I wrote my own receive-only Haraka-based server. The web UI is pretty simple: x-y matrix of small blocks representing received emails with basic info (subject and from address). A column is the account. Clicking an email block brings up full text or html mime content (not rendered). It’s setup to receive everything that’s sent to it, which means I occasionally have to delete rando spam. TLS is setup too. But it’s an interesting system because you can keep tabs on what exactly you are receiving per service (e.g. using instagram@mydomain.com), and maybe one day will tip me off to services giving away email addresses. Otherwise I’m using gmail for personal sending.
