Using the Email Security Service

The email security service in Enforced Client Advanced scans messages before they are received 
by client computers and quarantines detections. Your service checks for spam, phishing scams, 
viruses, directory harvest attacks, and other email-borne threats in messages and attachments.

The email security service resides outside your network, requiring no system resources. Your 
company’s mail exchange (MX) record is redirected through SonicWALL’s servers. There, your 
email traffic is scanned before entering your network, with less than a one-second delay in 
transit. 

The email security service provides: 

„

Protection from email-borne threats — The flood of email threats is stopped before 
entering your network.

„

Real-time, around-the-clock email security — Email is processed all day, every day in real 
time through a highly secure system architecture that operates with no detectable latency. 

„

Simplified management — Centralized, web-based policy management allows you to 
configure comprehensive policies for spam, viruses, and content-filtering (for inappropriate 
words and phrases). You can also view reports on email usage and check quarantined 
messages. 

To use the email security service, your company needs to have its own mail domain, such as 
yourdomain.com, with a static IP address and a dedicated email server, either in-house or hosted 
by an ISP.
