dovecot2-pigeonhole: updated to 0.5.2

v0.5.2:
+ 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
  doc/plugins/imap_filter_sieve.txt.
- 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
  characters.
- 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.

dovecot2-pigeonhole: update to 0.5.1

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

  - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve
    script.
  - 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.

Log message:
Add p11-kit to gnutls/bl3.mk and bump dependencies.

Log message:
mail/dovecot2-pigeonhole: update to 0.5.0.1

Changelog v0.5.0.1:

- imap4flags extension: Fix binary corruption occurring when
  setflag/addflag/removeflag flag-list is a variable.
- sieve-extprograms plugin: Fix segfault occurring when used in
  IMAPSieve context.

Log message:
mail/dovecot2-pigeonhole: Bump PKGREVISION for the dovecot2 bl3 ABI change.

Log message:
Update mail/dovecot2-pigeonhole to 0.5.0.

* editheader extension: The implementation of header modifications is
  heavily updated. Although the functionality has not changed, the
  underlying code was updated to address several static analysis
  warnings, runtime integer arithmetic warnings (Clang), and to match
  updates in the Dovecot stream API.
+ variables extension: Made the maximum scope and variable size
  configurable.
+ subaddress: Support multiple recipient_delimiters.
- enotify extension: mailto method: Fixed parsing of mailto URI with
  only a header part.
- enotify plugin: mailto method: Make sure the "From:" header is set to
  a usable address and not "(null)".
- Fixed writing address headers to outgoing messages. Sometimes headers
  were MIME-encoded twice, yielding invalid results.

Log message:
dovecot2-pigeonhole: update to 0.4.21

v0.4.21:

* redirect action: Always set the X-Sieve-Redirected-From header to
  sieve_user_email if configured. Before, it would use the envelope recipient
  instead if available, which makes no sense if the primary e-mail address is
  available.
+ vacation extension: Allow ignoring the envelope sender while composing the
  "To:" header for the reply. Normally, the "To:" header is \ 
composed from
  the address found in the "Sender", "Resent-From" or \ 
"From" headers that is
  equal to the envelope sender. If none is then found, the bare envelope
  sender is used. This change adds a new setting
  "sieve_vacation_to_header_ignore_envelope". With this setting \ 
enabled, the
  "To:" header is always composed from those headers in the source message.
  The new setting thus allows ignoring the envelope, which is useful e.g.
  when SRS is used.
+ vacation extension: Compose the "To:" header from the full sender address
  found in the first "Sender:", "From:" or \ 
"Resent-From:" header. Before, it
  would create a "To:" header without a phrase part. The new behavior is
  nicer, since the reply will be addressed to the sender by name if possible.
- LDA Sieve plugin: Fixed sequential execution of LDAP-based scripts. A
  missing LDAP-based script could cause the script sequence to exit earlier.
- sieve-filter: Removed the (now) duplicate utf8 to mutf7 mailbox name
  conversion. This caused problems with mailbox names containing UTF-8
  characters. The Dovecot API was changed years ago, but apparently
  sieve-filter was never updated.

Log message:
Update dovecot2-pigeonhole to 0.4.20.

Changelog v0.4.20:

+ Made the retention period for redirect duplicate identifiers
  configurable. For accounts that perform many redirects, the lda-dupes
  database could grow to impractical sizes. Changed the default
  retention period from 24 to 12 hours.
- sieve-filter: Fixed memory leak: forgot to clean up script binary at
  end of execution. Normally, this would merely be an inconsequential
  memory leak. However, when the script comes from an LDAP storage, this
  would cause io leak warnings.
- managesieve-login: Fixed handling of AUTHENTICATE command. A second
  authenticate command would be parsed wrong. This problem was caused by
  changes in the previous release.
- LDA Sieve plugin: Fixed minor memory leak caused by not cleaning up
  the sieve_discard script.

Log message:
Changelog v0.4.19:

* This release adjusts Pigeonhole to several changes in the Dovecot API,
 making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole
 will produce compile warnings with the recent Dovecot releases (but
 still work ok).
- Fixed bug in handling of implicit keep in some cases. Implicit
 side-effects, such as assigned flags, were not always applied
 correctly. This is in essence a very old bug, but it was exposed by
 recent changes.
- include extension: Fixed segfault that (sometimes) occurred when the
 global script location was left unconfigured.

Log message:
Update dovecot2-pigeonhole to 0.4.18 for dovecot2 2.2.28.

v0.4.18 12-04-2017 Stephan Bosch <stephan@rename-it.nl>

+ imapsieve plugin: Implemented the copy_source_after rule action. When this
  is enabled for a mailbox rule, the specified Sieve script is executed for
  the message in the source mailbox during a "COPY" event. This \ 
happens only
  after the Sieve script that is executed for the corresponding message in the
  destination mailbox finishes running successfully.
+ imapsieve plugin: Added non-standard Sieve environment items for the source
  and destination mailbox.
- multiscript: The execution of the discard script had an implicit "keep",
  rather than an implicit "discard".
