Answer 1

The newest release of angularJs (1.5.7) includes some email address validation improvements.

You can check the commit here.

Line 28 corresponds to the committed regex:

var EMAIL_REGEXP = /^(?=.{1,254}$)(?=.{1,64}@)[-!#$%&'*+\/0-9=?A-Z^_`a-z{|}~]+(\.[-!#$%&'*+\/0-9=?A-Z^_`a-z{|}~]+)*@[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?(\.[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?)*$/;

Below the directive's code you have the tests to validate the regex. It does check for white spaces.
