Unlike a client access table, a hash mynetworks table needs to list the entire IP, not just partial octects or a netmask. I think the docs are clear on the format required, but one must read carefully so as to not confuse the syntax with an access table, or with the supported plain text file format. # mynetworks hash table format # list each IP on its own line 2.3.4.4 Anything 2.3.4.5 Anything 2.3.4.6 Anything ... A cidr table makes more sense than a hash for mynetworks since you can list network/netmask rather than listing each individual IP. But for most sites (assuming localhost + a couple local network ranges), just listing the networks in-line in main.cf is easiest. -- Noel Jones
