- Support for long, non-repeating, queue IDs (queue file names). The
main benefit of non-repeating names is simpler logfile analysis. See
the description of "enable_long_queue_ids" in postconf(5) for
details.
- Memcache client support, and support to share postscreen(8) and
verify(8) caches via the proxymap server. Details about memcache
support are in memcache_table(5) and MEMCACHE_README.
- Gradual degradation: if a database is unavailable (can't open, most
read or write errors) a Postfix daemon will log a warning and
continue providing the services that don't depend on that table,
instead of immediately terminating with a fatal error. To terminate
immediately when a database file can't be opened, specify
"daemon_table_open_error_is_fatal = yes".
- Revised postconf(1) command. It warns about unused parameter
name=value settings in main.cf or master.cf (likely mistakes),
understands "dynamic" parameter names such as names that depend on
the name of a master.cf entry (finally, "postconf -n" shows all
parameter settings), and it can display main.cf and master.cf in a
more user-friendly format (postconf -nf, postconf -Mf).
- Read/write deadline support in the SMTP client and server to defend
against application-level DOS attacks that very slowly write or read
data one byte at a time.
nor why it uses &p0 as a magic constant (rather than NULL).
Re-instate the definition of p0, but enable the 'fake' definition
of 'struct proc' if the relevant part of sys/proc.h seems to have
been #if'ed away.
Should fix the build.
it and the OS has enabled XGETBV for application use.
It might need to also check XCR0[2] (having executed XGETBV) to check that
the kernel actually supports saving the YMM registers, but I suspect the
kernel might defer setting that until the first fault.

Fixes toolchain/45673
- The postscreen_access_list feature failed to ignore case in the first
character of a command (e.g., permit, reject, etc.). Reported by Francis
Picabia. (This fix is incorrectly listed in the HISTORY files of earlier
releases, and will be removed with a future patch.)
- Strip the datalink suffix (e.g., %eth0) from IPv6 addresses returned by
the system getaddrinfo() routine. Such suffixes break the default
mynetworks value, the Postfix SMTP server's reverse/forward DNS
name/address mapping check, and possibly more.
- To eliminate the possibility of collisions with connection cache lookup
keys, the Postfix LDAP client now computes those lookup keys by joining
the number-valued connection properties with ASCII null, just like it
already did with the string-valued connection properties.
- There was a memory leak during one-time TLS library initialization
(introduced with Postfix 2.5). Reported by Coverity.
- There was a memory leak in the unused oqmgr(8) program (introduced with
Postfix 2.3). Reported by Coverity.
