mail server error settings

Hello,

This information is for the system administrator of your mail server.
After payment of the order I have not received any supporting letters. I started to find out the reason and see that you do not have a mail server is configured correctly.

in the domain zone following mail server registered the north:

hobbyking.com. 300 IN MX 30 smtp.asia.secureserver.net.
hobbyking.com. 300 IN MX 6 aspmx.l.google.com.
hobbyking.com. 300 IN MX 29 mailstore1.asia.secureserver.net.
hobbyking.com. 300 IN MX 7 alt1.aspmx.l.google.com.

and the letters come with the IP:

72.32.128.238
23,253,122,165

Firstly, these IP addresses do not match from the domain zone.
Second, these have IP Owned of the reverse zone.

Chances are most of your customers' messages are not getting through.
