TESTING ======= First you have to create a ruleset (see Configuration section). Check it with postfwd2 −f /etc/postfwd.cf −C There is an example policy request distributed with postfwd, called ’request.sample’. Simply change it to meet your requirements and use postfwd2 −f /etc/postfwd.cf For network tests I use netcat: nc 127.0.0.1 10045
