Topic: What's wrong with my headers? Counted as spam on gmail, outlook, etc

I am so confused. GMail, outlook and iCloud mark all my emails as spam. I checked with glockapps and I'm not blacklisted anywhere. GMail also says I'm passing with:

SPF:    PASS with IP 157.230.135.73 Learn more
DKIM:    'PASS' with domain pancake.email Learn more
DMARC:    'PASS' Learn more

I also believe my reverse DNS is working fine (domain is pancake.email). And yet I am consistently being marked as spam. Here's some mail headers from my latest test:

Short answer, no clear solution besides adding required DNS records.

- We don't know how Gmail/Hotmail/Yahoo/Outlook detects spams.
- Seems they also judge based on IP reputation, if your IP or domain name appears recently but not before, it's considered as low reputation and may be marked as spam.

that mx record must use "fully qualified domain name of a mailserver"
