It's addressed in the article:

> The elephant in the room is real-world deliverability. With self-hosting you risk not receiving mail or someone missing your mail. I accept this for my personal projects, but you may not. Keep this in mind.

Not self-hosting if you actually need email does not address the elephant that self-hosting email doesn't actually do email. I say this as someone who self-hosted for several years but had to give up because important emails were discarded. Until the deliverability issue is actually addressed, self-hosting is not viable for email.

I’ve been self hosting my email for thirty years. I don’t have any more deliverability issues than I do at work using a major provider. It is entirely viable.

I've never heard of "not receiving" as a problem. Does that happen in the real world? In what cases?
