# This is a test configuration. It listens on port 8025, waits for an incoming
# connection, and applies the following rules :
# - if the address is in the white list, then accept it and forward the
# connection to the server (local port 25)
# - if the address is in the black list, then immediately drop it
# - otherwise, wait up to 35 seconds. If the client talks during this time,
# drop the connection.
# - then accept the connection if it passes all the tests.
#
# Note that the rules are evaluated at every new chunk of data read, and at
# delay expiration. Rules which apply to incomplete data don't match as long
# as the timer has not expired.
