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
Mailserver 1: mail.cybersharks.net (220.127.116.11)
Mailserver2: mail2.cybersharks.net (18.104.22.168
SPF record: v=spf1 a mx ip4:22.214.171.124/24 ip4:126.96.36.199/24 ip4:188.8.131.52/24 ip4:184.108.40.206/24 ~all
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.
