pkgsrc changes:
---------------
* change COMMENT to make pkglint happy (inspired by http://www.postfix.org/)
* update PLIST using make print-PLIST (missing @pkgdir)
upstream changes:
-----------------
20181125
Cleanup: dict_file_to_xxx() takes a list of file names
separated by CHARS_COMMA_SP. Shoe-horned into the existing
API, make it nicer when there is time. File: util/dict_file.c.
20181127
Cleanup: encapsulated clumsy 'read into VSTRING' code with
easier-to-use vstream_fread_buf() and vstream_fread_app()
primitives. Files: global/memcache_proto.c, global/record.c,
global/smtp_stream.c, global/smtp_stream.h, global/uxtext.c,
global/xtext.c, milter/milter8.c, util/dict_file.c,
util/hex_quote.c, util/netstring.c, util/vstream.c,
util/vstream.h. Verified with "make tests".
Cleanup: simplified the smtp_fread() API (introduced for
BDAT support), and changed the name to smtp_fread_buf().
Files: global/smtp_stream.c, smtpd/smtpd.c. Verified with
~megabyte BDAT commands.
Cleanup: simplified a tlsproxy-internal API. File:
tlsproxy/tlsproxy.c.
20181128
Initial support for key/certificate chain files that will
replace the proliferation of separate parameters for
RSA/DSA/ECC/etc. key and certificate files. Viktor
Dukhovni.
20181201
Cleanup: replaced the remaining unsafe VSTRING_AT_OFFSET()
calls with safe vstring_set_payload_size() calls, in code
that directly writes into VSTRING. Files: tls/tls_session.c,
tlsmgr/tlsmgr.c, util/casefold.c, util/vstring.c, util/vstring.h,
xsasl/xsasl_cyrus_client.c.
Cleanup: postscreen_command_time_limit did not need to be
a 'raw' parameter. This makes "postconf -x" behavior more
consistent. Files: global/mail_params.h, postscreen/postscreen.c.
Documentation: added text that the following parameter
values are not subject to Postfix parameter $name expansion:
default_rbl_reply, command_execution_directory, luser_relay,
smtpd_reject_footer. These have their own documented $name
substitution mechanism. File: proto/postconf.proto.
20181202
Bugfix: posttls-finger reported an error for UNIX-domain
connections, even if they did not fail. Found by Coverity.
File: posttls-finger/posttls-finger.c.
20181208
Documentation: add even more redundancy to the rate-delay
description. File: proto/postconf.proto.
20181210
Cleanup: code deduplication. File: util/dict_file.c.
20181226
Cleanup: code deduplication and better encapsulation with
PSC_DEL_CLIENT_STATE() and PSC_DEL_SERVER_STATE() macros.
Files: postscreen/postscreen.h, postscreen/postscreen_state.c.
Documentation: POSTSCREEN_README did not describe the
postscreen_post_queue_limit, and attributed the wrong reject
message to the postscreen_pre_queue_limit. Problem reported
by Michael Orlitzky. File: proto/POSTSCREEN_README.html.
(20181226-nonprod) Compatibility: removed support for OpenSSL
1.0.1 (not supported since December 31, 2016) and earlier
releases. This eliminated a large number of #ifdefs with
bitrot workarounds. Viktor Dukhovni. Files: global/mail_params.h,
posttls-finger/posttls-finger.c, tls/tls.h, tls/tls_certkey.c,
tls/tls_client.c, tls/tls_dane.c, tls/tls_dh.c, tls/tls_misc.c,
tls/tls_proxy_client_scan.c, tls/tls_rsa.c, tls/tls_server.c,
tls/tls_session.c.
(20181226-nonprod) Use the OpenSSL 1.0.2 and later API for
setting ECDHE curves. Viktor Dukhovni. Files: tls/tls.h,
tls/tls_client.c, tls/tls_dh.c.
(20181226-nonprod) Documentation update for TLS support.
Viktor Dukhovni. Files: mantools/postlink, proto/TLS_README.html,
proto/postconf.proto, src/sendmail/sendmail.c, src/smtpd/smtpd.c.
