the pertinent log file entry dovecot: Dovecot starting up Apr 7 11:17:42 sentry imap(tmartin): /home/tmartin/Maildir/.subscriptions failed with subscription file file_wait_lock(): No locks available Now what I can find in nfs.txt is that I need to use fnctl is this ".customflags and .subscriptions files require fcntl() locking currently. Many NFS servers don't support it, at least without a separate lockd daemon. These will be fixed later to be NFS-safe by default." My question is am I using fcntl? The only reference I can find in the config refers to mbox formats, but I am using maildir. Setting the one reference to fcntl does not seem to have any effect. Is there a configuration setting to tell the server to use fcntl locks or a way to tell if it is trying to use fcntl locks? Thanks for any tips, Terrence

[Dovecot] MySQL-Auth Problem
by Felix Jirka 08 Apr '05

08 Apr '05

Hi, i would use Dovecot-test66 with MySQL-Auth for virtual users. MySQLd version: 4.1.10a I compliled dovecot with: CPPFLAGS=-I/usr/include/mysql LDFLAGS=-L/usr/lib ./configure --prefix=/usr --sysconfdir=/etc/dovecot --without-passwd --without-shadow --without-pam --without-checkpassword --without-bsdauth --without-vpopmail --with-mysql --with-ssl=openssl --with-storages=maildir --with-moduledir=/etc/dovecot/modules but if i start Dovecot i get: Apr 3 12:44:28 l2 dovecot: auth-worker(default): mysql: Connect failed to 127.0.0.1 (mail): Benutzer 'mail'@'localhost' hat keine Zugriffsberechtigung (verwendetes Passwort: Ja) - waiting for 75 seconds before retry but password and user are correct and worked with dovecot 0.99.14 cu Felix

[Dovecot] 1.0-test66
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ I've still lots of mails in my INBOX and in this list that I should be looking into.. But here's a release that fixes at least some things. Maybe I'll make another one tomorrow.. Most importantly keyword code was changed a lot. It's now faster and less buggy. The keywords are also finally written into mbox, and keyword changes in the mbox are picked up. So upgrading from Dovecot 0.99.x or UW-IMAP (or reverting back to them) doesn't anymore lose the keywords. Maildir still needs 0.99.x-compatible customflags-file and storing the keywords as a..z flags in maildir filename. Hopefully I'll get that done soon, and then we should be nearing 1.0-alpha1 release :) The new keyword code hasn't been tested much, so this might be less stable than earlier versions. - Renamed oe6-fetch-no-newmail workaround to delay-newmail and changed it to work more like the name says: only newmail notifications are skipped and not only for FETCH command. - LDAP crashfixes - Changed FETCH to return smaller items first. Should fix all kmail and Thunderbird problems. Removed tb-negative-fetch workaround as it shouldn't be needed anymore. - Cache file was breaking constantly with test65 - Blocking passdb fixes and proper RPA realm support patches from Andrey - in-memory indexes should be working again if someone wants to use them for some reason (:INDEX=MEMORY) - gzipped mbox plugin http://dovecot.org/patches/1.0/zlib-plugin.tar.gz - SORT crashfix - Some mbox rewriting fixes (should fix some asserts) - etc.

[Dovecot] imap segfault in mail-cache.c
by Todd Burroughs 08 Apr '05

08 Apr '05

Found an imap crash. I'm using the CVS copy from March 23. This is running under Linux, kernel 2.6.11.something. We use mbox over NFS, everything is on the NFS server. There is currently only one dovecot server accessing the mailbox.

[Dovecot] Archiving Dovecot format maildir
by Leslie Viljoen 08 Apr '05

08 Apr '05

Hi! It seems that the Maildir format used by Dovecot is a standard, right? Has anyone written something to archive mail in Dovecot format maildirs? I have a script that seems to be for Cyrus IMAP but it doesn't seem to work. I'll write a Perl program if there is nothing available but I am concerned about dovecot's index files - do I need to do anything to get dovecot to rebuild them? Leslie Viljoen

[Dovecot] headers don't match message
by Kevin 08 Apr '05

08 Apr '05

the other day i moved all mail functions to a different machine. i copied over my existing maildir's and installed dovecot-stable-20050405. once i had everything moved and dovecot running i checked my mail via imap. all the messages appeared however when i try to read a message the message body doesn't match the header info that's showed in the message list. is this an index problem? or did i corrupt my maildir when i moved it over to another host?

[Dovecot] public or shared folders
by Richard Stegman 08 Apr '05

08 Apr '05

Hello I would like to setup a public namespace with folders under it that are accessiable by certain users. Something like this: Projects---- | |-----03060 | |-----04579 Users should be able to move emails from their inbox to the shared folders, and all user can see the moved email. Here is what I have done so far: 1. I installed dovecot-1.0-0 4 stable20050221.rhf3.at.i386.rpm to a Fedora core 3 machine with Postfix and procmail. 2. Tested mail server - both pop and imap work. 3. Modified dovecot conf. file with the following entry: namespace private { separator = / prefix = inbox = yes hidden = no } namespace public { separator = . prefix = Projects. location = maildir:/var/mail/Projects inbox = no hidden = no } 4. Restart dovecot. Test - imap and pop work. 5. Create group imapu. Add email users to group imapu 6. Create (as root) /var/mail/Projects. Change group to imapu. Change mode 770 7. Touch file dovecot-shared to /var/mail/Projects. Change group to imapu. Change mode 770 8. Make directory /var/mail/Projects/.03060. Change group to imapu. Change mode 770 9. Touch file dovecot-shared to /var/mail/Projects/.03060. Change group to imapu. Change mode to 770 10. Restart dovecot. I start up thunderbird and the Project namespace shows up. I then subscribe to 03060 and get this error: The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' <10240.-1357>'. I click ok and I can move email from the inbox to 03060. The mail shows up in 03060. No other user can then subscribe to 03060. What am I doing wrong? Thanks Rick
