I've done this a couple times, and I think it's sufficiently difficult that if in the future I were hiring for a Linux sysadmin, I'd have them set up a mail server (that doesn't get spamfiltered) in less than 24 hours. I never got spam filtered once DKIM/SPF/rDNS/DMARC were properly configured. I think _this_ is the myth that Big Email spreads. Linux mail servers are hard, but getting past filters is actually not hard. Spam filters are really good today not just in their true positive rate but also their true negative rate. Given that a lot of services use your email as a 2FA mechanism, I wouldn't want to use a self-hosted mail server as my _only_ personal mail. You have to have a good reason[1] to make the time and maintenance commitment.
