I've been cutting out my name/address and printing "REFUSED RETURN TO SENDER" in blue marker, and putting it in the post office mail box. I've wondered whether they would track me, although seems like we can refuse delivery, no?

Maybe they'll be recycled into something useful like toilet paper.

They get the names/addresses from the public information voter registrations, so the nonspecific "or resident" wouldn't be applicable.

and it included "or resident" on the label. The mailman told that because of that, it wasn't improperly delivered, and therefore could not be returned to sender. I guess it's a way to avoid having bulk junk mail sent back.

It seems to me that if the mail doesn't include that, and it's not to your name, you should be able to send it back. But honestly, I am not sure what the specific USPS rules and policies are.

which would not be to random people.

If I may respond, unless a change of address is entered, the mail with the known names of the addressee’s will still be delivered.

Honestly, just because you say they don’t live there doesn’t mean it’s a fact. That’s where the Change of Address makes it a fact.

Not trying to be rude to you. You’re just handling it wrong and you’re making yourself mad.

I KNOW the law...It's just annoying and I needed to vent. But yeah...wish I could make a change of address FOR her. She's in a shelter/transitional living down in Placerville somewhere. Got a restraining Order and she even has an ankle bracelet to keep her from coming here... she tried to literally kill me in October.

I just can't wait till the trial is over and I can then forward all her mail to the JAIL!

Try collecting all of her mail that gets delivered. Put it all in a box and give it to the judge on the day you testify. If there's a restraining order, tell them that you feel you're being harassed.

Alternatively, just throw it away or shred it. No evidence.

Then at least the senders might realize they're wasting their postage sending it to your address, and either look for her elsewhere or give up.
