Just a quick question since I have not found a way in my Googling. We are replacing some of our internal Exchange relays with postfix. Currently we have other internal postfix relays which utilize a client access file to allow relaying. The file contains all single IPs, no ranges.
The exchange servers have some groups of consecutive IPs on their allow list, some cover 5 or 6 IPs, others 100. Is there a way to provide the same list .i.e. 192.168.0.2-12 OK without: Listing them all individually i.e. 192.168.0.2 OK 192.168.0.3 OK Etc... Or Allowing an entire subnet 192.168.0.0/24 OK If not possible, that's fine, I will just list them by hand, just hoping there was a native way to do it. Thanks, Rich
