E-mail reputation firm Habeas, Mountain View, CA, said today it is tracking the reputations of millions of IP addresses, not just those of its certified e-mail senders.
It is launching SenderIndex, an e-mail reputation database of more than 60 million IP addresses and domains, segmented into three categories: Habeas SafeList, Habeas AcceptList and Habeas BlockList.
While it has always tracked IP addresses that pass its certified e-mail accreditation program on its Habeas SafeList, Habeas now tracks addresses that also do not pass its certification tests.
“This is a comprehensive reputation database, which has information about positive and negative reputation,” said Des Cahill, CEO, Habeas. “ISPS receive millions of e-mails from IP addresses, every day they are trying to figure out which ones are legitimate and which ones are not.”
The new Habeas AcceptList represents IP addresses that have passed all of Habeas’s Reputation Engine tests and are determined not to be bad senders, such as spammers or phishers. But, these IP addresses have not passed the Habeas Certify e-mail accreditation program.
The Habeas BlockList includes IP addresses that fail the bulk of Habeas’s reputation tests and appear to be spammers or phishers.
