That's a thought. The rule would be "If exim is called with -C or -D by
non-root/non-built-in-exim, causing it to give up root privilege, and
then if after reading the configuration file exim_user is set to the
calling user, implying that it should be privileged after all, then
panic."

As it happened, in the particular case that caused this, it did all work
without privilege (apart from a problem with logging, which I have now
fixed) because it was just doing remote deliveries, but in general one
shouldn't rely on this, so I think that preventing it is probably a good
idea.
