Reputation Collection

Roaring Penguin Software Inc. has built a system to collect IP reputation information about SMTP clients. We invite interested parties to join in creating a standard protocol for reporting and collecting this information.

We have an Internet draft available in HTML and plain text format that describes our protocol.

Working Perl client code may be downloaded from this site (here's a direct link to the tarball.)
