Have been using Mail-in-a-box [1] for about 5 years [1]. I haven't done any maintenance for at least 3 years, besides occasionally clicking restart in the admin webpanel every time it does serious security updates.
I don't send a lot of emails from it, but the ones I do are delivered.
It's a relatively steep learning curve if you're not getting paid to do it. However, in my case, I have been running my personal mail server on a trusted VPS host for well over a decade now. After the initial setup, there is really nothing to do except for regular Linux updates/upgrades. I run postfix, dovecot, roundcube, and rspamd. All of the configuration is in Ansible, so if the host goes tango uniform, or if I want to move it elsewhere, downtime should be minimal.
There are a few open-source one-command mail server deployment solutions that do all of the heavy lifting for you. Some of them might even be pretty good. The problem with those is that if you don't understand how your mail server is put together, you're completely stuck if it breaks.

I just use Postfix. I originally ran on NetBSD. I have an alternative approach for spam, so I have no anti-spam tools.
https://www.xmox.nl/ is pretty good single binary mail solution for personal email hosting, it not too many features of modern webmails are needed.
Self hosting a mailbox is easy - getting email back out is the hard part.
