SME Optimizer is an external service that generally enhances the functionality of the SME Server. The first functionality is a SME dedicated DNS Blacklist which is partially based on the user contributions. With SME Optimizer you provide data about your spam rejects and in return you get access to a large DNS blacklist. This blacklist is both providing IP as well as URI based lists and comes as a configuration option to SpamAssassin.
The DNS Blacklist has as of today (October 2016) around 1.4 mio. Spam, Malware and Ransomware IP addresses as well as around 350.000 URIs. These will be provided as part of the DNS Blacklist.
