==Description==
SME Optimizer is an external service that generally enhances the functionality and efficiency of the e-mail system in 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.

The system will on a daily basis check whether your server (it IP address) is listed in international DNS blacklist. Further more it will on an hourly basis check whether your server for SMTP availability . =====Attachment Filter=====The system will (currently only on SME 9.2) check file attachments hashes up against a DNS based system. This will allow an extra check beyond the build-in ClamAV as this check contains malicious file hashes found by other AV engines. This functionality requires you to register for a free VirusTotal public API and whether configure the system to use it. This means that your system will, in the background, build up the server has databases and all other users will benefit. This is listed currently in DNS BlacklistsBeta, so reach out if you want to participate.
The next planned functionality is:
* Providing additional Clam AV signatures including additional signatures created via interface to VirusTotal* Enhanced attachment filter that does not require admin to generate signatures but just configure extensions
