Bump PORTREVISION of mail/dovecot-fts-xapian for version change of dovecot.
Changelog:
Dovecot:
* Changed several event field names for consistency and to avoid
conflicts in parent-child event relationships:
* SMTP server command events: Renamed "name" to "cmd_name"
* Events inheriting from a mailbox: Renamed "name" to "mailbox"
* Server connection events have only "remote_ip", "remote_port",
"local_ip" and "local_port".
* Removed duplicate "client_ip", "ip" and "port".
* Mail storage events: Removed "service" field.
Use "service:<name>" category instead.
* HTTP client connection events: Renamed "host" to "dest_host" and
"port" to "dest_port"
* auth: Drop Postfix socketmap support. It hasn't been working
with recent Postfix versions for a while now.
* push-notification-lua: The "subject" field is now decoded to UTF8
instead of kept as MIME-encoded.
+ push-notification-lua: Added new "from_address", "from_display_name",
"to_address" and "to_display_name" fields. The display names are
decoded to UTF8.
+ Added various new fields to existing events.
See http://doc.dovecot.net/admin_manual/list_of_events.html
+ Add lmtp_add_received_header setting. It can be used to prevent LMTP
from adding "Received:" headers.
+ doveadm: Support SSL/STARTTLS for proxied doveadm connections based on
doveadm_ssl setting and proxy ssl/tls settings.
+ Log filters support now "service:<name>", which matches all events for
the given service. It can also be used as a category.
+ lib: Use libunwind to get abort backtraces with function names
where available.
+ lmtp: When the LMTP proxy changes the username (from passdb lookup)
add an appropriate ORCPT parameter.
- lmtp: Add lmtp_client_workarounds setting to implement workarounds for
clients that send MAIL and RCPT commands with additional spaces before
the path and for clients that omit <> brackets around the path.
See example-config/conf.d/20-lmtp.conf.
- lda/lmtp: Invalid MAIL FROM addresses were rejcted too aggressively.
Now mails from addresses with unicode characters are delivered, but
their Return-Path header will be <> instead of the given MAIL FROM
address.
- lmtp: The lmtp_hdr_delivery_address setting is ignored.
- imap: imap_command_finished event's "args" and "human_args" parameters
were always empty.
- mbox: Seeking in zlib and bzip2 compressed input streams didn't work
correctly.
- imap-hibernate: Process crashed when client got destroyed while it was
attempted to be unhibernated, and the unhibernation fails.
- *-login: Proxying may have crashed if SSL handshake to the backend
failed immediately. This was unlikely to happen in normal operation.
- *-login: If TLS handshake to upstream server failed during proxying,
login process could crash due to invalid memory access.
- *-login: v2.3 regression: Using SASL authentication without initial
response may have caused SSL connections to hang. This happened often
at least with PHP's IMAP library.
- *-login: When login processes are flooded with authentication attempts
it starts logging errors about "Authentication server sent unknown id".
This is still expected. However, it also caused the login process to
disconnect from auth server and potentially log some user's password
in the error message.
- dict-sql: SQL prepared statements were not shared between sessions.
This resulted in creating a lot of prepared statements, which was
especially inefficient when using Cassandra backend with a lot of
Cassandra nodes.
- auth: auth_request_finished event didn't have success=yes parameter
set for successful authentications.
- auth: userdb dict - Trying to list users crashed.
- submission: Service could be configured to allow anonymous
authentication mechanism and anonymous user access.
- LAYOUT=index: Corrupted dovecot.list.index caused folder creation to
panic.
- doveadm: HTTP server crashes if request target starts with double "/".
- dsync: Remote dsync started hanging if the initial doveadm
"dsync-server" command was sent in the same TCP packet as the
following dsync handshake. v2.3.8 regression.
- lib: Several "input streams" had a bug that in some rare situations
might cause it to access freed memory. This could lead to crashes or
corruption.
The only currently known effect of this is that using zlib plugin with
external mail attachments (mail_attachment_dir) could cause fetching
the mail to return a few bytes of garbage data at the beginning of the
header. Note that the mail wasn't saved corrupted, but fetching it
caused corrupted mail to be sent to the client.
