Milter-greylist

DNSWL uses an unusual form or result code for the lookup. I do not want to whitelist on 127.0/16. I'd love to be able to whitelist say on:

127.0.X.3, or, 127.0.X.2. Unfortunately, I see no easy way to do that.

My thought is milter-greylist already support regular expressions for some acls. Maybe that can be expanded so they can be used for the result code of the lookup?

The only workaround I know of is to issue lots and lots of dnsrbl commands in the greylist.conf file, and also the corresponding racl commands for each X value. Which I suppose would work, just hoping for a better way.

BTW - the dnswl website says this:

"The milter-greylist developers work on a possibility to exclude only certain scores (the "x" in 127.0.x.y) from greylisting. Thanks to Greg Troxel for bringing this up."

However, I can find no discussion of this issue in my searches at least.
