[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

I haven't been able to find any specific documentation for it, but I have found that the firewall works fine with postfix and several file services I use (enabling/disabling works as expected, process names get logged as expected, etc).

[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

There is a roff typo in pigeonhole's sievec.1.in. Roff treats the leading apostrophe on line 54 as an invalid command and produces bad output: dump to be written to stdout.

A tarball created from current pigeonhole hg using "make dist" doesn't include the files doc/man/{reporting-bugs.inc,sed.sh} and fails to build as a result. Attached patch works for me. Paul

[Dovecot] dovecot - mac firewall problem
by Patrick Fay 27 Aug '10

27 Aug '10

Hi, I am running dovecot 1.2.11 on mac osx 1.5.8. Everything works perfectly with the application-level firewall off, but enabling the application firewall prevents dovecot connections. I have tried explicitly authorizing dovecot in the firewall, but it does not work. I have searched everywhere I can think of to look, and haven't found a solution, but have seen a couple other reports of what seems to be the same problem. The firewall logs the activity with what looks like a corrupt process name: a typical appfirewall.log entry looks like: Aug 26 20:43:45 hostname Firewall[55]: Deny ^L connecting from XX.XX.XX.XX:37310 uid = 0 proto=6 Aug 26 20:43:53 hostname Firewall[55]: Deny ^H�^U��^Z connecting from XX.XX.XX.XX:37310 uid = 0 proto=6 Aug 26 20:44:09 hostname Firewall[55]: Deny ^L connecting from XX.XX.XX.XX:37310 uid = 0 proto=6 Aug 26 20:44:34 hostname Firewall[55]: Deny ^L connecting from XX.XX.XX.XX:37312 uid = 0 proto=6 Aug 26 20:44:45: --- last message repeated 6 times --- where "hostname" is my server name and the XX's are my client's IP address. For all of the other services I've used, the process name (e.g. dovecot) should appear after "Deny" when blocking traffic, instead of the funny characters. Any advice on how I could resolve this issue would be greatly appreciated. Thanks!

[Dovecot] LDAP & static userdb
by spamvoll＠googlemail.com 27 Aug '10

27 Aug '10

hi.. im just testing 2.0 before upgrading to v1.2 :) in auth-ldap.conf.ext i found # If you don't have any user-specific settings, you can avoid the userdb LDAP # lookup by using userdb static instead of userdb ldap, for example: # <doc/wiki/UserDatabase.Static.txt> #userdb { #driver = static #args = uid=vmail gid=vmail home=/var/vmail/%u #} On 1.2 im using LDAP lookup and everthing works like a charm. user_attrs = homeDirectory=home,uid=mail=maildir:/home/MAILBOXES/%$/mail On 2.0 is now tried to use this option cause all my mail are stored in /home/MAILBOXES/%uid/mail userdb { driver = static args = uid=vmail gid=vmail home=/home/MAILBOXES/%u/mail } and that doesnt work log say: dovecot: imap(hpeter): Error: user hpeter: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/home/MAILBOXES/hpeter/mail Hans
