Roy Cohen focused on improving email governance and operational visibility in the hmcts/azure-public-dns repository by addressing a critical DMARC configuration issue. He updated all environment configuration files to route DMARC reports and failure notifications to the correct distribution list, replacing the outdated recipient with DMARC_DL@hmcts.net. This change, implemented in a single, well-documented commit, enhanced reporting reliability and reduced the risk of misrouted notifications. Roy applied his expertise in DNS configuration, DevOps practices, and YAML to ensure consistent updates across multiple environments. The work demonstrated careful configuration management and strengthened the security posture of the DNS infrastructure.
