[Dovecot] Outlook express confusion
by Andrew Hutchings 08 Apr '05

08 Apr '05

Hi, This may be a problem with my config file but I am finding that customers (and more importantly my boss) that are using outlook express when using test66/67 (upgraded from test60 + from address patch) are having message reappear after being fully deleted (not just marked) but are unreadable, sometimes blank headers appear too but again no message. Since it is affecting my boss he has told me to go back to test60 or lower, and won't let me find the problem.

[Dovecot] maildir quota management
by Wayne Lovely 08 Apr '05

08 Apr '05

Hi everyone, my name is Wayne Lovely and this is my first post. My company has a need for dovecot to decrement the portion of quota used. The used portion and hard limit will be stored in a central database. Initially I'll just hack in what we need as a proof of concept, but I would like to get some input into what people would really like, such that I can make a good contribution. regards, Wayne Lovely

[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...
by Lawrence Katz 08 Apr '05

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

[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
