Buyer provided wrong address. How to handle reshipping of item?

[tjrsales-100]

I'm dealing with a zero feedback buyer who provided an invalid address in the ebay system.  It was a buy it now purchase, substantial value ($275).   He didn't pay until after I filed a case, and waited until the last day before the case closed.  Item was shipped to the address shown on ebay/paypal.  Tracking shows the item is on its way back to sender because of invalid address.   The buyer wants me to reship.   Is there a current procedure for handling such situations?   I sent him a message explaining he would need to fix his address and pay for reshipping.  No response.  I don't have much confidence in this buyer and don't want to reship without seller protection.
