In brief, if I chose 'satelite', to get exim4 to consider any mail local
I need to manually add in this kind of thing:

dc_other_hostnames='chianti.cogweb.net'

Is that correct? So that means it's a local address?
That's really not self-explanatory. I added this,
borrowing from exim3 a more explicitly named variable:

dc_local_domains='localhost:chianti'

That seems to work, but I haven't tested if this line is what makes
the difference. Which one do I really need?

The fact that there's no universal default configuration is
a given; it's still useful to suggest a commonly valid default.

If I use the FQDN, will exim4 still understand this is to
be treated as the local machine? Where the mail appears
to originate isn't much of an issue for me; I'm not
receiving mail from the outside in any case.

Interesting -- but only after manually adding local machines,
right?

I see -- so this is pain inflicted by a delayed sarge?
