What examples of incorrectly-formed email addresses is it accepting? I can
think of a number of perfectly valid patterns that one will reject, too.

To be frank, attempting to validate an internet email address (as per RFC
2822) is a fool's errand. You could possibly validate the domain name
part, but the local part can pretty much be anything one likes, anyhow. So
on the LHS of the @ symbol, there's no pattern to validate.

And what about this sort of thing:

looks.ok@NotAValid.domain.foo

Are you going to check that the domain is actually registered and active,
and has an SMTP server receiving email? No, didn't think so. So what's
the point?

I can understand forcing a person to enter SOMETHING as an email address,
and maybe type it in twice so as to minimise the chance of typos, but if
they don't want to give you an email address, they won't.

If you want to force a person to enter a VALID email address, then make
sure part of their registration is done via responding to an email to their
designated address...
