There is a very good chance that an email server running on a "home" IP address block of any of the major ISPs will be blacklisted.

True. If your ISP won't remove your IP from the blacklist, you could probably use a commercial service (a la Amazon's SES) for outbound SMTP while running your MX and mailstore at home. That would have somewhat different privacy tradeoffs, but it's not that different if you expect most of your email recipients to be hosted elsewhere... I may try this.
Indeed. If you want to be secure, you need to keep your email server at home, or in some other location you trust, and make sure all communication on the net is encrypted. That way, if an adversary wants your secrets, they will have to burgle your house.

True, because it takes effort for GCHQ/NSA/whoever to look at your server, which they probably won't do.
> Going beyond that to something with a whole lot more encryption and less of an ability for hosting providers to read your data would really require a product dedicated to that end: that is hard to get right
That's what I'm working on.
