OK, so I've been bad at keeping up with messages....

Yes, indeed.
Milter-greylist with the "lazyaw" setting will do exactly what you
describe.
Basically, the first time sender/recipient/IP gets greylisted, but when
they succeed, "lazyaw" causes the IP address to be whitelisted instead
of the tuple. Combining that with "subnetmatch /32" and "autowhite
40d" would do exactly what you said.
I suspect that anybody using "lazyaw" would want to change the
"subnetmatch /24" default because whitelisting 256 IPs because just one
retried would be a bit too much, I think.
