I've been using Mail-In-A-Box for self-hosted email for about a year and a half, and it's been very low maintenance and fairly easy to setup. It did take some time at the beginning to get all of the DNS stuff right, but that's a one-time cost. And, so far, I haven't noticed any spam binning once I finally got the DKIM & SPF stuff correct. I guess part of it could be that since I'm using a lesser known ISP my IP hasn't been blacklisted as part of a large block. If you still have an interest in self-hosting email, I highly recommend Mail-In-A-Box (https://mailinabox.email/ https://mailinabox.email/).
