<script>
function countaddresses(obj){
lineas = 0;
var string = obj.value;
var array = string.split('\n');
var regMail = /^([_a-zA-Z0-9-]+)(\.[_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+\.)+([a-zA-Z]{2,3})$/;
for (i = 0; i < array.length; i++) {
if(regMail.test(array[i]) == true) {
lineas++;
}
}
document.getElementById('lemails').innerHTML=lineas;
}
</script>
<textarea name="emails" class="widel" onkeyup="countaddresses(this)"></textarea>
<div id="lemails"></div>

Just a tip: your regex does not work on TLD's larger than three characters (.info, .museum)

Just change var regMail = /^([_a-zA-Z0-9-]+)(\.[_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+\.)+([a-zA-Z]{2,3})$/; to
var regMail = /^([_a-zA-Z0-9-]+)(\.[_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+\.)+([a-zA-Z]{2,7})$/;
