Show HN: I wrote an email app that accepts only one sender per inbox

Infinite inboxes, including prefixes where you don't have to create inboxes before you use them -- they self create when you add a suffix.Three types of inboxes: - One sender. Locks to the first domain to send email (except gmail, outlook, etc where it locks to an email account for obivous reasons. It bounces everyone else. - Temporary. Lasts for a while (24h, 7days, etc) then bounces. Received messages stay or go as per your choice. - Prefix. The most powerful. Declare a prefix like "service" and then invent any suffix, like "service-netflix" or "service$bank" and it creates a new one-sender inbox locked to whoever wrote first.Bring you own domain. Bring your own AI (MCP server ready). Forwarding.Please help me test it. Comments URL: https://news.ycombinator.com/item?id=50090932 Points: 8 # Comments: 2
