An package to interrogate SMTP servers to see if an email exists

Email Validator
How It Works
In laymen, it connects to the server where the email address exists and tries to ask it if it has a record of it. If so it will return something like this:
Successful
{
email: "[email protected],
mx_priority_1: "gmail-smtp-in.l.google.com",
mx_isValid: true
}
Error
{
email: "[email protected]"
error: <error object>
}Not every server will cooperate but most will. Most notably I've run into issues with redhat.com

Example
const { validate } = require('email-validator')
(async () => {
let isEmailValid = null
try {
// Verbose and timeout defaults; Mot needed to use the method.
isEmailValid = await validate({email: "[email protected]", verbose: true, timeout: 2000})
} catch(e) {
// handle invalid email / error
}
})()
