Firewall

Firewall

A programme or set of programmes designed to keep unauthorised users or messages from accessing a private network. The firewall usually has rules or protocols that authorise or prohibit outside users or messages. In email, a firewall can be designed so that messages from domains or users listed as suspect because of spamming, hacking or forging will not be delivered.
