      My opinion is you're fighting a losing battle trying to reject
      spam using header_checks. Rather use RBLs, RHSRBLs, and some
      common rules to prevent bots. How far you go with these
      depends on your tolerance for false positives, but you should
      be able to get most stuff without constantly updating rules.

      Check recent archives for discussions of rbls and rhsbls to use.

      You can add greylisting and SpamAssassin to catch the rest.
