Is it? Last time I tried to self-host my email I did. I had DKIM, DMARC and SPF set up correctly as verified by multiple sites, but I couldnt't get reliable delivery to any Microsoft-hopsted mailboxes. Every other provider I tested was perfectly happy with my mail, unfortunately MS is too big a provider to ignore them.

Maybe it was my IP, but I cycled a few with my hosting provider and none of them made a difference. If I am unable to reliable obtain a 'trusted' IP, what good does it do?

I switched to hosted email and all my delivery issues were gone.

There are tools that can check if your IP is on a blacklist [1].

Also, my experience with self-hosting email is that if you get people to email you first from their domain, and you reply to them, then you are not going to be blocked. Of course, this won't work if you send a lot of cold emails.

That's true. I have a Class C IP range and a domain registered for 30 years and yet Gmail still started ignoring my email server a couple of years ago...
