dovecot2: updated to 2.3.19


+ 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
+ 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
+ doveadm deduplicate: Performance is improved significantly.
+ imapc: COPY commands were sent one mail at a time to the remote IMAP
  server. Now the copying is buffered, so multiple mails can be copied
  with a single COPY command.
+ lib-lua: Add a Lua interface to Dovecot's HTTP client library. See
  https://doc.dovecot.org/admin_manual/lua/ for more information.
- auth: Cache lookup would use incorrect cache key after username change.
- auth: Improve handling unexpected LDAP connection errors/hangs.
  Try to fix up these cases by reconnecting to the LDAP server and
  aborting LDAP requests earlier.
- auth: Process crashed if userdb iteration was attempted while auth-workers
  were already full handling auth requests.
- auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary
  introspection requests.
- dict: Timeouts may have been leaked at deinit.
- director: Ring may have become unstable if a backend's tag was changed.
  It could also have caused director process to crash.
- doveadm kick: Numeric parameter was treated as IP address.
- doveadm: Proxying can panic when flushing print output. Fixes
  Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
  (ioloop == current_ioloop).
- doveadm sync: BROKENCHAR was wrongly changed to '_' character when
  migrating mailboxes. This was set by default to %, so any mailbox
  names containing % characters were modified to "_25".
- imapc: Copying or moving mails with doveadm to an imapc mailbox could
  have produced "Error: Syncing mailbox '[...]' failed" Errors. The
  operation itself succeeded but attempting to sync the destination
  mailbox failed.
- imapc: Prevent index log synchronization errors when two or more imapc
  sessions are adding messages to the same mailbox index files, i.e.
  INDEX=MEMORY is not used.
- indexer: Process was slowly leaking memory for each indexing request.
- lib-fts: fts header filters caused binary content to be sent to the
  indexer with non-default configuration.
- doveadm-server: Process could hang in some situations when printing
  output to TCP client, e.g. when printing doveadm sync state.
- lib-index: dovecot.index.log files were often read and parsed entirely,
  rather than only the parts that were actually necessary. This mainly
  increased CPU usage.
- lmtp-proxy: Session ID forwarding would cause same session IDs being
  used when delivering same mail to multiple backends.
- log: Log prefix update may have been lost if log process was busy.
  This could have caused log prefixes to be empty or in some cases
  reused between sessions, i.e. log lines could have been logged for the
  wrong user/session.
- mail_crypt: Plugin crashes if it's loaded only for some users. Fixes
  Panic: Module context mail_crypt_user_module missing.
- mail_crypt: When LMTP was delivering mails to both recipients with mail
  encryption enabled and not enabled, the non-encrypted recipients may
  have gotten mails encrypted anyway. This happened when the first
  recipient was encrypted (mail_crypt_save_version=2) and the 2nd
  recipient was not encrypted (mail_crypt_save_version=0).
- pop3: Session would crash if empty line was sent.
- stats: HTTP server leaked memory.
- submission-login: Long credentials, such as OAUTH2 tokens, were refused
  during SASL interactive due to submission server applying line length
- submission-login: When proxying to remote host, authentication was not
  using interactive SASL when logging in using long credentials such as
  OAUTH2 tokens. This caused authentication to fail due to line length
  constraints in SMTP protocol.
- submission: Terminating the client connection with QUIT command after
  mail transaction is started with MAIL command and before it is
  finished with DATA/BDAT can cause a segfault crash.
- virtual: doveadm search queries with mailbox-guid as the only parameter
  crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records):
  assertion failed: (result != 0)

