Is it possible to let greylist take the subnet of a sending email server into account. For example other vendors support "Netmask for GreyListing"

When one gmail server is sending mail form 1.2.3.x and get`s greylisted the same email (5 minutes later) wil be accepted from 1.2.3.y because they are all part off the 1.2.3.9/24 subnet for example. The /24 of /20 should be configurable

I think the greylist figures this out automatically after a few emails arrive, but I'll have to take a closer look.
