• about Mailspike


  • The mailspike services empowers your organization to identify and block known spammers. These services are intended to provide all receivers and reputation providers a baseline of data to help block the senders with the worst reputations. All IP addresses listed on our services are being continually monitored and the lists are updated frequently.




    The mailspike services consist of two complementary data sets:

    1. Reputation Data
    The reputation data is compiled on top of specific characteristics and over-time behavior of IP addresses seen sending direct-to-MX email. The reputation data compiles a score which will dictate the likelihood of an IP address being used to send spam. The computed score is then split into several categories as seen below:

     

    Reputation Data


    2. Zero-Hour Data
    Also known as ZBI, this data set lists IP addresses seen participating in a distributed spam wave. It does not take into consideration over-time IP behavior. Instead, it tries to detect viral behavior shared by one or more clusters of IP addresses.
