Have you actually hosted an email server on all five of those? As you mentioned in your other comment, it can be very helpful if your VPS provider is able to respond to support requests asking Microsoft for IP addresses to be whitelisted. I can't imagine all VPS providers would be so helpful but you didn't mention which one you were using in that comment.
- lifty 5y agoI’m hosting my email on Scaleway for 4-5 years and have no issues with deliverability. Last time I checked my email server was correctly configured.
- xarope 5y agoI'm hosting on linode, and once I had my SPF & DKIM records setup, things went a lot smoother.
