# Default values for unbound DNS resolver
# This is a YAML-formatted file.
# Declare variables to be passed into your templates.
#
# PURPOSE: Provides DNSSEC validation for Mailu email server
# CoreDNS does NOT support DNSSEC, so Unbound fills this gap.
# Mailu's rspamd requires DNSSEC for DKIM/SPF/DMARC validation.
