[Exim] using Exim to send all incoming mail to an M$ Exchang…

Hi all

It appears that I need to set this in the configure file:

(in the routers section)
lookuphost:
driver = lookuphost
transport = remote_smtp
ignore_target_hosts = 127.0.0.0/8
no_more
self = pass
domainlist:
route_list = * internal.server byname

Is that correct?

TIA
Peter
