Greylisting whitelisting entries

So I'm updating my greylisting rules, and I'm trying to add gmail stuff. When I look at their SPF records, the amount of IP addresses (and ranges) is staggering. Does the whitelist table support a range of IP's - ie - 127.0.0.1-127.0.23.1? Or do I need to list each class C with a wildcard - ie 127.0...

David, Have you tried setting your limit a little bit higher? An email that's within 300k of being over seems to be a pretty poor test. Set your limit to 25mb, see if the message goes through.
