title: How to configure a magento 1.7.2 multistore with PayPal multi accounts ?
body: <p>I have a magento 1.7.2 running in multistore mode, how can I set a paypal IPN for each site? (The two sites use different paypal account.) 
  Looks like I can set the paypal IPN only on the default configuration. 
  Any tips? 
  thanks</p>
