Rem acu tetigisti.  You can't expect to do that successfully, any more
than you can run a car without using the steering wheel.  Especially
with geometric-mean Robinson, adjusting the spam_cutoff level to the
actual mail population is crucial.  Robinson-Fisher is said to be less
touchy, but I'm using 0.952 in my implementation of that because it
works better than 0.95 in my production system.

Dunno what it would mean.  There's no such thing as "a mail" even
though there's "an email."  So how can there be mails?
