I've noticed some trojans with addresses from usps.com <http://usps.com> slip through.

Does anyone blacklist based on SPF?

I took a look at the source for SpamAssassin/Plugin/SPF.pm but it only has evaluation rules for whitelisting:
  $self->register_eval_rule ("check_for_spf_whitelist_from");
  $self->register_eval_rule ("check_for_def_spf_whitelist_from");

Thanks,
Julian

I tried blacklist_from *@usps.com with an whitelist_from. (would even themselves out...) problem is.. if I send to xmail, and xmail fwds (incorrectly), OR, dns doesn't answer in time, you lose email.

best to write a metarule. put your def_ whitelist from (7 points), and set up some metarules.
