Как написать регулярное выражение для электронной почты, которое найдет начало и с пробелом, нет ли какого-либо электронного письма?

var stringThing = '[email protected] everyone, I stuck with a problem. I'm trying to find the emails from the [email protected] string. I need a regexp which will find the email in starting and in middle with space. like it should detect the [email protected] and <space>[email protected]. here in middle of the string the email should start with space. I'm trying with below regexp it is shibbydibby.net not working. ';

var emails = extractEmailsFromString(stringThing)
console.log(emails);

function extractEmailsFromString(str){
    return str.match(/(([^<>()\[\]\\.,;:\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,}))/g);
}
