Title: It seems to me that email and calendar data are so personal that you shouldn&#x27;t have to trust someone else to store and handle it for you. Yet when I try to find a way to host it for myself I get scared of the trickiness of the setup or the amount of maintenance required. Am I just looking for all the wrong things or is it in this day and age not possible, even for a reasonably tech savvy person, to host your own email and calendar securely? With securely I mean secure from all adversaries except for maybe nation-state adversaries.
[edit]
Like many people have pointed out in the comments an even bigger problem is being blacklisted by other ISPs. Any ideas how to deal with this while still maintaining control of where your emails are stored?
