Is it possible to add a check for a trailing character with a isEmail rule?

Hello,

Basic isEmail rule works as follows:

function(value){
	return (/\\S+@[^@\\s]+\\.[^@\\s]+$/).test((value || "").toString());
}

You can add your own custom rule to check any required criteria:

webix.rules.customRule = function(value, valuesObj, inputName){
     // a rule function gets ui.form as `this` in scope
}
