[Exim] Accounting

Hi!!

I would like to have seperate remote_smtp-transports for each domain I host
to provide some basic accounting. I read something about the domains-option
for routers but doing something like

dom.ain-router:
driver = lookuphost
domains = dom.ain
transport = dom.ain_remote_smtp

and

dom.ain_remote_smtp:
driver = smtp

showed no success.

Any hint?

Thanks

Daniel
