I'm pretty new here, but a quick google search suggests that perhaps
http://gking.harvard.edu/amelia (and maybe google translate)
might have some decent pointers for you.

I poked at the documentation from that site (a pdf file), and it's
quite intense on
the mathematics, you may get more from it than I could.  there's also
a link there
to a separate, for thisspecific package/algorithm  (it seems to be
called Amel ia II,
 I'm assuming this is the same that you used, if I'm off .. sorry about that)

Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
