http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz.sig * dovecot-lda: Removed use of non-standard Envelope-To: header as a default for -a. Set lda_original_recipient_header=Envelope-To to returns the old behavior. + Added support for reverse quota warnings (i.e. when quota goes back under the limit). This is enabled by adding '-' to beginning of quota_warning value. Based on patch by Jeroen Koekkoek. + dovecot-lda: Added lda_original_recipient_header setting, which is used for getting original recipient if -a isn't used. + dovecot-lda: Added -r parameter to specify final recipient address. (It may differ from original address for e.g. aliases.) + Maildir: uidlist file can now override message's GUID, making it possible for multiple messages in a mailbox to have the same GUID. This also fixes dsync's message conflict resolution. - dovecot-lda: If destination user isn't found, exit with EX_NOUSER, not EX_TEMPFAIL. - dsync: Fixed handling \Noselect mailboxes - Fixed an infinite loop introduced by v2.0.2's message parser changes. - Fixed a crash introduced by v2.0.2's istream-crlf changes.

Released Pigeonhole v0.2.0 for Dovecot v2.0.2
by Stephan Bosch 10 Sep '10

10 Sep '10

Hello Dovecot users, I have finally finished the first release of Pigeonhole for Dovecot v2.0. The most notable change from previous Dovecot v1.2 Sieve/ManageSieve releases is that all is now integrated in a single package and there is no need to patch Dovecot anymore to gain ManageSieve support. Changelog v0.2.0: * Merged Sieve and ManageSieve packages into a single Pigeonhole package. There is also no need to patch Dovecot anymore to gain ManageSieve support. Version numbering of previous Sieve releases is continued as v0.2.0. The sources originally branched off from Sieve v0.1.5 and ManageSieve v0.11.4, but the NEWS history of much more recent releases for Dovecot v1.2 is included since these changes are all included in this release as well. * The ManageSieve service now binds to TCP port 4190 by default due to the IANA port assignment for the ManageSieve service. When upgrading from v1.2, this should be taken into account. The service can be configured manually to listen on both 2000 and 4190. * The Dovecot configuration now calls the ManageSieve protocol 'sieve' in stead of 'managesieve' because it is registered as such with IANA. The binaries and the services are still called managesieve and managesieve-login. * The binary representation of a compiled Sieve script is updated to include source code locations of all commands and arguments. This is implemented in a similar manner as such debug information is included in some system executables and libraries (DWARF-like). Run-time errors can now always refer to the proper line number in the Sieve source script. * The Sieve plugin is adapted to work properly with the new LMTP service introduced with Dovecot v2.0. The same plugin is used for both LDA and LMTP. * The 'sieve_subaddress_sep' setting for the Sieve subaddress extension is now known as 'recipient_delimiter'. Although the deprecated sieve_subaddress_sep setting is still recognized for backwards compatibility, it is recommended to update the setting to the new name, since the new LMTP service also use the recipient_delimiter setting. * ManageSieve: changed default IMPLEMENTATION capability to from 'Dovecot' to 'Dovecot Pigeonhole'. * Renamed the sieved tool to sieve-dump. The original name was somewhat confusing. * Updated man pages to match style and structure of new Dovecot man pages. * Made testsuite commands more uniform and cleaned up many of the testsuite scripts. Some minor new tests were added in the process. + Simplified string matching API to