EXPN wasn't on the wishlist, but I've made a conditional entry. I need a
bit more convincing of its usefulness. (And I haven't looked at how easy
or difficult it would be to implement.) It would obviously have to be
restricted to certain hosts or networks. I don't quite see how
"except_domains" and "except_local_parts" comes into it.
It seems to me that in most situations you want to keep the information
as to how a local part is processed private to the host that is doing
the processing. With an account on that host, you can find out what Exim
will do with an address by calling it with the -bt option.
