Nemx Power Tools for Exchange Server

Nemx SecurExchange

January 2005

Version 5.0.8 is a free upgrade to all customers currently within a Support and Upgrades plan. More information on Version 5.0 can be found at our website.


SecurExchange IMF Edition: * New Product *

SecurExchange IMF is a new low cost plug-in that has been designed to address the short comings of Microsoft’s Intelligent Message Filter (IMF) offering. The IMF albeit good at detecting spam can have a high false positive rate resulting in lost business mail or an excessive amount of time spending in reviewing the archive folder. What is missing is an easy to administer white list and threshold mechanism. Nemx SecurExchange – IMF Edition, provides this ability to white list email addresses or domains and can invoke different actions based on the Spam Confidence Level (SCL) for a message. Nemx SecurExchange adds a few configuration dialogs to extend the IMF and can be “up and running” in minutes safeguarding your important business mail. Nemx SecurExchange – IMF is priced at $249 US per Exchange Server.

SecurExchange – IMF improves Exchange's Intelligent Message Filter (IMF) usability by:

• adding the ability to control thresholds and actions on a group by group basis, allowing your organization greater control in dealing with lost mail destined for sensitive users

• bypassing IMF processing by addressee, domain, or “self-sensing” white listing ensuring true business partner’s emails are delivered

• offloads administrators “un-archiving” tasks to users by moving messages to different spam folders or deleting the message based on the SCL value and recipient.

Nemx Power Tools awarded Editor’s Choice by Windows IT Pro magazine:

We would like to thank all the customers that have provided great ideas and suggestions for Nemx Power Tools over the years. It is these comments, both good and bad, that have made Nemx Power Tools a leading Secure Email Content Management solution as evidenced by a recent Editor’s Choice award by Windows IT Pro magazine. Windows IT Pro awarded this honor to Nemx Power Tools based on some of the following factors: “offers a broad range of filter technologies”, “has powerful options that let you customize the product according to your business needs”, and “makes it easy to configure these options”.


Nemx Power Tools – Advanced Edition:

A new version of the Advanced Edition of Nemx Power Tools has been posted on our web site. This new version improves upon the memory and performance aspects of the product and provides up to 3 times faster throughput for the scanning of internal email in both real time and background “after the fact” scanning modes.

With a majority of business communications now done via email, an effective internal policy management should be in place to prevent confidential or proprietary information from getting outside or even inside to the wrong employees and to provide an email environment for staff or students that is free from sexual, racial or other types of harassment. The Advanced Edition of Nemx Power Tools provides the necessary tools to fully provide a Secure Content environment for your Exchange Server and to remove these possible threats to you organization or institution before they occur. Ignoring these threats can open your business and your messaging system to a number of potentially damaging and expensive consequences, including significantly lower morale and productivity, and open your company or educational institution up to the threat of litigation.


Status Log - Aging:

Nemx Power Tools and Nemx SecurExchange maintain a log of status events, including messages which have been triggered by a Spam, Content, or Concept rule, along with the particulars of that message. This status log is called NMXXSP.log and is found in the main Nemx directory. Over time this file can grow quite large and breaking it apart can be quite tedious. With the current build of Nemx Power Tool and Nemx SecurExchange, the NMXXSP.log file is “aged” each night at 12 midnight. Old log files can then be deleted or archived, saving disk space and decreasing the overall review time.

Quarantine Cleanup:

In Exchange 2003, and 2000, messages quarantined by Nemx Power Tools are kept in the Quarantine sub-directory of the main Nemx directory. When a message is Released or Deleted through the Outlook plug-in or via the Release form, the corresponding message in the Quarantine directory is deleted. However, if the quarantine release notification message is ignored, then the corresponding message in the Quarantine directory will not be deleted. Over time, the contents of this directory will increase. The ability to “age” this directory is now part of the latest build of Nemx Power Tools or SecurExchange. The default “keep” period is 60 days, however this period may be modified through the registry.
