Update postfix and related pacakges to 3.5.3.
Quote freom release announce.
Postfix 3.5.3, 3.4.13:
* TLS handshake failure in the Postfix SMTP server during SNI
processing, after the server-side TLS engine sent a TLSv1.3
HelloRetryRequest (HRR) to a remote SMTP client. Reported by
J??n M??t??, fixed by Viktor Dukhovni.
Postfix versions 3.5.3, 3.4.13, 3.3.11, 3.2.16:
* The command "postfix tls deploy-server-cert" did not handle a
missing optional argument. This bug was introduced in Postfix
3.1.
Update postfix to 3.5.1.
3.5.0 (2020-03-16)
Postfix stable release 3.5.0 is available. Support has ended for
legacy release Postfix 3.1.
The main changes are below. See the RELEASE_NOTES file for further details.
* Support for the haproxy v2 protocol. The Postfix implementation
supports TCP over IPv4 and IPv6, as well as non-proxied
connections; the latter are typically used for heartbeat tests.
* Support to force-expire email messages. This introduces new
postsuper(1) command-line options to request expiration, and
additional information in mailq(1) or postqueue(1) output.
* The Postfix SMTP and LMTP client support a list of nexthop
destinations separated by comma or whitespace. These destinations
will be tried in the specified order. Examples:
/etc/postfix/main.cf:
relayhost = foo.example, bar.example
default_transport = smtp:foo.example, bar.example
Incompatible changes:
* Logging: Postfix daemon processes now log the from= and to=
addresses in external (quoted) form in non-debug logging (info,
warning, etc.). This means that when an address localpart
contains spaces or other special characters, the localpart will
be quoted, for example:
from=<"name with spaces"@example.com>
Specify "info_log_address_format = internal" for backwards compatibility.
* Postfix now normalizes IP addresses received with XCLIENT,
XFORWARD, or with the HaProxy protocol, for consistency with
direct connections to Postfix. This may change the appearance
of logging, and the way that check_client_access will match
subnets of an IPv6 address.
3.5.1 (2020-04-20)
Postfix versions 3.5.1, 3.4.11, 3.3.9, 3.2.14:
* Bitrot workaround for broken builds after an incompatible change
in GCC 10.
* Bitrot workaround for broken DANE/DNSSEC support after an
incompatible change in GLIBC 2.31. This change avoids the need
for new options in /etc/resolv.conf.
This announcement concerns fixes for problems that were introduced
with Postfix 3.0 and later. This is the final update for Postfix
3.0.
Fixed in Postfix 3.3 and later:
* When the master daemon runs with PID=1 (init mode), it will now
reap child processes from non-Postfix code running in the same
container, instead of terminating with a panic. Reported by
Tamas Gerczei.
Fixed in Postfix 3.0 and later:
* With smtputf8_enable=yes, table lookups could casefold the
search string when searching a lookup table that does not use
fixed-string keys (regexp, pcre, tcp, etc.).
* With the posttls-finger test program, connections to unix-domain
servers always resulted in "Failed to establish session" even
after a connection was established. Reported by Jaroslav Skarva.
Changes for all supported stable releases:
* Support for OpenSSL 1.1.1, and support for TLSv1.3-specific
features.
- Updated Postfix TLS documentation examples for TLSv1.3. See
FORWARD_SECRECY_README.
- New TLSv1.3-specific attributes in Postfix logging and in
Postfix "Received:" message headers: key exchange, server
signature, client signature.
- New option to selectively disable TLSv1.3 in *_tls_protocols
settings.
- New server-side support to avoid issuing multiple session
tickets.
- New support to allow OpenSSL >= 1.1.0 run-time micro version
bumps without logging Postfix warnings about library version
mismatches.
Fixed in all stable releases:
* Bugfix: smtpd_discard_ehlo_keywords could not disable "SMTPUTF8",
because some lookup table was using "EHLO_MASK_SMTPUTF8" instead.
* Bugfix: minor memory leak in DANE support when minting issuer
certs. This affects a tiny minority of use cases.
Fixed in Postfix 3.3.2:
* Bugfix: the Postfix build did not abort if the m4 command was
not installed, resulting in a broken postconf command.
[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.3.1.html]
Fixed in Postfix 3.3:
* Postfix did not support running as a PID=1 process, which
complicated Postfix deployment in containers. The "postfix
start-fg" command will now run the Postfix master daemon as a
PID=1 process if possible. Thanks for inputs from Andreas
Schulze, Eray Aslan, and Viktor Dukhovni.
