Re: Transport question

i think you could also create a virtual-alias-map like this:

this.user@foo.com -> this.user@groupwise.foo.com
that.user@foo.com -> that.user@groupwise.foo.com

you don't mention the exchange-users so they take the normal transport-way

and the new transport-map looks like this:
groupwise.foo.com smtp:[groupwise-ip]
foo.com smtp:[exchange.foo.com]
