How strange. By signing sender address it's trivial to separate real
bounces from bounces of joe-jobs, and in fact to reject the latter
(hence also preventing the potential _recipients_ of joe-jobs from ever
accepting the mail in the first place, if they bother to do CBV.
BTW, we have to do the SPF check on the first server, otherwise we don't
have the correct IP.
