mailertable feature in exim/Vexim

Dear List Members

I had been pondering about this issue for the last few days, and even
though i went through the documentation and google, I could not find any
reasonable solution to it.

Those who know sendmail well, are aware of the mailertable feature.
basically it is a mapping between domains and destination servers. for
example, in the mailertable file if I write

test1.domain.com      esmtp:x.y.com
anotherdomain.com      esmtp:[192.168.1.1]

and so on, then the mails destined to those domains will be handed over
to the respective servers. The benefit is, if you have several hosts
housing the mailboxes for particular domains, you can hand over the
mails directly without needing any dns server running.

For elaboration, let us imagine a scenerio of a multi-office but common
mail gateway to the internet. The server that catches all emails
destined for multiple domains, after content and virus checking, it
hands over the mails to the respective servers. It does not consult any
DNS server for MX records, just hands over the mails to respective IP
addresses.

I was looking for similar option for the relay domains. It would have
been better if I could set up the functionality -- even if *not* through
vexim, but if that can be done via exim then it will be great.

Any pointer / suggestion / link is highly appreciated

Thanks.
