ABSTRACT:
A method of blocking spam at a firewall involves applying blocking measures for an adaptively determined duration. The blocking measure is then suspended while determining whether the spam has ended. If so, the method resets to an initial state. Otherwise, the blocking measure is re-applied for a second duration.
