DSPAM is a scalable and open-source content-based spam filter designed for multi-user enterprise systems. On a properly configured system, many users experience results between 99.5% - 99.95%, or one error for every 200 to 2000 messages. DSPAM supports many different MTAs and can also be deployed as a stand-alone SMTP appliance. For developers, the DSPAM core engine (libdspam) can be easily incorporated directly into applications for drop-in filtering (GPL applies; commercial licenses are also available).

The basic role of DontReg.com is to help decrease the number of spam mails in your mailbox by enabling the use of a temporary email address, and by offering a public editable database, which contains login information to sites which force users to register.
