The output looks like this:
AVG (TOTSCORE/COUNT) -- EMAIL|ip=IPBASE
0.0 (0.0/7) -- email@example.com|ip=208.192 21.8 (43.7/2) -- firstname.lastname@example.org|ip=200.106
AVG is the average score;
TOTSCORE is the total score of all mails seen
COUNT is the number of messages seen from that sender;
IPBASE is the AWL base IP address.
AWL base IP address is a way to identify the sender's IP address they frequently send from, in an approximate way, but remaining hard for spammers to spoof. The algorithm is as follows:
- take the last Received header that contains a public IP address -- namely one which is not in private, unrouted IP space.
- chop off the last two octets, assuming that the user may be in an ISP's dynamic address pool.
