Nope. Brightmail uses live geeks 24/7 who look at digested mail from
spamtraps and manually update filters. It's incredibly labor intensive.
The closest automated thing is the MAPS RSS which lists open relays
that send spam. Many spam traps (including mine) autoforward stuff
for testing and listing. To prevent spoofing, people who the manager
knows get passwords to put in the submissions that let them bypass his
manual scrutiny.
It works pretty well, blocks a lot of spam for me.
