In case you think this is a duplicate, trust me, it's not.
Problem: All personal emails (not newsletter or mass email) sent from my website domain like john@mysite.com is going to Gmail Spambox (and Outlook.com too). Even simple email like "Hi, how are you doing?" with little content and a signature get marked as spam. Tested with two new email addresses. Domain is 1 year old and the site is not even launched yet!
My Email Server Settings:
- SPF: Pass
- DKIM: Pass (2048 bits key length)
- DMARC: Pass
- Blacklist: No for IP and domain (Checked on multitude on sites)
- rDNS: Done and pass
- Google Postmaster Tools: It keeps saying "No data to display at this time. Please come back later."
Anything else I should try? I'm running Postfix with SpamAssassin at AWS.
