Thank you for this perspective. I've been hosting my own email for about 25 years and have never had significant problems delivering to any of the large providers. A couple of months ago I migrated from one VPS host to another. I'd been putting this off for a long time, in part because of what I've read on HN about how difficult it is to self-host your mail. I finally took the plunge a couple of months ago, expecting to find the new provider's IP space unusable & having to relay via the old MTA/start relaying via a commercial MTA; but to my surprise, it's been completely smooth sailing! Maybe I've just been lucky with the nature of my setup: a small number of mailboxes and domains used for personal/small business use. Certainly if I was sending bulk mail or significant amounts of transactional mail then I'd use someone else's service.
