A robust email address syntax and deliverability validation library
for Python by Joshua Tauberer.

This library validates that a string is of the form name@example.com.
This is the sort of validation you would want for an email-based login
form on a website.

Key features:

* Checks that an email address has the correct syntax --- good for
 login forms or other uses related to identifying users.

* Gives friendly error messages when validation fails (appropriate
 to show to end users).

* (optionally) Checks deliverability: Does the domain name resolve?
 And you can override the default DNS resolver.

* Supports internationalized domain names and (optionally)
 internationalized local parts, but blocks unsafe characters.

* Normalizes email addresses (super important for internationalized
 addresses!).

The library is NOT for validation of the To: line in an email message
(e.g. My Name <my@address.com>;), which flanker is more appropriate for.
And this library does NOT permit obsolete forms of email addresses,
so if you need strict validation against the email specs exactly,
use pyIsEmail.
