MAPS is the reverse of SPAM. It stands for Mail Abuse Prevention System. It has 5 lists :
- RBL
- DUL (Dialup Users List), contains IP of SOHO and home users
- RSS (Relay Spam Stopper), hijacked mail servers
- OPS (Open Proxy Servers), naively open mail servers
- NML (Non-Confirming Mailing Lists), marketers who use opt-out lists
The history of MAPS is the history of DNSBL itself. It is a pioneer in the antispam field.
