[exim] routing based on IP that submitted message

Hi,

I have a requirement to have all mail that exim
accepts from a specified set of IPs, sent to a
specific remote email address.

I think what I need is a redirect router with a
condition to check the connecting IP against a
file, and then grab the dest email from the file.

File would be something like:

1.2.3.0        user@???
2.3.4.0/24    user2@???

Has anyone done this already? I'll probably dig
through docs more this afternoon, hoping someone
has a config snippet they can paste that I can
reuse.

Thanks!

Dave