use abstract string lists as data sources. This will also make implementing the index extension easier in the future. + Significantly improved trace debugging with the sieve-test tool. The full execution of the script can be examined, including the matched values and keys of the respective Sieve test commands. The executed statements are listed with their line number (and code address when requested). The level of detail is configurable from the command line. + The SIEVE and NOTIFY capabilities reported by the ManageSieve protocol can now be configured manually. If left unconfigured, the capabilities are determined from the default Sieve and ManageSieve configuration. User-specific capabilities aren't reported until after authentication. + Significantly improved file error handling. This means that administrators get a more useful and informative log message when file operations fail. The most notable example is that when the LDA Sieve plugin is trying to store a binary for a global script, the resulting failure message also points the administrator towards pre-compiling the script with sievec. + Added runtime argument value checking for several commands (redirect, date, vacation). When variables are used, these checks cannot be performed at compiletime. A proper runtime error now is produced when invalid data is encountered. + UTF8 validity of fileinto command argument is now checked either at compile time or at runtime. Previously, it was not checked until the store action was executed. + Validity of IMAP flags for the imap4flags extension is now checked also at runtime. Previously, it was not checked until the store action was executed. + Simplified and restructured error handling. Also made sure that user-caused errors are no longer written to the Dovecot master/LDA log. - Multiscript: fixed duplicate implicit keep caused by erroneous execution state update. - Prevented assertion failure due to currupt binary string representation. If the string was missing a final \0 character an assertion was produced in stead of a binary corruption error. - Imap4flags: fixed bug in setflag command; when parameter was a stringlist, only the last item was actually set. - Variables extension: fixed :length set modifier to recognize utf8 characters in stead of octets. - Testsuite: prevented innocent warning messages, i.e. those that are part of the test, from showing up by default. - ManageSieve/Sieve storage: fixed error handling of PUTSCRIPT commmand; save commit errors would not make the command fail. - ManageSieve: enforced protocol syntax better with some of the commands; some commands allowed spurious extra arguments. - Fixed Sieve script name checking to properly handle length limit and added 0x00ff as invalid character. - Removed spurious old stdio.h (top) includes; these caused compile issues on specific systems. - Fixed default Sieve capability (as reported by ManageSieve): extra extensions spamtest, spamtestplus and virustest were enabled by default. These should, however, only be enabled when properly configured and there is no default configuration. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.0.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.0.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this first release and don't hesitate to notify me when there are any problems. The bugfixes above are also applied to the Dovecot v1.2 Sieve and ManageSieve sources and I'll produce new releases for those in the next few days. Oh.. and if anyone is wondering what those duplicate notifications are on the dovecot-cvs list.. well.. oops. :) Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.0.2 released
by Timo Sirainen 08 Sep '10

