I have not actually tried this yet. I don't know WHERE in S0 it goes
either, but I figure it will be obvious after about an hour of
head-scratching.

David can answer more authoritatively, but I believe "PreferredMail" is an
optional service to block mail from a list of spam sites. AOL was recently
challenged in court by a professional spammer on freedom of speech grounds,
and won. The court ruled that spam is not constitutionally protected free
speech - HOORAY!

BTW: My list of spam sites consists of a merger of that list, and a list I
got from Panix. It's quite big - 108 lines. I only recently got my sendmail
properly configured to reject email from all domains in the list, with much
help from a friend. The technique is to put the list in a file
(/etc/spam.domains), then put the following into the S0 ruleset of your
sendmail.cf:

FX/etc/spam.domains
