Hello Dovecot users,

Now that I am not preoccupied anymore, I quickly release a new version
of Pigeonhole for Dovecot v2.2. This consists mainly of bug fixes. One
new feature is that the Sieve plugin will try to pass temporary
failures (e.g. from mail storage) back to LDA/LMTP as much as
possible. However, this change turned out a little bigger than I would
have liked, so experiment with it a bit before you deploy it in
production.

Changelog v0.4.1:

 + Added support for handling temporary failures. These are passed back
   to LDA/LTMP to produce an appropriate response towards the MTA.
 - Sieve storage: Removed PATH_MAX limitation for active symlink. This
   caused problems for GNU/Hurd.
 - Fixed line endings in X-Sieve headers added by redirect command.
 - ManageSieve: Fixed '[' ']' stupidity for response codes (only
   happened before login).
 - Fixed setting name in example-config/conf.d/20-managesieve.conf.
 - Sieve extprograms plugin: Fixed interaction between pipe command and
   remote script service. The output from the script service was never
   read, causing a broken pipe error at the script service. Apparently,
   this was broken since the I/O handling for extprograms was last
   revised.
 - Fixed assertion failure due to datastack problem in message header
   composition.

Update dovecot2-pigeonhole to 0.4.0.

v0.4.0 09-05-2013 Stephan Bosch <stephan@rename-it.nl>

+ Added doveadm-sieve plugin that provides the possibility to synch Sieve
  scripts using doveadm sync along with the user's mailboxes.
+ Added the Sieve extprograms plugin to the main Pigeonhole package. It is
  still a plugin, but it is now included so that a separate compile is no
  longer necessary and distributors are likely to include it. The extprograms
  plugin provides Sieve language extensions that allows executing
  (administrator-controlled) external programs for message delivery,
  message filtering and string manipulation. Refer to
  doc/plugins/sieve_extprograms.txt for more information.
+ Added debug message showing Pigeonhole version at initialization. Makes it
  very clear that the plugin is properly loaded.
+ Finished implementation of the Sieve include extension. It should now
  fully conform to RFC 6609. The main addition is the new :optional tag which
  makes the include command ignore missing included scripts without an error.
+ Finished implementation of the Sieve environment extension as much as
  possible. Environment items "location", "phase" and \ 
"domain" now also
  return a usable value.

Log message:
Drop PKG_DESTDIR_SUPPORT setting, "user-destdir" is default these days.

Log message:
Update to Pigeonhole 0.3.3.

Changelog v0.3.2:

+ sieve-refilter tool: improved man page documentation by explicitly specifying
  the syntax used for mailbox arguments.
+ Sieve: spamtest and virustest extensions: improved trace debugging of score
  calculation.
+ Sieve: made error messages about exceeding the maximum number of actions more
  verbose.
- Sieve tools: fixed problems with running as root: sievec and sieve-dump now
  ignore mail_uid and mail_gid settings when run as root.
- Sieve: fixed bug in action accounting (for limit checking): increase action
  instance count only when an action is actually created.
- Sieve: include extension: fixed namespace separation of :global and :personal
  scripts.
- ManageSieve: fixed segfault bug triggered by CHECKSCRIPT command.
- Fixed linking with ld.gold.
- Fixed several Clang compile warnings and a few potential bugs.

Changelog v0.3.3:

- Fixed compile against installed Dovecot headers. This was broken by the
  ld.gold fix in the previous release.

Log message:
Update to Pigeonhole 0.3.1.

* Added support for retrieving Sieve scripts from dict lookup. This
  means that Sieve scripts can now be downloaded from a database.
  Compiled script binaries are still put on disk somewhere if used.
  The INSTALL documentation is updated with information on this new
  feature and the (backwards-compatible) changes to the configuration.
  Note that his feature is currently not supported for
  sieve_before/sieve_after or script management through ManageSieve.
+ Incorporated the sieve_duplicate plugin into main Pigeonhole tree as
  a normal extension (vnd.dovecot.duplicate). This Dovecot-specific
  extension adds the ability to check for duplicate deliveries based
  on message ID. Specification can be found in:
  doc/rfc/spec-bosch-sieve-duplicate.txt
+ Added support for specifying multiple sieve_before and sieve_after
  paths. This adds much more flexibility to the multiscript
  configuration. One application is to have user-specific Sieve
  scripts outside the user's normal control through ManageSieve.
+ Added a "session ID" string for managesieve connections, available in
  %{session} variable (analogous to Dovecot change).
- Fixed several small issues, including a few potential segfault bugs,
  based on static source code analysis.
- ManageSieve: changed use of EPROTO error to EIO in ManageSieve
  string stream implementation because it is apparently not known in
  BSD.
- Gave stamp.h.in (needed for autotools) some content to prevent it
  from disappearing in patch files.
- Fixed bug that caused a SunStudio CC compile failure (reported by
  Piotr Tarnowski).

