[Dovecot] v1.1.1: Some files not created with dovecot-shared permissions
by Eduardo M KALINOWSKI 21 Jul '08

21 Jul '08

Hi, I use dovecot-shared to add read permissions to the group in my mail server, which uses virtual users. This is only to ease backups. However, a few files are not created with the permissions in dovecot-shared. I've seen this happen to 'subscriptions', 'maildirfolder' (when dovecot-shared exists; the change to correctly create maildirfolder in this case is very recent), and possibly 'maildirsize' (I'm not sure about this one, it might be exim that is creating it with wrong permissions.) This has been tested in recent snapshot package, from the Debian repository listed at http://wiki.dovecot.org/PrebuiltBinaries. Here's dovecot -n for reference: # 1.1.1: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: username_format=%n /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir

Hello, We recently upgraded to Dovecot 1.1 from 1.0.5 and we are having few issues: 1) Maildir's are not created anymore for new users if they dont excits, the directories where created before, is this a configuration issue? 2) Cannot subscribe to shared folders, if currently subscribed they work fine but cannot re-subscribe, also i noticed that the control directory for the namespace is not created anymore, before it was, any ideas? //sami conf: 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: ready. login_processes_count: 5 verbose_proctitle: yes first_valid_uid: 1000 mail_location: maildir:~/:INDEX=/var/dovecot/index/%u:CONTROL=/var/dovecot/control/%u mail_nfs_storage: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_process_size: 1024 mail_plugins(default): acl quota imap_quota mail_plugins(imap): acl quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle, delay-newmail imap_client_workarounds(imap): outlook-idle, delay-newmail imap_client_workarounds(pop3): namespace: type: private separator: / location: maildir:~/:INDEX=/var/dovecot/index/%u:CONTROL=/var/dovecot/control/%u inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/var/mail/jaetut:INDEX=/var/dovecot/jaetut/index/%u:CONTROL=/var/dovecot/jaetut/control/%u list: yes subscriptions: yes auth default: passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: prefetch plugin: quota: fs acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] AIX: mntctl implementation for NFS quota support
by Ralf Becker 20 Jul '08

20 Jul '08

Hi Timo, Hello list, I've played around with dovecot-1.1.1 on AIX to get quotas (especially NFS quotas) to work. I've found that dovecot doesn't implement handling of 'mntctl' and so it is unable to determine filesystem mountpoints on AIX correctly. Your'll find more information about 'mntctl' here: http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.a… Okay... I've added mntctl support to 'lib/mountpoint.c' today. My tests are looking good and so I'd like to share the patch. While I'm still not really familiar with dovecots memory management, I need someone who is familiar with it to have a look on my lines of code. Especially the usage or p_new, t_strconcat and p_free should be checked. :-) To activate the patch you have to add "#define HAVE_VMOUNT_H 1" do 'config.h'. Maybe someone wants to alter configure* to do this automatically? And of course Timo, if you find it useful, you may include the code in one of the next dovecot releases.

[Dovecot] Moving from pysieved to native ManageSieve?

If moving from pysieved to Dovecot native ManageSieve implementation, should this just work or do I need to do anything with existing sieve filter rule files, etc? Any reasons not to do the switch?

[Dovecot] v1.1.rc13 released
by Timo Sirainen 20 Jul '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc13.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc13.tar.gz.sig There's always time for one more release candidate. :) I was planning on releasing v1.1.0 a couple of minutes before summer solstice (23:59 UTC according to Wikipedia). Maybe it'll bring luck to the release. :) - mbox: Fixed a crash when adding a new X-IMAPbase: header with keywords. - Message parser: Fixed assert-crash if cached MIME structure was broken. - Squat: Potential crashfix with mmap_disable=yes.

OK I've been struggling to get dumps from the live environment most of the day, but have given up. I've now managed to reproduce this using a fork-bomb type script; here is a backtrace (no debug version installed, but I suspect I could reproduce this in the dev environment if it's not clear what the error is).

A word about our setup; we have the maildirs stored on an nfs mount and deliver could be called on multiple heads at the same time for deliveries - I suspect this is what was causing the problem. Our nfs mount options are rw,noatime,nodiratime,hard,intr,rsize=32768,wsize=32768,tcp,nocto. Running centos 5.1 on the boxes with exim. Thanks, Mark
