100%. I’ve been running my own mail server for 10-15 years now and you’re spot on. I’ve wanted to migrate it to a more modern platform but I’m loath to relive the process of configuring postfix and dovecot. DKIM/SPF and Let’s Encrypt certs for IMAPS were also a bit of a headache to get sorted, and warming up the sending IP so gmail would stop sending me to spam… but once that’s all sorted it’s been very very hands off. I log in once in a blue moon to update it but otherwise it just sits and does it’s thing.
