I filed a Civil Lawsuit against USPS but the US attorneys sent me a letter stated I had no ground and asked the Judge

Suing the federal government under the Federal Tort Claims Act (FTCA) is trickier than suing a private citizen. In general, the FTCA is intended to provide monetary compensation for injury, property loss, or death caused by the negligent or wrongful act or omission of any employee of the Government. If you wish to sue under the FTCA, you must first file a claim with the federal agency responsible for the alleged misconduct. The easiest way to prepare your administrative claim is to use the federal government's standard claim form, known as a Standard Form 95 or SF 95, which has boxes for all the information you will need to provide. You can get a copy of the form from the Department of Justice's website (at www.usdoj.gov, type "standard form 95" into the search box) or request a copy from the federal agency to which you will be submitting your claim. Once your claim is submitted, the federal agency has six months to rule on it. If the federal agency rejects your claim or refuses to pay all the money damages you demanded, you have six months from the date on which the decision is mailed to you to file a lawsuit. Again, file your lawsuit as soon as possible after receiving this decision to avoid any chance of having your lawsuit dismissed as untimely.

Same question, same answer. You have to follow the rules and you didn't. http://www.attorneyqna.com/legal-answers/i-filed-a-complaint-against-usps-personel-but-the--454515.html?ref=result_2_title You don't have time to make sure you pay your bills, and it's apparently everyone's fault but yours, and yet somehow you've got time to burden the courts with your frivolous lawsuit, and THAT's what's so wrong.
