Log Message:
mail/postfix: update to 3.7.2

3.7.0 (2022-02-07)

  * Support to inline the content of small cidr:, pcre:, and regexp:
    tables in Postfix parameter values. An example is the new
    smtpd_forbidden_commands default value, "CONNECT GET POST
    regexp:{{/^[^A-Z]/ Thrash}}", to quickly drop connections from
    clients that send garbage.

  * To make the maillog_file feature more useful, including stdout
    logging from a container, the postlog(1) command is now set-gid
    postdrop, so that unprivileged programs can use it to write
    logging through the postlogd(8) daemon. This required hardening
    the postlog(1) command against privilege escalation attacks.

  * Support for library APIs: OpenSSL 3.0.0, PCRE2, Berkeley DB 18.

  * Postfix programs now randomize the initial state of in-memory
    hash tables, to defend against hash collision attacks involving
    a large number of attacker-chosen lookup keys. Presently, the
    only known opportunity for such attacks involves remote SMTP
    client IPv6 addresses in the anvil(8) service, and requires
    making hundreds of short-lived connections per second while
    cycling through thousands of different client IP addresses.

  * Updated defense against remote clients or servers that 'trickle'
    SMTP or LMTP traffic. This replaces the old per-record deadlines
    with per-request deadlines and minimum data rates.

  * Many typofixes by raf and Wietse.

3.7.1 (2022-04-18)

  * (problem introduced: Postfix 2.7) The milter_header_checks maps
    are now opened before the cleanup(8) server enters the chroot
    jail. Problem reported by Jesper Dybdal.

  * In an internal client module, "host or service not found" was
    a fatal error, causing the milter_default_action setting to be
    ignored. It is now a non-fatal error, just like a failure to
    connect. Problem reported by Christian Degenkolb.

  * The proxy_read_maps default value was missing up to 27 parameter
    names. The corresponding lookup tables were not automatically
    authorized for use with the proxymap(8) service. The parameter
    names were ending in _checks, _reply_footer, _reply_filter,
    _command_filter, and _delivery_status_filter.

  * (problem introduced: Postfix 3.0) With dynamic map loading
    enabled, an attempt to create a map with "postmap regexp:path"
    would result in a bogus error message "Is the postfix-regexp
    package installed?" instead of "unsupported map type for this
    operation". This happened with all non-dynamic map types (static,
    cidr, etc.) that have no 'bulk create' support. Problem reported
    by Greg Klanderman.

  * In PCRE_README, "pcre2 --libs" should be "pcre2 \ 
--libs8". Problem
    reported by Carlos Velasco.

  * Documented in the postlogd(8) daemon manpage that the Postfix
    >= 3.7 postlog(1) command can run with setgid permissions.

3.7.2 (2022-04-28)

This reverts an overly complex change in the postscreen SMTP engine
(made during Postfix 3.7 development), and replaces it with much
simpler code. The bad change was crashing postscreen on some systems
after receiving malformed input (for example, a TLS "hello" message).
