What do we check in the domain, just that it belongs to us?

Yes, that's precisely what I want. Technicaly it's a reject, just with a
particular code (551).

Ok, I'll try to do it this way. Is there any documentation around for the Exim
config file interface? In particular, does ${readfile} support proper parsing?
(remove # comments, trailing newlines, empty lines, etc)

Could you give me a reference to these items? I'd help with them if I can.

I was thinking of users (those who know what .redirect means, of course). For
sysadmins, we could have the same syntax extension for /etc/aliases that
Sendmail does (see my other mail about this, in this thread).
