Validates email addresses according to RFC 5322 rules. Note: a valid email might not exist. This code just checks if the address adheres to the official guidelines, but doesn't connect to any mail server.
Can be used as a script (python email_validator.py) or imported into other projects by using the validate_email() function.
Requires Python 3.4+ and no extra modules (just 're').
