Returned emails no Valid PTR
Hi,
Just starting today, all emails from my 2 domains (hosted elsewhere) to comcast.net accounts are being rejected "Comcast requires that all mail servers must have a PTR record with a valid Reverse DNS entry. Currently your mail server does not fill that requirement"
I checked many lookups (dig, SMTP, rDNS) and everything look fine.
marinehomecenter.com = 199.189.105.37
Can someone point me in the right direction?

Hello danamacomber,
Welcome to the forum.
To your query I would suggest contacting our Security Assurance Group to check/remove any block list on your domain.
This is their Block list Removal Form link.
Thank you
