[Dovecot] Multiple quota roots with quota-fs backend
by Ralf Becker 21 Jul '08

21 Jul '08

Today I've tried to configure multiple filesystem quotas, with some strange results. These are my two filesystems; both using quotas: * /dev/mail mounted to /var/spool/mail using AIX quotas for all users. Mailbox format is 'mbox' and they are named '/var/spool/mail/<logname>' * filer0:/vol/home mounted to /home/f0 via nfs using netapp quotas for all users. Mailboxes are all 'mbox' and located in '~<logname>/Mail' I've configured _two_ quota roots as described here: http://wiki.dovecot.org/Quota/FS?highlight=(two%20filesystems) plugin { quota = fs:Home:mount=/home/f0 quota2 = fs:Spool:mount=/var/spool/mail } This works like a charm, but when testing the configuration, the result was just surprising: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. You see, that _always_ both quota roots are reported, whether the references mailbox is actually placed on this filesystem or not. However reading RFC2087 confirms me in the idea, that just the _related_ quota roots should be listed: -------------------------------8<----------------------------------------- 4.3. GETQUOTAROOT Command Arguments: mailbox name Data: untagged responses: QUOTAROOT, QUOTA Result: OK - getquota completed NO - getquota error: no such mailbox, permission denied BAD - command unknown or arguments invalid The GETQUOTAROOT command takes the name of a mailbox and returns the list of quota roots for the mailbox in an untagged QUOTAROOT response. For each listed quota root, it also returns the quota root's resource usage and limits in an untagged QUOTA response. Example: C: A003 GETQUOTAROOT INBOX S: * QUOTAROOT INBOX "" S: * QUOTA "" (STORAGE 10 512) S: A003 OK Getquota completed ------------------------------->8----------------------------------------- So in my opinion correctly reported quota roots should look like this: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Spool" * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" * QUOTA "Home" (STORAGE 310360 1048576) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. Now I known what I want... but how to get it :-) While I see no way to use namespaces and/or quota rules to configure this behavior, patching quota.c, quota-fs.c and quota-private.h seems to be an option. A downside of this is, that I've to extend the quota plugin interface (quota_backend_vfuncs) defined in quota-private.h by adding an new callback function. Since all other quota backends don't have this new function, they have to initialize it with NULL. So there are side effects to other quota backends. This is the reason why I want to discuss the above described problem (and solution) before posting my patch :-) Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[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

[Dovecot] AIX: mntctl implementation for NFS quota support
by Ralf Becker 21 Jul '08

21 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.

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

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.