* Segfault in the postconf(1) command after it could not open a
Postfix database configuration file due to a file permission
error (dereferencing a null pointer). Reported by Andreas
Hasenack, fixed by Viktor Dukhovni.
Fixed in Postfix 3.3, 3.2, 3.1, 3.0:
* The luser_relay feature became a black hole, when the luser_relay
parameter was set to a non-existent local address (i.e. mail
disappeared silently). Reported by J?rgen Thomsen.
* Missing error propagation in the tlsproxy(8) daemon could result
in a segfault after TLS handshake error (dereferencing a
0xffff...ffff pointer). This daemon handles the TLS protocol
when a non-whitelisted client sends a STARTTLS command to
postscreen(8).
[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.2.4.html]
This announcement concerns fixes for problems that were introduced
with Postfix 3.0 and later. Older supported releases are unaffected.
Fixed in Postfix 3.1 and later:
* DANE interoperability. Postfix builds with OpenSSL 1.0.0 or
1.0.1 failed to send email to some sites with "TLSA 2 X X" DNS
records associated with an intermediate CA certificate. Problem
report and initial fix by Erwan Legrand.
Fixed in Postfix 3.0 and later:
* Missing dynamicmaps support in the Postfix sendmail command.
This broke authorized_submit_users settings that use a
dynamically-loaded map type. Problem reported by Ulrich Zehl.
3.1.0
The main changes in no particular order are:
* "postfix tls" command to simplify setup of opportunistic TLS,
and to simplify SMTP server key/certificate management.
* Positive and negative DNS reply TTL support in postscreen(8).
* SASL AUTH rate limit in the Postfix SMTP server.
* A safety limit on the number of address verify requests.
* JSON-format Postfix queue listing.
* Destination-independent delivery rate delay
For details, see the RELEASE_NOTES file.
3.1.1
Fixed in all supported releases:
* The Milter "replace sender" (SMFIR_CHGFROM) request lost an
address that was added with sender_bcc_maps, resulting in a
"rcpt count mismatch" warning. Reported by Joerg Backschues.
This defect was introduced with Postfix 2.6.
* The "bad filetype" example in the header_checks(5) manpage
falsely rejected Content- headers with ``name="example";
x-apple-part-url="example.com"''. Reported by Cedric Knight.
This defect was introduced with Postfix 2.6.
3.1.2
Fixed with Postfix 3.1.2:
* Changes to make Postfix build with OpenSSL 1.1.0.
Fixed with Postfix 3.1.2 and 3.0.6:
* The makedefs script ignored readme_directory=pathname overrides.
Fix by Todd C. Olson.
* The tls_session_ticket_cipher documentation says that the default
cipher for TLS session tickets is aes-256-cbc, but the implemented
default was aes-128-cbc. Note that TLS session ticket keys are
rotated after 1/2 hour, to limit the impact of attacks on session
ticket keys.
Database and regexp map functionality is now split into separate packages:
- postfix-cdb
- postfix-ldap
- postfix-lmdb
- postfix-mysql
- postfix-pcre
- postfix-pgsql
- postfix-sqlite
Upstream changelog follows.
Postfix 3.0.2
-------------
No delta against 2.11.6.
Postfix 3.0.1
-------------
- Build error when compiling the Postfix SMTP server with SASL support
but no TLS support.
- The DNS "resource record to text" converter, used for xxx_dns_reply_filter
pattern matching, appended a '.' to TXT record resource values.
- The postscreen(8) manpage specified an incorrect Postfix version number
for the postscreen_dnsbl_timeout parameter.
- The postfix-install script expanded macros in parameter values when
trying to detect parameter overrides, causing unnecessary main.cf updates
during "postfix start" etc.
- Some low-level cleanup of UTF-8 string handling with no visible change
in behavior (besides better performance).
Postfix 3.0.0
-------------
- SMTPUTF8 support for internationalized domain names and address
localparts as defined in RFC 6530 and related documents.
- Support for Postfix dynamically-linked libraries and database plugins.
- An OPT-IN safety net for the selective adoption of new Postfix default
settings. If you do nothing, the old Postfix default settings *should*
remain in effect (complain to your downstream maintainer if that is not
the case).
- Support for operations on multiple lookup tables. The
pipemap:{map1,map2...} database type implements a pipeline of lookup
tables where the result from one lookup table becomes a query for
the next table; the unionmap:{map1,map2,...} database type sends the
