SPF Record Syntax
Note: This page serves as an introduction and quick overview of SPF mechanism syntax. For the complete and definitive picture, please see thespecification.Domains define zero or more mechanisms. Mechanisms can be used to describe the set of hosts which are designated outbound mailers for the domain. all | ip4 | ip6 | a | mx | ptr | exists |includeDomains may also define modifiers. Each modifier can appear only once.redirect | expMechanismsMechanisms can be prefixed with one of four qualifiers: "+" | Pass |
"-" | Fail |
"~" | SoftFail |
"?" |Neutral |
If a mechanism results in a hit, its qualifier value is used. The default qualifier is "+", i.e. "Pass". For example:"v=spf1 -all""v=spf1 a -all""v=spf1 a mx -all""v=spf1 +a +mx-all"Mechanisms are evaluated in order. If no mechanism or modifier matches, the default result is "Neutral".If a domain has no SPF record at all, the result is "None". If a domain has a temporary error during DNSprocessing, you get the result "TempError" (called "error" in earlier drafts). If some kind of syntax or evaluation error occurs (eg. the domain specifies an unrecognized mechanism) the result is"PermError" (formerly "unknown").Evaluation of an SPF record can return any of these results: Result | Explanation | Intended action |
Pass | The SPF record designates the host to be allowed to send |accept |
Fail | The SPF record has designated the host as NOT being allowed to send | reject |
SoftFail | The SPF record has designated the host as NOT being allowed to send but is in transition |accept but mark |
Neutral | The SPF record specifies explicitly that nothing can be said about validity | accept |
None | The domain does not have an SPF record or the SPF record does not evaluate to aresult | accept |
PermError | A permanent error has occured (eg. badly formatted SPF record) | unspecified |
TempError | A transient error has occured | accept or reject |
The "all" mechanism...
