I don't use emacs for email, but apparently its mail reader uses the emacs
"enable-local-variables" feature. And, apparently, some mischief can be
done by this mechanism. This feature is disabled with
    (setq enable-local-variables nil)
    (setq enable-local-variables 1) 
The later causes it to query you if local variables exist.

Perhaps someone on the list is more familiar with this issue and emacs
