You are mixing up verify = sender and verify=sender with
callout. The former only checks whether exim could _route_ a mail to
this address (which succeds, foo@??? goes to mail3bb.sun.ac.za).
We cannot tell why the original message bounced at all and therefore
do not know if/why "verify recipient" should have worked.
