[Exim] Re-write Question

I have a REAL address of the form:

user@???

and I want to accept mail to:

any_address@???

.. so I have the following re-write rule:

^.*@(.*).mydomain.com $1@??? SE

which works, but has an unwelcome side effect in that if, say, a mail
arrives which is addressed to user1@??? and
user2@???, exim re-writes the addresses, ends up with the same
address for both and delivers just one copy of the mail. Smart behaviour,
but is there any way I can wind up with both copies delivered?


Cheers