20181229
Explicit maps_file_find() and dict_file_lookup() methods
that decode base64 content. Decoding content is not built
into the dict->lookup() method, because that would complicate
the implementation of map nesting (inline, thash), map
composition (pipemap, unionmap), and map proxying. For
consistency, decoding base64 file content is also not built
into the maps_find() method. Files: util/dict.h.
util/dict_file.c, global/maps.[hc], postmap/postmap.c.
20190106
Documentation: documented the SRC_RHS_IS_FILE flag in
dict_open.c, and updated the -F description in the postmap
manpage. Files: util/dict_open.c, postmap/postmap.c.
(20190106-nonprod) Feature: support for files that combine
multiple (key, certificate, trust chain) instances in one
file, to avoid separate files for RSA, DSA, Elliptic Curve,
and so on. Viktor Dukhovni. Files: .indent.pro,
global/mail_params.h, posttls-finger/posttls-finger.c,

tls/tls_proxy_client_scan.c, tls/tls_proxy_server_print.c,
tls/tls_proxy_server_scan.c, tls/tls_server.c, tlsproxy/tlsproxy.c.
(20190106-nonprod) Create a second, no-key no-cert, SSL_CTX
for use with SNI. Viktor Dukhovni. Files: src/tls/tls.h,
src/tls/tls_client.c, src/tls/tls_misc.c, src/tls/tls_server.c.
(20190106-nonprod) Server-side SNI support. Viktor Dukhovni.
Files: src/global/mail_params.h, src/smtp/smtp.c,
src/smtpd/smtpd.c, src/tls/tls.h, src/tls/tls_certkey.c,
src/tls/tls_misc.c, src/tlsproxy/tlsproxy.c,
(20190106-nonprod) Configurable client-side SNI signal.
Viktor Dukhovni. Files: global/mail_params.h,
posttls-finger/posttls-finger.c, smtp/lmtp_params.c,
smtp/smtp.c, smtp/smtp.h, smtp/smtp_params.c, smtp/smtp_proto.c,
smtp/smtp_tls_policy.c, tls/tls.h, tls/tls_client.c,
tls/tls_proxy.h, tls/tls_proxy_client_print.c,
tls/tls_proxy_client_scan.c.
20190121
Logging: support for internal logging file, without using
syslog (it uses the new postlogd daemon instead). This
solves a usability problem for MacOS, may help getting
around systemd, and solves 99% of the problem for logging
to stdout in a container (hopefully we have 100% soon).
Enable by setting, for example, "maillog_file =
/var/log/postfix.log"). This works fine for daemons, and
with some limitations for non-daemon programs. See
RELEASE_NOTES for more details. Files: conf/master.cf,
conf/post-install, conf/postfix-files, conf/postfix-script,
mantools/postlink, proto/master, proto/postconf.proto,

Cleanup: cert/key/chain loading, plus unit tests to exercise
non-error and error cases. Viktor Dukhovni. Files: tls/*.pem,
tls*.pem.ref, tls/tls_certkey.c.
20190126
Safety: Postfix programs will log to either syslog or postlog
but not both; and postlogd forwards postlog logging to
syslog, when a configuration change removes the maillog_file
pathname, but some programs still use the old configuration.
Files: util/msg_syslog.[hc], util/msg_logger.c,
global/maillog_client.c, postlogd/postlogd.c,
Bugfix (introduced: Postfix 20110109, Postfix 2.10): watchdog
pipe file descriptor leak. This pipe provides one source
of liveness, data from this pipe is discarded, and therefore
this does not enable privilege escalation or DOS. File:
util/watchdog.c.
Feature: stdout logging support; requires "postfix start-fg"
and "maillog_file = /dev/stdout". Files: master/master.c,
conf/postfix-script.
20190127
Safety: when maillog_file is specified, 'postfix check' now
requires that the postlog service is enabled in master.cf.
Otherwise 'postfix start' etc. will log a fatal error. File:
conf/postfix-script.
Documentation: added policy_context example. File:
proto/SMTPD_POLICY_README.html.
20190128
Testing: run libtls tests under Valgrind. File tls/Makefile.in.
