[Dovecot] acl flag to limit imap_acl based acl changes
by Amon Ott 26 Jan '10

26 Jan '10

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still change all acl flags for all users with imap. Write accesses to mails are forbidden as they should. Is this intended or a bug? We would like to give all users the ability to use ACLs through IMAP, but the current behaviour endangers our read-only mail archives.

[Dovecot] dovecot 1.2.9 crash on subscribe with shared namespace
by Alessandro Bono 26 Jan '10

26 Jan '10

Hi all I'm testing dovecot to migrate from a cyrus 2.2 With TB2 if I use "subscribe" dovecot crash but only if I enable a shared namespace. Without explicit namespace or only with private namespace "subscribe" works Is this a problem already fixed in 1.2.10? is it a problem of my configuration? I tried different value for location in shared namespace but without any difference Below some info + gdb backtrace + dovecot -n Thanks Dovecot is version 1:1.2.9-1ubuntu2 from ubuntu lucid recompiled for ubuntu hardy on a xen domu amd64, fs is xfs warning: Can't read pathname for load map: Input/output error.

[Dovecot] Released Pigeonhole Sieve v0.1.15 and ManageSieve v0.11.11 for Dovecot v1.2.10
by Stephan Bosch 25 Jan '10

25 Jan '10

Hello Dovecot users, It's been a while since the last Pigeonhole Sieve and ManageSieve releases. That is why this release includes quite a few changes. Most interestingly, the include extension is updated to match the most recent specification, the Sieve interpreter now includes plugin support and ManageSieve now has support for enforcing quota on the size of scripts, the number of scripts and the space the scripts occupy on disk. Other than that, quite a few small bugs were fixed. One of which was in the i;ascii-numeric comparator. If one of the matched strings did not start with a digit, the comparator would always yield a 'less-than' result. In stead it should have considered the string starting with the non-digit character as having a positive infinite value. Elsewhere in this list, Julian Cowley pointed out that negative values also start with a non-digit character, which some people may not have understood (i.e. i;ascii-numeric works only on unsigned values). The bug fix in this release could therefore change result of certain misconceived (and probably spam-related) Sieve rules, so watch out! I started work on the spamtest(plus) and virustest extensions. These are implemented for the most part, but their configurability needs quite a bit more work. Changelog Sieve v0.1.15: * Enotify extension: - Adjusted notify method API for addition of new notification methods. - Set default importance level to 'normal' (was 'high'). * Include extension: updated implementation towards most recent specification (all should be backwards compatible): - Implemented global variables namespace. - Global command may now appear anywhere in a script. - Implemented script name checking using the requirements specified in the ManageSieve draft. - One issue remains: ManageSieve currently requires included scripts to be uploaded first, which is not according to specification. * Changed envelope path parser to allow to and from envelope addresses that have no domain part. + Added preliminary support for Sieve plugins and added support for installing Sieve development headers. + Started work on the implementation of the spamtest, spamtestplus and virustest extensions (unfinished). + Deprecated notify extension: implemented denotify command. + Variables extension: added support for variable namespaces. + Added configurable script size limit. Compiler will refuse to compile files larger than sieve_max_script_size. + Testsuite changes: - Added support for changing and testing an extension's configuration. - Added a command line parameter for copying errors to stderr. - Fixed a bug in the i;ascii-numeric comparator. If one of the strings started with a non-digit character, the comparator would always yield less-than. - Imap4flags extension: fixed bug in removeflag: removing a single flag failed due to off-by-one error (bug report by Julian Cowley). - Improved EACCES error messages for stat() and lstat() syscalls and slightly improved error messages that may uccur when saving a binary. - Vacation extension: fixed typo in runtime log message (patch by Julian Cowley). - Fixed use of minus '-' in man pages; it is now properly escaped. - Fixed parser recovery. In particular cases it would trigger spurious errors after an initial valid error and sometimes additional errors were inappropriately ignored. Changelog ManageSieve v0.11.11: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.15. + Implemented ManageSieve QUOTA enforcement. + Added MAXREDIRECTS capability after login. + Implemented new script name rules specified in most recent ManageSieve draft. - Fixed assertion failure occuring with challenge-response SASL mechanisms. - Made configure complain about trying to compile against installed Dovecot headers alone. - Fixed compile warning for compilation against CMUSieve. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… Refer to http://pigeonhole.dovecot.org for more information.

[Dovecot] Delete messages with archivemail
by gstyle 25 Jan '10

25 Jan '10

Hi, I have set up a dovecot imap server (Version 1.0.15 on Debain Lenny). Until know I used courier. Every night I run a script calling archivemail ( http://archivemail.sourceforge.net/) to delete all messages in the Spam folder that are older than 30 days archivemail deletes the files directly in the Maildir folder. I am not using IMAP for this (cause I don't want to store the passwords in plain text). I know that dovecot uses index files to speed up Maildir access. Will there be any problems with the index files when I delete the old spam like this? Cheers Mario

