Your solution (reject mail from hosts that does not have reverse) totally wrong.
Why? Ex: at least 1/4 of hotmail's emitters does not have in-addr.arpa records.

No, you can fix this problem by this way:
host_reject = /usr/exim/tables/IP_CONN_REJ : +allow_unknown :\
partial-lsearch;/usr/exim/tables/HOST_CONN_REJ
First file contains only slashed network addresses (presense of reverse zone
does not matter), second file contains FQDN's. +allow_unknown inserted between,
signalyze to accept mail from hosts without .in-addr.arpa records.
