Gmail marking all my sent mails as "spam" despite all tests (DKIM, DMARC, SPF) being passed...
So apparently all the emails I am sending from my mail server (Postfix) are being classed as spam by Gmail. Gets me very frustrated as all the tests (DKIM, DMARC, SPF) have been setup correctly and all pass in Gmail. A reverse DNS record is also present and fine. Any advice on what to do next? Or what I might do to fix this mess?
