Managed SPF (Delegation)
DMARC Busta uses SPF delegation to manage your SPF record without you needing to manually edit DNS.
How It Works
- Your root SPF record includes:
include:_spf.yourdomain.com - The
_spfsubdomain is a CNAME pointing to DMARC Busta - When you approve sources, DMARC Busta updates the managed record
- 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
