I would need a policy service for that (correct me if i'm wrong). So if I wanted to do this check I would need an smtpd + policy service and the policy service would need to do the exact same lookups in order to get a combined score and make a descision based on that. I think it's a lot of overhead where one or two pcre checks would suffice. If I create a patch, could this feature make its way into postfix? Jeroen
