From DM News: "E-mail marketers may soon yearn for the days when Mail Abuse Prevention System LLC was their
biggest pain in the neck, according to sources from the anti-spam camp.
In the wake of the recent settlement between Experian eMarketing and MAPS, some Internet
service providers have begun subscribing to other so-called block lists, or lists of suspected
spammers that ISPs use to filter unwanted e-mail. And these other lists' maintainers are not nearly
as friendly as the folks at MAPS, sources say."
