DNS & Mail Errors any guru's around
WARNING: Your SOA (Start of Authority) record states that your master (primary) name server is: ns1.myDNS.com.. However, that server is not listed at the parent servers as one of your NS records! This is probably legal, but you should be sure that you know what you are doing.
WARN - Multiple MX records WARNING: You only have 1 MX record. If your primary mail server is down or unreachable, there is a chance that mail may have troubles reaching you.
WARN Mail server host name in greeting WARNING: One or more of your mailservers may be claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). This probably won't cause any harm, but may be a technical violation of RFC821 4.3 (and RFC2821 4.3.1).
mydomain.com claims to be host nmx.myservername.com.
WARN Acceptance of domain literals WARN: One or more of your mailservers does not accept mail in the domain literal format (user@[0.0.0.0]). Mailservers are technically required RFC1123 5.2.17 to accept mail to domain literals for any of its IP addresses. Not accepting domain literals can make it more difficult to test your mailserver, and can prevent you from receiving E-mail from people reporting problems with your mailserver. However, it is unlikely that any problems will occur if the domain literals are not accepted.
mydomain.com's postmaster@[70.84.**.***] response:
>>> RCPT TO:<postmaster@[70.84.**.***]>
<<< 501 : domain literals not allowed
