Returns true if email is an autoreply according to the email headers.
Please open an issue if an email isn't properly detected as autoreply :)
npm install --save is-autoreplyHeaders can be String, Buffer or Object (key/value). In case of String or Buffer, the headers are automatically parsed.
const isAutoreply = require('is-autoreply');
const emailHeaders = { 'X-Auto-Response-Suppress': 'OOF' };
if (isAutoreply(emailHeaders)) {
console.log('The email is an autoreply');
}
