I got switched to USPS production Account still problems

Question

Last night I mailed USPS customer care executive and they had switched my account to production server in USPS.I got mail from them in which I got this message

Dear USPS Customer,

Thank you for contacting us.  Congratulations on completing your testing using the U.S.
Postal Services Internet Shipping Application Program Interfaces (APIs). 
Your profile has been updated to allow you access to the Production Server. 
1. The Production Server URL is: http://production.shippingapis.com. For APIs calling the secure server, the URL is https://secure.shippingapis.com. 
2. There is a line of code that refers to "shippingapitest.dll".  You'll need to remove the word "test".

In the test server code I was using

$usps->setServer("http://testing.shippingapis.com/ShippingAPITest.dll");

Now I tried using this code today

$usps->setServer("http://production.shippingapis.com");

even I tried this code to get responce

$usps->setServer("http://production.shippingapis.com/ShippingAPI.dll");

Please any one used USPS in past help me.

Here is the link which helped me to test USPS in Test serverlink text

Thanks in Advance
