    We go here http://dnsreport.com and run our domain and get a couple of warnings, wandering if anyone can tell us how to clear them up?

    First we get this one


    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.


    test.com's postmaster@[xxx.xxx.xxx.xxx] response:
    >>> RCPT TO: <postmaster@[xxx.xxx.xxx.xxx]>
    <<< 501 : domain literals not allowed


    Then we get this one.


    WARNING: One or more of your mailservers claims 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 is a technical violation of RFC821 4.3.

    test.com claims to be host server.nameofserver.net.

    You don´t need do something special for it. All is OK.

    The Warming: One or more of your mailservers claims to be a host other than what it really is ...

    You see this waring because you are using a shared IP (the IP of your server) for host all your domains.

    The other warning does not represent any problem.
