That's an urban legend. There's no way to prove that you didn't mail yourself an empty envelope and insert it later.
That's not entirely true. If the envelope bore a stamp from when you mailed it and you testified about how you created it and mailed it and received it, it probably would be admissible evidence of your creation. The other party would then have the burden of proving, probably through the testimony of a forensic expert, that your evidence was doctored. But if it wasn't, they probably wouldn't be able to prove it. It's not a substitute for registration, but it is a form of evidence.
