I've noticed some trojans with addresses from usps.com

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.
