./mail/dovecot2-pigeonhole, Support for the Sieve language and the ManageSieve protocol

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.5.6, Package name: dovecot-pigeonhole-0.5.6, Maintainer: adam

This package is part of the Pigeonhole project (http://pigeonhole.dovecot.org).
It adds support for the Sieve language (RFC 5228) and the ManageSieve protocol
(RFC 5804) to the Dovecot Secure IMAP Server.

The Sieve language is used to specify how e-mail needs to be processed. By
writing Sieve scripts, users can customize how messages are delivered, e.g.
whether they are forwarded or stored in special folders. Unwanted messages can
be discarded or rejected, and, when the user is not available, the Sieve
interpreter can send an automated reply. Above all, the Sieve language is meant
to be simple, extensible and system independent. And, unlike most other mail
filtering script languages, it does not allow users to execute arbitrary
programs. This is particularly useful to prevent virtual users from having full
access to the mail store. The intention of the language is to make it impossible
for users to do anything more complex (and dangerous) than write simple mail

Using the ManageSieve protocol, users can upload their Sieve scripts remotely,
without needing direct filesystem access through FTP or SCP. Additionally,
aManageSieve server always makes sure that uploaded scripts are valid,
preventing compile failures at mail delivery.

This package provides Sieve support as a plugin to Dovecot's Local Delivery
Agent (LDA) and Dovecot's LMTP service. The ManageSieve protocol is provided is
an additional service, next to Dovecot's own POP3 and IMAP services.

mail/dovecot2-pigeonhole: update to 0.5.6

Update dovecot2-pigeonhole to 0.5.6.

v0.5.6 2019-04-30  Aki Tuomi <aki.tuomi@open-xchange.com>

	+ sieve: Redirect loop prevention is sometimes ineffective. Improve
	  existing loop detection by also recognizing the
	  X-Sieve-Redirected-From header in incoming messages and dropping
	  redirect actions when it points to the sending account. This header
	  is already added by the redirect action, so this improvement only
	  adds an additional use of this header.
	- sieve: Prevent execution of implicit keep upon temporary failure
	  occurring at runtime.

mail/dovecot2-pigeonhole: update to 0.5.5

Update dovecot2-pigeonhole to 0.5.5 for dovecot 2.3.5.

v0.5.5 2019-03-05  Stephan Bosch <stephan@rename-it.nl>

	+ IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which
	  causes messages discarded by an IMAPSieve script to be expunged
	  immediately, rather than only being marked as "\Deleted" (which is
	  still the default behavior).
	- IMAPSieve: Fix panic crash occurring when a COPY command copies
	  messages from a virtual mailbox where the source messages originate
	  from more than a single real mailbox.
	- imap4flags extension: Fix deleting all keywords. When the action
	  resulted in all keywords being removed, no changes were actually
	- variables extension: Fix truncation of UTF-8 variable content. The
	  maximum size of Sieve variables was enforced by truncating the
	  variable string content bluntly at the limit, but this does not
	  consider UTF-8 code point boundaries. This resulted in broken UTF-8
	  strings. This problem also surfaced for variable modifiers, such as
	  the ":encodeurl" modifier provided by the Sieve "enotify" \ 
	  In that case, the resulting URI escaping could also be truncated
	- IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve
	  scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that
	  modify the message, stored the message a second time, rather than
	  replacing the originally stored unmodified message.
	- Fix segmentation fault occurring when both the sieve_extprograms
	  plugin (for the Sieve interpreter) and the imap_filter_sieve plugin
	  (for IMAP) are loaded at the same time. A symbol was defined by both
	  plugins, causing a clash when both were loaded.

dovecot2-pigeonhole: updated to 0.5.4

* Adjustments to several changes in Dovecot v2.3.4 make this Pigeonhole
  release dependent on that Dovecot release; it will not compile against
  older Dovecot versions. And, conversely, you need to upgrade
  Pigeonhole when upgrading Dovecot to v2.3.4.
* The changes regarding the default postmaster_address in Dovecot v2.3.4
  mainly apply to Pigeonhole. The new default should work for all
  existing installations, thereby fixing several reported v2.3/v0.5
  migration problems.
- IMAP FILTER=SIEVE capability: Fix assert crash occurring when running
  UID FILTER on a Sieve script with errors.

Log message:
dovecot2-pigeonhole: updated to 0.5.3

Changelog v0.5.3:
- Fix assertion panic occurring when managesieve service fails to open
  INBOX while saving a Sieve script. This was caused by a lack of
  cleanup after failure.
- Fix specific messages causing an assert panic with actions that
  compose a reply (e.g. vacation). With some rather weird input from the
  original message, the header folding algorithm (as used for composing
  the References header for the reply) got confused, causing the panic.
- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing.
  After finishing reading the Sieve script, the command parsing
  sometimes didn't continue with the search arguments. This is a time-
  critical bug that likely only occurs when the Sieve script is sent in
  the next TCP frame.

dovecot2-pigeonhole: updated to 0.5.2

+ Implement plugin for the a vendor-defined IMAP capability called
  "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering
  in IMAP. More information can be found in
- The Sieve addess test caused an assertion panic for invalid addresses
  with UTF-8 codepoints in the localpart. Fixed by properly detecting
  invalid addresses with UTF-8 codepoints in the localpart and skipping
  these like other invalid addresses while iterating addresses for the
  address test.
- Make the length of the subject header for the vacation response
  configurable and enforce the limit in UTF-8 codepoints rather than
  bytes. The subject header for a vacation response was statically
  truncated to 256 bytes, which is too limited for multi-byte UTF-8
- Sieve editheader extension: Fix assertion panic occurring when it is
  used to manipulate a message header with a very large header field.
- Properly abort execution of the sieve_discard script upon error.
  Before, the LDA Sieve plugin attempted to execute the sieve_discard
  script when an error occurs. This can lead to the message being lost.
- Fix the interaction between quota and the sieve_discard script. When
  quota was used together with a sieve_discard script, the message
  delivery did not bounce when the quota was exceeded.

Log message:
dovecot2-pigeonhole: update to 0.5.1

v0.5.1 28-03-2018  Stephan Bosch <stephan@rename-it.nl>

  - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve
  - editheader extension: Corrected the stream position calculations
    performed while making the modified message available as a stream.
    Pigeonhole Sieve crashed in LMTP with an assertion panic when the
    Sieve editheader extension was used before the message was redirected.
    Experiments indicate that the problem occurred only with LMTP and that
    LDA is not affected.
  - fileinto extension: Fix assert panic occurring when fileinto is used
    without being listed in the require line, while the copy extension is
    listed there. This is a very old bug.
  - imapsieve plugin: Do not assert crash or log an error for messages
    that disappear concurrently while applying Sieve scripts. This event
    is now logged as a debug message.
  - Sieve extprograms plugin: Large output from "execute" command crashed
    delivery. Fixed buffering issue in code that handles output from the
    external program.
