Your experience may not be typical. I ran mail servers before office 365 was a thing, and I often had to get off block lists. There are stories on HN about it being worse, now that you have to request unblocking from MS and Google. Yours is the first comment that doesn't complain.

Nah, I have the same experience as the GP, and in every HN thread about email self-hosting, there are a number of comments along the lines of “I’ve been self-hosting my email for 10-20 years and never had any problems”. My SME employer also self-hosts without issues.

Experiences obviously differ, but it’s unclear where the differences stem from, apart from long-term IP reputation.

It is potentially more of those with problems are more likely to speak up than everyone else just posting "works fine for me" a thousand times over.

I haven't had much deliverability problems with self-hosted things. I set it up right, and I get the emails I expected to get. So there's now two of us saying "works fine for me."