20190129
Safety: require that $maillog_file matches one of the
pathname prefixes specified in $maillog_file_prefixes. The
maillog file is created by root, and the prefixes limit the
damage from a single configuration error. Files:
global/mail_params.[hc], global/maillog_client.c.
20191201
Feature: "postfix logrotate" command with configurable
compression program and datestamp filename suffix. File:
conf/postfix-script.
20190202
Cleanup: log a warning when the client sends a malformed
SNI; log an info message when the client sends a valid SNI
that does not match the SNI lookup tables; update the
FORWARD_SECRECY_README logging examples. Viktor Dukhovni.
Files: proto/FORWARD_SECRECY_README.html, tls/tls.h,
tls/tls_client.c, tls/tls_misc.c.
20190208
Debugging: the master(8) daemon now logs a warning if a
master.cf entry is defined multiple times. File:
src/master/master_conf.c.
20190209
Debugging: tlsproxy(8) now logs more details about unexpected
configuration differences between the Postfix SMTP client
and the tlsproxy(8) daemon.
20190210
Documentation: Postfix 3.4.0 RELEASE NOTES.
Documentation: added BDAT_README.
Documentation: global TLS settings. Files: mantools/postlink,
smtp/smtp.c, tlsproxy/tlsproxy.c.
20190211
Cleanup: removed obsolete parameters: tls_dane_digest_agility,
tls_dane_trust_anchor_digest_enable; removed openssl_path
parameter from configuration difference checks in tlsproxy.
Files: global/mail_params.h, tls/tls_misc.c,
tls/tls_proxy_client_misc.c, tls/tls_proxy_client_print.c,
tls/tls_proxy_client_scan.c, tls/tls_proxy.h.
20190212
Cleanup: missing #ifdef USE_TLS. Files: smtp/smtp_session.c,
posttls-finger/posttls-finger.c.
20190217
Cleanup: when the master daemon runs with PID=1 (init mode),
reap orhpan processes from non-Postfix code running in the
same container, instead of terminating with a panic. File:
master/master_spawn.c.
20190218
Bugfix: tlsproxy did not enable DANE-style PKI because
libtls seems to have to accreted multiple init functions
instead of reusing the tls_client_init() and tls_client_start()
API. And some functions that do initialization don't even
have init in their name! Problem report by Andreas Schulze.
Viktor Dukhovni. Files: tls/tls_misc.c, tlsproxy/tlsproxy.c.
Workaround: Postfix libtls makes DANE-specific changes to
the shared SSL_CTX. To avoid false sharing, tlsproxy needs
to label the SSL_CTX cache with DANE bits until we can
remove the code that modifies SSL_CTX. File: tlsproxy/tlsproxy.c.
Cleanup: Postfix libtls changed the shared SSL_CTX to
override ciphers. instead of changing the SSL handle. To
avoid false sharing in tlsproxy, the changes are now made
to the SSL handle. Viktor Dukhovni. Files: tls/tls.h,
tls/tls_client.c, tls/tls_misc.c, tls/tls_server.c.
20190219
Bugfix: in the Postfix SMTP client, TLS wrappermode was not
tested in tlsproxy mode. It needed some setup for buffering
and timeouts. Problem report by Andreas Schulze. File:
smtp/smtp_proto.c.
20190304
Bugfix: a reversed test broke TLS configurations that specify
the same filename for a private key and certificate. Reported
by Mike Kazantsev. Fix by Viktor Dukhovni. Wietse fixed the
test. Files: tls/tls_certkey.c, tls/Makefile.in.
20190310
Bitrot: LINUX5s support, after some sanity checks with a
rawhide prerelease version. Files: makedefs, util/sys_defs.h.
Bugfix (introduced: 20181226): broken DANE trust anchor
file support, caused by left-over debris from the 20181226
TLS library overhaul. By intrigeri. File: tls/tls_dane.c.
Bugfix (introduced: Postfix-1.0.1): null pointer read, while
logging a warning after a corrupted bounce log file. File:
global/bounce_log.c.
