I'm going to add "bullshit" to the first. I've gone 2 decades running a few email domains on my home servers, on 3 different ISPs. Its not rocket surgery.
Same here. Static IP though. I did set up another experiment with a haproxy vps just to see if I could do it if I lost my static IP, worked perfectly done that way too.
Fail2ban, pfblocker, and soamassassin work great.
My sending got blocked from dynamic IPs, maybe things have changed though
I've been running one with a dozen or more users on bare metal at home for the last two years. A little bit of spam but otherwise fine. No deliverability issues or anything.
All the ISPs I've used block the relevant ports.
