Pkg exim4 users - Nov 2006 - Redirect-router, working but not clean!?!

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

In my opinion, it is as clean as it is possible in a setup as sick as
this.

Maybe a simple redirect router (redirecting mail for the one domain to
the other domain while retaining the local part) would be enough as a
MTA is supposed to look only at the envelope and not at the headers.

I didn''t bother to think more about it since your intentions are not
worded very clear and you made understanding your wishes even harder
by (a) obfuscating (see
http://www.exim.org/eximwiki/MailingListEtiquette#head-a6f7fb5ce8816568569a321f783315207ec38063(
and (b) mixing up your obfuscation later (foo.bar is not defined
anywhere, you defined foo.org and bar.org, abusing other people''s
domains in an attempt to solve your spam problem)

Greetings
Marc
