[Dovecot] Dovecot dict process privileges
by Mike Mimic 30 Aug '10

30 Aug '10

Hi! Is it possible to configure Dovecot so that it drops privileges for dict process? Currently this process is running as root. (At least on my system with Dovecot 1.2.) Best regards Mike

Could you explain the iterate_query in any kind of sql. I'm guessing to just use the query, correctly, that's failing as iterate_query= and put it in the service auth file which includes password_query and user_query. then, I'm guessing to add something like: iteratedb { driver = sql args = /path/to/sql.conf } The wiki2 only says: "When the SQL userdb module is used make sure that the iterate_query setting in /etc/dovecot/dovecot-sql.conf.ext matches your database layout." it should give an example query. I don't know if its wanting to list the fields or the contents of a field. Thanks, Jerrale G Jerrale G. SC Senior Admin

[Dovecot] Can't get dovecot to see email folders
by Blaster 30 Aug '10

30 Aug '10

So I'm very frustrated, I've spent the better part of a day trying to get dovecot 2.0.1 working...Most of the documentation on the Wiki seems to think you are running an older version and therefore very little of it applies. I'm running 2.0.1 on OpenSolaris. I seem to have 2 remaining issues: 1) Dovecot is not able to determine the home directory 2) IMAP clients can not get to the mail folder directory. One client is reporting that it can't open it in read only mode. 3) I tried to get raw logging working, but apparently I couldn't because of #1. The architecture of Dovecot makes it difficult to transition from another IMAP server. If I force the MBOX to be /home/%u/mail, all of my clients think the folders are in /home/%u/mail/mail. If I set mbox location to /home/%u, then dovecot tries to create .subscription and .imap files/directories in the users home dir which it doesn't have permission to do. It would be nice if you could configure Dovecot in such a way as to make transition easier, such as the ability to strip off a duplicate trailing path, ie /home/%u/mail/mail becomes /home/%u/mail....Otherwise this necessitates visiting countless IMAP clients for reconfiguration... Here is my config file: /opt/sbin/dovecot -n # 2.0.1: /opt/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc base_dir = /var/run/dovecot/ mail_debug = yes mail_gid = mail mail_location = mbox:/home/%u/mail:INBOX=/var/mail/%u mail_privileged_group = mail mail_uid = dovecot passdb { driver = pam } plugin { home = /home/%u } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { address = * port = 993 } } service pop3-login { inet_listener pop3 { address = * port = 0 } inet_listener pop3s { address = * port = 0 } } ssl_cert = </usr/local/ssl/certs/dovecot.pem ssl_key = </usr/local/ssl/private/dovecot.pem gremlin [/opt/bin] # gremlin [/opt/bin] #

[Dovecot] PAM authentication fails
by Egbert Jan van den Bussche 29 Aug '10

29 Aug '10

Hi, I'm fighting all weekend on with auth and pam to authenticate local system users. testuser is such local user and is in passwd and shadow. I want to have local system users (testuser is one of them) and virtual users. The virtual part works fine but I cannot get the local user to connect. Still pam fails finding the user. The suggested password mismatch at the end is, in my eyes, because there is no user in the first place. I verified the password by interactive login to the account. The pam module (dovecot) is just the default file with three @includes in it.

[Dovecot] Sent mail issue
by Piyush Joshi 29 Aug '10

29 Aug '10

Dear All, I have few question regarding dovecot configuration for specific need which are as follows:- 1. I have IMAP folder with the name Sent Mail and i want whenever client uses any MUA to send mail from my server his mail must be kept in server's IMAP folder which is Sent Mail instead of local Sent folder. 2. Whenever user configures account in MUA, MUA automatically create some new folder like Junk Mail etc. while i am already using Spam folder to keep spam message in that folder so let me know how can i save myself from this. 3. Is there any thing which can also put deleted message in my server's Trash folder. Thanks

[Dovecot] "Multiple Commands in Progress" support
by Mike Cardwell 29 Aug '10

29 Aug '10

Section 5.5 of RFC3501 discusses the ability of IMAP servers to receive and execute multiple commands asynchronously on a single IMAP connection, not necessarily responding in the same order the commands were received: http://tools.ietf.org/html/rfc3501#section-5.5 Does Dovecot take advantage of this ability, or does it simply queue up the commands and execute them synchronously in order? -- Mike Cardwell - Perl/Java/Web developer, Linux admin, Email admin Read my tech Blog - https://secure.grepular.com/ Follow me on Twitter - http://twitter.com/mickeyc Hire me - http://cardwellit.com/ http://uk.linkedin.com/in/mikecardwell

[Dovecot] When should dictionary entries for the expire plugin be added/updated?
by Ralph Seichter 28 Aug '10

28 Aug '10

I've set up Dovecot 2.0 with the expire plugin using an SQLite DB, and when mail is delivered via dovecto-lda, the DB gets updated as expected. However, when I use Thunderbird 3.1.2 for Mac OS X to move a message to any of the folders known to the expire plugin (e.g. the 'tmp' folder), the SQLite DB is not updated. Here is an excerpt of my current configuration: # /etc/dovecot/dovecot.conf dict { expire = sqlite:/etc/dovecot/dict-expire.conf } plugin { expire = Junk expire2 = Trash expire3 = tmp expire4 = *.News expire5 = *.Reports expire_dict = proxy::expire sieve = /etc/dovecot/sieve/%u.sieve } service dict { unix_listener dict { # Ensure that there is no permission-related problem mode = 0666 } } protocol lda { mail_plugins = expire sieve postmaster_address = postmaster(a)domain.tld sendmail_path = /usr/sbin/sendmail } # /etc/dovecot/dict-expire.conf connect = /var/lib/dovecot/expires.sqlite map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire fields { username = $user mailbox = $mailbox } } # Schema dump of /var/lib/dovecot/expires.sqlite PRAGMA foreign_keys=OFF; BEGIN TRANSACTION; CREATE TABLE expires ( username VARCHAR(75) NOT NULL, mailbox VARCHAR(255) NOT NULL, expire integer NOT NULL, PRIMARY KEY (username, mailbox) ); CREATE TRIGGER mergeexpire BEFORE INSERT ON expires FOR EACH ROW BEGIN UPDATE expires SET expire=NEW.expire WHERE username=NEW.username AND mailbox=NEW.mailbox; SELECT RAISE(IGNORE) WHERE (SELECT 1 FROM expires WHERE username=NEW.username AND mailbox=NEW.mailbox) IS NOT NULL; END; COMMIT; With these settings, rows will be inserted to (or updated within) expires.sqlite when dovecot-lda stores messages to any of my "Reports" folders using sieve rules. When I manually move messages to "tmp" or "Junk", the database remains unchanged. Also, when I delete messages in Thunderbird, I'd expect database additions for the folder "Trash", but this does not happen either. What am I doing wrong here? -Ralph
