I did not say that postfix would be a mistake :)
The log also shows that the "warning: numeric domain name in resource data of 
MX record for bond.com: 0.0.0.0"

I want solutions not only in this case in particular, but all similar cases.

All DNS admin can not speak one at a time when there is an error.

But I want to avoid mail loop.

MAILER-DAEMON in this case would be sent mail back to the bond.com (mail was 
probably SPAM).
Thus, deleting the mail queue was permitted.

There mail.bond.com entry in the DNS.

Thank you for your answer.
