If you have concerns for privacy, find a paid service you trust. Hosting an email server yourself is a great learning exercise but you'll be forever playing whack-a-mole with spam and wondering if your setup is actually properly secure and waiting for the day you get hacked. I did this myself for a few years and at one point had very few deliverability problems, then one day out of the blue I ended up on a black list and started getting complaint emails. After that it was either rebuild on a new ip address and start again or choose a paid provider and move on, I did the latter and opted for Fastmail.
