Message Sniffer For Communigate Pro

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).

SNF4CGP is an antispam & antimalware plugin for CommuniGate Pro Mail Servers. The (CGPSNF) "helper" not only produces X-headers that can be used with CommuniGate filter rules like most CommuniGate plugins, it also provides additional actions that can be configured per SNF result code to improve system performance and support more sophisticated message processing schemes.

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.

SNF4CGP (CGPSNF) does everything a typical CommuniGate filter plugin does and a bit more.

In addition to providing X- headers that can be used with filter rules, CGPSNF can also be configured to take any of these actions (configurable by result code, of course):

Configurable Actions
Allow This is the typical CommuniGate plugin response. CGPSNF will provide X- headers as configured in snf_engine.xml. The X- headers can be used to trigger CGP message processing rules.
Bypass This action bypasses SNF4CGP -- the message has been scanned and logged, but CGP is not provided with headers and no additional action is taken.
Delete This action tells CGP to discard the message.
Hold This action takes the message as it was provided by CGP, injects the SNF headers, and then puts that message in a folder of your choice for later processing. CGP is told to discard the message. This is a great hook to use if you are a service provider and you want to build sophisticated quarantine and/or policy review processes.
Reject This action tells CGP to reject the message with the provided reason.

CGPSNF can also be configured to add it's log entries to the CGP log for easy review -- even if the log is not stored as a file by SNF. To turn off log file generation while allowing SNF4CGP to provide log entries to the CommuniGate log use mode='api'. This works for both XML or Classic log entries.

Also -- just like SNFServer, the XCI interface is provided so you can use SNFClient for GBUdb manipulation or "out of band" message scanning.

The full SNFServer engine is in place whenever the CGPSNF plugin is active.

As always - there is no need to restart SNF after making changes to the configuration -- so you can change these options on the fly as needed.

Get SNF4CGP

Message Sniffer plugin for CommuniGate Pro Mail Servers.
Each distribution contains CGP plugin installation Documentation.

SNF4CGP integrates with CommuniGate as a standard addon and fully implements the CommuniGate plugin specification. In addition, SNF4CGP has been designed to provide as much flexibility as possible based on our work with other customers who use CommuniGate in their online filtering services or in their corporate networks. As such, the SNF4CGP plugin is not only a great filtering option for CommuniGate but it also provides a solid base for highly customized filtering solutions.

Note that in addition to the binary distributions usually found for CommuniGate plugins, we also provide a source code distribution that can be used to compile CGPSNF for platforms where we do not provide binary distributions. Use the GNU g++ compiler or MinGW (that's what we do).
