How to gather feedback?

Hey everyone! First time posting here, I have created side project as made it open source.

I wanted a simple self hosted disposable email solution for privacy and control, but I could not find one that fit my needs. So I built TempFastMail. It lets you quickly spin up temporary inboxes on your own server, receive emails without giving away your real address, and keep everything fully under your control.

Code and details are here: https://github.com/kasteckis/TempFastMail

I wanted to ask for ideas and feedback, maybe do you see what's missing and what could you add or suggest?
