Flystrike Spam Interrogator   
http://www.flystrike.net

Flystrike Spam Interrogator allows the user to test e-mail messages before fully downloading them from the POP server. A Score based on an Inventory of tests helps the user identify unsolicited messages for remote deletion. Messages containing abusive or illegal content can be relayed to the appropriate authorities with a set of automatically extracted headers. A number of pre-written (English, French, and Spanish) abuse reports are provided to help the user. If desired, each e-mail message can be viewed in original form or as a web document (for HTML). For the latter, pictures and hyperlinks are removed for the protection of the user. The user can trace the origin of messages; and ban them according to both MD5 Signature and URL pointers. The banning of these elements allows Flystrike to perform auto deletion of e-mail messages if required by the user. A log of deleted messages allows the user to discover any false positives. A threat list is available that allows the user to enter e-mails associated with particular worms or incorrigible nuisances; messages from those on the threat list are auto-deleted from the remote server before the conventional interrogation is performed. Once Flystrike is configured, the user can set it to perform automatic interrogation of messages on the remote server.

IMFStats

IMFStats gives you statistics and guidance for your Microsoft Exchange 2003 Server Intelligent Mail Filter (IMF). The IMF is Microsoft's server based anti-spam solution. It scores each message on a 0-9 scale based on how likely it is to be UCE. There are few options you can set, and even less logging information, so it may be difficult to gauge how to configure the gateway. With IMFStats, this process becomes easier. You can see on a simple graph the Spam Confidence Level (SCL) statistics, which will tell you where to set your Gateway Blocking and Junk E-mail folder options. Key Features: Automatically scans Active Directory for all Exchange 2003 servers. If each server is reachable by ping, it is then scanned for unique Intelligent Mail Filter registry entries. Only Exchange servers running the IMF will appear in the list. If your server is not found it may still be manually entered. The chart and graph will show the distribution of email messages. If you have had at least 500 messages go through the gateway since the last reboot, the program will tell you appropriate values to use based on the SCL score.