Bugfix (introduced: Postfix-2.9.0): null pointer read, while
logging a warning after a postscreen_command_filter read
error. File: postscreen/postscreen_smtpd.c. global/bounce_log.c
20190312
Bugfix (introduced: Postfix 2.2): reject_multi_recipient_bounce
has been producing false rejects starting with the Postfix
2.2 smtpd_end_of_data_restrictons, and for the same reasons,
does the same with the Postfix 3.4 BDAT command. The latter
was reported by Andreas Schulze. File: smtpd/smtpd_check.c.
20190319
With message_size_limit=0 (which is NOT DOCUMENTED), BDAT
chunks were always rejected as too large. File: smtpd/smtpd.c
20190328
Bugfix (introduced: Postfix 3.0): LMTP connections over
UNIX-domain sockets were cached but not reused, due to a
cache lookup key mismatch. Therefore, idle cached connections
could exhaust LMTP server resources, resulting in two-second
pauses between email deliveries. This problem was investigated
by Juliana Rodrigueiro. File: smtp/smtp_connect.c.
20190331
Documentation: tlsext_padding is not a tls_ssl_options
feature. File: proto/postconf.proto.
20190401
Portability: added "#undef sun" to util/unix_dgram_connect.c.
20190403
Bugfix (introduced: Postfix 2.3): a censoring filter broke
multiline Milter responses for header/body events. Problem
report by Andreas Thienemann. Files: util/printable.c,
util/stringops.h, smtpd/smtpd.c
Bugfix (introduced: Postfix 3.3): "smtp_mx_address_limit =
0" no longer meant 'unlimited'. Problem report by Luc Pardon.
File: smtp/smtp_addr.c.
20190615
Documentation: updated the BUGS section in the smtp(8) manpage
about TLS connection reuse. File: smtp/smtp.c.
Workaround for implementations that hang Postfix while
shutting down a TLS session, until Postfix times out. With
"tls_fast_shutdown_enable = yes" (the default), Postfix no
longer waits for the TLS peer to respond to a TLS 'close'
request. This is recommended with TLSv1.0 and later. Files:
global/mail_params.h, tls/tls_session.c, and documentation.
20190621
Bugfix (introduced: Postfix 3.0): the code to reset Postfix
SMTP server command counts was not called after a HaProxy
handshake failure, causing stale numbers to be reported.
The command counts are now reset in the function that reports
the counts. File: smtpd/smtpd.c.
pkgsrc changes:
---------------
* Remove -DHAS_EAI since it does not appear anywhere
* Add pkg-config to USE_TOOLS since patch-ai introduces it
* Bump revision since binaries are now linked to icui18n
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.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
[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).
Postfix stable release 3.3.0 is available. This release ends support
for legacy release Postfix 2.11.
The main changes are:
* Dual license: in addition to the historical IBM Public License
1.0, Postfix is now also distributed with the more recent Eclipse
Public License 2.0. Recipients can choose to take the software
under the license of their choice. Those who are more comfortable
with the IPL can continue with that license.
* The postconf command now warns about unknown parameter names
in a Postfix database configuration file. As with other unknown
parameter names, these warnings can help to find typos early.
* Container support: Postfix 3.3 will run in the foreground with
"postfix start-fg". This requires that Postfix multi-instance
support is disabled (the default). To collect Postfix syslog
information on the container's host, mount the host's /dev/log
socket into the container, for example with "docker run -v
/dev/log:/dev/log ...other options...", and specify a distinct
Postfix syslog_name setting in the container (for example with
"postconf syslog_name=the-name-here").
* Milter support: applications can now send RET and ENVID parameters
in SMFIR_CHGFROM (change envelope sender) requests.
* Postfix-generated From: headers with 'full name' information
are now formatted as "From: name <address>" by default. Specify
"header_from_format = obsolete" to get the earlier form "From:
address (name)".
* Interoperability: when Postfix IPv6 and IPv4 support are both
enabled, the Postfix SMTP client will now relax MX preferences
and attempt to schedule similar numbers of IPv4 and IPv6
addresses. This works around mail delivery problems when a
destination announces lots of primary MX addresses on IPv6, but
is reachable only over IPv4 (or vice versa). The new behavior
is controlled with the smtp_balance_mx_inet_protocols parameter.
