Good summary. From my experience if your server has been around long enough and your IP is dedicated and stable, you can get away with skipping some of that (eg. haven't had to do a blacklist removal request in over a decade). Another little perk to owning your own server that hasn't yet been mentioned by others is you can dictate policies (eg. mailbox size, accounts allowed to receive commonly-restricted file types, max attachment size, etc).