[Dovecot] authentication with userdb and passdb fails
by Jure Lozar 25 Jan '10

Hello I cannot retrieve mail via pop3 using dovecot. I have mail in my mailbox (postfix works fine, maildir contains more then 5 mail files), I use virtual user. I also changed auth to plaintext for debugging purpuse. server: Dovecot 1.0.7 CenoOS 5.4 client: Thunderbird on Kubuntu, username: jure(a)hrabri.org pass:jure I tried different parameters and was closest to success with this: Relevant parts from dovecot.conf: auth default { mechanisms = plain login CRAM-MD5 userdb passwd-file { args = /home/vmail/%d/passwd } passdb passwd-file { args = /home/vmail/%d/shadow } log: Jan 24 16:23:49 hermes dovecot: auth(default): new auth connection: pid=3304 Jan 24 16:23:51 hermes dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=::ffff:192.168.0.144 rip=::ffff:192.168.0.112 resp= Jan 24 16:23:51 hermes dovecot: auth(default): client out: CONT 1 Jan 24 16:23:51 hermes dovecot: auth(default): client in: CONT 1 AGp1cmVAaHJhYnJpLm9yZwBqdXJl Jan 24 16:23:51 hermes dovecot: auth(default): passwd-file /home/vmail/hrabri.org/shadow: Read 1 users Jan 24 16:23:51 hermes dovecot: auth(default): passwd-file(jure@hrabri.org,::ffff:192.168.0.112): lookup: user=jure file=/home/vmail/hrabri.org/shadow Jan 24 16:23:51 hermes dovecot: auth(default): client out: OK 1 user=jure(a)hrabri.org Jan 24 16:23:51 hermes dovecot: auth(default): master in: REQUEST 1 3300 1 Jan 24 16:23:51 hermes dovecot: auth(default): passwd(jure@hrabri.org,::ffff:192.168.0.112): lookup Jan 24 16:23:51 hermes dovecot: auth(default): passwd(jure@hrabri.org,::ffff:192.168.0.112): unknown user Jan 24 16:23:51 hermes dovecot: auth(default): passwd-file /home/vmail/hrabri.org/passwd: Read 1 users Jan 24 16:23:51 hermes dovecot: auth(default): passwd-file(jure@hrabri.org,::ffff:192.168.0.112): lookup: user=jure file=/home/vmail/hrabri.org/passwd Jan 24 16:23:51 hermes dovecot: auth(default): master out: USER 1 jure(a)hrabri.org uid=501 gid=501 home=/home/vmail/hrabri.org/var/spool/mail/jure Jan 24 16:23:51 hermes dovecot: pop3-login: Login: user=<jure(a)hrabri.org>, method=PLAIN, rip=::ffff:192.168.0.112, lip=::ffff:192.168.0.144 Jan 24 16:23:52 hermes dovecot: POP3(jure(a)hrabri.org): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 I don't really understand this log.

Thanks for any help. Jure

[Dovecot] pop3+leave messages on server
by Papp Tamas 24 Jan '10

24 Jan '10

hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's suggested: pop3_uidl_format = %08Xu%08Xv Any idea, what's wrong and what I can do? Thank you very much, tamas

[Dovecot] strange behaviour with seen/unseen messages in virtual folders.
by Matthias Rieber 24 Jan '10

24 Jan '10

Hi, I've a virtual folder that contains unseen messages. When I mark the message and expunge the folder, the message should disappear. This works as expected in alpine. Alpine uses the following commands: 06000010 STORE 1 +Flags (\SEEN) 06000020 EXPUNGE Using roundcube mail, the message wont disappear, when I perform the same steps. RoundCube Mails sends: flg UID STORE 445 +FLAGS (\Seen) exp1 EXPUNGE But the message doesn't dissapear. But I can expunge it with alpine, as long as the folder contains one message. If it contains more messages, some or even all messages won't disappear. When I mark them as unseen/seen in alpine, I can expunge them with alpine. The expunge command send by roundcube mail never expunges any seen message in the unseen folder. Whether it was flagged as seen by alpine nor roundcube mail. kind regards, matthias

[Dovecot] Need simplest method for providing alternate mail location
by Stewart Dean 24 Jan '10

24 Jan '10

I am looking to migrate my DC V1.2 from mbox to maildir format....and want to do this in stages, user group by user group rather than in one horrendous fell swoop....since I'd rather fell things didn't happen. Since I'm running sendmail/procmail, I can change the ~/.procmailrc to change the writing of the INBOX, but the IMAP mail location access info is knottier when one wants to do things a bit at a time. Setting aside for now the matter of converting existing folders, I will be moving: = from a mbox setup with the INBOX in /var/spool/mail/<userid> and the folders in ~/mail = to both in ~/Maildir (unless someone has better ideas) It seems that one could: 1) Change the namespaces in the client...but this is not feasible, because it would means going out to all my 4000+ users desktop and modifying them. 2) Having some sort of db to tell DC it a mail_userdb extra field and override the mail_location in dovecot.conf 3) Perhaps waiting for DC v2.0 which will have this architected in. A) Is there any sense the v2.0 will be coming Real Soon Now and will fulfill #3? B) What's the simplest way to implement #2? I would really rather not install MySQL on my mail server and have all the overhead of installing and managing it when all I need it for is a temporary resource to tell DC where things are until the switchover is complete and Maildir is the default. Is it feasible to do this with an additional flat file in the /etc/passwd mode with some extra fields tacked on that is *only* used for mail location info? Or some other and simple way? My apologies if this is a Stupid Question............. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035
