How to identify TXT record conflicts?
Query all TXT records:
- dig TXT yourdomain.com
- Lists all TXT records at that name.
Common conflicts:
- Multiple SPF records (only one allowed, causes permerror)
- Multiple DMARC records at _dmarc
- Duplicate verification strings
How they occur:
- Adding new SPF instead of editing existing
- Multiple people managing DNS without coordination
- Leftover records from old services
Resolution:
- Merge multiple SPF into one record
- Remove obsolete records
- Document which records serve which purpose
Conflicting documents cause processing failure. Consolidate and clarify the registry.
