[Dovecot] quota sql dict permissions dilemma
by LEVAI Daniel 18 Oct '10

18 Oct '10

Hi! I'm trying to set up SQL based dict quota. The quota is working, gets updated but I had to configure really loose file permission to make it work: dovecot.conf: dict { quota = pgsql:/etc/dovecot/dovecot_dict-sql.conf } service dict { unix_listener dict { mode = 0660 group = vmail # sidenote: I noticed that writing the number equivalent # of 'vmail' here does not work. Why? } } # ~ls -la /etc/dovecot/dovecot_dict-sql.conf -rw-r----- root vmail dovecot_dict-sql.conf # ~ls -la /var/dovecot/dict srw-rw---- root vmail /var/dovecot/dict= Every virtual user lookup returns a 'gid' field, and it is always 'vmail' (actually it is the number equivalent of 'vmail'). Despite that the imap process should run as the 'uid' and 'gid' values returned from the userdb, it can not read the dict config file: dovecot.log: dict: Error: Can't open configuration file /etc/dovecot/dovecot_dict-sql.conf: Permission denied dict: Error: Failed to initialize dictionary 'quota' lda(<username>): Error: read(/var/dovecot//dict) failed: Remote disconnected Now I must set o+r to the config file, which I really don't want to, given that it contains the db username and password. Strange thing is that the group r/w permission is enough for the dict= socket, and it doesn't need world-wide permissions at all.

[Dovecot] kmail-error: can't upload folder (imap-account on dovecot-server)
by cool.chris65＠web.de 17 Oct '10

17 Oct '10

Hello, I've some trouble with my kmail (Version 1.13.5 / KDE 4.5.1, Kubuntu 10.04 and a dovecot-imap-server on debian etch (dovecot 1.0.rc15-2etch5). Everytime I try to create a folder under my imap-inbox, I get an error like "can't upload folder...", but after this message I can see a new folder under my inbox-folder, but I can't use it ... With a thundermail-client I can create a subfolder without any erro and I can use it r (but only first level). My conf: # /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot.log disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Herzlich Willkommen, %u. mail_location: mbox:~/mail imap_client_workarounds: outlook-idle tb-extra-mailbox-sep auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd The reason for using debian etch and dovecot 1.0 is the hardware: it's running on a Fritzbox-Router, and there is actual a littlebit trouble with lenny (often crashing, reboots of the whole box etc.) I hope, someone can help me ...

[Dovecot] Quota, Postgres + Postfixadmin
by Roman 17 Oct '10

17 Oct '10

Hi everybody, i am currently testing dovecot-1.2.9 together with postfix, postgres and postfixadmin. After setting up the basics, i wanted to get the quotas working... So i edited the dovecot.conf: mail_plugins = quota imap_quota mail_plugins = sieve quota quotadict = pgsql:/etc/dovecot/dovecot-dict-quota.conf quota = dict:user::proxy::quotadict and dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=yyy password=xxx 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 } After moving some mail on and off the account and finally cleaning out any mail (verified via console) quota2 looks like this: username bytes messages test(a)testdomain.de -1009339 -1 So it seems to me its calculating sth. wrong? Or am i doing sth. wrong? greetings, Roman -- printk(KERN_ERR "happy meal: Transceiver and a coke please."); linux-2.6.6/drivers/net/sunhme.c

[Dovecot] Convert plugin
by Egbert Jan van den Bussche 15 Oct '10

15 Oct '10

Hi, I'm trying to get old mail from /var/mail/<user>, where <user> is the (sometimes) huge mailfile, not a directory, converted to the maildir INBOX in ~/Maildir. Users have no ~/mail directory; they were supposed to use pop3 only. I'm trying the example from the wiki: plugin { convert_mail = mbox:~/mail:INBOX=/var/mail/%n } but have still not succeded. I tried /var/mail/<user> where <user> is a file and /var/mail/<user>/<user> where user is first a diredtory en the second <user> a file. I also used the filename 'inbox', since the logging suggested that to me. Other logging seems to indicate that the right maildir++ info is composed. I'm in vor any advise!

[Dovecot] Weird glitches with public folders - Dovecot not using per-user INDEX?
by Kádár Tamás (KTamas) 15 Oct '10

15 Oct '10

Hi I have this public folder: namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } Access is controlled by ACLs, everyone who has access is 'lrwstipek' except for some people who also have 'xa' privileges. As you can see it is set to put its index to the user's Maildir so they can have per-user \Seen flags. And that is the case -- most of the time anyway. But for some folders, and I can't figure out why those, they just don't work: if someone sets a message read it immediately becomes read for everyone else, too, and vice versa if someone marks a message unread, it becomes unread everywhere. Further investigation shows that in these problematic folders, indeed all users directly manipulate the flag of the email (i.e. X marks email Z read, ",S" appears immediatelly in the filename). Anyone knows what I'm doing wrong? I can't seem to find anything different with these problematic folders, ACLs look right etc. Thanks in advance, Tamas

[Dovecot] Custom Flags
by qmail＠top-consulting.net 15 Oct '10

15 Oct '10

I have modified my delivery agent to deposit files in my Maildir already containing custom flags. For example, x is appended for files that are sent from local users, y is for e-mails from Contacts and z is for e-mails from Whitelisted sources. A file will thus be delivered in the Maildir and be called something like: filename:2,yz Also in the Maildir I created a file called dovecot-keywords and have added these 3 flags in there as so: #cat dovecot-keywords 23 Local 24 InContacts 25 Whitelisted I went ahead and erased all the dovecot-uid* dovecot.index* files but Dovecot won't recognize the flags - furthermore, it labels z as 'unknown-25'! - for both old messages or new messages. Here is a bit of IMAP conversation: a02 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted ) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted \*)] Flags permitted. a03 SEARCH KEYWORD Whitelisted * SEARCH * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted \*)] Flags permitted. a03 OK Search completed (0.004 secs). a04 SEARCH KEYWORD unknown-25 * SEARCH a04 OK Search completed (0.004 secs). I know for sure there are files with the z letter in their name in the Inbox. What is going wrong ?
