Install

npm:

npm install reserved-email-addresses-list email-addresses

yarn:

yarn add reserved-email-addresses-list email-addresses

Usage

The string you are comparing with must be converted to lowercase and trimmed of whitespace. The reason we are converting to lowercase is because the dictionary of words we are comparing with are all lowercase, and in order to compare for strict equality, we must have matching case.

It is also highly recommended that you check for strict equality, and for a list of admin-related usernames, you should check for strict equality, starts with, or ends with comparisons as well.

const reservedEmailAddressesList = require('reserved-email-addresses-list');
const reservedAdminList = require('reserved-email-addresses-list/admin-list.json');
const emailAddresses = require('email-addresses');

const email = '"Admin***!!!"@example.com';
const parsed = emailAddresses.parseOneAddress(email);

if (parsed === null)
  throw new Error('Email was not a valid address');

const str = parsed.local.toLowerCase();

let reservedMatch = reservedEmailAddressesList.find(addr => addr === str);

if (!reservedMatch)
  reservedMatch = reservedAdminList.find(
    addr => addr === str || str.startsWith(addr) || str.endsWith(addr)
  );

if (reservedMatch)
  throw new Error(
    'User must be a domain admin to create an alias with a reserved word (see https://forwardemail.net/reserved-email-addresses).'
  );

List

See index.json for the complete list of all reserved email addresses, and admin-list.json for the list of all reserved admin names.
