DML-Labs/MailTub ? reverse-engineered prompt

Build me a self hosted disposable email app that I can run as one simple binary or in Docker.

I want it to create temporary inboxes instantly, show incoming mail in real time without polling, and let me open messages in a clean web app with inbox, message list, and message detail views. It should support random inbox names plus custom ones, let me keep a few inboxes open at once, and let me choose how long each mailbox lasts.

Please include an admin area that is password protected, basic stats and mailbox management, plus a way to clear expired mailboxes. I also want a simple command line tool for creating, listing, reading, watching, and sending mail so I can use it without the browser too.

Make it work with SQLite, store data locally, support SMTP with STARTTLS, and include a mobile friendly interface with dark and light mode. If you need to look up anything current while building it, go ahead and check the docs online.
