[Dovecot] Quota not being dispayed correctly in 1.2rc2 (with proof)
by Ralf Hildebrandt 20 Apr '09

User reports: 0% of 640MB -- which cannot be true. I logged in as masteruser and was able to confirm this. I'm getting "0.0% von 640.0MB" == "0.0% of 640.0MB" His maildirsize file is attached.

[Dovecot] dovecot deliver with sieve: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID
by Mathias Gug 18 Apr '09

18 Apr '09

Hi, Running dovecot deliver 1.1.11 with a sieve script (dovecot-sieve 1.1.6 + changeset b9567e94b897) the following messages started to show up in the mail logs for some (spam) messages: deliver(mathiaz): Apr 18 19:03:06 Error: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID 1 deliver(mathiaz): Apr 18 19:03:06 Error: Couldn't fix broken header unfolding deliver(mathiaz): Apr 18 19:03:06 Info: msgid=<01c9548a$f1666dfe$6c822ecf@pillarsx6>: saved mail to INBOX How serious are these? Without changeset b9567e94b897 applied deliver would actually crash and the message would be lost.

[Dovecot] Suggestion: deliver should honor mail_log_prefix
by Mike Abbott 18 Apr '09

18 Apr '09

I can set the log prefix for imap/pop3 processes using mail_log_prefix but the log prefix for deliver is hard-coded. (I'm using 1.1.13.) Deliver should either honor mail_log_prefix or have its own setting (deliver_log_prefix?). What do you think?

[Dovecot] Released Sieve v0.1.5 and ManageSieve v0.11.4 for Dovecot v1.2.rc3 and ManageSieve v0.10.6 for Dovecot v1.1.14
by Stephan Bosch 18 Apr '09

18 Apr '09

Hello Dovecot users, This is a simultaneous release of new versions of Sieve-related software for Dovecot v1.1 and v1.2. Only the Sieve implementation itself has seen significant development. The ManageSieve packages only have small fixes and the ManageSieve patches are updated as usual to match the new Dovecot releases. Changelog Sieve v0.1.5: * Ported the implementation of the Sieve include extension to the latest draft. This means that the import and export commands are replaced by a new command called global. The import and export commands are now DEPRICATED and are mere aliases for the global command. The new specification also adds the :once modifier to the include command. The also newly specified global.* variable namespace is not implemented yet as support for variable namespaces is currently missing. * Did a major rework of the multiscript support for better error handling and made sure that persistent global scripts (sieve_before/sieve_after) are always executed, even when the user does not have a script of his own and a global default is missing. + Provided basic support for the environment extension. Currenly, the name, version and host items are useful. Others are pending. + Improved error message that is presented when an unknown Sieve extension is provided as argument to the require command. It now notifies the user that Sieve core commands do not need to be specified in require. - Fixed bug in includes at levels deeper than one. - Fixed bug in address matching that was caused by the failure to handle group specifications. In Dovecot, these are marked by address items with NULL elements, which causes a segfault if not considered. The group 'undisclosed-recipients:;' in particular triggered this bug. Bug reported by Bernhard Schmidt. Changelog ManageSieve v0.11.4 (Dovecot v1.2.rc3): * Adjusted to changes in the Dovecot signal handler API. Changelog ManageSieve v0.10.6 (Dovecot v1.1.14): - Fixed small problems in the login proxy support. -- The releases are available as follows: Sieve for Dovecot 1.2: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz.sig ManageSieve for Dovecot v1.2 (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… ManageSieve + patch for Dovecot v1.1 (package + patch): http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Mail replication
by Renaud Allard 18 Apr '09

18 Apr '09

Hello, I am running an asynchronously replicated mail setup. 2 servers are each running an smtp server which uses dovecot as the LDA. I am using unison to replicate mail files between servers. Before, I was using Maildir format and after reading so much good papers about the very good performance of dbox format, I decided to switch to dbox. However, I now have a very annoying problem, as mails are created with names like u.1234 and numbers are following each others. So, if there is for example a mail stored as u.1001 on both servers, and now 2 mails arrive at about the same time, 1 on each server. Then, they will both be created as u.1002, that means unison will encounter a conflict as both files are different. So my question would be, is there a way to tell the servers to increment by 2 instead of 1 and have each an offset (like you can do with mysql with auto incrementing tables for example)? That way, with former example, one mail would be stored as u.1002 and the other as u.1003. Thanks

