If you want to implement a similar effect to the new yahoo and
aol DMARC policy by SpamAssassin, use rules similar to the
default rules in 60_adsp_override_dkim.cf:
adsp_override yahoo.com custom_med
adsp_override yahoo.com.ar custom_med
adsp_override yahoo.com.au custom_med
adsp_override yahoo.com.br custom_med
adsp_override yahoo.com.cn custom_med
adsp_override yahoo.com.hk custom_med

Indeed. This is precisely the reason it is useful to *override*
by a local rule whatever some domain publishes or not publishes.
