patches/packages/glibc-zoneinfo-2023d-noarch-1_slack15.0.txz: Upgraded.
This package provides the latest timezone updates.
patches/packages/postfix-3.6.13-x86_64-1_slack15.0.txz: Upgraded.
Security: this release adds support to defend against an email spoofing
attack (SMTP smuggling) on recipients at a Postfix server. Sites
concerned about SMTP smuggling attacks should enable this feature on
Internet-facing Postfix servers. For compatibility with non-standard
clients, Postfix by default excludes clients in mynetworks from this
countermeasure.
The recommended settings are:
# Optionally disconnect remote SMTP clients that send bare newlines,
# but allow local clients with non-standard SMTP implementations
# such as netcat, fax machines, or load balancer health checks.
#
smtpd_forbid_bare_newline = yes
smtpd_forbid_bare_newline_exclusions = $mynetworks
The smtpd_forbid_bare_newline feature is disabled by default.
