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. > I would not reconfigure postfix to work around bond.com's brokenness. > For one thing, that would be the start of a very slippery slope.

Thank you for your answer. -- [Varadi Gabor]
