Expired records from the SpamAssassin cache

No - this a a newish feature where MS keeps its own cache of recent spam
hashes. Its a lot quicker to look in this system than replay the entire
message through SA. If it finds a hit it gets marked as spam, if not it
proceeds to run SA. MS keeps this info for about 1 hour (varies) and the
expires you are seeing are 'old' records being deleted from MS cache.

Given most people get more spam than ham now-adays this technique can
dramtically increase speed of processing (anywhere up to 10x).