* Compatibility safety net: with compatibility_level < 1, the
Postfix SMTP server now warns for mail that would be blocked
by the Postfix 2.10 smtpd_relay_restrictions feature, without
blocking that mail. There still is a steady trickle of sites
that upgrade from an earlier Postfix version.
Update mail/postfix to 3.2.5.
[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.

This announcement concerns fixes for problems that were introduced
with Postfix 3.2. Older releases are unaffected.
Fixed in Postfix 3.2 and later:
* Extension propagation was broken with "recipient_delimiter = .".
This change reverts a change that was trying to be too clever.
* The postqueue command would abort with a panic message after it
experienced an output write error while listing the mail queue.
This change restores a write error check that was lost with the
Postfix 3.2 rewrite of the vbuf_print formatter.
* Restored sanity checks for dynamically-specified width and precision
in format strings (%*, %.*, and %*.*). These checks were lost with
the Postfix 3.2 rewrite of the vbuf_print formatter.
pkgsrc change: Add support for NetBSD 8.
This announcement (June 13, 2017) includes changes that were released
with an earlier update (June 10, 2017). The announcement was postponed
to avoid confusion due to repeated notification.
Fixed in all supported releases:
* Security: Berkeley DB versions 2 and later try to read settings
from a file DB_CONFIG in the current directory. This undocumented
feature may introduce undisclosed vulnerabilities resulting in
privilege escalation with Postfix set-gid programs (postdrop,
postqueue) before they chdir to the Postfix queue directory,
and with the postmap and postalias commands depending on whether
the user's current directory is writable by other users. This
fix does not change Postfix behavior for Berkeley DB versions
< 3, but it does reduce postmap and postalias 'create' performance
with Berkeley DB versions 3.0 .. 4.6.
Fixed in Postfix 3.2 and later:
* The SMTP server receive_override_options were not restored at
the end of an SMTP session, after the options were modified by
an smtpd_milter_maps setting of "DISABLE". Milter support
remained disabled for the life time of the smtpd process.
* After the Postfix 3.2 address/domain table lookup overhaul, the
check_sender_access and check_recipient_access features ignored
a non-default parent_domain_matches_subdomains setting.
- Elliptic curve negotiation with OpenSSL >= 1.0.2. This changes the
default smtpd_tls_eecdh_grade setting to "auto", and introduces a
new parameter tls_eecdh_auto_curves with the names of curves that may
be negotiated.
- Stored-procedure support for MySQL databases.
- Cidr: table support for if/endif and negation (by prepending ! to a
pattern), just like regexp: and pcre: tables. See the cidr_table(5)
manpage for details.
- The postmap command and the inline: and texthash: maps now support
spaces in left-hand field of lookup table source text. Use double
quotes (") around a left-hand field that contains spaces, and use
backslash (\) to protect quotes in a left-hand field.
- Support for per-client Milter configuration (smtpd_milter_maps) that
overrides the main.cf smtpd_milters setting, and that has the same
syntax. A lookup result of "DISABLE" turns off Milter support for that
client.
- The local SMTP server IP address and port are available in the
policy delegation protocol (attribute names: server_address,
server_port), in the Milter protocol (macro names: {daemon_addr},
{daemon_port}), and in the XCLIENT protocol (attribute names:
DESTADDR, DESTPORT).
- For safety reasons, the Postfix sendmail -C option must specify an
authorized directory: the default configuration directory, a
directory that is listed in the default main.cf file with
alternate_config_directories or multi_instance_directories, otherwise
the command must be invoked with root privileges. This mitigates a
recurring "jail break" problem with the PHP mail() function.
- "PASS" and "STRIP" actions in header/body_checks. "STRIP" is similar
to "IGNORE" but also logs the action, and "PASS" disables header,
body, and Milter inspection for the remainder of the message content.
- The collate.pl script by Viktor Dukhovni for grouping Postfix
logfile records into "sessions" based on queue ID and process ID
information, in the auxiliary/collate directory of the Postfix source
tree.
