i suspect this is not configured to do as i expect. i am hoping to
respond to the sender with a 5xx if the user is not known
First, test it with "exim -bt" (maybe with -bh plus -d-all+acl+route).
To expand on that, "verify = recipient" just runs the routing chain to
discover if a routing decision can be made. The knowledge that a recipient
really exists lives there; if the recipient is local then a router that
deals with local deliveries should be also checking local_part, and
for external destinations the extent of knowledge is (usually) that
a target MX can be found in DNS (the remote MX is not contacted at this
time, unless you do a "callout" verify).
A "-bt" test also runs the routing chain.
