The tricky bit here is "accepted by other email service providers". This depends a lot on the IP you are using, on the reverse DNS, DKIM/SPF settings, your ISP and "neighbours" reputations, RBL listings etc.

It's not just a case of distributing postfix and a nice UI on top. That's what makes email difficult nowadays.

I tried doing this a long time ago, and eventually gave up exactly because of this. I self host a lot of things, but self hosted email has always taken up a disproportionate amount of my time. At some point it's just not worth the headache any more.

I ended up ditching the self hosting route and went with an Exchange Online hosted email subscription at $5 per month and never looked back.

Well, it's not THAT hard. Find a good host with clean IPs, check the IP against RBLs before embarking on running your own email, if it's listed demand a clean IP instead.

It's not the easiest thing in the world, but it's far from brain surgery.
