What configurations are necessary for e-mail using personal networking devices and the Symantec Brightmail Gateway appliance?
With an ever expanding list of devices that are network aware and can send e-mail, it is important to understand how the Symantec Brightmail Gateway interacts with these devices.
Essentially, the Brightmail Gateway appliance only monitors e-mail traffic using the Simple Mail Transport Protocol (SMTP), any other traffic should not be routed to the Brightmail Gateway appliance (see below for a reference list of protocols used for e-mail traffic). The protocols other than SMTP are generally internal protocols and are not usually used for transmitting e-mail traffic from an internal Mail Transfer Agent (MTA) to an external MTA.
For devices that use the SMTP protocol, the SBG appliance version 9.0.0 and higher allow for the authentication of email clients to relay messages. This allows the email client of a personal networking device to connect to the Symantec Brightmail Gateway appliance to directly relay messages after authentication, avoiding the need for the client to communicate directly with the internal mail server.
More information on the usage and configuration of the Authentication Mail Settings, review the context sensitive help in the Control Center GUI:
1. Click on Administration. 2. Click on Configuration. 3. Edit a scanner host. 4. Click on the SMTP tab. 5. Click Help. 6. Scroll down to the section: Edit Host Configuration - SMTP Authentication Mail settings.
The Brightmail Gateway version 8.0 and prior do not have this feature. Upgrade the Brightmail Gateway software if this feature is necessary.
For information on requirements and configurations of personal networking devices, contact the vendor of the device.
The Symantec Brightmail Gateway can also handle Instant Messaging (IM) traffic, but does not currently support mobile IM clients. For general information on IM clients, the Brightmail Gateway, and IM Manager, please review the Administrator Guide and refer to the following Symantec Knowledge Base article:
