It will reject many valid email addresses.

For better guidance on verifying email address values, see the official
recommendations in RFC 3696 <URL:https://tools.ietf.org/html/rfc3696>.

In short: don't bother validating email addresses, the email system is
best placed to do that. Just try using them and catch the failures when
they happen.
