Invaluement

Overview

Invaluement collectively operates three blocklists: InvaluementURI, InvaluementSIP and InvaluementSIP/24. Their list services are packaged into spam filter and protection products.

How it works

Invaluement has the following criteria for adding domains or IP addresses to their lists:

• InvaluementURI lists domains and IP addresses found within links in the body of spam emails.
• InvaluementSIP lists IP addresses which send a high percentage of spam
• InvaluementSIP/24 blocks larger IP ranges where patterns of spam-sending have been detected through the InvaluementURI and InvaluementSIP lists.

Remediation

Listings last until Invaluement is satisfied that the offending sender has taken the appropriate steps to mitigate the problem. This blocklist does support a manual request to remove or delist your IP Address from their database.
