[Pkg-exim4-users] Redirect-router, working but not clean!?!

[Mario Wolff]

Dear list,
i got my problem solved, but i think it's not clean and not in a way
it should be solved. Hope someone can hint me something!

What i want:
I have two domains, let's say foo.org and bar.org. For bar.org there
is a MX-Record that points to a groupware-server witch handles ONE
domain. Foo.org is handled by my exim4. Both domains should be handled
in the same way, same name with diferen tld's.

What i have done:
Placed foo.bar in dc_relay_domains, put
> *@* ${lookup{${domain}}lsearch{/etc/exim4/dom-shadow}{${local_part}@${value}}fail} tT
to rewrite section of exim4.conf.template and
> foo.org: bar.org
to /etc/exim4/dom-shadow. With this settings my exim works like i
want. But is that clean? Ist there a more straigt-forward-way?

Thanks for hints!

Regards,
Mario
