Microsoft Working On Greylisting Anti-Spam Solution

from the one-way-to-do-things dept

While others are saying that the only way to stop spam is to make people pay for email, others are coming up with slightly more creative solutions. Realizing that having people actually pay money to send emails brings up a lot of other problems, it appears that Microsoft is picking up on the idea of greylisting by creating their own style of spam delay technology called "Penny Black". The idea is that if you're sending email from an unrecognized location, the server will slow your machine down temporarily, making it much more expensive for the spammer - who needs to get more machines and more bandwidth to keep sending out the same number of emails. Of course, these days, with spammers hijacking others' machines, they might not care so much.