Disabled or removed behavior:
- SMTPUTF8 support: Postfix 3.2 disables the 'transitional'
compatibility between the IDNA2003 and IDNA2008 standards for
internationalized domain names (domain names beyond the limits of
US-ASCII). This makes Postfix behavior consistent with contemporary
web browsers.
- Postfix 3.2 removes tentative features that were implemented before
the DANE spec was finalized: support for certificate usage
PKIX-EE(1), the ability to disable digest agility, and the ability to
disable support for "TLSA 2 [01] [12]" records that specify the digest

Postfix stable release 3.1.4 is available, as well as legacy releases
3.0.8 and 2.11.9. There will be no further updates for Postfix 2.10.
Fixed with Postfix 3.1.4, 3.0.8, and 2.11.9:
* The postscreen daemon did not merge the client test status
information for concurrent sessions from the same IP address.
Thus, after one session recorded its successful tests in the
postscreen cache, a concurrent session from that same IP address
that passed fewer tests could later "wipe out" some of that
progress in the postscreen cache. The fix has proven itself for
five months in the development release, and should be safe to
use in the stable releases.
* The Postfix SMTP server falsely rejected a sender address when
validating a sender address with "smtpd_reject_unlisted_recipient
= yes" or with "reject_unlisted_sender". Cause: the address
validation code did not query sender_canonical_maps.
* The virtual delivery agent did not detect failure to skip to
the end of a mailbox file, so that mail would be delivered to
the beginning of the file. This could happen when a mailbox
file was already larger than the virtual mailbox size limit.
* The postsuper command logged an incorrect rename operation count
after creating a missing directory.
Fixed with Postfix 3.1.4 and 3.0.8:
* The Postfix SMTP server falsely rejected mail when a sender-dependent
"error" transport was configured. Cause: the SMTP server address
validation code was not updated when the
sender_dependent_default_transport_maps feature was introduced.
The fix has proven itself for six months in the development
release, and should be safe to use in the stable releases.
Unfortunately, Postfix 2.11 is too different to benefit from
the same fix.
* The Postfix SMTP server falsely rejected an SMTPUTF8 sender
address, when "smtpd_delay_reject = no".
Fixed with Postfix 3.1.4:
* The "postfix tls deploy-server-cert" command used the wrong
certificate and key file. This was caused by a cut-and-paste
error in the postfix-tls-script file.
Fixed with Postfix 3.1.3 and 3.0.7:
* The Postfix SMTP server did not reset a previous session's
failed/total command counts before rejecting a client that
exceeds request or concurrency rates. This resulted in incorrect
failed/total command counts being logged at the end of the
rejected session.
* The unionmap multi-table interface did not propagate table
lookup errors, resulting in false "user unknown" responses.
* The documentation was updated with a workaround for false "not
found" errors with MySQL map queries that contain UTF8-encoded
text. The workaround is to specify "option_group = client" in
Postfix MySQL configuration files. This will be the default
setting with Postfix 3.2 and later.
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.
Very surprisingly, postfix's build hard-codes shared library behavior
in a giant case statement not only per OS but per version, essentially
open-coding libtool while not being complete. This commit copies the
netbsd-6 flags to netbsd-5, as a minimal change during the freeze to
let this build on netbsd-5 (where it then works fine).
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
With all supported Postfix releases, the default settings have been
updated so that they no longer enable export-grade ciphers, and no
longer enable the SSLv2 and SSLv3 protocols. These ciphers and
protocols have little if any legitimate use today, and have instead
become a vehicle for downgrade attacks. There are no other code
changes.
Postfix documentation has been updated to reflect the new default
settings and their rationale; the RELEASE_NOTES give suggestions
for how to enable the old ciphers and protocols if your infrastructure
requires them.
Finally, abandoning deprecated ciphers and protocols does not really
improve TLS security without measures to better authenticate remote
servers. Secure DNS and TLSA are steps in that direction.
Fixed in Postfix 3.0 and 2.11:
* Preparation for OpenSSL 1.2 API changes.
Fixed in all supported releases:
* The sender_dependent_relayhost_maps feature ignored the relayhost
setting in the case of a DUNNO lookup result. It would use the
recipient domain instead.
