  // Can also be called with these default options
  await validate({
    email: '[email protected]',
    sender: '[email protected]',
    validateRegex: true,
    validateMx: true,
    validateTypo: true,
    validateDisposable: true,
    validateSMTP: true,
  })
}

If you want to validate domains with TLDs that are not supported by default, you can use additionalTopLevelDomains option:

await validate({
  email: '[email protected]',
  sender: '[email protected]',
  validateRegex: true,
  validateMx: true,
  validateTypo: true,
  validateDisposable: true,
  validateSMTP: true,
  additionalTopLevelDomains: [ 'ir' ]
})

For a list of TLDs that are supported by default you can see here.

Default options can be found here
