[Exim] lowest numbered MX record point to local host

Hi all,
I got this error message :

18vPue-0007Ci-00 Unfrozen by forced delivery
18vPue-0007Ci-00 lowest MX record for mortgageleads.tv points to local
host
18vPue-0007Ci-00 == pamela_gold3@??? R=outgoing_mail defer
(-1): lowest numbered MX record points to local host
18vYXc-0008L4-00 <= <> R=18vPue-0007Ci-00 U=mail P=local S=506
18vPue-0007Ci-00 Frozen

How could I tell to exim to remove directly message from host where the
lowest numbered MX record point to local host?

Thank you
