Apologies for cross-posting about the same issue here and on github. I figured more people might recognise the issue and can help solve it with me.
I have read-up and followed instructions found here and on github and happy to say I get passes everywhere (MXtools. mailtester…) yet still get send to spam folders at Gmail, Outlook.com and Yahoo Mail. Protonmail appears to be happy though.
I am using a VPS hosted with Scaleway and the IP address is not blacklisted anywhere. Even the range looks OK from my limited checks.
