While I'm fairly well aware of the size of your operation, the specific
implementation (1) I'm looking at here does scale fairly well. At least
well enough for my setup here, which is anything but a single box. ;)

Again something this implementation is trying to avoid by design.
Aside from the little detail that greylisting, like all other spam
avoidance options here, is just that: a per user option.
Grief to spammers is something like teergrubing, they suffer a bit, but
the spam gets thru eventually. Whereas with greylisting the chances of
it never making it through are quite high, so that qualifies more in the
"hurting" department in my book.
