Let's say an earthlink throwaway account spammer sends mail through
earthlink's mail servers (a common enough occurence) then all you've
really succeeded in doing is annoying your users by refusing mail from the
other few million earthlink users. No matter how short a time before you
clean out the database, it's still going to reject more legitimate mail
that spam.
