alt Hacker NewsIn my experience they will mark your e-mails as spam for no sound reason at all. I run my own MX, for myself personally, and my e-mails to friends using Gmail regularly gets classed as spam as soon as it's been "long enough" since my last mail. My MX does everything by the books, ticks all the boxes, never ended up on any DNSBL etc. Their behavior is effectively a form of systemic sabotage.
Yes absolutely this. I've put so much effort into making sure I tick all the boxes and yet I constantly wonder if my email is getting delivered. This feels anti competitive to me. It's Google constantly telling me, give up, you know deep down you should just use Gmail.
