[Exim] exim autoreply question

There is the following scenario what needs to be done. I have couple
of domains what I want to remove from service:

    @old-domain-1.com
    @old-domain-2.com
    @old-domain-3.com

and leave only one

    @new-domain.com

These are all 'local_domains' so I want to make the following trick.

In case if anyone sends mail to user@old-domain-[1,2,3].com I want
message to be delivered to specified recipient (at specified domain)

    AND

send autoreply to sender for example 'Your message has been delivered
to recipient user@??? BUT domain expire soon, please use
address user@???'

Thanks for any assistance
