Domain black-lists aren't particularly useful, because domains are cheap
enough to register that spammers could send one load of spam from a given

or they have some pretense of legitimacy, then a blacklist could have some
effect.
Blacklists can be updated during a spam run, which makes them
somewhat useful. Also, the domain-based blacklists can be mined to
discover registrants (or registrars) who are associated with spam.
I thought the point was that white lists would become meaningful because
people couldn't ride on someone else's good reputation, as they can now, and
service providers could be held accountable for bad users sending mail
within their domain.
LMAP isn't a whitelist. It's a publication of consent information.