dovecot2: updated to 2.3.18


	* 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 \ 
	  and ":Rn" (recipient) counters after the session ID prefix.
	+ Events now have "reason_code" field, which can provide a list of
	  reasons why the event is happening. See
	+ New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/
	+ fts: Added fts_header_excludes and fts_header_includes settings to
	  specify which headers to index. See
	  for configuration details.
	+ fts: Initialize the textcat language detection library only once per
	  process. This can reduce CPU usage if fts_languages setting has multiple
	  languages listed and service indexer-worker { service_count } isn't 1.
	  Only applies when using libfts.
	+ lib-storage: Reduced CPU usage significantly for some operations that
	  accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...)
	+ lib: DOVECOT_PREREQ() - Add micro version which enables compiling
	  external plugins against different versions of Dovecot.
	+ lmtp: Added new lmtp_verbose_replies setting that makes errors sent to
	  the LMTP client much more verbose with details about why exactly
	  backend proxy connections or commands are failing.
	+ submission: Support implicit SASL EXTERNAL with
	  submission_client_workarounds=implicit-auth-external. This allows
	  automatically logging in when SSL client certificate is present.
	- *-login: Statistics were disabled if stats process connection was lost.
	- auth: Authentication master user login fails with SCRAM-* SASL mechanisms.
	- auth: With auth_cache_verify_password_with_worker=yes, passdb extra
	  fields in the auth cache got lost.
	- doveadm: Fixed crash if zlib_save_level setting was specified,
	  but zlib_save was unset. v2.3.15 regression.
	- doveadm: Proxying can panic when flushing print output. v2.3.17
	  regression. Fixes:
	  Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
	  (ioloop == current_ioloop)
	- doveadm: stats add --group-by parameter didn't work.
	- fts: Using email-address fts tokenizer could result in excessive memory
	  usage with garbage email input. This could cause the indexer-worker
	  processes to fail due to reaching the VSZ memory size limit.
	  Only applies when using libfts.
	- imap: A SEARCH command timing out while fts returns indexes may timeout
	  returning "NO [SERVERBUG]", while it should return "NO \ 
[INUSE]" instead.
	- imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending
	  LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for
	  folders that are not subscribed when they have a child folder that is
	  subscribed as mandated by IMAP RFCs.
	- imapc: Mailbox vsize calculation crashed with
	  Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing):
	  assertion failed: (mails_left > 0)
	- indexer: If indexer-worker crashes, the request it was processing gets
	  stuck in the indexer process. This stops indexing for the folder until
	  indexer process is restarted. v2.3.14 regression.
	- indexer: Process was slowly leaking memory for each indexing request.
	- lib-event: Unnamed events were wrongly filtered out for event/metric
	  filters like "event=abc OR something_independent_of_event_name".
	- lib-index: 64-bit big endian CPUs handle last_used field in
	  dovecot.index.cache wrong.
	- lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing.
	  If there is no error available, log it as an error instead of crashing.
	  The previous fix for this in v2.3.11 was incomplete. Fixes
	  Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real):
	  assertion failed: (errno != 0)
	- lmtp: Out-of-memory issues can happen when proxying large messages to
	  LMTP backend servers that accept the message data too slow.
	- master: HAProxy header parsing has read buffer overflow if provided
	  header size is invalid. This happens only if inet_listener
	  { haproxy=yes } is configured and only if the remote IP address is in
	- old_stats: Plugin kept increasing memory usage, which became
	  noticeable with long-running imap sessions.
	- stats: Dynamically adding same metric multiple times causes multiple stats.
	- submission-login: Authentication does not accept OAUTH2 token (or
	  other very long credentials) because it considers the line to be too long.
	- submission-login: Process can crash if HELO is pipelined with an
	  invalid domain.
	- submission-proxy: Don't use SASL-IR if it would make the AUTH command
	  line longer than 512 bytes.
	- submission: Service would crash if relay server authentication failed.
	- virtual: FTS search in a virtual folder could crash if there are
	  duplicate mailbox GUIDs. This mainly happened when user had both INBOX
	  and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes
	  Panic: file hash.c: line 252 (hash_table_insert_node):
	  assertion failed: (opcode == HASH_TABLE_OP_UPDATE)
	- virtual: If mailbox opening fails, the backend mailbox is leaked and
	  process crashes when client disconnects. Fixes
	  Panic: file mail-user.c: line 232 (mail_user_deinit):
	  assertion failed: ((*user)->refcount == 1)
	- virtual: Searching headers in virtual folders didn't always use
	  full-text search indexes, if fts_enforced=no or body.
