What is the definition of "sender" concept for Exim (3.16)?
Speaking more precisely, what does Exim try to lookup in the DBs
specified in "sender_reject" clause? It does not look like the
address extracted from "^From:" field. Is there any way to make this
lookup based on "^From:" field avoiding to use filters?
Thanks!
