[Exim] A simple question...

Hi all;

I can't send e-mail to this domain tecnicard.net, when i test the address
I have the following results:

sendmail -v -bt user@???
JMier@??? is undeliverable:
all relevant MX records point to non-existent hosts: it appears that the
DNS o perator for this domain has installed an invalid MX record with an IP
address in stead of a domain name on the right hand side

Is posible to send mail to this domain without change the DNS
configuration, and without no_forbid_domain_literals or the "user@[ip]"
format.

Thanks in Advance.
