# Script for blocking IPs which have been reported to www.badips.com
#   via ipsets.
#
# - THIS SCRIPT DOES NOT BLOCK ANYTHING -
# This script only updates ipsets with applicable data from
# badips.com. Actually blocking the ips in that ipset is left
# up to the user (so that you may do so however you prefer).
#
# Additionally, this script does not persist the ipsets through

mgaulton

# so recently I had an issue where I wanted to send email sent to a local user root (from logwatch, e.g.) to a different email address
# simple enough -- just add a ~root/.forward file, with the contents [email protected]
# all the email gets sent there...
# but the email shows up with a to: header of [email protected]
# what I really want is the to: header to be [email protected]
# so I can filter emails, etc...  below is how to do that.

#uncomment the following line in /etc/postfix/main.cf
#header_checks = regexp:/etc/postfix/header_checks
