Resolve the domain of a syntactically valid email address to see if there is even a chance of deliverability. Also checks against a large list of disposable email and other junk/unwated address domains and rejects those. It also checks the email address against the (updated) zod reasonable email regex and filters out unreasonable email addresses.
npm install resolve-email
import { resolveEmail } from 'resolve-email'
// Validate the email address before passing it in here:
const results = await resolveEmail('[email protected]')
console.log(results)
// results.emailResolves true/false
// results.mxRecords [array of mx records and priorities]
// results.error any errors that may have occurred.This module was adapted from nodemailer/nodemailer-direct-transport
The disposable email domain list is generated from the following data sources:
- https://github.com/romainsimon/emailvalid
- https://github.com/disposable-email-domains/disposable-email-domains
