Okay... Here goes...

I haven't touched configuring exim for a while, because last time I
tried to set the thing up in the basic local mail plus outbound via my
ISP, ALL my mail started being sent via my ISP. I'm guessing I just
mis-understood a term or an option...

Ultimately, I want mail without a domain, or with mydomain or
mydomain.localnet (in either the from OR to fields of a message), to
remain local. Mail originating from this system with a particular
domain in its from address, should be delivered via the relevant mail
server for that domain (eg. my.name@my.isp.com should be sent to
my.isp.com for delivery), or bounced if I don't have a mail relay
reconfigured for that domain.

I'd think this should be a fairly basic setup, but I can't for the life
of me sort through all the similarly named options to figure out which
ones I should and shouldn't use. :(
