Indeed. Just blackhole any and everything that replies with an AntiSpam UOL
message, and make sure all your ML manager drop subscribers that cause such
a bounce. That's what most Brazilians do (we have to deal with it quite
often, it is one of the top-three ISPs in the country). That !@$@#$
challenge-response is optional, not every UOL address has it enabled, thus
we can't justify blackholing UOL itself.
