allocation in the sieve command implementations.

multiple recipients and fts_autoindex=yes.
- zlib plugin: Fixed copying causing cache corruption when zlib_save
wasn't set, but the source message was compressed.

- lmtp: quota_full_tempfail=yes was ignored with
lmtp_rcpt_check_quota=yes
- mdbox: Rebuilding could have caused message's reference count to
overflow the 16bit number in some situations, causing problems when
trying to expunge the duplicates.

- Various virtual plugin fixes
- Various fixes and optimizations to dsync, imapc and pop3-migration

director ring sockets, causing it to break in existing installations.

alt storage as well.
director ring sockets, causing it to break in existing installations.
- sdbox: When copying a mail in alt storage, place the destination to
alt storage as well.
- auth: Don't crash if master user login is attempted without
any configured master=yes passdbs
- Parsing UTF-8 text for mails could have caused broken results
sometimes if buffering was split in the middle of a UTF-8 character.
This affected at least searching messages.
- String sanitization for some logged output wasn't done properly:
UTF-8 text could have been truncated wrongly or the truncation may
not have happened at all.
- fts-lucene: Lookups from virtual mailbox consisting of over 32
physical mailboxes could have caused crashes.
- fixed several race conditions with dovecot.index.cache handling that
may have caused unnecessary "cache is corrupted" errors.
- auth: If auth client listed userdb and disconnected before finishing,
the auth worker process got stuck
- imap-login, pop3-login: Fixed potential crashes when client
disconnected unexpectedly.
- imap proxy: The connection was hanging in some usage patterns.

(When [NOMODSEQ] is returned by SELECT, mainly with in-memory
indexes.)
- imap: Various fixes to METADATA support.
- stats plugin: Processes that only temporarily dropped privileges
(e.g. indexer-worker) may have been logging errors about not being
able to open /proc/self/io.
"--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't
trigger this, because messages must end with an "LF.". A user could
trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
sent to it.
- replicator: Database wasn't being exported to disk every 15 minutes
as it should have. Instead it was being imported, causing "doveadm
replicator remove" commands to not work very well.
- master process was doing a hostname.domain lookup for each created
process, which may have caused a lot of unnecessary DNS lookups.
- dsync: Syncing over 100 messages at once caused problems in some
situations, causing messages to get new UIDs.
- fts-solr: Different Solr hosts for different users didn't work.

- mdbox: Corrupted index header still wasn't automatically fixed.
- dsync: Various fixes to work better with imapc and pop3c storages.
- ldap: sasl_bind=yes caused crashes, because Dovecot's lib-sasl
symbols conflicted with Cyrus SASL library.
- imap/pop3 proxy: Master user logins were broken in v2.2.3
- sdbox/mdbox: A corrupted index header with wrong size was never
automatically fixed in v2.2.3.
- mbox: Fixed assert-crashes related to locking.
- IMAP: If subject contained only whitespace, Dovecot returned an
ENVELOPE reply with a huge literal value, effectively causing the
IMAP client to wait for more data forever.
- IMAP: Various URLAUTH fixes.
- imapc: Various bugfixes and improvements
- pop3c: Various fixes to make it work in dsync (without imapc)

but the remote login timed out.
Some of the documentation in %docdir (wiki/Migration*.txt) uses perl as
an interpreter, which causes rpmbuild to autogenerate deps on perl.
Filter this out as it's not needed for the main dovecot functionality.

- Mailbox list indexes weren't using proper file permissions based
on the root directory.

some users.
- Various fixes to mailbox_list_index=yes
