What are the limits of SPF Record Analyzer?
Static analysis only: does not evaluate a sender or query included domains. Counts DNS-triggering terms on every supplied include/redirect path; missing references and macros make the total incomplete. Cycles, +all, unreachable mechanisms, duplicate modifiers and syntax issues are reported. a/mx/ptr can involve additional DNS work; no deliverability verdict. 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.
