we need to configure a groupwise 8 system to deliver all mails to the local domain, but at the same time to a foreign domain.

So, for example, a mail to user@gwdomain.com should be delivered to both user@gwdomain.com but also to user@otherdomain.com.

Am trying to find the easiest way to set this up. I could use native forwarding, but that means I have to do create a rule for each user individually.

Does anyone know a way to enforce this system wide?

Thanks a lot.
