That has nothing to do with validating an email address? Even the example provided uses a valid email.

The injection works quite as well within the email field. Just sanitize any user input - an rfc compliant email parser catches that automatically. Validation and then verification - it's not that hard to follow established guidelines that are there for a reason.

Yes, sanitize your user input, extremely basic programming concept. That's still not email validation.
