a while back...I have never had any desire to study it. :-)

I can't remember the story above overnight mail. I know they have the legal monopoly on mail. FedEx got (actually gets) around it by only delivering to addresses (not PO Boxes). Also, there is some legal justification on certain things (things have to be postmarked by a certain date (cough absentee ballots cough)) and FedEx's airbills do not meet the legal definition.

But I can easily believe your story (but no, I'm not looking it up either)