Log message:
Update to Pigeonhole 0.3.0 for Dovecot 2.1.

* Renamed sieve_global_path setting to sieve_default for clarity. Old name is
  still recognized for backwards compatibility. Support for the ancient (pre
  v1.1) name for this setting "global_script_path" is now dropped.
* Added means to prohibit use of redirect action. Setting sieve_max_redirects
  to 0 now means that redirect is disallowed in stead of unlimited. Default
  value remains four.
* Fixed interaction of Sieve include extension with ManageSieve. It is updated
  to match new requirements in the draft include specification. Missing
  included scripts are no longer an error at upload time.
* Updated RFC2822 header field body verification to exclude non-printing
  characters (RFC5322). Only Sieve actions that can create unstructured header
  values (currently enotify/mailto and editheader) are affected by this change.
+ Completed sieve-filter tool to a useful state. The sieve-filter tool provides
  a means to (re)filter messages in a mailbox through a Sieve script.
+ Implemented the Sieve editheader extension. It is now possible to add and
  remove message headers from within Sieve.
+ ManageSieve: added support for reading quoted and literal strings as a
  stream. Fixes support for handing large SASL responses (analogous to similar
  changes in Dovecot). It is now also allowed to use a quoted string for the
  PUTSCRIPT script argument.
+ Added code to cleanup tmp directory in Sieve storage directory (sieve_dir)
  every once in a while.
+ Added support for substituting the entire message during Sieve processing.
  This is used for the filter action provided by the new sieve_extprograms
  plugin (provided separately for now). The filter action allows passing the
  message through an external program.
+ Added support for restricting certain Sieve language extensions to
  (admin-controled) global scripts. Restricted extensions can be configured
  using the new sieve_global_extensions setting. This is particularly useful
  for some of the Dovecot-specific (plugin-based) Sieve extensions, that can
  be somewhat hazardous when under direct control of users (e.g.
  sieve_extprograms).

Log message:
Update to Pigeonhole 0.2.5:

+ Sieve vacation extension: made discard message for implicit
  delivery more verbose
- The sieve-test tool: mixed up original and final envelope recipient
  in implementation of command line arguments.
- Sieve vacation extension: resolved FIXME regarding the use of
  variables in the :handle argument. Variables are now handled
  correctly.
- Sieve body extension: fixed handling of :content "message/rfc822".
  This now yields the headers of the embedded message as required by
  the specification. Handling of :content "multipart" remains to be
  fixed.
- LDA Sieve plugin: fixed problem with recipient_delimiter
  configuration. Now it falls back to global recipient_delimiter
  setting if plugin/recipient_delimiter is not set.

Log message:
Update pigeonhole plugin to 0.2.4.

Changelog:

+ Vacation extension: finally added support for using the original
   recipient in vacation address check. It is also possible to disable
   the recipient address check entirely. Check doc/vacation.txt for
   configuration information.
+ Include extension: made limits on the include depth and the total
   number of included scripts configurable. Check doc/include.txt for
   configuration information.
+ Implemented ihave extension. This allows checking for the availability
   of Sieve language extensions at 'runtime'. Actually, this is checked
   at compile time. At runtime the interpreter checks whether extensions
   that were not previously available are still unavailable. If the
   situation changed, the script is re-compiled and the ihave tests are
   evaluated again.
+ Sieve: optimized compilation of tests that yield constant results
   (i.e. known at compile tme), such as 'true' and 'false'. No code is
   produced anymore for script sections that are never executed. Also,
   semantics are not verified anymore in uncompiled script sections.
+ Made vnd.dovecot.debug extension available to the LDA plugin instead
   of only the command line tools.
+ Sieve: redirect action now adds X-Sieve-Redirected-From header
   (mainly for people using SPF/SRS).
- Sieve: fixed bug in handling flags and keywords; in case of error an
   assertion was triggered.
- Script storage: improved handling of unconfigured user home directory.
   Originally this would produce an unhelpful error message.
- Imap4flags extension: prevent forcibly enabling imap4flags when
   imapflags is enabled.
- Fixed various -Wunused-but-set-variable compiler warnings.
- Include extension: forgot to check variable identifier syntax for
   'global' command.
- Sieve: fixed debug mode; no messages were logged in some situations.
- sievec tool: forgot to enable -D (debug) parameter.
