bounce back to the sender in first attempt.I don't want build queue on
server of such type issue mail.
Please suggest How I can Achieve this on postfix ?
it would be plain stupid to bounce in case of a *temporary* DNS error
a domain don't need a MX record at all, it would fallback to the
A-record, if the destination domain has a DNS problem it don't matter
