Annual Subscription Model
SecurityGateway for Email Servers is now licensed on an annual subscription model and includes technical support that is valid for 1 year (12 months) from the purchase date.


Outbreak Protection and CYREN AntiVirus Now Included
The ProtectionPlus add-on is no longer needed to add an additional layer of antivirus and spam protection to SecurityGateway, and has been discontinued. When upgrading to v.3.0 the installer will inform the user that it must automatically uninstall ProtectionPlus before proceeding. Please note that if upgrading from within the web interface, there is no opportunity for a prompt and that ProtectionPlus will be automatically uninstalled.

Kaspersky AntiVirus integration, which was previously provided via the ProtectionPlus add-on, has been replaced with CYREN AntiVirus, which is now built into SecurityGateway.

Dynamic Screening Updates
Dynamic Screening for failed SMTP authentication attempts now works across sessions over time. Previously, the failed authentication attempts had to occur within a single session. The failed authentication count for an IP is reset at midnight, or when it is blocked and added to the Dynamic Screening list.

New User Verification Source Options
A “User Verification Source Options” page has been added, with options that allow response caching and user re-verification to be configured.

Message Log Filtering Updates
When viewing the message log, administrators can now select “Released” as one of the search criteria.

Attachment Filtering Updates
Exclusions can now be configured for attachment filtering. You now have the ability to exclude whitelisted senders, authenticated sessions, and domain mail servers from attachment filtering.

Added “Spam” and “Not Spam” Buttons for Bayesian Learning to the Quarantine Views
Messages in the quarantine can be fed to SecurityGateway’s Bayesian learning system to improve the spam fitler’s accuracy in detecting spam and non-spam messages.
