   In any case, surely this check would be optional.

I hope not, then it makes rmail not usable for most users.

What is wrong with using real local variables?  Either by adding it to
the first message, or always adding "-*- rmail -*-" to X-RMAIL-...?
That way a user could disable rmail explictly for a file, or enable it
by adding -*- rmail -*- to it.  This would then work exactly as it did
for RMAIL/BABYL.  Without adding specifc rmail hacks to other parts of
emacs.
