However you do have to live with the occasional blacklist when you host on a VPS like I do. Some idiot in your IP range may get blacklisted for spam and then you get caught in it. It’s generally temporary.
And there are some corporate policies that will flat out reject emails from you which is fun.
I’ve probably spent less than 10 hours over the last 5 or 6 years on maintenance.

This is what keeps me away from self-hosting it, though. As long as there's some possibility that my ability to deliver email could get nuked, all because someone else made a mistake, it's not worth it to me, especially since using / sending email is mandatory for doing most things. I guess I'm just not really willing to take that sort of risk
Or you can pay to get off the list.
Not all email services use blacklists anyway. Bit of a racket.
You can mitigate against it by hosting on a dedicated IP.
But I understand the risk. It’s really annoying when I send someone an email and they call me some days later wondering why I hadn’t sent them an email. Failures are often silent on the sending side.
It’s not for everyone. There are risks.
