It'll take some CPU process from your system to compares w/the list,
there's no agreement or such. Since this afternoon, my mail log logged
23442 spams denied from njabl, 6893 spams denied from spamcop, 6084 spams
denied from osirusoft. DNSBL might not be 100% perfect, but close enough.
Very much worth the effort to put in a few lines in your sendmail.cf.
