Virbl is a project of which the idea was born during the RIPE-48 meeting. The project gets reports of virusscanning mailservers, and puts the IP-addresses that were reported to send viruses on a blacklist.
After fixing the problem that caused the listing. The IP will automatically be delisted 24 hours after the last virus from that IP was found.
Is the information on our site wrong or incomplete? You don't want us to monitor your blacklist? Or do you operate a similar blacklist? We would like to hear from you!
