Your mission

Score a message date against the year the server is actually running in.

today's brief

January 1, 2010. SpamAssassin wakes up and starts scoring mail from the future. A rule written years earlier matched any Date header in 20[1-9][0-9] and added 3.2 points for it, which was fine right up until the calendar caught up with the pattern. Legitimate mail dropped into spam folders worldwide that morning while admins hunted for the rule. The year had been baked in. Take it out.