[Dovecot] Logging to see exactly all IMAP commands?
by Johan Persson 18 Apr '09

18 Apr '09

I was wondering if there is some additional logging that can be enabled to make it possible to have Dovecot print all actual IMAP commands it receives in a conversation? /Johan

[Dovecot] Feature Request: Control over IMP IDLE 'OK Still Here' message timings
by Robert Goldsmith 18 Apr '09

18 Apr '09

Hi all, I would like to make a feature request regarding IMAP Idle support. Currently when a client triggers Idle support, Dovecot then sends 'OK Still Here' messages every 2 minutes. This is apparently to prevent NAT systems killing the tcp connection and disconnecting the client. However, while this may be fine for desktop clients, this rapidly drains the battery life of mobile clients such as phones. Unfortunately, the timing control on this behaviour is a c define at the top of cmd-idle.c and is only adjustable at compile-time. I have experimented with this define and find a timeout of 20 minutes between 'OK' messages is perfectly adequate for my system setup and results in a significant battery saving for my Nokia 6120c (increasing from ~ 6 hours to ~ 55 hours from full charge to low battery warning). Therefore, can you please make the timeout changeable from the config file, even if it defaults to the current 2min timing, so admins supporting mobile users can balance battery life with a need to prevent killed tcp connections.

[Dovecot] Shared folders and subscriptions
by Markus Werner 18 Apr '09

18 Apr '09

Hi, I've got a problem with user shared folders and subscriptions. When I try to subscribe a folder, dovecot returns "OK Subscribe completed", but the newly subscribed folder is not listed with LSUB: a1 login test(a)example.com ******* a1 OK [CAP..... a2 list "" "*" * LIST (\HasChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "#User" * LIST (\Noselect \HasChildren) "/" "#User/markus(a)example.com" * LIST (\HasNoChildren) "/" "#User/markus(a)example.com/ForTest" a3 subscribe "#User/markus(a)example.com/ForTest" a3 OK Subscribe completed. a4 lsub "" "*" * LSUB (\Noselect) "/" "#User/markus(a)example.com" Dovecot is 1.2-rc3, namespace configuration as follows: namespace private { separator = / prefix = INBOX/ inbox = yes subscriptions = yes } namespace public { separator = / prefix = "#Shared/" location = maildir:/var/spool/dovecot/sharedfolders:INDEX=~/Maildir/index/public:CONTROL=~/Maildir/control/public subscriptions = yes } namespace shared { separator = / prefix = "#User/%%u/" location = maildir:%%h/Maildir:INDEX=~/Maildir/index/shared/%%u:CONTROL=~/Maildir/control/shared subscriptions = yes list = yes } I tried without CONTROL= directory in the shared namespace, but that made no difference. Contents of the subscriptions (with CONTROL=) file after subscribing: ForTestUser Regards, Markus

[Dovecot] Sieve "redirect"
by James Butler 18 Apr '09

18 Apr '09

Is there an alternative to the "redirect" Sieve capability? For example: if header :contains "Subject" "Listserv" { redirect "list-user1(a)example.com"; redirect "list-user2(a)example.com"; redirect "list-user3(a)example.com"; stop; } How can I do the above without using "redirect"? Unfortunately, "redirect" seems to be unsupported by Dovecot. Thank you. James

[Dovecot] Address Extensions with System Users
by Jeff Grossman 17 Apr '09

17 Apr '09

I am using Dovecot 1.2RC2 with Postfix 2.5.5. Everything is running fine. I would like to start using address extensions and have e-mail automatically filtered into folders based on the folder name after the "+" in the e-mail address. I only use system users, no virtual users. I have Deliver configured in main.cf as: mailbox_command = /usr/local/libexec/dovecot/deliver Everything I can find about setting this up applies to virtual users which I do not have. How do I get Deliver to recognize the address extension. I am sure it is easy, and I apologize for not finding the answer out myself. Here is a copy of my dovecot -n output: # 1.2.rc2: /usr/local/etc/dovecot.conf # OS: Linux 2.6.29-1-amd64 x86_64 Debian squeeze/sid base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/stikman-godaddy.crt ssl_key_file: /etc/ssl/private/stikman-godaddy.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: sieve: sieve
