Default Validate multiple email addresses

Afternoon

I use the following code to determine 'is this a vlid email address'

email=document.userAdmin.uEmail.value;
var expression=/^([a-zA-Z0-9\-\._]+)@(([a-zA-Z0-9\-_]+\.)+)([a-z]{2,3})$/;
if(!(expression.test(email)) )
   {
      alert("Please enter a valid email addres to proceed");
      document.userAdmin.uEmail.select();
      document.userAdmin.uEmail.focus();
      return (false);
   }

Can anybody assit me writing a function which checks for more than one? These addresses will be entered into a text area seperated by a comer in the following format:

abc@somelocation.com, cde@someOtherPlace.com

In short my code does not allow for the validation of multiple addresses seperated by a commer in the one <input type="text"> tag

For others:

String.prototype.trim=function() { return this.replace(/^ +| +$/,'g') }
email=document.userAdmin.uEmail.value;
var expression=/^([a-zA-Z0-9\-\._]+)@(([a-zA-Z0-9\-_]+\.)+)([a-z]{2,3})$/;
emailArray = email.split(",")
var submitOk = true
for (var i=0, l=emailArray.length; i<l; i++)
   {
      if(submitOk && !(expression.test(emailArray[i].trim())) )
      {
         alert("Please enter a valid email address to proceed");
         document.userAdmin.uEmail.select();
         document.userAdmin.uEmail.focus();
         submitOk = false;
      }
   }
   return(submitOk);
