I don't know; I am not familiar with that option and have found no
good documentation on it.

It is a compile-time option for elm. I can compile Elm to
automatically encode into quoted-printable if this would be best for
compatibility with mailers not as featureful as sendmail.
(BTW, I thought smail and Exim were command-line compatible with
sendmail?)
The bug report that I originally received said that messages with
high-ASCII characters were being sent without any warning of failure.
It appears that Exim will just ignore any messages with -B8BITMIME
with no warning at all! BAD!
