That is a bit problematic, those are separate email accounts.

In such case I think it is preferable to limit hacks with
$spadroot and mostly use FRICAS environment variable.
AFAICS orignal purpose of $spadroot was to allow some
limited testing/use without setting envirionment. It
still helps with testing so I prefer to keep it, but
in normal use we should depend on FRICAS being set.
