In Exim 4, this should be easy -- insert an 'accept' statement near
the top of the ACL controlling RCPT (the one named in the setting of
'acl_smtp_rcpt'). Be sure to restrict this 'accept' on
e.g. senders address and sending host.

Make sure this change does not change your Exim into an open relay.
This can e.g. be tested by doing "telnet relay-test.mail-abuse.org",
as mentioned in Exim's documentation.
