secondary server must be identical to the primary and will only be used when the primary server is not available.
• Customizable Delivery Status Notification (DSN)
Customizable Delivery Status Notification (DSN) allows users to customize both transient and permanent notification
emails. Users can customize the body, subject, and sender fields of the email. For transient DSNs, users can customize
the interval at which DSNs are sent.

Important Note for McAfee Anti-Virus Subscribers
Upgrade McAfee to Engine 5400 McAfee will be ending support for the anti-virus scan
engine v5300 (running in SonicWALL Email Security
versions 7.1.2 and lower). SonicWALL Email security
customers using McAfee antivirus will need to
upgrade their email security firmware by
February 28th, 2010.

McAfee has released an upgraded version of their anti-virus engine using a newer, enhanced format that provides smaller, faster
signature updates, improved bandwidth, and better detection of the latest malware. As of February 28, 2010, SonicWALL
McAfee anti-virus engines in the firmware versions 7.1.2 and lower will no longer receive virus signature updates. Customers
using McAfee anti-virus will begin to see degraded virus protection and will no longer be protected against the latest virus
Customers can simply upgrade their SonicWALL Email Security firmware to receive the benefits of the McAfee upgrade. The
impact will be largely transparent to administrators and end customers. To ease the transition, SonicWALL will offer customers
the following upgrade path:
• Upgrade to SonicWALL’s newest, latest firmware (version 7.3.0). In addition to the enhanced SonicWALL McAfee
engine, firmware version 7.3.0 offers several significant enhancements, including best-in-class effectiveness,
bandwidth improvement, improved ease of management and significant scalability improvements.
