<<The configuration of your mail servers and your DNS are not ok! The report of the test is:

    mail.mydomain.com. -> mydomain.com -> 78.47.63.148 -> static.148.63.47.78.clients.your-server.de

Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server.>>

I have a A Record that points mail.mydomain.com to 78.47.63.148 (which is my given ip address for my vps) All other records are fine, so what's wrong and what record should I create to make it right? Thanks
