[Exim] Forcing mail through with an MX set as an IP....

Hello all,

Is there a way to set exim up to force mail through when a particular
domain has their MX record pointing to an IP address instead of a host?

This is the return message that is recieved when trying to send mail to an
MX record set up to point to an IP address instead of a domain:

all relevant MX records point to non-existent hosts:
it appears that the DNS operator for this domain has installed an
invalid MX record with an IP address instead of a domain name on the right
hand side


Thanks,
Mike
