Implements RFC4408 Sender Policy Framework (SPF) check_host() validation.
yarn add spf-check
The stable API returns a string with one of the possible returns.
const spf = require('spf-check');
const result = spf(ip, domain, sender);
if (result === spf.Pass) {
// Yay!
}This module also exports SPF and SPFResult classes to allow inspect the
result and read the expected message.
const validator = new spf.SPF('mediamonks.com', '[email protected]');
validator.check('185.16.22.2').then(result => {
assert(result instanceof spf.SPFResult);
if (result.result !== spf.Pass || result.result !== spf.Neutral) {
console.error(result.message);
}
