Your DNS is not working.

Could be the DNS as Lync Davis writes but to elaborate somewhat:

It's not enough to have the DNS in the server itself. At a standard setup that will only be used by the server to find itself. Senders must also be able to look up the mail server's full domain name which means that you must have those records in a public DNS server so that clients sending mail can look up the server. Local clients might get settings via DHCP to use it as DNS server and if it's accessible from Internet on port 53 it could be used as a public DNS server (set in the settings for you domain at the registrar, by them or yourself).
