8 Introducing Symantec Mail Security for SMTP

Functional overview

Functional overview

You can deploy Symantec Mail Security for SMTP in different configurations to 
best suit the size of your network and your email processing needs. 

A Symantec Mail Security for SMTP host can be deployed in the following ways:

Scanner

 – Deployed as a Scanner, a Symantec Mail Security for SMTP host 

filters email. Your installation can have one or many Scanners. Symantec 
Mail Security for SMTP runs alongside your email or groupware server(s).

Control Center

 – Deployed as a Control Center, a Symantec Mail Security for 

SMTP host is a Web-based configuration and administration center. Use it to 
configure and manage email filtering, SMTP routing, system settings, and 
all other functions. Your enterprise-wide deployment of Symantec Mail 
Security for SMTP can have multiple Scanners but only one Control Center, 
from which you configure and monitor all the Scanner hosts.
The Control Center provides status for all Symantec Mail Security for SMTP 
hosts in your system, system logs, and extensive customizable reporting. 
Use it to configure both system-wide and host-specific details.
The Control Center provides the Setup Wizard, for initial configuration of 
all Symantec Mail Security for SMTP instances at your site, and also the 
Add Scanner Wizard, for adding new Scanners.
It also hosts the Spam and Suspect Virus Quarantines, for storage of spam 
and virus messages respectively. End users can access the Control Center to 
view their quarantined spam messages and set their preferences for 
language filtering and blocked and allowed senders. Alternatively, you can 
configure the Spam Quarantine for administrator-only access.

Scanner and Control Center

 – A single Symantec Mail Security for SMTP 

host performs both functions. 

Note: 

Symantec Mail Security for SMTP provides neither mailbox access for end 

users nor message storage; it is not intended for use as the only MTA in your 
email infrastructure. 

Note: 

Symantec Mail Security for SMTP does not filter messages that don’t flow 

through the SMTP gateway. For example, if two mailboxes reside on the same 
MS Exchange server, or on different Exchange servers the same organization, 
messages will not pass through Symantec Mail Security for SMTP filters.
