spamd greylisting, masking on /24

[Stuart Henderson]

I seem to remember seeing a patch to spamd that makes greylisting only 
look at the first /24 of the address, but I can't find it after fairly 
extensive searching with google/marc. Does anyone have a copy they 
could point me at?

The whitelists on puremagic.com (on which greylisting.org's lists are 
based) don't list networks with a common spool unless more than a /24 
is involved (there are some /24 listed with other factors requiring 
whitelisting, e.g. unique sender addresses per delivery attempt).
