Do you have logs? Are there frozen messages in queue? Does the box have
information for a default router - some pointer to a name server or 'search...'?
For the chron jobs, you may need nothing more complex than aliasing 'root' to a
valid off-box address, (or at least local non-root address), as Exim is normally
defaulted to not run as, or deliver to 'root'.

It may well be already so defaulted.

Check and see if they do not already have an instruction that covers at least
the need for a valid 'alias' entry.
