I'm doing the following:

```
email = 'bob@luv.southwest.com'

domain_rules = [/craigslist.org/, /evite.com/, /ziprealty.com/, /alleyinsider.com/, /fedexkinkos.com/, /luv.southwest.com/, /fastsigns.com/, /experts-exchange.com/, /feedburner.com/]

user, domain = email.split('@')

domain_rules.each { |rule| return true if !domain.match(rule).nil? }

```

Problem is this is case sensitive. Is there a way to make this all case insensative, without having to add /i to the end of every single rule?
