We have hosted example.com domain in our email solution. now one of this domain's client which have domain test.com tried to send mail to example.com FIRST TIME. they recevied below error message in falire mail delivery :
addr=<firstname.lastname@example.org>: This domain's DNS violates RFC 1035.
That means the DNS entries w.r.t the mail server of example.com has to be correct for proper mail exchange.
