The expiration date on mail is WRONG.
If mail expires on a date, then it must be available THROUGH the end of business on that date. Mail expiring on the 9th means it is available still because it has not expired, because it *IS* the 9th.. Expired on the 9th, when it is STILL the 9th is not possible since it is STILL the 9th. Please fix the expiration date, or fix the expired date.
