SNF MDaemon Plugin

This product is for use on Win* systems using Alt-N's MDaemon version 8 and above. The plugin provides message scanning features that allow for rejection based on IP during the SMTP session and otherwise add headers to messages that are later interpreted by MDaemon's built-in SA implementation or by your content filters.

You can download this package from our Products page.

This distribution includes:

• snfmdplugin.dll - SNF Plugin for MDaemon. (SNF Engine & XCI Server)
• SNFClient.exe - Compiled for windows systems. (SNF Client Application)
• snf2check.exe - Compiled for windows systems. (SNF Rulebase Authenticator)
• getRulebase.cmd - Rulebase update script. Wget and gzip utilities included for convenience.

snfmdplugin.dll provides a high performance, multi-threaded implementation of the SNFMulti anti-spam engine designed to work directly with MDaemon. This implementation includes two scanning functions: The first allows MDaemon to discard messages during the SMTP process based on IP reputation information from GBUdb. The second performs a content scan on the message aided by GBUdb data and injects headers that are later interpreted by MDaemon's built-in SpamAssassin implementation. The plugin also includes a TCP (locahlost) server that accepts XCI requests from local applications or the SNFClient command line utility.

SNFClient.exe provides a command line interface to SNFServer.exe by translating command line scan requests to XCI requests and interpreting the result. SNF scan result codes can be retrieved as the %errorlevel% in scripts or directly by the calling program. Declude, eWall, and mxGuard are examples of message filtering systems that typically call SNFClient.exe to scan messages.

snf2check.exe is a command line utility that tests SNF rulebase files for authenticity and integrity.

getRulebase.cmd provides a rulebase update mechanism using the open source utilities wget (for retreiving the rulebase) and gzip (for decompressing the rulebase file). The script is designed for use with SNF's update-script feature to provide up-to-the-minute filtering rules automatically.
