many users.
lmtp: Session IDs were duplicated/confusing with multiple RCPT TOs
when lmtp_rcpt_check_quota=yes
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.
Made the retention period for redirect duplicate identifiers
configurable. 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
managesieve-login: Fixed handling of AUTHENTICATE command. A second
authenticate command would be parsed wrong.

not work perfectly.
mdbox: "Inconsistency in map index" wasn't fixed automatically
dict-ldap: %variable values used in the LDAP filter weren't escaped.

childrens' indexes.

that were down.
Various fixes to handling mailbox listing. Especially related to
handling nonexistent autocreated/autosubscribed mailboxes and ACLs.
Global ACL file was parsed as if it was local ACL file. This caused
some of the ACL rule interactions to not work exactly as intended.
Using mail_sort_max_read_count may have caused very high CPU usage.
Message address parsing could have crashed on invalid input.
imapc_features=fetch-headers wasn't always working correctly and

Some internal error messages may have contained garbage in v2.2.29
mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys
are used. Otherwise the copied mails can't be opened.
dict-sql: Merging multiple UPDATEs to a single statement wasn't
actually working.
pigeonhole updated to 0.4.18
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".
fts-tika: Fixed crash when parsing attachment without
Content-Disposition header. Broken by 2.2.28.
trash plugin was broken in 2.2.28
auth: When passdb/userdb lookups were done via auth-workers, too much
data was added to auth cache. This could have resulted in wrong
replies when using multiple passdbs/userdbs.
auth: passdb { skip & mechanisms } were ignored for the first passdb
oauth2: Various fixes, including fixes to crashes
dsync: Large Sieve scripts (or other large metadata) weren't always
synced.

doveadm-server: Fix leaks and other problems when process is reused
for multiple requests (service_count != 1)
sdbox: Fix assert-crash on mailbox create race

was used. especially %{storage_id} was broken.
imapsieve plugin: Fixed assert failure occurring when used with virtual
mailboxes.
doveadm sieve plugin: Fixed crash when setting Sieve script via attribute's
string value.
authentication was aborted/failed without a username set.
- director: If two users had different tags but the same hash,
the users may have been redirected to the wrong tag's hosts.

"Missing middle file seq=.." to be logged and index rebuild.
This happened more easily with IMAP hibernation enabled.

inside lib-index, which runs index fsck.
- quota: Don't skip quota checks when moving mails between different
quota roots.
- search: Multiple sequence sets or UID sets in search parameters
weren't handled correctly. They were incorrectly merged together.
- master process's listener socket was leaked to all child processes.
This might have allowed untrusted processes to capture and prevent
"doveadm service stop" comands from working.
- login proxy: Fixed crash when outgoing SSL connections were hanging.
- auth: userdb fields weren't passed to auth-workers, so %{userdb:*}
from previous userdbs didn't work there.

mailbox state.

part of the disconnection reason.
- MIME body parser didn't handle properly when a child MIME part's --boundary
had the same prefix as the parent.
- pigeonhole updated to 0.4.14
- extprograms plugin: Fixed epoll() panic caused by closing the output
FD before the output stream.

- director: Fixed a situation where directors keep re-sending
different states to each others and never becoming synced.
- director: Fixed assert-crash related to a slow "user killed" reply
- Fixed assert-crash related to istream-concat, which could have
been triggered at least by a Sieve script.

used in default_fields, override_fields or LDAP pass/user_attrs.
userdb result_* were also ignored when user was found from cache.

caught actual hangs or otherwise unwanted behavior towards IMAP
clients.

configuration options.
- Sieve mime extension: Fixed the header :mime :anychild test to work properly
outside a foreverypart loop.

empty or broken text part.
- Fixed assert failure in handling of body parts that are converted to text.

+ sieve body extension: Properly implemented the `:text' body
transform. It now extracts text for HTML message parts.

didn't support NOTIFY.
- imap: After SETMETADATA was used, various commands (especially FETCH)
could have started hanging when their output was large.

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

(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.

automatically fixed in v2.2.3.

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.
https://bugzilla.redhat.com/show_bug.cgi?id=956194
