Tens of thousands of pieces of mail were delayed in getting to Mainers in more than a dozen towns Monday amid a policy shift within the U.S. Postal Service. The Portland Press Herald reports that as much as 80,400 letters and other pieces of mail were left behind at the Postal Service’s Scarborough distribution center on Monday because a new policy prohibits any late trips. A union president told the Portland newspaper that the mail was already sorted and just needed to be loaded onto trucks.
