This is what I use... but I learned by flat out rejecting on them (by upping
the scores for those tests) that some senders indeed have bad times.
An interesting thing we encountered was a sender hitting one of those as well
as the INVALID_DATE header rule. Turns out they were leaving the timezone
off of their mailing list software-generated date header, and while they were
sending with a valid PST timestamp, our servers run in UTC so without knowing
the timezone, figured it was 9 hours off.
