One useful factor of ham is that it's not time-sensitive; a mail that

mail archives, or submissions of relatively old mail, if necessary.

This may be a false assumption.  A spamvertised or spam sending
domain from 2003 could have expired and been re-registered by
a different organization.  Same for ham.  Both ham and spam
should have expiration times.  1 year would probably be good,
since spamvertised domains probably don't get renewed.

yep, I was talking with a SURBLer about this last week I think.  we
should probably add meta conditions ot the URIBL ruleset to ensure
they don't fire at all on old messages.

This is a patch to the Reuse plugin I'd like to see, if someone has any ideas please speak up.
