Finally got Net::DNS to compile and install on XP with Active Perl 5.8. Yea for me.
So I’m experimenting with DNSBL. Neat feature, seems to be working well. Still figuring out which lists are best (without slowing down mail to a halt).
Still can’t get sa-learn working properly. But that’s for tomorrow.
Less spam getting through. Much more than 95% effective now.
