Yes, and the warning is telling you that the value '192.168/16' (not the the name 'internal_networks') is not duplicated in trusted_networks, as would normally be expected. 3.0.x docs say: > MXes for your domain(s) and internal relays should also be specified > using the internal_networks setting. When there are 'trusted' hosts > that are not MXes or internal relays for your domain(s) they should > only be specified in trusted_networks. As for why this linted OK before, couldn't tell ya. Haven't looked at 3.1.2 yet. --Sandy
