Whoops, you're perfectly right. On a system where spamc is run as some
fixed user (e.g. nobody), you need the -u option to get the per-user
options to work correctly. If spamc is being run as the receiving user
already (e.g. via procmail, barring some weird setuid behavior) then you
don't need the -u option (although it won't break anything if you use it,
it's just unnecessary).
Sorry for the incomplete info.
