Up to now I have been using the same access file for: check_client_access in smtpd_mumble_restrictions and postscreen_whitelist_networks.
since the client ips I had whitelisted for smtpd would also be whitelisted for postscreen (in particular this whitelisting is used to avoid DNSBL checks on specific IPs). I noticed that postscreen_access_list requires a permit action rather than an OK action in order to whitelist, so I will now need to duplicate the access file and change the action (that can be automated). Is there an advantage in having postscreen_whitelist_networks use permit action instead of OK as for other access lists? thanks John
