# This is a simple ruleset to block all traffic from servers
# on the JabberSPAM blocklist. Even traffic from existing user
# contacts will be blocked.
#
# Example config (make sure "firewall" is in modules_enabled):
#
#   firewall_scripts = { "module:scripts/jabberspam-simple-blocklist.pfw" }
#
# For a more advanced ruleset, consider using spam-blocking.pfw
# and spam-blocklists.pfw.
