I had this problem self hosting but was able to remediate it by making sure my server was doing all the smart modern things like dmarc etc... there are some good resources on HN from others who've set up all the right things.

Of course, this all happened after I got bitten during a job search and had most of my applications hit spam folders ಠ_ಠ

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.

Interesting. I am on Linode as well, that sucks.

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

Can you recommend a good resource for "how to set up your mail server like it's 2017" for those of us who would like to self-host but don't want to spend 6 months figuring it all out?

From recent memory this post covers all the stuff I did with my server: https://news.ycombinator.com/item?id=11946756

There are a lot of testing tools you can run mail through as well to see how well you score.
