Return Path hosts a widely used and highly accurate blacklist, which is an official list of email server IP addresses that show activity resembling the activity of spammers. This evaluation is based on the percentage of email messages from a particular IP address that are considered unwanted or "spam" by individual recipients as well as email providers and filters through a variety of actions including, but not limited to, complaints, unusual volume patterns, and emails sent to spam traps and unknown email addresses.
