Converting a small php mail app to a cf mail app, is it possible?

Hello;

I am trying to use a small app I picked up and it uses a php email tag in a java scrip / jquery based email applet for a web site. The php tag sends a callback to the jquery when the message is sent, if it doesn't, the jquery throws an error and tells the user nothing was sent. I know how to use a cfmail tag, but I am looking for help with sending the callback to the jquery.

I'm posting both sets of code, the php code, and then the cf code:

PHP version

<?php

    //declare our assets

    $name = stripcslashes($_POST['name']);

    $emailAddr = stripcslashes($_POST['email']);

    $comment = stripcslashes($_POST['comment']);

    $subject = stripcslashes($_POST['subject']);   

    $contactMessage = "Message: $comment \r \n From: $name \r \n Reply to: $emailAddr";

    //validate the email address on the server side

    if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $emailAddr) ) {

        //if successful lets send the message

        mail('/*RECIPIENT EMAIL ADDRESS*/', $subject, $contactMessage);

        echo('success'); //return success callback

    } else {

        echo('An invalid email address was entered'); //email was not valid

    }

?>

This is the cf version I'm working on:

<cfparam name="FORM.name" default="">

<cfparam name="FORM.emailAddr" default="">

<cfparam name="FORM.comment" default="">

<cfmail to="info@astie.com"

        from="#form.emailAddr#"

        subject="Feedback"

        type="html"

        server="mail.asite.com"

        port="25">

<cfmailparam name="X-Priority" value="1"/>

<font face="Verdana, Arial, Helvetica, sans-serif" color="##000000" size="2">

<b>Feedback Form!!</b><br>

  <br>

  <b>Customer Name:</b> #form.name#<br>

  <b>Customer Email:</b>   #form.emailAddr#<br>

  <br />

    <b>Feedback:</b><br>         

  #form.comment#</font><br>

<br>

</cfmail>

Is this possible? I was thinking a cfif statement.. but am a little unclear how to approach it. I can make the jquery available as well if needed, but If I mirror the code in the phpo it should work without having to mess with the java.
Thanks for any help.