- lib-storage: If a mail only has quoted content, use the quoted text
for generating message snippet (IMAP PREVIEW) instead of returning
empty snippet.
- lib-storage: When vsize header was rebuilt, newly calculated message
sizes were added to dovecot.index.cache instead of being directly
saved into vsize records in dovecot.index.
- lib: JSON generator was escaping UTF-8 characters unnecessarily.
Pigeonhole:
+ Added events for Sieve and ManageSieve, see
https://doc.dovecot.org/admin_manual/list_of_events/#pigeonhole
+ Pigeonhole: Implement the Sieve "special-use" extension described in
RFC 8579.
- duplicate: Test only compared the handles which would cause
different values to be cached as the same duplicate test. Fix to also
compare the actual hashes.
- imap_sieve_filter: IMAP FILTER Command had various bugs in error
handling. Errors may have been duplicated for each email, errors
may have been missing entirely, command tag and ERRORS/WARNINGS
parameters were swapped.
Add a note to the dovecot port about the requirement to bump the portrevision
each time dovecot is updated

release notes:
dovecot:
Changes
+ Added mail_delivery_started and mail_delivery_finished events, see
https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ dsync-replication: Don't replicate users who have "noreplicate" extra
field in userdb.
+ doveadm service status: Show total number of processes created.
+ When logging to syslog, use instance_name setting's value for the
ident. This commonly is added as a log prefix.
+ Base64 encoding/decoding code was rewritten with additional features.
It shouldn't cause any user visible changes.
- v2.3.7 regression: If a folder only receives new mails without any
other mail access, dovecot.index.log keeps growing forever and
dovecot.index keeps being rewritten for every mail delivery.
- dsync-replication may lose keywords after syncing mails restored from
another replica. This only happened if the mail only had keywords and no
system flags.
- event filters: Non-textual event fields could not be filtered using
wildcards.
- auth: Scope parameter was missing from OAuth password grant request.
- doveadm client-server communication may hang in some situations. It is
also using unnecessarily small TCP/IP packet sizes.
- doveadm who and kick did not flush protocol output correctly.
- imap: SETMETADATA with literal value would delete the metadata value
instead of updating it.
- imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
caching decisions should be updated so that newly saved mails will have
the preview cached.
- With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
permission bits in some files may have become dropped with some NFS
servers. Changed NFS flushing to now use chmod() instead of chown().
- quota: warnings did not work if quota root was noenforcing
- acl: Global ACL file ignored the last line if it didn't end with LF.
- doveadm stats dump: With JSON formatter output numbers using the
number type instead of as strings
- lmtp_proxy: Ensure that real_* variables are correctly set when using
lmtp_proxy.
- event exporter: http-post driver had hardcoded timeout and did not
support DNS lookups or TLS connections.
- auth: Fix user iteration to work with userdb passwd with glibc v2.28.
- auth: auth service can crash if auth-policy JSON response is invalid
or returned too fast.
- In some rare situations "ps" output could have shown a lot of "?"
characters after Dovecot process titles.
- When dovecot.index.pvt is empty, an unnecessary error is logged:
Error: .../dovecot.index.pvt reset, view is now inconsistent
- SMTP address encoder duplicated initial double quote character when
the localpart of an address ended in '..'. For example
"user+..@example.com" became ""user+.."@example.com in a
sieve redirect.
pigeonhole:
Changes
- Sieve may leak resources in rare cases when a redirect, vacation or
report action fails to send the message. This mainly applies when Sieve
is executed in IMAP context; i.e., for the IMAPSIEVE or FILTER=SIEVE
capabilities.
Changes
-------
* CVE-2019-11500: IMAP protocol parser does not properly handle NUL byte
when scanning data in quoted strings, leading to out of bounds heap
memory writes. Found by Nick Roessler and Rafi Rubin.
MFH: 2019Q3
Security: CVE-2019-11500
[PATCH] lib: ostream-file: Don't log any errors when setting
TCP_NODELAY
It's likely never useful to log the error, and it seems more and more
unexpected errors just keep popping up.
