About the Return Path Reputation Network Blacklist

The Return Path Reputation Network Blacklist is a list of IPs currently seen behaving in ways which represent a high risk to the networks of our data partners.

Examples of risky behavior include sending large amounts of mail that is complained about by end users, sending large volumes of mail to addresses which do not exist, and sending large volumes of mail from IP addresses with no reverse DNS or which appear to be dynamic.

Causes of this behavior can vary widely depending on what type of system you send from but can include security issues such as viruses sending mail out through your network, customers sending spam or other malware through your network, or sending marketing mail which causes abnormally large numbers of consumer complaints.

Removing your IP from the Return Path Reputation Network Blacklist
