JS is client side.. nothing to do with the server.. post your code

<form name="insert" action="insert.php" method="post">
<table>
<tr><td>First Name:</td><td><input type="text" name="first" /></td></tr>
<tr><td>Midle Name:</td><td><input type="text" name="middle"  /></td></tr>

<script language="javascript">
function CheckEmail() {
email = document.insert.Email.value
AtPos = email.indexOf("@")
StopPos = email.lastIndexOf(".")
Message = ""

if (email == "") {
Message = "Not a valid Email address" + "\n"
}

if (AtPos == -1 || StopPos == -1) {
Message = "Not a valid email address"
}

if (StopPos < AtPos) {
Message = "Not a valid email address"
}

if (StopPos - AtPos == 1) {
Message = "Not a valid email address"
} 
return message
</script>
<tr><td><input type="submit" /></td></tr>

For JS try this..

<script language="javascript">
function CheckEmail() {
email = document.insert.Email.value;
Message = "";

if (!email.match(/^\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b$/i))
{
Message = "Not a valid email address";
}

return message;
</script>
