Exactly. So is there anything you can think of to thwart someone who uses a technique like that to learn a user's whitelist contents? It seems like most
spambots can't usually be bothered to have a list of acceptable FROM addresses for each destination address, so I think it'd have to be a situation where it'd be more
like a harrasement case than just spam. But aside from guessing about intent, what are the good measures to take against forged FROM addresses that happen to be on a user's whitelist?

Well, you could implement SPF, et al, in your MTA but that's not a job for maildrop and that would only work for those domains publishing SPF (or whatever) records.
