delivering by domain to separate cyrus servers

Hi,

I'm using sendmail to deliver via LMTP to a cyrus backend running on
another host:

sendmail.mc:
------------
MAILER_DEFINITIONS
define(`confLOCAL_MAILER', `cyrusv2')dnl
define(`CYRUSV2_MAILER_ARGS', `TCP mail01.server.de 2003')dnl
MAILER(`local')dnl
MAILER(`smtp')dnl
MAILER(`cyrusv2')dnl
------------

For a single domain I'd like to deliver incoming emails to another cyrus
server, eg. mail02.server.de. How would I do that?

Ciao
Marcus
