Imaginet uses a bespoke spam filtering system aimed at providing the best possible spam filtering with near-zero false-positives. Techniques used include:
- Advanced bayesian statistics
- URIBLs and RBLs: internal, Invaluement ivmSIP & ivmURI, SORBS, GBUDB, Whitelist ZA
- Virus and spam filtering with ClamAV
- Global and customer-operated address blacklists & whitelists
- Strict enforcement of SPF
Spam-filtered mail is delivered to a Spam Quarantine or, if there is enough of a consensus between the systems we employ, discarded.
