SPF Result Codes - s.2.7.2 SPF defined in RFC 7208 s.2.6 - Results evaluation

Variants

Unknown

Result code not seen

NoneSpf

Either (a) syntactically valid DNS domain name was extracted from the SMTP session that could be used as the one to be authorized, or (b) no SPF records were retrieved from the DNS.

Pass

An explicit statement that the client is authorized to inject mail with the given identity.

Fail

An explicit statement that the client is not authorized to use the domain in the given identity.

SoftFail

A weak statement by the publishing ADMD that the host is probably not authorized. It has not published a stronger, more definitive policy that results in a “fail”.

Policy

RFC 8601 - Section 2.4 Indication that some local policy mechanism was applied that augments or even replaces (i.e., overrides) the result returned by the authentication mechanism. The property and value in this case identify the local policy that was applied and the result it returned.

Neutral

The ADMD has explicitly stated that it is not asserting whether the IP address is authorized.

TempError

The SPF verifier encountered a transient (generally DNS) error while performing the check. A later retry may succeed without further DNS operator action.

PermError

The domain’s published records could not be correctly interpreted. This signals an error condition that definitely requires DNS operator intervention to be resolved.

Trait Implementations

impl Clone for SpfResultCode

fn clone(&self) -> SpfResultCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpfResultCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SpfResultCode

fn default() -> SpfResultCode

Returns the “default value” for a type.

impl PartialEq for SpfResultCode

fn eq(&self, other: &SpfResultCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
