Aarrgghh!! What a horrible situation to be in. I am sorry, but I live in
a fully-connected world, and never considered such situations when I was
designing Exim. Using it in these kinds of cases is always going to be
messy because it just isn't built for that sort of situation.

Do you mean that there are some users who do not have world-usable
addresses? Surely there must be some valid world-usable domain for your
machine? If there is, can't all users just use that domain all the time.
You don't have to make any use of the host name. See qualify_domain.

No, but it is related. The "from " line in saved messages records the
envelope sender address, which is indeed used by MTAs for errors.
However, it is not transmitted as a "from " line in messages that are
sent by SMTP. The envelope sender is transmitted by the MAIL FROM
command.

Your mail domain must be a valid one if mail is to get to it from
outside. It doesn't matter what your host name is.
However, I may be misunderstanding what is going on here. How are you
receiving mail? I am assuming it is by SMTP, but if you are downloading
using fetchmail or something like that from a server for some other
domain, then it is a real mess and maybe what I am saying isn't
relevant. As I said, I don't pretend to cater for such situations.

The point is that a single message can be both remote and not remote if
it has several recipients. Therefore, in order to do what you want to
do, you have to split it up into two copies...

... and the FAQ mentions some ways that you can do this, but Exim isn't
designed with this in mind, so it is a mess.

It's no good trying to provoke me by mentioning sendmail. :-) I am not
trying to compete.
