I am of the opinion that regex for email address is a bad idea. The only two things that you need to check an email address are:
Does the address contain an @ symbol?
Is there a dot to the right of the @ symbol?
Then just try to deliver to it, and let the MTA do the rest.
Email addresses can be complicated, and there's plenty of valid addresses that can be excluded by attempts at regex validation.

i said “email” but what i meant was “show me a complicated example”. i don’t disagree with anything you said.
