Hi,

today I added full IPv6 support and the amavisd-new bindings. Now it's possible to have dnswl.py used as policy-service in postfix and if it find a MTA on a whitelist, it automatically gets soft-whitelisted in amavis (using SQL).

I will put the new version on my side later on.

Have fun
Christian
