- update to 3.8.0
* Support to look up DNS SRV records in the Postfix SMTP/LMTP
client, Based on code by Tomas Korbar (Red Hat). For example,
with "use_srv_lookup = submission" and "relayhost =
example.com:submission", the Postfix SMTP client will look up
DNS SRV records for _submission._tcp.example.com, and will relay
email through the hosts and ports that are specified with those
records.
* TLS obsolescence: Postfix now treats the "export" and "low"
cipher grade settings as "medium". The "export" and "low" grades
are no longer supported in OpenSSL 1.1.1, the minimum version
required in Postfix 3.6.0 and later. Also, Postfix default
settings now exclude deprecated or unused ciphers (SEED, IDEA,
3DES, RC2, RC4, RC5), digest (MD5), key exchange algorithms
(DH, ECDH), and public key algorithm (DSS).
* Attack resistance: the Postfix SMTP server can now aggregate
smtpd_client_*_rate and smtpd_client_*_count statistics by
network block instead of by IP address, to raise the bar against
a memory exhaustion attack in the anvil(8) server; Postfix TLS
support unconditionally disables TLS renegotiation in the middle
of an SMTP connection, to avoid a CPU exhaustion attack.
* The PostgreSQL client encoding is now configurable with the
"encoding" Postfix configuration file attribute. The default
is "UTF8". Previously the encoding was hard-coded as "LATIN1",
which is not useful in the context of SMTP.
* The postconf command now warns for #comment in or after a Postfix
parameter value. Postfix programs do not support #comment after
other text, and treat that as input.

- update to 3.7.4
* Workaround: with OpenSSL 3 and later always turn on
SSL_OP_IGNORE_UNEXPECTED_EOF, to avoid warning messages and missed
opportunities for TLS session reuse. This is safe because the SMTP protocol
implements application-level framing, and is therefore not affected by TLS
truncation attacks.
* Workaround: OpenSSL 3.x EVP_get_digestbyname() can return lazily-bound
handles for digest implementations. In sufficiently hostile configurations,
Postfix could mistakenly believe that a digest algorithm is available, and
fail when it is not. A similar workaround may be needed for
EVP_get_cipherbyname().
* Bugfix (bug introduced in Postfix 2.11): the checkok() macro in
tls/tls_fprint.c evaluated its argument unconditionally; it should evaluate
the argument only if there was no prior error.
* Bugfix (bug introduced in Postfix 2.8): postscreen died with a segmentation
violation when postscreen_dnsbl_threshold < 1. It should reject such input
with a fatal error instead.
* Bitrot: fixes for linker warnings from newer Darwin (MacOS) versions.
* Portability: Linux 6 support.
* Added missing documentation that cidr:, pcre: and regexp: tables support
inline specification only in Postfix 3.7 and later.
* Rebased postfix-linux45.patch

- Update to 3.4.4
o Incompatible changes
- The Postfix SMTP server announces CHUNKING (BDAT
command) by default. In the unlikely case that this breaks some
important remote SMTP client, disable the feature as follows:
/etc/postfix/main.cf:
# The logging alternative:
smtpd_discard_ehlo_keywords = chunking
# The non-logging alternative:
smtpd_discard_ehlo_keywords = chunking, silent_discard
- This introduces a new master.cf service 'postlog'
with type 'unix-dgram' that is used by the new postlogd(8) daemon.
Before backing out to an older Postfix version, edit the master.cf
file and remove the postlog entry.
- Postfix 3.4 drops support for OpenSSL 1.0.1
- To avoid performance loss under load, the
tlsproxy(8) daemon now requires a zero process limit in master.cf
(this setting is provided with the default master.cf file). By
default, a tlsproxy(8) process will retire after several hours.
- To set the tlsproxy process limit to zero:
postconf -F tlsproxy/unix/process_limit=0
postfix reload
o Major changes
- Postfix SMTP server support for RFC 3030 CHUNKING
(the BDAT command) without BINARYMIME, in both smtpd(8) and
postscreen(8). This has no effect on Milters, smtpd_mumble_restrictions,
and smtpd_proxy_filter. See BDAT_README for more.
- Support for logging to file or stdout, instead of using syslog.
- Logging to file solves a usability problem for MacOS, and
