False positive for .email() validation with sub-domain present?

[JK-WP]

I've come across what I believe to be some false positives with the string .email() validation, where it doesn't appear to like subdomains. Here is a simple repro:

import { z } from 'zod';

const data = [
  '[email protected]',
  '[email protected]',
  '[email protected]',
  '[email protected]',
];

for (const email of data) {
  console.log(z.string().email().safeParse(email));
}

which produces:

{ success: true, data: '[email protected]' }
{ success: false, error: [Getter] }
{ success: true, data: '[email protected]' }
{ success: false, error: [Getter] }

This is flagging up validation errors in my project for real email addresses resembling the 4th entry in the above repro.
I can see from the code that this behavior is driven by a rather formidable looking regexp; please could you clarify - is a validation failure on an address such as [email protected] intentional? Thanks!

Nope, not intentional. Thanks for reporting. It's hard to find a regex that pleases everyone, but this is a pretty glaring flaw.

Here's another valid example I noticed today, that can be common in the US.
[email protected]

Is anyone else working on this, if not I'd be happy to pick it up!
