It's intersting that google says to use ~all. This should not stop any spoofing at all, for servers that are following the openSPF standard. I guess if google isn't following it, then it may work for your situation, but may not for users outside of gmail that are receiving these spoof emails. Another option I thought of is to block the offending IPs explicitly by adding:
-ip4:192.168.1.15/24 Would tell servers that honor the SPF to not allow emails from that IP range. -John Shaver /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
