That's great to hear :) My only problem is that I think that there needs to be "something" inside postfix that prevents postfix from rejecting a mail, beofre it was checked against DWL/DKIM. So this is, where I think the milter comes and where the smtpd_restrictions need to be shifted to smtpd_data_restrictions. Could it mean that it might be enough to run amavis not as smtpd_proxy_filter, but as milter; maybe? Could this be a solution? Thanks Christian
