SPF Syntax Validator
Enter the SPF policy to be validated, e.g. v=spf1 +mx -all.
What Is This?
This validator helps to verify the proper syntax of an SPF policy. The validator displays detailed information about syntax errors and warns you if something looks suspicious.
Which SPF Versions Are Supported?
The only supported version is SPF Classic (the draft version published in May 2004). Get this SPF draft version here.
Does "Passed" Mean That My SPF Policy Is OK?
No. The validator does not check a number of things that can be only validated during evaluation, e.g. redirections or macros that extend to domain arguments. You may also want to test with our SPF Checker.
Which SPF Library Is Used By This Validator?
The library behind this validator is our own SPF library developed for ORF.
