Sender Policy Framework (SPF) added to Email Defense

Saturday, June 25th, 2005

Email Defense has been updated with several significant enhancements. These include an improved user interface and full support for Mozilla FireFox. Additionally, this new release includes the following significant addition:

Sender Policy Framework (SPF):

  • We are adding a Sender Policy Framework classifier to the Spam detection system to help identify and block fraudulent “spoofing” emails —  those sent by Spammers using forged “From” addresses.
  • For each inbound message, the SPF classifier will look up the sending domain’s Domain Naming System (DNS) record and its list of authorized IP addresses (if such are specified). Messages that carry an IP address not found on the authorized list will be given a higher ‘spam-likelihood’ score.
  • By determining whether or not the relationship between the DNS record and the IP address is legitimate, Email Defense can more accurately filter out fraudulent spoofed emails. As a result, this reduces risk for end-users who might be duped by the email into divulging confidential personal information.
  • LuxSci supports the addition of entries to your DNS records which will support SPF — to help make it harder for Spammers to forge email from your domain. If you would like us to add an SPF record to your DNS entries or if you would like help in determining what SPF records to add yourself, contact our support team.

New “Bounce” Email Filter Action

Saturday, May 28th, 2005

 LuxSci’s custom email filtering tool now supports a “bounce” action. Using this new action, users can make custom filters that bounce selected email messages back to the sender with a “User unknown” error. Other actions already supported by this tool allow you to forward messages, save messages to a selected folder, delete messages, add custom headers, and more.
