[EXIM] Rewriting for not-local_domains

Hello together,

for an intranet mailserver I want to do rewriting only if the
recipient is not in the $local_domain.

*@intra.net \
{if recipient is not in $local_domain} user@??? \
Ffs

Is this possible and how do I have to write my rewriting rule?

Many thanks,
Andi.
