The company has to review any newly installed module? Sensible. But what about your code, doesn't that have to be reviewed? What if you just make Email::Valid part of your application? Or just copy and paste the relevant code? How long did your company take to review perl itself?

Anyway, your regex is just too trivial to take serious. It would fail on every email address I create for registrating at a website. Rejecting email addresses that don't start with a \w character is as useful as rejecting street names that don't start with a vowel. You're rejecting perfectly valid email addresses, and on the other hand, you are accepting anything that starts with a \w character, and contains a @ and a dot. Which would mean you'd accept the text of this posting as a valid address, yet reject "this is valid"@example.com.
