Oh blimey, you know how sometime you can do things because you think 
they make no difference, but you kinda forget it by the time you come to 
test things and then wonder why it all goes a bit pear-shaped?  I 
certainly do.  Very well, in fact.

Sorry to bother any/everybody, suffice it to say that the problem was 
with this particular user and nothing else. 

For what it's worth, I shall never again think that commenting out the 
"use_bayes 0" in spam.assassin.prefs.conf is a good idea.  Any mistaken 
belief that this would have no effect will never again enter my mind.
