Re: Effective spam filtering need lots of spam
I have a domain that is over 20 years old
Mine are only about 15 years old.
with plenty of email address published in usenet and on the web and archived mailing lists
Yes, me too.
that is the level I need to process so that my spam level is less than 1%.
Well, I use <1% of the training spam you quote, and my spam level is << 1%, with approximately zero false positives.
I don't understand yuour figures.
 It's silly to quote zero, as a single one ever breaks that promise. But my false positive level is negligible.
