If you read the post I linked, I have the correct DMARC, SPF and DKIM records and signatures happening. If I send them to my old University (google) account, I see all that get verified and correct. It doesn't really help. I suspect part of it might be that it's on a Linode and might be sharing a subnet with other spammy machines. That's probably why MailChimp owns a class C and refuses to sell any of it. |

Do you host an https site on the same domain? Is your mail server responding to ipv6? (I hear this can be a problem)
