# Production-specific values for unbound DNS resolver

# Overrides for the production environment

#
|
||||
# ARCHITECTURE NOTE:
|
||||
# Unbound provides DNSSEC validation required by Mailu (rspamd for DKIM/SPF/DMARC).
|
||||
# CoreDNS does NOT support DNSSEC, so we need Unbound as a dedicated resolver.
|
||||
#
|
||||
# Two deployment options:
|
||||
# 1. Mailu-only: Only Mailu pods use Unbound (via dnsPolicy: None)
|
||||
# - CoreDNS forwards to public DNS (8.8.8.8, 1.1.1.1)
|
||||
# - Lower resource usage, simpler architecture
|
||||
#
|
||||
# 2. Cluster-wide: CoreDNS forwards ALL external queries to Unbound
|
||||
# - All pods get DNSSEC validation
|
||||
# - Higher resource usage, single point of failure for DNS
|
||||
|
