Message Sniffer For MDaemon

Message Sniffer (SNF) is an intelligent anti-spam scanner that uses advanced pattern recognition and collaborative learning technologies to accurately identify spam, scams, viruses, and other email borne malware at your email server or gateway (before it gets to your inbox).

The MDaemon Plugin in installed via our Windows Installer for our SNFServer and SNFClient spam filter software. SNFServer provides message scanning and collaborative IP reputation services (GBUdb) via the XCI protocol. SNFClient provides a command line interface to SNFServer via the XCI protocol. The SNFClient utility can be used do connect SNFServer to virtually any email server or filtering system that supports external antispam and antivirus tools.

The Message Sniffer software is designed to be installed on an email server or filtering appliance. Message Sniffer is driven by a professionally managed rulebase, available via subscription, that is continuously monitored and updated by intelligent machines and highly trained analysts. This teamwork between synthetic intelligence and extraordinary people reduces your administrative workload to a minimum and allows SNF to respond quickly (within minutes) to new threats while also predicting future hazards so they can be blocked before they arrive.

The Message Sniffer software has two components: SNFServer and SNFClient. SNFServer provides message scanning and collaborative IP reputation services (GBUdb) via the XCI protocol. GBUdb responds quickly to emerging threats and saves system resources by providing IP blocking information and modifying message scan results in real-time. SNFClient provides a command line interface to SNFServer via the XCI protocol. The SNFClient utility can be used to connect SNFServer to virtually any email server or filtering system that supports external antispam and antivirus tools.

SNF accurately captures more than 99% of spam without tuning. We calculate this statistic from real-world data collected by our monitoring system using system telemetry, data from spam-traps, user submissions and a comparative analysis with several dozen high quality spam tests.

In addition, Message Sniffer's highly optimized engine has very modest hardware requirements and typically uses only a small fraction of the resources required by other engines. (SNF typically has less than 10% of the CPU requirement of SpamAssassin when processing the same message stream!)

Message Sniffer is used by ISPs, ASPs, SaaS providers, spam filtering services, antispam appliance vendors, schools, businesses, and consultants worldwide to protect systems from spam, scams, viruses, and other email borne threats.

Get the Windows Installer

Use this guide to assist in a fresh install of the MDaemon Plugin, or an upgrade to V3.0.

  1. Download the SNF_CS_Installer.exe from the Downloads page.
  2. Execute the Installer, and follow the SNF Install Tutorial for the MDaemon Install option.
  3. Either have the Installer restart MDaemon, or restart MDaemon at your convienence.

The Technical Summary lists the files that will be placed in the folder you designate for installation as well as the additional files the Installer will be required to touch. The Installer will restart the MDaemon service if you let it.

This version of the Installer uses Curl as the transport mechanism for the rulebase update feature. If you are updating to v3.0, you should either discontinue your current mechanism, or set the rulebase update feature to off. (We strongly recommend migrating to the Curl platform since it explicitly handles the server-file, local-file time stamp conflict.)

If you are upgrading from an earlier version of Sniffer, the SNF_CS_Installer.exe will duplicate copies of any original files which have the same name as a file in the new version, and store them in a folder called SNFRollback (specifically, the MDaemon Plugins.dat file reference and any original .dll files, etc.). If you need to rollback your upgrade for any reason, you may execute the Installer again, browse to your install location, and select Uninstall. The SNF_CS_Installer will work through the rollback file, remove any files belonging only to the new version and return the original files to their proper locations.
