"Smarthost" should work for you as well, if configured correctly.

Experience has shown that it is not a good idea to nudge people
towards some choice, since there are always configurations in which
the "default" choice won't work. This actually is something we have
learned from exim3 nudging people towards the "internet" choice, which
will fall in pieces in a firewalled setup where usage of a smarthost
is absolutely mandated - for example in most corporate environments
and on ISP networks employing port 25 blocking.

In your case, yes.

"This name will also be used by other programs; it should be the
single, full domain name (FQDN) from which mail will appear to
originate." "chianti" is not a fully qualified domain name. This is
one of the first changes that will be done to the Debconf templates
once the strings have been unfrozen after sarge's release.

No, satellite is fine.

Your problem was that you didn't configure any local domains, hence
all mail was considered non-local. I tried to explain that in my first

Mail is - unfortunately - a little more complex than your average core
package, and the debconf templates have been frozen for too long time.

We are open to your suggestions.

May I suggest that you trim down your quoting to what you really are
