dovecot2: updated to 2.3.5.2

v2.3.5.2
* CVE-2019-10691: Trying to login with 8bit username containing
  invalid UTF8 input causes auth process to crash if auth policy is
  enabled. This could be used rather easily to cause a DoS. Similar
  crash also happens during mail delivery when using invalid UTF8 in
  From or Subject header when OX push notification driver is used.

Log message:
dovecot2: updated to 2.3.4

2.3.4:
 * The default postmaster_address is now "postmaster@<user domain or
   server hostname>". If username contains the @domain part, that's
   used. If not, then the server's hostname is used.
 * "doveadm stats dump" now returns two decimals for the \ 
"avg" field.

 + Added push notification driver that uses a Lua script
 + Added new SQL, DNS and connection events.
   See https://wiki2.dovecot.org/Events
 + Added "doveadm mailbox cache purge" command.
 + Added events API support for Lua scripts
 + doveadm force-resync -f parameter performs "index fsck" while opening
   the index. This may be useful to fix some types of broken index files.
   This may become the default behavior in a later version.
 - director: Kicking a user crashes if login process is very slow
 - pop3_no_flag_updates=no: Don't expunge DELEted and RETRed messages
   unless QUIT is sent.
 - auth: Fix crypt() segfault with glibc-2.28+
 - imap: Running UID FILTER script with errors assert-crashes
 - dsync, pop3-migration: POP3 UIDLs weren't added to
   dovecot.index.cache while mails were saved.
 - dict clients may have been using 100% CPU while waiting for dict
   server to finish commands.
 - doveadm user: Fixed user listing via HTTP API
 - All levels of Cassandra log messages were logged as Dovecot errors.
 - http/smtp client may have crashed after SSL handshake
 - Lua auth converted strings that looked like numbers into numbers.

Log message:

Recursive revbump from textproc/icu-62.1

Log message:
dovecot2: updated to 2.3.2.1

v2.3.2 still had a few unexpected bugs:
- SSL/TLS servers may have crashed during client disconnection
- lmtp: With lmtp_rcpt_check_quota=yes mail deliveries may have
  sometimes assert-crashed.
- v2.3.2: "make check" may have crashed with 32bit systems

v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as \ 
well as a bunch of other fixes (mainly for v2.3-only bugs). Binary packages are \ 
already in https://repo.dovecot.org/
* old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while
  opening /proc/self/io. This may still cause security problems if the
  process is ptrace()d at the same time. Instead, open it while still
  running as root.
+ doveadm: Added mailbox cache decision&remove commands. See
  doveadm-mailbox(1) man page for details.
+ doveadm: Added rebuild attachments command for rebuilding
  $HasAttachment or $HasNoAttachment flags for matching mails. See
  doveadm-rebuild(1) man page for details.
+ cassandra: Use fallback_consistency on more types of errors
+ lmtp proxy: Support outgoing SSL/TLS connections
+ lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings.
+ submission: Add support for rawlog_dir
+ submission: Add submission_client_workarounds setting.
+ lua auth: Add password_verify() function and additional fields in
  auth request.
- doveadm-server: TCP connections are hanging when there is a lot of
  network output. This especially caused hangs in dsync-replication.
- Using multiple type=shared mdbox namespaces crashed
- mail_fsync setting was ignored. It was always set to "optimized".
- lua auth: Fix potential crash at deinit
- SSL/TLS servers may have crashed if client disconnected during
  handshake.
- SSL/TLS servers: Don't send extraneous certificates to client when
  alt certs are used.
- lda, lmtp: Return-Path header without '<' may have assert-crashed.
- lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash
- lda: -f parameter didn't allow empty/null/domainless address
- lmtp, submission: Message size limit was hardcoded to 40 MB.
  Exceeding it caused the connection to get dropped during transfer.
- lmtp: Fix potential crash when delivery fails at DATA stage
- lmtp: login_greeting setting was ignored
- Fix to work with OpenSSL v1.0.2f
- systemd unit restrictions were too strict by default
- Fix potential crashes when a lot of log output was produced
- SMTP client may have assert-crashed when sending mail
- IMAP COMPRESS: Send "end of compression" marker when disconnecting.
- cassandra: Fix consistency=quorum to work
- dsync: Lock file generation failed if home directory didn't exist
- Snippet generation for HTML mails didn't ignore &entities inside
  blockquotes, producing strange looking snippets.
- imapc: Fix assert-crash if getting disconnected and after
  reconnection all mails in the selected mailbox are gone.
- pop3c: Handle unexpected server disconnections without assert-crash
- fts: Fixes to indexing mails via virtual mailboxes.
- fts: If mails contained NUL characters, the text around it wasn't
  indexed.
- Obsolete dovecot.index.cache offsets were sometimes used. Trying to
  fetch a field that was just added to cache file may not have always
  found it.

Log message:
revbump after icu update

Log message:
Update mail/dovecot2* to 2.3.0.

Some of the larger changes:

* Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3
* Logging rewrite started: Logging is now based on hierarchical events.
  This makes it possible to do various things, like: 1) giving
  consistent log prefixes, 2) enabling debug logging with finer
  granularity, 3) provide logs in more machine readable formats
  (e.g. json). Everything isn't finished yet, especially a lot of the
  old logging code still needs to be translated to the new way.
* Statistics rewrite started: Stats are now based on (log) events.
  It's possible to gather statistics about any event that is logged.
  See http://wiki2.dovecot.org/Statistics for details
* ssl_dh setting replaces the old generated ssl-parameters.dat
* IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error
  instead of [UNKNOWNCTE]
* Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by
  default due to potential security reasons (found by cPanel Security
  Team).
+ Added support for SMTP submission proxy server, which includes
  support for BURL and CHUNKING extension.
+ LMTP rewrite. Supports now CHUNKING extension and mixing of
  local/proxy recipients.
+ auth: Support libsodium to add support for ARGON2I and ARGON2ID
  password schemes.
+ auth: Support BLF-CRYPT password scheme in all platforms
+ auth: Added LUA scripting support for passdb/userdb.
  See https://wiki2.dovecot.org/AuthDatabase/Lua
- Input streams are more reliable now when there are errors or when
  the maximum buffer size is reached. Previously in some situations
  this could have caused Dovecot to try to read already freed memory.
- Output streams weren't previously handling failures when writing a
  trailer at the end of the stream. This mainly affected encrypt and
  zlib compress ostreams, which could have silently written truncated
  files if the last write happened to fail (which shouldn't normally
  have ever happened).
- virtual plugin: Fixed panic when fetching mails from virtual
  mailboxes with IMAP BINARY extension.
- doveadm-server: Fix potential hangs with SSL connections
- doveadm proxy: Reading commands' output from v2.2.33+ servers could
  have caused the output to be corrupted or caused a crash.
- Many other smaller fixes
