This is saying you need some DNS records for your domain and your mail server. Your mail server needs matching forward and reverse DNS records, and it should announce itself as whatever you set the forward name as. If you are using NAT, this will be related to whatever the IP address is on your Internet connection.

Your domain (in this case, whatever comes after the @) needs at least either an A or MX record so that the receiving server can check the authenticity of your domain.

Also when I send a mail from the internet to my server nothing is being received,
Do some testing to and from your server with telnet. An example from your server might be as follows. You should substitute your own info. Remote server responses are italicised. Swap the obvious bits around for testing into your server. This lets you emulate what a mail server does, and might give you some clues as to where it fails (like, are your ports really open, etc).

telnet 25
