Jquery email validation of email and one specific message - ajax

Question

I have a jquery syntax as below
Email: {
required: true,
email: true,
remote: {
url: "emails.php",
type: "post",
},
which validate a field as below;
<td class="field" style="width: 246px">
<input id="Email" name="Email" type="text" value="<?php echo $email; ?>" style="width: 246px">
</td>
<td class="status"></td>
which displays a success/error message in <td class="status">
It validate the data when a valid email ID is entered.
The ajax callback is a simple true/false data.
What i want is, it should also validate when a specific message "NA" is entered in the field. Is this possible??
Here is the complete javascript;
<script id="demo" type="text/javascript">
$.noConflict();
jQuery(document).ready(function($) {
var validator = $("#signupform").validate({
rules: {
ID: "required",
Name: {
required: true,
minlength: 5,
},
Address: "required",
Dept: "required",
Phone: "required",
College: "required",
LDate: "required",
EDate: "required",
Year: "required",
Privilage: "required",
username: {
required: true,
minlength: 5,
},
Email: {
required: true,
email: true,
remote: {
url: "emails.php",
type: "post",
},
},
LibID: {
required: true,
},
},
messages: {
ID: "Enter ID",
Name: "Enter Name",
Address: "Enter Address",
Phone: "Enter Phone Number",
College: "Specify College",
LDate: "Enter Licenseing Date",
EDate: "Specify License Expiry Date",
Year: "Specify Year",
Dept: "Specify Department",
Privilage: "Specify Privilage",
username: {
required: "Enter a username",
minlength: jQuery.format("Enter at least {0} characters"),
remote: jQuery.format("username not available")
},
Email: {
required: "Enter a valid email address",
minlength: "Enter a valid email address",
remote: jQuery.format("already registered"),
},
LibID: {
required: "Enter a Library ID",
minlength: "Enter a Library ID",
remote: jQuery.format("ID is already in use"),
},
},
errorPlacement: function(error, element) {
error.appendTo( element.parent().next() );
},
success: function(label) {
label.html("OK").addClass("checked");
}
});
$('.username').alphanumeric({nocaps:true}).alphanumeric({ichars:'._'});
});
</script>
Thanks in advance :)

I assume you are using the jquery.validation plugin.
If thats the case you can use depends with email rule:
Email: {
required: true,
email: {
depends: function(element){
return element.value != "NA";
}
},
remote: {
url: "emails.php",
type: "post",
},
}
