    I have to servers with ispconfig perfect setup ubuntu, all works fine, it's an excellent software, only one warn detect on dnsreport:

    WARN Mail server host name in greeting WARNING: One or more of your mailservers is 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). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.

    exemple.com claims to be non-existent host server.example.net:
    220 ramserver.grupaprop.net ESMTP Postfix (Ubuntu)

    I'm reading some posts, I'm looking for a solution, Thanks.
