"You can then get shotgunned by spam filters, too"

Have you had that problem and weren't able to get by it? I've had IP changes over the years and while it's taken a small bit of work to get the new IP accepted (in some places most places don't seem to care) I'd say it's hardly a show stopper. Of course all the email deliverability people selling products and services in that market want to make you believe you'd be a fool to roll your own.

Of course if you get a VPS with some IP address that someone used to spam sure you have a problem. The idea is to do your homework and not have any of the obvious problems. (You can run the IP by the blackholes to see most issues.)

Also (not a comment directed at you by the way) I love the way a forum such as HN where people spend all sorts of time doing things just for fun seems to have a problem with the "work" involved in doing something that actually has value or might take a bit of work in order to solve a problem that they have.

The downvotes seem to indicate a reaction such as "wow what a stupid idea why would you run your own mail server hey you can just use fastmail that's what we all use".
