Dman,

Thanks very much, this is what I was thinking. The other website uses a
strategy where one Linux system does all the mail and functions as a POP
server for the other systems, it uses a single 'real' email address with
different Real Names to leverage multiple email accounts out of a single
address. 

I'll keep plugging at the exim docs: I _think_ that what you've outlined
above just means that exim will field an IP address as well as an MX
domain name. My understanding (incomplete) is that I could go with one
of two strategies:

1. Define my local network (192.168.1.0/24) as a local domain. Mail for
this domain wouldn't get sent to the smarthost defined in the ROUTER
configuration, but I'd have to set up something in the DIRECTOR
configuration to send messages to local systems.

2. Set up a ROUTER agent listed above the smarthost routine that checks 
the email domain name/address against a specific list of local systems 
or domains. If matched, it goes to that machine. Otherwise the email 
gets fielded by the smarthost routine.

But I think you're right 'real internet site's are the way to go.
Ideally, I'd like the two local systems to exchange mail automatically, 
both set up the same way.

Thanks, Paul
