Which would still not be perfect because "foo@bar", "foo@[123.123.123.123]" and "💩 @[IPv6 :::1]" are all technically valid email addresses.

It looks like the only validation that doesn't block something valid pretty much would start and end at "It has at least one @ symbol, and something on both sides".
