  email: /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
};

export default regexps;

I had a quesation about validating multiple email addresses. I'm no RegEx expert but fiddled with the existing regex and it looks like this works:

((((([^<>()[]\.,;:\s@"]+(.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,})))(\s*[,;]?\s*))*)

For anybody needing this :-) or post a better version :-)
