✔ Flow Control: Blocks spam recd within short period contains diff sender domains but identical
body.
✔ Fingerprint: If at least one MD5 hash is contained in the spam database then email is blocked.

✔ Dynamic Host Reputation Works locally, determines a reputation for each IP emails are sent from.
✔ ZLA Spam URL:In first 5 URLs, If at least one is categorized as "Spam URL" then email is blocked.
✔ ZLA Spam Flow:It blocks spams that are received within a short period of time.
✔ ZLA NDR This method is based on phrases which are typical for NDRs.
✔ ZLA Spam Bayes is a "classical" Bayesian Classifier based upon shingles instead of words.
