type AlignmentMode string

const (
	AlignmentStrict  AlignmentMode = "s"
	AlignmentRelaxed               = "r"
)

type FailureOptions

type FailureOptions int

const (
	FailureAll  FailureOptions = 1 << iota // "0"
	FailureAny                             // "1"
	FailureDKIM                            // "d"

type Record

type Record struct {
	DKIMAlignment      AlignmentMode  // "adkim"
	SPFAlignment       AlignmentMode  // "aspf"
	FailureOptions     FailureOptions // "fo"
	Policy             Policy         // "p"
