I'm afraid there are several research projects hiding in there, so we'll
probably never know. For an individual, SpamBayes does much better than
chance after training on 1 ham and 1 spam, and even just that much can
*help* keep your inbox saner. If a single SpamBayes was trying to filter
email for several people, though, it may even do worse than chance after
training on 1 of each (don't know -- haven't tried; "head arguments" can be
made in any direction here; for example, if the single spam trained on was
addressed to me, and the single ham to you, then there's systematic pressure
to call everything addressed to me spam, and everything addressed to you
