It is hard to tell unless you give more details, so I am guessing "Return Receipt". = it can either mean that you have been given/sent a receipt for something you bought OR you should return the receipt if you were not happy with the quality of the goods. Your document:was received by: = that whatever document you sent to a company has received it and it should have the name of that person. OR if you have to return the receipt, send it to the person whose name appears next to the words"Your document was received by"
