I have a domain with two mail server hosting several domains. I am having a problem emailing to Yahoo on the second mail server but not on the first. I have a feeling it is in my DNS setup but am not sure everything has been working fine up to 1 month ago. What should be mail dns setup for cybersharks.net<br />
<br />
Domain: cybersharks.net<br />
Mailserver 1: mail.cybersharks.net (208.31.0.50)<br />
Mailserver2: mail2.cybersharks.net (208.31.0.51<br />
<br />
SPF record: v=spf1 a mx ip4:208.31.0.0/24 ip4:204.118.153.0/24 ip4:205.160.50.0/24 ip4:205.160.51.0/24 ~all<br />
<br />
I have also tried the domainKeyEvent and that is a no go as that has to be the bigest load of crap I have ever seen.

DNS Setup

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
