Impressionwise Email Verification and Spam Trap Removal

Threat Intelligence Center


Blacklist Profiles\Composite Blocking List (CBL)

The CBL takes its source data from very large mail server (SMTP) installations. Some of these are pure spamtrap servers, and some are not. In other words, the CBL only lists IPs that have attempted email connections to one of our servers in such a way as to indicate that the sending IP is infected with a spam-sending virus or worm, acting as a open proxy for the sending of spam, OR, IPs primarily used in the operation of botnets. The CBL does not list based upon the volume of email from a given IP address.