Obtained from: upstream git.
dovecot changelog:
* fts-solr: Removed break-imap-search parameter
+ Added more events for the new statistics, see
https://doc.dovecot.org/admin_manual/list_of_events/
+ mail-lua: Add IMAP metadata accessors, see
https://doc.dovecot.org/admin_manual/lua/
+ Add event exporters that allow exporting raw events to log files and
external systems, see
https://doc.dovecot.org/configuration_manual/event_export/
+ SNIPPET is now PREVIEW and size has been increased to 200 characters.
+ Add body option to fts_enforced. This triggers building FTS index only
on body search, and an error using FTS index fails the search rather
than reads through all the mails.
- Submission/LMTP: Fixed crash when domain argument is invalid in a
second EHLO/LHLO command.
- Copying/moving mails using Maildir format loses IMAP keywords in the
destination if the mail also has no system flags.
- mail_attachment_detection_options=add-flags-on-save caused email body
to be unnecessarily opened when FETCHing mail headers that were
already cached.
- mail attachment detection keywords not saved with maildir.
- dovecot.index.cache may have grown excessively large in some
situations. This happened especially when using autoexpunging with
lazy_expunge folders. Also with mdbox format in general the cache file
wasn't recreated as often as it should have.
- Autoexpunged mails weren't immediately deleted from the disk. Instead,
the deletion from disk happened the next time the folder was opened.
This could have caused unnecessary delays if the opening was done by
an interactive IMAP session.
- Dovecot's TCP connections sometimes add extra 40ms latency due to not
enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't
affected, but everything else was. This delay wasn't always visible -
only in some situations with some message/packet sizes.
- imapc: Fix various crash conditions
- Dovecot builds were not always reproducible.
- login-proxy: With shutdown_clients=no after config reload the
existing connections could no longer be listed or kicked with doveadm.
- "doveadm proxy kick" with -f parameter caused a crash in some
situations.
- Auth policy can cause segmentation fault crash during auth process
shutdown if all auth requests have not been finished.
- Fix various minor bugs leading into incorrect behaviour in mailbox
list index handling. These rarely caused noticeable problems.
- LDAP auth: Iteration accesses freed memory, possibly crashing
auth-worker
- local_name { .. } filter in dovecot.conf does not correctly support
multiple names and wildcards were matched incorrectly.
- replicator: dsync assert-crashes if it can't connect to remote TCP
server.
- config: Memory leak in config process when ssl_dh setting wasn't
set and there was no ssl-parameters.dat file.
This caused config process to die once in a while
with "out of memory".
pigeonhole changelog:
+ vacation: Made the subject for the automatic response message produced
by the Sieve vacation action configurable. Both the default subject
(if the script defines none) and the subject template (e.g. used to
add a subject prefix) can be configured.
- dsync: dsync-replication does not synchronize Sieve scripts.
- imap_sieve_filter: Reduce FILTER=SIEVE verbosity over IMAP connection.
- testsuite: Pigeonhole testsuite segfaulted if it was compiled with
GCC 9
Dovecot changelog:
* CVE-2019-11494: Submission-login crashed with signal 11 due to null pointer access when authentication was aborted by disconnecting.
* CVE-2019-11499: Submission-login crashed when authentication was started over TLS secured channel and invalid authentication message was sent.
* auth: Support password grant with passdb oauth2.
+ Use system default CAs for outbound TLS connections.
+ Simplify array handling with new helper macros.
+ fts_solr: Enable configuring batch_size and soft_commit features.
- lmtp/submission: Fixed various bugs in XCLIENT handling, including a hang when XCLIENT commands were sent infinitely to the remote server.
- lmtp/submission: Forwarded multi-line replies were erroneously sent as two replies to the client.
- lib-smtp: client: Message was not guaranteed to contain CRLF consistently when CHUNKING was used.
- fts_solr: Plugin was no longer compatible with Solr 7.
- Make it possible to disable certificate checking without setting ssl_client_ca_* settings.
- pop3c: SSL support was broken.
- mysql: Closing connection twice lead to crash on some systems.
- auth: Multiple oauth2 passdbs crashed auth process on deinit.
- HTTP client connection errors infrequently triggered a segmentation fault when the connection was idle and not used for a particular client instance.
