Normalize emails for uniqueness validation. This will convert the email to lowercase, remove dots (.), and plus signs followed by arbitrary strings (+foobar).

Based on normailize.

npm install --save normalize-email

var normalizeEmail = require('normalize-email')

normalizeEmail('[email protected]')         // => '[email protected]'
normalizeEmail('[email protected]')  // => '[email protected]'
normalizeEmail('[email protected]')    // => '[email protected]'
normalizeEmail('[email protected]')  // => '[email protected]'
normalizeEmail('[email protected]')   // => '[email protected]'

Normalization rules vary by domain. The rules implemented by this package are:

1. "plus" — remove first + mark and anything after it
2. "dot" — remove all . marks
3. "none" — do nothing

Emails are normalized by domain as follows:

1. gmail.com — plus and dot
2. googlemail.com (alias of gmail.com) — plus and dot
3. hotmail.com — plus only
4. live.com — plus and dot
5. outlook.com — plus only
6. all other domains — none
