Emails to me.com blocked by DMARC policy

Hi Guys,

Can anybody help with this problem. A client has an on premise Exchange 2010 server. They can not email to users at me.com as their emails are blocked by yahoos DMARC policy which I have reviewed. We have ensured the sending servers IP address is in the SPF record and that the PTR DNS record from the sending servers external IP address matches the string the server users when it connects. The external IP address of the sending server does not come up in any blacklist checks. Can anybody suggest what else needs to be in place or checked to allow this email flow?

Thank You

Ray Pinkerton
