Answer 1

Read Stop Validating Email Addresses With Complicated Regular Expressions.

As it says, this email :

"Look at all these spaces!"@example.com

is perfectly valid.

Conclusion :

1. Don't use a complex regex to validate email. /@/ is fine to check most user errors
2. Validate by sending an email and waiting for answer

Seriously, any attempt at solving the problem with a complex regex is doomed and usually keeps being worse with fixes
