  one dsync side doesn't support mail GUIDs (i.e. imapc), there is no

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

mail/dovecot, mail/dovecot-pigeonhole: Upgrade to 2.3.19, 0.5.19

Dovecot Changelog:
+ Added mail_user_session_finished event, which is emitted when the mail
  user session is finished (e.g. imap, pop3, lmtp). It also includes
  fields with some process statistics information.
  See https://doc.dovecot.org/admin_manual/list_of_events/ for more
  information.
+ Added process_shutdown_filter setting. When an event matches the filter,
  the process will be shutdown after the current connection(s) have
  finished. This is intended to reduce memory usage of long-running imap
  processes that keep a lot of memory allocated instead of freeing it to
  the OS.
+ auth: Add cache hit indicator to auth passdb/userdb finished events.
  See https://doc.dovecot.org/admin_manual/list_of_events/ for more

mail/dovecot, mail/dovecot-pigeonhole: update to 2.3.18, 0.5.18 respectively

Dovecot ChangeLog:
* Removed mail_cache_lookup_finished event. This event wasn't especially
  useful, but it increased CPU usage significantly.
* fts: Don't index inline base64 encoded content in FTS indexes using
  the generic tokenizer. This reduces the FTS index sizes by removing
  input that is very unlikely to be searched for. See
  https://doc.dovecot.org/configuration_manual/fts/tokenization for
  details on how base64 is detected. Only applies when using libfts.
* lmtp: Session IDs are now preserved through proxied connections, so
  LMTP sessions can be tracked. This slightly changes the LMTP session
  ID format by appending ":Tn" (transaction), ":Pn" (proxy connection)
  and ":Rn" (recipient) counters after the session ID prefix.
+ Events now have "reason_code" field, which can provide a list of

  100 milliseconds.
* dict: Lines logged by the dict process now contain the dict name as
  the prefix.
* lib-index: mail_cache_fields, mail_always_cache_fields and
  mail_never_cache_fields now verifies that the listed header names are
  valid. Especially the UTF8 "–" character has sometimes been wrongly
  used instead of the ASCII "-".
+ *-login: Added login_proxy_rawlog_dir setting to capture
  rawlogs between proxy and backend.
+ dict: The server process now keeps the last 10 idle dict backends

mail/dovecot, mail/dovecot-pigeonhole: upgrade to 2.3.11.3 and 0.5.11,
repectively.

dovecot changelog:
* CVE-2020-12100: Parsing mails with a large number of MIME parts could
  have resulted in excessive CPU usage or a crash due to running out of
  stack memory.
* CVE-2020-12673: Dovecot's NTLM implementation does not correctly check

mail/dovecot-pigeonhole: upgrade to 0.5.10.

- just to keep version numbers consistent
- fix some issues caused by a recent commit.

mail/dovecot: update to 2.3.10.

ChangeLog:
* Disable retpoline migitations by default. These can cause severe
  performance regressions, so they should be only enabled when
  applicable.
* IMAP MOVE now commits transactions in batches of 1000 mails. This
  helps especially with lazy_expunge when moving a lot of mails. It
  mainly avoids situations where multiple IMAP sessions are running the
  same MOVE command and duplicating the mails in the lazy_expunge folder.
  With this change there can still be some duplication, but the MOVE
  always progresses forward. Also if the MOVE fails at some point, the
  changes up to the last 1000 mails are still committed instead of
  rolled back. Note that the COPY command behavior hasn't changed,
  because it is required by IMAP standard to be an atomic operation.

mail/dovecot: upgrade to 2.3.9.2,

* CVE-2019-19722: Mails with group addresses in From or To fields caused
crash in push notification drivers.

Update dovecot to 2.3.1, and dovecot-pigeonhole to 0.5.1

This is a very large update, and it WILL require manually
updating existing conf files, though the changes to do so
are not extensive. Updating instructions are here:

	https://wiki2.dovecot.org/Upgrading/2.3

Additionally there are various cleanups to the dovecot rc(8)
script, and support for a LUA scripting interface for dovecot.

The decision was made not to import the 2.3.0 or 2.3.0.1 releases
here, due to the number of existing bugs. ler and I have been
dogfooding it for months now, and all of the bugs I've encountered
are fixed in this 2.3.1 release.

This update is the result of many, many hours of collborative work
between ler and me, and the input of many people on the freebsd-ports
list.

mail/dovecot-pigeonhole: upgrade to 0.4.23:
- 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 log an error for messages that disappear
  concurrently while applying Sieve scripts. This is a further
  improvement on the imapsieve fix in the previous release (which fixed
  a panic). This event is now logged as a debug message.

