You're right. What I was thinking of was a distinction between
"the buck stops here, where do I set this thing?"
and
"this ain't mine, you take it"
messages. In my mis-terminology above the former is "incoming" (exim3
director) and the latter is "outgoing" (exim3 router).

Ok, right. I can say "if the recipient is here (my domain) then see
if it meets the other conditions" and "if the recipient isn't here,
check the other conditions" to achieve what (I think) I want.

I'll look for it.
