No, Microsoft especially has started taking the policy that email coming from a domain without a long-established reputation is automatically spam, and you have to jump through hoops to get it delivered. But all of the major providers have started doing this.
I've been running my own mail server using the https://mailinabox.email service on my own domain with a fixed IP for six years, and I still have delivery problems. I am not a spammer, a quick look in Thunderbird indicates I had 28 email conversations in the past 12 months.
