- Keyword scanning of emails:
Our scanning methods include a scoring system such that emails are scored based on a number of criteria. If the score is above a threshold, then that email is flagged as spam. The SpamZone team constantly monitor & update these keywords based on current activity so there is virtually no lost messages.
- Checksum technology:
SpamZone monitors email traffic through the Internet and uses checksum technology to keep track of the number of times a particular message has appeared on the Internet. If a message has appeared over a certain number of times, it is categorized as known spam. Checksums of known spam messages are utilized by SpamZone to block spam messages.

Several algorithms are utilized to verify the authenticity of a message. Some of these are simple checks to verify that the “from address” is authentic. Some are more complex relating to SMTP protocol.
