I don't know. After whitelisting Google's SPF record (which includes
something like 70,000 /24 address blocks), I didn't feel so ambivalent
about whitelisting AOL's server list.

With whitelisting, one has to hope that the odds are in favor of the
whitelisted IP or IP range remaining free of spam-bots. In general,
for addresses assigned to mail servers, this is likely to be the case.
I realize this breaks the generality of the greylisting, but does not
appear to have a measurable impact on the overall effectiveness.
