Hi.

I often see this in logs:

> Your message to the following recipients cannot be delivered:
>
> someone@sub.domain.yy:
> <<< This domain's DNS violates RFC 1035

The nslookup set type=SOA on the same has following:

Authoritative answers can be found from:
sub.domain.yy nameserver = xxx.xxx.xxx.xxx
sub.domain.yy nameserver = xxx.xxx.xxx.xxx
sub.domain.yy nameserver = sub.sub.domain1.yy
sub.domain.yy nameserver = sub.sub.domain.yy
sub.sub.domain1.yy internet address = xxx.xxx.xxx.xxx
sub.sub.domain.yy internet address = xxx.xxx.xxx.x

set type=MX has following:

Non-authoritative answer:
sub.domain.yy preference = 30, mail exchanger = mx.sub.domain.yy
sub.domain.yy preference = 20, mail exchanger = xxx.xxx.xxx.xxx

How to get mails delivered to such domains from server which doesn't deliver on account of RFC 1035 violation of destination dns record?
