Postal Locations

I've lived in my house for almost 2 years. What can I do to stop getting mail from the 5 different previous people who lived here? I've sent it back to sender as "does not live here" I've left notes for mail person that I only want my mail with my last name. My name is on mailbox. I'm about ready to save it all up in a trash bag until they cant carry it. I've left up to 20 -30 pieces of mail that's not mine attached to mailbox. Am I going to have to start throwing it away? Please help me get my mail only!!! So frustrating!!

I sell things on EBay and I chose to use USPS in order to support them. I packed several different things in used priority envelopes that I had turned inside out so you couldn't see "Priority Mail." The next day I found my packages on my porch with a letter attached saying I could not use these envelopes even if they were turned inside out. The word not was all in caps. I found this to be extremely rude. I also find it to be a sad thing that the USPS or at least this particular location does not support reusing products to help our environment. I guess I should have chosen UPS where I used to work.
