I guess what it comes down to is that you have to weigh your confidence in the system that you'd be allowing to relay against the annoyance to your user of opening him/her up to _all_ the spam that comes down your pipe. This is definitely something that has to be considered on a case by case basis. As has been hinted at by everyone in this discussion, probably the safest thing to do is to ignore the Bigfoot issue and encourage the user to use an e-mail provider that does not choose to locate their servers in a widely-blacklisted part of the 'net.
One other possibility is to provide that user with a separate whiteholed address that they use for their Bigfoot correspondence.
I do something similar with several of our clients who are always jetting off to (or corresponding with people from) spam crazy places like China and Brazil.