08 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.2.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.2.tar.gz.sig Many small fixes and logging improvements, but most importantly fixes LMTP with Maildir. * vpopmail support is disabled for now, since it's broken. You can use it via checkpassword support or its sql/ldap database directly. - maildir: Fixed "duplicate uidlist entry" errors that happened at least with LMTP when mail was delivered to multiple recipients - Deleting ACLs didn't cause entries to be removed from acl_shared_dict - mail_max_lock_timeout setting wasn't working with all locks - auth_cache_size setting's old-style value wasn't autoconverted and it usually also caused a crash

v2.0.1 released

24 Aug '10

http://dovecot.org/releases/2.0/dovecot-2.0.1.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.1.tar.gz.sig Some small fixes mainly, but since people aren't reporting much bugs for v2.0.0 anymore maybe v2.0.1 release will change that. :) Some of the more important changes since v2.0.0 are: * When dsync is started as root, remote dsync command is now also executed as root instead of with dropped privileges. - IMAP: QRESYNC parameters for SELECT weren't handled correctly. - UTF-8 string validity checking wasn't done correctly (e.g. mailbox names in Sieve fileinto) - dsync: Fixed a random assert-crash with remote dsyncing

v2.0.0 released
by Timo Sirainen 16 Aug '10

16 Aug '10

http://dovecot.org/releases/2.0/dovecot-2.0.0.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.0.tar.gz.sig As promised last Friday, here's the v2.0.0 release finally. I'm cautiously optimistic that v2.0.1 won't (have to) be released for a few weeks, since there was quite a lot of testing and fixing going on in the RC stage. Remember to read http://wiki2.dovecot.org/Upgrading/2.0 before upgrading from v1.x. Although there is automatic config conversion, it can't handle everything, so reserve some extra time for upgrading. If you find an upgrade problem that isn't listed on the wiki page, please add it there or email Dovecot mailing list about it. Pigeonhole Sieve and ManageSieve support can now be installed without patching Dovecot. Unfortunately there isn't a Pigeonhole release yet for v2.0, but its Mercurial code tree should be quite stable. See http://wiki2.dovecot.org/Pigeonhole There are no changes since v2.0.rc6. The largest changes since v1.2 are: * Dovecot uses two system users for internal purposes now by default: dovenull and dovecot. You need to create the dovenull user or change default_login_user setting. * Global ACLs are now looked up using namespace prefixes. For example if you previously had INBOX. namespace prefix and a global ACL for "INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of "Sent" as before. * Maildir: File permissions are no longer based on dovecot-shared file, but the mailbox directory. + Redesigned master process. It's now more modular and there is less code running as root. + Configuration supports now per-local/remote ip/network settings. + dsync utility does a two-way mailbox synchronization. + LMTP server and proxying. + Added mdbox (multi-dbox) mail storage backend. + doveadm utility can be used to do all kinds of administration functions. Old dovecotpw and *view utilities now exist in its subcommands. + imap and pop3 processes can now handle multiple connections. + IMAP: COMPRESS=DEFLATE is supported by imap_zlib plugin + director service helps NFS installations to redirect users always to same server to avoid corruption

v2.0.rc6 released
by Timo Sirainen 13 Aug '10

13 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz.sig I expect this to be the last release candidate. Unless release critical bugs are reported, I'll update the version number to v2.0.0 on Monday morning without any other changes. Since rc5 there have been mainly some small fixes and some error message improvements. The only (somewhat) important fixes are: - dict quota didn't always decrease quota when messages were expunged - Shared INBOX wasn't always listed with FS layout

v2.0.rc5 released
by Timo Sirainen 10 Aug '10

10 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz.sig Unfortunately v2.0.0 has to be delayed a while longer, because I found that there were still problems in plugin hook handling when using more than 2 plugins. Hopefully it's now finally fully fixed, but I'd like to be sure and wait for one more week to see if people can find a problem with some plugin combination. - Using more than 2 plugins could have caused broken behavior (more fixes for this) - Listescape plugin fixes - mbox: Fixed a couple of assert-crashes - mdbox: Fixed potential assert-crash when saving multiple messages in one transaction.

v2.0.rc4 released
by Timo Sirainen 04 Aug '10

04 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc4.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc4.tar.gz.sig I'm planning to release rc5 maybe this Friday or weekend, and if there are no serious bugs just change the version number to v2.0.0 a day or two later. Largest changes since rc3: + director: Added director_doveadm_port for accepting doveadm TCP connections. + doveadm: Added client/server architecture support for running mail commands. Enable this by setting doveadm_worker_count to non-zero. + mail-log: Added support for mailbox_create event. + imap_capability = +XFOO BAR can be used to add capabilities instead of replacing the whole capability string. + virtual storage: Added support for IDLE notifications. - doveadm mailbox status: Fixed listing non-ASCII mailbox names. - doveadm fetch: Fixed output when fetching message header or body - doveadm director map/add/remove: Fixed handling IP address as parameter. - dsync: A few more fixes

v1.2.13 released
by Timo Sirainen 23 Jul '10

23 Jul '10

http://dovecot.org/releases/1.2/dovecot-1.2.13.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.13.tar.gz.sig This release fixes a bug in ACL plugin, which could be considered a security bug: If Maildir is used with default settings (INBOX is same as Maildir root dir) and user set some ACLs to INBOX, those ACLs were copied to all newly created mailboxes. This should have been done only for "default ACLs", but with Maildir the INBOX directory is the same as the default ACL directory, so this mixup happened. This bug exists only in v1.2.x releases. Other fixes: - Fixed iconv() crash when it was processing several kilobytes of broken continuous input. This mainly could have caused a problem with IMAP SEARCH. Possibly also with some Sieve checks. - If MIME encoded-words contained line feeds, Dovecot logged cache corruption errors. - mbox: Renaming mailbox under newly created dir didn't move index directory. - mbox: When generating envelope to From_-line, don't append a second @owndomain if username already has one.