Update dovecot to 2.2.35, and bump pigeonhole

    - charset_alias: compile fails with Solaris Studio, reported by
      John Woods.
    - Fix local name handling in v2.2.34 SNI code, bug found by cPanel.
    - imapc: Don't try to add mails to index if they already exist there.
    - imapc: If email is modified in istream_opened hook, mail size isn't
      updated.
    - lib-dcrypt: When reading encrypted data, more data would not be
      read if buffer was not consumed causing panic or hang.
    - notify: When notify plugin is used and transaction commit fails in
      dsync, crash occurs.
    - sdbox: When delivering to a mailbox that is over quota, temp files
      are not cleaned up when saving or copying fails.

mail/dovecot-pigeonhole: upgrade to v0.4.22.

Changelog:
- Fixed filesystem path handling problem: sieve plugin could have
  assert-crashed with specific path lengths with: "Panic: file
  realpath.c: line 86 (path_normalize): assertion failed: (npath_pos +
  1 < npath + asize)".
- Sieve extprograms plugin: Large output from "execute" command crashed
  delivery. Fixed buffering issue in code that handles output from the
  external program.
- editheader extension: Extensively reworked the low-level
  implementation of adding and removing headers. This solves a few
  integer arithmetic problems reported by Clang runtime checks, but also
  improves code structure and reliability in general.
- imapsieve: Fix assert crash occurring when selected messages are
  expunged concurrently by the time Sieve filter is to be applied.
- imap4flags extension: Fix binary byte-code corruption occurring when
  the setflag, addflag, or removeflag command's flag-list is a variable.
- enotify extension: mailto method: Fixed parsing of mailto URI with
  only a header part.
- enotify extension: mailto method: Make sure "From:" header is set to a
  usable address and not "(null)".
- Fixed writing address headers to outgoing messages. It sometimes
  erroneously applied another layer of MIME header encoding.

Update dovecot to 2.2.34, and bump pigeonhole.

 * CVE-2017-15130: TLS SNI config lookups may lead to excessive
   memory usage, causing imap-login/pop3-login VSZ limit to be reached
   and the process restarted. This happens only if Dovecot config has
   local_name { } or local { } configuration blocks and attacker uses
   randomly generated SNI servernames.
 * CVE-2017-14461: Parsing invalid email addresses may cause a crash or
   leak memory contents to attacker. For example, these memory contents
   might contain parts of an email from another user if the same imap
   process is reused for multiple users. First discovered by Aleksandar
   Nikolic of Cisco Talos. Independently also discovered by "flxflndy"
   via HackerOne.
 * CVE-2017-15132: Aborted SASL authentication leaks memory in login
   process.

mail/dovecot: update to 2.2.33.2.

One more patch release with some fixes:

- doveadm: Fix crash in proxying (or dsync replication) if remote is
  running older than v2.2.33
- auth: Fix memory leak in %{ldap_dn}
- dict-sql: Fix data types to work correctly with Cassandra

bump dovecot-pigeonhole PORTREVISION as well.

mail/dovecot-pigeonhole: update to 0.4.21.

Changelog 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

mail/dovecot: upgrade to 2.2.33.1.

- dovecot-lda was logging to stderr instead of to the log file.

Update dovecot to 2.2.33, and bump pigeonhole.

* doveadm director commands wait for the changes to be visible in the
  whole ring before they return. This is especially useful in testing.
* Environments listed in import_environment setting are now set or
  preserved when executing standalone commands (e.g. doveadm)

+ doveadm proxy: Support proxying logs. Previously the logs were
  visible only in the backend's logs.
+ Added %{if}, see https://wiki2.dovecot.org/Variables#Conditionals
+ Added a new notify_status plugin, which can be used to update dict
  with current status of a mailbox when it changes. See
  https://wiki2.dovecot.org/Plugins/NotifyStatus
+ Mailbox list index can be disabled for a namespace by appending
  ":LISTINDEX=" to location setting.

  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.

Update dovecot to 2.2.32, and bump pigeonhole.

* imapc: Info-level line is logged every time when successfully
  connected to the remote server. This includes local/remote IP/port,

* config: Log a warning if plugin { key=no } is used explicitly.
  v2.3 will support "no" properly in plugin settings, but for now
  any value at all for a boolean plugin setting is treated as "yes",
  even if it's written as explicit "no". This change will now warn
  that it most likely won't work as intended.

+ Various optimizations to avoid accessing files/directories when it's
  not necessary. Especially avoid accessing mail root directories when
  INDEX directories point to a different filesystem.
+ mail_location can now include ITERINDEX parameter. This tells Dovecot

Rename dovecot2/dovecot2-pigeonhole to dovecot/dovecot-pigeonhole.

It might be necessary to manually remove and reinstall the package under
the new name.
