IP addresses to /etc/hosts.allow to block further access after a specified number of attempts.
|Unix||PHP||This small program compares local-host-names to the Sendmail virtmap table and alerts the user of any domains that do not have a "catchall" alias defined.

Syntax (from shell): ./check_catchalls (no options)
