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

Mailserver 1: (
Mailserver2: (

SPF record: v=spf1 a mx ip4: ip4: ip4: ip4: ~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.
