How DMARC Busta manages your SPF record

Managed SPF (Delegation)

DMARC Busta uses SPF delegation to manage your SPF record without you needing to manually edit DNS.

How It Works

  1. Your root SPF record includes DMARC Busta's managed SPF via an include: directive
  2. The managed SPF TXT record is hosted on DMARC Busta's nameserver
  3. When you approve sources, DMARC Busta updates the managed record
  4. Changes propagate automatically without touching your DNS

Benefits

  • No DNS editing - Changes happen automatically
  • Stay under limits - Optimized to avoid the 10-lookup limit
  • IP consolidation - Individual IPs converted to includes
  • Audit trail - All changes are logged
