Anti-spam appliances

From Wikipedia, the free encyclopedia

Deployed at the gateway or in front of the mail server, anti-spam appliances are hardware devices integrated with on-board anti-spam software and are normally driven by an operating system optimized for spam filtering. They are generally used in larger networks such as companies and corporations, ISPs, universities, etc.

Reasons anti-spam appliances might be selected instead of software could include:

• The customer prefers to buy hardware rather than software
• Ease of installation
• Operating system requirements (e.g. company policy requires Linux, but software is not available under this OS)
• Independence of existing hardware
