[Dovecot] Problem with mail_location and INDEX location
by Matt Jones 29 Nov '12

29 Nov '12

HI, I'm pulling my hair out a little trying to get dovecot to save it's index locally rather than in the NFS mount. No matter what I do it seems to save the indices in the Maildir on the NFS. I'm using dovecot 2.0.18 on CentOS 6.3. The relevant config I'm using: mmap_disable = no dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster mail_fsync = always mail_nfs_storage = yes mail_nfs_index = no lock_method = dotlock # Mail location and mailbox format. mail_location = maildir:/%Lh/Maildir/:INDEX=/var/indexes/%Ld/%Lu/ Dovecot runs under the user:group vmail:vmail, and the user has write access to those directories. [root@tay var]# ls -al total 96 drwxr-xr-x. 24 root root 4096 Nov 29 09:36 . dr-xr-xr-x. 23 root root 4096 Nov 28 15:26 .. drwxr-x--- 5 amavis amavis 4096 Nov 29 09:21 amavis drwxr-xr-x. 10 root root 4096 Nov 28 15:14 cache drwxr-xr-x. 2 clamav clamav 4096 Nov 29 03:49 clamav drwxr-xr-x. 3 root root 4096 Nov 28 14:21 db drwxr-xr-x. 3 root root 4096 Nov 28 13:35 empty drwxr-xr-x. 2 root root 4096 Sep 23 2011 games drwx------ 2 vmail vmail 4096 Nov 29 10:42 indexes drwxr-xr-x. 25 root root 4096 Nov 28 15:15 lib drwxr-xr-x. 2 root root 4096 Sep 23 2011 local drwxrwxr-x. 5 root lock 4096 Nov 29 03:49 lock drwxr-xr-x. 5 root root 4096 Nov 29 04:10 log lrwxrwxrwx. 1 root root 10 Nov 28 13:34 mail -> spool/mail drwxr-xr-x. 2 root root 4096 Sep 23 2011 nis drwxr-xr-x. 2 root root 4096 Sep 23 2011 opt drwxr-xr-x. 2 root root 4096 Sep 23 2011 preserve drwxr-xr-x. 20 root root 4096 Nov 29 09:51 run drwxr-xr-x. 9 root root 4096 Nov 28 15:14 spool drwxrwxrwt. 3 root root 4096 Nov 29 09:22 tmp drwxr-x--- 2 amavis amavis 4096 Jun 8 15:39 virusmails drwx------. 5 vmail vmail 4096 Nov 29 09:35 vmail drwx------. 3 root bin 4096 Nov 29 09:22 webmin drwxr-xr-x. 12 root root 4096 Nov 28 15:17 www drwxr-xr-x. 2 root root 4096 Sep 23 2011 yp After restarting dovecot, and logging in via imap, I see the following under the Maildir: [root@tay Maildir]# ls -al /var/vmail/vmail1/orphans.co.uk/m/a/t/matt-2011.07.06.09.41.05/Maildir total 56 drwx------ 9 vmail vmail 4096 Nov 29 10:57 . drwx------ 3 vmail vmail 4096 Nov 29 10:17 .. drwx------ 2 vmail vmail 4096 Nov 29 10:41 cur -rw------- 1 vmail vmail 248 Nov 29 10:41 dovecot.index.log -rw------- 1 vmail vmail 120 Nov 29 10:41 dovecot.mailbox.log -rw------- 1 vmail vmail 51 Nov 29 10:41 dovecot-uidlist -rw------- 1 vmail vmail 8 Nov 29 10:41 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 Nov 29 10:41 dovecot-uidvalidity.50b73be3 drwx------ 5 vmail vmail 4096 Nov 29 10:41 .Drafts drwx------ 5 vmail vmail 4096 Nov 29 10:41 .Junk drwx------ 2 vmail vmail 4096 Nov 29 10:41 new drwx------ 5 vmail vmail 4096 Nov 29 10:41 .Sent -rw------- 1 vmail vmail 29 Nov 29 10:41 subscriptions drwx------ 2 vmail vmail 4096 Nov 29 10:41 tmp drwx------ 5 vmail vmail 4096 Nov 29 10:41 .Trash [root@tay Maildir]# ls -al /var/indexes/ total 8 drwx------ 2 vmail vmail 4096 Nov 29 10:42 . drwxr-xr-x. 24 root root 4096 Nov 29 09:36 ..

[Dovecot] Shutting down my Dovecot server?
by Bjørn T Johansen 29 Nov '12

29 Nov '12

I am planning to shut down my own Dovecot server and start using the other Dovecot server I am administering together with a friend.. And I was thinking that I don't want to copy the emails I have on my server so I want to start from scratch on the other server.. But I would like to be able to look at the old emails if I need to, so was wondering if there is a way to do this without using an imap server? Can I convert my mails stored in the maildir format to mbox or is there a better way to solve my problem?

Hi, I know it's a while since you've had this issue, but still do you remember by any chance how you solved this? I'm having the same problems, when all the directories are created with 700 and I need a group permissions to be at least 750. Thanks! regards,

[Dovecot] shared mailboxes and indexes
by Angel L. Mateo 28 Nov '12

28 Nov '12

Hello, We are deploying shared mailboxes in our mail system. We are running 2.1.9 and mail backend is maildir. As described at http://wiki.dovecot.org/SharedMailboxes/Shared when shared namespace is configured as namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } each user accessing this folder has its own index, stored in ~/Maildir/shared/%%u/<shared mailbox>, hasn't it? Our mail is store in NFS disks so we are very concerned about indexes optimizations (we had performance problems until we got all of our indexes and nfs tunned). So, is there any way so those indexes could be shared for all users (and they always would be updated). Regarding this... if we'd use dbox instead of maildir, indexes are a really important part of the mailbox and they can't be re-constructed when they are outdated. So, how do shared mailboxes work with dbox backend? Do I have to configure indexes in any particular way? -- Angel L.

[Dovecot] problems with quota and clients
by Marco Sacchetto 28 Nov '12

28 Nov '12

Hi, I had configured dovecot in a pretty standard way and had it working nicely enough with maildir quotas (no tests done apart for reaching the quota and looking at mails coming back). Still I wanted to have the quota and the actual quota usage displayed in postfixadmin (3.5) but I think I messed with something. Now I can connect to the mailbox, send mail, receive mail, see the quota usage in postfixadmin but: * thunderbird: can create a subfolder if i do so by hand from the client. But if I try sending a mail i get a [TRYCREATE] mailbox error as it seems that thunderbird can't create the Sent box anymore by its own; * thunderbird: when i delete mail, it goes in the trash folder. I try then to delete it from there. In thunderbird indeed I see no mail anymore but the quota level remain the same. Then I try to browser the mail directory and... yep, all the messages are still there! How come? This is the output of dovecot -n and the relevant sql configuration : # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-33-generic i686 Ubuntu 12.04.1 LTS ext4 auth_mechanisms = plain login auth_realms = yyyyyyyyy.it aaaaaaa.com xxxxx.it auth_verbose_passwords = plain debug_log_path = syslog dict { quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_uid = 150 info_log_path = /var/log/syslog last_valid_uid = 150 listen = * mail_debug = yes mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = " quota" mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=50M quota_rule2 = Trash:storage=+10M } postmaster_address = xxxxxxxx(a)yyyyyyyyy.it protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0660 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } >>grep -v '^ *$#.*$\?$' dovecot-dict-sql.conf.ext connect = host=127.0.0.1 dbname=mail user=mail password=xxxxxxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } >>grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=localhost dbname=mail user=mail password=xxxxxxx default_pass_scheme = MD5-CRYPT password_query = \ SELECT username as user, password, '/var/vmail/%d/%u' as userdb_home, \ 'maildir:/var/vmail/%d/%u' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid \ FROM mailbox WHERE username = '%u' AND active = '1' user_query = \ SELECT '/var/vmail/%d/%u' as home, 'maildir:/var/vmail/%d/%u' as mail, \ 150 AS uid, 8 AS gid, CONCAT('*:storage=',ROUND(mailbox.quota / 1024)) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = '1' iterate_query = SELECT username AS user FROM mailbox -- -- Questo messaggio è di carattere riservato ed è indirizzato esclusivamente al destinatario specificato.

[Dovecot] Any chance to access read-only mdboxes?
by Jost Krieger 28 Nov '12

28 Nov '12

We would like to provide a self-service restore function to our users using their IMAP client of choice.. Our idea was to use a snapshot (under ZFS, btrfs, whatever) and have it available to the user in a namespace. Unfortunately, but understandably, dovecot doesn't like the mdbox structure to be read-only. Is there any chance to change that? In the meantime, we could use a read-write snapshot, but we wouldn't like the users to really do changes to that snapshot. Our next attempt is to use ACLs, but it's a bit hard to gt the ACLs to the correct place in the snapshots, at least for thousands of users. Our currents solution (in test) is a quick and dirty patch to introduce inheritance to the ACLs by walking up the directory tree, so we need only one ACL. A cleaner solution would be very much appreciated. Yours Jost Krieger -- | Helft Spam ausrotten!
