What are the limits of DMARC Record Studio?
Produces a DNS TXT value and reviews supplied tags using RFC 7489 semantics. Does not publish DNS or prove SPF/DKIM alignment. External report destinations require separate authorization by the receiving domain; report addresses may expose aggregate metadata. Forensic reports are not enabled by the builder. Text input: 5 MB total. XML external entities and includes are disabled. No automatic local storage. Reports summarize the selected result; CSV/JSON retain complete records.
