Back in 2002 I asked if anyone had a solution to block or rate limit outgoing web based spam.
What is web-based spam? Comment spam? Wiki defacements? Or do you want to stop spam sent via web mailers? That's their job. They know more about their customers than you, and quite a few of them use HTTPS anyway.
If Yahoo hasn't got rate limits on their "I've got a new email address" feature, for example, they need to fix it, not you or anybody else.
The big boys know what to do. The smaller ones like walla.co.il, jumpy.it and mail.ru to name just 3 out of about 300 I have seen, do not have all those bells and whistles and therefore, in order to protect an ISPs IP address space from not getting burned by spammers, the ISP has to take proactive measures. -Hank Nussbacher http://www.interall.co.il
