The two new lines -- the Mail Security 8100 and the 8200 series -- will be available at the end of February, said Symantec, and aren't meant to compete with long-time partners such as IronPort, which sells its own appliances based on Symantec's software technologies.
The 8160, the only model in the 8100 line, will cut unwanted e-mail heading to corporate networks and Internet service provider in half, said Daniel Freeman, the product manager for the two new appliance lines.
"It will eliminate 50 percent of all [unwanted] incoming mail before it hits the gateway," said Freeman. The 8160, which is positioned at the network edge, is designed to reduce e-mail infrastructure and storage costs and trim administrative labor now devoted to managing the huge volumes of mail, most of which is spam.
"The 8160 filters at the TCP/IP level, not the SMTP level," said Freeman in explaining how the appliance shapes traffic flow by stopping spam on the spammer's servers.