Pigeonhole changelog:
+ sieve: Redirect loop prevention is sometimes ineffective. Improve existing loop detection by also recognizing the
X-Sieve-Redirected-From header in incoming messages and dropping redirect actions when it points to
the sending account. This header is already added by the redirect action, so this improvement only adds an additional use of this header.
- sieve: Prevent execution of implicit keep upon temporary failure occurring at runtime.
MFH: 2019Q2
Security: CVE-2019-11494
Security: CVE-2019-11499
* 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.
MFH: 2019Q2
Security: CVE-2019-10691
* CVE-2019-7524: Missing input buffer size validation leads into
arbitrary buffer overflow when reading fts or pop3 uidl header
from Dovecot index. Exploiting this requires direct write access to
the index files.
MFH: 2019Q1
Security: CVE-2019-7524
dovecot changelog:
+ Lua push notification driver: mail keywords and flags are provided in MessageNew and MessageAppend events.
+ submission: Implement support for plugins.
+ auth: When auth_policy_log_only=yes, only log what the policy server response would do without actually doing it.
+ auth: Always log policy server decisions with auth_verbose=yes
- v2.3.[34]: doveadm log errors: Output was missing user/session
- lda: Debug log lines could have shown slightly corrupted
- login proxy: Login processes may have crashed in various ways when login_proxy_max_disconnect_delay was set.
- imap: Fix crash with Maildir+zlib if client disconnects during APPEND
- lmtp proxy: Fix potential assert-crash
- lmtp/submission: Fix crash when SMTP client transaction times out
- submission: Split large XCLIENT commands to 512 bytes per command, so Postfix accepts them.
- submission: Fix crash when client sends invalid BURL command
- submission: relay backend: VRFY command: Avoid forwarding 500 and 502 replies back to client.
- lib-http: Fix potential assert-crash when DNS lookup fails
- lib-fts: Fix search query generation when one language ignores a token (e.g. via stopwords).
pigeonhole changelog:
+ IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which causes messages discarded by an IMAPSieve script to be expunged immediately, rather than only being marked as "\Deleted" (which is still the default behavior).
- IMAPSieve: Fix panic crash occurring when a COPY command copies
messages from a virtual mailbox where the source messages originate from more than a single real mailbox.
- imap4flags extension: Fix deleting all keywords. When the action
resulted in all keywords being removed, no changes were actually
applied.
- variables extension: Fix truncation of UTF-8 variable content. The maximum size of Sieve variables was enforced by truncating the
variable string content bluntly at the limit, but this does not
consider UTF-8 code point boundaries. This resulted in broken UTF-8 strings. This problem also surfaced for variable modifiers, such as the ":encodeurl" modifier provided by the Sieve "enotify" extension. In that case, the resulting URI escaping could also be truncated inappropriately.
- IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that modify the message, stored the message a second time, rather than replacing the originally stored unmodified message.
- Fix segmentation fault occurring when both the sieve_extprograms
plugin (for the Sieve interpreter) and the imap_filter_sieve plugin (for IMAP) are loaded at the same time. A symbol was defined by both plugins, causing a clash when both were loaded.
* CVE-2019-3814: If imap/pop3/managesieve/submission client has
trusted certificate with missing username field
(ssl_cert_username_field), under some configurations Dovecot
mistakenly trusts the username provided via authentication instead
of failing.
* ssl_cert_username_field setting was ignored with external SMTP AUTH,
because none of the MTAs (Postfix, Exim) currently send the
cert_username field. This may have allowed users with trusted
certificate to specify any username in the authentication. This bug
didn't affect Dovecot's Submission service.

Security: CVE-2019-3814
solr and tika currently use the same http client connection. Upstream
made the attached patches in response to my (ler@) bug report.
Obtained from: upstream mailing list.
dovecot change log:
* 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.
pigeonhole change log:
* Adjustments to several changes in Dovecot v2.3.4 make this Pigeonhole
release dependent on that Dovecot release; it will not compile against
older Dovecot versions. And, conversely, you need to upgrade
Pigeonhole when upgrading Dovecot to v2.3.4.
* The changes regarding the default postmaster_address in Dovecot v2.3.4
mainly apply to Pigeonhole. The new default should work for all
existing installations, thereby fixing several reported v2.3/v0.5
migration problems.
- IMAP FILTER=SIEVE capability: Fix assert crash occurring when running
UID FILTER on a Sieve script with errors.
dovecot changelog:
* doveconf hides more secrets now in the default output.
* ssl_dh setting is no longer enforced at startup. If it's not set and
non-ECC DH key exchange happens, error is logged and client is
disconnected.
+ Added log_debug=<filter> setting.
+ Added log_core_filter=<log filter> setting.
+ quota-clone: Write to dict asynchronously
+ --enable-hardening attempts to use retpoline Spectre 2 mitigations
+ lmtp proxy: Support source_ip passdb extra field.
+ doveadm stats dump: Support more fields and output stddev by default.
+ push-notification: Add SSL support for OX backend.
- NUL bytes in mail headers can cause truncated replies when fetched.
- director: Conflicting host up/down state changes may in some rare
situations ended up in a loop of two directors constantly overwriting
each others' changes.
- director: Fix hang/crash when multiple doveadm commands are being
handled concurrently.
- director: Fix assert-crash if doveadm disconnects too early
- virtual plugin: Some searches used 100% CPU for many seconds
- dsync assert-crashed with acl plugin in some situations.
- mail_attachment_detection_options=add-flags-on-save assert-crashed
with some specific Sieve scripts.
- Mail snippet generation crashed with mails containing invalid
Content-Type:multipart header.
- Log prefix ordering was different for some log lines.
- quota: With noenforcing option current quota usage wasn't updated.
- auth: Kerberos authentication against Samba assert-crashed.
- stats clients were unnecessarily chatty with the stats server.
- imapc: Fixed various assert-crashes when reconnecting to server.
- lmtp, submission: Fix potential crash if client disconnects while
handling a command.
- quota: Fixed compiling with glibc-2.26 / support libtirpc.
- fts-solr: Empty search values resulted in 400 Bad Request errors
- fts-solr: default_ns parameter couldn't be used
- submission server crashed if relay server returned over 7 lines in
a reply (e.g. to EHLO)
pigeonhole changelog:
- Fix assertion panic occurring when managesieve service fails to open
INBOX while saving a Sieve script. This was caused by a lack of
cleanup after failure.
- Fix specific messages causing an assert panic with actions that
compose a reply (e.g. vacation). With some rather weird input from the
original message, the header folding algorithm (as used for composing
the References header for the reply) got confused, causing the panic.
- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing.
After finishing reading the Sieve script, the command parsing
sometimes didn't continue with the search arguments. This is a time-
critical bug that likely only occurs when the Sieve script is sent in
the next TCP frame.
Add a patch to close stderr in src/master/main.c, should fix PR 228003.

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
dovecot changelog:
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.
pigeonhole changelog:
Changelog v0.5.2:
+ Implement plugin for the a vendor-defined IMAP capability called
"FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering
in IMAP. More information can be found in
doc/plugins/imap_filter_sieve.txt.
- The Sieve address test caused an assertion panic for invalid addresses
with UTF-8 codepoints in the localpart. Fixed by properly detecting
invalid addresses with UTF-8 codepoints in the localpart and skipping
these like other invalid addresses while iterating addresses for the
address test.
- Make the length of the subject header for the vacation response
configurable and enforce the limit in UTF-8 codepoints rather than
bytes. The subject header for a vacation response was statically
truncated to 256 bytes, which is too limited for multi-byte UTF-8
characters.
- Sieve editheader extension: Fix assertion panic occurring when it is
used to manipulate a message header with a very large header field.
- Properly abort execution of the sieve_discard script upon error.
Before, the LDA Sieve plugin attempted to execute the sieve_discard
script when an error occurs. This can lead to the message being lost.
- Fix the interaction between quota and the sieve_discard script. When
quota was used together with a sieve_discard script, the message
delivery did not bounce when the quota was exceeded.
This brings back Dovecot 2.2.35 to the tree because there is an issue
with version 2.3.1 and replication in some scenarios [1].
Keep this version until this problem gets fixed upstream.
