In depth: CIMGate™ - Spam Filtering Service
No Spam! No Lost Messages!


CIMGate™ works using a few different components:

  • CIMGate™ - First Layer (The gateway)
    • CIMGate™ Immediate Trust DNSRBL is checked.
    • If IP is not in the DSNRBL, SPASA is involved
      • Scoring System
        • Trusted DNSRBL's
        • Other DNSRBL's
        • Statistical Probability
          • Previous spam database compares messages
          • Spam database comparator starts
    • If IP is in Immediate Trust DNSRBL, message is blocked and message characteristics are stored in signature databases.
    • If IP is not in Immediate Trust DNSRBL, the SPASA system begins. If SPASA determines it to be spam, it will add signatures to the databases and if the score is high enough, and certain criteria is met it will be added to the Immediate Trust DNSRBL.
    • If IP is not in Immediate Trust DNSRBL and SPASA determines message to be legitimate, it is forward on to the mail server for delivery.

This system is quite complex and involved but the above flow chart should help explain how it operates. CIMGate™ is entirely self-sustaining and self-updating with little to no human or user input.
