Understanding system requirements

Hardware and software requirements

Browser

A secure Web connection using one of the following browsers:

Microsoft Internet Explorer 6.0

Firefox 1.5

Foldering 
Support

Spam Folder Agent: 

Exchange 5.5, Exchange 2000, or Exchange Server 

2003

Symantec Spam Folder Agent for Domino: 

Lotus Domino 5, 6, or 6.5

Exchange foldering using Spam Confidence Level:

 Symantec Mail 

Security for SMTP must be installed on an Exchange Server 2003 
server. Exchange Server 2003 must be installed on the back-end 
message store. Users must enable the Junk Mail Filter in Outlook 2003 
or Outlook Web Access 2003.

Note: 

Foldering agents must reside on machines running their 

corresponding message server; they cannot run on machines which 
also run Symantec Mail Security for SMTP. 

Privileges and 
permissions

For installation:

 You must be an administrator of the local computer 

to install any Symantec Mail Security for SMTP component on that 
computer.

After installation:

 The subfolder where Symantec Mail Security for 

SMTP is installed and its subdirectories are created with the default 
permissions relative to their location. If security is a concern, and 
since the configuration file is accessible via the network, it is 
recommended that you verify that the permissions are acceptable after 
installation, and modify them if necessary. Ensure that at least local 
administrators retain full access to everything, so that the various 
system components can continue to function properly.

Service Permissions:

 Except for the Spam Folder Agent, Symantec 

Mail Security for SMTP Services run as the Local System Account, 
which gives them full access to system information and resources. 
Should you wish to change this, it is imperative that the services run 
with a user belonging to the local administrators group. You choose the 
account that the Spam Folder Agent runs as.

LDAP

Necessary if you want to have LDAP-based group policies or alias 
expansion.
