SPF रिकॉर्ड चेकर
Paste a domain and we fetch its SPF record, follow every include and redirect, and tell you whether it will pass or break.
What this tool checks
- Exactly one SPF record is published
- Syntax of every mechanism and modifier
- Total DNS lookups against the limit of 10
- Void lookups (names that return nothing)
- Policy strength: -all, ~all, ?all or +all
- Nested includes and redirects, expanded as a tree
How to read the result
An SPF record fails (permerror) if it needs more than 10 DNS lookups or has a syntax error, and then mail can be rejected or sent to spam. The tool counts lookups the same way receiving servers do and shows which includes use the most.

अक्सर पूछे जाने वाले प्रश्न
What is the SPF 10 lookup limit?
Receivers stop evaluating SPF after 10 DNS-querying terms (include, a, mx, ptr, exists, redirect). Going over causes a permanent error. Read how to fix too many SPF lookups.
Can I have two SPF records?
No. Two TXT records starting with v=spf1 cause a permerror. Merge them into one.
Should I use -all or ~all?
Use ~all while you are still testing senders, and move to -all once you are sure every legitimate source is listed. See the SPF, DKIM and DMARC guide.
