I'm also got "WARN' in category of "Mail server host name in greeting" of dnsreport
"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.
mail.mydomain.com claims to be non-existent host server1.theserver.com:
220 server1.theserver.com ESMTP Postfix"
Can someone help me identify this errors and how to get my email working?
Thank you very much
