Imaginet uses a bespoke spam filtering system aimed at providing the best possible spam filtering with near-zero false-positives. Techniques used include:

- Fuzzy checksums

- Advanced bayesian statistics

- URIBLs and RBLs: internal, Hostkarma, 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.
