With the introduction of Microsoft's Exchange Intelligent Message Filter (IMF) in May 2004, the need for a new kind of anti-spam solution emerged. While Exchange IMF provides server-side message filtering and heuristics-based message analysis, IT administrators demand increased functionality to allow them to better control both their organization's security and user's unique requirements. This increased flexibility provided by Nemx SecurExchange will benefit companies of all sizes, especially those that rely solely on native Exchange protection such as the IMF.
The IMF Extensions are part of Nemx SecurExchange Corporate or Perimeter editions along with other content management components or as a separate IMF only product - Nemx SecurExchange - IMF Edition.
SecurExchange's IMF extensions round out the capabilities of Microsoft's IMF by:
White list inbound email via email address, domain, country domain (ie .Dk or .CH) , or IP address
Allowing any number of thresholds to be defined with different actions for each threshold range.
For instance, a SCL rating of 4-6 can be assigned "Quarantine", while a SCL rating of 7-9 could be assigned "Delete"
Providing additional actions available to a triggered message. Additional actions like "reroute", "move to any sub folder", "copy to user", "send a message", and others may be assigned. Moving a message to any subfolder does not require Outlook 2003.
Allowing different thresholds and corresponding actions amongst different user groups.
For instance in a school environment, the "staff" group may have messages quarantined for a particular SCL range, while the "students" group would have those messages deleted.
Augmenting SCLs for a message using SecurExchange's other components like SURBL, header analysis, content, analysis and many other means. - Corporate or Perimeter Editions only
Automatically or manually allow business partner's messages to bypass Exchange's IMF through SecurExchange's Domain capability, minimizing false positives generated by the IMF
White list messages by subject, body, header, originator, or addressee eliminating IMF false positives. - Corporate or Perimeter Editions only
Create Safe Sender's lists to prevent Exchange's IMF from archiving or deleting messages on the SMTP gateway / front end server that exceed the gateway 's IMF threshold.
Categorizing messages based on the concept(s) found within the message using SecurExchange's Concept Manager component. - Corporate or Perimeter Editions only
Exchange IMF Extensions are at no charge when running Nemx SecurExchange Corporate or Perimeter Editions. The IMF Extensions however may be purchased separately as a complete product - Nemx SecurExchange - IMF.
