[Dovecot] Production server migration from mbox to maildir ( need advice )
by Frank Bonnet 13 Feb '09

13 Feb '09

Hello I'm going to change the raid array of my mailhub in fews days/weeks and I wonder if it would be a good idea to take the opportunity of this migration to also change the storage method from mailbox to maildir. I've never used maildir on my production server only on small satellites. So I really need advice of admins that use maildir format on prod servers. My server has approx 3500 users/mailboxes that is approx 450 Gb of data. The OS is Debian etch amd64 but could change also during the migration Opensuse X86_64, CAOS-NSA, FreeBSD 64 are some options. Any infos/experiences welcome, I'll summarize answers. Thanks a lot.

[Dovecot] Bynari Insight connector
by Maarten Bezemer 13 Feb '09

13 Feb '09

Hi, Since IMAP support in Outlook is 'somewhat broken', and Bynari has some promising specifications on their website, I might want to try their product. Does anyone here have any experience with their software? Would you recommend it? Or maybe point me at alternatives? (If there are any.. aside from ditching Outlook of course :-P ) Regards, Maarten Bezemer

[Dovecot] Google Summer of Code
by Charles Marcus 13 Feb '09

13 Feb '09

On another list, someone wrote: > Google Summer of Code is on it's Way. Start collecting students to > throw at projects now! This sounds like a great idea for dovecot too... Timo, maybe there are a few dovecot enhancements that would be good candidates for this? Maybe the test suite? Replication? LMTP server? Anyway, its just a thought... -- Best regards, Charles

Re: [Dovecot] Mapping usernames [RESOLVED]
by Henry 13 Feb '09

Resolved. For others, this is the simple solution which works for me: /etc/dovecot.conf: auth default { userdb passwd-file { args = /etc/passwd } passdb passwd-file { args = scheme="MD5-CRYPT" /etc/dovecot.passwd } } /etc/dovecot.passwd: bob@vhost.com:$1$yAOjs09l$...::::::userdb_user=vabc_bob (the encrypted password "$1$yAOjs09l$..." comes from /etc/shadow) /etc/passwd: vabc_bob:x:20838:2362:bob:/home/mailusers/vabc_bob:/sbin/nologin "abc" could also be the domain ("vhost"), but this might be too large for really long domain names. So we rather use a short unique prefix for each domain.

[Dovecot] file name missing component in error message
by Mike Abbott 13 Feb '09

13 Feb '09

Hi, we occasionally see this error message from maildir_mail_set_cache_corrupted(): "Maildir filename has wrong W value: %s/%s" but the path it prints is missing a component, specifically, the new/cur/tmp component. For example: /Volumes/Spool/user/maildir/12345.M123P123.example.com.... should be /Volumes/Spool/user/maildir/cur/12345.M123P123.example.com.... This is using dovecot-1.1.10. Now I just have to figure out why the file is corrupted in the first place.

[Dovecot] quota - implement via dovecot or postfix? which is easier ?
by Linux Advocate 13 Feb '09

13 Feb '09

Guys, i m new to dovecot. I m setting up a new mailserver and planning to run dovecot and postfix of a centos 5.2 box. I have been reading of quota management from various sources and understand that mail box quota can be implemented either thru postfix ( with vda patch ) or thru dovecot. i rather not patch postfix and m therefore leaning towards quota via dovecot. But after reading some posts ,etc, it seems that the information on the dovecot wiki is inaccurate. A.Any comments on this? B. Am i right in concluding that its easier and better in the long run to implement and enforce quotas thru dovecot instead of postfix? C. The right instructions for implementing quota thru dovecot? Regards, marco.

[Dovecot] CentOS 5 ... again
by Roderick A. Anderson 13 Feb '09

13 Feb '09

At this point I don't think I can do anymore damage to my mail server but I'd like to know if anyone else is using the pre-built RPM files from ATrpms before I install them? http://dl.atrpms.net/all/dovecot-1.1.11-0_90.el5.i386.rpm http://dl.atrpms.net/all/dovecot-sieve-1.1.6-9.el5.i386.rpm Or is there a dovecot-sieve for 1.0.7 from the rpmforge repo? I haven't found it yet but could have sworn I had it before. Thanks, Rod --

[Dovecot] Released Sieve v0.1.3 and ManageSieve v0.11.3 for Dovecot v1.2.beta1
by Stephan Bosch 13 Feb '09

13 Feb '09

Hello Dovecot users, It has been about two months since the last release of the new Sieve implementation and the ManageSieve service for Dovecot v1.2. Therefore, this release contains quite a few changes. It adds new sieve features like the enotify extension and multiscript support. Also, quite a few (user-reported) bugs were fixed since the last release. Changelog Sieve v0.1.3: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= 1.2.beta1 * Made mail address comparison fully case-insensitive. This is particularly noticeable for the :addresses argument of the vacation command. + Finished enotify extension. Currently, only the mailto notification method is implemented. All still needs to be tested thoroughly. + Implemented multiscript support. It is now possible to execute multiple Sieve scripts sequentially. Administrator-controlled scripts can be executed before and after the user's script. Still needs to be tested thoroughly. + Implemented support for configuring the available Sieve extensions. + Made the subaddress extension (partially) configurable using the sieve_subaddress_sep setting, which allows specifying a (multi-charater) separator other than '+'. + Compiler now warns about invalid header field names used for the header and address tests. + Vacation extension now properly generates a References header for the response message. + Added testing of basic result execution to the test suite. Also added support for testing the outgoing messages produced by the Sieve interpreter. + Included execution of the actual result in the sieve-test command line tool. The undocumented sieve-exec tool that existed for this is now removed as planned. + Added support for the now obsolete 'imapflags' extension for backwards compatibility with CMUSieve. This also implements the mark/unmark commands. - Fixed bugs in the regex extension: 1) if an optional match value did not in fact match, subsequent match values would get unexpected indexes. 2) fixed segfault bug occuring when regex is freed. - Fixed bug in the use of the :from agrument for the vacation command. If this address included a phrase part, the response would not be a valid RFC822 message. - Plugged a theoretical security hole occuring when a directory is opened as a Sieve binary. - Cleaned up and fixed various log messages. - Fixed bug in the outgoing address verification. Addresses ending in ',' were erroneously accepted. Changelog ManageSieve v0.11.3: * Changed the SASL service name from "managesieve" into "sieve" as required in the protocol specification. Don't forget to adjust your configuration if your authentication mechanism depends on this service name. * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.beta1. * Adapted to changes in the new Sieve implementation, making this release dependent on Dovecot Sieve >= v0.1.3 if used. The old cmusieve plugin is still supported. + Implemented making the SIEVE and NOTIFY capability fully dynamic, meaning that the sieve_extensions setting that was introduced for the new Sieve plugin properly affects the ManageSieve daemon as well. + Added support for the CHECKSCRIPT command. In terms of the supported commands, the ManageSieve daemon now complies with protocol VERSION 1.0 as listed in the CAPABILITY response. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed handling of ~/ in use of mail-data for script location. - Fixed small problems in the login proxy support. The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
