Since not that long after 9-11 (especially the anthrax scares a few months later), every piece of mail in the U.S. can be tracked back to where it entered the postal system. Just a matter of cameras at the sorting center, needed for the automated character recognition for mail routing anyways, and keeping track of which bin in the back of a mail truck contains items from which box.
In addition to any video surveillance that might be available, since they're not tossing the mail around like a lottery drawing the mail is usually in the order it was dropped into the box which makes it easy to track down folks who mailed items before and after to see if they may have noticed any clues.
The days of anonymously sending a letter by mailing the postmaster in a far away city and enclosing another properly stamped and addressed piece of mail for him to drop into the outgoing mail for you are long over.
